A 12-week periodic ketogenic diet (30-50g carbs, 130g fat, 60g protein, ~1500 kcal) significantly improves body weight, BMI, waist circumference, fasting blood glucose, fasting insulin, HbA1c, and lipid profiles (TG, TC, LDL) in newly diagnosed overweight/obese T2DM patients compared to routine diabetes diet.

If you are newly diagnosed with Type 2 Diabetes and overweight, a 12-week ketogenic diet (approx. 1500 calories, very low carb) can significantly improve your weight, blood sugar, and cholesterol better than standard diabetes advice. However, it is difficult to sustain long-term due to taste and adherence issues. It serves as an effective short-term intervention to reduce medication needs and improve metabolic health.
