What is TDEE?
The amount of energy you eat each day in calories is TDEE, the total daily energy expenditure. TDEE is best calculated on the basis of your BMR or basal metabolic rate and level of activity. BMR is the calories you burn at rest every day.
Your total daily energy includes all the energy you use when sleeping, working and even eating. If you are trying to get the right diet for bulking or cutting, it is important to know your TDEE.
Your TDEE is often called the calorie maintenance level of your fitness products. This is the quantity of calories you need every day to keep your weight. If you know your total daily energy expenditure, you can either add calories for bulk per day or reduce fat calories.
