Basal Metabolic Rate

The Basal Metabolic Rate (or Basal Rate) is the rate at which your body burns calories while you rest.

Proponents of the Zone diet often argue that the (Zone-recommended) 40:30:30 proportion of calories from carbohydrates, protein and fat maintains the body's basal rate, while diets with a higher proportion of calories from carbohydrates tend to decrease the basal rate.
