4M Obesity Assessment
Mental, Mechanical, Metabolic & Monetary impact.
What your score means
BMI below 18.5 — Underweight. Below the healthy range on the scale this tool uses.
BMI 18.5-22.9 — Normal. Within the healthy range for Asian populations.
BMI 23-24.9 — Overweight. Increased risk on the scale this tool uses, even though this is "normal" on older international charts.
BMI 25-29.9 — Obese Class I. Weight-related risk is raised; the 4M domains show where it is affecting you most.
BMI 30-34.9 — Obese Class II. Weight-related risk is higher again; the 4M domains show where it is affecting you most.
BMI 35 and above — Obese Class III. The highest band on this scale; please discuss your weight and health with a doctor.
BMI not available — Not calculated. Shown when height or weight is missing, so BMI could not be worked out. It is not a risk category.
4M domains — Mental, Mechanical, Metabolic, Monetary. Each domain is reported separately so you can see whether the main impact is on mood, joints and mobility, metabolism, or cost of care.
Frequently asked questions
Why not just use BMI?
BMI describes body size, not health. Two people with the same BMI can differ completely in joint pain, blood sugar and quality of life, which is what the four domains capture.
Why are the BMI cut-offs lower here?
Because metabolic risk in South Asian populations rises at a lower body size than the older international charts assume, this tool marks overweight from 23 and obesity from 25. These are the cut-offs this site uses; they are not copied from any one published standard, and your doctor may work from a different chart.
Is this a diagnosis of obesity?
No. It is a structured awareness tool. Diagnosis and staging in a clinical sense need examination and tests by a doctor.
