Final answer:
Age, gender, and genetics are some factors other than BMR that influence body fatness.
Step-by-step explanation:
Factors other than BMR that influence body fatness include age, gender, and genetics. Age affects body fatness because as we age, our metabolism slows down, which can lead to weight gain. Gender also plays a role, as men generally have higher muscle mass and lower body fat percentage compared to women, resulting in a higher BMR. Additionally, genetics can influence body fatness, as some individuals may have a genetic predisposition to store more fat or have a slower metabolism.
