Hi T!

I'm also a diabetic and have absolutely no problems with being in ketosis as long as my blood sugars are well controlled. I've been following a low carb WOL for 2+ years now without a problem. Another book that you might want to get since you're a diabetic is Dr. Bernstein's Diabetes Solution by Richard Bernstein, MD. He's a type 1 diabetic who has been low carbing for 40+ years at no more than 30 grams of carb per day and has actually seen his diabetic complications reverse themselves. It's a good book for diabetic low carbers to read even if they don't choose to follow the plan.
HTH!
