Expert Results analysis

Your scan becomes a plan

A DEXA scan gives you numbers, but not direction. At Kalos, those numbers become meaningful. Every metric is interpreted in the context of your goals, so your fat, muscle, visceral fat, and bone density data translate into a clear plan for training and nutrition.

"A DEXA scan is only as valuable as the conversation that follows it. Having an expert walk my patients through their results has fundamentally changed how they engage with their own health. That's why I always recommend the full Kalos analysis."

Dr. Chris Threatt

Men's Concierge Health

"Kalos has become a trusted extension of how I care for my patients. I know when I refer someone, they'll be well looked after and given the insight and coaching they need to move forward with confidence."

Don't take our word for it

This the best place to get DEXA scans!!! I've had a few scans at other places and they pretty much just did my scan and gave me the report. Callum sat down with me for 20 min after the scan and gave me so many insights about my body composition that I didn't even know. Thanks again!

Miles H.

Such a great experience! I’ve absolutely loved the Kalos program. The team is super supportive and really knows their stuff. My experience with Harsh was very personalized and he has been a phenomenal trainer. The program made me feel comfortable from day one, and I felt stronger, healthier, and more confident every week. I've never been able to see visible results with any other fitness programs I've tried. Honestly one of the best decisions I’ve made for my health. Highly recommend to anyone looking for something that’s sustainable, motivating, and actually enjoyable!

Sarina R.

Always professional and incredibly knowledgeable staff. My results speak for themselves. I’ve never felt healthier in my life!

Phillip E.

This place is amazing! Me and my sister came here from Sacramento to get our DEXA scans. Shaun and Callum were so professional. Shaun went over our results and explained everything and answered our questions. HIGHLY RECOMMEND. See you soon for our follow up scan! ❤️

T M.

So much more than a DEXA scan. I left with such a complete understanding of my body composition and an actionable plan on how to improve. The whole team was extremely professional and I couldn’t recommend Kalos more.

Jordan T.

This was honestly an amazing experience to be able to see all my gains analyzed numerically. Also, Shaun made the experience way better with his attention to detail, analytical nature, and highly intelligent when it came to breaking down all the numbers and providing details to my overall body composition.

Wisely K.

My wife and I met with Lexy for our initial visit. It’s been a while since we did any full body scans and this has been on our radar for a few weeks. The Dexascan was quick (6 minutes each) and stress free. Lexy gave us an excellent, detailed overview of the results including specific things to work on. We’re considering the coaching package and see how it fits into our time and overall training. Definitely would recommend Kalos and Lexy for anyone interested in long term health!

Ron C.

I came here in October 2025 to get a scan and better understand my body. Joshua, the coach/trainer was awesome! He guided me through each step of the scan and the supports that Kalos offers and I agreed to sign on for a month of training, focused on nutrition. He helped me increase my protein intake with ease. During the 5 weeks, I nearly doubled my protein intake and I was asked to upload photos of everything I ate for 5 weeks. This was great accountability! This shifted my awareness and has put me on track for success. Joshua would provide excellent feedback, recommendations and was very motivating. The app also has personalized strength training workouts; however, I had just joined a crossfit type gym so I focused in on that instead. Today, 5 weeks later, I went in for a second scan and lost a little over 3lbs of fat and gained almot 3lbs of muscle and overall lost 1.3% fat. Prior to this, I was really struggling to lose weight and only watched the scale increase as I aged. This has helped give me tools to lose weight naturally vs. taking medication like so many are doing. I am grateful for the support Joshua provided. He is friendly, motivating and very knowlegeable. He shared they will be opening up a location in Campbell Pruneyard soon and I'm very excited to have a Dexa scanning resource closer to home. Go check them out if you're looking for meaningful data and support to meet your health goals! The entire process is extremely insightful.

Great experience at Kalos Palo Alto. Sophie guided me through my scan and was professional, friendly, and knowledgeable. I felt she really listened and understood my goals and worked with me to tailor a fitting plan. Highly recommend booking here.

Jonathan T.

My wife and I were very impressed with our visit to Kalos, Palo Alto location.Travis took the time to review our scans in detail, and his passion, kindness, and sincerity really stood out. He offered clear explanations and practical guidance tailored to us. Excellent service from start to finish.

Damir S.

Boy did we enjoy our experience at the Palo Alto Kalos clinic! And the information we received was eye-opening and valuable. My wife and I both had their DEXA scan, and then Sophie went over the data in detail and explained our findings. We both have work to do on our fat/muscle balance, and that’s exactly what we needed to know. We now have the information— and baseline scan data— to plan our exercise program over the coming weeks and months. Then we’ll come back at some point and repeat the scan and be amazed by the improved numbers, as well as our improving health! This service gives you a lot more than a traditional dexa scan, which has been used primarily for bone density. This gives data about body muscle and fat composition, including regional variations, and it compares you to national population data. If you are at all interested in your short and long-term health and performance, I highly recommend this service. Check out Kalos in Palo Alto!

Gregory C.

I just completed my first DEXA Scan at Kalos, and the entire process was pleasant and seamless. Joshua was exceptional: highly professional, knowledgeable, and kind. He took the time to explain everything clearly and made the experience very comfortable. I highly recommend Kalos if you are looking to gain precise insights into your body composition and are aiming for improved strength and overall health. A great experience!

