Frequently Asked Questions
A BMI of 18.5–24.9 is considered healthy for most adults. Below 18.5 is underweight, 25–29.9 is overweight, and 30+ is obese. However, BMI is just one tool and should be interpreted with other health indicators.
BMI can be misleading for athletes and highly muscular individuals. Muscle weighs more than fat, so athletes may show as "overweight" despite having low body fat. In these cases, body fat percentage is a better indicator of health.
The WHO BMI categories use the same ranges for both men and women. However, women naturally have higher body fat than men at the same BMI. Some researchers suggest using different thresholds, but the standard 18.5–24.9 range is widely used for both.
To reduce BMI, focus on: balanced diet with a modest calorie deficit, regular aerobic exercise (150+ min/week), strength training to preserve muscle, and adequate sleep. Consult a healthcare provider before making significant lifestyle changes.
