Eat less food more often. Try spreading your meals throughout the day (instead of three regular, larger meals, eat six smaller ones). Eating more mini-meals combining protein (meat, poultry, dairy, and fish) with produce and fiber-rich complex carbohydrates (whole grains) will help satiate your hunger and boost your energy. Try eating a piece of fruit or vegetable every few hours. Eat more fiber-rich grains, such as oatmeal or whole wheat bread.
I do this, lol...Bruce says I "graze" because I'm constantly munching on oranges, pretzels, mushrooms, whatever!
