Role of deranged appetite control system.
It has been recently discovered that certain areas of the brain actually
control a person's appetite and satiety (satisfaction of eating). These
areas do not function properly without sufficient muscle exercise. At very
low levels of activity, appetite does not decline sufficiently and you tend
to consume more calories than you burn.
When the body's muscular system is being exercised properly, the brain
regulates your intake of food in a balanced manner, so that your body
consumes just the right amount of calories.
