I (painfully) found out I was pre-disposed to gout only after going on a high protein diet. That said, if you're careful to avoid too many high purine meats, you can avoid that side effect.

There is a large number of ways that one can turn an exclusionary diet into an unhealthy diet - by what you choose to include. This doesn't make the exclusion unhealthy, or the excluded food necessary. Most ULC dieters I know are LCHF, while restricting their protein intake carefully. ULC is not high protein.
