What role does FTO play in Darmgesundheit?

The provided context contains no direct evidence for a specific role of the FTO gene in gut health. FTO (Fat Mass and Obesity Associated) is primarily known for its influence on body weight and appetite. Some studies suggest possible indirect links: FTO variants can increase obesity risk, and obesity in turn affects the gut microbiome and intestinal barrier. However, these connections are complex and not sufficiently proven to postulate a direct effect of FTO on gut health. Direct-to-consumer DNA tests like MyBody can identify FTO variants, but interpretation regarding gut health is speculative. No clinically relevant statements about gut health can be derived from this. Evidence: unclear. Sources: none in context.
