  • Time-restricted eating can help overweight people shed some pounds and abdominal fat
  • People who limit their daily eating window to 10 hours consume fewer calories
  • The reduced caloric intake is likely a result of the limited eating window

Findings of a new study have revealed that eating during a specific window of time can help overweight people shed some pounds and abdominal fat. 

In a new study published in the journal Cell Metabolism, researchers involved 19 volunteers who were asked to limit their daily eating window to 10 hours and fast for 14 hours. The participants ate and exercised as normal, and drank water whenever they pleased.

After the three-month study period, researchers found that those who followed this time-restricted eating routine saw 3 percent reduction in body mass index (BMI), weight and  abdominal fat. 

Study researcher Pam Taub, a cardiologist at the University of California, San Diego’s School of Medicine, said that while the participants did not change what they eat, they consumed about 8.6 percent fewer calories. The researcher said that the reduced caloric intake is likely a result of the limited eating window. 

The researchers also found that time-restricted eating is not just effective for weight loss and reducing waistline. It is also beneficial to health. Many of the participants saw a reduction in their cholesterol levels and blood pressure, and 70 percent reported improvements in sleep quality. 

Taub explained what makes intermittent fasting effective for weight loss. 

“When you go into a fasting state, you start to deplete the glucose stores in your body and you start to use fat as your energy source,” Taub said. “You can enter a low-grade state of ketosis.”

The researchers are now conducting randomized, controlled clinical trial funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) to confirm the benefits of time-restricted eating in individuals with metabolic syndrome. 

“TRE [time-restricted eating] is a potentially powerful lifestyle intervention that can be added to standard medical practice to treat metabolic syndrome,” Taub and colleagues wrote.
