I've been a diabetic for 15 years & I feel amazing by day two with just following the protocol <which is super easy>. Its the clearest laid out plan I've read & even if you dont reverse you're diabetes, the nutrients alone emensly help give you energy & take down inflammation, which in return you start feeling really good. I'm excited to finish the protocol & then keep the receipes for everyday cooking. Yum! Really worth the investment.
