    [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.
