1. What is Reverse BMI Calculator?

The Reverse BMI Calculator determines how much weight you need to lose to reach a specific BMI target. It calculates the difference between your current weight and the weight that would give you your desired BMI at your height.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Current Weight} \) — Your current weight in kilograms
• \( \text{BMI} \) — Your target BMI value
• \( \text{Height} \) — Your height in meters

Explanation: The equation first calculates your target weight based on BMI and height, then subtracts this from your current weight to determine how much you need to lose.

3. Importance of Weight Loss Calculation

Details: Knowing exactly how much weight you need to lose to reach a healthy BMI can help with goal setting and motivation in weight management programs.

4. Using the Calculator

Tips: Enter your current weight in kg, your target BMI (typically between 18.5-25 for healthy range), and your height in meters. All values must be valid (weight > 0, BMI between 10-50, height between 0.5-2.5m).
