Too much fruit bad for weight loss?

Well im just trying to burn about 8 more pounds im 158 trying to be 150. If i eat a bag of grapes a day along with other fruits such as some strawberries bannas etc. Im legit obsessed with fruits and veggies. Will it be harder to lose weight if i eat too much of them a day? My other half of the diet such as foods are chicken tuna fish lentils whole grain spaghetti and whole grain cereal throughout the week .
