It ’ s no secret that some of the resolutions that many of us vowed to pursue in the new year — eat healthy, lose weight, quit smoking, save more money — have already fallen by the wayside. Many of them are likely the same resolutions that we abandoned last January. And it’s a good thing for those who sell health club memberships, quit-smoking programs and other products that help us think we can improve our lives. Many gyms see new memberships double in January , making up for the third of their members who do not renew each year. And many who sign up in January will be no-shows by February. “If I try one quick fix and it doesn’t work, I may be more likely to try the next quick fix,” Lisa Lahey, who coaches executives how to sustain behavior change, told The Times . The Biggest Loser Resort at Fitness Ridge doesn’t offer any quick fixes, just a 12-hour schedule full of exercise, a 1 , 200-calories-a-day diet and a fee of $2000 a week. The resort teaches its clients that “weight management” is a combination of fitness, diet and emotional health. “Given my recent weight gain, and the fact that I was turning 50,” Jennifer Conlin wrote in The Times , “I wanted to start a program that would make 2012 the year I finally got in shape.” “ For years, the advice to the overweight people has been that we simply need to eat less and exercise more ,” Tara Parker-Pope wrote. “Whi l e there is truth to this guidance, it fails to take into account that the human body continues to fight against weight loss long after dieting has stopped. This translates into a sobering (令人清醒的) reality: once we become fat, most of us, despite our best efforts, will probably stay fat. ” Of course this revelation (揭示) , if proven true by further study, is not good news for the weight-loss industry. But chances are it won ’ t have much impact on the human tendency to resolve to go to the gym more and avoid chocolate cake when the clock strikes midnight on December 31.
