Hormonal changes can affect body weight by influencing metabolism, appetite, and fat distribution. Hormones such as insulin, leptin, and cortisol play essential roles in regulating hunger and energy balance. For instance, an increase in cortisol due to stress can lead to higher appetite and cravings for unhealthy foods, potentially causing weight gain. Additionally, hormonal fluctuations during menstruation, pregnancy, and menopause can also affect weight and fat distribution. Understanding these hormonal impacts allows individuals to adapt their fitness and nutrition strategies to achieve better weight management and health outcomes.
