Study Background
Having overweight and diabetes or prediabetes is associated with eating during more hours of the day, especially late in the day. This might lead to high blood sugar, low metabolism, and poor sleep.

Decreasing calories might be effective for short-term weight loss, but it’s hard to maintain over a long period of time and may not be the healthiest option.

Researchers are evaluating the effectiveness of time-restricted eating, a form of intermittent fasting, for people who have been diagnosed with diabetes or prediabetes and have overweight.

Your involvement may lead to an improvement in your lifestyle and overall health.
