Furthermore, food conscientiousness was significantly negatively associated with weight gain, independent of general conscientiousness. Importantly, this effect was neither moderated by where students lived nor by their perceived access to healthy food, suggesting that food conscientiousness can prevent weight gain regardless of lifestyle.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>College undergraduates high (+1 <jats:italic>SD<\/jats:italic>) in food conscientiousness reported smaller weight gain (0.24 lbs) compared to those low (\u22121 <jats:italic>SD<\/jats:italic>) in food conscientiousness (3.93 lbs) during the first 2 months of a fall semester. The results suggest that food conscientiousness may be one of the psychological factors that shapes the extent to young adults gain
