To gain weight you need to combine protein foods with starchy carbohydrates as indicated below. Good weight gaining combinations are bread, cereals, pasta, rice, potatoes or sweet potatoes combined with meat, poultry, eggs, cheese, nuts or sea food. Peanut butter sandwiches and cheese sandwiches are good weight gaining combinations. The protein in the above combinations will help to gain extra muscles.
