The aim of the review and meta-analysis was to examine the long-term (more than 12 months) effects of high-fat v low-fat diet consumption on specific markers of cardiovascular risk in pre-diabetic and diabetic individuals. The analysis included 14 trials and 1,753 subjects.
The study found:
(a) Those on high fat regimens had a significant decrease in triglyceride levels.
(b) Those on high fat regimens had a significant decrease in diastolic blood pressure.
(c) Those on high fat regimens had a significant decrease in fasting glucose levels levels.
(d) Those on high fat regimens had a significant increase in high density lipoprotein (HDL) cholesterol levels.
The high fat diet improved specific markers of cardiovascular risk in pre-diabetic and diabetic individuals.
The lead researcher of the review, Lukas Schwingshackl from the University of Vienna, concluded: "High fat and low fat diets might not be of equal value in the management of either pre-diabetes or type 2 diabetes, leading to emphasis being placed on the recommendations of high fat diets".
