Unless theres something I missed if this is what works for you and the only way you can stick to the diet and you lose weight I don't see a problem. It is definitely better than the typical american diet. Of course getting to a keto diet with more variety would be best but I am doing something similiar to what you are doing except I just eat beef or pork and spinach with butter and sugar free bbq sauce. Its very limited as far as selection but its simple and it works for me. Nothing wrong with simple.
