Atkins Nutritional Approach
From Atkinspedia
The Atkins Nutritional Approach, popularly known as the Atkins Diet or just Atkins, is the most marketed and well-known of the low-carbohydrate diets. It was adopted by Dr. Robert Atkins (1930-2003) in the 1960's from a diet he read in the Journal of the American Medical Association and utilized to resolve his own overweight condition following medical school and graduate medical training. After successfully treating over ten thousand patients, he popularized the Atkins Nutritional Approach in a series of books, starting with Dr. Atkins' Diet Revolution in 1972. In his revised book, Dr. Atkins' New Diet Revolution, Atkins updated some of his ideas, but remained faithful to the original concepts.
The Atkins Brand (the business formed to provide products serving people on Atkins) had been highly successful due to the popularity of the diet, and is considered the iconic and driving entity of the larger "low-carb craze". However, various factors have led to its dwindling in success, and the company Atkins Nutritionals of Ronkonkoma, New York, founded by Dr. Atkins in 1989, filed for bankruptcy in July of 2005. The company emerged from bankruptcy on January 10, 2006. The Atkins logo is still highly visible through licensed-proprietary branding for food products and related merchandise.

Nature of the diet
The Atkins Diet represents a radical departure from prevailing theories. Atkins claimed there are two main unrecognized factors about Western eating habits, arguing firstly that the main cause of obesity is eating refined carbohydrates particularly sugar, flour, and high-fructose corn syrups; and secondly, that saturated fat is overrated as a nutritional problem, and that only trans fats from sources such as hydrogenated oils need to be avoided. Consequently, Dr. Atkins rejects the advice of the food pyramid, instead asserting that the tremendous increase in refined carbohydrates is responsible for the rise in metabolic disorders of the 20th century, and that the focus on the detrimental effects of dietary fat has actually contributed to the obesity problem by increasing the proportion of insulin-inducing foods in the diet.
Dr. Atkins argued that many eating disorders are the result of hyperinsulinism, or excessive secretion of insulin which comes through eating too many carbohydrates. According to Dr. Atkins, this causes food cravings and unstable blood sugar levels, which can cause mood swings, depression, and sleeping problems. He claimed that his diet stabilizes insulin and blood sugar levels, eliminating cravings and often reducing appetite.
While most of the emphasis in Atkins is on the diet, nutritional supplements and exercise are considered equally important elements.
Atkins involves restriction of the intake of carbohydrates in order to switch the body's metabolism from burning glucose to burning fat (chiefly, stored fat). This process (called lipolysis) begins when the body enters the state of ketosis as a consequence of running out of carbohydrates to burn. Ketosis is an entirely normal state (eg, between meals or associated with heavy exercise).
Atkins restricts net carbs, or carbs that have an effect on blood sugar. Net carbohydrates can be calculated from a food source by subtracting sugar alcohols and fiber (which are shown to have a negligible effect on blood sugar levels) from total carbohydrates. Sugar alcohols need to be treated with caution, because while they may be slower to convert to glucose, they can be a significant source of glycemic load and can stall weight loss. Fructose (eg, as found in many industrial sweeteners) also contributes to caloric intake, though outside of the glucose -- insulin control loop.
Preferred foods in all categories are whole, unprocessed foods with a low glycemic load.
Phases
There are four phases of the Atkins diet.
Misconceptions about the diet
Many people incorrectly believe that the Atkins Diet promotes eating unlimited amounts of fatty meats and cheeses. In fact, while certain foods are allowed in unlimited quantities (i.e., are limited only by appetite), the Atkins Diet is very specific in recommending lean meats, such as seafood and poultry. This is a key point of clarification that Dr. Atkins addressed in the more recent revisions of his book.
Some criticism of the diet seems to be based on a confusion between ketosis and ketoacidosis.
Another common misconception arises from confusion between the Induction Phase and rest of the diet. The first two weeks of the Atkins Diet are strict, with only 20g of carbohydrates permitted per day. The plan is clear that dieters should not ordinarily continue past the 2-week Induction Phase without slowly raising their daily carbohydrate count. Once the weight-loss goal is reached, carbohydrate levels are raised even further.
The Induction Phase is also known for its comparatively lower intake of dietary fiber, and this is often misconstrued as characteristic of the diet as a whole. It is often misstated that those on the diet do not consume enough vegetables and fruits. However those who follow it properly should not face this problem as even the Induction Phase allows for adequate amounts of dark green leafy vegetables, for example. If excess fiber is needed, the daily requirement can be met with Supplementation.
