With 40 people it’s still 4 3/4 pounds of meat per person, plus the bun and condiments. We used to watch MvF but the gluttony became rather off putting over time. He’s a funny, likable guy, hope he loves doing the show because it could be shortening his life.
According to Wikipedia:
No exact reason was given as to why Richman retired, other than moving on and wishing his audience farewell. Explaining the show's re-tooling to become "Man V. Food Nation", Scripps Networks chairman Ken Lowe cited concerns over ensuring Adam Richman's health if the show had continued in its previous format. Richman had since turned vegan, and reportedly lost about 60 pounds.
