- What it's testing
- The study will see whether time‑restricted eating changes blood pressure, cholesterol, triglycerides, waist size, and blood sugar in people with metabolic syndrome.
- Who it's for
- Adults who have metabolic syndrome and normally eat for more than 12 hours a day.
- What's involved
- Participants will be randomly assigned to either continue their usual diet or to eat only during a set time window each day, while their health measures are monitored.
- Time commitment
- The trial lasts several months, with regular clinic visits and health check‑ups to track changes.
