Scientists Tested Diet Drinks for 2 Years. The Results May Surprise You
Key Points:
- A two-year randomized trial by University of Liverpool researchers found no significant difference in long-term weight loss between adults consuming water and those drinking diet beverages with low- or no-calorie sweeteners.
- Both groups maintained weight loss, reduced waist and hip measurements, and improved metabolic health markers after program support ended, with average weight loss around 4.8 kg for the diet beverage group and 3.7 kg for the water group.
- The study found no evidence that non-nutritive sweeteners disrupted appetite regulation or caused metabolic harm, with participants consuming sweeteners within established safety limits.
- These findings challenge WHO's caution against non-sugar sweeteners for weight control and provide long-term clinical evidence supporting diet beverages as an effective alternative to sugary drinks.
- Funded by the American Beverage Association, the independent research aims to inform future public health policies and guidance on beverage choices in weight management.
