What factors can in influence a person metabolic rate?

A person's metabolic rate is influenced by several factors, including age, gender, body composition, and genetic predisposition. Muscle mass plays a significant role, as muscle tissue burns more calories at rest compared to fat tissue. Additionally, hormonal levels, physical activity, and dietary habits can also affect metabolic rate, with higher activity levels and certain foods boosting metabolism. Environmental factors, such as temperature and altitude, may also have an impact.
