The Atkins diet is a low-carbohydrate fad diet devised by Robert Atkins in the 1970s, marketed with claims that carbohydrate restriction is crucial to weight loss and that the diet offered "a high calorie way to stay thin forever".
The diet became popular in the early 2000s, with Atkins' book becoming one of the top 50 best-selling books in history, and as many as 1 in 11 North American adults claiming to be following it. Atkins died in 2003 and in 2005 Atkins Nutritionals, Inc. filed for bankruptcy following substantial financial losses.
There is no strong evidence of the diet's effectiveness in achieving durable weight loss; it is unbalanced as it promotes unlimited consumption of protein and saturated fat, and it may increase the risk of heart disease.[1][2]
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.
