Nutrition expert explains the benefits of a ketogenic diet
There are many, sometimes contradictory, information on what constitutes a healthy diet. The highly praised in recent years low carbohydrate diet is now suspected by a study to shorten lifespan. The professor of anatomy and physiology David Harper is convinced that the current high carbohydrate diet is the root cause of common diseases such as obesity, diabetes and hypertension. It recommends a ketogenic diet as a healthier, low carbohydrate alternative.
The Canadian nutrition expert and oncologist researcher Professor dr. David Harper and his family have followed a ketogenic diet for six years. As a member of the scientific advisory committee of the Institute for Personalized Therapeutic Nutrition in Canada, he attends global nutrition seminars and is currently writing a book on the ketogenic diet. He is not surprised that there is so much confusion about the right diet and he wants to show a clear line to a healthy diet that will help you stay lean and healthy in the long run.
Great confusion on the right diet
"Over the last decade, nutritional science has provided solid evidence that high-carbohydrate diets contribute to obesity and chronic diseases," says the nutrition expert for the Canadian daily Vancouver Sun. low carbohydrate has recently been classified as unhealthy by a study in the journal "The Lancet Public Health", as low carbohydrate diets can reduce overall life expectancy.
Dietary guidelines encourage excessive consumption of carbohydrates
The prevailing food guidelines in Canada are similar to those in Germany. 40 to 65 percent of carbohydrate energy comes from here. According to the nutritionist, these recommendations, which have been common for years, are responsible for the rates of overweight, diabetes and high blood pressure are exploding. Excessive consumption of carbohydrates is the main reason for the rapid increase in common diseases.
The nutritionist explains in human physiology why a high consumption of carbohydrates is associated with pathogenic mechanisms. According to Harper, regular carbohydrate consumption leads to chronic levels of glucose in the blood. The body responds with a constant production of insulin. Over time, insulin resistance would increase in many people, which can lead to diabetes.
Insulin promotes the accumulation of fat
As Professor Harper reports, insulin has another negative effect. It sends a strong signal to the body to store fat. Out of this signal, obesity and high blood glucose levels are rapidly developing, which in turn is the basis of many diseases such as many heart diseases.
How can a ketogenic diet prevent it?
A ketogenic diet reduces carbohydrate consumption to less than 5% of total calories. The main fuel in this diet is not carbohydrates but fats and proteins. "Our glucose levels return to normal, we become less resistant to insulin, we lose fat and reduce the risk of developing a chronic disease," says Harper. Furthermore, the so-called keto bodies are produced by this nutritional form. According to the nutrition expert, these contribute to the protection of the brain and the nervous system and reduce the systemic inflammation, which can trigger cardiovascular diseases. As a cancer researcher, Harper also knows that these keto bodies are currently being tested in scientific studies for their suitability to fight cancer.
The ketogenic diet is not the same as for low carbohydrate diets
In light of the recent study, the nutrition expert comments: The participants in the Lancet study were low in carbohydrates and not ketogenic, according to Harper. 30-40 percent of total calories are still from carbohydrates. The participants would never have reached the state of ketosis, in which only the ketone bodies are produced.
The ketogenic diet has been the standard for millennia
In conclusion, Harper emphasizes that the current standard diet is still very young, measured by human existence. Humanity has been nourished by ketogens for millennia. So, this diet is not a passing fad, but a return to the roots.
Not for all
Anyone planning a diet change should be well informed about the possible consequences. On the one hand, the ketogenic diet is not a fast diet, but a nutritional concept that requires giving up many long-term foods and, secondly, the consequences of this diet are not yet sufficiently studied. (Vb)
