TDEE Guide: How to Turn an Estimate Into a Useful Plan
TDEE is not a perfect truth. It is a starting estimate for daily energy expenditure. The power comes from how you adjust after observing your real trend for two to three weeks.
When TDEE is most useful
- Setting first-pass maintenance calories.
- Planning moderate deficit/surplus targets.
- Comparing activity-level assumptions before dieting.
How to interpret your result
- Pick one calorie target from the estimate and hold it for 14-21 days.
- Track bodyweight trend (not single-day noise).
- Adjust intake by 100-200 kcal/day based on trend direction.
Common mistakes
- Choosing activity level from occasional hard training sessions.
- Changing calories every 2-3 days before enough data exists.
- Ignoring sleep/stress effects on adherence and expenditure.