Yvette L.

I went in for a DEXA scan with my husband and it was super informative - learned a lot about my body fat percentage, visceral fat percentage and my bone density. Sean was very knowledgeable and my husband and I decided to enroll in the coaching program and invest into making some changes in our overall health. Sean really hit it on the nail with his coaching and identified a lot of my weaknesses and played to my strengths to help the program be a success for me. I’ll definitely continue to use a lot of what he taught me moving forward until my next scan and hope to continue making more progress to hitting my goals.

Roxanne L.

I could not recommend more. My experience with Sean at Kalos was great! The scan combined with the knowledge provided after really allows you to have a better understanding of what’s going on with your body. Sean was a great and motivating coach throughout the 4 week program following my initial scan. Thank you for an awesome experience!

Chloe P.

I am so glad that I am with Kalos especially with Coach Sean. They practice evidence based science and base your program based on your Dexa scan and data. Every month I see progress and they spent a good an amount of time to sit with you to talk about nutrition, exercise , anticipated barriers and set up goals to set you up for success. I am looking forward to continue with my health care journey with them in the next year. It’s money well spent and the best decision I made in terms of my health.

Kathy B.

Met with Lexy to try out the full body scan. It's really impressive how much knowledge we got from the Dexa scan. Lexy was very knowledgeable about body metrics and she made me feel super comfortable while learning about my current state and how I can improve.

Jennifer D.

Came here on a Wednesday afternoon, parking was actually not too bad. We were a bit early, but it wasn’t a big deal bc there’s a nice couch to wait. When it was our time slot, we were promptly placed into the DEXA. It takes 6 mins total and then afterwards we got a full breakdown of the whole scan. Josh was great! Very personable, easy to talk to, and very knowledgeable. Would recommend!

Riceley Y.

Had a fantastic experience with Lexy! She is incredibly knowledgeable and walked me through results with detail. I would highly recommend doing a baseline scan and then returning in a couple months. Much appreciated!

Raven C.

I had a great, eye-opening experience today at Kalos Palo Alto, where I had a body composition scan. I worked with Josh who walked me through my results, explaining everything in terms I could relate to and understand. Also, I learned about the overall program and coaching services available to me, which didn’t feel like a hard-sell. If you are wanting to learn about your health and fitness potential I definitely recommend giving this place a visit.

Cepeda C.

Scan was quick, and Lexi gave us a ton of actionable and useful information. We will definitely make this a part of our yearly routine. Note: the information from this was significantly more accurate than anything I have done.

Jan C.

Booked this place randomly and we couldnt have spent my Sunday afternoon any better. Walked in and had a session with Lexi and she is the BEST !!! The scan itself takes 6minutes and we as a couple had a long conversation after the scans. Lexi explained each and every number , how to get it better, set us possible goals and how to move ahead. This was a great session and definitely set us up for the year and how to work on our goals.

Atanu S.

Wow!! First time at Kalos and what an amazing experience. My husband and I have recently started to be more aware of our fitness and health. So we decided to try it out. Our appointment was with Travis and he really dove deep into our analysis. He really opened our eyes to our health and where we need more improvement on. Facilities was clean and really respected privacy. Really happy that we found Kalos and met Travis. They have helped us to reevaluate our health and make the needed changes to our lifestyle. Thank you Kalos and thank you Travis.

Seda A.

Kalos is a fantastic place to try if you’re serious about making changes to improve your lifestyle and overall health. They provide an all-inclusive program with both nutrition and personal training. I worked with Travis who helped me through some of the physical limitations I had. He is exceptionally motivating and really caters a plan meant for you. Having a regular DEXA scan helps make sure that you’re on track and keeps you focused. It’s really encouraging to see major changes after consistently working out and applying changes to your diet. In six weeks, I was able to not just lose 4lbs of fat, but I also gained 9lbs of lean mass - this was exactly the kind of result I was looking for! Definitely recommended to those who may have no idea where to start, but even those who regularly work out will learn something new.

Carl V.

Lexy Nevis completely redefined my expectations of what an exceptional coach can be. This was my first experience hiring a professional, and it exceeded every expectation. Lexy brings a high-energy, positive attitude while still pushing you to new levels of performance. I genuinely wouldn’t have hit new personal bests without Lexy in my corner. I can’t recommend her highly enough.

Josh was absolutely amazing! He was extremely knowledgeable and incredibly detailed throughout the DEXA scan process, taking the time to explain everything clearly and thoroughly. You can truly tell he genuinely cares about people’s health and helping you reach your goals. His professionalism and passion for what he does made the entire experience comfortable and empowering. I highly recommend working with Josh if you want accurate information and someone who is truly invested in your success!

We had a really positive experience with our Dexa scan at Kalos Health. Sophie was incredibly thorough, knowledgeable, and encouraging throughout the entire process. She took the time to walk us through the results in detail, answered all of our questions, and made sure we fully understood what everything meant for our health goals. We never felt rushed or pressured — just supported and informed. Although we weren’t able to move forward with the program due to our current financial situation, we truly appreciated how respectful and understanding she was. The experience itself was valuable and empowering, and we would absolutely recommend Sophie and the Kalos Health team to anyone considering a Dexa scan.

