(Wrong) ways to the desired weight - Without scientific proof no success?

Here are presented very different weight loss programs, which all have one thing in common: they are not (yet) scientifically proven. Sometimes it is with these diets, the belief that should move mountains, but often scientifically unasserted statements to spurs unsustainable (weight loss). But maybe someone can still find in this selection his own weight loss program, if it corresponds to a balanced diet.

The polymeal diet

This diet has only existed since 2004 and is therefore currently not sufficiently scientifically proven. On her menu are only foods that reduce the risk of heart disease. Allegedly this risk should decrease by 76% if this diet is followed, but the question remains whether the heart-protecting effects of the different foods can be individually added up as it was done here.

Haysche food combining

The food combining according to Dr. med. Hay has been around for 100 years. It follows two iron principles:

  • Protein and carbohydrates should be consumed separately
  • and the so-called acid-base balance in the body should be kept stable.

The theory of a hyperacidity-sick body can be found in many eating concepts. The body's own buffer systems should not be inexhaustible, which should lead in the long term to age-related muscle breakdown, osteoporosis and kidney stones. The separation of carbohydrates and proteins on the other hand is an outdated digestive theory and the promise that this diet can cure cancer and diabetes is dubious. Nevertheless, many people succeed with the food combining, because the recommended dishes are light and low in fat.


This diet is based on a combination of nutrients that "compensate for deficits in metabolism and mobilize existing fat reserves". What deficits are, remains unclear. There are also no vitamins and minerals (vital substances) that cause a "mobilization of fat reserves".

mono diets

Rice, potato, cabbage soup, vegetable, grape, fruit or pineapple diet are without exception compulsory diets that neither lead to a "turbo-burning fat" nor to a sustained weight loss. Initial pounds initially tumble primarily only by the loss of water. The one-sidedness of these diets then usually leads to food cravings, and the famous "yo-yo effect" is inevitably the result. The following diets are also partly or completely based on scientifically dubious promises:

  • Blood type diet
  • Metabolic Typing
  • Healthy weight loss with Schüßler salts
  • the color diet
  • one day diet
  • Slimming formula water
  • the rotation diet
  • Ideal weight without starvation
  • 7-day regimen grains
  • Slim and fit with dinner-canceling

High protein diets

Consuming a lot of protein (proteins) leads to some unfavorable changes in the metabolism. Diets such as the 3D diet, the Scarsdale diet, the Humplik cure, the Sears diet or the Max Planck diet (the institute of the same name expressly distances itself from this diet!) Are therefore unsuitable for people with kidney damage and gout. Even overweight people can get too high uric acid levels in these diets. An adverse effect on the blood sugar level is also suspected.

The promised weight loss takes place in the first few days mainly by the loss of water, then threaten by the usually too low calorie intake cravings, which lead to the termination of the diet. As a dietary diet, diets of this kind are in any case not recommended.

Psycho diets

Here is a mental slimming workout, because losing weight begins in the head! The scaffolding of psycho-diets is based on this insight, which today is the basis of almost all serious diets. However, autosuggestion, as used in NLP (Neuro-Linguistic Programming), Hypnotherapy and Autogenic Training should only be provided with professional (psychological) guidance.

In any case, "losing weight in the head" can not replace learning to change eating habits or regular exercise. Diets such as finally desired weight, mental slimming training or think slim! are therefore not recommended.

Diets derived from worldviews

It should be emphasized that it is not the worldviews with their nutritional systems that are scrutinized in weight loss programs of this kind, but the diets derived from them, such as Yin and Yang, the 5-element diet or the ideal weight with Ayurveda, because they are all not scientifically proven. While the concept of ideal weight with Ayurveda, despite some false statements can expect a weight loss, Yin and Yang and the 5-element diet in practice for a meaningful weight loss are not recommended.
