Muscle tissue burns 7-10 calories per pound per day. This means someone who gains 100 pounds of muscle (e.g. from 150 lbs untrained to a 250 lbs bodybuilder) would increase their metabolism by 700-1000 calories, almost a 50% increase in the average daily male calorie requirements of around 2000 calories.

That is an insane amount of training - big lifestyle changes! I increased my calorific needs by 1000 a day by doing a 10K run (1hr) before breakfast. Still a 160lb weakling :)

I think thats basically true for most people, hence the belief that metabolism slows with age. Proving that its not metabolism would imply that our weight gain in later life is a combination of other factors. I would bet good money on the increase in sedentary leisure activities, the reliance on motorised vehicles and a lack of energy to be active. I would bet on those long before anything as nebulous as diet or inta…

Have kids and compare yourself against them. It truly sobering to see how much relentless energy hey have, in body and mind (and when they hit the wall with burning out all energy, they hit hard). All the movement is just burning through all energy. I feel myself very active, but next to my 3 year old son I feel glacial and lazy. We can reverse that, like we can revere many ways we slowly decline, just need a right m…

I wouldn’t be surprised if most thin people who claim to eat lots of junk food actually just eat a lot less regular food. In other words, they don’t eat many calories, but the calories they do eat are junk.

This. Plenty of times I've been to lazy to make dinner and ate 200g of chocolate and a coke in a single sitting.

A lot of skinny people have high metabolism, how do you explain that?

Over my life I’ve been close to a small handful of perpetually skinny people who thought they had high metabolisms. In every case, when I watched them closely, I realized they barely ate anything. My ex-gf was one of these people and would routinely tell people about how she could eat anything and not gain weight. But when I would go on a severely calorie-restricted diet I was still eating more than she did on a norm…

That's also completely canceled out by enjoying a single 32oz soda. Walking a lot and having a bad diet rarely even each other out. And it's so easy to cancel it out I don't think most people realize. A brisk 2km walk burns less calories than are consumed when eating two regular Oreos.

Strava tells me I burned 3,3000 calories this morning on my (4 hour)100km bike ride. About the equivalent of drinking 2 cups of melted butter, or eating 50 pounds of lettuce. When I'm doing exercise like that regularly it's hard to eat enough.
