It stars Tom McGowan, Aaron Schwartz, Shaun Weiss, Tom Hodges, Leah Lail, Paul Feig, Kenan Thompson, David Bowe, Max Goldblatt, Robert Zalkind, Patrick LaBrecque, Jeffrey Tambor, Jerry Stiller, Anne Meara, and Ben Stiller (in a dual role), and follows a fat camp for kids that is taken over by a fitness entrepreneur as its campers work to overthrow him.

Though it was initially met with mixed reviews, it found a following on home video and cable TV airings and has since become a cult film.

Initially reluctant, Gerry meets enthusiastic camp counselor Pat, and befriends the other campers, who have smuggled in enough junk food for the entire summer.

Pat is replaced by the strict new counselor Lars and the campers endure a painful softball game against their more athletic, over-competitive rivals Camp MVP.

Josh returns to Camp Hope revealing that his lawyer father has threatened to sue Tony for kicking his son out without a refund.

They discover a secret food stash used by most of the camp, leading them to gain weight, and Tony forces the boys on a 20-mile hike, preparing to endanger their lives for the sake of fitness.

With Pat, Julie, and Tim on their side, the campers take back control of Camp Hope, tying up Lars in the woods with Tony's other counselors, and celebrating with a binge eating bonfire party.

"[12] In a positive review, Hal Hinson of The Washington Post wrote, "Make no mistake about it, Disney's 'Heavyweights' is the best movie about calorically challenged pubescent boys at summer camp ever made.

"[13] In 2012, on the release of the Blu-ray, critic Brian Ordorff gave the film a grade of "B" and wrote: "Time has been kind to the discarded fat camp movie, finding Heavyweights more digestible these days, after years spent processing the askew sense of humor shared by Apatow and Company.
