Sharon Osbourne, host of CBS daytime show The Talk, has been announced as ambassador for Atkins Nutritionals, saying 'I realised that Atkins is the best plan for me because my body - like many women my age - doesn't process sugar and refined carbs well.

In just two weeks, I am already 11 pounds lighter'. Osbourne will chronicle her weight loss journey online, contributing tips and advice for followers, as well as fronting a print, online and TV marketing campaign.
