Hutch DaleyHutch Daley
, the protagonist; a 26-year old unemployed college graduate who still lives with his mother until she kicks him out and forces him to make his own money by becoming a counselor at Camp Vision.
- Basement-Dweller: Hutch. His mother spoiled him by letting him stay home without paying rent.
- Brilliant, but Lazy: Hutch graduated from college as a Psychology major but he has remained chronically unemployed and calls himself an "overeducated Millennial". In addition, he works out constantly and has a great active lifestyle but can't even keep a job as a trainer because he refuses to wake up at 8 A.M.
- Catchphrase: "I haven't had a sugar or non-alcoholic carb in years!" and "Fat camp!" when someone tries calling Camp Vision a fitness camp.
- A Degree in Useless: He majored in Psychology.
- Does Not Like Spam: He hates cookies, chocolate, bread, rice or anything else involving sugar and carbs (other than alcohol) because he blames them for having ruined his childhood and his chance to have dated his crush Jill Hendricks.
- Disappeared Dad: Hutch claims his dad left him as a child and started eating to fill in the emotional gap, becoming 240 pounds at only 5'5".
- Formerly Fat: He blames his dad leaving for his former emotional eating.
- Gold Digger: Hutch mooches off his best friend Dave to pay for his buffalo chicken salads and anticipates moving into Dave's house just because Dave has a paying job and a house, two things that Hutch lacks.
- Hypocrite: Hutch scolds his kids for not being physically active yet he himself is too lazy to find a job and move out of his mother's. Ironically, he still stays in shape by routinely working out.
- Insistent Terminology: Hutch keeps insisting on calling it fat camp while his co-workers and boss call it fitness camp.
- Jerk with a Heart of Gold: Hutch. He may be selfish and unnecessarily cruel to anybody (obese or not), but it's his moral lessons that end up pulling his kids together.
- Kick the Dog: Hutch can be insolent to nice people like Charlie for no reason.
- Lean and Mean: Hutch while having a good physique refuses to admit he's a petty freeloader with anger issues. He's chronically unemployed and shamelessly makes other people pay for his food, drinks and rent.
- Politically Incorrect Hero: Hutch is a straight-up misogynist and homophobe who started the "No homo!" chant. But he does change because of the Jerk-to-Nice-Guy Plot.
- Straw Misogynist: Hutch sees beautiful women as nothing more than sex objects and fat women as garbage.
- Trademark Favorite Food: Buffalo grilled chicken salads and alcoholic beverages, especially vodka sodas.
- Where Da White Women At?: Hutch has an affinity for slim Caucasian women but appears to have made up his mind by going for Abby. Back in his youth, he tried rapping to a white girl (Jill Hendricks) to win her love but she just walked away, which made Hutch blame his obesity for her leaving. Hutch either doesn't realize or secretly knows that there is a chance she also turned him down for ethnic reasons.
