So today I was training a client and we were talking about which fruits were good or bad for fat loss in terms of how much sugar they have. I said that bananas are OK because they’re low on the Glycemix Index (GI). The glycemic index is a rating given to foods based on how much they spike your blood sugar levels. The higher the food on the GI scale, the more it will spike your blood sugar.

With regard to fat loss, you don’t want to eat foods that are high on the GI scale because a spike in blood sugar means that you body has to release more insulin to process that sugar. That’s not good because higher insulin levels have been shown promote the storage of fat in your body. Therefore, you want to eat foods that have a low GI.

Back to my story: So another trainer heard me saying that bananas are ok because they are low on the GI scale and she said that wasn’t true. She said that bananas are actually very high on the GI scale.

So I did a little research and this is what I found:

Bananas have a LOW glycemic index rating. They are ok to eat. However, the riper a banana gets, the more sugar it will have so my other fellow trainer was also correct to an extent. I’m not saying you have to eat green bananas, but if they are too ripe, then they will definitely have more sugar.

Bananas are also a slow digesting carbohydrate and a good source of fibre.
The verdict: You can eat bananas.
