This meta- analysis suggests that individuals carrying the homozygous FTO obesity-predisposing allele may lose more weight through diet/lifestyle interventions than noncarriers .
BACKGROUND Studies have suggested that the fat mass and obesity-associated ( FTO ) genotype is associated with individual variability in weight loss in response to diet/lifestyle interventions , but results are inconsistent .
OBJECTIVE We aim ed to provide a summary of the literature evaluating the relation between the FTO genotype and weight loss in response to diet/lifestyle interventions .
FTO Genotype and 2-Year Change in Body Composition and Fat Distribution in Response to Weight-Loss Diets
Recent evidence suggests that the fat mass and obesity-associated gene ( FTO ) genotype may interact with dietary intakes in relation to adiposity . We tested the effect of FTO variant on weight loss in response to 2-year diet interventions . FTO rs1558902 was genotyped in 742 obese adults who were r and omly assigned to one of four diets  differing in the proportions of fat , protein , and carbohydrate .  Body composition and fat distribution were measured by dual-energy x-ray absorptiometry and computed tomography . We found significant modification effects for intervention varying in dietary protein on 2-year changes in fat-free mass , whole body total percentage of fat mass , total adipose tissue mass , visceral adipose tissue mass , and superficial adipose tissue mass ( for all interactions , P < 0.05 ) . Carriers of the risk allele had a greater reduction in weight , body composition , and fat distribution in response to a high-protein diet , whereas an opposite genetic effect was observed on changes in fat distribution in response to a low-protein diet . Likewise , significant interaction patterns also were observed at 6 months . Our data suggest that a high-protein diet may be beneficial for weight loss and improvement of body composition and fat distribution in individuals with the risk allele of the FTO variant rs1558902
