Lake Beewell is a camp for kids who want to lose weight. Chad Applewhite went there and lost thirty pounds, causing his epic diet. There is most likely a lake by the camp called Lake Beewell.
Chad ate a ton of salads and exercised a lot there. However, it didn't have a big effect on him at the end because all it took was one of Teddy Ortiz's brownies for him to get fat again.
