Researchers at the University of Liverpool followed 493 overweight and obese adults for two years, assigning half to drink water and the other half to consume beverages sweetened with low‑ or no‑calorie sweeteners such as aspartame, acesulfame potassium and sucralose. Participants also took part in a structured weight‑loss program.
When the study concluded, the diet‑drink group had shed an average of 10.6 pounds, compared with 8.2 pounds lost by the water group. The difference was not statistically significant, indicating that diet beverages can support weight loss just as well as water when paired with a disciplined diet plan.
State SNAP Restrictions and the Trump Administration’s Position
Florida and Indiana have recently prohibited the purchase of both regular and diet sodas with Supplemental Nutrition Assistance Program (SNAP) benefits. Florida’s ban, which took effect on April 20, lists drinks such as Diet Coke, Coke Zero and Diet Pepsi among the prohibited items. Indiana’s restrictions began on Jan. 1. Both states continue to allow sugary sports drinks like Gatorade and Powerade.
The U.S. Department of Agriculture has approved these state requests, and the Trump administration has publicly supported the measures, arguing that limiting soda purchases will improve the health of SNAP recipients. Each state determines the specific products that are barred, and the administration emphasizes that the policy is aimed at encouraging healthier choices without cutting essential nutrition.
Study Context and Limitations
The Liverpool trial did not compare diet soda with regular soda, nor did it evaluate whether SNAP restrictions directly improve health outcomes. Participants attended weekly weight‑loss meetings for the first 12 weeks, then monthly sessions for the remaining 40 weeks, and could opt to continue for a second year without additional meetings. Only 220 of the original 493 participants completed the two‑year follow‑up, a factor the authors acknowledge limits the study’s generalizability.
Both groups in the study reduced sugar intake and saw waist‑line reductions, reinforcing the notion that low‑calorie sweeteners can be part of a successful weight‑loss strategy when combined with broader dietary changes. The World Health Organization’s 2023 guidance warned that evidence for long‑term body‑fat reduction from non‑sugar sweeteners remains inconclusive, but it qualified the recommendation as conditional, noting that individual health conditions and patterns of sweetener use may affect outcomes.
Industry Funding and Oversight
The trial was published in the British Journal of Nutrition and received funding from the American Beverage Association. The association did not design, conduct, analyze, or interpret the study, though it reviewed the manuscript before publication. The Food and Drug Administration continues to affirm that approved sweeteners are safe for human consumption.
Implications for Families and Communities
For families relying on SNAP benefits, the study offers reassurance that choosing diet beverages does not compromise weight‑loss goals. At the same time, the Trump administration’s endorsement of state soda bans aligns with a broader effort to promote healthier eating habits among low‑income households, reflecting a commitment to both personal liberty and the well‑being of traditional families.
While the research does not directly measure the impact of SNAP restrictions, it provides a scientific backdrop for policymakers who argue that limiting high‑calorie, low‑nutrient drinks can support public‑health objectives without infringing on individual choice.
