What does fasting do to your body?

The Science of Fasting This helps drive blood sugar and insulin levels down, reducing your likelihood of gaining weight and developing diabetes or heart disease. Intermittent fasting also increases the release of human growth hormone, which regulates your metabolism and preserves muscle mass while burning fat.

How long should you fast for your body?

How long you should fast depends on your goals, but for general health, starting with 12-16 hours daily (like 16:8) is great for beginners, promoting fat burning and cellular cleanup (autophagy). Longer fasts (24-72 hours) offer deeper benefits (insulin sensitivity, autophagy) but carry risks like electrolyte loss and should be done cautiously, ideally with guidance, as very long fasts can be dangerous or trigger fat storage if done improperly. Always listen to your body and consult a doctor if you have underlying conditions. 

What are the 5 benefits of fasting?

What happens to your body during fasting?

Essentially, fasting cleanses our body of toxins and forces cells into processes that are not usually stimulated when a steady stream of fuel from food is always present. When we fast, the body does not have its usual access to glucose, forcing the cells to resort to other means and materials to produce energy.

Why are doctors against intermittent fasting?

The 5 stages of fasting track your body's metabolic shift from using food glucose to burning stored fat, typically moving from the Fed State (0-4 hrs) into the Postabsorptive Phase (glycogen use), then entering Fat Burning/Ketosis (12-24+ hrs), followed by Gluconeogenesis (making glucose from non-carb sources), and finally reaching deeper states with potential benefits like Autophagy (cellular cleanup) and Protein Conservation in prolonged fasts, though definitions vary slightly by source. 

What are the signs that fasting is working?
