With jobs being cut and retirement accounts seemingly shrinking by the day, it's too bad our waistlines aren't dwindling, too. We can't rectify that cosmic injustice, but in this issue we aim to help you figure out the most effective, least expensive ways to stay trim and fit.
Though most Americans find themselves overweight by middle age, an enviable minority stay slim throughout their lives. Are those people just genetically gifted? Or do they, too, have to work at keeping down their weight?
To find out, the Consumer Reports National Research Center asked subscribers to Consumer Reports about their lifetime weight history and their eating, dieting, and exercising habits. And now we have our answer:
People who have never become overweight aren't sitting in recliners with a bowl of corn chips in their laps. In our group of always-slim respondents, a mere 3 percent reported that they never exercised and that they ate whatever they pleased. The eating and exercise habits of the vast majority of the always-slim group look surprisingly like those of people who have successfully lost weight and kept it off.
Both groups eat healthful foods such as fruits, vegetables, and whole grains and eschew excessive dietary fat; practice portion control; and exercise vigorously and regularly. The only advantage the always-slim have over the successful dieters is that those habits seem to come a bit more naturally to them.
"When we've compared people maintaining a weight loss with controls who've always had a normal weight, we've found that both groups are working hard at it; the maintainers are just working a little harder," says Suzanne Phelan, Ph.D., an assistant professor of kinesiology at California Polytechnic State University and co-investigator of the National Weight Control Registry, which tracks people who have successfully maintained a weight loss over time. For our respondents, that meant exercising a little more and eating with a bit more restraint than an always-thin person—plus using more monitoring strategies such as weighing themselves or keeping a food diary.
A total of 21,632 readers completed the 2007 survey. The always thin, who had never been overweight, comprised 16 percent of our sample. Successful losers made up an additional 15 percent. We defined that group as people who, at the time of the survey, weighed at least 10 percent less than they did at their heaviest, and had been at that lower weight for at least three years. Failed dieters, who said they would like to slim down yet still weighed at or near their lifetime high, were, sad to say, the largest group: 42 percent. (The remaining 27 percent of respondents, such as people who had lost weight more recently, didn't fit into any of the categories.)
An encouraging note: More than half of our successful losers reported shedding the weight themselves, without aid of a commercial diet program, a medical treatment, a book, or diet pills. That confirms what we found in our last large diet survey, in 2002, in which 83 percent of "superlosers"—people who'd lost at least 10 percent of their starting weight and kept it off for five years or more—had done it entirely on their own.
