Mathematical Formulas & Calculation Methods

Calorie Deficit Weight Loss Timeline

Based on 1 kg of fat ≈ 7,700 kcal (or 1 lb of fat ≈ 3,500 kcal).

Days to Goal = (Weight to Lose in kg × 7,700) / Daily Deficit

Worked Step-by-Step Examples

Example 1: Losing 10 kg with a 500 kcal/day Deficit (2,400 kcal TDEE)

"Calculate target daily calorie allowance and estimated completion days."

Steps:

Current Weight = 85 kg. Goal Weight = 75 kg. Weight to lose = 10 kg.
Total calories to burn = 10 × 7,700 = 77,000 kcal.
Daily Deficit = 500 kcal/day → Target Daily Allowance = 2,400 - 500 = 1,900 kcal/day.
Days to Goal = 77,000 / 500 = 154 Days (~22 Weeks).

Result: Daily Target = 1,900 kcal/day (Target Date: 154 Days / ~22 Weeks)
