Estimated total daily energy expenditure
1,906 kcal/day
Estimated BMR is 1,105 kcal/day. At active activity, maintenance intake is around 1,906 kcal/day, with common cutting targets near 1,715-1,525 kcal/day.
Female TDEE Benchmarks (Active)
Each row uses age-band average body weight with the same activity multiplier to show how this result compares.
| Age Group | Avg Weight | Avg TDEE | Difference |
|---|---|---|---|
| 18-29 | 155 lb | 2,475 kcal | -569 kcal |
| 30-39 | 168 lb | 2,481 kcal | -575 kcal |
| 40-49 | 176 lb | 2,458 kcal | -552 kcal |
| 50-59 | 178 lb | 2,387 kcal | -481 kcal |
| 60-70 | 173 lb | 2,262 kcal | -356 kcal |
How to Use This TDEE Estimate
A TDEE of 1,906 kcal/day is a practical maintenance starting point. Hold calories near this level for 2-3 weeks and adjust based on weight trend, not day-to-day fluctuations.
For fat loss, most people do well starting with a 10-20% deficit (1,715-1,525 kcal/day here). For muscle gain, add 250-400 kcal/day and monitor weekly averages.
Active assumptions can be off if daily movement differs from plan. Recalculate when body weight changes by about 10-15 lb.
Frequently Asked Questions
Should I eat exactly 1,906 calories every day?
Treat this as a target zone, not an exact prescription. Staying within roughly +/-150 calories while tracking weekly scale trends is usually sufficient.
What deficit should I use for sustainable fat loss?
A 10-20% deficit is commonly used for adherence and muscle retention. For this profile that lands around 1,715-1,525 kcal/day.
Why can TDEE calculators disagree?
Different tools use different formulas, activity assumptions, and rounding. Use calculator output as a starting estimate, then calibrate from real-world results.
