I started playing basketball again at 41. Immediately got Achilles tendinitis. Started dropping collagen in my coffee every morning and cooking with bone broth. Still playing ball, lifting, super active and zero tendinitis. Collagen supplements work.

First book I read in my health journey 14 years ago was Primal Blueprint. That helped me a lot. Now I’m 51 and still thriving, especially compared to all my buddies with beer guts. 😂

LOVE that you are addressing age related topics! There are alot of us older folks out there who are very interested in staying well. Thank you!!! ❤

Carnivore diet for four months. 71 yoa, lost 30lbs, off BP meds with BP average 120/75, all arthritis pain gone, mentally in a much better place with tons of energy. Non-diabetic reactive hypoglycemia gone, blood glucose is now normal with hA1C down to 5.3 from pre-diabetic. Fasting insulin is down to 7 from close to 15. I've never felt better to the point I am now doing five 20 second wind sprints 2-3 times per week plus using weights at home.

Great to see people over 50/60 being given the air time to share their experiences. After all, (we) have had more time through our journey's to experiment with all kinds of nutritional and hydration options. Yet we are often over looked by the "younger" community as they think they know best. I learnt all of my great balanced eating habits from my 90 year old grandfather.

2 meals a day made us healthier and saved us a lot of money! Love these interviews!!!!

Mark got me started on eating, and exercising right. This was over a decade ago. Thanks to both of you for your path finding. Both of you guys have helped me, and many others. Again, thank you both.

This was a great interview! Thank you Thomas for addressing the issues we older folks face with our fitness levels. I am a 70 year old weightlifter, and fitness nut, and he is right about listening to your own body. I normally would train every other day, but now I notice I need an extra day. On those off days I have bought a rebounder and I will do a 15 min workout, carefully, and I love it. It’s fun!! I walk the beach every morning because it’s fun!! I am playing racket ball, with myself, after my weight workout just because it feels so good. It’s all about having fun now, and why not!!! AND I whole heartedly agree that stretching is an important component to add as you age!! ❤

Collagen is 💯. My right hip and hubby’s left shoulder dodged the surgeon’s knife. We decided to take collagen BEFORE going in for the recommended surgical procedures. Within 2 months of taking 20-30 grams collagen daily (both of us) pain reduced 90%. In 7 months we were 100%. What the imaging scans look like now, we don’t know, but for now we are soooo good🙂🙏🏽

Carnivore adjacent. Exactly what I am. Mark is the OG. I read his book primal blueprint 7 years ago. Still has an impact on me to this today. Mark’s not afraid to change his mind on things. Rare breed. Mark for president.

Then I think about George Burns who died at 100 years old. His recipe for long life was be around positive people, don't stress or worry. He walked everywhere and had a very positive mind set. Oh yes, always loved his cigars right up to his death. But he enjoyed his life. I think that is key, enjoy, relax and live one day at a time.

Mark was such an influence on my health... he started me on the path to Paleo so many moons ago, made a huge difference on my health... That was a great interview! Thanks

Mark, you got me started many, many years ago - about 15 years I think - can’t thank you enough. You have so much common sense. Thanks for all you’ve done and shared and thanks to Thomas for this interview. Excellent.

I don't take advice from Marketing Pros like Sisson, Saladino and Dave Asprey. They just switch back & forth between whatever they need to sell/ re-sell and revamp their product lines, books and gain attention for their own promotion. ALL Of these guys were PRO Saturated Fat like CRAZY about 5 years ago. Now it's all "I don't seek out Sat Fat" and "fruits are healthy".

Great info Thomas. Love learning from Sisson as he learns and grows. I really appreciate the direction of your channel, Thomas. Love that you are curious with an open mind. Keep up the great work!

That was an excellent interview with Mark. Lots of logical wisdom on health and nutrition particularly for those over 60.

I warned Thomas DeLauer years ago, that if he continued to bulk up his bi's and tri's, there would come a day when his arms made his head look small. That day has come.

Excellent talk you guys, really enjoyed it. Thanks Thomas, and thank you Mark. You both are inspiring to listen to.

i been doing carnivore diet for 5 years now, best thing i ever did, hard to sell supplements to people on keto/carnivore diet , i assume this is why fitness influencers are jumping ship from keto/carnivore

Another great video! Mark Sisson ... get your hip replaced and have your mobility back to 100%. The very best thing I've done for myself, now 74yo, had both replaced almost ten years ago. LIFE CHANGING!

Just excellent information, guys, thank you so much! I’m 60, and keen to make adjustments so I eat and workout optimally, but without the intensity I might have once had (ie - my motivation is mainly about what’s practically achievable at my age - while still being at my best). In that sense this video is incredibly helpful 🙏

I'm 65 and what works best for me is no more than 2 meals a day, no eating at night. My first meal is higher fat and protein to curb cravings during the day. But my later meal may have some carbs (they make me tired so I wait until I'm not as active). I do biking, walking, swimming (500 meters per day). Will be adding weight training again soon (summer camping threw me off). On this very doable routine I've been able to maintain a steady weight of plus/minus 140 lbs (at 5'11"). My energy is good and I don't look my age.

