If you want to know the sensation of being full 24 hours a day every day you go on a cruise. You can get food whenever you want. The Carnival ones have these self serve frozen yogurt machines you can use to your hearts content.
So you've stuffed yourself all day and you realize it's 7 pm. "Oh no, it's dinner time!", you say to yourself, "they serve the really fancy stuff then." So you begrudgingly haul your butt to the dinner hall and eat until your entire digestive system has no vacancy.
You wake up the next day rather full, not surprisingly, but that free frozen yogurt looks too good to pass up. You rinse and repeat.
While all this is going on, you do get to stop at a little town or two so you get to walk some of the food off before the cycle begins again.
