Is shock therapy the answer to “cure” obesity?

10. August 2014 Lisa G (0)

The next obesity “fix” may be hitting the market known as "VBLOC therapy”. This implanted device delivers intermittent electrical "blocking signals" to the intra-abdominal vagus nerve. According to the manufacturer, the device "reduces sensations of hunger and produces satiety leading to weight loss.”

Seems to me like another classic case of conventional healthcare proposing surgery or medications to address the obesity epidemic. Pharmacologic treatment and bariatric surgery have been offered for years to win the battle of the bulge. As a registered dietitian, who years ago begrudgingly counseled patients prior to undergoing bariatric surgery, I have seen countless people re-gaining all (if not more) of the weight lost after the first year of surgery. Same goes for pharmalogical interventions, such as Phentermine. Sure it worked in the short-term. But in every single case, when the medication was stopped, as it is not FDA approved for long-term use, the weight came creeping back.

My take on the releasing a significant amount of weight does not require going under the knife. How about this instead? Address the cause of increase hunger and appetite. This is a crucial missing link for many undergoing surgery or using medication(s) as a “solution”. Not addressing the cause of increased hunger and ravenous eating behaviors precipitously results in rebound weight gain. Rather than sending an electrical pulse to a nerve in the stomach, maybe the FDA should consider a Cureality-based nutrition program that is wildly successful stimulating a “side effect” of weight loss. Wheat elimination offers a surgery-free option that reduces hunger and insistent drive to eat every few hours, thanks to freedom from gliadin driven appetite stimulation. Weight loss is common experience due to reduced hunger and subsequent intake. Give it a try. What else do you have to lose, but some love handles?

Are Your Beauty Products Toxic?

10. August 2014 Lisa G (0)

As a nutritionist and self-care advocate, I am very careful about what I put in my body. Health benefits experienced through proper nutrition are well understood. We avoid highly processed foods, wheat-based products, and sugary snacks because we know that are “unhealthy” for us. But what about what we put on our skin?

An important piece of the health and wellness puzzle is not only what is on the end of our fork but on our toothbrush, slapped on our bodies and rubbed into our hair. Skin is the largest organ and what we place on it on a daily basis penetrates the skin, enters the fat stores and contributes to the toxicity and adiposity of our bodies. According to the Environmental Working Group, the average woman uses 12 beauty products per day, containing about 168 ingredients. Yikes!

I’ve often held a high suspicious that endocrine disruptors such as parabens, triclosan, fragrance, and other punitive chemicals are a key suspect in the root cause of my endocrine disruption. Interestingly, scientific evidence is now emerging to support this suspicion.

A few months back, I took a look at my hair, skin, and cosmetic products. I was shocked and horrified. Parabens, an estrogen-mimicking preservative linked with endocrine disruption, was in dozens of products. It reminded me of how I felt on that day years ago when I threw out all the products in my kitchen that contained wheat. What are parabens not in? Why was it in so many products?

In our next episode of Cureality Connections we will discuss key skin and beauty product chemicals to avoid along with other steps to take to attain beauty from within.

Top 3 Strength Training Exercises for Runners

28. July 2014 Amber B (0)

First and foremost, if you’re a runner and you’re not strength training you need to start. This in and of itself could be an entire blog article. But here I go with the synopsis.

Strength training will indirectly help you run longer and faster. Strength training exercises can improve your running mechanics, so that you run more efficiently. Efficient running mechanics will lead to less wasted energy with each step and less injuries.

Think about it. You will take 80 to 90 steps per foot each minute you run. If you have muscular imbalances that lead to joint mobility or stability issues you will move through an improper range of motion with each step.

When you run for 30 minutes you take 2700 steps with each foot for a combined 5400 steps. That could be 5400 steps of feet rolling in, rounded shoulders, wasted side to side movement or just pure pain. Needless to say, when you are an endurance athlete it’s important that each step and every workout is adding to improved performance not to injury or fatigue.

The key to becoming a better runner is consistency. For most runners, injuries are the biggest disrupter of consistent training. Runners get a few good weeks or months of training, and then they are injured. That means time off, loss of motivation, and a decrease in fitness.

Strength training with proper form 2 to 3 times a week will reduce the onset of injuries and improve your running form. Here are my top 3 strength training exercises for runners.

Bulgarian Split Squat

You will need a bench, chair or stepper to perform this exercise. Start by doing this exercise with just body weight and then progress. The progression could include holding dumbbells, kettlebells or a barbell. You can also make this exercise explosive.

Place the to top of your back foot on. If you are having a hard time with balance, flex your back toes and place them on the bench.
Stand in a staggered stance about 2 to 3 feet wide. This should allow your knee to bend while keeping your knees behind your front toes.
Inhale as you begin to bend both knees.
Focus on your back knee pointing straight down toward the ground and your body weight in your front heel.
Keep your front kneecap inline with the 3rd toe of the front foot.
Exhale as you straighten both knees to come back up to standing.

Start with 10 repetitions on each leg and progress to 15.

Calf Lowers

Use a stair or a stepper to perform this exercise. Start by doing this exercise with just body weight. The progression would include holding a dumbbell in one hand.

Place the ball of your foot on the stair while holding on to the wall or railing.
Rise up on the ball of your foot as high as your heel will go. Make sure you have weight evenly distributed on all of your toes and that you are not rolling onto one side of your foot.
Slowly, lower you heel back to the starting position. Try counting 3 to 5 slow counts to ensure you really focus on lowering part of the movement.

