About health

The number of calories used by the body each day to maintain present weight is called the daily caloric need. Part of this is the minimum calories needed to keep the body working.The rest is the number of calories spent in carrying out various work and leisure activities each day. The amount of energy needed to keep the body working is influenced by the body composition,size,and age. Generally,men have a higher minmum caloric need than women because they have more muscle tissue and less fat,and because they are larger.More energy is used when there is more muscle tissue.Energy from food is changed in muscle tissues to energy that can be used by the body,and this process uses energy.A large person,of course,needs more calories to keep the body going than a small person. The influence of age on minimum calories need is usually linked with periods of growth.For instance,caloric needs are greatest during infancy,adolescence,pregnancy,and lactation.As an adult grows older,fewer calories are needed to keep the body working. That’s something about health.Time is limited.
