\n\tIf you\u2019ve been forcing down plain water<\/a> to drop a few pounds when you really just want a Diet Coke (there\u2019s nothing quite <\/em>as refreshing as a mid-day ice-cold \u201cfridge cig<\/a>\u201d), science has some potentially good news for you.<\/p>\n

\n\tAccording to a University of Liverpool study published in the British Journal of Nutrition<\/em><\/a>, diet drinks and water performed similarly for long-term weight management. But before we declare diet soda the \u201cnew water,\u201d let\u2019s look at the facts.<\/p>\n

\n\t\tWhat Did the Study Find?\t<\/h2>\n

\n\tResearchers randomly assigned 493 adults with overweight or obesity to drink at least two daily servings of either water or non-nutritive sweetened drinks \u2014 like diet colas and sweetened flavored waters. Everyone also participated in a behavioral weight-management program, with weekly meetings initially, then monthly meetings through the first year. The second year was an optional extension without those sessions.<\/p>\n

\t\t\t\t\tWeight-Loss Drugs for Kids Under 10? Here\u2019s What the WHO Thinks\t\t<\/p>\n

<\/span><\/p><\/div>\n

\t\t<\/a><\/p>\n<\/article>\n

\t
\n<\/section>\n<\/p>\n

\n\tAmong the 220 participants who completed the two-year follow-up, water drinkers maintained an average weight loss<\/a> of about 8.2 pounds, while the diet-drink group maintained about 10.6 pounds. The difference wasn\u2019t statistically significant. Analyses estimating missing participants\u2019 results also found no significant difference.<\/p>\n

\n\tThat\u2019s encouraging, but it doesn\u2019t mean either beverage caused the weight loss. These people were also participating in a program that included dietary advice and encouragement to increase physical activity.<\/p>\n

\n\t\tHere\u2019s Why I\u2019m Skeptical\t<\/h2>\n

\n\tThe study was funded by the American Beverage Association. (Something I\u2019d like to know before celebrating the results.) The association also funded medical-writing assistance, and a representative had an opportunity to review the manuscript. The authors say the funder wasn\u2019t involved in the trial\u2019s design, conduct, analysis, or interpretation, and that final content decisions were theirs.<\/p>\n

\n\tIndustry funding doesn\u2019t automatically make the finding wrong, but it deserves disclosure (which they provided), especially when the finding concerns the products the industry sells.<\/p>\n

\n\tThen there\u2019s the follow-up: 493 people started, but only 220 completed the two-year assessment. The researchers acknowledged that the low completion rate was a limitation.<\/p>\n

\n\t\tSo, Are Diet Drinks Healthy?\t<\/h2>\n

\n\tThat\u2019s a different question. This study suggests that diet drinks can fit into a weight-management program. It doesn\u2019t establish that they\u2019re as healthy as water or settle questions about long-term sweetener consumption<\/a>.<\/p>\n

\n\tOther research has also raised some concerns:<\/p>\n

\n
    \n
  • Cognitive health: <\/strong>A September 2025 study published in Neurology<\/em><\/a> found an association between consuming higher amounts of certain low- and no-calorie sweeteners across food and drinks and accelerated cognitive decline.<\/li>\n
  • Liver function: <\/strong>Research presented at a 2025 conference linked artificially sweetened drinks to an increased risk<\/a> of metabolic dysfunction-associated steatotic liver disease, a condition involving fat buildup in the liver.<\/li>\n<\/ul>\n<\/div>\n

    \n\tBoth studies<\/a> were observational, so neither proves that drinks or sweeteners caused those outcomes. That distinction matters here just as much as the funding disclosure does.<\/p>\n

    \n\tThe takeaway? Similar weight-loss results aren\u2019t a blanket health endorsement. Given the industry funding and how many people didn\u2019t finish the study, I\u2019m taking this one with a grain of salt.<\/p>\n<\/p><\/div>\n
