What can be a factor influencing body fat levels other than diet and exercise?

Age and metabolic rate are significant factors influencing body fat levels beyond just diet and exercise. As individuals age, their metabolism naturally slows down, which can lead to changes in body composition. This slowdown can be attributed to a decrease in muscle mass and hormonal changes that often accompany aging. A slower metabolic rate means that the body burns fewer calories at rest, which can contribute to an increase in body fat if energy intake remains the same.

Additionally, metabolic rates can vary widely among individuals due to genetics, hormonal differences, and other physiological factors, affecting how efficiently the body utilizes energy. These age-related and metabolic factors can make it more challenging for individuals to maintain or lose body fat, even if their diet and exercise regimen remain constant. Understanding these influences helps in tailoring approaches to manage body composition effectively, recognizing that they play a crucial role alongside lifestyle choices.
