Fasting for 14 hours a day has major health benefits.
Experts at King's College London have found that eating meals during a ten-hour window can lead to better sleep and decreased hunger.
Intermittent fasting is a popular weight loss method, but the new research is the largest trial to date to show it has a positive health impact that goes beyond weight.
Kate Bermingham PhD, from King's College London and ZOE, said: "This study adds to the growing body of evidence showing the importance of how you eat. The health impact of food is not just what you eat but the time at which you choose to consume your meals, and eating window is an important dietary behaviour that can be beneficial for health.
"These findings show that we don't need to be eating all the time. Many people will feel satiated and even lose weight if they restrict their food to a ten-hour window."
