I had absolutely no idea that food could impact the pain in my body until I read Ultra Metabolism and started following it- most of the things are acceptable on SBD as well and now I do a combo. I was aboslutely amazed at the fact my back stopped hurting as did my limbs. I am sure it was from the inflammation. My parents also have been doing it and my DF has psoriasis and its calmed that down as well. I think its a great book and would recommend it. I don't know where my mom found them but they were cheap, of course the library is a good option too!
Also, I just got back from vaca and ate crappy- this morning when I woke up I couldn't think anything other than how rediculous I am bc i felt miserable when I woke up. no energy, my back was killing me, and I just felt like a beached whale. so, fasting today and back OP tomorrow~
The book explains a lot on food alleries- and the way your body handles different foods and how it communicates with itself depending on what we are eating and doing!
