Can HLA-DQ2 help with Abnehmen?

HLA-DQ2 is a genetic marker strongly linked to celiac disease, but there is no robust scientific evidence that it directly aids weight loss. In individuals with untreated celiac disease, a gluten-free diet often leads to weight gain due to improved intestinal absorption. Conversely, for people without celiac, a gluten-free diet is not an effective weight-loss strategy—it may even be less nutritious and more expensive. The evidence for HLA-DQ2 playing a role in weight management is weak and lacks controlled trials. Therefore, using HLA-DQ2 testing for weight loss is not supported by current science. Instead, focus on established methods: calorie balance, balanced nutrition, and physical activity. Consumer DNA tests often overclaim such associations.
