My ketogenic diet has not affected my cholesterol level

When people hear about high fat diets they assume that cholesterol levels and other indicators of heart disease risk will go up.
So after changing from low fat diet to a high fat, low carbohydrate diet (ketogenic) I wanted to find out whether or not there was an increase in HDL/LDL and cholesterol. I just received my lab results today which were the following:

Cholesterol: 176 and the optimal range is 140-200
Triglycerides: 26 and the optimal range is 35-150 (really low)
HDL: 91 and the optimal range is >40 (referred to as good cholesterol)
LDL: 80 and the optimal range is 80-130 (referred to as bad cholesterol)


These numbers definitely suggest that for some a ketogenic diet does not increase cholesterol levels. The good news is I not only see differences on the outside, but also on the inside.
