1. Body size and composition– overweight people with more muscle mass burn more calories, even during the rest, so they are more likely to have a faster metabolic rate not a slower one.
2. Sex– men probably have less body fat and more muscle mass than does women of the same age that is the reason they burn more calories.
3. Age – when you get older, your muscle mass decreases, which cuts down the rate at which you burn calories.