Do 10 reputations on each foot to start. Work up to doing 20 reputations on each foot.

Band or Cable Row

How many runners do you see hunched over logging long miles. This exercise is for improved running posture, which can lead to improved respiration.

To perform this exercise, use a band or a cable. This exercise can be done with both arms or with just one arm.

Stand in a staggered stance with relaxed knees. Make sure your ribs on stacked on top of your hips to ensure good posture.
Grab the handles of the band or the cable in the thumbs up position.
Start the movement by protracting the shoulder blades.
Then bend the elbows straight back so that your biceps are close to your rib care. Keep your knuckles forward.
To release, begin to straighten your elbows and bring your shoulders back to the starting position.

Start with 10 repitions and work up to 20. To increase difficulty, use a more difficult band or more weight on the cable system.

Here’s to improving your running mechanics so that you can train more consistently. Can’t wait to hear about the PR at your next race.

How did Cureality get its start?

27. July 2014 William Davis (0)

In the Cureality program, we embrace information and strategies that empower you in health without drugs, without hospitals, without procedures. We convert your doctor from director of healthcare to your assistant in health. He or she is there when you need help, but you largely direct your own health future.

How did we gain the know-how, information, tools, even chutzpah to take on such an ambitious project?

It started around 10 years ago with the awkwardly named Track Your Plaque program. In fact, some of the current followers of the Cureality program are former Track Your Plaque members, having learned of the wonderful list of strategies that can be adopted to gain better control over, even reverse, coronary atherosclerotic plaque and risk for heart attack. They also learned that something special happens when you engage with other people with similar interests, all sharing ideas, insights, and resources to get the self-directed health job done. Over time, what started out as simply a source of better information for coronary health evolved into a self-directed coronary disease management program. We never set out to create something as wildly ambitious as a do-it-yourself-at-home coronary disease risk management program, but that is how it inadvertently turned out.

How we went from Information Provider to Health Empowerment Program

So we never intended to take on something so seemingly impossible as managing coronary risk on your own. But, because we armed people with such empowering, profound insights into better ways to manage their heart disease risk beyond “don’t smoke, cut saturated fat, be active, and take a statin drug”—the typical advice offered by doctors—they returned after an interaction with their doctors disappointed: doctors often declared such strategies unnecessary, or the doctor didn’t understand them—even when there were clear-cut clinical data already available to support their use. In other words, the patients—everyday people, not experts—knew more than their doctors.

This flip-flop in the balance of knowledge made for some very interesting stories, like “Harold” (not his real name) who, having survived a heart attack and received a stent, was told by his doctor to cut his fat intake, eat more whole grains, exercise, take aspirin and a beta blocker drug, and reduce his cholesterol values with a statin drug. Upon learning all the additional information from the Track Your Plaque program, Harold returned to his doctor and asked “I’m not so ready to just go along with this idea of ‘reducing cholesterol’ to address heart disease risk. Because my goal is to gain as much control over coronary disease as possible, maybe even reverse it, I’d like to address some additional issues that I believe may be important. I’d like to have my advanced lipoproteins drawn to measure the proportion of small LDL particles I have, whether I have lipoprotein(a), an omega-3 fatty acid index and 25-hydroxy vitamin D level, and a thyroid assessment. Oh, and I believe I should also have an assessment of my inflammation status, perhaps a c-reactive protein and phospholipase A2, and my blood sugar status measured with a fasting glucose, insulin, and hemoglobin A1c.” Harold’s doctor was dumbfounded and speechless. Rather than reveal his ignorance, his doctor advised Harold that none of that was necessary, sending him on his way and telling him that he was fine.

But this left Harold with a sour taste in his mouth, having engaged in many online discussions with people who had followed conventional advice that resulted in more heart attack, more heart procedures—the conventional answers simply did not work. He also discussed his situation with people who had successfully obtained the additional information he sought, added it to their program and enjoyed dramatically improved health, including freedom from more heart attacks, heart symptoms, and heart procedures, as well as improved overall health. So Harold found an easy way to obtain the testing on his own. Within a couple of weeks, he returned to his online community and shared all his information. Within moments, he was provided useful discussion to help him understand the values, all leading to changes in nutrition, nutritional supplement choices, how and where to get the simple tools necessary, such as iodine and vitamin D supplements. He even entered his data, choosing which values he was willing to share with others, which remained private, allowing him to compare his own follow-up values several months later. Engaged in this process, self-directed but collaborative, he witnessed marked transformations in his health. Not only did he never again—over several years—ever re-develop heart symptoms nor require any more trips back to the cath lab, he lost weight, reversed a pre-diabetic sugar profile, improved his cholesterol values without drugs, got rid of the acid reflux symptoms he endured for many years, dropped his blood pressure to normal, enjoyed better mood, energy, and sleep. Slender, healthier, all accomplished without his doctor.

Harold returned to his doctor for a routine follow-up. Slender, energetic, without complaints, on no drugs except the aspirin for his stent, the basic laboratory assessment his doctor ordered in front of him, his doctor admitted,” Well, I don’t know how you’re doing it, but these values look like a 20-year old substituted his blood for yours. They’re unbelievable. What drugs are you taking to do this?” “No drugs,” Harold replied, “I’m following a program to reverse heart disease, but it means doing some things that are different from conventional solutions.” His doctor closed their meeting with the signature response of doctors nationwide: “Well, I don’t understand what you are doing, but just keep doing it.”

