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

A more active metabolism means the calories consumed don’t go as far to power the body as they are converted to energy and used up and then without more calories, the body starts burning its fat reserves instead = weight loss.

Conversely, a slower metabolism means the calories consumed still haven’t been fully processed by the time more calories are being taken in, so those newer calories are stored as fat = weight gain.
