What is TDEE?
Performance and body metrics

Choosing the right activity level matters. Overestimating your movement often leads to calorie targets that are too high.

A small calorie deficit can support steady fat loss, while a modest surplus can support muscle gain. Maintenance sits near your estimated TDEE.
Use your real-world progress over two to four weeks to fine-tune the number.

How accurate is TDEE?
TDEE is an estimate, not an exact number. It works best as a starting point that you adjust based on weight trends and energy levels.
Should I use sedentary or lightly active?
Pick the lower option if you mostly sit during the day and only train a few times per week. Many people overestimate their activity.
