The Mayo Clinic Healthy Weight Pyramid is a tool to help you lose weight or maintain your weight. It focuses on nutritious foods that contain a small number of calories in a large amount of food — such as fruits, vegetables, legumes, poultry, fish or whole grains. Fruits and vegetables, allowed in unlimited amounts, form the foundation of the pyramid. This pyramid also recommends healthy food choices within each food group. Candy and other processed sweets are acceptable, but in moderation — up to 75 calories daily.
