How to Extend Your Life by 10-20 Years
Dying young is an epidemic in the United States …
This is an evidence-based update on what we know about health and longevity, and what you can do now to stay healthier longer. You can find the supplements I recommend below on my stack page, and go to the store page to get the books and other goodies you need. Forget all the small stuff. This is the big stuff that matters, and it’s in order of importance to your longevity.
Summary
Do these 7 things (plus one for women). Everything else is secondary.
Stop smoking
Lose excess fat
Cut sugar and alcohol down to the bare minimum
Start HRT as soon as you have symptoms of menopause
Reduce insulin resistance if your A1c is above 5.6
Reduce and prevent heart disease (get APOb under 90)
Build bone
Build muscle
Smoking
Stop smoking now or die sooner, probably of heart disease. Your choice.
Know your A1c number
If you're even a little overweight, you should read Why We Get Sick, by Ben Bikman. You should know your A1c number, which is a quick measure of insulin resistance. A1c measures how many glucose molecules are stuck to hemoglobin, which gives a running three-month average of your insulin resistance. If that number is 5.7 or higher, you should work on your diet to lower it. Cut sugar, cut alcohol, cut carbs. At 5.6 and below you are insulin sensitive — that is the safe zone, stay in it. Insulin resistance is more likely to kill you than heart disease is.
Here's how I think of it now: Cut sugar and alcohol out of your diet. Don’t drink any calories other than protein shakes. If your A1c is 5.6 or less, you have room to eat pizza, pasta, Mediterranean diet, etc. But if the number goes up over 5.6, you need to reduce carb intake. Two very similar looking people, or husband and wife, will have completely different metabolic reactions to the same diet, so one diet does not work for everyone. If you’re above 5.8 and overweight, you should probably be on a ketogenic diet and stay in ketosis until your A1c and weight go down to normal levels. Just because you're an athlete doesn't mean you should be on a high-carb diet — your A1c number will tell you that. Measure your A1c every 6 months if you aren't 5.6 or below. Use a glucose-tolerance test if you need better data.
Be aware of starches that are high in amylopectin. I have a separate article on amylopectin and gluten.
If you're in the safe zone, you can easily consume small amounts of foods containing sugar, but the goal is not to overdo it at one time, so your A1c doesn’t go back up. Sweets should be seen as a once-or-twice-a-month treat. If your A1c is 5.5, you can have waffles and ice cream if you want, but keep an eye on your A1c and adjust as necessary. If you’re a sports competitor with very low body fat, training and competing often, by all means get your goo and your sports drinks to support your training.
You should always be aware of your A1c, because the “skinny fat” condition — where you look healthy but have visceral fat around your organs — is a killer. If your A1c is 5.7 or higher, you need to take action.
Fat
When you gain weight, you create new fat cells. When you lose weight, you do NOT lose fat cells. Any fat cells you make will be with you forever. If you lose fat, those cells will want the fat back. This helps bears but is hard on humans. Fat cells are like balloons that are ready to fill up quickly but empty out slowly. Help your kids by not letting them get fat in the first place. If you are ten pounds overweight, that should be a red flag that things are going in the wrong direction.
Losing fat isn't that hard, just reduce your calories. Keeping fat off is hard, and most people don't succeed. If you built up 30 extra pounds over 30 years, it's not going to magically melt away in 6 months and never come back. Losing weight is about 30 percent of the job; keeping it off is 70 percent. Diet and exercise are tools - use them intelligently. If you are constantly losing and gaining fat, get outside help.

Hormone replacement therapy
I’m surprised at the number of women I talk with who are not on HRT. HRT is so beneficial to so many women, I recommend it for all my clients, and I have a partner doctor you can use to order everything online. Here's a video conversation with my client Kathleen on this topic.
For men, it's more complicated. Taking testosterone has benefits, but the body compensates, so the benefits can reverse and cause problems later (it also completely shuts down your body’s natural ability to make testosterone). Yet testosterone replacement therapy can be done right and is beneficial for some men.
Women should have a good reason not to go on HRT, while men should have a good reason to start TRT. In both cases, watch carefully for any unwanted side effects and adjust accordingly. If you need a good doctor for this, ask me in our discovery call.
Get enough protein
The older we get, the more protein we need. You should be trying to get 1 gram of protein for every pound of lean-mass bodyweight daily. It's not easy. Aim for about 40-70 grams of protein per meal, depending on your body weight. I’m a believer in protein shakes that aren’t too sweet. They give you a quick 30 grams of protein. I prefer Rockin’ Protein Builder from Shamrock Farms, which has whey protein. Or get protein powder and make your own. Especially good after a hard workout.
I don't have time to go into all of it, but you'll find a lot more on the site on this topic, especially the videos.
What's up with LDL cholesterol?
