I am in the same shoes. Exactly like you. I am now 2 weeks on low carb diet. And it is so hard to find balance between cholesterol and low carb diet. I have decided to ignore the Cholesterol within limits. I am not sure if that is OK, but I avoid obvious fat on foods, and try to cook food so if there is any fat it should be out, but also use less fat when cooking. Not too sure what else I can do.
I eat fish, chicken, cooked red meats without fats but not too often.
rosted chicken can be good for lunch without any bread with non starchy vegetables as a filler, and I have lots of cucumber and feta as snacks and some meat or egg..
I also try to eat lots of small meals during the day. But I have just started so not too sure what to do.
And I test before and after new meals plus every morning to see how foods affect me. I am still prediabetic but knowing that D is a progressive disease, I try to stay within the limits of a normal people in order to slow the progression and avoid future complications.
Another most important thing for me is exercise. I found by measuring that 5 min of exercise after food drops my BG (measured before and after exercise) frops it by 20 popints, so Now I exercise after every meal for 5 min on a machine.
