Researchers at Imperial College London have found that fiber is extremely useful when it comes to losing weight and eating a healthy diet.
Why?
Not the difficult digestible fibers themselves, but rather an intestinal degradation product – acetate – caused mice to eat less and lose weight significantly. Acetate in the brain ensures that an appetite-suppressing messenger substance is released, which means that the animals automatically eat less as soon as they get the messenger substance sprayed.

If this effect is also confirmed in humans, it would mean that fat people in the future could naturally and effectively lose weight – and "only" by fiber or by the messenger acetate! But what are dietary fiber?
Dietary fibers are largely indigestible dietary constituents, which occur predominantly in plant foods. A distinction is made between water-soluble and water-insoluble fiber.
Dietary fiber in the stomach increases the volume of food without increasing the energy content, which means that they swell in the stomach and thus contribute to a (fast) feeling of fullness.
Where can you find fiber?
– whole grains (also with the addition of bran)
– legumes (beans, lentils …)
– nuts (peanuts, hazelnuts, walnuts, almonds …)
– Cereal flakes (oatmeal, wheat flakes, spelled flakes …)
– Brown rice (rice with shell – no white rice)
– Fruit and vegetables
