The Basal Metabolic Rate (BMR) is the amount of energy you need while resting in a temperate environment during the post-absorptive state, or when your digestive system is inactive. In such a state, your energy will be used only to maintain your vital organs, which include the heart, lungs, kidneys, the nervous system, intestines, liver, lungs, sex organs, muscles, and skin. The BMR decreases with age and increases with muscle mass.
Are you overweight? Maybe, if you get a bmi calculation that indicates you are, this may not always be accurate. Body Mass Index (BMI) can be misleading. This is because the BMI does not take into account your body composition. For example, your body fat percentage in comparison to your percentage of muscle mass is an important factor. Check out the mathematical formula to check your body fat percentage.
Determine your body fat percentage with our body fat calculator. Use a tape measure to determine your waist, hip and neck circumference. Then input your gender and measurements below to receive a body fat index based on average values. The body fat index is not an indicator of fitness level since the calculation is made with no regard to height or weight.
