All of us endurance athletes must be about to die by the "lifetime calorie limit" rule then...

Their hearts beat faster and must pump more blood under higher pressure, and they must also breathe more. Part of the reason they're always gasping for air, besides their own fat choking them, is that they NEED more oxygen, and oxygen oxidizes (duh), so it damages and kills more cells.

Good question. I don't know, maybe there's something about intensive exercise that combats or negates the effects of aging by excess calories. There are a lot of things that happen in your body when you exercise intensively, things like hormone level changes and the like. I'm no scientician, I'm just putting out a theory here.

😄 sorry playing the devils advocate.

Scientician here. People who eat more because they exercise more still produce more reactive oxygen species (ROS) which are implicated in aging and naturally occur during the process of breaking down food. Antioxidants are supposedly good at counteracting these evil molecules. In addition, there are probably benefits to moderate exercise in terms of life span which could possibly cancel out the damage from increased caloric intake (no source, just speculation). That being said, people who live to be 100 are the ones you see walking every day and only eating what they need, so I think that there is a sweet spot between limiting calories and exercising that results in a longer life than being sedentary and restricting calories.

Your body grows new cells when fed. It repairs old cells during states of caloric restriction. The human life expectancy went up during the great depression because of food shortage. Probably also because people were getting chubby even then.
I posted a video that touched on it not too long ago but it got too many rees

This makes sense, as your cells replicate and die each replication brings the chance of a bad mutation (cancer), fats have significantly higher chances of getting cancer.

Hey, that's interesting, never thought of it like that before.

I think it's because being so fat shortens their lifespan so that aging a year in real time is more like 3 years in tubbytime. Like dog years.
