I eat several pieces of fruit per day, Ive noticed this board is tremendously biased when it comes to fruit, dont buy into it.
you can "burn" off alot more than one puny piece of fruit per day, and its not like all the fructose is hitting your system at once, thats the great part about fruit. It doesnt bloat me at all and in addition the the broccoli and nuts I eat keeps me quite regular, I dont really even use toilet paper anymore, clean sweep 90% of the time.
The fruits I listed are low-moderate GI compared to melons and bananas etc so I think those are the best choices. although its all low calorie its best to get the most fiberous ones. Apples and Pears are my favs diet and taste wise. Kiwi is easy to peel, cut the ends off and run a spoon around the skin to get it out in one piece.
Look for variations and cross strain fruits to mix it up. I Like Fuji's , Gala's, Pink Lady's, all kinds of apples and the Bosc and asian Pears are killer. you can find Tangelos to , which is a citrus cross strain youd prolly like.
