After successfully treating over ten thousand patients, he popularized the Atkins diet 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 franchise, a business formed to provide products to those individuals on the diet, has 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 success and the company founded by Dr. Atkins in 1989, Atkins Nutritionals of Ronkonkoma, New York, filed for Chapter 11 bankruptcy in July of 2005, two years after the death of Dr. Atkins. The company re-emerged in January 2006, and the Atkins logo is still highly visible through licensed-proprietary branding for food products and related merchandise.
