Fig. 2: The effect of high-sugar feeding on body weight and Energy intake.

Forrest plots depicting the effects of high-sugar feeding on (A) Body weight, (B) Energy intake. The effect is quantified as d, the difference between the mean of the treatment and control groups. Positive values indicate a higher mean in the sugar-fed groups compared to the control group (and vice versa). Overall estimates were determined by random‐effects meta‐analysis and species- and sugar-specific effects were determined by random-effects meta-regressions. Estimates for fat as a percentage of diet, fasting time, duration, and age diet was started, correspond to slopes from random‐effects meta‐regression. k is the number of effect sizes on which each estimate is based, and bars correspond to 95% confidence intervals.
