1According to the BMI classification by the WHO
This model is based on Fats V3.1 morphed to a BMI of 29 kg/m² using a realistic physics-based morphing approach, which shrinks (or expands) specific tissues. The morphing is performed using a bio-mechanical solver with hyper-elastic soft tissues and rigid bones. Local shrinking (or expansion) is modeled using a thermal expansion analogy. The tissues remain the same as in the original model.
