I was recently diagnosed with type 2 diabetes and was floundering trying to find what I should/should not eat. I even went to a dietician, who was telling me I could eat Cheerios - which would've given me a blood glucose shock. I bought about 6 books. This is by far the best book out there. It gives you a very easy way to measure the size of your daily portions of proteins, fruits & veggies, and snacks - yes you can have snacks. This book changed my life for the better. At first I was overwhelmed with trying to test my blood glucose levels, taking meds, dieting, exercising, and figuring out what I have to stop eating. My glucose levels were very high - and I was scared to death. After 5 weeks I've lost 20 pounds and this book has given me the confidence to know that I am eating things that won't spike my glucose levels. I'm feeling better then I have in a long time. Largely due to getting this book. And it doesn't cost you a lot of money either. The funny part of this is - now that my friends have seen how good I'm looking - they all want to go on this diet too - and none of them are diabetic.
