I just found this one out the ‘easy way’ lol. I had some bananas sitting on the bench. They were starting to go black so I brought out my blender, threw in all of them (5), some low fat milk and a tablespoon of malt energy drink powder (we call it Milo here). I forgot I had no ice cream left over but the bananas just had to be used anyway and I couldn’t think of a better way than milkshake! You don’t necessarily need ice cream (you can have a low fat and lower sugar milkshake this way anyway) as the bananas help to make it thicker than straight milk. I have been keeping to my low fat diet. The 5 bananas and about 4 cups of milk came to about 5 decent-sized glasses of milkshake. I had about 1 and a half and I was FULL!
I’d put that on par with a meal replacement. Best to have in the morning and there are no added fats, sugars or preservatives because you’re making it yourself.
