TDEE is the amount calories your body burns in a 24 hour period, sleeping, working, exercising, playing and even digesting food!
The IIFYM TDEE Calculator is designed to give you your exact TDEE based on a few key factors (BMR + TOTAL ENERGY EXPENDITURE).
Total Daily Energy Expenditure
TDEE is the most important bit of information available to us when trying to gain muscle or burn fat and lose weight, which is why the IIFYM TDEE Calculator is based on the most exact TDEE formulas available.
Fat Loss Secret
If we eat more calories than our body requires, we will gain weight.
If we eat less calories than our body needs, we will lose weight.
Unless we know exactly what our BMR and TDEE is, we have no way of knowing how many calories to consume while dieting to burn body fat or gain (preserve) muscle. The IIFYM TDEE Calculator is perfect for flexible dieting. The TDEE calculator tells us how many calories we should consume to accomplish our goals in an effective and efficient manner while preserving muscle. In other words, the TDEE calculator allows us to get the best results, in the least amount of time, safely.
Use the IIFYM TDEE Calculator to figure out how many calories your body needs to function at your current activity rate. From there, subtract 15-20% from that number the TDEE Calculator provides in order to see how many calories you should eat daily to burn fat and lose weight at a steady pace. It is not recommended that you subtract more than 25% from your TDEE calculation. The IIFYM TDEE Calculator will help you stay clear of dropping calories too low.
