This study is looking at how different ways of drinking water, combined with a healthy diet, can help older adults (age 50 and up) who are overweight or have obesity manage their weight. You would be randomly placed into one of three groups: drinking water before meals, drinking a set amount of water throughout the day, or just following a healthy diet without specific water instructions. All groups will follow a reduced-calorie diet plan (1200-1500 calories). The main goal is to see how much your body weight changes over time. To join, you need to be at least 50 years old, have a body mass index (BMI) of 25 or higher, and your weight should have been stable for the past six months. We are looking for 375 participants.

Study design

What's involved

You would receive counseling on a reduced-calorie diet plan. Smart water bottles will be used to track your water intake, and urine and blood samples will be taken to check water intake compliance.

Compensation

Not stated in the trial record.

Follow-up

Your body weight will be measured for 12 weeks during a weight loss phase, and then for 12 months after that phase.
