i am type 2 pre-diabetic. i found this article the other day, and it is pretty helpful for type 1s as well.http://www.insulinfactor.com/graphic...ng_article.pdf

also, make sure you don't eat or drink anything, ANYTHING with high fructose corn syrup. it is the worst type of sweetener for diabetics. check the gatorade for that, i have found that their "lighter" version contains hfcs as well.

that being said. you need to carb up before you ride, play around with the amounts. drink water or low car drink during. if you still feel wonky after, then fruit. natures' candy or some slow releasing carbs such as whole grains are going to be your best bet. after i ride i do a fruit and yogurt or milk smoothie. milk and chocolate milk are great for post ride. just make sure it is low fat. also, if you feel like you are having a dip, and you need some sugar, make sure whatever you eat doesn't have a high fat content, it slows the release of the sugars into your body. so, no chocolate or things with nuts or nut butters in them if you need something quick. hope that helps, if you have any more questions, feel free to pm me! good luck!
