Query: This may be a dangerous diet.

As I read the book, a lot of it made sense. However, the low volume of vegetables allowed didn't sound healthy. Also for people who don't like a large volume of meat, the Atkins diet is a difficult diet. I was on Atkins 3 weeks and had a lot less energy and needed to sleep a lot more than normal. I got off of the diet after finding out a friend who had been on Atkins 2 months had to have gall bladder surgery. Similar but healthier diets are Sugarbusters! and the G-Index.
