Signs that the public’s enthusiasm for low-carb dieting is waning are everywhere.

Books like Dr. Atkins’ New Diet Revolution and The Zone, which monopolized bestseller lists for much of 2003, have quietly bowed out of the Top 10. And sales of the thousands of newly launched low-carb food products have stalled. It appears that for a growing number of people, the diets heralded by celebrities as the key to boundless energy and a bodacious bod have proven to be a massive disappointment.Mcleans
