Fad Diets—Fact or Fiction

How many people suddenly realize that the wedding, class reunion, or other special event is just around the corner and want to make a drastic change in their appearance by losing weight? Some dieters are obsessed with the perfect number, either a size of clothing or a place on the scale. Almost every person will admit to being on at least one diet, and unfortunately, most will admit to multiple diets. This “yo-yo” dieting is a trend that lends to the overall opinion by health experts and dieters themselves that diets, especially fad diets simply do not work.

Most have probably heard of the Cabbage Soup Diet or the Grapefruit Diet or know someone determined to lose weight on the latest diet book craze, such as the South Beach Diet. Fad diets are usually associated with a quick fix, rather than a lifetime change in eating habits. Unfortunately, fad diet claims are often too good to be true, and while some people may actually have the wherewithal to stick to the restrictions and lose weight, many regain the weight plus add on more pounds. Focusing on or eliminating certain foods from daily intake can set a dieter up for nutritional deficiencies if the diet is followed for extended periods of time.

An extensive review of scientific literature was performed by the United States Department of Agriculture to evaluate success of fad diets. They found the key ingredient to weight loss is calorie restriction. Eating 1400-1500 calories per day resulted in weight loss, with or without exercise and regardless of the weight loss diet. This number of calories induces weight loss because more calories are burned than consumed.

Eating a balanced diet of “good” carbohydrates, protein, and fat will set up healthy eating habits that will help maintain a healthy weight and extend benefits beyond the restrictions of the diet. Good carbohydrates such as fruits, vegetables, and whole grains should total 5 to 7 servings per day and when looking at a plate should take up to two-thirds of the space on the plate. Space for protein and fats should be maintained at a minimum.

Maintaining portion control is also a mainstay of good eating habits. Serving size is required on every food purchased and will define calories per serving. Examples of common food servings include: 1 slice of whole-grain bread, 1⁄2 cup of cooked pasta, 1⁄2 cup cooked vegetable, 1⁄2 cup of fruit, and 1 chicken breast. For those who don’t like to measure, relating serving sizes to familiar objects will help some people manage serving sizes. For example, a serving of raw vegetables is roughly the size of a fist, a serving of pasta is about the size of a scoop of ice cream, a serving of grilled fish is like the size of a checkbook.

Other food management suggestions include using smaller plates and serving from the kitchen onto the plate rather than serving family style from the table, both suggestions decrease second servings. Put leftovers away quickly, in portion controlled servings. Never eat out of the bag or carton. When eating out, ask for half portions, share an entrée or dessert, or take 1⁄2 home for a later meal. Buffets are challenging so try to plan your portions by viewing the buffet prior to filling your plate.
