Are you an Extrovert – someone who seems to be energized by others? Or are you an Introvert – who finds the energy from within? It’s been studied and proven that people tend to eat more, the more people that are in the group. Extroverts will find every reason to go out and socialize, finding that the more people there are with them, the more energy they receive. I don’t know of any studies that have been done to prove whether Extroverts tend to be heavier than Introverts. But it stands to reason that they could be because, let’s face it, socializing almost always seems to have food involved.
