In the last hundred years there has been an absolute revolution in labor-saving devices. Many of these are wonderful, none more so probably than the indoor toilet that saves a trudge through cold and rain to the outhouse. But many do little more than save a bit of labor.... Individually, labor-saving devices don’t add up to much. But together they play an important role in the obesity problem....

Many factors of fairly recent development have led to the obesity epidemic. Food has become so cheap that not only can the poorest Americans be fat but indeed it appears the poorest Americans are the fattest. Labor-saving devices continue to proliferate. Television has more variety than ever and has now been joined by web-surfing as a major sedentary activity. And with any major introduction of something that affects our culture, there is a “shakeup” period in which we learn to adjust.

Consider, for example, automobiles. Even though they were much slower when they started to come into wide use about a century ago, their per capita accident and death rates were appalling by today’s standards. But over time we adjusted. Traffic laws were passed, roads were improved, myriad safety devices appeared. The result is that death rates have steadily declined and continue to do so.

Dieting usually fails in the long run, study finds

But is it better to have lost and gained than never to have lost at all?
“If dieting worked, there would be a bunch of skinny people walking around,” said obesity researcher Dr. David Katz, head of Yale University’s Prevention Research Center.

LOS ANGELES - Roberta Perry has tried it all to lose the pounds — organized diet programs, prescription pills, psychotherapy, even hypnosis.
Those efforts worked for a while for the Pennsylvania woman, but the weight inevitably crept back up. After years of yo-yo dieting, Perry realized it would take more than gimmicks to slim down.

“As much as I would like to have a magic bullet, I knew the only way to lose weight was eat less and exercise more,” said the 39-year-old public relations consultant.

Her experience is a common one. Researchers at the University of California, Los Angeles, examining 31 weight-loss studies found long-term dieting doesn’t keep the pounds off. While people can lose weight initially, many relapse and regain the weight they shed.
The findings confirm what many scientists have been saying all along: Losing weight is easy. Keeping it off is another story.

“If dieting worked, there would be a bunch of skinny people walking around,” said obesity researcher Dr. David Katz, head of Yale University’s Prevention Research Center, who did not participate in the latest study.

Since the 1970s, the ranks of overweight and obese Americans have risen with two-thirds of adults in that category. Obesity raises the risk of heart disease, diabetes and some cancers. Being overweight increases blood pressure and cholesterol levels which can lead to heart disease.

Many factors can conspire against successful weight reduction, health experts say. Diets can be boring and there’s always a temptation to return to old habits. Serial dieters may also become discouraged and give up when their weight plateaus. People who lose too much too soon don’t learn to make the overall lifestyle changes — eating healthier foods and exercising regularly — that are necessary to keep their weight stable.

“It’s just plain difficult to modify your diet and turn away from the pleasures of eating,” said Michael Goran, an obesity researcher at the University of Southern California. “We’re driven to eat.”

Few success stories

The UCLA researchers analyzed 31 diet studies that followed people two to five years after they went on diets. Between one-third and two-thirds gained back the weight they lost. A small number were able to successfully maintain their weight loss.

The UCLA study did not compare individual fad diets or organized weight-loss programs.

“We’re not saying don’t make some kind of effort,” said Traci Mann, the UCLA psychologist who led the study. “It means that people should be quite clear that a diet is a temporary fix.”

The study appeared in the April issue of American Psychologist, a publication of the American Psychological Association.

Perry, who owns a public relations firm in suburban Philadelphia, was an “emotional eater” who found comfort in food whenever she felt angry or depressed.
For the past 20 years, Perry tried all sorts of diets with mixed success. More recently, she decided to change her lifestyle and focus on lowering her cholesterol rather than obsessing about her weight.

The result: Perry, who is 5 feet 8 inches tall, has kept her weight steady for the past two years — 250 pounds from a high of 325 pounds. Although still obese, she is no longer considered morbidly obese.

“I would like to be healthier. I would like to be a little more toned,” she said. “But I’m not running out the door to join another program so I can lose weight and go back on that cycle.”

Risks of seesawing

It’s unclear whether repeatedly losing and gaining weight leads to health problems. But some studies have found a link between seesawing weight and problems such as high blood pressure, high cholesterol and gallbladder disease.
