Total cholesterol level doesn't really give much guidance - other than this should be below 4.0 for high cardiac risk patients(ie. diabetics). You should check if your doctor has your breakdown to HDL-C, LDL-C and triglycerides. HDL-C is the good cholesterol and typically you want levels as high as possible. LDL-C and triglycerides ideally as low as possible.
Unfortunately it is still a common myth that dietary cholesterol is the major cause of high blood lipids. In fact carbohydrates are a bigger factor especially for raised triglycerides and implicated in low HDL-C levels. But some find that LDL-C can stay high or rises slightly on LCHF.
At diagnosis as Type 1 my total Cholesterol was 7.74, HDL-C 1.58 (should be > 1.00), LDL-C 5.44 (should be < 2.60) and Triglycerides 1.53 (should be < 2.30).
After a few years mostly low carbing my LDL-C is often still over optimum level, say 3.0, while HDL-C is always above 2.50 and triglycerides under 0.70. Key ratio of Total C /HDL-C under 2.25 (should be < 4.50). Unfortunately not total consensus among doctors which numbers matter most - some still monitor LDL-C as most important (hence those statins prescriptions...), other prefer to track Total cholesterol to HDL-C ratio.
