Is my weight a health problem? BMI, waist size, and what actually helps
How to read BMI honestly, why waist circumference matters, and what sustainable weight care looks like.

BMI: useful, imperfect
BMI is your weight in kilograms divided by your height in metres squared. As a broad guide for adults: 18.5–24.9 is the healthy range, 25–29.9 is overweight, and 30 or above is classed as obesity. It is a screening tool, not a verdict — a muscular person can score 'overweight' while carrying little fat.
Why your waist tells you more
Fat stored around the organs — the belly, not the hips — is what drives diabetes, hypertension and heart disease risk. A waist above roughly 94 cm for men or 80 cm for women signals raised risk even when BMI looks moderate. A tape measure is a better early-warning tool than a mirror.
What does not work
Crash diets, teas, waist trainers and 'flat tummy' products do not produce lasting fat loss — most produce a rebound. Weight that comes off in weeks tends to come back with interest, because nothing about daily life actually changed.
What does
The boring, proven combination: modest calorie reduction you can sustain, protein and fibre that keep you full, 30 minutes of movement most days, sleep, and — this is the part most people skip — tracking, so the trend is visible. A 5–10% loss held for a year improves blood pressure, sugar and cholesterol measurably.
If your BMI is 30+ or your weight comes with raised sugar or pressure, this is a medical matter that deserves a doctor's structured support, not a willpower verdict. That is exactly what a managed programme is for.
