The study, published in the journal PLoS ONE, reports that when men were placed in stressful situations, then asked to rate the attractiveness of women of varying body sizes, they tended to prefer beefier frames, compared with unstressed men whose tastes skewed thinner.
“This suggests that our body size preferences are not innate, but are flexible,” said study co-author Martin Tovée of Newcastle University in the U.K., in an email, noting that they may be influenced by our particular environment and resources.
Indeed, Tovée and colleague Viren Swami of the University of Westminster in London have previously found that men under trying conditions — like extreme hunger — tend to rate heavier women as more attractive.
So the heavier women should starve their men to keep them interested.
