Fasting: What Happens in Your Body?

Have you ever wondered what fasting does to your body? Lots of people are doing it to lose weight or for religious reasons. Scientists have found that fasting can change how your body uses sugar and fat. This is because fasting triggers lots of changes in your hormones, gut bacteria, and enzymes. Some of these changes depend on your sex hormones, fat-related hormones, growth hormones, insulin, and your gut microbiome. When you fast, your body starts to burn fat and releases free fatty acids (FFA) into your bloodstream. This is called lipolysis.

Scientists are now studying how fasting can help prevent or treat conditions like diabetes and obesity. They're looking at specific pathways that fasting affects to improve how your body works. This can help us understand how fasting might be used to keep us healthy.
