17 diet shakes passed the eco-test.
Only two were rated “Good” and none received top marks.
Almost all of them had questionable ingredients.
Kassel – With the spring-like weather of the past few weeks, one or two people are probably already thinking about summer.
That's nice until you realize that your summer wardrobe has become a bit tight.
Some people may then resort to diet shakes that are supposed to help them lose weight after the hearty winter meals.
The good news: If you do it right, you can be successful.
A study by Ökotest recently confirmed this again.
The less good news: almost all of the tested products fail.
Mineral oil residues and, of all things, questionable sweeteners are particularly criticized.
Diet drinks in the Ökotest: Only two products scored “Good”.
The so-called formula products were tested, which are designed to replace one or two main meals a day.
The sobering result: out of 17 powders tested, eleven diet shakes failed, as
Ökotest
reports.
Only two received a grade of “Good”, two others received a “Satisfactory” rating, and another two barely got through with a “Sufficient” rating.
Ökotest examined 17 diet drinks.
Only two test products came out well.
Controversial sweeteners and mineral oil residues were often the problem.

Also noteworthy: the test winners were among the cheapest products for individual meals, although similarly inexpensive products can also be found at the other end of the test spectrum.

Ökotest takes a look at diet drinks - even the test winners are not free from defects
The diet shakes were examined for their strict legal requirements, their ingredients and instructions for use.
Both the composition and the declaration of the products are regulated by the EU.
All test products complied with the composition requirements; during the declaration, the testers found anomalies in many products.

Even the test winners were not free from defects.
There were therefore deductions for the use of controversial sweeteners.
The Doppelherz diet shake tested was also not free of errors in its product declaration according to the standards of the European Health Claims Regulation.
Controversial sweeteners and mineral oil residues were the main problems with the test products
However, the testers found mineral oil residues to be much more problematic, and slight traces of these were detected in the test winners.
Only two products were free of the questionable residues.
All other test products fluctuated between elevated and strongly elevated values.
In seven products, the content of saturated mineral oil hydrocarbons was so high that it reduced the rating by four grades.
The health effects of some of these mineral oil substances are still unclear; in animal experiments they have caused organ damage.
They can accumulate in human fatty tissue, liver, spleen and lymph nodes.

Ökotest shows: Diet drinks can help you lose weight - but only at the beginning
The testers also consider the marketing and application instructions of some products to be questionable.
The phrase “meal for weight control” is therefore misleading because the diet shakes are only a substitute and not a real meal.
According to experts, you can lose weight successfully with diet drinks.
But: “It is important to make sure to permanently change your eating habits,” emphasizes Professor Hans Hauner from the Technical University of Munich.
According to experts, the form products should only replace a maximum of two main meals in the initial phase to lose weight.
Then the use should be reduced to one shake per day and at the same time the diet should be changed to a healthier and lower calorie one.
According to Hauner, the regular meal should be a plant-based diet with lots of whole grains.
Anyone who rewards themselves with kebab or pizza in addition to two shakes will have little success in losing weight.
“Diet drinks help you get started on losing weight.
They do not replace switching to a healthy diet,” explains Birgit Hinsch, ecotrophologist at Ökotest.
Some test products therefore provided the replacement of three main meals.
The drinks are unsuitable for minors and pregnant and breastfeeding women.
