Understanding 6 Stages of Fasting! | Dr. Zee | डॉक्टर ज़ी

In this video I'm going to talk about six stages of fasting. This is what’s happening in the body during each stage of fasting. The six stages of fasting: Stage 1: 8-14 hours • Stable blood sugar levels • Using up stored sugar and sugar in the blood • At 10 hours—the muscles use about 50% glucose and 50% fat (you’re starting to transition to fat-burning) Stage 2: 14-24 hours • Starting to get into ketosis • Fewer cravings • More energy • Improved mood • Improved cognitive function Stage 3: 24-36 hours • Full ketosis and fat burning • The liver is making ketones • Decreased appetite • Decreased ghrelin • Increased BDNF (new brain cells) Stage 4: 36-48 hours • Autophagy • Kill cancer cells • Decreased oxidative stress • Decreased misfolded proteins • Increased memory Stage 5: 48-60 hours • Insulin sensitivity super boost • More autophagy • Less inflammation • Atrophy healing • Protein sparing Stage 6: 60-72 hours • Immune system regeneration • Spike in immune stem cells • A 2014 study demonstrated that a 72 hour fast led to a complete rejuvenation of the immune system, and people on chemotherapy had less damage DISCLAIMER: This video is purely educational and cannot be considered as personal medical advice.
