Carriers of the T allele of the rs7903146 TCF7L2 polymorphism experience significantly greater reductions in body fat mass compared to CC homozygotes when treated with carbohydrate-restricted diet alone.

If you are undergoing dietary treatment for blood sugar issues, your genetic makeup (specifically the TCF7L2 gene) may determine how much body fat you lose. Those with the T allele tend to lose significantly more fat than those with the CC genotype. This suggests that personalized dietary advice based on genetics could optimize fat loss outcomes.

In group of diet, T allele carriers of rs7903146 TCF7L2 were characterized with more decrease in fat mass compared with CC homozygotes (- 7.90 ± 9.46% vs. -1.54 ± 8.98%, p = 0.027).
