Explain to me what a better diet would be?

Personally I would be eating more carbs and fats to avoid performance and muscle loss, and I would be training completely different. You can keep making progress, but you are going to have 0 muscle. Having a higher LBM makes you have a higher RMR. I would slowly increase calories and add in other food types and try to build some muscle without gaining lots of weight, your body sounds like it needs a break, just don't overdo it so you negate some of the work you have already done. But that's my opinion on the matter, you can lose the rest of the fat later, just need to make sure you are consistent and constantly improving in one area or another, ie muscle building or fat loss, or maintenance.
