As someone who had gout before fasting and low carb, my first fast definitely triggered a gout attack. But after that fast, fasting and low carb has drastically reduced the number of gout attacks I have had.
Also, fasting is also the fastest way for me to resolve a gout attack. Eating during a gout attack increases the pain level, and prolongs the attack
Bringing that uric acid out. Got to go through it to get rid of it. Bicarbonate and water fast for a few days after it presents on your dry fast would be a sensible approach. Say 72 dry then 72 bicarbonate and moderate water (say a litre or two)
Emotional and physical diseases, aches and pains are sequentially healed to a degree or healed to completion if the fast is done for a long enough duration. We are forced to feel and sometimes forced to feel to an amplified degree the pain of the emotional or physical wound/disease while we heal, process and finally let go of it. Sometimes breaking the fast and interrupting that healing process can worsen the emotional/physical wound or disease and make the pain more intense than what it was before you started the fast
