When I started keto last November it was miraculous it dropped my A1c from 106 down to 59 within 11 weeks, but I noticed that my knees started getting unbearable pain due to osteoarthritis and I had to have steroid injection in my right knee , it never took the pain away completely , but it did ease it . Around June I started getting the same unbearable pain in my elbows and suspected back then that the high fat could be the cause . Around six weeks ago i was really ill with vomiting and was always feels nauseous (I made a thread about this ,stopping keto) , I decided that keto was the cause of my nausea and stopped it straight away . The improvement was almost instant and I introduced carbs and keep between 80~130 a day , I've lost a stone in weight I feel amazingly well and the pain in my elbows and knees has all but gone . Now I am not sure if it is the high fat that was causing my pain in the knees and elbows , but it seems to have cured me since stopping keto . Keto is amazing and I am so grateful that I did this diet because it dropped my A1c miraculously , but it made me very ill over the months. I get my A1c result Tuesday so I will post on here what they are . Fingers crossed it has improved . Thanks for reading , I'm interested to know if anyone else developed pain while doing keto , and also I must add that I had pain in my thumb and wrist too which has now almost gone . Wondering if there's a connection .
