Body mass as a result of psychological, lifestyle and genetic determinants. A pilot study involving overweight/obese and normal weight women in their early adulthood

Psychological and lifestyle factors, particularly overeating behaviors, were more strongly associated with increased body weight in women with the TT and AT variants of the FTO SNP rs-9939609 gene, highlighting the potential influence of genetic predisposition on eating habits and weight status in this population. Proper eating habits and high physical activity play an important role in preventing overweight and obesity regardless of the genotype that poses a potential risk of weight gain. The study's findings bring practical implications for health education and health psychology.
