Metformin, sold under the trade name Glucophage, is used to treat diabetes, but several studies show that it also helps non-diabetics to lose weight by reducing hunger (1). You may be overweight because your body makes too much insulin, especially if your store your fat primarily in your belly. When you eat, your blood sugar level rises. The higher it rises, the more insulin your pancreas releases. Insulin makes you fat by acting on your brain to make you hungry, your liver to manufacture fat, and the fat cells in your belly to fill with fat. So the treatment for this type of obesity is to avoid foods that cause the highest rise in blood sugar and to take medications that prevent your blood sugar levels from rising too high. Avoid bakery products, pastas and all foods made from flour, fruit juices and everything with added sugar. Eat fruits and root vegetables such as potatoes only with meals. Glucophage is a safe medication that prevents blood sugar levels from rising too high, but you defeat its effects by taking foods that cause rapid rises in blood sugar levels. bbyeeeeeeeee.
