IMO, I think that is more of a saturated fat issue, and only a subset of the population is like that. Others solve their health issues through eating a lot of red meat.
A leaner cut like tenderloin is fine.
Ultimately you just want to keep the calories you get from saturated fats from animal sources to less than 10% of your daily calories. You can still enjoy a nice steak or burger every once in a while, but they shouldn't be a daily staple if health is a priority.
Try eating the usual health-promoting diet high in fiber and low in saturated fats from animal sources, mostly whole foods, lots of fruits and veggies and legumes and whole grains, lean meats, etc.
After a few months, check your blood work.
Then reintroduce fattier cuts of meat into your diet and see what your numbers do after a few months.
