Markert Diet
The Markert Diet is a weight loss diet that was invented by the doctor Dieter Markert and is marketed by him. Strictly speaking, it is not a diet, but a form of therapeutic fasting . In the meantime, however, Markert has also published a “new Markert diet” in which people not only drink but also eat something.
The principle
The original Markert Diet, which came out as a book in 1996, is a pure drinking fasting diet that consumes a maximum of 500 kilocalories per day. In addition to vegetable broth and juices, a protein drink (e.g. Slim-Fast , Multan or Almased ), which is sold in pharmacies, is consumed . The preparations consist of soy and milk protein. In this way, about 60 grams of protein are absorbed per day, which should prevent the otherwise inevitable breakdown of muscle protein during a fast. In addition, feelings of hunger should be avoided and the blood sugar level should be kept low. Markert promises that on this diet, up to 5 kilograms of pure body fat would be lost per week. The vegetable broth is said to provide antioxidants to fight free radicals , which, according to Markert, inhibit fat loss. It is also important to have a sports program during the two-week fasting phase in order to increase energy requirements.
Theory
According to Markert, the protein preparation has an influence on the hormone production of the thyroid gland , which is stimulated to produce more of the hormone triiodothyronine (T3). The result is the stimulation of the metabolism and the promotion of fat burning. With the Markert diet, the body's basal metabolic rate does not decrease, as is generally observed with fasting. Markert claims to be able to prove this effect through his own studies. The graphs published by him refute this assertion; the T3 concentration decreases continuously during fasting despite the protein preparation. An independent study also contradicts this theory.
In his calculations on weight loss through fat loss, Markert assumes a daily calorie requirement of 2,400 kilocalories; however, the actual need varies from person to person and is at least significantly lower for most women.
After the fasting phase, it is said to be possible to maintain the desired weight without any particular restrictions while eating, provided that the protein preparation is continued to be taken regularly. It ensures that the metabolism is kept at a high level.
The new Markert diet
Perhaps in response to strong criticism from nutritionists, Markert has now published The New Markert Diet . This is no longer a fasting diet, but a low calorie diet. In the morning and at noon, fruits and vegetables should be eaten as well as vegetable fats. 40 percent of the diet should consist of complex carbohydrates , 20 percent of protein. Dinner consists of a protein drink with iodine and carnitine . This way, about 1000 kilocalories are consumed per day. Exercise no longer plays a role in this diet.
criticism
With the original Markert diet, like after a fast, the yo-yo effect is almost inevitable, and with the new diet it is likely because of the low calorie intake. In addition, there are no scientific studies that prove that protein or diet has any influence on thyroid hormone production, with the exception of iodine intake. The metabolism is not stimulated by this diet, it is even slowed down significantly when fasting. In the initial phase of a diet, glucose is always broken down first. The Markert Diet also promotes a special product that is superfluous at least after the diet, as sufficient protein is already consumed with the usual mixed diet.
