Are there any fruits or veggies that will make me gain fat/weight?

i want to eat mangos and melons and pineapple and stuff but because its so good i honestly just cant eat just a little ill eat maybe 9 or so mangoes or 3-4 watermelon and a few pineapple so im wondering will that make me fat because it has a high glycemic index? please answer the question and dont tell me to cut back on the fruit please and add other stuff. and i do eat a really healthy diet though. just tell me if what i said will make me gain weight and list other fruits and veggies that might if there are any. thank you sooo much :)
