The most important weight loss tool 4. March 2010 William Davis (15) Question: What is the most effective tool available to help you lose weight? A pedometer (walk 10,000 steps, etc.)?A treadmill? A bicycle?No. None of the above. Toggle navigation Home Blog Home Archive Join Now Log in Report from Washington II 16. July 2006 William Davis (0) Today's discussions at the Society for Cardiovascular Computed Tomography (SCCT) focused on atherosclerotic "plaque characterization".As CT scanners get better and better at imaging the various components of plaque, some fascinating issues emerge:--CT heart scans provide insights into what exactly is contained in an individual's atherosclerotic plaque that are not often provided even during heart catheterization. In other words, CT heart scanning is, in many instances, superior to heart catheterization, since it provides images of the artery wall, not just the internal contents. --Progression (i.e., increase) in heart scan score is a powerful predicter of heart attack risk. Dr. Matthew Budoff of UCLA argued persuasively that the annual rate of increase in score is probably the most accurate measure of risk available, superior to cholesterol and calculated measures like the Framingham risk score. --Coronary calcium scoring remains the best method to gauge total plaque throughout the entire coronary tree. In a person free of symptoms, the risk of a cardiac "event" (heart attack, death, procedures) is low and additional imaging (like CT angiography) is generally unnecessary. Dr. Budoff, among the true thought leaders in CT heart scanning, also recounted his perspective on the history of heart scans. He noted that the questions asked through the years have evolved:1995-2000 Should we do coronary calcium scans?2000-2002 Do high or low risk patients benefit from coronary calcium scoring?2003-2004 What is the better scanner, EBT or MDCT?2006 How often should we perform coronary calcium imaging?I believe that Dr. Budoff summarizes wonderfully where the Track Your Plaque programs fits into the overall scheme of things: Serial (repeated)CT heart scans to gauge progression or reversal is the wave of the future. We shouldn't just be interested in identifying persons at risk for heart attack. We should also be interested in showing the person at risk exactly how to reduce or eliminate that risk. Report from Washington 14. July 2006 William Davis (0) I'm presently attending the Society for Cardiovascular Computed Tomography meetings in Washington, DC, along with 500 of my colleagues. It's exciting to see how interest in CT scanning for heart disease has balloonned in the past couple of years.Several trends are noticeable today, based on the content and tone of the discussions:--CT scanning of the heart, and imaging in general, is just getting started. In other words, the capabilities for CT scanners and other devices to detect heart disease (coronary and otherwise) are where the gasoline engine was in the 19th century. Scanning is getting faster, easier, safer, and more precise. Just as few people in 1905 could have predicted that automobiles would be computer-enhanced, high-speed, ubiquitous devices with several per household, the potential for CT imaging for heart disease is truly in its infancy. --CT coronary angiography (so-called "64-slice CT scans") are not screening tests for hidden coronary disease in people without symptoms. I was grateful that this point has been made and reiterated by several speakers, as this is consistent with our views. Simple CT heart scans for coronary calcium scoring, in contrast, are screening tests. When the radiation exposure of CT angiograms are reduced to tolerable levels, then they may be used as screening tests. We are probably 3-4 years away from this point. --Both stress testing and heart catheterizations will be partially replaced by CT scanning. In particular, over the next decade, you will see a dramatic drop in unnecessary catheterizations, i.e,, far less people saying "I had a heart cath but they told me that it was normal."There has been heavy focus on applications of CT scanning for acute settings, particularly the emergency room and hospitals. What has surprised me is that there is virtually no conversation whatsoever about the preventive uses of CT heart scanning. So far, only Dr. Daniel Berman of UCLA has shown that he has "seen the light": CT scans are a crucial tool for identification of early coronary plaque, and this tells us whether prevention is necessary and with what intensity. There has been, however, no discussion at all about quantification of plaque in a program of reversal. Perhaps that should come as no surprise, given the imaging-technology focus of this convention. For most of my colleagues, prevention is also not terribly interesting. Identification and treatment of acute disease like impending heart attack is. Of course, applying the information from your CT heart scan to empower you in a program and reversal is what the Track Your Plaque program is all about. I hope you see the light. I admit that it's not always easy to follow what we are advocating here. Perhaps not too different than telling someone in his horse-drawn buggy that one day he'll be driving a sleek car with onboard computerized mapping, air-conditioning, and micro-chips to modulate engine performance. He's probably tell us we're nuts.I'll continue to update if any news relevant to our interests crops up in these meetings. What about the Track Your Plaque failures? 