Authors’ conclusions: among free diet people, the intake of free sugars or sugar sweetened beverages is a determinant of body weight. The change in body fatness that occurs with modifying intake seems to be mediated via changes in energy intake, since isoenergetic exchange of sugars with other carbohydrates was not associated with weight change.
Reviewers’ conclusions: the intake of sugar sweetened food or beverages has been linked to obesity. This systematic review shows that sugar intake in adults is related to weight gain and sugar reduction to weight reduction. In children, an association between the intake of sugar sweetened beverages and obesity has been proven. This review supports the recommendation of reducing the intake of sugar sweetened foods and beverages.
