Road to desired weight-No success without scientific proof?

Here, very different interrogation programs are presented, all of which have one thing in common: They are not (yet) scientifically proven. Sometimes in these diets it is the belief that is supposed to move mountains, but often scientifically unproven statements are intended to encourage untenable (perceptual) achievements. But perhaps someone in this selection can still find their own individual program of acceptance if it corresponds to a balanced diet.

The Polymeal Diet

This diet has only been in existence since 2004 and is therefore not yet sufficiently scientifically proven. Only foods that are intended to reduce the risk of heart disease are on their meal plan. It is said that this risk is supposed to fall by 76% if this diet is adhered to, but the question remains whether the heart-protecting effects of the different foods can be added up individually in the way that has been done here.

Haysche separating food

The separating diet according to Dr. Hay has been around for 100 years. It follows two iron ground rules:

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

The theory of a body sick of acidification can be found in many eating concepts. The body’s buffer systems are apparently not supposed to be inexhaustible, which in the long term should lead to age-related muscle loss, osteoporosis and kidney stones. Separating carbohydrates and proteins, on the other hand, is an outdated digestive theory and the promise that this diet can cure cancer and diabetes is frivolous. Even so, many people have success with the separating diet because the recommended dishes are light and low in fat.


This diet is based on a combination of vital substances that should “compensate for deficits in metabolism and mobilize existing fat reserves .” What deficits these are remains unclear. Also, there are no vitamins and minerals (vital substances) that cause a “mobilization of fat reserves .”


Rice, potato, cabbage soup diet , vegetable, grape, fruit or pineapple diets are invariably forced diets that do not lead to a “turbo fat burn ” or persistent weight loss. Initial pounds initially purple mainly due to water loss. The one-sidedness of these diets then usually leads to hot hunger attacks, and the famous “yo-yo effect ” is inevitably the result. The following diets are also based partly or completely on scientifically frivolous promises:

  • Blood group diet
  • Metabolic Typing
  • Losing weight with bulckler salts
  • The Color Diet
  • One day diet
  • Slimming formula water
  • The rotation diet
  • Ideal weight without hunger cure
  • 7-day grain cure
  • Slim and fit with dinner cancelling

Protein-rich diets

Consuming a lot of protein (proteins) leads to some unfavorable changes in metabolism. Diets such as the 3Diet, the Scarsdale Diet, the Humplik cure, the Sears diet or the Max Planck Diet (the institute of the same name explicitly distances itself from this diet!) are therefore not suitable for individuals with kidney damage and gout. Even overweight ones can get too high a level of uric acid on these diets. An adverse effect on blood sugar levels is also suspected.

The promised weight loss takes place in the first few days mainly due to the loss of water, after which there is a risk of hot hunger attacks due to the usually too low calorie intake, which lead to the disaddition of the diet. Diets of this type are not recommended as permanent nutrition in any case.


Here, mental slimming training takes place, because losing weight starts in the head! This knowledge, which is the basis of almost all serious diets today, is based on the scaffolding of psychodiets. However, autosuggestion, as used in the NLP (neurolinguistic programming), hypnotherapy and autogenic training, should only be performed with professional (psychological) support.

In any case, the “weight losing in the head ” cannot replace learning a changed eating behavior or the also necessary regular movement. Diets like Finally wishweight, mental slimming training or thinking you slim down! It is therefore not recommended.

Diets derived from worldviews

It should be emphasized that it is not the worldviews with their dietary systems that are scrutinized in interrogation programs of this kind, but the diets derived from them, such as yin and yang, the 5-element diet or ideal weight with Ayurveda, because they All are not scientifically substantiated. While the concept of ideal weight with Ayurveda suggests weight loss despite some misstatements, Yin and Yang and the 5-element diet are not recommended in practice for meaningful weight loss.