The evidence connecting LDL cholesterol with heart attacks and stroke is very mixed. I hope to have a thorough update on this topic at some point. But what to do about it is quite straightforward. We know that soft plaque is far more dangerous than hard plaque. You can undo it by reducing insulin resistance and hard exercise.
Should you take statins?
I think most people will benefit from taking statins. Few people have side effects (if you do, stop taking them or switch the kind of statin). And the lowest dose is generally best. If you're on 20 mg, ask your doctor about going to 10. If you're on 40, ask about going to 20. If you don't like the idea, try red rice yeast, it's pretty much the same.
Build bone
If you're not building bone, you're losing it. You can't build bone by walking and doing yoga. Runners and cyclists, even mountain bikers, don't have strong hips and spines. Everyone over 70 has a 25% risk of a fall each year, and 50 percent of falls result in a permanent reduction in the quality of life, leading to death. You build bone through resistance and impact training. Read The Osteoporosis Breakthrough to understand the basics. Resistance is pushing or carrying heavy weight, and impact is jumping and landing fairly hard. Two people in the world have an advanced bone-building program, and I’m one of them. I'll make a better video, but for now you can watch my very blurry video that goes into some of this.
Build muscle
I’m a big fan of Peter Attia’s, and I want everyone to read his book, Outlive. He talks about the value of zone-2 exercise, which I agree with. Zone 2 is a pace that is hard but sustainable for at least a few hours. It’s faster than normal-pace walking, it’s like very fast walking at about 3 miles an hour. You should do that or its equivalent once or twice a week. But I can't emphasize the value of zone-3 and zone-4 exercise enough, even if you're in your 80s. This means going as hard as you can for 2-4 minutes in the pool, on the track, rowing machine, or even jumping up and down in your living room (YouTube videos are great for this). Hard. Like you can't do any more, and the last 30 seconds are very very challenging, and it takes several minutes to recover.
Use a stopwatch. If you ride a bike, pick a hill and always start at the same place and measure your time to the top, then keep trying to beat that time. In the pool or on a machine, it's easy. Always keep trying to beat your previous best time. I also like 2-4km of rowing - how fast can I row 4km at the hardest setting?
Try ten flights of stairs (17 steps per flight is normal in a modern building) in under 90 seconds — without touching the handrails at all. Never touch handrails when doing stairs. Stairs are great, because you know exactly how far you're going, you can do them in any weather, all you need is a building with 10 floors. I'm 65. My record for ten flights is 70 seconds, but that's because I carry 50 pounds on my back up 13 flights three times a week. Can you beat me? If you're older or not as strong, adjust but still push.
Zone 4 is maximum output, like sprinting 100 meters as fast as you can. I'm sprinting 100m in 21 seconds; my goal is under 20. What's yours?
Whatever you do, establish your best time and keep trying to beat it. Do this for the rest of your life. A breath trainer will help.
Don’t forget lifting heavy in the gym, using free weights, and rucking. If you’re not rucking, you should consider adding it to your routine. People who do a lot of walking, Pilates, and yoga don’t live longer than the rest of us. It’s the weightlifters and serious pushers who outlast everyone else. The average 70-year-old farmer will probably outlive the average 70-year-old citydweller by ten years or so.
Don’t get injured
It’s very important not to get hurt, and that’s why you want a longevity coach, not a gym trainer. You need to prevent injuries. The older we get, the longer it takes to recover. It’s much better to avoid injury in the first place. A few of us know how to do this — to keep you under your injury threshold yet still performing at the highest capacity that your system will allow. It starts gently but progresses, because stressing your bones, muscles, and heart will let you do more and more aggressive and agile movements over time, and that is the best way to stay strong and healthy as you age.
What? You have pre-existing conditions? We all have pre-existing conditions. We work with what we have, we strengthen what we can, and we find ways to move forward. I don’t want to make you into a prize fighter. I want to make you leaner, stronger, and more resilient than you are today. The only person you’re up against is yourself.

Creatine
Creatine is a compound made from three amino acids that people think of as a bodybuilder supplement, but more and more research shows that creative a) is very safe, and b) has many other benefits, including brain health and even MS. It helps improve recovery time after exercise. The new recommended dose is ten grams per day. This video is a good overview, and the brand I recommend is on the stack page.
Calcium
Calcium is a critical mineral for bone building. The brand I like is called AlgaeCal Plus. It's similar to getting your calcium from food. It includes magnesium, vitamin D and vitamin K. I think everyone over 40 should be taking it. Possibly everyone under 40 as well. And no, taking calcium has nothing to do with calcium build-up in your arteries, it is not bad for your cardiovascular system, so start taking AlgaeCal Plus today (I’m not affiliated with the company).
