A new study has revealed that the much-loved keto or ketogenic diet could increase the risk of type 2 diabetes. The study was conducted jointly by the ETH Zurich and University of Children’s Hospital Zurich. Keto diet was one of the most highly-searched diets of 2017. With many health and weight loss benefits, keto was hailed by its proponents for being not only a satisfying diet but also effective at weight loss. But the findings of the study are adding to the dissent that keto has been gaining and providing more credence to the critics of the diet.
The study asserts that the keto diet is known to lead to weight loss and is considered metabolically healthy. But it also states that there are conflicting reports on its effect on liver insulin sensitivity.
The study published in the Journal of Physiology involved feeding mice two types of diet, one ketogenic and the other a high-fat diet, both of which can cause the liver to become resistant to insulin. Using specialised procedures, the researchers could determine the effect of internal sugar production from the animal, and the sugar uptake into the issues during the insulin action.
The study said that mice on the keto diet appeared metabolically health in the fasted state after three days of the dietary challenge. But an obesity-causing high-fat diet that was fed to the mice showed elevated insulin levels.
The study revealed that the mice who were fed both keto and high-fat diet were glucose intolerant. The study noted that the ones on keto showed decreased glucose tolerance to a greater extent than high-fat fed animals. It found out that the livers of the mice on keto were not responding well to the insulin, pointing towards insulin resistance. This finding was instrumental in concluding that keto could raise the risk of developing type 2 diabetes.
