The Reverse BMI Calculator helps determine how much weight you need to lose to reach your desired Body Mass Index (BMI). It calculates the difference between your current weight and the target weight for your desired BMI.
The calculator uses the formula:
Where:
Explanation: The formula calculates your target weight based on the desired BMI and height, then subtracts it from your current weight to determine how much weight you need to lose.
Details: Calculating the specific amount of weight needed to reach a healthy BMI helps set realistic weight loss goals and provides a clear target for weight management programs.
Tips: Enter your current weight in kg, desired BMI value, and height in meters. All values must be positive numbers. The calculator will show how many kilograms you need to lose to reach your target BMI.
Q1: What is a healthy BMI range?
A: A healthy BMI typically ranges from 18.5 to 24.9. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Q2: How accurate is this calculation?
A: The calculation provides a mathematical estimate based on the BMI formula. Individual results may vary based on body composition and other factors.
Q3: Should I use this calculator if I'm very muscular?
A: BMI may not accurately reflect body composition for very muscular individuals, as muscle weighs more than fat. Consider body fat percentage measurements instead.
Q4: How often should I recalculate my weight loss target?
A: Recalculate periodically as you lose weight, or if your height changes (for growing children/teens).
Q5: Is this suitable for children?
A: BMI calculations for children require age and sex-specific percentiles. This calculator is designed for adults.