14. July 2006 William Davis (0) I’d love to tell you that the Track Your Plaque program track record is of 100% success. It’s not. It is very successful. But we’ve had some people who have failed and failed BIG. These are the people who've undergone bypass surgery, received one or more stents, or had heart attacks. Lesser failures are the people who’ve had large, undesirable increases in heart scan scores of >30% in one year. (The expected rate of increase in your heart scan score without preventive efforts is 30% per year, on average.)What can we learn from those failures? There were several characteristics that stand out among this small group:· Non-compliance--meaning they just didn’t stick with it. They started out right but then rapidly lost interest in maintaining all the pieces of the program and neglected their fish oil, niacin, gain weight, etc. Matthew did this and ended up with three stents to his left anterior descending. His slow start was due to skepticism that the program worked and just plain forgetfulness. · Extreme stress--One of our earliest failures was a 38-year old man whose heart scan score doubled in one year, despite doing everything right. But three family members, all close to him, died within the space of six months, including his mother and a brother. I regard this as one of those instances in which we were powerless, unfortunately, though it is a graphic example of the power of unresolved stress and grief. · Having a “better way”--These are the couple of people who were convinced that they had a better way to control their heart scan score. David firmly believed that his two dozen supplements and exercise program would drop his score. Instead, they permitted a 42% increase. Lee relied exclusively on chelation, along with several supplements of his own design. Lee had three-vessel bypass surgery. · Starting too late--Gerome started with a score of 1179, but also was having chest pressure with emotional stress. His stress test was abnormal, with the entire upper half of his heart not receiving blood with exercise on a stress nuclear study (“anterior ischemia”). Gerome received four bypass grafts. Unfortunately, Gerome never really had a chance to engage in the Track Your Plaque program, since his health and safety were in jeopardy as soon as he started. Have we had any big failures of people who did everything right, were compliant, were not subject to extreme stress (more than just job stress, or financial worries), didn’t neglect the basic requirements of the Track Your Plaque program, and had sufficient time (at least 6 months to 1 year)? No, thankfully, we have not. No one who has stuck to the program has had a big failure. Be smarter than your cardiologist 12. July 2006 William Davis (0) “Do you need a stent?”Sad to say, but that sentence condenses the wisdom of over 90% of practicing cardiologists. Prevention of heart disease means take Lipitor or some other statin and cutting the saturated fat in your diet. That’s it. Maybe throw in exercise. Regression of coronary plaque? That phrase has only entered the conversation since the AstraZeneca-supported trial of Crestor succeeded in achieving 8% regression of plaque (Track Your Plaque Members: See News) as demonstrated by intracoronary ultrasound. In other words, in the minds of my colleagues, it can’t be true until a drug company tells them it’s true. It’s beyond me why this brainwashing of otherwise intelligent people has occurred, but it is blatantly evident in practice. Fish oil is another example. The spectacular benefits of fish oil have been known for 20 years. But only recently has it become a “mainstream” practice to recommend fish oil, largely because a drug manufacturer has put a preparation through the rigors of FDA approval (Omacor) and is now marketing directly to physicians. All of a sudden, fish oil is a good thing? No, it’s just achieved legitimacy in the eyes of practitioners because it graces marketing literature. If you’re reading this, you’re likely interested in coronary plaque regression using the only tool available for you to measure, track, and regress coronary plaque: CT heart scans. Intracoronary ultrasound will achieve the same goal, but it is an invasive procedure performed at heart catheterization, involves threading a wire and imaging probe all the way down the artery, involves real risk of tearing the inner lining of the artery, and is costly (around $14,000-$20,000 for the entire package). Do it every year? That’d be nuts. If you’re thinking about coronary plaque regression, using fish oil, concerned about patterns like low HDL and small LDL, aware of the vitamin D deficiency issue as a coronary risk factor, etc., you are far more aware than the vast majority of practicing cardiologists. They are interested in what new brand of anti-coagulant to use