Ignored my doctor. Now better health and Low to no pain

Started the healthy Keto about 5 years ago after struggling with lower back pain for decades and being on pain drugs even including Morphine. During my school life, I was bullied for being fat. In my 20's, I used to exercise 2 hours a day 7 days a week, and never had great health or body. Now in my late 40's, I have the health and body I've always wanted and virtually no pain. Just doing 20 minutes of HIT per day, cold showers, and eating only at 2 pm and 6:30 pm. Now my blood works look so much better too. 1.82cm tall, 82 kg weight, CRP HS 0.45, ABA1C 32, Vo2Max 48.7, Average Ketones 0.9, Av Resting HR 49
