Eating snacks between meals is a good way to help keep your metabolism running throughout the whole day. Snacking between meals helps us not get too hungry and overeat at the next meal. Eating 1-2 small snacks each day is a good idea (between breakfast and lunch, between lunch and supper, or after dinner). A good snack contains about 100-150 calories, is low-fat, and contains carbohydrates and protein. So, try eating a piece of fruit and some peanut butter, a few crackers and some cheese, or a granola bar with protein in it. Carbohydrates in your snack give immediate energy and protein keeps you full longer.
