Randomized Controlled Trial Comparative Study Clinical Trial
A low-carbohydrate, ketogenic diet versus a low-fat diet to treat obesity and hyperlipidemia: a randomized, controlled trial.
Low-carbohydrate diets remain popular despite a paucity of scientific evidence on their effectiveness. ⋯ Compared with a low-fat diet, a low-carbohydrate diet program had better participant retention and greater weight loss. During active weight loss, serum triglyceride levels decreased more and high-density lipoprotein cholesterol level increased more with the low-carbohydrate diet than with the low-fat diet.
