I agree too, thats alot of banana's!!! One small banana a day counts as 1 exchange, a big banana counts as 2 exchanges.
Also by looking at ur normal intake ur not eating much.. Like becky says you need some more calories, maybe bigger size portion of meals and swapping a banana for an Apple or a bunch of Grapes oh and also taking ur formula through out the day.
I am trying to stick to my diet but am only on 6 exchanges and ur on like 45 exchanges…Maybe thats too much for you?? but if u want to buddy up private mail me and i'll try helping out as much as possible.
