This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

This study is testing whether time-restricted eating—eating all your meals within a short 8-hour window each day—helps people maintain weight loss better than eating over a normal 11-hour period. After you lose weight through a calorie-controlled diet, you'll be randomly assigned to either stick with the shorter eating window or a longer one, and researchers will track how much weight you keep off over the following months.

Most people who lose weight regain much of it within a few months. This study is trying to find out whether this eating pattern can help prevent that weight regain and improve other health markers like insulin sensitivity and heart disease risk.

Do you qualify?

You likely qualify if…

you have a body mass index (BMI) between 30 and 45
your recent blood tests are normal or show only minor, non-serious abnormalities
you normally eat within an 11-hour window or longer at least 5 days per week
you are able to understand the study procedures and commit to participating
you are willing to eat all the foods provided during the study, regardless of which group you're assigned to

You likely don't qualify if…

you have been diagnosed with diabetes, heart disease, liver disease, kidney disease, or other serious health conditions that could be affected by this eating pattern
you are currently taking medications or supplements that affect your weight or appetite
you have lost more than 10% of your body weight in the past two years (unless you gained it all back)
you are pregnant, planning to become pregnant within two years, breastfeeding, or within 12 months of giving birth
you are in perimenopause (experiencing irregular periods or menopausal symptoms)

What participation looks like

First, you'll follow a calorie-controlled diet designed to help you lose 8–10% of your body weight over 12–16 weeks. Then you'll be randomly assigned to either eat all your meals within 8 hours per day or within an 11-hour window. You'll be followed and monitored for several months afterward to see how well you maintain your weight loss, with blood tests and check-ins to measure changes in your health.
