Scientists at the National Jewish Health Hospital in Denver, Colorado, led by Dr. Andrew Freeman, after reviewing numerous studies on ketogenic diets and intermittent fasting, have found that the two diets not only have health benefits, but also cardiovascular risks. The short-term application of a keto diet is good, according to the researchers, for example, to lose weight quickly. However, the experts advised against a longer-term application because saturated fats in animal products, which are predominantly consumed, such as red meat, bear risks for cardiovascular diseases and cancer, but also for the kidneys. The researchers warn expressly that kind and quantity of the consumed fats, which are to serve for the power production, are bad, because they contained too many unsaturated and thus unhealthy fatty acids. The consequence is then too high Lipidwerte in the blood of the Di?tthaltenden. Also, indications of stiffening of arteries and thus an untimely death is present to the specialists after evaluation of numerous studies, because laymen, who keep this diet, do not pay attention differently than study participants strictly to the kind of the fats, which are crucial for the healthy attitude. In addition, according to the analysis of the scientists, weight loss is often not lasting enough. Furthermore, it is not entirely clear whether the weight loss is caused by the condition of ketosis or simply by reduced calorie intake. Starvation attacks during the keto diet or intermittent fasting inevitably lead probably also to unhealthy food consumption, which also has cardiovascular effects. The experts also criticize that animal experiments conducted in connection with these diets provide too little evidence of effects in humans. Diabetics, for example, would need the advice of doctors before starting such a diet, because skipping meals while fasting could lower blood sugar levels to such an extent that a hyperglycemic state of shock is imminent. The experts of the National Jewish Health, therefore, recommend other forms of nutrition, such as a Mediterranean diet and a predominantly vegetable diet with lots of fresh fruit and vegetables, nuts and also wholemeal products and pulses, so that no cardiovascular problems can arise in the first place.