Yes, Harold knew more about how to control heart disease than his doctor, more than his cardiologist. The cardiologist knew how to insert a stent or defibrillator. But deliver information that empowered Harold in all aspects of health from head to toe, while also dramatically reducing, perhaps eliminating, his coronary disease risk? As you now know, that is not what conventional healthcare does, nor is it interested in doing so, as it would relinquish control and threaten to cut off this hugely profitable revenue stream that drives “healthcare.”

Having managed to inadvertently create a self-directed coronary risk management program with such spectacular results and in probably one of the most difficult areas of all—heart disease—it became clear that a similar approach could be even more easily applied to many other areas of health, such as weight loss, bone health, cholesterol and blood pressure issues, diabetes and pre-diabetes, hormonal health, autoimmune conditions, and others. You can do it when empowered by safe, effective information, and supported by a community of sharing and collaboration. We don’t fire our doctors; they are there when we need them when, for instance, we get injured or catch pneumonia, or as an occasional resource. But doctors should no longer be able to get away with neglect, misinformation, or blindly directing you to the next revenue-generating procedure because you are empowered by the information and support you receive in Cureality.

As we get more effective in delivering this information and new tools to you, just imagine what we can accomplish in this new age of information and self-empowerment. The future for us is bright with ambitions for better interactive tools with Cureality expert staff, better ways to crowd source health answers, provide more engaging community conversation, all while the health insights that help accomplish our self-directed health goals get better and better. Each person that joins Cureality helps make this service more effective because your wisdom, insights, and experience are added to the collective knowledge. We are more powerful together than we are as individuals.

If you are already a Cureality Member, please add your comments and questions to the growing conversation. If you are not a Member, consider joining our discussions, as each new voice gets us closer and closer to better answers to take back control over health.

Sit Less and Move More.

21. July 2014 Amber B (0)

We sit way too much. Many of us have desk jobs where we sit for 8 to 9 hours a day. After we leave the office, we sit in our car to run errands. We follow that by sitting down to eat dinner. Our day ends by sitting on the couch to unwind by watching some television.

Many of us will be sitting a good 12 to 15 hours each and every day. Unfortunately the research shows that long hours of sitting can lead to obesity, heart disease, diabetes, and even early death. Don’t be fooled that your workout is enough movement. You can still be active and sedentary.

How can you add more movement to your day? First, think about all the times you find yourself sitting during the day. Then come up with a creative way that you can get out of the seat and move your feet.

Here are a couple of examples:

Instead of driving everywhere, jump on your bike. The picture above is of the bike I use to go to work or run errands. Bike riding is great exercise, greener transportation and a great stress relief.

We spend a lot of time at work sitting in front of the computer or the phone. Prop your laptop on a bookshelf to create a standing workstation. You can also purchase a sit-stand workstation you can adjust throughout the day. Get a headset and stand during phone calls.

Walk during your lunch break. Walk to the coffee shop, the mailbox, and the dry cleaners. Get your errands done on foot or just enjoy a stroll outside.

Take a movement break every hour. Do some desk push-ups, squats or walk the stairs. Need to communicate with a coworker? Don't email, walk over and talk to them.

Human beings are meant to move, not sit in chairs all day. I want to challenge you to incorporate more movement into your day. I'd love to read your comments how you move more and sit less.

Have You Had Your Prebiotics Today?

11. July 2014 Lisa G (0)

Prebiotics and resistant starch may be the missing link to your digestive health. Indigestible fibers that allow healthy bowel flora to proliferate and thrive are often called prebiotics. They are also known as resistant starches, because they are resistant to human digestion. I recently had a client call the addition of resistance starch to her diet, “the missing link my body needed”.

A starch that resists digestion and reaches the large intestine becomes food for the healthy bacteria in the large intestine. These bacteria can break down and “feed on” the resistant starch thus providing the friendly bacteria with the fuel they need to survive.

Imbalance of the quantity and type of bacteria species present in the gut contributes to gastrointestinal illness, blood sugar imbalance, obesity, mood disorders, and immune system challenges.

Green unripe bananas and plantains are one of best sources for prebiotic fiber content with 27 to 30 grams of fiber in one medium banana. Green bananas are essentially inedible. They are most easily incorporated into diet by blending into a smoothie.

One mistake frequently made incorporating prebiotic fibers from bananas is consuming bananas that are too ripe. Once the banana ripens the resistant starch is degraded and become a digestible starch. Thus, no longer a good prebiotic fiber source. In fact, the riper the banana becomes the higher the glycemic (blood sugar) response.

It can be difficult to find bananas that are very green. I made several trips to my local grocery store to find these bowel flora champions. I find it helpful to ask the produce clerk to take a look at the shipment that just arrived, noting the day the shipment arrives, for the best chance to gobble up these green beauties.

In an effort to keep green bananas green I tried a few strategies. One that sounded promising was wrapping the end of the banana to prevent the ethylene gas, which ripens the fruit, from dissipating. You can see from the image this clearly did not work. After a mere two days the green bananas were no longer green. What I found works best is placing the green bananas in the fridge. This halts the ripening process. The skin of the banana will turn brown, which is normal, but the fruit inside is still good. I’ve kept bananas in my fridge for up to 8 days and they hold up well other than the brownish black discoloring that develops on the skin. The banana will be firm and require a knife to cut the skin off the banana.

