Dr. Jason Fung – ‘A New Paradigm of Insulin Resistance’

Intermittent fasting is a cyclic diet plan of fasting and eating. The goal is to systematically hungry the body in order to trigger the time to burn fat. Although research is still ongoing, this method may not be suitable for everyone. Evidence shows that correct indirect fasting can help lose weight and lower blood pressure and cholesterol , Prevent or control diabetes, improve brain health. During meals, carbohydrates in food are broken down into glucose. Glucose is absorbed into the blood through the intestinal wall and is transported to Various organs serve as energy sources. Excess glucose will be stored in the liver and adipose tissue in the form Glycogen and fat. Between meals, when the body is fasting, the liver converts glycogen Return to glucose to continuously replenish the body with energy. Generally, it takes about 10 to 12 hours for people who exercise less to run out of glycogen stores. However, people who exercise may spend less time consuming glycogen. Once glycogen stores are exhausted, the body starts to use fatty tissue As an energy source. At this time fat is broken down into free fatty acids and then converted Fuel for extra metabolism in the liver. Therefore, if the fasting state lasts long enough, the body burns fat for energy, And lose excess fat. Subtracting excess fat will translate into a series of related health benefits. Insulin is a hormone that drives glucose into cells. Insulin levels will be adjusted by the body to match the glucose in the blood, and insulin will rise after meals Insulin will decrease between meals. Because insulin is secreted after every meal, if you eat all day, Will keep insulin at a high level. Sustained high insulin levels may make human tissues insensitive, leading to insulin insensitivity -This is the characteristic of prediabetes and type 2 diabetes. Fasting helps keep insulin levels low and reduces the risk of diabetes. Fasting is also good for the brain. Fasting more challenges the brain or cognitive activity in the same way. Fasting promotes the production of neurotrophic factors and supports the growth and survival of neurons. However, fasting is not for everyone. People who should not fast include: -Children and adolescents-Pregnant or breastfeeding women -People with eating disorders, type 1 diabetes, advanced diabetes or some other Health problems-people who are underweight or weak. If fasting is too long or the operation is incorrect, fasting may also be unsafe. There are several methods of intermittent fasting, but the easiest is probably Only the extended night fast. Fasting for 16 hours a day and then eating within 8 hours is usually sustainable. To make fasting safe and effective, it must be combined with a balanced diet And provide good nutrition. It is important to drink plenty of water and know the physical limits of fasting. Fasting must be broken slowly. Binge eating after fasting, especially unhealthy binge eating, must be avoided.
