The Claim
Theoretical substitution of sugar-sweetened beverages with low-calorie sweetened beverages or water is not significantly associated with changes in body weight or waist circumference in adults, as observed across five European cohort studies.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Replacing sugary drinks with diet drinks or water does not change body weight or waist size in adults over the long term.
See the scientific wording
Theoretical substitution of sugar-sweetened beverages with low-calorie sweetened beverages or water showed no significant association with changes in body weight or waist circumference in adults across five European cohort studies, indicating that replacing one beverage with another does not reliably alter long-term weight trajectories.
When people stop drinking sugary drinks, they naturally eat more food or drink other calories to make up for the lost energy, so their total calorie intake stays about the same. This keeps body weight and waist size from changing, even if they switch to diet drinks or water.
What the research says
1 studyScientists looked at what happened when people switched from sugary drinks to diet drinks or water, and found no consistent change in weight or waist size over many years—so swapping drinks doesn’t seem to help or hurt weight loss.
