Example Calculation

Let’s understand how the calculator works with a practical example:

Current Weight: 80 kg
Target Weight: 70 kg
Desired Weekly Loss: 0.8 kg/week

Step 1: Total Weight to Lose
80 kg − 70 kg = 10 kg

Step 2: Estimated Weeks
Total Weight to Lose ÷ Weekly Loss = 10 ÷ 0.8 = 12.5 weeks
Rounded up, it takes approximately 13 weeks.

Step 3: Estimated Months
Weeks ÷ 4.345 = 12.5 ÷ 4.345 ≈ 2.9 months

So, following this plan, you can realistically achieve your target weight in around 13 weeks or 3 months.