Vitamin D
Evidence is now stacking up that too much vitamin D is a bad thing, and most people who get outside don't need to take a supplement. People over 50 should NOT be taking extra vitamin D above the 800 units they get in AlgaeCal Plus. People over 70 who live in temperate zones may need a bit more if they aren't outside often. Stop taking your 2,000-unit vitamin D pills!
Collagen
If you have any joint pain at all, you should be taking collagen daily. See my stack page for details.
Fasting
Fasting is a bad way to lose weight, because you lose muscle as well, and muscle is hard to build back, while the fat comes back readily. Don't fast more than 24 hours.
Fructose
No fructose. Fructose is bad for humans. It goes straight to your liver and activates an insulin response. The only time you should get fructose is in whole fruit. A small amount of juice is okay, and realize most juice these days has sucrose (table sugar) added, which is only half fructose. I drink lemonade watered down 2:1, but I would not drink an entire glass of fresh apple, grape, or pomegranate juice, because it has too much fructose. Anything with high-fructose corn syrup is out.
Processed foods
Processed foods like baked goods, frozen meals, fast food, processed meats, and food made in a factory has ingredients that will cause disease. Even the flour they use in factories is very different from the flour used in your local bakery. Make food at home with single ingredients and nothing processed. Deep-fried foods are bad for you — eat them once a month not once a week, even if you make them at home.
Alcohol
The healthiest amount of alcohol is zero. If you really enjoy alcohol, drop all your junk drinking. That should be 50-70 percent of drinking you can simply give up and the quality of your life hardly changes. It’s easy to do and — assuming you don’t get hit by a bus later — will help you live longer. If you are planning to get hit by a bus, by all means enjoy your wine now!
What about GLP-1 agonists?
Everyone is getting injections, and many doctors are now on Ozempic/Wegovy to lose weight and keep it off. Yet 70 percent are off the drugs within two years, and most of them are worse off. This is not going to turn out well. GLP-1 agonists force starvation. They have many other “benefits,” but the costs to your metabolic system are too high. They probably are a net-benefit to a small percentage of people who can afford to stay on them. Forget fads and medicines. Eat appropriately and exercise harder. If this guy can do it, you can do it.
Sleep
Do whatever it takes to get 7+ hours of sleep a night. Black out your windows. Drop the temperature. Create a routine that works. Measure your cycles using an app or a ring. Find patterns that give you good sleep. One suggestion: make your room as cold as you can possibly get it, like you're winter camping. When you're cold, you snuggle in and don't move around. When it's hot, you move and wake up more often. Drugs as a last resort, but you could look into patches.
Kidney stones
If you've ever seen a scanning electron microphotograph of a kidney stone, you understand why you don't want one. First, drink plenty of water. Second, know your foods that have oxalic acid (spinach, almonds, almond milk, beets, beet greens, rhubarb, Swiss chard, sweet potatoes, chocolate, cocoa powder, black tea, navy beans, soybeans, raspberries) and eat them WITH calcium, so the calcium binds to the oxalate in the gut and gets taken out that way. What causes stones is when oxalates go to your kidneys and then bind with calcium there.
This is the dashboard I use for my clients:
Have I left anything out?
Yes, I've left a lot out. I could write much more about getting the big stuff right and forgetting about all the current supplements, vitamins, drips, green powders, treatments, fake experts, and YouTube influencers. I work with clients around the world to lose fat, build bone and muscle, and add 10-20 years to their lives. Every one of my clients has pre-existing conditions. I always design a custom protocol for each person. This is just an overview.
Summary
Do all these things. If you can do it all on your own, use the resources on this site and do it yourself. But all the pros have coaches for a reason — investing in a coach pays off 100 to 1.

Andy in 2006
You can do this!
Andy Katchmar, age 79
I began my journey at the age of 64. At that time I weighed around 205. I had several health issues at the beginning, but I persevered and worked towards gaining my health back . The first months were for losing weight mainly. Once I achieved 175, I was better able to handle machines and weights. My weight was a concern since I am only 5’ 5” tall. With the guidance of a personal trainer, I made steady advances. After a year, I was in good shape. I have continued on my own for 15 years now. I am still improving as I age.
Andy today, age 79
Althea Boulware, age 57
When I was 46, I started perimenopause and it seemed like no matter what I did, working out 7 days a week and having a pretty good nutrition regimen, my body had a mind of its own. It was not until I started a structured workout regimen, incorporating drop sets, progression sets, tempo training, time based workouts and just sitting in my discomfort, is when my body started to change. I also researched nutrition and what foods were beneficial for me and which foods I should be wary of. My body started to respond. At 57 I've never felt better.
Geoff Keller, 74
I used to be the king of junk food. I never saw the inside of a gym until age 50. Now my workout program consists of a single, two-hour, no-nonsense resistance training session every four days, as well as three, 40 to 60-minute cardio workouts on a stationary bike weekly. I am in my seventh year of being a whole-foods, plant-based vegan.