Lyllian L.

I'd heard about DEXA Scans through a close friend in late 2025. These scans give you information on lean muscle mass, fat, visceral fat, and bone density. All of these factors have can have a significant impact on health and well-being, and often need addressing sooner than later. My wife and I had spare FSA money and decided to try it out. I learned I was in very bad shape due to my lack of exercise and terrible diet. Thankfully, we were paired up with an amazing performance analyst, Lexy Nevis. She guided both of us on what our scans meant, and how to fix any issues with our bodies. I have been working with Lexy in a program since early November 2025. She has been incredible to work with. Since I've implemented her diet and exercise plan, and coach with her regularly to make the best of my program, I've gained 11lb of muscle, lost 4lb of body fat, and have seen slow but steady improvements to my bone density. Though it is important to be disciplined in these kinds of programs, having a great coach is very much appreciated. She is knowledgable, straightforward, and amicable. She's been easy to work with and listens to my questions and requests. I'm grateful to have her as my performance analyst. Shoutout to Lexy for being the GOAT! 🐐

I worked with Lexy at Kalos in Palo Alto for several weeks and had an excellent experience. From the beginning, she was incredibly welcoming, enthusiastic, and professional. She created a supportive environment while still keeping me accountable, which made a big difference in staying consistent. One thing I really appreciated was how well she worked around my busy school schedule. She was flexible, communicative, and made the program feel manageable even when my weeks were hectic. It was clear that she genuinely cared about helping me succeed and took the time to check in and adjust things when needed. Unfortunately, I wasn’t able to continue into the next round of the program for financial reasons, but Lexy handled that conversation with so much understanding and grace. There was never any pressure, just encouragement and kindness. Lexy is a fantastic coach and a great representative of Kalos. If you’re considering working with someone there, I would absolutely recommend asking for her.

I highly recommend Kalos. My wife and I went to the Palo Alto location and based on working with Sophie, their team is knowledgeable and very professional. Their facility is well set up to allow for privacy during the scan and during the evaluation. Sophie is very experienced on reviewing and explaining the results, putting a program together to reach out goals, while keeping in mind the reality of life (work, family, personal goals, competitions). The Kalos App is very complete and easy to use. I’ve used other apps to track progress and workouts and this one is by far the best I’ve seen. The calendar is easy to read, works are easy to follow, sample videos on the same screen, and weight tracking with history and graphs display. It would be great for Kalos to have a studio where clients can workout or build a community to reach out goals and step up accountability. I went through their program and successfully increased my lean body mass and strength, definitely a success. Thanks Sophie and Kalos team.

Hello to anyone considering a dexascan with Kalos! My girlfriend and I actually did the 1 month body recomp just to kind of see if it would help or even do anything towards our own personal fitness goals and to our surprise it ended up changing our entire mindset around the foods we are putting in our body and the way we train. Let me first start off by saying thank you to our GOAT Sophie Klube! She was there to explain our scans in so much detail, but also in such an easy and digestible way! Normally I get confused when words that I’m not used to get thrown around, but she explained things, then gave an example of the thing she just explained. Top notch stuff! Also, the way she showed us dieting was so easy to transition to! We never really felt restricted to eat certain things, but also just not eating empty calories! After completing our month of body recomposition we cut our visceral fat, lost some lbs on the scale, gained a good amount of lean muscle, but the best thing we received was the tools to continue living a healthier lifestyle I 100% recommend getting a dexascan if you’re trying to: - sleep better - have more energy - achieve fitness goals - change your life

Paul A.

We had an excellent experience during our DEXA scan, and a big part of that was thanks to Lexy. She was professional, knowledgeable, and made the entire process comfortable and easy to understand. She took the time to walk us through the results in a clear and helpful way, which we really appreciated. Overall, it was a great experience, and we would absolutely come back again. Highly recommend working with Lexy!

Selena L.

From start to finish, my DEXA scan appointment was a fantastic experience. Lexy was incredibly attentive and thorough, taking the time to ensure I felt comfortable and informed every step of the way. Her ability to break down the results into something easy to understand really stood out. I left feeling much more confident about my health insights and would absolutely come back again. If you have the chance to work with Lexy, I highly recommend it!

Very useful data driven fitness business. They have their own very modern DEXA scan machine which uses very low-dose x-rays to measure things like muscle mass, visceral fat, bone density and other very useful fitness and health metrics. We’ve worked with three of their staff and all were great. They are bright, graduates of top universities, have good teaching skills and were not hard sell on anything. I thought I had everything pretty well figured out but KALOS showed me that I was not eating enough protein to get full benefit from the weight training that I have been doing. I followed their advice and saw a significant increase in muscle mass and a decrease in visceral fat. They give very useful diet coaching and it’s not just generalities. We currently work with Alex Shultz in Palo Alto who does our scans and explains the results and coaches us on how to get further improvements. He is very smart, friendly, science oriented and really good at explaining what you need to do to get healthier in a measurable way. We went to San Francisco to have a session with Morgan Mitchell who was very helpful in coaching us on how to improve our exercise form to achieve better results. She’s super fit, smart, friendly, and I could feel the beneficial results of her coaching when I did workouts afterwards. There is something about knowing you are going to get a DEXA scan in the future that makes you more disciplined because you want to see improvements. It’s like losing weight and working out before the senior prom, something like that. They don’t push supplements. They don’t do a hard sell on the renewals. They just give you very useful information and it’s all up to you what to do in the future.

