Glycemic Index (GI)

The glycemic index is a ranking of carbohydrates on a scale of 0-100, depending on the way they affect blood sugar levels when they are eaten. High GI are carbohydrates that are digested very fast, and are quickly absorbed into the bloodstream, causing a marked rise in the blood sugar levels.

The digestion of low GI foods is slower, and when absorbed they don’t cause a rapid rise in the sugar levels.

Low GI foods have more health benefits for the body and are highly recommended. They promote the mobilization and use of fats for energy instead of carbohydrates. The main reason for the increased rates of obesity and diabetes is that a typical western diet is composed of mainly high GI foods. The scale groups foods as follows: low GI >55 and high GI< 55.

Where Does the Banana Rank?

The GI of bananas ranks between 42-62 depending on how ripe your fruit is. This means that bananas are ranked low on the GI scale relative to other carbohydrates, and when compared to other fruits, it ranks higher. Overall, banana is classified as a low GI food.

Health Benefits

Bananas contains fiber and resistant starch that helps prevent fat build up. Compared to other fruits, bananas contain a lot of starch, but the most interesting part is that it doesn’t cause weight gain. The resistant starch contained in bananas acts as soluble fiber in the body.

The starch is not digested in the small intestine and is only acted on by the good bacteria in the large intestine.  The starch and fiber found in bananas prevents fluctuations of the blood sugar levels that can cause weight gain.

Maintaining balanced sugar levels is key to preventing unwanted weight gain. This is because when your blood sugar levels are high more fat will be stored, and when the levels drop below normal your appetite rises.


Bananas have a moderate calorie content and can be safely included in any diet without causing weight gain. Therefore, consuming bananas cannot be said to be the root cause of weight gain and belly fat. You can now comfortably enjoy your bananas either cooked or raw, and eliminate any fear of adding belly fat. So, it’s safe to say that bananas don’t cause belly fat.
