Intermittent fasting, also known as time-restricted eating, involves extended periods between meals. Fasting triggers a stress response in the body, promoting the chances of survival. When you practice calorie restriction for a significant period, your body enters autophagy. Autophagy, or programmed cell death, plays a vital role in overall health by eliminating unnecessary "bad cells," facilitating healthy aging, and reducing the risk of diseases and cancers.
Studies have shown that skipping breakfast may have health benefits, including weight loss and reduced risk for metabolic diseases. Eating small meals throughout the day can lead to weight gain, as each time we eat, our body releases insulin which tells it to store fat. Intermittent fasting has also been found to potentially boost immunity, which is particularly important during the COVID-19 pandemic. There are different ways to practice intermittent fasting, including the 16:8 plan, where you eat during an 8-hour window and fast the remaining 16 hours, and the 24-hour fast, where you go one full day without eating.
