Healthy Weight Calculator

A healthy weight is typically one that gives you a BMI between 18.5 and 24.9. However, healthy weight also depends on age, muscle mass, bone density, body fat distribution, and overall health. BMI alone doesn't account for these factors.

Key factors include: height (taller people have higher healthy weights), gender (men typically have higher muscle mass), age (older adults may have slightly higher acceptable weights), frame size (bone structure), and muscle mass (athletes may weigh more).

We use the Devine formula as a baseline: Men: 50 kg + 2.3 kg per inch over 5 ft. Women: 45.5 kg + 2.3 kg per inch over 5 ft. This is then adjusted for frame size and constrained within the healthy BMI range.

BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat mass. Athletes or muscular individuals may have high BMI but low body fat. For a complete picture, consider waist circumference, body fat percentage, and overall fitness.

For safe weight loss, aim for 1-2 pounds (0.5-1 kg) per week through a 500-1000 calorie daily deficit. For weight gain, aim for 0.5-1 pound (0.25-0.5 kg) per week with a 250-500 calorie surplus plus strength training.
