What Happens When You Go 18 hours Without Eating?

When you go 18 hours without eating, your body enters a fasted state. During this time, insulin levels drop, and the body starts burning stored fat for energy ( 15 ). Other changes in the body during an 18-hour fast may include increased release of growth hormone, upregulated cellular repair processes, and a decrease in inflammation. These changes might have numerous health benefits, including weight loss and improved metabolic health ( 20 ).

How Often Should You Do an 18 Hour Fast?

Ideally, an 18 hour fast should be done consistently, with a goal of following the schedule for at least five days a week. This consistency can help your body adapt to the fasting pattern and promote better results. However, one may also choose to do intermittent fasting with shorter or longer fasting periods, depending on individual goals and preferences. It’s essential to listen to your body and adjust as needed for optimal results. It’s also important to speak to your healthcare provider before starting a fasting regimen or making any major dietary changes.