during their heart catheterization (because the product representative gushes about the new agent—only $1200 a dose!). Or, they are interested in gaining the procedural skills to put in a new device like a biventricular pacemaker. Regress/reverse coronary plaque? What for?You already know that a conversation about coronary plaque reversal will not be obtained in your cardiologist’s office. Your family practice doctor or internist? Fat chance! Knee arthritis, pap smears, pneumovax inoculations, sore throats, gout, back pain—they’re spread far too thin to know anything more than the most superficial amount about coronary plaque control. Most know nothing. That’s where we come in. That’s our mission: Educate people about the extraordinary tools that you have available to you, all in the cause of control or reversal of coronary plaque. Why am I here? 11. July 2006 William Davis (0) Frank came to the office for an opinion, sent by his (proactive) family physician. "I really don't know why I'm here, to be honest."Two years earlier, Frank had a heart attack, survived and received two stents to his circumflex coronary artery. He now took Zocor and his LDL cholesterol was a reasonably favorable 89 mg, total cholesterol 183 mg. "I walk with my wife every other day. I've been avoiding fish fries. You'll never see me eat fast food."Frank was correct: If we were going to engage in the conventional approach to coronary disease, Frank was on the right track. We would have postponed his next heart attack or procedure by a couple of years. Stroke, aneurysm, and other atherosclerotic manifestations would be set back, likewise, a few years. Would Frank have profound control over his disease? Absolutely not. In fact, his disease had probably advanced a huge amount just in the two years since his stents were placed and he was on his "prevention" program. Without his current effort, his coronary plaque would be expected to grow 30% per year. On Zocor and his modest lifestyle efforts, plaque growth was probably in the 14-28% per year range. So I explained the unique Track Your Plaque approach to Frank. First, we start with a CT heart scan to establish where he was starting. Although he had two stents in his circumflex artery, we still had two other arteries (LAD, right coronary) to score and track. We then attempt to identify all hidden causes of his heart disease and then correct them. Of course, Frank had multiple hidden causes:--HDL too low at 38 mg/dl--Small LDL-severe, in fact, with 95% of all LDL particles in the small category--Triglycerides too high--Excesses of several triglyceride-containing particles (VLDL, IDL)--Pre-diabetes--Frank had both a borderline high blood sugar and a high insulin level. This is a sure-fire stimulus to coronary plaque growth. --A severe deficiency of vitamin D (<20 ng/ml)--An excessivelyhigh blood pressure during exercise--With a blood pressure of 190/102 on the treadmill. There were others(!), but that was the bulk of the causes behind Frank's coronary disease. Once Frank recognized that there was indeed a huge panel of hidden causes for heart disease, not just too much fat in his diet and LDL cholesterol, he jumped into the program head first. The message: The conventional approach is absurdly oversimplified, a certain path to failure for the majority of people. Even if you don't have known coronary disease like Frank, but just have a heart scan score >zero, the same principles apply to yoLDL goes way up, a striking divergence.) This is yet another reason to not rely on this "fictitious" LDL cholesterol value that, inaccuracies notwithstanding, serves as the foundation for a $27 billion per year industry. I told you bread was bad 26. February 2010 William Davis (10) "I dream about bread" 25. February 2010 William Davis (14) Marion sat in my office, sobbing. It had been 4 weeks since the last piece of bread, bagel, or bun had passed her lips. "I can't do it! I just can't do it! I've tried to eliminate wheat, but it's making me crazy. I'm having dreams about bread!"Yes, Timmy, such dark corners of human behavior are truly unveiled by removing wheat from the diet. (See the previous Heart Scan Blog post, Wheat withdrawal.)This is a real phenomenon: Wheat is the crack cocaine of the masses. Maybe you don't exchange $100 bills in dark corners of an inner city crack house, but I'll bet you paid $3.99 for your latest fix of French bread. Just in the last 2 weeks, people in my office who have eliminated wheat have experienced:14 lbs weight loss in 14 daysIncreased mental clarity, reduced moodiness, deeper sleep70% reductions in small LDL More than 300 mg/dl reductions in triglyceridesRelief from chronic scalp rashI could go on. All the while, the USDA, the American Heart Association, the American Diabetes Association, the American Dietetic Association, the Surgeon General's Office all advise you to eat more "healthy whole grains." 