Insulin is a hormone inside the body that is produced by the pancreas. It controls the level of glucose in the blood and is responsible for signaling to the body whether to burn or store fat.
According to Robert H. Lustig, MD, who’s a professor of Clinical Pediatrics at the University of California, San Francisco, newest research shows that some people may be overweight because of a chronic disorder of insulin overproduction in their bodies.
Lustig explains that chronic insulin hyper-secretion and/or insulin liver resistance are the main culprits of weight gain for most of people, and in order to lose weight and keep it off one must control the level of insulin in his or her blood.
Chronic insulin hyper-secretion occurs when pancreas produces more insulin than what is required by the body. Insulin liver resistance occurs when the liver requires more insulin than what is normal and it usually leads to a similar overproduction of insulin by the pancreas.
In both cases, too much insulin in the blood stream will make the body incapable of detecting the presence of leptin, which is the hormone responsible for letting the body know when it’s time to stop gaining weight.
How to Prevent or Treat Insulin Overproduction
To prevent or treat the chronic insulin overproduction in the body, three lifestyle changes must be made:
1. Maintain a Very Low Carb Diet. By limiting the intake of carbohydrates, such as rice, bread, pasta or candies, you can stabilize the insulin production in the body. Carbohydrates trigger the production of insulin the most and must be therefore avoided. Instead of eating carbs, try to eat more foods that contain protein and healthy fat. Some examples of foods rich in protein and healthy fat are poultry, fish, shellfish, eggs, tree nuts, and seeds.
2. Limit the Consumption of Fructose (Sugar). You must limit the consumption of foods that contain sugar. This includes sweets, sugary drinks such as sodas and juices, and any foods or drinks that contain High Fructose Corn Syrup.
3. Get Regular Exercise. Physical inactivity can lead to the development of chronic insulin overproduction as well. To avoid this, try to get at least three hours of exercise per week, but the more the better. Exercise seems to play a very important part in healthy functioning of the entire body, including the production of insulin.
Why This Information Is Important
If the chronic insulin overproduction theory is correct, then it explains very well the current obesity epidemic in the Western world.
In particular, it shows why over-consumption of simple carbs and sugars leads to weight gain and obesity and why the weight gain regulatory mechanisms in the body (such as leptin) are not functioning properly.
Whether true or not, over-consumption of simple carbs and sugars has been shown to lead to weight gain in many other studies so you must incorporate this information into your own eating pattern if you want to lose or prevent gaining excess weight in the future.
