Implementing excise taxes on sugar-sweetened beverages (SSBs) reduces their consumption and leads to modest reductions in population-level obesity and BMI.

To reduce obesity rates at a population level, governments can implement excise taxes on sugar-sweetened beverages. Evidence suggests that as prices rise, consumption drops significantly (elasticity ~-1.3), leading to modest but measurable decreases in BMI and obesity prevalence, particularly among lower-income groups who are more price-sensitive.

ModerateSupportsMEDIUM confidence
This comprehensive literature review suggests that an increase in price of SSBs is associated with a decrease in consumption; and the higher the price increase, the greater the reduction in consumption... The few available studies suggest that higher prices of SSBs may lead to modest reductions in weight in the population.
