A: Basal Metabolic Rate is the minimum level of energy need at rest to function effectively. A person with a high BMR can burn more calories at rest than a person with a low BMR. BMR is based on the level of muscle mass. Daily Caloric Intake is the amount of calories you can consume within 24 hours and still maintain your current weight. Our Ironman scales give the BMR feature and the Innerscan scales give DCI readings.