Mark J.

This is what I’ve been looking for. I finally got tired of all the apps that make promises they can’t keep. This not only reveals your body composition but they have experts to help you with workouts and nutrition as well. Looking forward to starting this new journey with them.

Brett W.

Had a great experience getting to know the breakdown of the body fat and different elements of body. Their plan for primary and secondary days of workout sounds promising. Definitely looking forward to take the plan and see the results.

Sreenath D.

The guys were great! The procedure was stream line, and they explained my results really well. They have a great program structure using the supplemental dexa scan to help guide in reaching fitness goals. I’m friendly and comfortable atmosphere

Austin P.

Highly recommended! Ben provided great insight into my current body composition and how to improve key metrics for body percentage fat, visceral fat, lean muscle, etc. I was surprised to see a difference in muscle mass in my left versus right side arms/legs and looking forward to seeing how these numbers change when I return next time

David K.

I had an amazing experience at Kalos! This is a DEXA full-body composition scanning studio that gives you a detailed breakdown of your results and can create a personalized program based on your scan to help improve your overall health, strength, and longevity. Ben was our performance analyst and he was seriously the best. He was incredibly informative, knowledgeable, and so patient. We had a LOT of questions and he didn’t leave a single one unanswered. What I appreciated most was that it didn’t feel salesy at all; it genuinely felt like Ben is passionate about health and helping people understand their bodies and improve their wellness. The location itself was brand new, super clean, welcoming, and made the whole experience feel comfortable. I was a little nervous going in, but they offered refreshments and the process was surprisingly fast and easy. Pro tip: book the couple scan for the savings (even if you’re not a couple; I went with my dad). They also have a few other locations, but this one being new was such a vibe. I 100% recommend booking at least once; it’s so worth it and honestly eye-opening in the best way!

Cheyleen C.

I went to the Kalos San Jose at the Pruneyard. Easy to locate and lots of parking available. The office was very clean and professional. The scanning table was surprisingly comfortable and the scan process took about 6 minutes. After the scan, I sat with my assigned performance analyst, Chris. He was fantastic -super thorough and informative and his enthusiasm and passion for health and fitness was obvious. The information the scan provides is unbeatable. It breaks everything down and leaves it all out there so you really do know how healthy you are and areas where you can improve. They also can provide support for you for next steps if you need it. I would highly recommend getting a Dexascan at Kalos if you are serious about your health. You got one life - you owe it to yourself to make it a healthy one!

Lyja L.

Great experience with my DEXA scan! The process was quick, easy, and the staff was very professional and helpful. The results were detailed and gave me a clear understanding of my body composition. Highly recommend for anyone interested in tracking their fitness and health.

Busra B.

Great experience at Kalo! The DEXA scan was quick, easy, and very informative. Staff were friendly and explained the results clearly. Highly recommend if you want an accurate look at your body composition.

Tiffany T.

Fast and efficient procedure and very friendly and welcoming staff. I’d like to track my numbers to be aware of the changes in my body as I age and be proactive about my health and welness, and Kalos makes it easy to do.

Iryna I.

Had a great experience with the intro discount offer they gave. I just got the basic scan. Callum was very helpful and respectful of explaining their services and gauging my needs without being pushy. I’ve also heard great things from friends about their other services. Would definitely recommend coming to this location if getting a dexa scan

Shane S.

Quick and easy scan with details body composition 1. Ben was very helpful and cordial throughout the visit explaining everything 2. Got the results very quickly with detailed report 3. Booked the second scan to track progress Things to note 1. Go 5-10 minutes early as their schedule is very tightly packed 2. Don't wear anything with metal. Gym wear is the best 3. Fill out the screening form for quick turnout

Fayaz

Having traveled the world—from the dojo of Rex Kwon Do to the highest glaciers of the Tibetan Himalayas—and training with two-time American gold medalist Irving Blitzer and master martial artist Ra’s al Ghul, I can confidently say that nobody does it better than KALOS. The combination of a custom-tailored exercise and nutrition plan through their app, along with trainer guidance and data-backed insights from DEXA scans, has proven to be extremely effective in my journey to change from man to beast. I’ve seen impressive results so far and am well on the way to achieving my overall goal. I’m only halfway through, and just yesterday I was able to carry six Trader Joe’s bags full of nonfat Greek yogurt (that’s 56 lbs) up 10 flights of stairs in my five-story walk-up without even breaking a sweat. What I find especially helpful is the autonomy and flexibility of the program. They’ve helped me select exercises I enjoy at a frequency that works with my busy schedule, while providing professional, insightful guidance and staying readily available for questions along the way. For anyone ready to commit, KALOS will absolutely give you the tools and resources you need to succeed—it’s worth every penny.

Brad G.

I had an excellent experience at Live Kalo for my DEXA scan. Jackie was incredibly professional, knowledgeable, and took the time to explain the results in a way that was easy to understand. She made the whole process seamless and comfortable. Highly recommend seeing her if you're looking for an accurate body composition analysis!

Veerendra R.

