Zoe and Gregory Milton are a middle-aged couple who have gained weight over the years like everyone else. One day Zoe's friend Elaine who works for a radio station, pressures her to take part in a new weight loss competition programme called "Fat Chance", that give six couples the chance to win £50,000, if they lose the most weight.

This is funny and light-hearted but the story is too slight. It's the usual clichés about getting stuck in a chair, quips about terrible diets, useless exercise equipment and militant personal trainers. But it can't have all been bad because somehow they manage to lose a whole boulder between them, and they didn't even sign up to Weight Watchers or the like!

There is an unexpected amount of casual fat shaming, homophobia, racism, sexism and xenophobia, which put the rating down a notch. There really is no need. Also, absolutely no one writes detailed diary entries like that, especially if they say negative things about the people they know will read it. You can have dual POVs without such a gimmick.
