>Sadly, the world of lipid disorders has been reduced to prescribing a statin drug and little else, 9 times out of 10.
I don't mean to rant, but I continue to be shocked at the incredible influence the drug industry has over not just prescribing patterns, but thinking patterns. Perhaps I should say non-thinking patterns. The drugs make it too easy to feel like the doctor is doing something when, in truth, they are doing the minimum (at best) and missing an opportunity to provide true health-empowering advice that is far more likely to yield maximum control over these patterns with little to no medication.
All in all, I am grateful that there is a growing discipline of "lipidology," a specialty devoted to diagnosing and treating hyperlipidemias. Unfortunately, much of the education of the lipidologist is too heavily influenced by the pharmaceutical industry. Not surprisingly, the drug people favor "education" that highlights their high-revenue products.
Seeing a lipidologist is still better than seeing most primary care physicians or cardiologists. Just beware that you might be walking into the hands of someone who is simply the unwitting puppet of the pharmaceutical industry.
I have to say: I'm impressed. If you would like insight into why a "Paleo" nutritional approach works on a biochemical level--why you lose weight, burn fat, and gain overall better health--then Robb's book is worth devoting a few hours to, of not a reread or two.
Robb has a particular knack for organizing and presenting information in a way that makes it immediately accessible. You will gain an appreciation for how far American nutritional habits have veered off course.
Because Robb brings expertise from his academic biochemistry background, as well as personal trainer and educator running a successful gym in northern California, NorCal Strength and Conditioning, he delivers a book packed with information that is extremely easy to convert to immediate action in health and exercise. He seems to anticipate all the little problems and objections that people come up with along the way, dealing with them in his characteristic lighthearted way, providing practical, rational solutions.
If nutrition has you stumped, if the USDA food pyramid still sounds like a reasonable path, or if you just would like to understand nutrition a little bitter, especially its biochemical ins and outs, Robb's book is a wonderful place to start.
If you want to make foie gras, you feed ducks and geese copious quantities of grains, such as corn and wheat.
The carbohydrate-rich diet causes fat deposition in the liver via processes such as de novo lipogenesis, the conversion of carbohydrates to triglycerides. Ducks and geese are particularly good at this, since they store plentiful fats in the liver to draw from during sustained periods of not eating during annual migration.
Modern humans are trying awfully hard to create their own version of foie gras-yielding livers. While nobody is shoving a tube down our gullets, the modern lifestyle of grotesque carbohydrate overconsumption, like soft drinks, chips, pretzels, crackers, and--yes--"healthy whole grains" causes fat accumulation in the human liver.
Over the past few years, there has been an explosion of non-alcoholic fatty liver disease and non-alcoholic steatosis, two forms of liver disease that result from excess fat deposition. The situation gets so bad in some people that it progresses to cirrhosis, i.e., a hard, poorly-functioning liver that paints a very ugly health picture. The end-result is identical to that experienced by longstanding alcoholics.
While Hannibal Lecter might celebrate the proliferation of human fatty livers with a glass of claret, fatty liver disease is an entirely preventable condition. All it requires is not eating the foods that create it in the first place.
When it's visceral fat. Visceral fat is the fat that infiltrates the intestinal lining, the liver, kidneys, even your heart. It's the stuff of love handles, the flabby fat that hangs over your belt, or what I call "wheat belly."
Unlike visceral fat, the fat in your thighs or bottom is metabolically quiescent. Thigh and bottom fat may prevent you from fitting into your "skinny jeans," but its mainly a passive repository for excess calories.
Visceral fat, on the other hand, is metabolically active. It produces large quantities of inflammatory signals ("cytokines"), such as various interleukins, leptin, and tumor necrosis factor, that can trigger inflammatory responses in other parts of the body. Visceral fat also oddly fails to produce the protective cytokine, adiponectin, that protects us from diabetes, cancer, and heart disease.
Visceral fat also allows free fatty acids to leave and enter fat cells, resulting in a flood of fatty acids and triglycerides (= 3 fatty acids on a glycerol "backbone") in the bloodstream. This worsens insulin responses ("insulin resistance") and contributes to fatty liver. The situation is worsened when the very powerful process of de novo lipogenesis is triggered, the liver's conversion of sugar to triglycerides.
Visceral fat is also itself inflamed. Biopsies of visceral fat show plenty of inflammatory white blood cells (macrophages) infiltrating its structure.
So what causes visceral fat? Anything that triggers abnormal increases in blood glucose, followed by insulin, will cause visceral fat to grow.
It follows logically that foods that increase blood glucose the most will thereby trigger the greatest increase in visceral fat. Eggs don't lead to visceral fat, nor do salmon, olive oil, beef, broccoli, or almonds. But wheat, cornstarch, potato starch, rice starch, tapioca starch, and sugars will all trigger glucose-insulin that leads to visceral fat accumulation.
Fructose is also an extravagant trigger of visceral fat. Fructose is found in sucrose (50% fructose), high-fructose corn syrup, agave syrup, maple syrup, and honey.
Increased visceral fat can be suggested by increased waist circumference. The inflammatory hotbed created by excess visceral fat has therefore been associated with increased likelihood of heart attack, cardiovascular mortality, diabetes, cancer, and total mortality.
So I'm not so worried that you can't squeeze your bottom into your size 8 jeans. I am worried, however, when you need to let your belt out a notch . . . or two or three.
Gwen came to me 5 years ago. In her late 60s, she'd been having feelings of chest pressure for the past 4 weeks with small physical efforts, such as climbing a flight of stairs or lifting her grandchildren.
