Women naturally have a higher percentage of body fat than men (between 20% and 25% is healthy in women, versus 10–20% in men). This is completely normal and necessary for hormonal and reproductive functions.
| Category | BMI | Health risk |
|---|---|---|
| Underweight | Less than 18.5 | Malnutrition, anemia, osteoporosis |
| Normal | 18.5 – 24.9 | Minimal risk |
| Overweight | 25 – 29.9 | Slightly elevated risk |
| Obesity | 30 or more | Elevated to very high risk |
During pregnancy, the standard BMI does not apply because weight varies naturally week by week. Doctors use specific gestational weight gain tables based on pre-pregnancy BMI.
If you are pregnant, consult your doctor or midwife to learn how much weight is healthy to gain during your pregnancy.
During menopause, hormonal changes can redistribute body fat toward the abdomen, increasing cardiovascular risk even with a normal BMI. That is why in women over 50, waist circumference is an important complementary indicator (healthy: less than 88 cm in women).
