Definition: Your metabolism refers to a complex series of chemical processes that convert food into energy as well as establishing the rate at which your body burns calories. Ultimately, your metabolism is responsible for how quickly or easily you gain and lose weight.
We all have a different metabolism based on a number of factors, some we can control and others we can't. Your age, gender, body fat and genes all work together to determine your metabolism. There are ways to rev up your metabolism including cardio and strength training exercise, as well as eating healthy snacks and meals more frequently throughout the day.
