Practical Example

Let’s say you weigh 80 kg and want to reach 65 kg. You set a 500-calorie daily deficit, and your start date is October 1st, 2025.

The calculator uses the rule that 7,700 calories ≈ 1 kg of body fat.
With a 500-calorie daily deficit, that’s 3,500 calories per week, which equals 0.45 kg per week.
Your personalized calendar will then show you week-by-week progress, projecting when you’ll hit your goal weight.

So, by following your plan consistently, the calculator may project that you’ll achieve your target weight in approximately 33 weeks—with exact dates and milestones displayed in your calendar.
