This paper is a meta-analysis of 19 studies which compared the effects of replacing dietary fat with carbohydrate in patients with type II diabetes.
The average composition of the diets were:
(i) 58% carbohydrate, 24% fat (low fat, high carbohydrate diet).
(ii) 40% carbohydrate, 40% fat (high fat diet).
The study found:
(a) The (bad) fasting insulin levels were 8% higher on the low fat, high carbohydrate diet compared to the high fat diet.
(b) The (bad) triglyceride levels were 13% higher on the low fat, high carbohydrate diet compared to the high fat diet.
(c) The beneficial high density lipoprotein (HDL) cholesterol levels were 6% lower on the low fat, high carbohydrate diet compared to the high fat diet.
The findings of the study suggest that a high fat diet may be beneficial in the treatment of diabetes compared to a low fat, high carbohydrate diet.
