Read our Obesity research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether time-restricted eating — a way of eating where you consume all your meals and snacks within a shorter window of time each day — can improve heart health and metabolic function in people with obesity and prediabetes. The study will compare people who eat within a 9-hour window to those who eat within a 14-hour window over 12 weeks. Researchers want to understand whether this eating pattern helps your body use insulin better and reduces your risk of heart disease.
Most people with obesity and prediabetes are at higher risk for heart disease and type 2 diabetes. Animal studies suggest that eating within a shorter time window may help the body's metabolism work better, but we don't yet know if this benefit also happens in people — that's what this study aims to find out.

If you join this study, you will be randomly assigned to either eat all your meals within a 9-hour window or a 14-hour window each day for 12 weeks. You will keep your normal diet and calorie intake — the only thing changing is *when* you eat. During the study, you'll have visits where researchers will take blood samples, measure your metabolism, and check how your body responds to the eating schedule. The study is designed to see if the shorter eating window helps your body use insulin better and improves heart health markers.
