The phrases fad diet and food fad originally referred to idiosyncratic diets and eating patterns that promote short-term weight loss, usually with no concern for long-term weight maintenance, and enjoy temporary popularity. The term "food fad" may also be used with a positive connotation, namely, to describe the short term popularity among restaurants and consumers of an ingredient, dish, or preparation technique. ==Definition== A fad diet is an eating regime that focuses on a particular food or food group. They are often endorsed by celebrities or medical professionals who style themselves as "weight loss gurus" and profit from sales of branded products, books, and public speaking.〔 Fad diets attract people who want to lose weight quickly and easily and keep that weight off; this is not actually possible and while some people following fad diets may lose weight in the short term, the loss is generally not sustained. In 1974, the term was defined as three categories of food fads.〔McBean, Lois D. M.S., R.D. and Elwood W. Speckmann Ph.D. (1974). Food faddism: a challenge to nutritionists and dietitians. American Journal of Clinical Nutrition, Vol 27, 1071-1078.〕 # A particular food or food group is exaggerated and purported to cure specific diseases. # Foods are eliminated from an individual’s diet because they are viewed as harmful. # An emphasis is placed on eating certain foods to express a particular lifestyle. FamilyDoctor.org, a publication of the American Academy of Family Physicians, for example, proclaims that fad diets "typically don't result in long-term weight loss and they are usually not very healthy. In fact, some of these diets can actually be dangerous to your health."〔(【引用サイトリンク】 title=Nutrition for Weight Loss: What You Need to Know About Fad Diets )〕 They then offer a long list that includes low-carbohydrate diets in general and Atkins, the Zone diet and three others by name. One scientific study contradicts the website's assertions. A 2007 study published in the Journal of American Medicine concluded that overweight premenopausal women age 25 - 50 without any heart, renal, kidney, or diabetic disease on the Atkins diet lost more weight than those on specific low-fat diets after 12 months. The researchers concluded that low-carbohydrate diets are a "feasible alternative recommendation for weight loss."〔(JAMA )〕 However, this study did not compare the Atkins diet to calorie restriction diets. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fad diet」の詳細全文を読む スポンサード リンク