Kathleen Donovan, age 60
Fitness has always been a huge part of my life. I’ve always been active, participating in sports in elementary through high school. Continued exercising in college and began weight training. Really got into more heavy weight training over the past 15 years. Love the mental and physical aspects. Truly has been my fountain of youth!

Frequently asked questions
What happens during the onboarding session?
You tell me about your health and history. I fill out a form to help you track your progress. Together, we come up with a plan to get started, which will involve some weight training, some cardio exercise, some supplements, and possibly changes to your diet and daily routines. We’ll be working on this for the next eight weeks. By the time the eight weeks are over, you should have a solid foundation for building your future self. Be sure to bring any health records you have to this meeting.
I want to ask a question before I buy
Schedule your discovery call right now!
Will you work with me if I’m seriously overweight?
Possibly. My approach is to work on losing the weight first, which means getting very serious about long-term weight loss. I encourage obese people to look into getting some kind of surgery to get started. Surgery has been shown to be highly effective.
I’ve tried to quit smoking many times and haven’t been able to. Can you help me?
I’m afraid I can’t. You’ll have to find someone else to help you do that. It’s the most important thing you can do. In fact, if you find an amazing program, let me know so I can tell others.
I have pre-existing conditions. I’m afraid I might not be able to commit.
We all have pre-existing conditions! Even more reason to get seriously strong and stay ahead of your doctors for the years ahead.
Do you subscribe to everything Attia recommends?
Mostly, but that’s because he’s skeptical of all the magic molecules everyone is touting these days. He’s very open minded. He’s willing to look at new evidence and change his opinion. I’m coming around to his protein recommendations (you need more protein as you age). I think he’s right about alcohol (zero is best), and I think he’s right about diet. I like that he changed his mind about caloric restriction. I like that he thinks we’re still mostly guessing and have a lot more to learn. He knows humans aren’t mice. I think he makes the best educated guesses.
Are there experts you don’t like?
Yes. I think David Sinclair lives in a world of mouse and worm studies and fake metrics. Whatever he says extends life I would generally stay away from. Peter Diamandis is usually wrong. Most “functional medicine” claims are nonsense. Walter Willett (Harvard) and the “Mediterranean diet” is mostly a collection of weak evidence for various different products, mostly promoted by companies for profit. How much do we really know about diet? Not much. Don’t read a book like “The China Study” and think you’ve just learned anything about diet.
Are there other experts you like?
I’m a big fan of Gary Taubes, which is how I heard about Peter back in about 2012 or so. His books have been very influential on me. He showed that calories-in/calories-out (the metabolic model) is not a helpful framework for people trying to lose weight. He also showed that saturated fat is not bad and doesn’t cause heart disease. He showed that dietary cholesterol has nothing to do with serum cholesterol. I like Aubrey de Grey as a researcher. I like Daniel Lieberman, he says reasonable things in general. For osteoporosis, I like Dr Doug Lucas. See the books page for more.
Are there other experts you stay away from?
Not that these people are wrong, I simply think they are off in the noise: Andrew Huberman, Bryan Johnson, Valter Longo, and anyone who touts the latest and greatest molecule, probiotic, anti-aging pill, or diet. A few of Huberman’s podcasts are worthwhile, but most are skippable. Anyone who recommends more heavy exercise over worrying about diet is on the right track.
Why don’t you talk about many things Attia writes about?
He talks about a lot of very esoteric research. It’s confusing to most people. I think we can choose about 20 percent of his recommendations and get 80 percent of his results — and he says that himself. If a client has those 20 percent really working, we can start looking at the second-order options. For example, I don’t think anti-oxidants are meaningful for human health. They might be, but they are not a front-line approach to longevity, and most other prescription drugs aren’t, either.
What’s your view on osteoporosis?
I broke the head of my left femur at age 51 (ice skating) and my right femur at age 53 (running). That’s a diagnosis of osteoporosis. I’m very skeptical of osteoporosis drugs — I think the cure is worse than the disease, especially if you take bone-building seriously. There are many interesting drugs in development, I try to keep up with the research. I think the best thing is to get calcium from food and stress your bones often. I’m interested in vibration therapy. I think if you have the money to buy a good vibration plate, you should. There are two main kinds of vibration plates, and the cheap $200 plates on Amazon are terrible. There are vibration plates listed in the store here.
Which supplements do you recommend?
See my stack page.
What about rapamycin?
Not a first-order modality. Not second-order either.
What about cold plunges, red light, early light, saunas, chiropractors, metformin, rapamycin, resveratrol, MNM, Klotho, and all the other things various doctors recommend now?
Noise. For some of these, that may change. For now, build bones and muscle in the gym.
What are your dietary guidelines?
See this page.
Do you want your clients to become vegan?
Absolutely not. I don’t pay much attention to diet.
