- Select your activity level honestly, factoring in both exercise and your daily job.
- Use the resulting TDEE to set your daily calorie targets.

Frequently Asked Questions
Why is my TDEE important?
TDEE is the starting point for any diet. If you eat below your TDEE, you lose weight. If you eat above it, you gain weight.
Should I re-calculate my TDEE?
Yes, recalculate your TDEE every time you lose or gain 5-10 pounds, as your calorie needs will change.
Do I add exercise calories to my TDEE?
No. Your activity level multiplier already accounts for your exercise. Adding more calories would lead to double-counting.
Is TDEE accurate for everyone?
It is a highly accurate estimate, but individual metabolisms vary. Use it as a starting point and adjust based on real-world results after 2 weeks.