If you’d like to learn more about prebiotics and strategies to support resolution of common gastrointestinal complaints read the recently release Cureality Guide to Healthy Bowel Flora by Dr. Davis. This guide is one of the many valuable resources available exclusively to Cureality.com members.

Something is Better Than Nothing

2. July 2014 Amber B (0)

This past weekend I attended a fitness conference with an amazing lineup of presenters. Even after 11 years in the fitness industry, I love attending these events. I’m a lifetime student always learning more and honing my craft.

I went to a presentation by Al Vermeil about joint mobility, not knowing anything about him. To my surprise, Al was the strength and conditioning coach for the Chicago Bulls and the San Francisco 49ers the years these teams won championships in their respective sports. That’s a pretty impressive resume.

Al was a great presenter, full of fun and practical advice. During his presentation, Al said the following statement:

“Every time you miss a workout, the next one is easier to miss.”

This statement really hit home because I’ve seen this time and time again working in the fitness industry and in my own life. One workout is missed, then an entire week of workouts are missed, then it’s been an entire month of never setting foot back into the gym.

It’s easy to get thrown off your workout routine when life gets busy and days get long. So what do you do? Do you just trash your workout plan?

The all or nothing attitude is common when it comes to making health changes. Either you’re following your plan 100% or you not. I’m here to tell you that doing something is better than nothing. Doing part of your workout or a mini workout is better than missing an entire workout.

The other day I had the choice to do something or nothing. I had a full day of work meetings, video, and family commitments. Here is what happened. I did shorter variation of my joint mobility routine. I followed that with a quick kettlebell circuit of 25 kettlebell swings, 12 kettlebell overhead presses, and 12 kettlebell goblet squats. I did three rounds of this circuit. That’s it! The following day, I got back to my regular exercise routine.

Be consistent with movement and you’ll always see improvements. That’s the magic of exercise. You'll get better if you just do it.

What’s the Problem with My “Healthy” Bowl of Oatmeal?

26. June 2014 Lisa G Nutrition, Oatmeal (0)

Food manufacturers have clever ways to market foods to us. Unfortunately, many foods that have a reputation for being healthy are no more than junk food disguised as a healthy food choice. I commonly see people under the influence of a “health halo” effect. This is due to strategic marketing efforts. People overestimate the nutritional value of a food that is labeled “good for you” or they underestimate the negative impact of a food because it contains a healthful ingredient, like flaxseed or fiber. In fact, a recent study from the University of Houston found that terms on food labels such as antioxidants, all-natural, and gluten-free often are used to give an otherwise standard food a "healthy" halo, and influence consumption from the well- intended consumer.

Case in point-- oatmeal. We’ve all heard about the cholesterol lower benefits from soluble fiber contained in oatmeal. It’s blasted all over packages with a paid endorsement from The American Heart Association. However, that’s not the whole story. Most people enjoy a cup of oatmeal with one to two tablespoons of added sugar and fruit such as a ripe, yellow banana. In other words, let’s enjoy a bowl of “send my blood sugar through the roof” high glycemic oatmeal. The glycemic index of oatmeal is 55, and instant oatmeal is 83. Top that with more table sugar, glycemic index 58-65 and better yet top that with a high glycemic, ripe banana with a GI of 62.

Preparing one packet of regular instant oatmeal with one tablespoon of sugar and a medium ripe banana five days per week would result in the sugar equivalent of more than 5 1/2 cups of sugar per month!

Furthermore, the story many Americans are missing is all of that sugar intake, from their so-called “healthy” bowl of oatmeal, actually raises small-dense LDL cholesterol particles, increases blood sugar and contributes to insulin resistance, faulty gut flora, and belly fat.

How do we improve upon our bowl of oatmeal? Enjoy a bowl of hot coconut flaxseed cereal, eggs any variety of ways, or last night’s leftover salmon and vegetables.

The Cureality program provides tools, guidance, and support that does not follow the party line but rather offers nutrition solutions that address the underlying causes for proliferation of many chronic diseases.

Power in Numbers

25. June 2014 William Davis (0)

In his book, The Wisdom of Crowds, author James Surowiecki begins with the story of an ox judging competition in which 800 people—not ox experts nor breeders, just ordinary people attending a county fair—were asked to guess the weight of the ox. The competition was conducted by a scientist, Francis Galton, who held a low opinion of the intelligence of the average person, remarking that “the stupidity and wrong-headedness of many men and women being so great as to be scarcely credible.” He hoped to prove, by examining the various guesses, that the average person had no idea of how to judge the real answer. After all participants casted their written votes, Galton tallied up the total and averaged the result: 1,197 pounds—just one pound off from the real weight of 1,198 pounds. Few individuals actually guessed the correct weight themselves but, when the opinions of many were combined, the result was near-perfect.

Crowds can also be a source of irrational behavior, panic, and stampede. Witness any modern football or soccer game, for instance, in which fights break out over an issue as minor as a disputed call or a heckle. Or go back through history to the countless events when mass hysteria ruled, such as the Salem Witch Trials or Orson Welles’ War of the Worlds radio broadcast.

