I am at 23 hours into fasting. I am going to go at least 48 hours...hopefully to 36 hours. Sounds stupid right? Here is what happens to our bodies while fasting.
1. The fed state occurs within the first few hours after eating. During this state, your blood sugar and insulin levels increase, while levels of other hormones, including leptin and ghrelin, shift.
2. A few hours after eating, your body transitions into the early fasting state, which occurs when glycogen, amino acids, and fatty acids are converted into energy.
3. The fasting state lasts from about 18 hours to 2 days of fasting. At some point during this state, your body enters ketosis, a metabolic state in which fats are broken down and used as an energy source.
4. The long-term fasting state, or starvation state, occurs around 48 hours into fasting. During this period, insulin levels decrease, ketone levels increase, and protein breakdown is reduced to conserve muscle tissue.
Here are the benefits
1. When you fast, insulin levels drop and human growth hormone (HGH) increases. Your cells also initiate important cellular repair processes and change which genes they express.
2. Intermittent fasting helps you eat fewer calories while boosting metabolism slightly. It’s a very effective tool to lose weight and visceral fat.
3. Intermittent fasting can reduce insulin resistance and lower blood sugar levels, at least in men.
4. Studies show that intermittent fasting can reduce oxidative damage and inflammation in the body. This should have benefits against aging and development of numerous diseases.
5. Studies show that intermittent fasting can improve numerous risk factors for heart disease, such as blood pressure, cholesterol levels, triglycerides, and inflammatory markers.
6. Fasting triggers a metabolic pathway called autophagy, which removes waste material from cells.
7. Intermittent fasting has been shown to help prevent cancer in animal studies and some human studies. Research in humans showed that it can help reduce side effects caused by chemotherapy.
8. Intermittent fasting may have important benefits for brain health. It may increase growth of new neurons and protect the brain from damage.
9. Studies in animals suggest that intermittent fasting may be protective against neurodegenerative diseases such as Alzheimer’s disease.
10. Intermittent fasting may help you live longer, according to studies in animals.