I’ve been getting DEXA scans for a while, and this experience was exactly what I’ve been missing: spot-on coaching to help me understand my scan results and create a plan for building muscle. I met the CEO, and he personally crafted me an exercise plan that I will try for the next month then come back. Love it!

Jordan T.

Kalos is by far the best DEXA experience I’ve ever had. Harsh and his team have a wealth of knowledge on all things fitness and nutrition. If you’re looking for wholistic body metrics, this is literally the only service you need to consider. I’m booked to come back quarterly! Highly recommend.

Bhushan P.

"These guys are really taking DEXA scans to the next level! I got a customized a workout and nutrition plan based on my scan results. Exactly what I’ve been looking for. All of their staff are certified personal trainers, and they explained my results to me in person. I learned a lot more than I would’ve trying to read it on my own. If you’re looking for a scientific approach to fitness, this is the place."

Phillip E.

KALOS has an amazing workout app that not only tracks my workouts and the exact amount of weight I’m using but also provides comprehensive nutrition tracking. This combination allows me to have a well-rounded approach to fitness, ensuring that both my exercise routines and dietary habits are optimized for the best results. Highly recommend!! :)

John J.

I've known Harsh since our time at Harvard and again as coworkers at Facebook/Meta and I fell in love with the concept since he first had the idea. The attention and focus he gives is unlike any I've ever had. Fundamentally having the data he collects with these sophisticated DEXA scan puts his Personal Training in a league of its own.

Neil

It’s crazy what a lot of nutritionists, health professionals, and physical trainers try to tell you without truly knowing what your wants or needs are with minimal results in the end. KALOS didn’t tell me what I want to hear, they told me what I NEED to hear. Their methods of using factual data analysis, DEXA Technology coupled in with honest training advice nutritional advice is life impacting. I learned things that doctors in the past haven’t been able to tell me. This IS the future of physical training.

Ahmad A.

These guys not only helped me understand my scan results, but also gave me great advice on how to adjust my workouts to build more muscle. Actually the CEO personally designed an exercise plan for me. Super excited to try it out over the next month. Definitely recommend!

Sean N.

I really appreciated Harsh's meticulous approach. He took time to really understand where I'm at with my injury and where I want to go with my personal athletic goals. Getting the scan was informative and gave me more confidence in where my body is at currenlty, and will help me see the direct impact of the exercise and nutritional intervention suggested by KALOS in 8 weeks.

Samira D.

I visited Kalos and felt empowered by what I learned! I ate well and exercised frequently before, but now I have goals and purpose! I know what I am trying to improve and how I am doing it. Amazing experience!

Michael S.

I’ve been a Kalos client now for three weeks and I couldn’t be happier with the experience so far. The DEXA scan was a reality check. I went in with assumptions about my body fat and muscle mass that ended up being completely wrong. The personalized workouts and nutrition plan have been great — I’m already seeing strength improvements. I’m looking forward to getting my next scan soon.

Akshay S.

Kalos Health is the best DEXA scan service I've received in SF. Previous scans I've done just give me a print out with some data, but Kalos's team of fitness experts was able to explain my results and provide actionable insights. Looking forward to the future one! Thanks Kalos.

Besart Ç.

Genuinely incredible. I've gotten a dexa scam from a few other places and what really sets these guys apart is the personalized experience as well as the trainers that build a tailored plan based off of your results. It's a steal for how simple they make protecting your health.

Anshuman S.

Kalos Health has been a game changer in helping me achieve my fitness goals. The simple to follow workouts and nutrition advice paired with data rich dexa scans is by far the best way to hit your goals. Highly recommend Kalos Health. If you’re on the fence, definitely give it a try, you won’t regret it!

Palak G.

Harsh's commitment to every client's fitness and overall health is quite remarkable. He brings his expertise from Meta and Equinox and combines it with his astute understanding of health and data science from his training at Harvard to make this an unparalleled experience for optimizing training performance. Would highly recommend.

Rana B.

super informative session at Kalos! learned a ton about my body and found out that im not fully recovered from a shoulder injury last year. super knowledgable team about what tk actually do next based off my results! highly recommend!

Benjamin N.

I've been working with Kalos for the past month and have seen great results!! Setting up the scans was super easy, and Harsh has been incredibly responsive and will tailor the plan to your personal needs and goals

Alex K.

Workouts and diets never seemed to work for me and I didn’t know why. Tried Kalos, got a personalized plan and already down 15lbs! Give it a try and don’t give up yall!

Raymond Q.

Incredibly thoughtful and personalized approach to physical fitness. Harsh is a skilled listener and trainer. If you are looking to truly understand your body and what it reacts to, get a dexa scan baseline and training schedule with Kalos.

Alex M.

Extremely helpful to understand the science and data behind your body composition! The team there takes their time to create a custom plan to help guide towards a healthier lifestyle and achieve your goals whether it’s to put on muscle or cut fat. The service and detail is second to none.

Sachin S.

Former high level athlete here. This is better coaching that I had back when I represented my country. 🔥 It's much more motivating to do sports when you can measure the result on your body, which makes DEXA scans awesome. But those scans are nothing without great coaches to make sense of them and plan accordingly, which is where the Kalos team truly shines. I'm already recommending it to my partner and friends.

Gu R.

