Be prepared for the blood work. If you maintain a high meat, eggs and fish diet and limit Omega 6, your health will improve, your tricycerides will drop and your HDLs will go up. Good so far. However, your LDLs ("bad" cholestrol) may go up as well. This will send up a red flag for your doctor. Just say "yes sir," nod politely, then do what you know is best. There is no proven link between high LDLs and heart desease although conventional medicne says otherwise.
Further to this, this blog explains the "reason" your LDL's may appear to go up.

Basically the LDL level is a calculated number and it doesn't work for people with high HDL and low trigicerides, like most people on low carb diets.
