I figured there would be interest in this article. This discusses the effects ketogenic diets have on pain - and also inflammation! Many people have been asking about this. Interesting stuff, for sure. While it's primarily neurological, the implications may perhaps be applied globally?
"Ketogenic diets are well-established as a successful anticonvulsant therapy. Based on overlap between mechanisms postulated to underlie pain and inflammation, and mechanisms postulated to underlie therapeutic effects of ketogenic diets, recent studies have explored the ability for ketogenic diets to reduce pain. Here we review clinical and basic research thus far exploring the impact of a ketogenic diet on thermal pain, inflammation, and neuropathic pain."
