Fig. 2. Changes in the lipid profile in diabetic and non-diabetic subjects after the administration of a low-calorie diet or a ketogenic diet for 24 wk. Diabetic and non-diabetic
participants in the low-calorie ketogenic diet group showed a significant decrease (P < 0.0001) in triglycerides (A), total cholesterol (B), and LDL (D) levels, whereas the HDL
level (C) was significantly (P < 0.0001) increased. Black circles, ketogenic and non-diabetic; black triangles, ketogenic and diabetic; HDL, high-density lipoprotein; LDL, lowdensity
lipoprotein; white circles, low calorie and non-diabetic; white triangles, low calorie and diabetic.
