``There's never been any denying that low-carbohydrate, high-protein diets such as Atkins do, absolutely, cause weight loss,'' she said. ``But do they hold up over time and can you stay on them over time?''

What a liar this woman is.

Actually, there's been nothing BUT denial that people lose weight on Atkins.

As for holding up over time, and staying on them, it's not the food that causes people to slide...it's the difficulty of finding low-carb foods out there! Just this week I went to three functions where no low-carb was available! Nothing but bread, pasta, rice, etc...I had to eat something!
