What role does LCT play in Abnehmen?

LCT encodes lactase, the enzyme that breaks down lactose in dairy. A genetic variant (LCT-13910 C/T) determines lactase persistence (ability to digest milk into adulthood). For weight loss, LCT is only indirectly relevant: individuals with lactose intolerance may avoid dairy, potentially reducing calorie intake but also risking calcium/vitamin D deficiency. Some studies suggest dairy consumption may support weight management due to satiety and protein content, but the effect is small and not directly linked to LCT genotype. Direct-to-consumer tests often include LCT, but its role in weight loss is weak and mostly mechanistic. Evidence: mechanistic/unclear. Safety: if you have lactose intolerance, avoid large dairy servings; otherwise, dairy can be part of a healthy diet.