It's really incredible to get this feedback after so many years of not really knowing what my body is doing. This scan, the analysis and these workouts are so targeted to me I can feel lit. And I love my check in's with Harsh in their studio. So fun. Thank you so much!!

Lauren C.

Dream come true. Love working with Harsh, the heavy lifts, Dexa Scan and pointers on nutrition. Would highly recommend! Learned a lot in just 4 weeks.

Jon M.

Kalos is phenomenal, the program is highly personalized and a unique data-driven approach to health. I haven’t seen any similar programs as focused on data and rigorous scientific analysis as this one.

Conor B.

Harsh is incredibly knowledgeable and friendly! The initial session we had was fast, efficient, and loaded with information. Harsh took the time to understand my current routine and tailored a plan specifically for me. I cant wait to continue the journey with his guidance!

Kevin

Harsh is able to give such targeted and useful feedback on my body and needs through this innovative program that combines a data-driven approach with personalized fitness goals. The DEXA scan was super cool! I've never had something like that done before.

Kat V.

Harsh is great, very data driven, not your typical coach and will get you into a good spot through data, accountability, and building good habits. flexible and understanding of individual needs and caters around it. highly recommend

TJ N.

The staff at Kalos was professional, knowledgeable, and made me feel completely at ease! The personalized training plan they designed based on my DEXA results has been awesome to go through the last couple weeks! I’ve seen noticeable improvements. Highly recommend!

Claudia G.

Last week, I saw Harsh give a presentation and was immediately interested due to his enthusiasm and passion for what he does. I was personally done with exercising and dieting without having a clear goal. The data that the DEXA scan and Harsh's explanation provided have made it clear to me what my body needs and what I need to work on. Incredibly grateful for this consultation! Thanks again, Harsh. Hope to see you soon!

Tessa P.

I did the 8 week program with Harsh and it has been great to track and monitor my progress! Highly recommend for anyone trying to understand their body composition and meaningfully make changes to their health!

Kavin A.

Got my Dexa scan and learned so much about my body and how I can improve my health moving forward! Harsh was super kind and thorough when explaining what each number meant. Would definitely come back to keep tabs on the progression of my health!

Summer K.

Was a little intimidated about doing this but Callum really put me at ease. It was a good lightbulb/aha moment for me to bring more discipline into my fitness routine. appreciated the detailed walkthrough of the scan results and knowing where I stand in terms of lean mass and bone density! Trying the 4 week program and will leave an update here at the end of it! Highly recommend this place for the professionalism and data driven approach towards fitness.

Sahithya B.

Harsh & team have helped re-boot my health; the tailored plan paired with measurable progress reports along the way helps fuel a competitve instinct, while the thoughtful advice helps course correct along the way. Grateful to have them helping guide me towards a healthier state.

RobinB

Very glad to have found Kalos Health. Love the data-driven, results-focused approach to strength training using DEXA scans as the foundation. Harsh has a knack for helping to focus on the essentials and get the most out of every training session. The programming is thoughtfully sequenced and builds progressively - overall, a great health and fitness investment.

Arjun B.

The whole experience exceeded my expectations. Harsh was very patient and thoroughly went over my results and all of my questions. This is an essential service for anyone who is serious about improving their health and making positive changes to their body and health.

Alex S.

Great experience for a first DEXA scan! It was quick and I got a detailed analysis of my body composition, imbalances in muscle mass, and recommendations for how to work towards my goal. Highly recommend for anyone looking to understand their body better!

Sally Z.

Appointment was a breeze and Harsh was incredibly informative throughout the DEXA scan. Harsh has been in the health and wellness industry for quite some time so the value of breaking down your scan results live accompanied by a fitness plan was invaluable. Highly recommend coming here over other scan only alternatives in the city!

Ujjwal T.

great experience. feel like i learned a lot about my body and how to make some changes. i suspect i will sign up for their nutrition/fitness planning in the future because i thought the price was really reasonable for what they were providing. you can tell the owner is smart and passionate about helping you meet your fitness goals…so many people in the health and wellness space lack the medical knowledge to speak about fitness/longevity and i found it refreshing to meet with someone who clearly knew what they were talking about. i definitely plan on recommending them to friends and family.

Asiya A.

I had a great experience at Kalos Health for my DEXA scan. Callum was professional, the process was smooth, and the results were detailed and easy to understand. The scan provided valuable insights into body composition, fat distribution, muscle mass, and bone density, which helped me fine-tune my fitness and nutrition goals. Highly recommend for anyone looking to get a precise health and fitness assessment!

Krishna T.

Fantastic experience getting my Dexa scan! I was pretty shocked at the lack of progress towards my fitness goals over the past few years, and the team at Kalos helped me identify the issues I've been neglecting to address. Ready to kick things into gear with their program.

Terry M.

Had my scan today and was soo impressed with the knowledge this team has!! They walked me through the scan results and gave me pretty immediate things to do to start improving my health based on my results.

Jessie S.