70% of people (NOT 100%, but the majority) will experience unexpected health benefits by eliminating this corrupt, unphysiologic product called wheat from their diet. You won't know until you try. Prototypical Lipoprotein(a) 25. February 2010 William Davis (23) Here's the prototypical male with lipoprotein(a):Several features stand out in the majority of men with lipoprotein(a), Lp(a):Slender--Sometimes absurdly so: BMIs of 21-23 are not uncommon. These are the people who claim they can't gain weight. Intelligent--Above average to way above average intelligence is the rule. Gravitate to technical work--Plenty of engineers, scientists, accountants, and other people who work with numbers and/or technical details are more likely to have Lp(a). Enjoy high levels of aerobic performance--I tell my Lp(a) patients that, if they want to see a bunch of other people with Lp(a), go to a marathon or triathlon. They'll see plenty of people with the pattern among the aerobically-elite. Are rabid fans of Star Trek. Okay, I made the last one up. But the rest are uncannilly true, shared by the majority (though not all) men with Lp(a). Why? I can only speculate that the gene(s) for Lp(a) are closely linked to gene(s) for intelligence of a quantitative kind and some factor that enhances aerobic performance or yields a desirable emotional state with exercise. Oddly, the same patterns tend not to occur in women in Lp(a). I have yet to discern a personality or body configuration phenotype among the ladies. Gastric emptying: When slower is better 20. February 2010 William Davis (18) When it comes to the Internet and Nascar, speed is good: The faster the better. But when it comes to gastric emptying (the rate at which food passes from the stomach and into the duodenum and small intestine), slower can be better. Slower transit time for foods passing through the stomach leads to lower blood sugar, lower blood glucose area under-the-curve (AUC), i.e., reduced blood glucose levels over time. Lower postprandial (after-eating) blood sugars can reduce cardiovascular risk. It can lead to a reduction in net calorie intake and weight loss. Strategies that can slow gastric emptying include:--Minimizing fluids during a meal--Drinking a lot of fluids, e.g., water, accelerates gastric emptying by approximately 20%. --Cinnamon--While the full reason to explain Cassia cinnamon's blood glucose-reducing effect has not been completely worked out, part of the effect is likely to due slowed gastric emptying. Thus, a 1/4-2 teaspoons of cinnamon per day can reduce postprandial blood sugar peaks by 10-25 mg/dl. --Vinegar--Two teaspoons of vinegar in its various forms slows gastric emptying. The effect is likely due to acetic acid, the compound shared by apple cider vinegar, white vinegar, red wine vinegar, Balsamic vinegar, and other varieties. --Increased fat content--Fat is digested more slowly and slows gastric emptying time, compared to the rapid transit of carbohydrates. Not everybody should slow gastric emptying. Diabetics with a condition called diabetic gastroparesis should not use these methods, as they can further slow the abnormal gastric emptying that develops as part of their disease, making a bad situation worse. However, in the rest of us with normal gastric emptying time, a delay in gastric emptying can reduce blood sugar and induce satiety, effects that can work in your favor in reducing cardiovascular risk. << Older posts Newer posts >> Newer posts12...252627282930313233...121122Older posts

Gastric emptying: When slower is better 20. February 2010 William Davis (18) When it comes to the Internet and Nascar, speed is good: The faster the better. But when it comes to gastric emptying (the rate at which food passes from the stomach and into the duodenum and small intestine), slower can be better. Slower transit time for foods passing through the stomach leads to lower blood sugar, lower blood glucose area under-the-curve (AUC), i.e., reduced blood glucose levels over time. Lower postprandial (after-eating) blood sugars can reduce cardiovascular risk. It can lead to a reduction in net calorie intake and weight loss. Strategies that can slow gastric emptying include:--Minimizing fluids during a meal--Drinking a lot of fluids, e.g., water, accelerates gastric emptying by approximately 20%. --Cinnamon--While the full reason to explain Cassia cinnamon's blood glucose-reducing effect has not been completely worked out, part of the effect is likely to due slowed gastric emptying. Thus, a 1/4-2 teaspoons of cinnamon per day can reduce postprandial blood sugar peaks by 10-25 mg/dl. --Vinegar--Two teaspoons of vinegar in its various forms slows gastric emptying. The effect is likely due to acetic acid, the compound shared by apple cider vinegar, white vinegar, red wine vinegar, Balsamic vinegar, and other varieties. --Increased fat content--Fat is digested more slowly and slows gastric emptying time, compared to the rapid transit of carbohydrates. Not everybody should slow gastric emptying. Diabetics with a condition called diabetic gastroparesis should not use these methods, as they can further slow the abnormal gastric emptying that develops as part of their disease, making a bad situation worse. However, in the rest of us with normal gastric emptying time, a delay in gastric emptying can reduce blood sugar and induce satiety, effects that can work in your favor in reducing cardiovascular risk.
