The insoluble dietary fibre that makes up the basis of rye bran works as a bulking component: it absorbs water and swells in the stomach, creating a feeling of fullness. As a result, the feeling of satiety after a meal with added fibre lasts longer than after refined foods of the same volume.
This makes the product interesting for those who notice that they get hungry soon after breakfast or often reach for random snacks. Adding bran to kefir or porridge in the morning is a simple way to make your first meal more filling with only a small increase in calories.
It is important to understand that the product does not suppress appetite by itself and is not a weight-loss product. The feeling of fullness depends on the overall composition of your diet, portion size and individual characteristics. The product should be seen as an addition to a balanced diet, not a replacement for it.
