Formula Behind the Calculator
This tool is based on simple and realistic weight loss mathematics.
1. Weight to Lose Formula
W=C−G
Where:
- W = Weight to lose
- C = Current weight
- G = Goal weight
2. Time in Weeks Formula
Tweeks=RW
Where:
- Tweeks = Time in weeks
- W = Weight to lose
- R = Weekly weight loss rate
3. Time in Months Formula
Tmonths=4.345Tweeks
(1 month ≈ 4.345 weeks)
Example Calculation
Let’s understand how the calculator works with a real-life example.
Given:
- Current weight = 80 kg
- Goal weight = 65 kg
- Weekly loss rate = 0.5 kg/week
Step 1: Calculate Weight to Lose
80 - 65 = 15 kg
Step 2: Calculate Weeks Required
15 ÷ 0.5 = 30 weeks
Step 3: Convert to Months
30 ÷ 4.345 = 6.9 months
Final Result:
- Weight to lose: 15 kg
- Time required: 30 weeks
- Time in months: 6.9 months
This helps you understand that safe weight loss takes time and consistency.
Healthy Weight Loss Rate
Experts recommend losing weight gradually for long-term success.
Safe range:
- 0.25 kg per week (slow but steady)
- 0.5 kg per week (ideal and healthy)
- 1 kg per week (aggressive but possible for some people)
Why slow weight loss is better:
- Prevents muscle loss
- Improves metabolism
- Reduces health risks
- Easier to maintain
