Intermittent fasting is an eating pattern that cycles between defined periods of eating and fasting, focusing not on what you eat but rather when. Popular approaches include the 16:8 method (fasting for 16 hours followed by an 8-hour eating window), the 5:2 approach (eating normally five days a week with reduced intake on two non-consecutive days), and alternate-day fasting. Each offers a flexible entry point depending on your lifestyle, making it one of the more accessible tools for supporting metabolic health without overhauling your entire relationship with food.
During fasting windows, the body shifts from burning glucose to drawing on stored fat for fuel, supporting cellular repair, sustained energy, and blood sugar balance. Over time, this metabolic shift may also reduce inflammation and activate autophagy, the body’s natural process of clearing out damaged cells and regenerating healthier ones. As with any wellness practice, experimenting to find what works for your body is all part of the journey.
