Low-carb healthy fat living. Intermittent fasting. What’s your why?: https://connect.mayoclinic.org/discussion/low-carb-healthy-fat-living-intermittent-fasting-whats-your-why/

Although I had intense pain with the PMR and had trouble performing the simplest of tasks, I was able to continue my daily walks on a limited basis even before starting on the prednisone. I found that PMR pain typically lessens as the day goes on, especially if you make an effort to move and be active. I learned that movement, painful as it is with PMR, is a better remedy than almost anything besides prednisone. It helps to get out, see people, and do things you enjoy to distract yourself from the pain. The proper dose of prednisone allows you to resume most activities with minimal side effects from the medication. The highest dose my rheumatologist would allow me to take was 15 mgs, which did not completely relieve all the pain, but it was enough to allow me to function again. I am now down to 7.5 mgs. and due to reduce to 5 mgs. in a couple of days. I have gotten progressively better even though I am consistently reducing the dosage of prednisone. I have not noticed any unwanted effects from the medication. I have also tried to eat foods, such as vegetables, fruits and especially berries that are purported to reduce inflammation and have been taking fish oil capsules and turmeric. I am 75 years old and I weigh approximately 100 pounds. The prednisone has not caused any weight gain or loss. I am now six months into this flare-up and have improved significantly in the last two months. I am hoping to be able to discontinue the prednisone by September. My rheumatologist advised that it would take three months to get completely off of it, so that is what I am shooting for. I hope this is helpful to you and that you are soon feeling better.
