📏 How to estimate body fat: If you don't know your body fat %, leave the field blank — the calculator will use the Mifflin-St Jeor formula. If you have a DEXA scan, calipers, or BodPod result, enter it to enable the more accurate Katch-McArdle formula using lean body mass.
Adaptive TDEE allows to estimate exactly how many calories the body really uses every day. Rather than depend on online calculators and formulas, that assume based on age and level of activity, it bases on actual data. It looks at the amount of food that enters, and at the changes in body weight.

When weight stays same, that calorie amount answers for keeping it. If weight drops more quickly than assumed, the rating of TDEE should rise.
Find Your True Daily Calories with Adaptive TDEE
The main idea is easy to understand. Enter daily calories and weight, and over time the numbers will sort themselves. A common tool for all that is the adaptive TDEE sheet, that works with weekly averages.
It requires patience however. After around four weeks of entries, the sheet really gains accuracy. Since the first day, the values jump around and seem hard.
But after some weeks of entries, the numbers become reliable.
Average TDEE calculator can serve as first step. They apply multipliers based on activity level, but many folks choose the wrong one. That can lead to ratings, that err by thousands of calories too much or too little.
By means of adaptive follow-up, the usual daily swings in weight smooth out, and general trends show. Those trends then point, whether to add or lower calories.
There are also apps that do that. One free online app allows direct entry of calories and weight. After around ten entries, it delivers a TDEE value that adapts to body and usual changes.
Another app called Adaptive TDEE Calculator works similarly. Both tools give same results, when one provides them with identical data.
The results commonly surprise. Some that thought that their TDEE is barely above 1200 calories, found by means of the adaptive sheet that it indeed reaches 1900. Other folk found that their TDEE is around 2400, witch means that eating 1400 calories created a 1000 calorie daily gap and caused loss of around two pounds per week on average.
Muscle has a role here also. Adding a pound of muscle raises the daily TDEE by around 10 to 12 calories. Bigger muscles use more energy during workouts.
Think about muscle as an investment that always gives profit even during rest, while cardio exercise is like hourly pay, that will end when one stops to work.
During weight loss, TDEE naturally sinks. People call that metabolic adaptation, and it can lower TDEE more than what you expect from the weight alone. One way to control that is to change the calorie entry, which tricks the body to keep theweight loss going.
A good starting point is a 500 calorie daily gap, that should lead to loss of around one pound per week.
