I don't think so.

A few years ago the only food alkaline charts available on the Internet all showed that lemons and then watermelon were the most alkaline foods. I see there are far more 'experts' now. There are some now that claim avocado is, stevia is, or potatoes are. But lemons are still either the top or near the top on all. Even though they would be classified as acidic as in citric acid they effect the body in an alkaline manner. This I know. I experimented with it for years. But as far as ketosis is concerned I claim complete ignorance. Lemons and watermelons balanced my ph in a big way. This I truly know. Here are some current charts.

I do appreciate your input though. I will do more research.
