Medical research related to low-carbohydrate diets

Low-carbohydrate diets became a major weight loss and health maintenance trend during the late 1990s and early 2000s. While their popularity has waned recently from its peak, they remain popular. This diet trend has stirred major controversies in the medical and nutritional sciences communities and, as yet, there is not a general consensus on their efficacy or safety. As of 2008 the majority of the medical community remains generally opposed to these diets for long term health although there has been a recent softening of this opposition by some organizations.

This article summarizes a sampling of the studies and other research that exist related to low carbohydrate diets, including the efficacy of such diets on weight loss and their effects on other health aspects such as ketosis. It is not a comprehensive list of all relevant research.
