A new study has found that men are more attracted to heavier women during periods of higher than normal stress.
This is probably from cave man times when food could be very hard to come by.
The study had 81 men split in half, with one group going on a simulated job interview while the other half were allowed to just relax.
Then both groups looked at pictures of women, from really skinny to obese and were told to rate their attractiveness.
Neither group was very interested in women on either of the extremes but the stressed men tended to rate photos of average and overweight women higher than the skinny women.
The study's authors wrote:
"The experience of stress may lead to a general preference for more mature physical traits in a potential partner because such traits are associated with improved ability to handle environmental stress."
This is known as the Environmental Security Hypothesis.
What's funny is this isn't the first time that researchers have looked into this connection before.
We are all slaves to our biological impulses.
