I'm documenting every part of the BBC Documentary 'Why are Thin People Not Fat' while I watch it. Don't forget to watch part 1 and part 2!
Wow. It's so awesome to hear a doctor say humans have a biological determined natural weight, that varies from person to person. "Our bodies do their best to maintain that weight: whether it's fat or thin."
That doesn't mean you can't influence your body shape, but your body will constantly try to bring you back to whatever your normal body weight is. And that is different for every person!
Dr. Allison at the University of Alabama at Birmingham says our 'normal' body weight is shaped even before we are born. Factors such as how old your mother was when you were born, and the amount of calories taken during pregnancy play a role.
This video covers week one of the experiment -- boy, what a ridiculous amount of food these folks had to eat...I'd almost feel bad for them! It's super interesting to see big differences in weight gain at the very start of this experiment. Can't wait to see part 4!

One benefit of a small chest is it helps you look skinnier :)
