Population-wide fiscal measures, such as taxes on sugar-sweetened beverages and unhealthy foods, can reduce purchases of taxed items and prevent childhood obesity cases, though their immediate impact on population health outcomes is limited and requires sustained implementation.
Government taxes on sugary drinks and unhealthy foods can reduce their purchase, but these policies are often weakened by industry opposition. For individuals, this means these products may remain accessible, so personal choices remain critical.
ModerateSupportsMEDIUM confidence
In 2014, Mexico introduced a 10% tax on sugar-sweetened beverages and an 8% tax on non-essential energy dense foods... a study by Colchero et al. which showed a decline of 7.6% in purchases of taxed beverages after 2 years of implementing the plan, though effects on energy intake and diet quality remain unstudied [9].
Why this rating
Based on modeling and case studies (Mexico), but long-term health outcomes are unstudied.

More from this paper
- Energy-restricted diets result in modest long-term weight loss (approx. 3% maintained at 5 years) and high relapse rates (>80%) due to compensatory metabolic adaptations including increased hunger hormones (ghrelin), decreased satiety hormones (leptin, GLP-1, PYY), and reduced energy expenditure.Good
- High protein diets increase satiety and preserve fat-free mass during weight loss through increased anorexigenic hormones (GLP-1, PYY, CCK), decreased orexigenic hormones (ghrelin), and higher diet-induced thermogenesis, though long-term satiety benefits may diminish due to adaptation.Good
- Low carbohydrate diets induce rapid short-term weight loss partly through ketosis (suppressing appetite via ketone bodies) and diuresis (water loss from glycogen depletion), but may increase LDL cholesterol and reduce diet quality due to low fiber intake.Moderate
