It's so formulaic. Person(s) claims not to understand how they've put on so much weight/can't lose any weight. Person claims to consume 1500 calories a day. Person is then secretly filmed (although not that secretly filmed cos they know they're being filmed cos they're on the program) and eats plates of food the size of another person. All day long. Person is then shown the "secret footage" and person displays suitable surprise (why? they are being filmed for the program. And surely they know how and what they are eating even when they're not being filmed, unless they were drugged and taken to a kebab shop against their will.) Person then understands where they are going wrong (eating massive amounts of food) and decides not to eat massive amounts of food anymore.
Really?
Fuck off.
