Insulin is a hormone secreted from the beta cells of the pancreas, which helps to lower blood sugar. Glucose (sugar) binds to the insulin receptor and enters the cell and balances blood sugar. However, in people with insulin resistance, insulin receptors in the cell develop insensitivity to insulin and glucose is difficult to enter the cell. This causes more insulin release. Excessive insulin causes a feeling of hunger, a desire to eat something constantly, especially a desire for dessert. Inactivity, obesity, irregular nutrition, stress are among the most important factors that trigger this resistance. Insulin resistance is calculated by the HOMA-IR value by looking at fasting, fasting insulin and fasting glucose. If this value is above 2.5, it indicates that you have insulin resistance. The most important treatment is nutritional therapy. Because foods with low glycemic index increase blood sugar more slowly, they increase satiety and promote weight gain. Therefore, instead of carbohydrates with high starch and glycemic index ratios such as rice, potato, corn, carrot, white bread, sweet, whole grain carbohydrates with low glycemic index such as whole wheat bread, oats, wholegrain pasta, bulgur, vegetables should be added to the feed. The nutrition program should be person-specific, and the dietary checker should be designed according to the muscle fat measurement. Weight loss and body fat reduction is one of the most important points in the fall of insulin resistance. For this reason, fat and carbohydrate should be avoided predominantly from feeding. Long-term hunger, balances blood sugar and increases the demand for carbohydrates. To prevent this, 3 main, 2 or 3 snack meals should be made on a regular basis. One of the most important things to be done in order for insulin resistance to come to normal is to walk in moderate temp for 30-40 min every day.
