Hi there, first time posting here.
I've had my first post-primal diet blood results back and the nurse was quite concerned about the massive jump in my cholesterol. To be honest, I kind of expected this and I'm not in panic mode but I'd like to see what other people make of my results.
Based on my own research, I think there is room for improvement but overall my results aren't something to worry about.
When speaking to the nurse, after asking her what she made of my results in terms of heart disease risk (this is in the UK, so based on NHS guidelines), she said initially that it would be deemed high risk but taking a holistic view of my overall health, recent weight loss and activity level, she said that I probably have nothing to worry about.
So, before I post the results, a little bit of background...I started eating a primal diet back in January, at a calorie deficit and very low carb (< 50g/day) in order to lose weight. This has put me in a state of ketosis for much of the last 6 months. I also intended to make the diet change a permanent one if it worked for me and so far I'd say it has.
Since January, I've lost 38lbs, dropping from 213lbs to 174lbs at a height of 5'11", a change on the BMI scale from 31+ to 24. I feel healthier and I'm happy with my weight loss. This was all achieved through my diet changes. I started lifting weights a month ago and started running again last week.
The bulk of my diet is meat, eggs and vegetables with a small amount of nuts and fruit and starches like sweet potato. I eat lots of greens. I don't get hung up about saturated fat and enjoy small amounts of full fat milk in my tea, double cream with my fruit, some cheese and full fat yogurt and I like to cook in a mixture of butter, ghee, coconut oil and olive oil depending on what I'm cooking.
I've cut grains out of my diet completely (I did eat the occasional bowl of oats in the first few months), most sugars (I still enjoy the occasional glass of red wine and some 85% cocoa dark chocolate) and all vegetable oils for the most part (I may occasional consume small amounts in the small amount of convenience food I eat, but generally I'm very careful about what I eat).
On to those results...(results in mmol/L, converted to mg/dl in parens)
Total cholesterol: 6.2 (240) Serum triglycerides: 0.97 (86) Serum HDL: 0.99 (38) Serum LDL: 4.8 (185) Total/HDL ratio: 6.26 HTL/LDL ratio: 0.2 Trigs/HDL ratio: 2.05
As you can guess, the nurse was concerned about the total and LDL levels. The LDL does seem high and I'm sure my HDL could do with being a bit higher but the trig levels look good.
For comparison, here is the results of my blood test from December 2011, a month before changing my diet (no trigs or LDL as it was not a fasted test):
Total cholesterol: 4.3 (166) Serum triglycerides: N/A Serum HDL: 0.78 (30) Serum LDL: N/A Total/HDL ratio: 5.5
What do you think? Am I on the right course with my diet? Could I do with cutting back the saturated fat a little? I intend to move my carbs closer to the 100g/day mark once I hit my weight loss goals and scale back some of the fat to accomodate but I'll still be eating a largely high fat/moderate protein/low carb diet.
Looking forward to hearing people's opinions.

luke, your results for LDL is based upon the Friedewald formula and is an estimate of the serum LDL. The Friedewald formula has been shown to be fairly accurate (and cheap since it's just a linear equation) for people with trigs between 110 and 350. Your Trigs are outside of the accepted bounds for the Friedewald formula.
In comparison, the Iranian formula (which is designed for trigs in 50-100 or 350-450) would suggest that your LDL is 174 (sorry I work in mg/dL you can convert back). That would put you on the low end of "high".
The first thing I would do is demand a direct measure of your LDL and VLDL levels. Once you know what your actual results are (i.e. not what a formula tells you) then you can discuss potential next steps with your doctor.

Your total blood cholesterol is not high, the doctor is wrong. Lowest all-cause mortality risk in between 200 and 240mg/dl total cholesterol: http://3.bp.blogspot.com/-pttFtp8eZx0/T3IFYTDzEwI/AAAAAAAAAQ8/Grmm-gHD1yI/s1600/CholesterolMortality.jpg

are you still losing weight on Primal/Paleo?
Blood lipids are going to be high when you're breaking down adipose tissue or using fat for energy.

Meats contain high levels of cholesterol. When I considered being vegan before switching to a mainly paleo diet, I read a lot about the negative aspect of meat, mainly that it has high amounts of cholesterol that your body does not need.
