Regulation of Appetite and Body Weight

Regulation of appetite and body weight involves a complex interplay of hormones, brain signals, and environmental factors. Hormones like ghrelin (which stimulates hunger) and leptin (which signals fullness) communicate with the brain to influence our eating behaviors. The hypothalamus, a brain area, plays a key role in balancing hunger and energy expenditure. Additionally, lifestyle factors such as diet, physical activity, stress, and sleep can impact how our bodies maintain weight. This regulation helps to ensure our bodies receive the necessary nutrients while preventing excessive weight gain or loss.
