Fig. 1. Changes in the percentage of body weight (A), blood glucose level (B), and
level of glycosylated hemoglobin (C) in diabetic and non-diabetic subjects after the
administration of a low-calorie diet or a low-carbohydrate ketogenic diet for 24 wk.
A significant difference (P < 0.0001) in body weight was noticed in the low-calorie
and low-carbohydrate ketogenic diet groups compared with their initial (week 1)
and final (week 24) measurements. The ketogenic diet was more effective than the
low-calorie diet. The blood sugar level significantly decreased in the two groups.
The effectiveness of the low-carbohydrate ketogenic diet was much greater (P <
0.0001) in the diabetic group on the low-carbohydrate ketogenic diet than on the
low-calorie compared with week 1 and week 24 blood glucose levels. In the diabetic
group, the glycosylated hemoglobin level significantly decreased with the
low-carbohydrate ketogenic diet compared with the two diets. Black circles,
ketogenic and non-diabetic; black triangles, ketogenic and diabetic; white circles,
low calorie andnon-diabetic; white triangles, low calorie and diabetic.
