ClinConnect Summary

This clinical trial is looking at how drinking water can help with weight control in older adults aged 50 and over who are overweight or obese. The study will compare three different groups: one group will drink 500 ml of water before each main meal while following a low-calorie diet; another group will drink 1500 ml of water throughout the day with the same low-calorie diet; and the third group will follow the low-calorie diet without specific instructions on water intake. Researchers will use smart water bottles to track how much and when participants drink water. They will also measure various indicators to see how well participants are sticking to the water guidelines and to understand how water intake might affect feelings of hunger and fullness.

To participate in this study, you need to be at least 50 years old, have a body mass index (BMI) of 25 or higher, and have maintained a stable weight for the last six months. You should also be willing to follow the study guidelines. However, this trial is not for everyone; for example, people who usually drink a lot of water, have uncontrolled high blood pressure, or certain medical conditions that require specific diets may not be eligible. Participants can expect to learn more about how water consumption might help with appetite and weight management, while also contributing to important research in this area.
