TV presenter Ruth Langsford and Strictly Come Dancing winner Darren Gough are fronting a joint initiative from Diabetes UK and Tesco Diets, aiming to turn the nation's weight loss into £100k for charity.

The lbs for £s campaign encourages people to join Tesco's online healthy eating plan, with the supermarket promising to donate £1 for every pound of weight dropped to Diabetes UK and the Diabetes Federation of Ireland.
