The 8-Hour Diet: A Quick Guide to Getting Started

Last updated: 26 October 2026

Hungry, tired and still not seeing results? Many diets fail because they are too hard to keep up, and the weight returns as soon as they end. The 8-Hour Diet focuses on when you eat rather than how little, which makes it far easier to stick with.

Where it comes from

The plan was created by David Zinczenko, author of The Abs Diet, and became one of America’s most popular diet plans after 2013.

The 8-Hour Diet in a nutshell

• Eat all your meals within an 8-hour window, such as 9am to 5pm or 11am to 7pm.
• During the other 16 hours, drink plain water or unsweetened tea.
• Follow it at least 3 days a week for gradual results, or every day for faster progress.

Why it works

During the 16 fasting hours, your body uses up the sugar (glycogen) stored in your liver and begins burning stored fat for fuel. Combined with more daily walking, this simple change in timing can make a real difference.

Extra support

To support your progress, many customers add SucoSlim, OxyPlus or Raspberry Ketone Plus+ to their routine. Check with your doctor first if you have any medical condition.
