Maltodextrin, do weight gainers = fat gainers?
Ok so I was looking at cytogainer I believe it's called and its main source of calories comes from carbs, more specifically, maltodextrin. It claims that maltodextrin is a complex carb and that it won't cause an insulin spike and won't make me fat, but I'm skeptical. I googled it and apperantly maltodextrin is technically a complex carb because of it's chemical structure, however, a couple of things I read actually said it acted like a simple carb anyway.
Basically it's a pain in the ass to eat so much food and a gainer would help me out a lot for the sake of convenience, but if it's just sugary protein powder then I don't want any part of it. So, is cytogainer (or any other weight gainer for that matter) going to make me fat or is maltodextrin a good source of carbs? Also, if maltodextrin is just sugary crap, would it still be ok to take a gainer shake like 30 minutes pre-workout?
