TOFI not Tofu (the food). Read first about it in The Diabetes Code

BMI is not a good predictor of T2 diabetes. A waist circumference is a better indicator.

Visceral fat accumulates inside and around the intra-abdominal organs - like kidney, liver, etc. In contrast subcutaneous fat is fat deposited under the skin.

Waist to heigh ratio should be less than half. So, for me waist should be under 89cms or 35 inches.
