gout and fasting

I just found out that my boyfriend has gout. He's very young and usually quite healthy. He now at the age of 23 has gout in his elbow. I'm a strong believer in fasting and I think it could be beneficial for him. Gout is caused my too much uric acid in your body and possibly you kidneys not functioning to their fullest. I'm worried that fasting could possibly cause even more strain on his kidneys. Does anyone have any advice of recommendations on this subject. Thanks.
