Major trial examines sugar-free sweetened soft drinks

Key Points:

• A 104-week randomized controlled trial by the University of Liverpool found that non-nutritive sweetened (NNS) beverages, containing aspartame, acesulfame-K, and sucralose, are as effective as water for long-term weight management in adults with overweight or obesity.
• The SWITCH trial, involving 493 participants, showed equivalent weight loss between the NNS and water groups, sustained weight reduction over two years, and improvements in body composition and metabolic biomarkers without adverse effects on blood pressure or cholesterol.
• The study addressed concerns that NNS beverages might disrupt appetite regulation or cause metabolic harm, finding no evidence to support these claims.
• Funded by the American Beverage Association but independently conducted, the research provides long-term clinical evidence that challenges recent WHO guidance advising against non-sugar sweeteners for weight control.
• Researchers hope these findings will inform future public health policies and global guidelines, offering NNS beverages as a viable alternative to sugar-sweetened drinks for weight management.
