Fat binder diet: How it works!

With the fat binder diet , you take chitosan in the form of ready-made preparations. This prevents the body from absorbing and utilizing fats from food. Read here how effective the fat binder diet is and what health risks it poses.

Fat binder diet – How it works

On the fat binder diet, you ingest chitosan (polyglucosamine). It is offered as a fat binder in the form of ready-to-use oral preparations. The substance is obtained from the shells of crabs, lobsters and shrimps and is an indigestible fiber for the body. On its way through the intestines, chitosan binds dietary fats so that these are not absorbed but excreted.

Benefits of the fat binder diet

By inhibiting fat absorption, you can eat a high-fat meal occasionally and without a guilty conscience , even while on a diet .

Chitosan can also lower LDL cholesterol and blood pressure.

Disadvantages of the fat binder diet

The fat binder diet has some disadvantages and risks for the body:

  • No change in diet.
  • The body does not only get calories from dietary fat, but above all from carbohydrates. In principle, weight loss worth mentioning with fat binders is only possible if you generally eat with fewer calories and also do sports .
  • Chitosan also interferes with the absorption of essential fatty acids and fat-soluble vitamins . To prevent a deficiency, the fat binder should not be taken with every meal.
  • The fat binder can impair the absorption of certain medicines (e.g. pills ). There should therefore be an interval of at least four hours between taking the fat binder and the medication.
  • The intake of chitosan means an increased fiber intake for the body. This can lead to digestive problems (constipation, flatulence, feeling of fullness) if not enough liquid is consumed throughout the day (at least two to three liters).


Although chitosan can actually reduce fat absorption, it is not suitable for reducing excess weight in the long term. Because the use of the fat binder does not change anything about the mostly unhealthy eating habits. It can also lead to an undersupply of essential fatty acids and fat-soluble vitamins.

Chitosan should not be taken in the following cases: severe diverticulosis, intestinal constriction, allergy to seafood (crabs …), pregnancy , lactation.
