Ideal Weight Formula:
From: | To: |
The Ideal Weight Body Fat calculation determines your target weight based on your current weight, current body fat percentage, and desired body fat percentage. This helps set realistic weight goals for fitness and health purposes.
The calculator uses the formula:
Where:
Explanation: This formula calculates how much weight you need to lose or gain to reach your target body fat percentage while maintaining lean body mass.
Details: Calculating your ideal weight based on body fat percentage provides a more accurate target than general weight charts, as it accounts for body composition rather than just total weight.
Tips: Enter your current weight in kilograms, current body fat percentage, and desired body fat percentage. All values must be valid (weight > 0, body fat percentages between 0-100).
Q1: How accurate is this calculation?
A: This calculation provides an estimate based on maintaining current lean body mass. Individual results may vary based on factors like muscle gain/loss during weight change.
Q2: What are healthy body fat percentages?
A: For men: 8-19% (athletic), 20-24% (fitness), 25%+ (obese). For women: 21-33% (athletic), 34-39% (fitness), 40%+ (obese).
Q3: How should I measure body fat percentage?
A: Use methods like calipers, bioelectrical impedance scales, DEXA scans, or hydrostatic weighing for accurate measurements.
Q4: Can I use pounds instead of kilograms?
A: Yes, the formula works with any weight unit as long as you're consistent (use pounds for both current and ideal weight).
Q5: What if I want to gain muscle while losing fat?
A: This calculation assumes maintaining current lean mass. For muscle gain, the calculation becomes more complex as both fat loss and muscle gain occur simultaneously.
