Ahh. check out THIS LINK. Its one of the members of this site. There is a wealth of supplemental information. I used the nutrition calculator here, which helped me get a handle on what ratios I was supposed to be eating.
Ask a lot of questions in this forum and read old pages of this forum. I was lucky enough to have a few of the members here (and one in particular) help me to understand what was going on and make good recommendations.
Find foods that you can eat and cannot. Realize that you can replace a lot of foods. Another member here put it wonderfully, there are two types of low carbers, those that make due without and those that replace whats gone. I like to think I do both. But know this, you will go a lot further on this eating plan making your own meals and items. Heck I just made low carb stuff, cranberry sauce, cauliflower mashed, and pumpkin pie for TG. The dishes were a hit!
Cauliflower is a Godsent. It can replace rice, potatoes, and tons of other starches easily.
Low carb is high fat, not high protein. Try to bear this in mind. Also, Im coming to terms with the fact that low carb / high fat doesnt mean I can eay just any old fat and protein. It still needs to be healthy like fish, minimal packaged "low carb"
mixes, etc.
Take your time getting into it. I lowered my carbs over 2 months and am really happy with the 35 a day I eat now. Plus I couldnt be happier with my BGs. Best theyve been in the 25 years Ive had D. Heres my days BGs from yesterday / this morning. The range is 70-120 mg/dl
and lastly, when you realize your Dr. has been telling you BS. dont let your anger get the better of you. Take it in stride.
Hope it goes well for you!
