And this is being their recommendation of their lifestyle therapy...
"Lifestyle therapy begins with nutrition counseling and education. All patients should strive to attain and maintain an optimal weight through a primarily plant-based diet high in polyunsaturated and monounsaturated fatty acids, with limited intake of saturated fatty acids and avoidance of trans fats. Patients who are overweight (body mass index [BMI] of 25 to 29.9 kg/m2) or obese (BMI ≥30 kg/ m2) should also restrict their caloric intake with the goal of reducing body weight by at least 5 to 10%. As shown in the Look AHEAD (Action for Health in Diabetes) and Diabetes Prevention Program studies, lowering caloric intake is the main driver for weight loss (3-6)."
It would take a while for low carbs high fats to be accepted...
Also the failure to mention/consider hyperinsulinemia or how to normalize insulin levels rather glaring. The whole T2D treatment guideline is very glucose centric.
