It may seem harmful to restrict your body of food, however it’s actually a part of human nature—and comes with certain benefits. Nutritionists love the idea of intermittent fasting. It’s not technically a diet; it falls squarely into the “lifestyle change” category, plus it brings us back to our ancestral roots. While evidence proves that it can help you lose weight, you may be wondering how it actually does so. What happens to your body when you fast?
1. Your Insulin Lowers
Danielle Schaub, MS, RD, CDN, a registered dietitian at New York-Presbyterian/Weill Cornell Medical Center offers a quick biology lesson: after you eat, carbs are digested into sugars, then those sugars enter your bloodstream and trigger a release of insulin. Insulin’s job is to move sugar from the bloodstream to your cells. But insulin also blocks fat cells from releasing fat, which means your body can’t burn fat when insulin levels are high. It’s only when the sugar is relocated into the cells that insulin levels drop again.
