Carl and Meatwad both need to lose weight, so Frylock makes a bet with Carl that Meatwad will lose less weight than Carl. Frylock tries to get Meatwad to exercize and eat healthy, but Shake keeps making delicious food around Meatwad. Carl is on the South Bronx Paradise diet which is where he can eat anything he wants as long as he keeps eating South Bronx Paradise candy bars. He starts losing weight at an amazing, then alarming, rate. Frylock decides to check out one of those bars, and he doesn't like what he finds.
