Do men’s eating habits change when they get into women’s society? This is what the researchers decided to find out. They chose to observe a pizzeria that works on the principle of "Eat as much as you want".

Men who ate lunch with women ate more than those who ate lunch with other men: on average, they consumed 93% more pizza and 86% more salad.

Looking at the subject from the perspective of evolutionary psychology, the researchers suggested that men were fattened to impress their companions. “Our observations of men who were ‘densely fed’ are reasonable to perceive in the context of evolution as ‘beautiful’,” she writes.

At the same time, the researchers found that women ate the same portions in both male and female society. However, in the male society, women still felt like they had eaten too much.
