Description
Summary:Te Morenga and colleagues' review sheds some light on the confused literature regarding dietary sugars and body weight. 1 The authors acknowledge that the small change in body weight (~0.8 kg) attributed to alterations in sugar intake in the intervention trials cited probably results from changes in energy intake, rather than some characteristic unique to sugars. The authors seem to have used incorrect data from several studies, notably one large long term trial that showed a fall in body weight with a diet of 30% of calories from sugars compared with the control diet. 2 The heterogeneity of the interventions, the absence of a dose-response, and the admitted publication bias in the studies available for the meta-analysis further reduce confidence in the authors' conclusions.
