Can FUT2 help with Abnehmen?

Whether FUT2 can help with weight loss is not clearly supported by evidence. FUT2 (fucosyltransferase 2) determines secretor status and influences gut microbiota composition and vitamin B12 absorption. Some studies have found associations between FUT2 variants and BMI, but effect sizes are small and likely mediated through microbiome or B12 levels. Direct weight loss benefits from FUT2 are not established. The evidence is mostly mechanistic and associative. A DNA test can reveal your secretor status, but translating that into a weight loss strategy is speculative. Sustainable weight management depends on energy balance, diet quality, and lifestyle – FUT2 alone does not provide actionable guidance.