Thanks guys! Superb conversation and information!!!

Tom, really enjoy your last couple videos with the interviews. I know you the answers to your questions but like how you let the guest provide their insights. Appreciate the content and format. Have learned a lot from your videos. Keep up the great work.

Mark is the best! Thanks for this interview. Keep up the good work, Thom!

Mark is a breath of fresh air listening to him speak about his lifestyle of balance and fun. I heard him on another podcast talk about his interest in ultimate frisbee and he seems to be most interested in finding joy in his lifestyle which is admirable.

Awesome educational material! THANK YOU very much Thomas and Mark.

The image quality of this podcast is amazing such detail 👌, I am 63yr & what Mark says about getting tight I can agree ,I always feel like I need to do more stretching 🙂

When I was in my 20s, I forced myself to drink. I stopped doing that, because it made me get up to pee 4-5x per night. Now I only drink when I am thirsty. I stopped forcing myself to eat breakfast, and only eat when I am hungry. These changes have liberated me in all kinds of ways. When I ate 3 meals a day, I got hangry. Intermediate fasting/eating when I am hungry has gotten rid of those hangry episodes.

Love this kind of interviews, thank you for this retro, really valuable information 💕

Agree 💯regarding the use of collagen in terms of healing injuries. I had a knee issue that many would have said needed surgery but I was able to see it get better with the use of collagen peptides (and prayer)

I'm 72 and eat and think much like Mark, thanks for confirming I am doing some things right. I got a dog that forces me to walk twice a day, briskly for and hour early morning and an hour in the afternoon. This has really changed my life especially my leg muscles. I even do some sprinting which not that long ago I never thought I would be able to do again. I stay mostly Keto but eat healthy starches like Kabocha and sweet potato, natto. I do not each much greens due to the pesticides they bring although in summer I enjoy a salad daily of avocado, tomato, cucumber and tofu. I feel great!

At 82 I have been a Naturopathic doctor for 50 years. I was educated in the Natural Hygiene movement: Dr Shelton, Isaac Jennings, John Tilden etc. The mixed diet ( basically Mediterranean) has worked well for me, with emphasis on vegetables and fruits, but some meat and fish, but not overdoing the protein. Dr Longo says seniors crave more protein, maybe because of less efficient assimilation. I've never been an athlete but for the last 5 years or so I have been following a modified Mike Mentzer lifting routine, which emphasizes long recovery time. The thing is to get lean. I'm happy to see some actual gains. I really think it's important to modulate animal protein intake. Those big molecules can be a burden to the kidneys. I enjoyed the interview

Way to go Thomas! Excellent conversation. Always appreciate Mark Sisson…even more so now that I’m older also. 😀

I always enjoy your interviews with Mark Sisson! He always has interesting insights on the health community and makes great products under his Primal Kitchen brand that I buy. I agree that fats should not be seen as bad. Low fat, high sugar, and high starch diet have only increased obesity since the 70s.

I really enjoy hearing from Mark, his wisdom is refreshing! Love it

A gelatin dessert made with grass fed beef gelatin and fruity herbal tea. No sweetener required. 11 grams protein in 1 tablespoon dissolved in. 75 cups tea. Jells beautifully and tastes great.

Sisson is awesome watched him on other interviews. thank you Thomas. watch you each day

Hi Mark, Don’t fear hip replacement surgery. I endured unbearable pain for 2 years and became almost totally inactive. Had robotic surgery in NYU Langone and walking the next morning with minimal discomfort. I was back to work after 3 weeks, and by 5 weeks I was on stationary bike, swimming and taking 1 mile walks. I now have full range of motion too.

This man is a breath of fresh air on the fitness scene because he is not overdoing anything. I especially love his position on hydration and not overthinking stuff.

I always appreciate these interviews with Mark, his advice is great because he's the proof of a healthy lifestyle.

So glad of this dialogue.. thanks!

I had sten cell injections in my hips back in 2016 (from my fat and bone marrow). Took pain away for 4+ years. I could have tried them again rather than get replacements but it is just so expensive and I had the insurance to do replacements for almost nothing - so I went that route almost 2 years ago. Unfortunately money makes it prohibitive for most people. Replacements were a long recovery but took away the pain.

He's been on my mind a lot lately, even though I haven't seen him around for several years

I am late 40s. Primarily workout with my home kettlebells, dip station, and pull up bar. I agree about not needing as many calories. I was an Army Officer and retired last year, The high tempo while active duty has changed. I would get up at 0400 and go until late and work also was intense and I needed fuel. I still work, but much less intense. I just don't need that much food anymore.

