The Facts on Fad Diets

 The Facts on Fad Diets

There is no shortage of diet plans that promise quick weight loss. But how do you know when a fad diet is potentially dangerous?

Weight loss veterans know that losing weight and keeping it off requires a long-term commitment, yet even savvy dieters can occasionally be tempted by the quick weight loss promised by fad diets. 

As each new “lose weight fast” gimmick comes along, some people forget about the negatives associated with most fad diets  from a lack of nutritional value to food restrictions that are hard to live with  while others might not know if the weight-loss plan they’re considering is a fad or a program that could be helpful over the long haul. Here’s how to tell a flash-in-the-pan plan from an effective one.

Beware Magical Claims and Passing Promises

“It seems to be human nature to be attracted to fad diets, which promise quick and easy results,” says Allen Knehans, PhD, chair of the department of nutritional sciences at Oklahoma University Health Sciences University in Oklahoma City. Weeding out fad diets takes a bit of effort because, Knehans acknowledges, “there is no standard definition of a fad diet.” Here are some of the red flags that indicate a weight-loss plan is an ineffective fad diet:

• The diet promises that you will lose weight fast or at an unrealistic pace. The claims sound too good to be true. The diet's recommendations are based on a single study or no research at all.
• The diet's recommendations seem extreme.
• Statements made about the diet are refuted by reputable scientific organizations.
• It refers to foods as “good” or “bad.”
• Personal testimonials are used to “sell” the diet.
• The fad diet involves crash dieting, or very intense reductions in eating and drinking.

“Fad diets are the parachute pants of nutrition,” explains nutritionist Judy Penta, BS, a certified holistic health counselor and personal trainer with Patients Medical in New York City. “Usually these diets are popular only for a short time — a season or at most a few years — then become unpopular or even laughable when the new fad comes along.”

Feeding The Popularity Fad Diets

Why do fad diets become the rage? A number of factors typically fuel their popularity, including:

Celebrity endorsements. Who doesn’t want to be as popular and slender as the latest starlet?

The promise of quick weight loss. In this age of instant everything, there’s a natural temptation to fall for a weight-loss plan that promises quick weight loss in only weeks rather than months.

The “elimination” mentality. The idea that cutting out certain foods will result in quick weight loss plays into popular beliefs about dieting. “Many of these diets promote elimination of one or multiple food groups for a set number of days or in very specific combinations with some sort of gimmick,” says Penta, adding that many people equate misery and deprivation with dieting and so are more willing to accept this type of weight-loss plan, at least for a brief while.

Peer pressure. If all your friends are following the fad, it’s tempting to join in.

Fad Diet Safety Questions

The most important question about any weight-loss plan is not whether it is effective, but whether it’s safe and healthy for you.

Many fad diets work for a short period of time, usually causing you to drop pounds due to possibly unhealthy calorie reduction or water weight loss. Occasionally you may learn a trick or two about adding healthy foods to your diet or maybe a new recipe that you enjoy.

“The fad diets succeed at jolting you from the grind of mindless snacking, eating junk food on the run, and all the calorie and fat-packed extras like whipped cream in the cappuccino, or grabbing a slice of pizza on the way home from work. Just making these lifestyle adjustments is usually enough to see some weight loss,” explains Penta.

However, while you are reaping the benefits of your new quick weight-loss plan, you have to consider its overall nutritional makeup. Unfortunately, many fad diets do not meet the nutritional needs of most people. Here are some signs that a fad diet is not healthy for you:

 Muscle cramps

Dizziness

Confusion

Fainting

Dehydration

Severe constipation or diarrhea

Mood changes

Constant hunger

People who are on medication or have chronic health concerns must be especially cautious with fad diets, says Penta, and should always talk to a doctor before trying any new diet. There are also some psychological consequences to fad dieting, Penta adds. The fact that the diet resulted in quick weight loss without meeting your nutritional needs can lead to regaining weight rapidly if you revert back to your old eating habits and, ultimately, to yo-yo dieting.

“The sad fact is that fad diets set the individual up for failure. When the diet fails, the dieters may blame themselves and develop a feeling of demoralization and hopelessness that they are unable to lose weight,” says Penta. This can make it harder to make the healthy changes needed for long-term weight loss.

Find Better Alternatives to Fad Diets

If you are concerned that a weight-loss plan could be a fad diet, do some research — look for the science behind the diet’s claims. A better solution is to work with a nutritionist or registered dietitian to create a realistic diet that will be effective for you.

“People should follow recommendations made by reputable organizations, such as the Dietary Guidelines for Americans, which are made by the U.S. Department of Agriculture and U.S. Department of Health and Human Services,” Knehans says. The reality of weight loss is that, in the long run, a slow and steady approach brings more lasting results than any quick weight-loss fad.
