ENERGY NEEDS OF THE BODY: BASAL METABOLISM
The body uses glycogen, simple sugars, fatty acids, glycerol, and amino acids to supply energy. The breakdown of these substances requires numerous steps and ‘is exceedingly complex. The rate of breakdown depends upon the total daily energy requirement: the basal metabolism, the amount of voluntary activity, the influence of food, and the needs for growth.
Basal metabolism, sometimes called the “cost of living,” accounts for more than half of the energy requirements of most people. It includes the involuntary activities of the body (activities over which we have no control) while resting but awake. The breathing, the beating of the heart, the circulation of the blood, the metabolic activities within the cells, the keeping of muscles in good tone, and the maintenance of the body temperature require energy.
For measuring the basal metabolism the following conditions are observed: (1) the individual is awake but lying quietly in a comfortable room; (2) he is in the post-absorptive state; that is, he has had no food for 12 to 16 hours; (3) his body temperature is normal; and (4) he is not tense or emotionally upset.
For his basal metabolism the adult requires about one kilocalorie per kilogram per hour. Thus, a woman weighing 55 kg (121 lb) would have a basal metabolism of approximately 1320 kcal (1 x 55 x 24). A man weighing 70 kg (154 lb) would have a basal metabolism of 1680 kcal (1 x 70 x 24).
Several factors affect the rate of basal metabolism. The first of these is body size. The larger a person is the greater is the amount of lean muscle tissue and the greater is the skin surface area. Thus a tall, well-built man has a greater skin surface and will have a higher basal metabolism than a short, fat man of the same weight.
The amount of muscle tissue has an effect on the basal metabolism. An athlete with firm muscles has a higher rate than a non-athlete with poorly developed, flabby muscles. Usually men have a higher rate than women, because men, as a rule, have more muscle tissue, and women have more deposits of fat.
Rapid growth increases the basal metabolism greatly. Infants in proportion to body size have a very high rate of metabolism. The metabolism is also high during the rapid growth period of adolescence and the last trimester of pregnancy when the fetus is greatly increasing in size.
After the age of 25 years the metabolism declines about 2 per cent for each ten years. Thus, at 65 years the basal metabolism would be about 92 per cent of the metabolism of a young adult. Many men and women become overweight during middle age because they fail to reduce their caloric intake as their metabolism goes down.
The thyroid gland produces thyroxine, an iodine-containing hormone that regulates the rate of energy metabolism. If too much thyroxine is produced, the metabolism will increase; if too little thyroid hormone is manufactured, the metabolism will be correspondingly lower. The level of protein-bound iodine (PBI) in the blood is now widely used by physicians in place of the basal metabolism test to determine the activity of the thyroid.
