First, lean mass and fat mass could not be differentiated for a given BMI across age, sex and race[3].

Why do Type 2 diabetics gain weight?

Also, weight gain in people with type 2 diabetes makes blood sugar levels even harder to control. People with type 2 diabetes have a condition called insulin resistance.
