What This Means
Healthy weight: low risk for weight-related conditions
A BMI in the 22-24.9 range falls squarely in the healthy weight category as defined by the WHO. This range is associated with the lowest overall risk of weight-related mortality and chronic disease in population studies. Your weight-to-height ratio supports cardiovascular health, healthy joint function, and metabolic efficiency. Continue maintaining balanced nutrition and regular physical activity to sustain this healthy range over time.
How to Improve
Fine-tuning nutrition and activity for better composition
- Track food intake for 1-2 weeks to identify patterns and areas for improvement without obsessive counting
- Increase protein to 1.6-2.0g per kg of body weight, spread across 3-4 meals, to support satiety and muscle retention
- Combine cardiovascular exercise (walking, cycling, swimming) with resistance training for optimal body composition
- Prioritize sleep quality (7-9 hours) as poor sleep disrupts hunger hormones and promotes fat storage
Measuring with Apple Watch
Apple Watch does not measure weight or BMI directly. To track BMI over time, the most convenient method is a smart scale that automatically logs your weight to Apple Health. Popular options include Withings Body+, Renpho Smart Scale, and Eufy Smart Scale. These devices calculate BMI from your weight and height and sync the data wirelessly. Vita can import weight and BMI data from Apple Health to track your trends over time. For the most consistent readings, weigh yourself at the same time each day (ideally morning, after using the bathroom, before eating) and let the smart scale handle the BMI calculation.
Frequently Asked Questions
Is a BMI of 24 good?
Whether a BMI of 24 is good depends on context. The WHO classifies BMI 18.5-24.9 as normal weight, 25-29.9 as overweight, and 30+ as obese. Use the classification chart above to see where 24 falls. Keep in mind that BMI does not account for muscle mass, bone density, or fat distribution, so it is a screening tool rather than a definitive health measure.
How can I lower my BMI from 24?
To lower your BMI, focus on sustainable changes: increase whole food intake, reduce processed foods and sugary drinks, and aim for 150+ minutes of moderate exercise per week. Strength training helps preserve muscle during weight loss. Target 0.5-1 kg of weight loss per week for lasting results. Crash diets cause muscle loss and typically lead to weight regain.
Is BMI 24 the same for men and women?
Yes. The WHO BMI classification uses the same ranges for all adults regardless of gender: underweight (<18.5), normal (18.5-24.9), overweight (25-29.9), obese (30+). However, at the same BMI, men and women typically have different body fat percentages. Women naturally carry more essential fat. For a gender-specific assessment, body fat percentage is a better metric.
What are the limitations of BMI?
BMI only uses height and weight, so it cannot distinguish muscle from fat. A muscular athlete might have a BMI of 27 while being very lean. BMI also does not account for fat distribution (visceral vs. subcutaneous fat), bone density, age-related changes, or ethnic differences in body composition. Body fat percentage and waist circumference provide a more complete picture.
