The Science Behind Weight Loss Calculation
The calculator is based on a widely accepted nutrition principle:
1 kg of fat ≈ 7700 calories
This means to lose 1 kilogram of body fat, you need a total calorie deficit of approximately 7700 kcal.
Key Formula Used in the Calculator
Weight to Lose
W=C−T
Where:
- W = Weight to lose
- C = Current weight
- T = Target weight
Total Calories Needed
Calories=W×7700
Estimated Days
Days=Daily DeficitW×7700
Estimated Weeks
Weeks=7Days
Fat Loss Rate
Rate=WeeksW
Example Calculation
Let’s understand the process with a real example.
Given:
- Current Weight = 80 kg
- Target Weight = 70 kg
- Daily Calorie Deficit = 500 kcal
Step 1: Weight to Lose
80 - 70 = 10 kg
Step 2: Total Calories Needed
10 × 7700 = 77,000 kcal
Step 3: Estimated Days
77,000 ÷ 500 = 154 days
Step 4: Estimated Weeks
154 ÷ 7 = 22 weeks
Step 5: Fat Loss Rate
10 ÷ 22 = 0.45 kg per week
Final Result:
- Weight to lose: 10 kg
- Time required: ~154 days
- Duration: ~22 weeks
- Fat loss rate: ~0.45 kg/week

Understanding Calorie Deficit
A calorie deficit is the foundation of weight loss. It means:
You burn more calories than you consume.
For example:
- Eating 2000 kcal/day
- Burning 2500 kcal/day
- Deficit = 500 kcal/day
The higher the deficit, the faster the weight loss—but it must remain safe and sustainable.

- 0.25 kg to 1 kg loss per week is safe
