How does insulin make you put on weight?

You may find yourself overweight because your body makes too much insulin. Having additional fat around the waist or belly is a tell-tale sign that your body is producing too much insulin. When you eat your blood sugar level rises. The higher it goes the more insulin your body needs to cover the additional levels of glucose in the body.

In a nutshell, insulin can make people put on weight as it acts as a trigger to the brain that more food is required by the body. In effect it can make you more hungry more of the time. The theory goes that the higher your insulin levels, the more your brain gets used to eating large amounts of food. Insulin also makes the liver produce fat  in the gut.

How can metformin help you lose weight?

After eating a meal the sugar in the food is released into your bloodstream and is absorbed by your liver. Your liver will then release that sugar back into the bloodstream which causes your blood sugar levels to rise. As a result your pancreas secrets insulin to cover this release of sugar. Metformin or Glucophage in affect reduces or restricts this release of sugar from your liver. This means that your body does not need to produce as much insulin. As discussed above insulin can make you hungry and can make you fat. If the body does not produce as much insulin the result can be weight loss for diabetics.

You still need to watch what you eat

Glucophage is a safe medication that prevents blood sugar levels from rising too high, but its effects will be severely limited if you eat foods that are very high in sugar eg coca cola, sweets, high GI foods like chips etc. This is because those foods cause your blood sugar levels to rise too rapidly. All told, your diet is still key in managing your diabetes even if you are taking metformin/ Glucphage.