Had my first DEXA scan at Kalos Health today and I’m really impressed! I wasn’t sure what to expect, but the whole experience was smooth and incredibly informative. The staff (Alex) explained everything clearly before we started, which put me at ease. The scan itself was quick and painless - you just lie still for a few minutes. What really stood out was how thorough he was in explaining my results afterward. I learned so much about my body composition, bone density, and overall health metrics that I never would have known otherwise. The facility is clean and modern, and Alex was professional yet friendly. It’s amazing how much detailed information you can get from such a simple, non-invasive test. I feel like I have a much better understanding of my health baseline now. Definitely recommend if you’re curious about your body composition or want to track your fitness progress with real data!

Rhett B.

You get a lot of data with you dexa scan! The scan is much more in depth than the inBody. Matteo knows his stuff!

Jesse U.

I've been a member for a few months now, and Matteo consistently goes above and beyond to ensure that my fitness goals are met. I've seen a huge amount of progress over the last few months and I couldn't have done it without his guidance. Super professional and easy to work with!

Marco M.

Working with Kalos has totally transformed my body and my attitude around my health. I started with a DEXA scan, out of curiosity, and felt urged to try their 4 week intro training sessions. I dedicated a month to really trying to change my body through programmed weight training and healthy eating. Seeing fat loss and muscle gain from just those 4 focused weeks was enough of a taste to commit to long term training and guidance. Having access to monthly scans and data, alongside a dedicated Kalos trainer (shoutout to the incredible Matteo!), has given me the confidence, as a woman, to learn how to lift heavy things and the flexibility to fit these workouts into my schedule, sustainably. Kalos makes it easy to track nutrition and workouts in their app; I can even shuffle exercises or workout days if I need to, which I love. No crazy crash diets, or unsustainable lifestyle changes, just slow and steady progress. I’m now 4 months into my journey and have increased my lean muscle by almost 5%, while maintaining steady fat loss. I’d recommend a DEXA scan with Kalos for general body awareness, but would really recommend their personal training to see how these scans can evolve and inform the changes you want to see. So glad I stopped at that farmers market pop-up all those months ago!

Chloe C.

Kalos health has changed my life. Their data driven approach and personalized coaching tailored to my needs , combined with their kind , caring , and empathetic attitude enabled me to fully recover from an eating disorder ! I was able to fix my unhealthy attitude to food and gain 5!! Pounds of lean muscle over 7 months . I am deeply greatful to their team and inspired to continue my health and fitness journey! Incredible team ! Highly recommend. It was the best money I ever spent because it so improved my health . I am stronger than I had ever been since my 20s and cant wait to continue my journey with their program

Vita M.

KALOS is awesome. I went in a few months ago for a scan and got results that were troubling. I’m a lawyer with too many hours a day to work and without enough time or knowledge to figure out how to fix the unhealthy rut I’d dug myself into. I signed up for training after seeing my results, and am 3 months in. I’ve worked with Matteo and, more recently, Morgan. They are such lovely, encouraging, and helpful individuals. All they ask for is commitment. If you’re someone whose willing to treat the exercises as non-optional, and who is able to follow the very simple and non restrictive nutrition guidelines they give you, you will see results. Kalos can’t do the work for you. But they can give you clear schedules and easy rules that are simple to integrate. They do the work of constructing your plan, you shut off your brain and just do what the program tells you to. When you sign up for the training program, you’ll receive monthly scans that provide you with real information about how your body is responding to exercise and nutrition changes month by month. It’s not cheap, and maybe that’s why it’s so easy to stay consistent: spending real money on these programs makes it pretty impossible to justify cheating yourself. As to whether the price is worth it— I think so. It keeps me consistent. Of course it helps that the team at KALOS have been nothing but curious, honest, kind, and encouraging. They also are willing to help you and answer questions on the app whenever. I’m attaching here just my changes in visceral fat— you’ll see a literal 70% reduction in 3 months. I’ve also increased my lean muscle. I feel better. I can run 45 minutes without stopping. I feel stronger. I’ve got results that support those feelings. 10/10 I’d recommend them. Also shout out to Matteo and Morgan for being so lovely.

Liliana C.

I’ve been working with the Kalos coaches for about a year, and it’s been an incredibly valuable experience. The DEXA scans provide clear, objective insights that help me track changes in my body over time — from muscle growth to fat distribution — and keep me motivated. I meet with my coach monthly to review results and adjust my training and nutrition plan, and the team is always responsive via the app when I have questions. I especially appreciate Kalos’ holistic approach to health and longevity, focusing on sustainable, long-term well-being rather than quick fixes. I’ve been very happy with my results to date and highly recommend Kalos to anyone looking to take the guesswork out of their fitness and nutrition journey.

Nancy H.

I’ve been working out for 20+ years (and some of that time with a trainer). Using the data and insights from KALOS I’m learning so much more about my body / health than I have this entire time. Scheduling has been easy, location is great, and Harsh has been very knowledgeable. Great experience so far! [Update] I’ve now been with KALOS for just over a year and am blown away by the results. I’ve added 7.5 lbs of muscle, dropped 2 lbs of fat, and reduced my VAT by 37%. Since I only weigh 127 lbs, these are huge changes for me. Big thanks to Alex and Harsh for guiding me through this journey!

An L.

