The total daily energy expenditure calculator, estimates the total calories your body burns in a day. It factors in basal metabolic rate (BMR), physical activity, and the thermic effect of food. To determine your TDEE, input your age, gender, weight, height, and activity level into the calculator. TDEE helps set daily calorie goals for weight maintenance, loss, or gain. Understanding your TDEE is crucial for creating effective nutrition and fitness plans tailored to your goals. Remember, this estimation provides a starting point; adjustments may be necessary based on individual factors and progress monitoring.
