Physicians everywhere want to “fix” your
“cholesterol.” They’re well meaning, and they know there is a very small
benefit, probably due to a reduction in inflammation. But only if have known
CVD, and you’re male and under age 65. They know that by lowering your Total Cholesterol
(TC), your LDL will be lowered by the
same amount. And they know they can do that with a pill. They can get your
LDL to within the range recommended by the pharmaceutical industry’s “Standard
of Practice” by prescribing a statin drug: Crestor or Lipitor or Zocor, or one
of the popular generics like simvastatin. So, what’s wrong with that? The
answer: it’s the wrong target!
In the first place, lowering LDL Cholesterol is
by far the most common intervention for which your doctor can write a “script”
(prescription). That’s why they do it. It must be frustrating for them though,
since “high cholesterol” (meaning high Total Cholesterol and LDL) is almost
always associated with low HDL and
high triglycerides. They are all so common in the same patient. The
result, however, is that sales of statins in the U.S. since they were
introduced in the 1980s have skyrocketed. Meanwhile, HDL and triglyceride
levels have remained unchanged.
It must be doubly frustrating that “high
cholesterol” is commonly associated with hypertension (high blood pressure) and
obesity. Collectively these are all among the indications of Metabolic
Syndrome. See Retrospective #9 for specifics. The particular cholesterol markers
associated with Metabolic Syndrome are low HDL and high triglycerides. The medical
term for this cholesterol condition is “dyslipidemia,” or dysfunctional blood
lipids (fats).
Although progress is being made in treating high
triglycerides, unfortunately there is no pill to beneficially raise HDL. But dietary intervention works for both
of these. See Retrospective #67 “HDL Cholesterol and the Very Low Carb
Diet,” and Retrospective #68, “Triglycerides, Fish Oil and Sardines,” and then Retrospective
#27, “…the strongest predictor of a heart attack” for the CVD benefits of dietary
intervention for both triglycerides and HDL.
Of course, hypertension can be treated
with medications, usually a “cocktail” of two or three. Obesity, however, stubbornly
resists medical interventions. It is up to the patient, the doctors say, and the
doctors usually report the patient is “non-compliant.” That is, the patient either
cannot lose weight on the medically-recommended restricted-calorie BALANCED diet, or the
patient who does lose weight soon gains it all back and often “then some.”
Hunger wins out. The body, which can’t
access its own fat reserves on a high-carb diet, doesn’t want to be starved.
When it needs energy, it tells you to eat food-by-mouth for that energy, whenever
your blood runs low on glucose.
So “high cholesterol” and hypertension, commonly seen
together, are still the targets that most doctors treat together. The problem
is: Total Cholesterol is an antiquated and almost useless term. It is only used
because it can be easily measured and lowered by statins. HDL and triglycerides
remain unchanged. But a Total Cholesterol that would be “too high,” because of its LDL component, would be perfectly
okay with your doctor if the LDL was lower but the HDL was much higher and
the triglycerides much lower. If that seems confusing, see Retrospective
#25, “Understanding Your Lipid Panel,” for two identical Total Cholesterols
with different HDL, LDL and TG components.
The reason for this is evident from the formula that
was used for 30 years and until recently) for the lab cholesterol test: the Friedewald
formula. In it, Total Cholesterol and HDL and triglycerides are assayed
(actually measured), but the LDL value was calculated: LDL = TC – HDL –
TG/5. A revised formula, Martin/Hopkins, used since Summer 2018, still also
uses a calculated LDL, not a direct measurement. It does continue to assay
HDL and triglycerides directly.
So, if the
best way to “fix” your cholesterol is to raise your HDL and lower your
triglycerides, you can do that –
by following a restricted-calorie Very
Low Carbohydrate diet. You will also lose weight easily and without hunger because
your body will be free to
burn your body fat. And you will get control of your blood sugar (if you
need to), and lower your blood
pressure. Your Type 2 diabetes (if you have it, or you’re pre-diabetic) will go
into remission.
Your doctor can’t do these things by prescribing
statins and blood pressure pills, but YOU
CAN. But first you have
to know about your cholesterol. Read Retrospectives #9, #25, #27 and #67 and
#68 and take charge of your health.
