if calories in > calories out = weight gain, then what does metabolism have to do with anything?

Question

How does someone’s metabolism impact the calories consumed vs calories burned equation?

In: Biology

Answer 1

Because metabolism equals how many calories you burn each day so if your metabolism burns 4000/day and mine burns 2000/day, but we eat the same 2000 each day. One of us is going to burn a lot of fat.
