For the example of calculating TDEE for muscle gain, if your TDEE is 2500 calories, then a 10% calorie surplus will mean that you need to roughly eat 2750 calories a day to ensure you are in a caloric surplus. Conversely, if you are trying to gain muscle then you will require a calorie surplus against your TDEE calculation. The 10% deficit used here is manageable, a deficit of between 10% to 20% is recommended for reducing body fat - too many calories will also mean muscle loss.Ĭalculating TDEE for muscle gain. For the example of calculating TDEE for fat loss, if your TDEE is 2500 calories, then a 10% calorie deficit will mean that you need to roughly eat 2250 calories a day to ensure you are in a caloric deficit. If you are trying to reduce the amount of body fat then you will require a deficit against your TDEE calculation. Once you have this number, then you can use it as the backbone for your training and nutrition goals.Ĭalculating TDEE for fat loss. The single most important reason for calculating TDEE is to do with accurately estimating how many calories your body requires depending on your body composition and daily activity levels.
