Your metabolic rate is the energy measured in calories or Kcalories (1,000 calories), expended by the body at rest to maintain normal functions. This makes up about 70% of the calories the body uses. Your metabolic rate is influenced by quite a number of factors such as gender, age, weight, height, temperature, food, exercise and many other habits. Use the following calculator to help you determine your Kcal (otherwise known as BMR) rate.
