⚖️ BMI · BMR · TDEE

Body mass index with both WHO and Asian cut-offs, resting energy (Mifflin-St Jeor) and daily calorie needs by activity level — then the part that actually helps: what that calorie number means in real food (how many bowls of phở, how much of your day one bubble tea eats), how to split it across four meals, how much protein, carbs and fat to put on the plate, and one piece of advice for your goal.

⚠️ Educational only — BMI does not distinguish muscle from fat, and calorie formulas are population averages (±10%). They do not replace advice from a doctor or dietitian. Asian cut-offs (WHO expert consultation 2004): overweight from BMI 23, obesity from 25 — lower than the general WHO thresholds because health risks rise earlier at the same BMI in Asian populations. Food calories: Vietnam Food Composition Table (National Institute of Nutrition, Ministry of Health), international dishes per USDA — rounded to the nearest ten; the same dish varies 20–40% between eateries depending on oil, meat and sugar.

Frequently asked questions

How is BMI calculated?
BMI = weight (kg) divided by height squared (m²). For 60 kg and 1.65 m, BMI ≈ 60 / (1.65 × 1.65) ≈ 22.0.
What BMI is healthy for Vietnamese people?
Using Asian thresholds: under 18.5 is underweight, 18.5–22.9 normal, 23–24.9 overweight, and 25 or above is obese. These are lower than the general WHO cut-offs because Asian bodies accumulate fat at a lower BMI.
Does BMI truly reflect health?
BMI only estimates from height and weight and cannot tell muscle from fat, so very muscular people may be mislabeled overweight. Read it alongside waist size and other measures.
