I donate blood about every 3 months and here at the San Diego Blood bank they take all of your vitals (and post them online in your account foe for you to view) iron levels, blood pressure, pulse and cholesterol. My Cholesterol was 199 before I started eating primal. Three months later my levels turned out to be 186. Three months after that (last week) my levels are now at 165.
I would say to give it time, it wasn't an over night situation for me. On a side note my co-workers couldn't believe it when they see me eating steak and eggs plus bacon nearly every morning.
