Calorie Deficit for Weight Loss

Also known as: Weight Loss Calorie Formula

\text{Deficit} = TDEE - \text{Calorie Intake}

Deficit = TDEE - Calorie Intake

What It Calculates

To lose weight, consume fewer calories than you burn. A deficit of ~3,500 calories equals roughly 1 pound of fat loss. A 500 cal/day deficit targets ~1 lb/week loss.

Worked Examples

1Deficit = 2500 - 2000 = 500 cal/day

2Weekly deficit = 500 × 7 = 3,500 cal ≈ 1 lb/week

Result: ~1 lb/week loss

Greșeli comune

The 3,500 cal/lb rule is an approximation

Very large deficits (>1000 cal/day) can be counterproductive and unhealthy