Let’s put aside examples of mass emotional chaos of the sort that causes crowds to stampede store doors on Black Friday. Let’s focus instead on conscious, considered, thoughtful opinions. We all accept that there are as many opinions on issues as there are people, not uncommonly with widely divergent views. But can we, as Galton’s famous experiment did, combine the opinions of many and come away with some fruitful insight—the correct answer? Just as the people participating in Galton’s experiment were not experts, so Cureality participants—a crowd-sourced collection of opinions—are not experts. If we were to poll everyone to identify their area of expertise or experience, it would likely include finance, the retail industry, raising children, or teaching—but not health. Yes, we have experts curating the direction of content, but we also crowd-source collective opinion.

Right now, Cureality is based on existing science, the philosophy of self-directed health, combined with guidance and community to help the participant along in the sometimes complex world of health questions. But as our processes and procedures improve, can we—like Galton’s ox weight guessers—come away with coalescent wisdom, answers to our health questions, near-perfect solutions to health conditions that have eluded the “experts” for centuries?

I think that we can. No, I know that we can. We enter a new age in information and harness the power of the crowd-sourcing of solutions, even when no single individual has the complete answer herself.

Use This Trick to Boost Exercise Motivation

23. June 2014 Amber B (0)

Are you been struggling to get your workouts in?

Do you belong to a gym and find that you're not going?

Do you have exercise equipment sitting in your basement collecting dust because you find that you just can’t get yourself down there?

If you answered, “yes” to any of these questions you are not alone. Many people struggle with finding the motivation to exercise.

The problem here is that you have head trash going on. Head trash is that voice inside your head coming up with a million excuses that inhibit you from carving out a bit of time to take care of yourself.

Head trash will tell you that you’re too tired, even though a workout would give you a boost of energy.

Head trash will tell you that you’re too busy, even though you just spent a half hour on Facebook.

Head trash is barking at you to take care of others, even thought you know your health is important for you well being.

Head trash is a real conflict that can get in the way of our health and fitness goals. We start an exercise program with the intentions of a long-term commitment. But after the initial excitement wears off, we find our workouts occurring less frequently. Head trash begins to take over and soon we find ourselves not exercising at all.

Here is my secret for winning the battle over the head trash that keeps getting in way of your workouts. Tell yourself that you are only going to exercise for 10 minutes and evaluate if you want to continue. If you're truly too tired you can stop after 10 minutes. If you're truly too busy you can stop and move onto a task that needs your attention.

Making this deal with your mind that you are only going to exercise for 10 minutes seems reasonable. The head trash will become quite because your mind is convinced it has an out within 10 minutes.

I've used this 10-minute trick myself. I grind through the first few minutes, but then the magic happens. Once you hit the 10-minute mark your body takes over. Exercise feels amazing and your body is energized and enjoying the movement. You have tricked your mind to get over the hurdle of starting and now you’re in the exercise groove.

Try the 10-minute trick next time your head trash is getting in the way of your workout. You'll be amazed how your workout consistency improves.

What's that in your mouth?

7. January 2010 William Davis (17)

Fat = triglycerides

In other words, eat fat, whether it's saturated, hydrogenated, polyunsaturated, or monounsaturated, and blood levels of triglycerides will go up over the next 6 hours. This remains true if there are carbohydrates in the meal, or if there are NO carbohydrates in the meal. It also remains true if you chronically consume fats.

While fats are the primary determinant of postprandial (after-eating) triglycerides, carbohydrates are the primary determinant of fasting triglycerides.

So, if your triglycerides are high on a fasting cholesterol (lipid) panel, it's most likely because you overconsume carbohydrates.

De Novo Lipo-what?

5. January 2010 William Davis (16)

Humans have limited capacity to store carbohydrates. Beyond the glucose and glycogen in our blood and tissues, we have relatively little carbohydrate to draw from in time of energy need. That's why long-distance runners and triathletes have to carry sugar sources to keep blood sugar from plummeting.

Fat, of course, is different. We have virtually unlimited capacity to store energy as fat.

Because we have limited carbohydrate storage capacity, what can the body do with the excessive quantities of carbohydrates that Americans ingest? What becomes of a bagel for breakfast, wheat crackers for snacks, a whole wheat sandwich for lunch, pretzels, and whole wheat pasta that many people eat every day, not to mention the chips, soft drinks, and juices?

Excess carbohydrates are diverted to an interesting metabolic pathway called de novo lipogenesis (DNL). This refers to the liver's ability to make triglycerides from excessive carbohydrates in the diet. Triglycerides are packaged for release into the blood as VLDL. VLDL, in turn, interacts with other lipoproteins, creating small LDL particles, reduced HDL and smaller, less protective HDL. High VLDL will be measured on a standard cholesterol panel as higher triglycerides.

A University of California (Berkeley, San Francisco) group has done much of the work describing DNL.

A diet weighed towards carbohydrates, especially if 50% or greater calories are carbohydrate, is sufficient to provoke plenty of DNL, even in slender people. DNL is a big part of the reason why low-fat (and, thereby, high-carbohydrate) diets result in higher triglycerides. DNL really gets turned on many-fold if the carbohydrates are "simple," rather than "complex."

Overweight people, however, can demonstrate five-fold greater DNL even with lesser quantities of carbohydrate intake (e.g., 40% fat, 46% carbohydrate, 14% protein):

From Schwarz et al 2003. Mean (± SEM) fractional de novo lipogenesis in lean normoinsulinemic (NI), obese NI, and obese hyperinsulinemic (HI) subjects after 5 d of consuming a high-fat, low-carbohydrate diet and in different lean NI and obese HI subjects after 5 d of consuming a low-fat, high-carbohydrate diet. Values with different superscript letters are significantly different.

