Long-term adherence to Dr. Kwaśniewski’s Optimal Diet: Healthy with high LDL cholesterol

This is a research (Grieb, P. et al., 2008 entire reference at the stop of this put up) that I go through a handful of many years in the past, correct following it arrived out, and at the time I recall pondering about the clear contradiction among the constructive results of the Ideal Diet plan and the extremely elevated LDL cholesterol ranges among the contributors. I say “contradiction” simply because of the proven and misguided dogma amongst health care doctors, notably common practitioners, that lowering LDL cholesterol levels is the ideal method to avoid cardiovascular disease.

The Optimum Diet program is 1 of the best examples of a healthy diet plan exactly where LDL cholesterol stages are generally large, in reality a lot larger than most folks are prepared to accept as healthful today. (In this research, LDL cholesterol levels have been calculated primarily based on the Friedewald equation.)

It is not uncommon to see people concerned about their substantial LDL cholesterol stages following adopting a reduced carbohydrate diet. (A reduced carbohydrate diet program is, generally speaking, a higher body fat diet program.) This review shows that this is a instead common thing, and also that it is not one thing that those who encounter it should be too concerned about. To be persuaded of this, one particular can usually do a VAP take a look at (see this publish for a url to a sample VAP test report) and verify his or her LDL particle sample.

The study provides the Best Diet regime as the Polish equal to the Atkins diet regime. It states that the Diet’s main characteristic is preserving the proportion of proteins:fat:carbs. in the assortment of one:2.5-3.five:.5, with no restriction on the amount of food eaten. In truth, as you will see in this put up, more than 70 percent of the energy consumed by the review participants arrived from excess fat.

Effortlessly digestible carbohydrate-rich meals are not part of the Optimal Diet plan. Far more specifically, the pursuing food items have been outlined as not getting permitted in the Best Diet plan: sucrose, sweets, honey, jam, white rice, bread, starches in general, beans, potatoes (only in small amounts), and sweetened drinks. Also, the Best Diet plan is undoubtedly a low carbohydrate diet regime, but not what is usually referred to as a "really reduced carbohydrate diet regime". In this review, the typical carbohydrate consumption for each day was all around sixty g.

Thirty-1 wholesome people participated in the research, 17 ladies and 14 men. The average age was 51.7 (standard deviation: 16.6). They had self-reportedly adhered to the Optimum Diet program for at least one year prior to the review the common period of time of adherence was 4.one several years (standard deviation: 1.9). So, the huge majority had been on the diet for much more than 2.two many years, about 50 % for 4.one a long time or a lot more, and about 1-sixth for a lot more than 6 years. (Examine this submit if you want to know how these figures can be calculated primarily based on the regular period of time of adherence and the standard deviation.)

The table beneath (simply click on it to enlarge) displays anthropometric and physiologic attributes of the individuals. Note that for a longer time adherence to the Optimal Diet (appropriate finish of the table) was linked with lower systolic and diastolic blood force, as nicely as reduced physique mass index (BMI). (It was also connected with lower height and BMR, so I am guessing that more women tended to be prolonged-expression adherers than gentlemen.) Most of the individuals experienced BMIs in the normal variety, with only one particular in the overweight class. That was a forty three-year-old male who followed the diet for 1.five a long time he had a BMI of 34.one.


The macronutrient distribution of the Optimal Diet program is revealed on the desk beneath (click on on it to enlarge), as followed by the members. As you can see, protein intake was not that large about fifty three.9 g for each day on common for gentlemen, a little bit considerably less for women. Notice the share of energy from excess fat: a lot more than 77 p.c for men and 72 percent for females. Given the BMIs just talked about, 1 can properly say primarily based on this that taking in a lot of unwanted fat did not make the contributors body fat.


The table below (click on on it to enlarge) has some interesting overall health markers. Observe that cost-free fatty acids (FFAs) were elevated. This is to be anticipated, as these individuals were burning fat for power most of the time, and not as much glucose. The FFAs are not really “free”, but bound to a protein known as albumin, which is considerable in human blood. FFAs yield huge portions of adenosine triphosphate (ATP), the major vitality “currency” employed by the entire body.


These ranges of FFAs are also typically connected with moderate ketosis, the place ketones are created by the human body and used for strength. Not like albumin-bound FFAs, ketones are soluble in drinking water, and as a result flow into freely through the blood. The moderate ketosis skilled by the contributors was possibly to the point the place ketones confirmed in the urine. The write-up mentions this, and offers a evaluate of beta-HB (beta-hydroxybutyrate, a ketone entire body), which is elevated as envisioned, but does not give urine or other blood ketone steps (e.g., blood acetone stages). Also be aware the reasonably wholesome fasting glucose amounts, slightly higher in men than in ladies, but pretty low overall. Reasonably healthier insulin amounts as well at the high end of what Stephan at Complete Health Supply would advocate, but even now considerably reduce than the average insulin amount in the U.S. at the time of the article's publication.

Lastly, the table below (click on it to enlarge) exhibits lipids and a couple of other steps. Whole cholesterol was on average a bit a lot more than 278 mg/dL. LDL cholesterol was a little bit greater than 188 mg/dL on average large ample to make most medical professionals cringe nowadays. Primarily based on the implies and regular deviations presented, we can estimate that about sixteen per cent of the members experienced LDL cholesterol stages increased than 228.one mg/dL. About 2.five p.c of the participants experienced LDL cholesterol amounts increased than 268 mg/dL. And this is all right after adhering to the diet plan for a relatively extended time period of time even larger LDL cholesterol amounts might have transpired proper after adoption.


Nevertheless common HDL cholesterol was a extremely higher and protecting seventy one.six mg/dL. This higher HDL and the relatively lower triglycerides advise a big-buoyant non-atherogenic LDL particle pattern.

Common HOMA(IR), a measure of insulin resistance, was a reduced 1.35 mU/mmol strongly indicating, collectively with the fairly low fasting glucose stages, that the individuals ended up considerably from being pre-diabetic, enable by itself diabetic.

Diabetic issues is a powerful risk issue for cardiovascular condition, and many other health problems significantly far more so than elevated LDL cholesterol.

The Optimum Diet does not appear to be a diet program for bodybuilders, but I would say that, total, Peter at Hyperlipid has decided on a diet that can make some feeling.
