KG.... I'm type 2, carbs are the killer. All that good stuff, rice, pasta, potatoes, bread, cakes, cookies....you get the idea.
Every diabetic reacts differently to carbs and sugars. I can eat bread in moderation, but rice and pasta drives my bs through the roof. Fresh fruit does also, except apples.
I cut out all the candy, desserts etc, it was hard at first, but does not bother me now. I can have just a bite of pie, cake, ice cream etc and that's enough for me.
Read the labels, sugar is in everything. Jams, jellies for instance. one brand might have 15g sugar and another of the same flavor will have 7g.....you get the idea.
Lets say you go out for Mexican, he gets the big burrito w/ rice and beans.
That tortilla could have 40-50 carbs alone, then the rice and beans, and all those fresh hot tortilla chips that are set in front of you with salsa. You could hit 100 carbs in no time.
I found a pasta replacement, called tofu shirataki not nearly as good as real pasta, but you can have that plate of pasta and not worry about the carbs.
I try to eat about 50% salad/veggies, 30 protein, 20 carbs
