There are only 3 tests that I had done.
Vitamin D level, which is at goal after 6 weeks on 5000 mg/day so I may cut this down a little to 2000-3000 mg/day.
Hemoglobin A1c was just a tiny bit lower than last time down from 5.9 to 5.8, technically still in the pre-diabetic range, nowhere near the level of 5.0 that I would like to see.
Given that I did not lose any more body fat and have gained a little weight since I started exercising more again I have to assume that I am still insulin resistant to some degree. I may have no choice but to cut the carbs down even more if I want to lose more body fat. I will give it a try for a little while, maybe 2 weeks, to see if I can keep my net carbs under 20. My hope is that if this works that I can maintain on more than that.
The biggest surprise (for me, not my doctor) was the result from my cholesterol levels.
My total cholesterol went up from 243 in June 2009 (before low-carb) to 361.
LDL went up from 146 to 227
HDL went up from 89 to 124
Triglycerides went down from 52 to 51
This puts my TG/HDL-C ratio at 0.41.
Let me at this point share a short excerpt from Peter Attia's blog, who has described the significance of cholesterol in his post "How a low-carb diet reduced my risk of heart disease (Part 3)":
"Combining HDL-C and TG into a ratio (i.e., TG/HDL-C) is probably the single best predictor of cardiac risk you can derive from a standard cholesterol test. The lower the ratio, the lower your chances of having an “adverse cardiac event,” as the medical community describes it (e.g., a heart attack). Despite what doctors tell you, LDL-C is pretty much useless for predicting your risk of heart disease. In fact, it’s not even part of the risk assessment for metabolic syndrome, which everyone agrees is the central link to heart disease (and virtually all other chronic diseases we’re afflicted with)."
He then goes on to explain that there are better tests to determine risk, including a test that measures particle size, something I may look at having done at some point.
I have to say that high LDL cholesterol levels run in my mother's side of the family so I don't know if the cause is a low-carb diet. Either way, I have not had a chance to talk with my doctor yet but from her remarks she does not seem to be concerned (she is fully on board with low-carb eating). Her comment was "Continue as you are (with low-carb) and I 'll see you in 3 months (to check body fat percentage)". I am so thankful I found this physician because I know that most physicians would have immediately insisted that I start taking statin drugs and go on a low-fat, low cholesterol diet. Thankfully I had plenty of time to do my research and know that the cause of heart disease is not high cholesterol levels but inflammation, which is caused by too many carbs.
Just in case I needed some extra information on the topic, a book that I ordered just a few days ago came in the mail a week earlier than expected:
Please take a quick look at the reviews for this book. I'm very happy with my purchase so far.
So overall I feel I'm moving towards better health, even though I feel a little like pouting because I have to give up my little Xylitol and fruit treats, at least for a while.
I am also beginning to realize that the fact I had to take 2 months off from running late in the summer because of surgery means that my cardio fitness went in the tank a little. My resting pulse was up from about 60 what it was in August to about 70 now. But I know what to do to fix it, running 5-6 times/week at an easy pace. At least I'm carrying a few pounds less than I did a year ago when I was preparing for the same Half marathon.
