Common questions

What is TDEE for athletes?

TDEE estimates total daily calories including exercise. Pick an activity level honestly and adjust weekly based on performance and weight.

BMR vs TDEE — which should I use?

Use BMR for resting baseline; TDEE when you train or move regularly. Most active users plan with TDEE.

Can I use these for competition prep?

They help rough planning only. Coaches and clinicians should guide aggressive cuts or medical conditions.
