The metabolic benefits of exercise, muscle mass, and protein intake [1:15:00]
- No one ever says, I wish I had less muscle
“If you want to be metabolically healthy, the best thing you can do is have lots of lean body mass”— Layne Norton
- Muscle/ lean body mass is a metabolic sink
- Obese powerlifters may have some elevations in blood lipids and whatnot, but usually their insulin sensitivity and blood glucose are okay
Benefits of exercise
- Exercise is one of the only things that we know of that without even weight loss improves metabolic health substantially, really substantially
- Layne was on the Rogan podcast a few years ago and made the point that people get caught up in carbs and fat but they’re not even exercising
- This is like stepping over dollars to pick up fractions of pennies
- #1176- Dom D’Agostino & Layne Norton (September 2018)
- A high dose of exercise is not required
- Just going and being sedentary to walking 100 minutes a week, and you will see improvements in health markers
- Layne had his blood work done a while back; he has familial hypercholesterolemia so his LDL tends to run a little high
- People were speculating that he would have really high inflammation because he eats 70-80 grams of sugar a day
- But he’s also getting 60-70 grams of fiber along with that
- His CRP (C-reactive protein) was hardly detectable
- This speaks to the fact that there is a big difference between somebody who is an athlete, training hard, who has a lot of muscle mass, versus somebody who’s sedentary with excess adiposity
- It’s just not even comparable when you talk about food choices and whatnot
“You have a lot more you can get away with, with a lot of muscle mass”— Layne Norton
- Older and frail people don’t think about this [muscle mass]
- People say, “You do all that heavy lifting, you’re going to be in pain when you’re older”
- But you’re going to be in pain when you’re older regardless
- Do you want to be in pain and strong or in pain and weak?
- Peter agrees, when he asks people who have experienced activity and inactivity they will recall being in more discomfort when inactive
“Sitting is to lower back pain what bourbon is to alcoholism”— Peter Attia
- The worst thing you can do is be immobile
