BMI Calculator for Women — Free, Australian, with Personalised Meal Recommendations
This is Foober's free BMI (Body Mass Index) calculator for women. Enter your height and weight in metric (cm/kg) or imperial (ft/lb) and the calculator returns your BMI, the WHO category it falls into, and a meal-plan recommendation tailored to your result and goal. The calculation is instant and does not require an account.
How BMI Is Calculated
BMI = weight in kilograms divided by height in metres squared (kg/m²). Example: a woman at 165cm and 65kg has a BMI of 65 ÷ (1.65 × 1.65) = 23.9, which sits in the "normal weight" category.
BMI Categories (WHO standard, adult women)
- Under 18.5 — Underweight. May indicate a need to increase calorie and protein intake; the muscle-gain range often suits.
- 18.5 to 24.9 — Normal weight. Balanced eating with adequate protein supports performance and lean mass.
- 25.0 to 29.9 — Overweight. High-protein, calorie-controlled meals support sustainable gradual loss without losing muscle.
- 30.0 and above — Obese. Usually best paired with medical guidance; portion-controlled, no-added-sugar meals are a good baseline.
BMI Considerations Specific to Women
BMI doesn't account for the natural higher essential body-fat percentage in women, hormonal weight fluctuation, pregnancy, post-partum recovery, or menopause-related body composition shifts. It also doesn't distinguish muscle from fat — strength-trained women often register as "overweight" by BMI despite low body fat. Use BMI alongside waist circumference, body composition measurements, and how you feel.
Foober Meal Recommendations by BMI Bracket
- Underweight (BMI <18.5) — the muscle-gain range offers 500+ cal LARGE meals with 45g+ protein for gradual healthy gain.
- Normal (18.5–24.9) — try the high-protein range or the curated weekly plans.
- Overweight (25.0–29.9) — the weight-loss range features under-350-cal meals with 30g+ protein to maintain muscle in a deficit. Particularly suited for GLP-1 medication users (Ozempic, Wegovy, Mounjaro).
- Obese (30.0+) — combine the weight-loss range with the keto range for low-carb, no-added-sugar options. Best paired with medical guidance.