Excessive carbohydrates, a la standard low-fat diets, are good for nobody. The concept of de novo lipogenesis fills in a theoretical hole that now explains why people who eat carbohydrates have higher triglycerides, VLDL, and, eventually, insulin resistance and diabetes.

Gretchen's postprandial diet experiment II

3. January 2010 William Davis (37)

I previously posted Gretchen's postprandial diet experiment, in which she consumed a low-fat diet for a day, followed by a low-carbohydrate diet for a day. Grethen monitored blood glucose and triglycerides with fingerstick checks. (Blood glucose can be checked on any widely available glucose monitor; triglycerides can be monitored with the Cardiochek device.)

Let's now discuss what happened.

On the low-carb, high-fat day, there was an initial surge in triglycerides to 250 mg/dl late morning, followed by a secondary peak several hours following dinner. Because fat is mostly triglycerides, Gretchen's high-fat (sausage, bacon, butter, whole-fat yogurt) breakfast provided a large quantity of triglycerides that needed to be absorbed. This generally occurs over approximately 6 hours, varying depending on body weight, how accustomed you are to fat, activity level during the day, the kind of fat in the meal. The high content of saturated fat in Gretchen's high-fat breakfast likely caused the somewhat slower drop in triglycerides over approximately 7 1/2 hours.

As Gretchen herself had noted, triglycerides the following day were lower, a typical low-carb response. Blood sugar throughout showed only minor variation, with only small postprandial increases.

Thus, Gretchen experienced what we'd expect with a low-carb, high-fat diet: an initial high surge in triglycerides, followed by a decline in fasting levels, while blood sugar shows a normal contour.

Now, the more confusing low-fat experience:

Blood glucose makes a striking peak at 200 mg/dl after the low-fat breakfast of pasta and rice, in contrast to the low-carb breakfast. Triglycerides behaved very differently from the low-carb experiment: While there was no initial postprandial surge, there was a late surge developing 6-24 hours later. The late surge continued into the next day, with fasting levels the following morning (210 mg/dl) exceeding the starting triglyceride level (60 mg/dl).

The one potentially confusing aspect of all this is Gretchen's late rise in triglycerides on the low-fat diet. This phenomenon is due to something called de novo lipogenesis, or the liver's conversion of carbohydrates to triglycerides that occurs when an excessive carbohydrate load comes through diet. Because the human body cannot store anything beyond a minor quantity of carbohydrates (as glucose and glycogen), carbohydrates are converted to fats.

Another factor causing the late triglyceride increase is insulin resistance, given the high blood sugar response. When insulin resistance is present, the activity of the enzyme, lipoprotein lipase, is reduced. Less lipoprotein lipase activity allows slower VLDL degradation, allowing VLDL (and thereby triglycerides contained in VLDL) to "stack up" in the blood. Thus, the higher triglycerides late after eating and into the next morning.

One issue to be aware of: Acute responses can differ from chronic responses. In other words, had Gretchen had the luxury (and time and money) to conduct the experiment over, say, 4 weeks, rather than a single day, there would be somewhat different responses. The best data on this come from Dr. Jeff Volek of the University of Connecticut, in which 4 weeks of low-carbohydrate eating modify fasting and postprandial responses over time.

Several conclusions can be made from Gretchen's experience:

1) Low-carb, high-fat acutely generates extravagant postprandial triglyceride responses.
2) Low-fat causes a late triglyceride surge and higher fasting triglycerides.
3) Low-fat leads to high blood sugars and, by implication, diabetes.

Both the low-carb and the low-fat responses are undesirable, both leading to increased risk for heart disease. Which is worse? I believe that low-fat is more destructive, since it leads over time to both high triglycerides and diabetes, while low-carb/high-fat only leads to postprandial triglyceride surges, at least acutely.

How to best balance the responses to reduce risk for heart disease? That's a discussion for future.

Again, my thanks to Gretchen and the substantial amount of effort that went into generating these numbers. More of Gretchens' own writing can be found on her blogs:

A wheat-free 2010

2. January 2010 William Davis (22)

A Heart Scan Blog reader sent this fascinating description of his wheat-free adventure.

Whenever I discuss this notion of going wheat-free and the incredible health effects that develop, I invariably receive comments or emails saying something like "I eat wheat and feel fine. That can't be true." The problem is that not everybody needs to go wheat-free. 20-30% of people can include wheat in their diet and suffer little more than weight gain, some not at all.

But stories like Michael's (below) are commonplace in my experience. I've had many patients who, at first, refused to believe that wheat exposure might be the underlying cause for health struggles. But they finally give it a try and find that rashes, arthritis, acid reflux, irritable bowel symptoms, mood swings, anger, etc. are miraculously improved or gone.

Anyway, hear what Michael has to tell us:

Dr. Davis,

I want to thank you. I was browsing the web a while back and happened to stumble upon your blog post about wheat belly. The first thing that caught my attention was that I thought you had somehow gotten a photograph of me. The young man you posted an image of looked exactly like me. So I read what you had to say. After reading, I thought "Four weeks isn’t so bad. I think I can handle this."

It has now been nine weeks and all I can say is that I am completely amazed. Let me say first that twice in the past twenty years I have been tested for allergies. The first time I was tested I showed a slight reaction to Timothy Grass, but not enough to cause me any problems. The second testing I did not show a reaction to anything. So, I have always assumed that my chronic sinus problem were due to sensitivities to environmental pollutions. Now I am not so sure. I would like to list for you everything that has happened to me since I eliminated wheat from my diet.

