Phase 1: Induction. In this strict phase, you cut out almost all carbohydrates from your diet, eating just 20 grams of net carbs a day, mainly from vegetables. Instead of getting 45 to 65 percent of your daily calories from carbohydrates, as recommended by most nutrition guidelines, you get only about 10 percent. "Foundation" vegetables, such as asparagus, broccoli, celery, cucumber, green beans and peppers, should account for 12 to 15 grams of your daily net carbs. 

For decades we’ve been told that fat is detrimental to our health. Meanwhile low-fat “diet” products, often full of sugar, have flooded supermarket shelves. This has likely been a major mistake, that coincided with the start of the obesity epidemic. While this doesn’t prove causation, it’s clear the low-fat message didn’t prevent the obesity increase, and it is possible it contributed.
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.[19] It was subsequently purchased by North Castle Partners in 2007 and switched its emphasis to low-carb snacks.[20] In 2010, the company was acquired by Roark Capital Group.[21] 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.[22]

If you have type 1, it's important to know that the best way to keep your blood sugar levels steady is to carb count rather than following a particular diet. And there is no strong evidence that following a low-carb diet is safe or beneficial, which is why we don’t recommend this diet for people with type 1 diabetes. But some people with type 1 have reported needing less insulin and losing weight from following a low-carb diet.