Woohoo! Great interview! Nice to see a guest who's older than I am and can speak to the things those of us 65 and older experience.

Excellent as always Thomas. Great interview! Mark, you look amazing at 70!

Great interview. I appreciate Mark Sisson’s decision to hold off on the hip replacement surgery, although I’m sure there are times when he just wants relief. Working on his nutrition will definitely help in the event that he changes his mind in the future. Sometimes people think that because modern medicine has become advanced that, they can rely on a surgeon to fix the problem. It doesn’t always work out that way. My father suffered from four different types of cancers over a period of 20 years. He would have a surgery, get chemo and radiation, then go into remission. Then the next cancer would emerge, and he would go through the same cycle. Eventually, he thought he was indestructible. He suffered from a particular type of arthritis most of his life that was genetic for him. So at age 69 he wanted a hip replacement. He found a doctor that would do it. 20 years of cancers, and he passed away from that hip replacement surgery. He was also diabetic. They could not filter his blood enough to keep him from becoming septic. Doctors will collect insurance as long as insurance allows them to. If only he would have changed his diet and nutrition during those 20 years, but he was so dependent on doctors and surgeons coming to his rescue. In my family I have relatives that live to their late 90s. Nutrition is important.

Loved the interview. Huge fan of Marks.

Awesome to hear Mark is still playing ultimate frisbee! 🙌🏼❤️

I started taking collagen/gelatin at age 45, after 8 years of tendinitis and joint pain. I am 51 now and feel like I did in my 30s before I injured myself. I am back to doing calisthenics and gained 15 pounds of muscle from exercise. Before collagen, I felt like I was 85 and had a hard time getting out of a chair, low back pain especially. I also added MSM, ascorbic acid and Mg citrate. This is my morning cocktail, after my morning workout.

All kinds of great. Thanks!

Very interesting interview. You lose your thirst mechanism as you get older, as you lose muscle protein synthesis - ability to uptake protein. Sisson should know this. There are physiological changes as we get older. However, I have learned so much from these two. Sisson has done a great job bringing real health to the forefront.

Brilliant interview!!! Common sense explanations... we tend to over think everything these days.

Great info, thanks

Mike Mentzer knew what he was talking about..I'm 51 and growing like crazy while lifting with my 19 year old son.....please listen to Mike Mentzer and his technique..You won't regret it. ❤

Good video, relates to my current situation ..

He’s great to listen to and makes me think about priorities and values in life. Approaching 40 this is becoming more and more important. Two meals a day are not enough for me to keep muscle mass though 😂

I think Mark Sisson and Bryan Johnson should have a conversation together because Mark uses intuition to be healthy and Bryan wants to use algorithms to be healthy so they have two different ways of thinking with their approach to longevity.

Awesome interview

I love Mark and I was one of the first Primal Blueprint Health Coaches certified in the world. With that being said, as I went further and further into the “Primal” lifestyle it just wasn’t matching up to what I needed to fuel my body on a day to day basis. Having a child will keep you on your feet and moving and low carb was actually causing me to gain weight regardless of energy balance. As I’ve gotten older and my focus has turned more towards longevity, I’ve been research the blue zones and their diet. Paleo is a great framework but I don’t live 2 million years ago I’m living in 2023, the question then becomes what do the longest healthiest living people on the world do today? The answer for me is what I’ve coined a “Paleoterrian” diet where I combine the best of Paleo and Mediterranean. You’ve got to find what works for you and in the context of your life. Kudos to Mark for always being willing to adapt and take a different approach when warranted.

Mark got me into paleo/keto. I'm forever grateful for that.

This is what most people mix up and confused; Exercise for Health vs Exercise for Performance. You shouldn't be exercising for performance unless you're a professional athlete. You're causing more harm and damage to your body than you need to. Dealifting 2-3x your body weight or running for 20km... for what??? Exercise with the effective dose. Excessive and too much are never good and is redundant.

Much respect to this gentleman. I listened to every word he said

Love these great guys! My age is in between, so I understand them both very well😉. Is Mark dry fasting for at least 72 hrs aswell? Grts from The Netherlands🍀

Awesome conversation!

I find the whole reinventing what people should eat, interesting because we lost a lot of what we used to know. But have also gained new insights.

For a collagen supplement, do you @thomas have a recommendation? … or what should I look for in the ingredients

As a 77 year old, this video is a big help...he has echoed my own thoughts....Know I need more collagen!

OK I do make bone broth from Grassfed beef bones. I put organic vegetable stock in instead of water.. any suggestions on how to improve that nutritional value?? Also, what type of collagen do you suggest? I am particularly interested in collagen that may help my damaged retina in my left eye. a central occlusion seven years ago. I am not blind, but I don’t drive anymore. Any thoughts on how to improve that with some type of collagen, or any other way? Thank you. I think you an amazing researcher. You just pull everything together and unless anybody else up there.

