Fad Diets: Why Do We Keep Falling for Fad Diets? (cont.)
"Or they just identify with the individuals who wrote the book," says Lisa Dorfman, RD, a dietician, mental health counselor, and spokeswoman for the American Dietetic Association.
For example, dieters may not think about whether a weight-loss plan touted by an attractive celebrity is healthy or logical. "They just like the way she looks and they'd like to look like her, too," Dorfman says.
Fad diets tend to appeal more to people's vanity than to their desire to stay healthy. The focus is on inches and pounds, not reducing the risk of diabetes or heart disease.
"They're more motivated by wanting to change the way they look than their health," Osborn says. "Maybe that's one of our problems as nutrition health professionals, because we so much focus on the long-term health consequences rather than how you look. We would prefer that people are comfortable with the way they look but they're more concerned with their health."
But in reality, bikini season or an upcoming high-school reunion may seem like more concrete and compelling reasons to slim down. And fad diets are always there, offering seemingly easy solutions.
What's more, you can't discount the warm-fuzzy factor when it comes to advice on weight loss, which causes so much anxiety and frustration for so many people. Authors of diet books often try to come off as nurturing and warm, while "official" advice from the government or professional organizations can seem clinical and cold.
Fads Are Nothing New
Although fad diets usually claim to be cutting-edge, most recycle ideas that have been knocking around for a while -- in some cases, more than a century.
"Claims that an author has a permanent solution or a new answer are pretty much bogus, because there's hardly a diet that shows up that hasn't been written about before," says Kelly Brownell, PhD, director of Yale University's Center for Eating and Weight Disorders.
But no matter how far-fetched, faddish ideas continue to appeal to dieters.
"People are very much intrigued by those things that seem to demystify the whole thing -- there's some magic hormone, or there's something in your blood type, you have to eat certain foods together because of how they're metabolized," Osborn says. "That has to be it. It couldn't be something as simple as I need to eat less and I need to exercise more."
Confusion about nutrition is the very reason fad diets exist. If we all knew how to eat, there would be no need for diet books.
