The metabolism is the basis of all essential processes in our body.

Metabolism includes basically all biological and chemical processes occurring within our cells. The metabolism processes are needed for the preservation of the body, for energy generation and for the conservation of body functions. Short-chain fatty acids have an influence on several metabolic processes.

It is well-known that the intake of larger amounts of non-digestible plant fibers (i. e. high-fiber diet) favors weight loss and normalizes the metabolism of sugar. The blood glucose level decreases. At first, this seems somewhat contradictory because short-chain fatty acids, especially propionic acid, are used in the liver for glucosene generation (gluconeogenesis). But especially the propionic acid has a central role in this blood sugar regulation and influences favorably the metabolism of sugars at various points. In the intestine, for example, propionic acid is involved in the formation of sugar. This regulates the dietary intake and the sugar content, so we feel less desire for sweetness and the feeling of satiety is obtained faster. Specific cells of the pancreas (beta cells) can produce more insulin by short-chain fatty acids. Insulin is a hormone that reduces our sugar levels. A high insulin level also provides a stronger sense of satiety. Thus, short chain fatty acids affect our appetite.

Insulin is not the only hormone that can be increased through short-chain fatty acids. The release of gut hormones GLP-1 (glucagon-like peptide 1) and PYY (peptide-YY) is also increased. This has the effect that the sugar content is influenced positively, the stomach emptying is delayed and a feeling of satiety is obtained. The hormone PYY also has an appetite reducing effect. Short-chain fatty acids also use fats that do not need to be stored in the liver (fatty liver). In addition, the new formation of further fats, called triglycerides is reduced. These triglycerides are considered unfavorable and can lead to cardiovascular diseases. Furthermore, there are important effects for the immune system and general intestinal health.
