 the atkins diet, officially called the atkins nutritional approach, is a low-carbohydrate diet promoted by robert atkins from a research paper he read in the journal of the american medical association published by alfred w. pennington, titled "weight reduction", published in 1958. atkins used the study to resolve his own overweight condition. he later popularized the method in a series of books, starting with dr. atkins' diet revolution in 1972. in his second book, dr. atkins' new diet revolution (2002), he modified parts of the diet but did not alter the original concepts. the new atkins for a new you (2010) is based upon a broad array of information gained over the last decade not covered in previous editions, including nutrient-rich foods. the new atkins for a new you cookbook was released in 2011 by colette heimowitz to provide dieters with simple, low-carb recipes. ==nature of the diet== thumb|a balanced meal according to the atkins diet the diet involves limited consumption of carbohydrates to switch the body's metabolism from metabolizing glucose as energy over to converting stored body fat to energy. this process, called ketosis, begins when insulin levels are low; in normal humans, insulin is lowest when blood glucose levels are low (mostly before eating). reduced insulin levels induce lipolysis, which consumes fat to produce ketone bodies. on the other hand, caloric carbohydrates (for example, glucose or starch, the latter made of chains of glucose) affect the body by increasing blood sugar after consumption (in the treatment of diabetes, blood sugar levels are used.) fiber, because of its low digestibility, provides little or no food energy and does not significantly affect glucose and insulin levels. 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". he cited one study where he estimated this advantage to be 950 calories (4.0 mj) per day. a review study published in lancet'the lancet, volume 364, issue 9437, pages 897â899, 4 september 2004 concluded that there was no such metabolic advantage and dieters were simply eating fewer calories due to boredom. astrup stated, "the monotony and
