Formula & steps
Deficit logic
- Target calories = TDEE × (1 − deficit%).
- Expected weekly loss is a rough energy-balance estimate.
- Real-world progress still depends on adherence, recovery, and water balance.
Examples
Quick scenario checks
- TDEE 2400
- 15% deficit
Target ≈ 2040 kcal/day.
- TDEE 2800
- 25% deficit
Useful for short phases, but recovery matters.
FAQ
Questions worth ranking for
Each calculator page keeps its own compact FAQ block to widen long-tail coverage.
What is a safe calorie deficit?
Many people do best between 10% and 20%.
Does a 500-calorie deficit always mean 1 lb per week?
Not exactly. Human bodies adapt and water changes can mask the result.
How do I keep muscle while dieting?
Keep protein high, keep lifting, and avoid deficits that are too aggressive for too long.
