The thought alone of eating just 500 calories a day is enough to make any woman feel faint. But for two days a week that's exactly what the latest blockbuster diet from Britain recommends.
The Fast Diet, coauthored by London-based doctor Michael Mosley and writer Mimi Spencer, outlines a weight-loss plan that limits a woman's daily intake to 500 calories twice aweek (men get 600 calories) but allows dieters to eat whatever they want on the remaining five days.
"It's not really fasting. It's just a break from your normal routine," says Mosley, 56, who dropped 20 lbs. in three months on the plan. "It's not like an ordinary diet where you think about it all the time. The joy is that you get on with your ordinary life."
