| [1]Losing weight is hard enough. Keeping it off is even harder. Now a new study by researchers at Penn State suggests that the techniques that work for losing weight aren't necessarily the same as those that help keep you slim. [2]First the researchers surveyed over 1,100 people who had achieved significant weight loss and maintained ( 维持) it. The researchers identified 36 weight-loss and weight- maintenance practices that at least 10% of the group used. [3]Then the researchers conducted a national telephone survey of overweight people who had tried to lose weight and keep it off with varying success: about 11% reported successfully losing weight, and 21% were able to maintain that loss for at least a year. [4] The survey found people who ____ did so by participating in weight loss programs, cutting back on sugar, eating healthy snacks, not skipping meals and participating in different types of exercise. [5]Still,say many nutrition and obesity experts. The basic principles of weight loss and maintenance are the same; you have to eat a healthy diet and increase your exercise. People who lose weight and keep it off tend to eat significantly healthier foods and do a lot more exercise than the average American. [6] But what may maintain between weight-loss and maintenance is a person's attitude; rather than focusing on actively losing weight in the short term. People have to start focusing on long-term, permanent lifestyle changes and behaviors, if they want to maintain the weight that's been lost. The key to success, experts agree, is motivation, not necessarily the particulars of your weight-loss program. |
