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

All weight gain boils down to the fact that you are consuming more calories than you are using

Now, where the complicated bits are is that there a million different things affect calories in your body

Your metabolism is the system of chemicals and processes happening all the time that convert the food into energy. Your metabolic rate is influenced by many factors – including age, gender, muscle ratio , amount of physical activity and hormone function etc

So basically if you have an active metabolism, your body is going to processing calories much faster. If you eat the same as someone whose metabolism isn’t as active, you’re going to lose weight faster than they are (or at least not gain it as fast)
