I'm totally new here, just discovered this site today... Am kind of worried because I started eating LCHF in August, after some 30 years of high carb (wholegrains and mainly vegetarian), very Low fat (and then mainly MUFA's). However, over the last 5 years or so, I gradually got to eat more and more bread, homebaked pastries and cakes and honey. I noticed that energy levels dropped dramatically after breakfast, especially when this includes either bread or oatmeal porridge! So, since I am living in Sweden, I read a lot about this LCHF trend... And decided to try it out. I have no weight issue (47.5 kg for 1.60m . In October I had bloodtest and wow, it really frightened me: TC 241, HDL 77, LDL 151, TG 63 and TC/HDL 3.1 Never ever has my TC and LDL been so high! Should I stop eating Paleo/Lchf? Btw, I do have incredible energy again though and no longer have this lethargic post-carb feeling...

First off, I think it's a great idea that you're going low carb.
While it's still a good idea to review everything with your physician, there are good points to your numbers.
HDL - 77 - This is very good. TG - 63 - Also very good. This shows that you're not eating very many carbs, because when you eat a lot of carbs, they get converted to triglycerides.
TG/HDL ratio - yours is 1.22 which is good. (Ideally it is less than 2).
A really good book to check out is "The Art and Science of Low Carbohydrate Living" by Volek and Phinney
They have a really good chapter describing similar changes in the standard lipid profile with low carb high fat diets.
There is a lot of data out there now that show that the standard LDL level is inadequate. There are two types of LDLs that they can test for, the Pattern A (fat and fluffy) and Pattern B (small and dangerous) types. Only the Pattern B LDL is associated with a higher risk profile.
Another important question to ask if if you've been losing weight, or more importantly losing fat on this diet. This can cause your body to mobilize your fat stores, causing a temporary elevation in your LDL.
Again I think you should take a good look at the book above.
I'm in the midst of doing my own low carb high fat experiment, checking my weight, blood ketone levels, and blood sugars every day. I took a blood test before this experiment, and will do one after 60 days.

Everything the previous posters said, plus: LDL-C is an estimate (Friedewald formula) that works with TG > 100.
Furthermore, TC is somewhere between useless and mildly correlating.
Highly speculative: You damaged your body in the past and now the heavy cholesterol transport is necessary for repair (for possible reasoning, cf. Seneff et al., 2010, American Medical Science).

Take a deep breath; there is no reason to be so frightened. First of all, an LDL of 151 is only considered to be "borderline-high." Second of all, what you really want to know is your LDL-P which measures the number of LDL particles and is now considered to be a better measure of risk. With your lipid numbers, there is a decent chance that your LDL-P will put you in an even lower risk category than your LDL-C. Bottom line, get an NMR test which will give you your LDL-P. (You can disregard anything to do with particle size since, despite the information given out on these forums, even folks with many large particles (eg familial hypercholesterolemia) get heart problems.)
If you decide to get the NMR test, you can report back here if you like to see what you might do nor not do as the case may be.

Dude i eat close to a dozen eggs a day somedays. I'm not exaggerating. Cholesterol is fine, you won't develop heart disease cause you eat a lot of it. It is necessary to produce hormones. It only a problem when you eat a high carb/SAD diet. If you're not eating any grains, legumes and conventional dairy, sugars and vegetable oils, you're good. Eat as as much as you like. The same with saturated fats. Don't fear fat and cholesterol.

Another book that will put your mind at ease is "The Great Cholesterol Myth" by Bowden and Sinatra. In this book you will learn that elevated total and LDL are NOT predictors of cardiovascular risk. 50% of people who have heart attacks and strokes have NORMAL or LOW cholesterol.
As mentioned Above, better predictors of cardiovascular risk are particle size, particle number, and CRP which you didn't have tested.
Your HDL and triglycerides are great, and he best way to keep them good is exactly what you are doing--a low carb Paleo diet.
You're doing great! Hang in there.