Hello Thomas , can you please look into and make a video about the COMT gene

Thank you I'm 63 and working out and eating has changed. Minimum amount of running and working out with wts.alot has changed throughout my life.

Nice interview

I'm 72 and went whole food plant. Make sure I get a fish pill, turmeric, berries, green tea. It's all about your joints when you get older. Take a walk every day. Light lifting.

I'm a financially obligate carnivore: I can only afford eggs, sardines and ground meat.

Mad respect for Mark. First of all, if I can make it to 70 and be there for my family I will be a happy man, but to make it there in the kind of shape he is in, with the insights that he has is very impressive. Love the content lately.

Hats off to this guy... I' wish I am fit like him when ı'm his age!

Loved this talk. Im 54 now 5'7" female and been doing crossfit for over 15 years. As my body changes with perimenopause, i know that my nutrition needs are changing too, especially with regards to hormonal changes. Im now understanding somewhat reluctantly, that i cant and more importantly go like i used to because metabolically it's now counter productive to recovery and adrenal fatigue and cortisol outcomes. Im eating up the knowledge from these talks and hoping tjat some of it applies to my current status.

I got sick on Paleo because I was eating more veggies than a noodle, pasta, bread based vegetarian. Sally Norton saved my life with her knowledge regarding toxic ( oxalate) plant based diet.

Great common sense thank you I really appreciate your authentic heart.

He’s frickin 70?!?!! He looks amazing!!!!

Primal Blueprint was my first foray into the world of healthy eating 15 years ago. Thankfully I found it young, turning 40 next month and always stayed lean. Thank you Mark.

Really a great interview. Very helpful for me, i do "carnivore adjacent" myself. Greetings from germany.

I’m 78, vegetarian over 50 years…. dropped 20 kgs prior to mcl cancer diagnosis 15 months ago, reluctantly accepted 3 rounds of chemo but I’m sure keto assisted in my keeping cancer at bay… Thx Mark, you are my best educator for sure…. Today’s video showed me the importance of keeping protein up a little, consider collagen supplements and going back to NOT measuring hydration…. You offer the best balanced information…. thank you… My negative Oncologist firmly believes my cancer will return, however at 78 it’s quality of life not quantity…. Btw I have my own outdoor kitchen and have become a fine dining keto chef, that even my wife raves about…. although I might have to add a few more eggs and tofu over the course of a week.

Always a fan of Mark Sissons's experience!

Excellent discussion - I always enjoy listening to varying perspectives on health into old age (I'm 71). I noted a comment about a product having FDA approval - and I would never use that as a benchmark! FDA is a completely bought-and-paid-for agency, and will approve or ban products based on the wishes of their corporate sponsors - and nothing else! In some cases, no amount of petitions or testimonials will sway their decision, even if it's from experienced, licensed practitioners, so I disregard anything they have to say!

I was already going to start having bone broth to try to heal my tendons from Lyme disease, this encouraged me even more.

The code did not work on the chocolate covered nuts.. would you call them and get this fixed. thanks:D

Mark Sisson has been my hero since 2009. Keep moving!😁❤

I'm 62 and I agree, save the flavor of olive oil to drizzle on your veggies. I used to fry all my lean meat in oil until I figured that out. My breakfast these days is ground beef with berries, no fat needed.

As an endurance athlete myself, I have found my recovery and adaptation to training is much better when my protein intake is higher. I aim for 110-120g a day

Great interview. Where did he say he's done with Paleo?

So should I become a fruitarian and supplement with protein powder? Will the fruit cause non-stop spikes in blood sugar? And how would I get enough fiber? One of my concerns with keto and carnivore is Omega-6-ing myself to death with inflammation or going broke buying 100% pastured livestock or wild seafood. Thanks.

Plant based and loving it. I can get longer work outs at the gym

Carnivore is not the only way. I eat carbs from oatmeal, fruit and sweet potatoes. Seems to work for me.

Good material! I agree with most except the standard take on stretching. I used to be a big stretcher but it made me feel horrible; I was always getting injured. Then I discovered Greg Roskopf & MAT & how he demonstrated stretching does weaken muscle tissue. There are white papers on the subject, but Western thought & dogma prevent it from getting any traction in the exercise/health community. At any rate, I don’t passively stretch anymore the past 10 yrs & simply actively stretch, which is nothing more than lightly going through different ROM movements & therapeutic isometrics such as what MAT teaches & my health hasn’t been better.

At 46 (as of today🎉) i find that more moderate workouts, walking, more protein, and frequent smaller meals keep me super fit and energetic. 5'11", 125 lbs.

Great vid.

Remember also, he is taking hormones. Not to suggest that is bad but it is a very big influence on his muscle development.
