Some people blame their weight on how their body breaks down food into energy, also known as metabolism. They think their metabolism is too slow. But is that really the cause? If so, is it possible to speed up the process?

It's true that the rate at which the body breaks down food is linked to weight. But a slow metabolism isn't usually the cause of weight gain.

Metabolism does help decide how much energy a body needs. But weight depends on how much a person eats and drinks combined with physical activity.