1. I have lost a total of 12 pounds in the last 9 weeks.
2. I have lost 1 ¼ inches of belly fat
3. I have lost a tremendous amount of fat from my neck.
4. My entire life I have had problems with oily hair. I could wash my hair and three hours later I looked as if I hadn’t washed in a week. Now my hair stays clean and soft for two to three days without shampoo.
5. My hair was always flat and stringy. Now it has lots of body.
6. I used to have thick layers of dry skin on my scalp. It would come loose in chunks as large as a fingernail. That dry scalp is gone.
7. I used to have dry flaky skin that seemed to secrete oil. That no longer happens. My skin is now soft and smooth.
8. I have lived with bad acne for at least 35 years. Now it is hard to find a pimple on my body.
9. I have always had to fight dehydration. That is no longer a problem.
10. I used to drink two large cups of coffee every morning just to be able to function. I now have enough energy that I have eliminated caffeine from my diet.
11. I sleep more soundly than ever before and my dreams are clear and vivid.
12. My thought processes are more active and clear than they have ever been.
13. My chronic sinus issue is now a thing of the past.
14. I used to have problems with getting the “shakes” if I had gone more than a couple of hours without eating. It was as if I was suffering from low blood sugar. I would even be afraid that I would pass out. Now all I feel is hunger. I can go all day without eating and never feel in danger of losing consciousness.

Today is Thursday. This past Monday my wife and I were eating out and I ordered a burger without a bun. What I didn’t realize was that the burger would arrive covered in onion rings. I knocked the mountain of onion rings onto the plate but there were still a couple that were embedded in the cheese. I decided, what the hell, a couple of onion rings shouldn’t make that much of a difference. I will not make that mistake again anytime soon. Within 30 minutes I felt like there was a steel spike going through my left eye socket. I don’t remember ever being in that much pain. My sinuses were exploding. This morning, as I write this, I still feel the vestiges of that pain. Just enough that I know it is there. But after two and a half days, I am at least able to function again.

I owe you a debt of gratitude. You may have just saved my life. In the very least you have given me the means to improve my life in ways that I never thought possible.

Thank you so much,
Michael B.

Now, if wheat exposure can do that in Michael, what damage can it do in other people?

Personally, I previously experienced many of the same symptoms that Michael suffered, all gone with wheat elimination.

My advice: If you have any inkling that you might have a wheat sensitivity, make a New Year's resolution to stay wheat-free for 4 weeks and see whether you can feel any difference. Not everybody will, but many will be telling us about the dramatic health turnarounds they experienced.

Lipoprotein lipase and you

30. December 2009 William Davis (0)

Lipoprotein lipase can make the difference between having heart disease and not having it. Having sky-high triglycerides or normal triglycerides. It can mean dinner hanging around for over 12 hours in the bloodstream, rather than the usual 4-6 hours.

If you take niacin, you must exercise

30. December 2009 William Davis (23)

We use a lot of niacin in the Track Your Plaque program.

Niacin:

--Increases HDL and shifts HDL towards the large, protective fraction

--Reduces small LDL--In fact, niacin is the best treatment we have to reduce small LDL after wheat elimination and carbohydrate reduction.

--Reduces fasting and postprandial (after-eating) triglycerides

--Reduces heart attack risk by 20-28%--even as a sole agent.

But . . . niacin also triggers higher blood sugar because it partially blocks the effects of insulin (insulin "resistance").

While the net effect of niacin remains positive, the provocation of insulin resistance is not such a good thing. Can it be minimized or eliminated?

Yes, through exercise. Here's one interesting observation in obese (BMI 34.0), sedentary men given placebo, exercise, niacin (1500 mg Niaspan, once per day), or niacin + exercise:

From Plaisance et al 2008.

Blood was drawn following a high-fat meal challenge. (Yes, a high-fat challenge, not a carbohydrate challenge. In this study, there were only 17 grams carbohydrates in the test meal, but 100 grams fat. More on this in future.) Exercise consisted of walking for 50 minutes at a moderate pace one hour prior to the meal challenge.

You can see from the graph that exercise partially corrected the increased insulin level provoked by niacin.

Judging from this and other studies, exercise can help minimize the insulin-blocking effects of niacin. It doesn't take much, just moderate exercise for at least 30 minutes.

Adequate sleep can also help, since sleep deprivation is a potent trigger for insulin resistance, only worsened in the presence of niacin. Vitamin D supplementation to achieve desirable blood levels (which I define as 60-70 ng/ml) is also an effective means to minimize this effect.

To track small LDL, track blood sugar

24. December 2009 William Davis (28)

Here's a trick I learned after years of fussing over people's small LDL.

To gain better control over small LDL, follow blood sugars (blood glucose).

When you think about it, all the foods that trigger increases in blood sugar also trigger small LDL. Carbohydrates, in general, are the most potent triggers of small LDL. The most offensive among the carbohydrates: foods made with wheat. After wheat, there's foods made with cornstarch, sucrose (table sugar), and the broad categories of "other" carbohydrates, such as oats, barley, quinoa, sorghum, bulghur, etc.

Assessing small LDL requires a full lipoprotein assessment in which small LDL particles are measured (NMR, VAP, GGE). Not the easiest thing to do in the comfort of your kitchen.

