Metabolism: We’ve all got one, but some people’s are “faster” or “slower” than others’. And that matters, because the rate at which your body burns calories and converts fuel to energy can also affect how easily you gain or lose weight. It also says a lot about how at-risk you are for diabetes, and how much pep you’ve got in your step. While much of your metabolic rate is determined by genetics, age, gender and body size, there are some lifestyle changes that can, quite literally, speed up the process.
It’s important to note that metabolism can’t be solely held responsible for weight gain or loss. Someone with a super-fast burn can’t stay slim eating junk food and not exercising, while people with slower metabolisms aren’t automatically doomed to an overweight fate.
