A study published in the Journal of Physiology raises questions about whether ketogenic diets could be dangerous for those following them. The study conducted by ETH Zurich in conjunction with University Children's Hospital Zurich discovered the side-effects of the diet by feeding mice two different kinds of diet.
Christian Wolfrum, one of the corresponding authors on the paper said, "Diabetes is one of the biggest health issues we face. Although ketogenic diets are known to be healthy, our findings indicate that there may be an increased risk of insulin resistance with this type of diet that may lead to Type 2 diabetes." Tim Spector, professor of genetic epidemiology at Kings College London, said, "This study is a reminder that any extreme restriction diet can cause unforeseen problems." "Humans are omnivores and benefit from a wide variety of foods, and restricting any one group will usually cause us problems longterm. Many people are on carb restricted diets which limits our plant and fibre intakes, with bad effects on our gut health. Ketogenic diets are proving to be an amazing treatment for childhood epilepsy for reasons we don't fully understand and is being tried in other brain disorders, and many people with Type 2 diabetes have come off their medications by cutting out most carbohydrates with the help of their doctor," he noted.
