“The average lunch or dinner, and even some breakfasts, can run up to 800 calories or more, so by simply substituting one 300-calorie meal for a usual meal, you can cut as many as 500 calories a day—and lose 1 pound in a week,” says Cathy Nonas, RD, a researcher at the New York Obesity Research Center.  But to make that easy, prepare a list of 300-calorie meals you can turn to after the holiday, or as soon as you need weight loss, recommends Nonas, author of Outwit Your Weight with Julia VanTine. You can start your own list by choosing any of the following 300-calorie meals. And no calorie counting needed! 300-Calorie Breakfasts
