Total cholesterol is not the best marker to look at because it does not take into consideration the composition of the cholesterol. The ketogenic diet has been shown to increase HDL (good) cholesterol, which would lead to an increase in total cholesterol but would be beneficial overall. Be sure to have your doctor check the breakdown of your blood lipid tests and look for better markers, such as VLDL,LDL-to-HDL ratio, triglycerides, and even high sensitivity CRP (not traditionally part of cholesterol panel, but can be measured with an NMR Lipoprofile test).
