Dangers of 100% soup diet

Eating soup is good for your health and for the figure! But can we only eat vegetables in liquid form to lose weight? No ! Explanations from Dr Nina Cohen-Koubi, doctor-nutritionist.

Everyone has heard of the famous (and maligned!) Cabbage soup diet. There are several versions, but the principle always remains the same. Eat cabbage soup for 3 to 7 days, combining – or not – other foods. The soup diet is based on the same principle and consists of eating vegetables in liquid form for several days.

If the consumption of soup can be interesting when it is combined with other foods and allows a varied diet. The mono diet based on soups can have harmful consequences on health.


A woman between the ages of 18 and 40 needs 1,800 calories per day to be fit and healthy. A varied diet including proteins, carbohydrates, mineral salts, and vitamins. Is also necessary to ensure the proper functioning of the body.

Problem: The 100% soup diet provides only 500 to 1000 calories per day at most because the principle is to eat only vegetables. And while they are good for you, these foods are not enough to meet our needs!

The fact of eating only soup can thus create deficits in proteins, carbohydrates or even lipids.

Deficiencies are not without consequences, since proteins contain amino acids, at the origin of antibody synthesis, cell renewal, hormonal balance, or even enzymatic function, which allows good digestion.

Carbohydrates also have an essential function: they are the main source of energy for the brain. A low-carbohydrate diet, therefore, forces the body to draw on its reserves.

Which can have an impact on memory, cause concentration disorders or even be the cause of hypoglycemic discomfort.

Lipids, on the other hand, have an important role to play in the brain, since they come into play in the mechanism of transmission of signals between neurons.


If eating is essential for living, a notion of pleasure is obviously associated with it. And for meals to be moments of well-being, all the senses must be awakened, namely: sight, thanks to varied, colorful and well-prepared plates;
smell, thanks to the different scents that emanate from the plate;
the taste, thanks to the flavor of the foods found in the mouth;
touch, thanks to the texture and temperature of the food;
hearing, thanks to the sounds that food makes in the mouth during chewing.
With the 100% soup diet, the five senses are not very aroused and chewing is absent. This mechanism is however essential when we eat, because it is this which triggers digestion and sends signals of satiety to the brain. This redundant diet therefore ends up creating fatigue.

3)the yoyo effect and eating disorders

Adopting the 100% soup diet is to drastically reduce your calorie intake. Inevitably, frustration sets in and the lack of other foods is felt. So many changes in our eating habits, which promote the phenomenon of compensation, and therefore weight gain.

But the return of the pounds is not the greatest danger of the 100% soup diet. This diet can have even more serious consequences, and lead to eating disorders, in the form of reactive overeating, for example.

Soups: how to eat them well?

Extreme diets such as the 100% soup diet are strongly discouraged, especially as they do not take into account all the parameters responsible for weight gain as a whole. However, it is essential to treat the root of the overweight problem, which can have an emotional, emotional or even medicinal origin.

Soup can nevertheless be a real slimming ally if it is correctly integrated into our diet, because it has many benefits:

  • it is eaten hot, and helps us to warm up in winter;
  • hydrating, and can therefore constitute an alternative to plain water during a meal;
  • it is satiating and helps us to regulate our appetite.

To include soups in our diet, it is advisable to mix several vegetables, in order to take advantage of their different benefits, to make this soup a starter, in order to benefit from its satiating effect and, more generally, to adopt a balanced diet. .
