Atkins Nutritionals Inc., the company that promoted low-carb eating into a national diet craze, filed for bankruptcy court protection Sunday, a company spokesman said.

Atkins has been hurt by waning popularity of its namesake diet, which focuses on eliminating carbohydrates such as bread and pasta to shed weight. The diet became one of the most popular in U.S. history, spawning a virtual cottage industry of low-carb regimens, but also drew criticism from experts for its focus on fatty foods and low fruit and vegetable consumption.
