So the headline is fairly self-explanatory, but basically I have been dissolving about 250g (1,000 calories worth) of maltodextrin in 64oz of water and drinking it throughout the day, in an effort to increase the amount of carbohydrates I take in as well as total calories.
The reason for this is that I'm in a bulking cycle for weightlifting, and I read in a nutrition textbook  about the importance of having a very large intake of carbs, about 60% of total daily caloric intake. I was wondering if there are any possible negative effects of doing this long-term: I've been doing this for about two months now, and plan to continue for another two. For instance, could this put me at an increased risk of diabetes? I am careful to still get a lot of nutrients in my diet, both through eating plenty of fruits and vegetables, as well as taking a daily multi.
Thanks in advance for your input!
