Having a messy kitchen might actually cause your waistline to expand, finds a new study. Researchers recruited 100 women and then led them into a neat or messy kitchen where they were instructed to either write about a time they felt in control, or write about a time they felt out of control. There was also food placed around the kitchens, and participants were told they could eat as much as they pleased. The results showed that women who wrote about feeling out of control in the messy kitchen ate twice as many cookies as the women in the tidy kitchen. The environment didn’t have any impact on how much healthy food was consumed. Also, women in the messy kitchens who wrote about a time they felt in control ate fewer cookies than those who wrote about feeling out of control in the same environment.
