Watching Diners, Drive-ins and Dives.....Yummmmm!

I love this show! I want to take a driving tour of all these places that Guy Fieri visits!! I want to try Chicken and waffles and 1/2 pound corn dogs and real philly cheese steaks!! It would be fun to learn to make them, but I seriously want to travel and just try them one time.  By the way, how does he stay somewhat average in weight going to these places??  For that matter, how does Adam do Man vs. Food and not weigh over 400lbs??? He isn't thin by any means, but seriously, what must his labwork look like?? I love food, and if I could travel and eat like that, I would definitely have to travel in a custom made trailor to support my new found weight!! I wonder if they purge after the taping of their shows? Hmmmm. Any thoughts?
