5 Amazing Health Benefits of Fasting You Need to Know

5 Scientifically Proven Benefits of Fasting

Have you ever wondered what happens when you fast? Here are five scientifically proven facts that might surprise you. First things first, when you fast for 5 to 20 days, your body produces more circulating ketones. These act as an alternative energy source for both your body and brain, keeping you fueled when glucose levels drop. Prolonged fasting can lead to weight loss of 2-10%. But here’s the catch: About two-thirds of the weight you lose is lean mass, and only one-third comes from fat. Fasting can lower fasting glucose, insulin levels, and even insulin resistance. For those with normal blood sugar, it also helps reduce glycated hemoglobin, which is a marker for long-term glucose levels. Prolonged fasting can increase muscle protein breakdown, raising concerns about lean mass loss, especially during extended fasts. If you struggle with high blood pressure, fasting might help. Studies show that fasting consistently reduces systolic and diastolic blood pressure, which is great for heart health.
