The Science Behind Weight Loss
Weight loss is based on a simple energy balance principle:
If you burn more calories than you consume, you lose weight.
This is called a calorie deficit.
Key Formula Used in the Calculator
1. Weight Loss Calculation
Weight Loss=Current Weight−Target Weight
2. Total Calorie Deficit Required
Total Deficit=Weight Loss×7700
📌 (1 kg of fat ≈ 7700 kcal)
3. Weekly Weight Loss
Weekly Loss=WeeksWeight Loss
4. Weekly Calorie Deficit Needed
Weekly Deficit=WeeksTotal Deficit
5. Days Required to Reach Goal
Days=Daily Calorie DeficitTotal Deficit
Understanding Calorie Deficit in Simple Terms
A calorie deficit means your body uses stored fat for energy.
For example:
- If you eat 2000 kcal/day
- But burn 2500 kcal/day
- You create a 500 kcal deficit
Over time, this leads to fat loss.
Example Calculation
Let’s understand how the calculator works with a real example.
Given Inputs:
- Current Weight = 80 kg
- Target Weight = 70 kg
- Time = 10 weeks
- Daily Calorie Deficit = 600 kcal
Step 1: Weight to Lose
80 - 70 = 10 kg
Step 2: Total Calorie Deficit
10 × 7700 = 77,000 kcal
Step 3: Weekly Weight Loss
10 ÷ 10 = 1 kg per week
Step 4: Weekly Deficit Required
77,000 ÷ 10 = 7,700 kcal per week
Step 5: Days Required
77,000 ÷ 600 ≈ 128 days
Final Result:
- Weight to lose: 10 kg
- Weekly loss: 1 kg
- Total deficit: 77,000 kcal
- Estimated days: 128 days
