Effectiveness and risks

There is weak evidence that the Atkins diet is more effective than behavioral counseling for weight loss at 6-12 months. The Atkins diet led to 0.1% to 2.9% more weight loss at one year compared to control groups which received behavioural counselling for weight loss. As with other commercial weight loss programs, the effect size is smaller over longer periods. Low-carb dieters' initial advantage in weight loss is likely a result of increased water loss, and that after the initial period, low-carbohydrate diets produce similar fat loss to other diets with similar caloric intake. Atkins did not publish any clinical data on his patients and has thus been criticized for making unsupported statements about health. Because of its high saturated fat content the Atkins diet may increase the risk of

Proposed mechanism

The diet was inspired by a low-carbohydrate approach published by Alfred W. Pennington, based on research Pennington did during World War II at DuPont. The Atkins diet is promoted with claims that carbohydrate restriction is the "key" to weight loss. In his early books such as ''Dr Atkins' New Diet Revolution'', Atkins made the controversial argument that the low-carbohydrate diet produces a metabolic advantage because "burning fat takes more calories so you expend more calories"; the Atkins diet was claimed to be "a high calorie way to stay thin forever". He cited one study in which he estimated this advantage to be 950 calories (4.0 MJ) per day. A review study published in ''Lancet'' concluded that there was no such metabolic advantage and dieters were simply eating fewer calories. Astrup stated, "The monotony and simplicity of the diet could inhibit appetite and food intake." David L. Katz has characterized Atkins' claim as nonsense. The idea of "metabolic advantage" of low-carbohydrate dieting has been falsified by experiment in a study of people following restricted-carbohydrate dieting.

Society and culture

Commercialization

Atkins Nutritionals was founded in 1989 by Atkins to promote the sale of Atkins-branded products. Following his death, waning popularity of the diet and a reduction in demand for Atkins products, Atkins Nutritionals, Inc. filed for Chapter 11 bankruptcy protection on July 31, 2005 citing losses of $340 million. It was subsequently purchased by North Castle Partners in 2007 and switched its emphasis to low-carb snacks."Atkins firm seeks financial help"
''BBC News''. August 1, 2005. In 2010, the company was acquired by Roark Capital Group. In 2017, Roark Capital Group announced that it would merge Atkins Nutritionals with Conyers Park Acquisition Corp to form a public company called Simply Good Foods.

'' magazine found that the sample menu from the Atkins diet was one of the top five most expensive to eat, of the ten plans Forbes analyzed. This was due to the inclusion of recipes with some high-cost ingredients such as lobster tails which were put in the book to demonstrate the variety of foods which could be consumed on the diet. The analysis showed the median average cost of the ten diets was approximately 50% higher, and Atkins 80% higher, than the American national average. The Atkins diet was less expensive than the Jenny Craig diet and more expensive than Weight Watchers.
