Energy balance

Diet and lifestyle interventions reduce waist circumference regardless of TCF7L2 genotype, though the genotype does not modify this specific outcome.

You do not need to worry about your TCF7L2 genotype when it comes to losing belly fat. Standard diet and lifestyle changes will reduce waist circumference for everyone, regardless of whether you carry the risk allele. Focus on sustainable energy balance and activity.
