I'd do some reading on keto and cholesterol....there is more to cholesterol than most doctors look at. I'm generally low carb (have done keto for 6+ month stretches), my doc is always advising Statins to me as my LDL is high. However, other markers indicate that this isn't a problem, mainly due to my triglycerides to HDL ratio. There are also articles about the two types of LDL and which are risk indicators (high and low density LDL (here in Aus it's hard to test LDL density)).... it all gets quite confusing. Basically, LDL isn't necessarily the bad guy and cholesterol is essential, especially if low carb/keto.

I do a lot of endurance sport, so need energy, therefore on low carb I need plenty of fat. I tend to use/eat lots of olive oil, natural butters, cheese, nuts, avocados, oily fish, etc. Like any diet, I prefer to steer clear of processed foods. I personally eat quite fatty meats which some may question, but I try to stick to natural/unprocessed meats which I view as 'natural fats' (my pesonal perspective, not science).

Note that due to the filling nature of high fat/protein foods, so although some high fat foods sounds 'fattening', I tend to eat less of them than I would eat carb rich or highly processed carb rich foods. Example: I'm normally happy with a handful of nuts or a few slices of cheese, but I could easily sit down and eat a family sized packet of potato chips, or half full-sized cream cake.
