Insulin is such an important hormone regulating our metabolism. Inside the pancreas, insulin is made in the beta cells, which are part of the Islets of Langerhans. With each meal, beta cells release insulin to help the body use or store the blood sugar it gets from food.
The more carbohydrate you eat, the more insulin your body releases to regulate your blood sugar and keep it within a healthy range. Excess insulin production tells your body to store the excess of energy as body fat.
Large amounts of body fat and frequent high insulin levels decrease your cells’ sensitivity to your own insulin. This results in insulin resistance, and it is linked to many health conditions. When glucose continues to build up in the blood instead of going into cells, it can lead to serious problems like organ damage, nerve damage (neuropathy), blindness, hearing loss, heart disease, and stroke.
High insulin levels suppress the production of two other important hormones: glucagon and growth hormone. Your body secretes glucagon when your blood sugar levels are low because its job is to trigger the release of fat to be burned for energy. High insulin levels shut down glucagon production, so you can’t burn fat. Your body uses growth hormone for muscle repair and building new muscle tissue. Hence, insulin resistance reduces muscle development, which keeps your metabolism slow.
Low-carb diet is a perfect option if you wish to reduce your blood sugar level, to keep insulin production low and help reversing the insulin resistance. Focus on having substantial amount of quality protein and green leavy vegetables with minimal level of refined carbohydrate in your daily meal. Proteins and fibre can help you manage sugar craving and feel full for longer.
