Extending your overnight fast is known as time-restricted eating (TRE) and is based on research showing the multiple health benefits from having a slightly later breakfast and an earlier evening meal (and of course, no late night snack!). 

TRE is a very popular form of intermittent fasting and sometimes also known as 16:8 or 14:10.

16:8 is the more challenging version, involving fasting for 16 hours and only eating within an eight-hour window. But don’t worry if you can’t last for this amount of time. Anyone who manages an overnight fast of more than 12 hours is doing really well.

There have been numerous studies showing that extending your overnight fast and eating within a shortened daytime window can lower your blood pressure and cholesterol levels, help you lose weight, improve your sleep, cut your risk of developing Type 2 diabetes, and may even slow the rate at which the brain declines as we age.
