What this Trial Is About

Researchers are studying how eating watermelon, including its juice and rind, affects feelings of fullness, metabolism, bowel habits, gut bacteria, and weight management in both children and adults. The study aims to better understand these effects by comparing watermelon juice with another red juice. It is an interventional study involving generally healthy participants aged 10 to 55 years. Participants are randomly assigned to one of two groups: one group drinks 8 fluid ounces of red juice daily for eight weeks, while the other group drinks 8 fluid ounces of watermelon juice daily for the same period. These two types of juice are being compared to assess their impact on satiety and digestive health. During the study, researchers measure changes in participants' feelings of fullness and blood levels of glucose, insulin, and triglycerides at multiple time points after juice consumption. They also analyze changes in gut microbiome diversity from the start to the end of the eight weeks. Participants are monitored throughout to track these outcomes and any effects on weight and bowel habits. The total study duration per participant is eight weeks.
