Fasting can help regulate blood sugar levels and improve insulin sensitivity from "summary" of The Complete Guide to Fasting by Jimmy Moore,Jason Fung
One of the key benefits of fasting is its ability to regulate blood sugar levels and improve insulin sensitivity. When we eat, our bodies break down carbohydrates into glucose, which is then used for energy or stored as glycogen in the liver and muscles. Insulin, a hormone produced by the pancreas, helps regulate the amount of glucose in the bloodstream by signaling cells to take up glucose for energy. However, in today's society where food is plentiful and easily accessible, many people consume high amounts of carbohydrates and sugar, leading to chronically elevated blood sugar levels. This constant influx of glucose into the bloodstream can eventually lead to insulin resistance, a condition in which cells become less responsive to insulin's signals, resulting in higher blood sugar levels. Fasting can help break this cycle by reducing the amount of glucose entering the bloodstream, allowing the body to use up stored glycogen for energy. As glycogen stores are depleted, the body begins to burn fat for fuel, a process known as ketosis. During ketosis, the liver produces ketones, which can be used by the brain and other tissues as an alternative fuel source. By lowering blood sugar levels and promoting ketosis, fasting can improve insulin sensitivity, making cells more responsive to insulin's signals. This can help lower overall blood sugar levels and reduce the risk of developing insulin resistance and type 2 diabetes. Additionally, fasting can also help lower insulin levels, which can further improve insulin sensitivity and promote fat loss.- Incorporating fasting into your routine can have a profound impact on your blood sugar levels and insulin sensitivity, leading to better metabolic health and overall well-being. Through the strategic use of fasting, you can help regulate your blood sugar levels, improve insulin sensitivity, and optimize your health.