Kalos was tabling at an event at the Ferry Building, and I signed up for a deal to get a DEXA Scan. Scheduling was easy, and I was able to reschedule when I wanted to change it closer to a bodybuilding competition I was participating in. Arriving at the location, I was a little surprised to find that it felt like a tiny office space. But I guess all you need is the machine and the table. Alex did the scan and made me feel comfortable. The scanning process took around 6 minutes, and then we sat down to look over results. I had done a DEXA scan two years before and brought in the results to compare. Alex was nice enough to look at both results and provide feedback. It was a very informative, non-pressured experience. I was able to see improvements in my bone density, visceral fat percentage, and overall fat percentage compared to my cohort based on age and ethnicity. If I do another DEXA scan, I would definitely come back.

Dyanna V.

I have worked with Alex and the Kalos team for almost a year and have had a great experience. The constant accountability and creative coaching that they provide has led me to the most positive health mindset and great results in getting my fitness in order. Its definitely no magic wand - you have to put in the work - and Alex has been amazing at guiding me through that journey. The workout programs he builds are thoughtful and varied - the nutrition advice is collaborative and productive. And above all - even when sticking with the program isn't always easy for me - Alex has provided kind but firm guidance on how to make steady, sustainable progress. This coupled with the hard metrics of the Dexa scan make for a great system to get your health where you want to take it!

Matt F.

I’m doing the two-year Kalos program, and it has completely changed my life. Harsh helped me spot the gaps in what I was doing and showed me exactly how to set myself up for real, lasting success. Alex brings so much positivity, encouragement, and attention to detail that my training has leveled up in ways I didn’t expect. I get DEXA scans every two months, and it’s been amazing to watch my muscle go up, my bone density increase from heavy lifting and box jumps, and my lean mass imbalances improve each phase. Once I learned my true maintenance calories, everything clicked—I built muscle during maintenance months and now I’m cutting effectively with real, consistent progress. With Kalos programming and the added support of an in-person trainer for perfect form, I’ve gotten stronger, reshaped my entire physique, and gained more confidence than ever. I absolutely love this program and can’t wait to hit my body fat goal so I can start the athletics phase. Kalos has been one of the best investments I’ve ever made in myself.

Patricia D.

Working with Kalos has been an amazing experience! I’ve had a few scans now, and Matteo has taken the time to walk me through all of the data in a way that’s easy to understand. The entire staff truly knows their stuff. I just wrapped up the 4-week program, which included personalized, actionable workouts and clear nutrition goals. The results were incredible! In just four weeks, I already feel stronger and so much better, thanks to my plan. I highly recommend Kalos to anyone who wants to understand their body better and achieve their fitness goals.

Lauren H.

Just finished my 1 month first experiment comparing results from before the program and after a month doing the program. The results have been already transformative. I've modified my diet and added a weight training program to my existing cardio workout, and I've been able to add 6 pounds of lean mass and lose the same amount in fat. I feel great and most importantly the program the Kalos regiment is sustainable beyond just the first 4 weeks. Morgan has been amazing - adjusting the program for go based in feedback on my results, and working around issues like my tennis elbow and integrating it all. She's responsive on weekends and very easy and fun to work with. Overall a great experience!

Clement W.

My husband and I worked with Josh and Travis at Kalos. We had a great experience both with the scan and the detailed breakdown of our results. This is a great approach to understanding your fitness, and how to protect your health moving forward. I highly recommend Kalos and Josh if you want to improve your health and fitness.

FAQs

Common Questions

Do I have to sign up for coaching?

No. Many people come in for a single scan and that's it. If you want to explore coaching after seeing your results, we'll tell you about it. If you don't, no pressure. Ever.

What happens during a Premium DEXA Scan?

You arrive, change if needed, and lie on the DEXA scanner for about 6 minutes. Then your Kalos analyst sits with you for 20 minutes, walking through your full body composition report: body fat, muscle mass by region, visceral fat, bone density, ALMI percentile, and asymmetries. You leave with a clear understanding of where you stand and what to prioritize.

What can a Kalos analyst tell me that AI can't?

Our guarantee: if you complete a premium scan and don't walk away having learned something AI couldn't have told you, we'll refund your scan. Our analysts combine your DEXA data with your training history, goals, injury background, and lifestyle to give you advice that no algorithm can replicate.

How often should I get a DEXA scan?

One scan shows you where you are. Two scans show you what changed. Three scans show you the full trajectory. For most people, every 4 to 8 weeks is the sweet spot to track meaningful change.

Can I use HSA or FSA to pay?

Yes! All Kalos services are HSA/FSA eligible. You can use your HSA/FSA card directly at checkout to book your scan. If the card doesn’t work, they you can pay with a different card and then request reimbursement.For reimbursement, just request an itemized receipt from us and submit it to your HSA/FSA provider. That should typically be sufficient. If additional verification is required, you can either get a letter of medical necessity from your doctor or through TrueMed — it’s quick and convenient.

What if I want to bring my partner?

The Premium Duo scan is built for couples. You both come at the same time and you’ll each get a full DEXA scan plus a 20-minute interpretation session. It's $69 per person instead of $74, so you save a few dollars and get the same expert guidance.

What should I wear?

Wear comfortable athletic clothing without metal (zippers, underwire, belt buckles). Leggings and a t-shirt work great. We have a changing area if needed.

Where are your locations?

We have three locations across the Bay Area: San Francisco, Palo Alto, and San Jose (Pruneyard). All locations offer the same scan experience with the same analyst-led consultation.
