“[Vegetarians] are advertising a particular lifestyle, that they are high-maintenance,” said Fisher. “Their needs require others to bend – even if their philosophy may be a healthy philosophy.”

In addition, Fisher said, men who are vegetarian may be perceived as being less “manly” – and that may go back to our caveman days.

“I think in a lot of cultures it would be considered less manly – men used to bring home the meat, they were the hunters,” said Fisher. “If you came in carrying a potato versus a hunk of gazelle, it made a difference. All gifts are not alike.”
