Why can't doctors figure out why you're fat and I'm not.?

Question

I've been skinny all my life and my best friend has always been fat. I'm 6'-3" at 147 lbs and my friend is 5'-10" at 298 lbs People always tell me I have a fast metabolism. If that's so why cant doctors make other people have fast ones. Is 'it because it will ruin the billion dollar diet industry that doesn't work.

Answer 1

alot of it is down to genetics read up about body types

You are an ectomorph and your friend is an endomorph thats just the way it is. There are certain things you can eat and do to boost metabolism but there is no one factor or gene that if you turn on will make you burn the energy faster.

Answer 2

Answer 3
