I've only seen a couple of episodes of this, but it's so gratifying to see something that confirms all your prejudices. So often when someone is talking about their weight and they bemoan how they can't seem to lose it despite eating "basically nothing" in your head you're thinking YOU LYING SACK OF SUET, but you know that telling them it is physically impossible for someone over 100 kg to gain weight eating under 1,500 calories, so they must be miscounting, will immediately make you the bad guy in the room.
