Understand Your Body's Energy Needs
By WeCovr
Calculate your BMR and daily calorie requirements.
Understanding your body's energy needs is a cornerstone of good health. Your Basal Metabolic Rate (BMR) is the number of calories your body requires to perform its most basic, life-sustaining functions at rest.
By factoring in your activity level, we can estimate your Total Daily Energy Expenditure (TDEE) — the number of calories you need to maintain your current weight. This figure is key to managing your weight effectively. Use our calculator to get your personalised results.
