In this News story, “Swedish health advisory body says too much carbohydrate, not fat, leads to obesity” (BMJ 2013;347:f6873, doi:10.1136/bmj.f6873), the headline and some of the text were incorrect. The report did not say that too much carbohydrate leads to obesity, as stated in the headline. It said that low carbohydrate diets were more beneficial for reducing obesity in the first six months of treatment, when compared with low fat diets, but made no difference at 12 months.

The report said that, in the longer term, “there are no differences in the effect on weight loss between advice on strict and moderate low carbohydrate diets, low fat diets, high protein diets, Mediterranean diets, diets aimed at achieving a low glycaemic load, or diets containing a high percentage of monounsaturated fats.” The report did not conclude that “the scientific evidence did not support a low fat diet.”

In addition, the report made few recommendations with regard to specific foods and did not say that “the consumption of pasta, potatoes, and white bread should be reduced.” We apologise for these errors.
