What Is the 18/6 Intermittent Fasting Schedule?
The 18/6 intermittent fasting method involves fasting for 18 hours and eating within a 6-hour window. Unlike more restrictive regimens, the 18/6 schedule allows enough flexibility for most lifestyles while still delivering powerful health benefits. This method is ideal for those who are ready to progress beyond 16/8 fasting or seek more pronounced results.
How It Works
During the 18-hour fasting period, your body depletes glycogen stores and begins to burn fat for fuel — a state known as ketosis. This encourages metabolic efficiency and better blood sugar regulation. When the body doesn’t constantly digest food, it has time to focus on cellular repair processes, including autophagy.
Key Health Benefits of the 18/6 Fasting Plan
Enhanced Fat Burning
Fasting for 18 hours forces the body to tap into fat stores for energy, making this protocol extremely effective for boosting metabolism and fat loss. You’ll burn more body fat even at rest.
Improved Insulin Sensitivity
One of the most well-documented benefits of intermittent fasting is improved insulin sensitivity. This reduces the risk of type 2 diabetes and improves energy regulation throughout the day.
Supports Mental Clarity
During fasting, your brain experiences a boost in neurotrophic factors and ketones, which support mental clarity and focus. Many people report being more productive during their fasted hours.
Promotes Autophagy
Autophagy is the body's way of cleaning out damaged cells and regenerating newer, healthier ones. The 18-hour fasting window promotes autophagy, which has been linked to anti-aging benefits and disease prevention.
Reduces Inflammation
Chronic inflammation is at the root of many modern diseases. Fasting has been shown to significantly reduce inflammatory markers, supporting heart health and overall wellness.
Who Should Try the 18/6 Fasting Method?
This schedule is best suited for individuals who already have some experience with fasting (like 14/10 or 16/8) and want to push for deeper health results. If you’re looking to lose stubborn fat or improve metabolic health, this plan offers a powerful structure to help reach those goals.
