Carl Franklin and Richard Morris ask the 2KD community to relate their NSVs (Non-Scale Victories) or all of the benefits of a ketogenic diet they've noticed other than weight loss. The results may surprise you. The dudes also announced Ketofest 2017, an idea to hold a ketogenic lifestyle festival in July of next year. If you're interested, go to ketofest.com and get on the mailing list.
Carl mentioned that a ketongenic diet is specifically good for Rheumatoid arthritis(RA), in fact of the two markers tested
it only lowered one, but fasting was shown to lower both. So it may well be that fasting, which we know is easer if you are adapted to a ketogenic diet, is your best strategy to deal with RA.
