Desirable weight is a very individual thing. It may be described as the weight at which a person both looks and feels his best. Height, bone structure, and muscular development must all be taken into account.

Life is much easier in many ways for people who are not too fat or too thin. They usually feel and look better. They are apt to live longer. They are less likely to suffer from backaches, foot troubles, constant fatigue, and a host of daily discomforts. They have more fun buying clothes. Normal weight is worth any effort it takes to reach and keep—worth it in terms of everyday comfort and of a healthier, longer life.
