JHND have just accepted this paper. It supports the view that energy consumed from sugar-sweetened beverages has a greater obesogenic effect in children, than energy consumed from solid foods. The work isn’t yet available on Early View, but keep a look out for it in a few weeks. I will post the link once it is available.
Liquid versus solid energy intake in relation to body composition among Australian children

Background: The debate about whether energy consumed in liquid form is more obesogenic than energy consumed in solid form remains equivocal. We aimed to evaluate the effects of liquid versus solid energy intake and different beverage types on changes in childhood adiposity.
Methods: Our analyses included 8-year-old Australian children (n=158) participating in the Childhood Asthma Prevention Study (CAPS). Dietary information was collected using three 24hr recalls at age 9 years. Multivariate linear regression was used to evaluate the effects of liquid versus solid energy intake and different beverage types on changes in BMI z-score from ages 8 to 11.5 years (△BMIz8-11.5y) and percentage body fat at age 11.5 years (%BF11.5y). Substitution models were used to evaluate the effects of substituting other beverage types for sugar-sweetened beverages (SSB).
Results: Liquid energy intake (1 MJ/d) was more closely associated with both △BMIz8-11.5y (β=0.23, P=0.02) and %BF11.5y (β=2.31%, P=0.01) than solid energy intake (△BMIz8-11.5y: β=0.12, P=0.01 and %BF11.5y: β=0.80%, P=0.07). SSB consumption (100 g/d) was directly associated with △BMIz8-11.5y (β=0.08, P=0.02) and %BF11.5y (β=0.92%, P=0.004)，whereas diet drinks (100 g/d) were inversely associated with △BMIz8-11.5y (β=0.18, P=0.02). Substitution of 100 g SSB by 100 g water or diet drink, but not other beverages, was inversely associated with both △BMIz8-11.5y and %BF11.5y (P<0.01).
Conclusions: Our findings indicate that liquid energy is more obesogenic than solid energy. In particular, SSB, but not other beverage types, are a significant predictor of childhood adiposity and replacing SSB with water can have long-term beneficial effects on childhood adiposity.
