Tom Watson, the deputy Labour leader, has said that his weight loss has led him to realise Britain must do more to tackle obesity.
Watson, 51, who has lost more than six stone on a nutritional regime that involves putting butter in his coffee, said he was motivated to take better care of his health after reading about Labour politicians who died early.
The West Bromwich East MP, first elected in 2001, said he was the thinnest he had been since entering the Commons.
Watson told ITVās Peston On Sunday: āI basically stopped taking sugar, refined sugar, and then I started walking 10,000 steps a day and walking up staircases and when a bit more weight came off I started to jog and cycle.
