Read a bit more about it and consult your medical advisor. From what I understand of the ketogenic diet, your overall readings for LDL and HDL might not chance, but it is the full breakdown that is important. It's the types of fats that float around in your bloodstream that change. It's not an area of expertise for me, as I have never had a problem with cholesterol. I do know from my experience, though, that the ketogenic diet requires 110% commitment. When I was trying to follow it to the letter, I still never once recorded a "good" level of ketosis (I was taking blood tests). It was probably the artificial sweeteners in the chocolate and sweets I would eat to keep myself sane, upsetting the ketosis, because the other food I was eating was 100% counted, to fit the precise macros allocated to myself and my husband. Yet we couldn't achieve proper ketosis and our weight loss was sporadic. If you are achieving ketosis though, you should have had at least 3-4 weeks of almost alarmingly good weight losses. From what I've read, I'm not alone in discovering that a small amount of the wrong food, even once a week, is enough to throw this diet completely off kilter. I had to stop eating out completely, which is why I'm not trying to follow it now. It takes a LOT of planning and effort and organisation to have the right food there at meal times.
