Calorie Deficit Formula:
From: | To: |
A calorie deficit is when you consume fewer calories than your body expends, leading to weight loss. For cutting (fat loss while preserving muscle), a moderate deficit of 500-1000 kcal/day is typically recommended.
The calculator uses the simple formula:
Where:
Explanation: The calculator subtracts your chosen deficit from your TEE to determine your daily calorie target for cutting.
Details: A proper deficit allows for steady fat loss while minimizing muscle loss. Too large a deficit can lead to muscle loss, fatigue, and metabolic adaptation.
Tips: Enter your accurate TEE (from a TDEE calculator or metabolic testing) and select your desired deficit level. Beginners should start with a moderate (500 kcal) deficit.
Q1: How much weight will I lose with this deficit?
A: A 500 kcal/day deficit yields ~1 lb/week loss, 750 kcal ~1.5 lbs/week, and 1000 kcal ~2 lbs/week (varies by individual).
Q2: Can I use a larger deficit for faster results?
A: Deficits >1000 kcal/day are not recommended as they often lead to muscle loss and metabolic slowdown.
Q3: Should I adjust my deficit as I lose weight?
A: Yes, recalculate periodically as your TEE decreases with weight loss (every 4-6 weeks).
Q4: What if I'm not losing weight at this deficit?
A: Your TEE may have been overestimated, or you may need to track intake more carefully.
Q5: How should I distribute these calories?
A: Prioritize protein (1.6-2.2g/kg body weight), then balance fats and carbs based on preference.
