Your metabolism burns more calories while you are active then when you are at rest. By lifting weights you build more muscle.
Muscle burns more calories than fat.
Therefore, working out with weights will speed up your metabolism. 2.Eat more often By eating more often you will be spreading your calories between 5 to 6 small meals a day. These calories will be used for energy instead of being stored as fat. The combination of smaller, more frequent meals allows your body to get nutrients when it needs them. When you give the body small doses of energy throughout the day it will use this energy instead of your muscle tissue.
