How body composition, hormones and environment impact basal metabolic rates between males and females

What is the main explanation for the difference in basal metabolic rates between males and females of the same body weight?​

Males have a higher percentage of lean body mass

The main explanation for the difference in basal metabolic rates between males and females of the same body weight is due to the differences in body composition and several hormonal, genetic and environmental factors.

Males generally have a larger body size, more muscle mass, and a lower percentage of body fat compared to females of the same body weight. This is due to the effects of sex hormones, particularly testosterone which is known to promote muscle growth and development. Muscle tissue is metabolically more active than fat tissue, and hence males tend to have a higher basal metabolic rate (BMR) than females.

Additionally, other factors such as age, genetics, physical activity level, and diet can also influence metabolic rate. For instance, an individual with a higher proportion of lean muscle tissue or engaged in more physical activity is likely to have a higher BMR. Genetics can also play a role, with some people having a naturally higher or lower metabolism.

Overall, while gender does play a significant role in determining BMR, there are several other factors that also need to be considered when looking at individual differences in metabolic rate.
