Should you worry about your cholesterol on a keto diet?

Are your cholesterol values problematic and something to worry about?

Dave Feltman, who runs the site Cholesterol Code, has made a video where he goes through a standard cholesterol test and what it means on a keto diet:

    I started Keto about 2.5 weeks ago and did a blood test. Below are my results after the test and having been on keto for 2 weeks.

    HDL - 52; Triglycerides - 110 and LDL - 242

    Now this is significantly different from my results February which are as below:

    HDL - 39; Triglycerides - 192 and LDL - 149

    Should I be worried?

    I see your HDL ("good" cholesterol) has gone up. :)
    I see your Triglycerides have gone down. :)

    I'd say 2.5 weeks of a complete dietary lifestyle change is probably not long enough to draw any conclusions. Test again in 6 months. Watch the videos linked on this page, especially "Why high cholesterol is healthy"

    Good luck and stick with it!

    I have been doing "lazy" keto for over a year. I have lost 45 lbs and I am down to the weight I was when I got married 20 years ago! I do NOT want to stop! However, my doctor is making me nervous worrying about my cholesterol. A little family history, my mom had 4 heart attacks and died at 53, my dad died from a heart attack when he was 56; I am 43.
    These are my numbers:
    Total - 243
    HDL - 71
    LDL - 156
    Triglycerides - 56
    CHOLl/HDLC ratio - 3.4
    non-HDL cholesterol - 172
    Should I be worried? What can I tell my doctor if he wants me to stop or go on cholesterol meds?
