I think that the R moderator rating likely came from the News forum - which is NOT an Atkins support forum and which was the primary form the article is posted in. I did post the article in the Atkins support forum as a secondary forum because I felt that, support forum or not, this was important news to share with those who were using or considering the Atkins diet.
And, ol' grumptuous, I have personally done quite a bit of research on Atkins and other diets and, regardless of the source of the above post, I happen to believe that it and other serious criticisms of the Atkins diet are quite correct.
