- Goal Weight = 65 kg
- Weekly Loss Rate = 0.5 kg/week
- Start Date = 1 January 2026
Step 1: Total Weight Loss
80 − 65 = 15 kg
Step 2: Estimate Weeks
15 ÷ 0.5 = 30 weeks
Step 3: Calculate Target Date
Start Date + 30 weeks ≈ End of July 2026
Final Result:
- Total Weight Loss: 15 kg
- Time Needed: 30 weeks
- Target Date: Around July 2026