She sat in my office, heaving small sobs, accompanied by her daughter.
Gwen had already undergone a heart catheterization at a hospital near home by a cardiologist who I knew to be honest and competent. She'd been told that she had a 90% stenosis ("blockage") of her proximal left anterior descending (LAD) coronary artery. He called it a "widow maker," since closure of the artery at this point can be fatal within minutes. He advised bypass surgery as soon as possible. Though a stent could be placed at this location, he felt that its proximity to the left main stem (i.e., the "trunk" that divides into the LAD and circumflex arteries) might be jeopardized by expanding a stent in this bulky plaque, what I felt was a reasonable concern.
I reviewed the images that she brought with her. Yes, indeed: a widow maker. The portion of the left ventricle (heart muscle) fed by the LAD was also impaired ("hypokinetic"), reflecting reduced flow through the artery.
I advised Gwen that her first cardiologist's advice was sound: This was a potentially dangerous and severe condition. Either a bypass or stent should be performed near-future, the less delay the better.
But Gwen and her daughter would have no talk of any more procedures. She'd come to me because she heard about the (then rudimentary) effort I'd been making at reversing coronary plaque. "I admire your commitment, Gwen, but I am concerned that there may not be sufficient time to implement a program of prevention or reversal. Prevention is very powerful, but very slow. When symptoms like yours are active, also, it can mean that we won't have full control over the plaque causing the symptoms. This risks closure of the vessel, since flow characteristics in the plaque are abnormal. I think that you should go through a stent or bypass. We can then start your prevention/reversal program once we know you're safe."
Gwen would still have none of it. I asked her to return in a few days after thinking it over. In the meantime, we drew her lipoprotein blood samples while she added fish oil, l-arginine (back then I used a lot of l-arginine for its endothelial health effects), and began the Track Your Plaque diet a la 2004. This was in addition to the aspirin, beta blocker, and statin prescribed by the first cardiologist.
Several days later, Gwen and her daughter returned, as committed as ever to not having a procedure and proceeding with our prevention/reversal efforts.
So off we went. I was nervous about Gwen's safety, but she had clearly made her mind made up. Gwen's lipoprotein analysis revealed a severe small LDL pattern along with markers for prediabetes (high insulin, high blood glucose, hypertension, along with the loose tummy of visceral fat). So I counseled her intensively in diet and added niacin.
Within 2 weeks, Gwen no longer had chest pain. Whether this was due to her efforts or to some resolution of an intraplaque phenomenon (e.g., resorption of internal plaque hemorrhage), I don't know. But her symptoms did not return.
As the program evolved, we added the new strategies along the way--vitamin D supplementation; elimination of all wheat along with other changes in diet; iodine and thyroid normalization; as well as discontinuing l-arginine after the initial two years. She also got rid of the statin drug after losing around 20 lbs on the diet.
It's now been six years with her "widow maker" and Gwen has been fine: no recurrence of her symptoms, all stress tests performed have been normal, reflecting normal blood flow in her coronary arteries.
Should ALL people with symptomatic widow makers undergo such an effort and avoid procedures? No, not yet. Prevention and reversal efforts are indeed powerful, but slow. Some people just may not have sufficient time to accomplish what Gwen did. The fact that Gwen showed evidence for reduced flow in the LAD worried me in particular. There is no question that mortality benefits for stenting or bypass of this location are not as large as previously thought (see here, for instance), but each case needs to be viewed individually, factoring in flow characteristics in the artery, appearance of "stability" or "instability" of the plaque itself, not to mention commitment of the person.
I just had a workout with personal trainer and fitness expert, Fred Hahn. After a workout that quickly taught me that I had a lot to learn about exercise and strength training, Fred and I had a nice low-carbohydrate dinner at a Manhattan restaurant and shared ideas.
I had heard about Fred's "slow-burn" concept in past, but made little of it. I then met Fred on Jimmy Moore's low-carb cruise this past year, where I gave a talk on how carbohydrate-reduced diets reduce small LDL particles. Fred provided a group demonstration on his slow-burn techniques. I watched the demonstration, even tried it a few times back home in the gym, but never really applied them, losing patience most of the time and just going back to my usual routine.
Well, Fred showed me today how to do his slow-burn. In a nutshell, it is the slow, methodical use of weight resistance until the muscle is exhausted. It involves slow movement--e.g., 5 seconds for a lat pulldown from top to bottom--repeated until exhaustion using a weight that allows, perhaps, 6 repetitions over a 60-second effort.
I've been strength training since I was a teenager. I've seen lots of bad training techniques, injuries, and hocum when it comes to how to use resistance training techniques. But I believe that Fred Hahn's slow-burn technique really provides something unique that I hadn't experienced before.
For one, the burn is nothing like I've felt before. Two, there appears to be nearly zero risk for injury, since the usual momentum-driven, herky-jerky motion often employed with weight machines is entirely gone. Three, if what Fred is seeing is true--enhanced visceral (abdominal) fat loss, reduced blood glucose, increased HDL, decreased LDL/total cholesterol--then there's something really interesting going on here.
I also discovered that Fred is no ordinary personal trainer. He has insights into metabolism that I found truly impressive. After all, he's been hanging around with Mike Eades, who's a pretty sharp guy. What Mike Eades is to metabolic insights is what Fred Hahn is to exercise physiology.
I'm going to take Fred's slow burn training insights home with me. I'll let you know how it goes. Some aspects I'd like to explore: Will strength, muscle mass, and blood sugar responses change?
