Your metabolic rate is influenced by many factors – including age, gender, muscle-to-fat ratio, amount of physical activity and hormone function.

What is the major factor that determines basal metabolic rate?

The major factor determining basal metabolic rate (BMR) is fat-free mass (FFM) (1–3), with some studies finding an additional contribution of fat mass (FM) (4, 5), but others failing to find such an effect (6, 7).

What is the biggest factor in metabolism?

The biggest component of your metabolism, (50-80%) of the energy used, is your basal metabolic rate (BMR), which is the energy your body burns just to maintain functioning at rest. Here are ten factors that affect BMR and metabolism: 1. Muscle mass.
