what is metabolizm

I think it is the rate at which food is absorbed into your body. Could be wrong :) but I think it might be that

What does it change? If you have a high metabolism it will help you lose weight, yes. Exercising boosts your metabolism.

I meant what dus it change so if you have high metabolism you will have a slimmer stumach other than someone with low hu will have a fat stumach ?

Metabolism is the speed of how your body digests the food in your stomach, I don’t understand what you mean why “what does it help do”. If someone has a high metabolism (usually people who eat healthy and stay active) it means food doesn’t stay in their stomach very long, and if someone has a low metabolism it means food sits in their stomach a while before digesting.

:PShows how much I dont know about that sort of stuff :)

It’s how fast your body digests food.
