Low-carb diets did not show significant weight loss over a conventional diet after one year.

Some short term weight loss results were demonstrated through a low-carb diet versus a low-calorie, high-carbohydrate, low-fat (termed by them, Conventional) diet. However, after a year there was no significant weight loss improvement associated with the low-carb diet.

This study was not a comparison between a low-carb diet and a low-fat whole foods plant based diet. As well, the effect of the low-carbohydrate diet on functions such as renal and cardiovascular was not evaluated. Bone health, and exercise tolerance was also not part of this study. Many participants in both groups did not maintain compliance. They had an attrition rate of 41%.
