HI I followed the SCD diet years ago and it helped me so much I didn't know i was celiac back then I just knew I had bad digestion issues. I followed it about 95% adherance for 2 years as I didn't make my own condiments and ate out carefully which is not recommended, but I had great results. It is not a low card diet, you are allowed unlimited honey and things like dates and raisins, you add fruit in as you heal you can also have beans as you heal. I am gearing up to starting it again now that I found out I am celiac. There is also the GAPS diet which is SCD on steroids. I still make the SCD yogurt and every time I try adding in different probiotics I get into trouble SCD worked for me I just hate to give up my popcorn : (
If you are interested in exploring the carb issue...I would really encourage you to look into the work of Chris Kessler, Mark Sisson and other advocates of the Paleo diet and lifestyle. I went paleo to manage my Celiacs and IBS. I've looked into doing SCD and GAPS and now FODMAPS...might want to look into that instead...my may not need to go full SCD as it could be a FODMAP issue. I geek out on nutrition stuff. Dave Osprey has the bulletproof executive podcast that interviews all the latest researchers on nutrition and fitness. Hope you find some useful information. I can provide you with plenty of books and websites to learn more about SCD and/or FODMAP. good luck.
