Keto Diet Beats Mediterranean for Prediabetes
27 Aug
Summary
- Keto diet significantly improved prediabetes markers in study participants.
- Liver fat decreased by 67% with Keto diet versus 45% with others.
- Half of Keto dieters no longer met prediabetes criteria.
Research indicates that a ketogenic diet may offer significant health advantages for individuals struggling with obesity and prediabetes. A study involving 42 participants with obesity, prediabetes, and fatty liver disease compared the effects of ketogenic, Mediterranean, and low-fat diets over four to five months.
All participants achieved a 10% body weight loss, leading to improved insulin sensitivity. However, the ketogenic diet group saw a remarkable 67% average decrease in liver fat, significantly higher than the 45% reduction observed in the Mediterranean and plant-forward diet groups.
Furthermore, participants on the ketogenic diet experienced a greater increase in glucagon, a hormone that promotes fat loss, and a more substantial reduction in blood insulin levels. This resulted in about 50% of the ketogenic group no longer meeting prediabetes criteria, compared to 29% and 7% in the other groups.
Despite the high fat content of the keto diet, study authors noted no increase in blood fat or cholesterol levels, which was a surprising finding. Experts, however, emphasize the need for longer-term studies to assess the sustainability and comparative risks of the ketogenic approach.
