British soap star Jennifer Metcalfe is a brand ambassador for diet company LighterLife Fast, which includes following the 5:2 plan — where she only eats about 600 calories a day for two days a week — using LighterLife products.
Jennifer showed off her fit figure in a campaign for the brand and told the Daily Mail: "You're not deprived and your energy levels are still up. To know my body is getting everything it needs, even to go to the gym, that makes me feel good."
