Muscle needs more energy than fatty tissue
Regular exercise can boost metabolic rate
Builds muscle to boost metabolic rate
Men tend to have a slightly higher rate than women
Physically bigger people are likely to have a higher metabolic rate
More cells means more energy your body needs
Genetic factors can affect this

Builds muscle to boost metabolic rate
People who exercise regularly are healthier
Less likely to suffer from health problems
Can still be malnourished if you're physically fit
Diet isn't balanced
Inherited factors
Health can depend on genes
