DEXA vs BMI: Why Body Composition Changes Everything
BMI was invented in 1832. It cannot distinguish between muscle and fat. DEXA scanning reveals what your scale never could.

The scale weighs muscle, water and fat together, and it reads a South Asian body against lines set for other populations. Before changing anything, it helps to know what is actually there and how your metabolism is handling it.
Book an assessmentWhat we look at
Shows how hard the body is working to keep sugar normal.
Insulin resistance, estimated from fasting glucose and insulin.
Average blood sugar over about three months.
An underactive thyroid can cause weight gain.
Often rises with insulin resistance.
A liver enzyme that can rise when fat builds up in the liver.
Which tests
A physician reads your body composition, blood and history together, including medicines that can affect weight. You leave knowing what the numbers show and what they do not. Any plan is made with you, not handed out.
The evidence, honestly
General education, not advice for you. What suits you depends on your results and history, and a physician decides it with you.

Not useless, but blunt. It cannot tell muscle from fat, and for South Asian adults the lines on most reports are set too high. Waist-to-height ratio and a body-composition scan add what BMI misses.
An underactive thyroid can, and TSH is the screening test. Most stalled weight is not thyroid, which is why it is one marker among several, not the whole answer.