However, you can easily and now cheaply check your blood sugar. Because blood sugar parallels small LDL, checking blood sugar can provide insight into how you respond to various foods and know whether glucose/small LDL have been triggered.

Here's how I suggest patients to do it:

1) Purchase an inexpensive blood glucose monitor at a discounter like Walmart or Walgreen's. You can buy them now for about $10. They're even sometimes free with promotional offers. You will also need to purchase lancets and test strips.

2) With a meal in question, check a blood sugar just prior to the meal, then again 60 minutes after finishing the meal. Say, for example, your pre-meal blood sugar is 102 mg/dl. You eat your meal, check it 60 minutes after finishing. Ideally, the postprandial (after-meal) blood sugar is no more than 102 mg/dl, i.e., no higher than pre-meal.

Perhaps you're skeptical that oatmeal in skim milk with walnuts and raisins will do any damage. So you perform this routine with your breakfast. Blood sugar beforehand: 100 mg/dl. Blood sugar 1 hour post: 163 mg/dl--Uh oh, not good for you. And small LDL will be triggered.

This approach is not perfect. It will not, for example, identify "stealth" triggers of blood sugar and small LDL like pasta, for the same reasons that pasta has a misleadingly low glycemic index: sugars are released slowly and not fully evident with the one-hour blood sugar.

Nonetheless, for most foods and meals, tracking your one-hour postprandial blood sugar can provide important insight into your individual susceptibility to sugar and small LDL-triggering effects.

C-reactive protein: Fiction from the drug industry?

21. December 2009 William Davis (0)

C-reactive protein (CRP) is the liver product of inflammatory responses anywhere in the body. If there's an inflamed left knee, CRP will be increased. If viral bronchitis is making you cough, then CRP will be increased.

The argument put forward by the drug industry is that, because CRP indicates underlying inflammation, very low-grade levels that can be measured in the absence of overt inflammation like the sore knee or bronchitis is associated with increased risk for cardiovascular events. There are now many studies that conclusively demonstrate that, the higher the CRP, the greater the cardiovascular risk.

Naturally, any marker of risk is followed by the inevitable study: Do statin drugs reduce the excess cardiovascular risk of excessive CRP?

And, yes, indeed they do. My statin-crazed colleagues rave about the so-called "pleiotropic," or non-lipid, effects of statins. CRP reduction and the reduction of risk associated with CRP result with statin treatment.

But is life really statin vs. placebo, as most statin trials are constructed? Are there strategies that can outdo statins like Crestor for reduction of CRP?

Watch your fish oil labels

17. December 2009 William Davis (36)

A quick quiz:

How much omega-3 fatty acids, EPA + DHA, are in each capsule of fish oil with the composition shown on the label below:

If you said 1340 mg (894 mg + 446 mg), sorry, but you're wrong. There are 670 mg EPA + DHA per capsule.

Did you notice that the composition, or "Supplement Facts," lists the contents of two capsules? Rather than the usual one capsule contents, this product label lists two capsules.

I don't know why some manufacturers or distributors do this. However, I have seen many people tripped up by this kind of labeling, taking half the omega-3 fatty acids they thought they were taking. This can be important when you are trying to obtain a specific dose of EPA + DHA to reduce triglycerides, reduce Lp(a), control abnormal heart rhythms, reduce bipolar mood swings, or other important effects.

I liken this to pulling up to a gas station where the sign says gasoline for $1.25. Wow! Can't beat that! You then find out that it's really $1.25 for a half-gallon, or $2.50 a gallon.

In truth, the labeling is accurate; it's just very easy to not notice the two capsule composition.

Why do I need a prescription for Olava?

16. December 2009 William Davis (0)

Imagine this:

What is OLAVA?

Olava is prescription olive oil. It is the purest, highest concentration of olive oil available.

Why Do I Need a Prescription for OLAVA?

Studies show that olive oil contains essential fatty acids, "good" fats that:

--Contain natural compounds your body needs for good health but can't produce on its own.

--Has antioxidants that may provide protection from heart disease.

So, it is common for people to ask why they need a prescription for OLAVA if it is made from a natural ingredient--olive oil. It's time to get the facts about OLAVA. Learn why OLAVA is different from olive oil you can buy at a store.

OLAVA Is an FDA-Approved Medication

OLAVA is the only FDA-approved medicine made from olive oil that's proven, along with diet, to reduce risk for heart disease

The FDA enforces standards to make sure that prescription medications like OLAVA are safe, effective, and quality controlled.

The way OLAVA is manufactured is reviewed and approved by the FDA.

OLAVA uses a 10-step purification process that helps remove lead and other environmental toxins that can be present in olive oil.

Each 1-gram capsule of OLAVA contains 1000 mg of pure olive oil.

The FDA-approved dose of OLAVA is 4 capsules per day. It could take up to 2 tablespoons per day of regular olive oil to provide the same amount of active ingredients proven to lower heart disease risk.

What Else You Should Know About Olive Oil

Regular olive oil has not been approved by the FDA to treat any specific disease like heart disease.

Olive oil doesn't have specific dosing information; it has a food label.

Olive oil does not go through an FDA-approved manufacturing process.

Talk to Your Doctor About OLAVA

If you have very heart disease, you may need a prescription medicine, along with diet, to treat your condition. Talk to your doctor about OLAVA. Print a trial offer to use on your first prescription of OLAVA.
