One ketogenic diet is a form of low-carb diet, in which low-carbohydrate and high-fat foods are served.
Due to the low intake of carbohydrates The metabolism changes and gets into the so-called ketosis. In this state, the body increasingly uses its fat reserves as an energy source instead of glucose (from carbohydrates).
Because it is considered to be particularly effective in weight loss, many people who want to lose weight swear by the keto diet.
However, more and more experts are warning of health risks associated with diet, such as increased cholesterol levels and vitamin and mineral deficiencies.
Drew Harrisberg from Sydney is also a keto opponent. In an interview with the British newspaper, the sports physiologist revealed why he himself felt “internally overweight” during the ketogenic diet „Daily Mail“.
Exercise physiologist warns keto diet can cause diabetes
According to Harrisberg, the extremely low-carbohydrate diet can help to get rid of excess kilos in a short time. “But the long-term effects are not worth it,” says Harrisberg with conviction.
The Australian native felt physically bad during the time he was on the ketogenic diet. A doctor’s check confirmed that his health was deteriorating.
“The high amount of saturated fat made me carb intolerant and insulin resistant,” explains Harrisberg.
The sports physiologist suspects that he is not an isolated case. Many people who follow the principles of the ketogenic diet have impaired insulin sensitivity.
Insulin resistance is the most common carbohydrate metabolism disorder and leads to serious health problems. it causes diabetes overweighthigh blood pressure and dyslipidemia.
“Insulin sensitivity disorder, along with excess calories and little exercise, increases the risk of developing type 2 diabetes or a pre-diabetes factor many times over,” says Harrisberg.
On the one hand, low-carb and ketogenic diets can keep insulin and blood sugar levels constant. “But these biomarkers say nothing about insulin sensitivity. If you eat mostly fats, you lose your metabolic flexibility. This means that the body can only tolerate small amounts of carbohydrates,” explains the sports expert.
The ketogenic diet contains too many saturated fats
Harrisberg also believes that high-fat foods like bacon, eggs, butter, and coconut oil should not make up the bulk of your daily caloric intake.
“This is particularly worrying when they replace healthy foods such as fruit and potatoes,” says the sports expert.
His conclusion: Although many people have been able to lose weight with the keto diet, the diet is not harmless from a health point of view. In addition, there are no long-term studies that prove the long-term effects of this diet.
