I had my first gout attack a couple years ago several weeks into a keto diet (had done keto before with no issues). I found https://www.virtahealth.com/blog/keto-adapted https://www.virtahealth.com/blog/keto-adapted which shows a graph of uric acid spiking as you begin the diet and returning back to baseline after several weeks, which was something I didn't know before, but I was still confused because it was already at several weeks. To make a long story short I discovered the next year that the culprit was pistachios. So long as I don't eat too many of them while dieting, my foot is fine.
