One step at a time

　　Changing eating patterns can be extremely difficult. Food plays so many roles in our lives, and we've formed our eating habits over many years. It may be easier to make one food substitution at a time -- for example, switch from whole milk to skim milk, then eliminate butter from your diet. Once again, gradual progress is the key to successful weight loss and maintenance.

　　Since most Americans eat too much fat and sugar (both of which contribute to weight gain), replacing these with whole grains, fruits, and vegetables should lower your intake of calories and provide rich sources of vitamins and minerals at the same time. Also, protein should come from low-fat sources like fish, beans, chicken, and soy.
