Are you looking to kick-start your metabolism? Here are a few tips! 1. Build muscle. Your body always burns calories, even when you’re doing nothing. Your resting metabolic rate is much higher if you have muscle. 2. Keep drinking water. Your body needs water to process calories. If you are even mildly dehydrated, your metabolism may slow down. 3. Power up with protein. Your body burns many more calories digesting protein than it does with carbohydrates. As part of a balanced diet, replacing some carbs with lean, protein-rich foods can boost metabolism at mealtime.
