Summary
The goal of this clinical trial is to test whether replacing sugary sodas with unsweetened, flavored sparkling waters can reduce added sugar intake and improve health in Black/African American and Latine adolescents with obesity who prefer sweet-tasting beverages. The main questions it aims to answer are: * Does replacing sugary sodas with water change liking for sugary drinks, and water? * Do shifts in liking for sweetness lead to improved diet quality and cardiometabolic health? Researchers will compare replacing sugary sodas with one of three alternative beverages: unsweetened sparkling water, plain water, and beverages with gradually reduced sugar to determine which strategy is most effective. Participants will: * Replace sugary sodas with study drinks for 4 weeks * Complete taste tests to measure their liking for and sensory experience of sweetness over 8-weeks * Provide dietary recalls, body measurements, and blood samples over 8-weeks
