July 16, 2008 - Both a low-carbohydrate diet or a Mediterranean-style diet may be "effective alternatives" to a low-fat diet, with more favorable effects on lipids and/or glycemic control, new research suggests [1]. The two-year study, which managed to keep almost 85% of the 322 study participants on one of the three diets for the entire period, offers the hope that weight-loss diets can be tailored to personal preferences, without sacrificing efficacy, researchers say. "Several recent one-year dietary studies have led the American Diabetes Association to state in January 2008 that low-carb diets should be considered for a maximum of one year," lead author on the study, Dr Iris Shai (Ben Gurion University of the Negev, Beer-Sheva, Israel), told heartwire . "The current two-year study suggests that one low-fat diet doesn't fit all, meaning that the old paradigm should be reconsidered." Shai and colleagues publish the results of the Dietary Intervention Randomized Controlled Trial (DIRECT) in the July 17, 2008 issue of the New England Journal of Medicine

Weight loss with a low-carbohydrate, Mediterranean, or low-fat diet.

N Engl J Med. 2008 Jul 17;359(3):229-41. PMID: 18635428 Conclusions Mediterranean and low-carbohydrate diets may be effective alternatives to low-fat diets. The more favorable effects on lipids (with the low-carbohydrate diet) and on glycemic control (with the Mediterranean diet) suggest that personal preferences and metabolic considerations might inform individualized tailoring of dietary interventions.
