Excerpt

Since 1860, and more recently in 1972 low carbohydrate (low-carb) diets have been a strategy for weight loss.  Today, there continues to be an interest in low-carb approaches.  While all low carbohydrate approaches reduce the overall intake of carbohydrates, there is no clear consensus on what defines a low-carb diet.  There are three macronutrients—carbohydrates (4kcal/gm), fat (9kcal/gm) and protein (4kcal/gm) found in food.  Therefore, studies have defined low carbohydrate as a percent of daily macronutrient intake or total daily carbohydrate load.  We will define it here as: 1. Very low-carbohydrate (< 10% carbohydrates) or 20-50 gm/day. 2. Low-carbohydrate (<26% carbohydrates) or less than < 130 gm/day. 3. Moderate-carbohydrate (26-44%). 4. High-carbohydrate (45% or greater). For reference, the Institute of Medicine proposes Americans obtain 45-65% of calories from carbohydrates.[1]  This article will review the evidence and effectiveness of low-carb approaches in clinical medicine.
