Sisters Precious and Florence, from Sidcup, are the latest pair to come under the show's spotlight with their eating habits held up for scrutiny.

So why are they both putting on weight? They're convinced they're making the right choices with their food, but Florence's mega-carb portion sizes, Precious's love of a treat, and both sisters' devotion to fast food seem to suggest otherwise.
