When it comes to dieting, losing weight fast holds some appeal. Maybe that’s why U.S. News & World Report has added a Fast Weight-Loss Diet category to its annual rankings of best diet plans. And one of the diets that comes out on top is the Health Management Resources (HMR) program.
    HMR is a meal replacement diet that can be done on your own at home or under medical supervision. Instead of made-at-home meals, dieters can order low-calorie milk, soups, nutrition bars and multigrain cereal.
    The U.S. News reviewers say the plus side to the HMR diet is its quick-start option and the convenience of having meals delivered to you. The down side is "the milk lacks variety," and it’s tough to eat out while on this diet.
    "A common misunderstanding is that losing weight quickly is not healthy, not sustainable, and will just lead to future weight re-gain," wrote Carol Addy, the chief medical officer at HMR, in a release. But she says, to the contrary, "numerous studies demonstrate that following a lifestyle change program which promotes fast initial weight loss can result in better long-term success."
