In Dr. Robert C. Atkins' original books, he makes it clear that the Induction Phase is an essential part of the Atkins Nutritional Approach (also known as The Atkins Diet). Now, Atkins materials are making statements such as the one above, indicating that the Induction Phase is not absolutely necessary. Is this because Induction seems to draw a lot of criticism from anti low-carb health professionals and other critics? I don't know, but I do have some thoughts on the whole question of Atkins Induction.
The Positive Side of Atkins Induction
This phase is meant to kick start the diet by forcing the body to convert from using carbohydrates for energy to using fat. It also tends to cause a large amount of weight loss. Untold numbers of people have found this to be helpful in starting them onto a new low-carb way of eating, and I am not going to be one to question their experience. Anything that helps people make a healthy change to healthy eating is wonderful in my book.
The Negative Side of Atkins Induction
On the other hand, it's clear to me that Induction isn't for everyone. My heart sinks every time I hear someone say that they tried Atkins but quit because it was "too hard." I think, "there goes someone else who could have been helped by cutting carbs but was turned off by an approach that is very restrictive." The fact is that most people don't need to cut carbs this much to get the benefits, and there is nothing wrong with starting the Atkins Diet at a higher carb level, as the quote at the top of this page attests.
Further, I think that the way Induction is described in some of the books is even more restrictive, and even confusing, than need be. For example, the books usually restrict vegetables to three cups of salad, or two cups of salad and one cup of non-starchy vegetables. Without further explanation, this could be unnecessarily low in carbohydrates, as one cup of shredded lettuce contains about half a gram of net carbs. The new instructions on the Atkins website say to get 12 to 15 grams of net carbs from vegetables, which is much clearer
