BMI Misclassifies 1 in 3 People. Body Composition Is the Real Truth of Your Body.

BMI has been the standard parameter for assessing metabolic risk for decades. But research is clear: it misclassifies at least 1 in 3 people.

It does not distinguish fat mass from muscle mass, does not identify fat distribution, and does not detect visceral fat — the most dangerous.

The scientific problem with BMI

BMI = kg/m². An athlete at 90 kg of muscle and a sedentary person at 90 kg of abdominal fat have the same BMI — but radically different risk profiles.

A subject with normal BMI can have low muscle mass and high visceral fat (TOFI — Thin Outside, Fat Inside).

Change in body shape is predicted by variation in two body composition characteristics (adiposity and muscularity), not one alone.

Someone dieting and exercising may gain muscle while losing fat — weight stable. BMI says nothing changed. Body composition tells the truth.

Normal weight obesity: the clinically critical case

Normal weight obesity: normal BMI, low muscle mass, high visceral fat. Associated with insulin resistance, metabolic syndrome and increased cardiovascular risk — all invisible to BMI.

How the Digital Twin measures body composition

The Digital Twin integrates data from bioimpedance smart scales or in-clinic InBody analysis to measure muscle mass, total body fat, visceral fat and body water. Updated week by week — a dynamic profile, not a snapshot.
