To Diet or Not to Diet? (16x4)

Air date: Jan 30, 2014

Jonathan Maitland takes a look at the diet industry which is currently worth two billion pounds a year, yet ironically as a nation we just keep getting fatter. The weight loss industry is big business, but do these diets really work in the long term? As over half the nation resolves to lose weight this year, the programme looks at how we diet and what can be done to tip the scales in our favour.
