    I assume you don't agree that the cholesterol hypothesis is "wrong," since you recommend reducing LDL to 60.

    Fat Head has been in the back of my mind for awhile, but you've reminded to to go ahead and order it.  I think it will be great to pass on to friends curious about paleo/low-carb without having their eyes glaze over.  Very jealous of the cruise -- gotta get on it next year.

    Most of the people in extreme high carb cultures are Asians before their food started getting westernized.  And they had very low rates of heart disease, diabetes, and obesity  It's a population of billions, not a study of small group.  

    If carbs are bad for me(and I am more and more thinking they are bad for me) why weren't they bad for them?

    I'm not arguing for any particular diet, I'm trying to figure out what to have for dinner.

    Most folks who bash Ancel Keys haven't actually opened any of his books.  They would be surprised to discover he advocated eating organ meats, wild fish and game, and real food.  One of his books has a chapter on choosing the proper wines for dinner.  He was a fan of espresso coffee about 30 years before we all started going to Starbucks.  His dietary advice was not ultra "low-fat" a la Ornish.  In fact, he mainly recommended substituting unsaturated fats for saturated, which is advice you hear from many contemporary sources, including the first "Paleo" proponents like Lorne Cordain.  It's advice that has appeared from time to time on this very blog!

    Keys undoubtedly got a few things wrong.  All scientists and researchers do.  Their mistakes are corrected by those who follow.  That's the way science works.  To blame him for the obesity crisis, or for the "low-fat" marketing strategy that Food Inc concocted in the 80s and 90s, is silly.  As for the lipid theory itself, the naysayers have their own sorting out to do. Some say it's all bunk, others want to keep bits and pieces of it.   When the science behind one of these camps becomes overwhelming, their view will prevail. This takes a while.  Nutrition is an extremely complex subject!

    As for Keys, he lived to be 100 following the Mediterranean diet he advocated for others.  His wife and co-researcher Margaret died at 97. Call that anecdotal evidence if you want.  I call it having the last laugh your critics.

    I like this trend of documentaries making it to the cinema, beats the butchered remakes of classic films, and the pomp of it attracts a wider audience.
    Michael Moore seems to have started kick-started it all.

    Hi, Steve--

    Not knowing what to expect when Jimmy Moore invited me to join his cruise, I didn't tell everyone about it.

    However, now having had the experience, I can recommend it wholeheartedly to anyone desiring a fun informative experience for the low-carbohydrate eating viewpoint. Jimmy seems to have a talent for appealing to speakers who come from a diverse panel of perspectives, all who contribute something unique to the low-carb conversation.

    I lived more than a decade in Korea and China and made several visits to Japan and Southeast Asia.  The only high-carb food on the table is a bowl of rice or noodles.  The other dishes contain non-starch veggies, legumes, and some animal protein.  The liquid on the table is water or unsweetened tea.  Traditionally Asians don't snack between meals and rarely eat sweets although young people are picking up these habits and it shows.  Fruit is expensive, consumed only in season.  The SAD probably contains more easily digested carbs than traditional Asian diets.  

    True obesity is rare, but type II diabetes is not, and neither are cardiovascular diseases.  Americans are much more likely to get heart attacks while Asians are more likely to have strokes.

    Peter,

    You'd have to travel to Asian countries to fully understand what their diet is all about. It's not what you think. The BIGGEST problem is that we eat way too much of carbs.

    I just saw documentaries of North Korea and pretty much every single person is skinny. Only the "president" of NK looked to be overweight.

    What else... oh yeah, Asian people tend to eat rice, not wheat/corn starch/fructose. Probably not as much rice as you'd think. American people consume unbelievable amount of wheat/cornstarch/fructose. They are everywhere in USA. 95% of food at stores are from them...

    Ancel Keys dazzled me as well when I actually took the time to review his work.  Reading his 1385 page The Biology of Human Starvation was quite an enlightening experience, and highlighted the integrity of Keys as a laboratory scientist.  Sure, he rushed to conclusions with the lipid hypothesis, but can you blame him?  I'm sure it seemed obvious and irrefutable at the time that he noticed cholesterol in the arteries of heart attack victims while noticing that fat tended to raise cholesterol levels.

    But it wasn't any more flawed than blaming carbohydrates for all of mankind's problems either, as the biggest carb-eaters on earth remain the healthiest and longest-lived peoples, and high-carb/low-fat diets continue to drop fasting insulin and glucose levels in clinical study.    

    And Keys lived the good life until the ripe age of 100. It's unlikely that any low-carb author/blogger will live more quality years than Keys.

    There were several things I liked about the Fathead documentary. It pointed out the weaknesses of Supersize Me, it outlined many of the problems of the lipid hypothesis, it presented a clear explanation of why low-carb can be effective for both weight loss and cardiovascular health.

    Things I didn't like? Fathead had a clear agenda - to promote Libertarian politics and ways of thinking. As such, Naughton was obligated to place primary blame for all problems on government. Sure, government has a role to play. But if the scientific community had it's act together, government would follow. If we talk about other public health issues (smallpox, tuberculosis, goiter), then we must acknowledge that government can do things right sometimes.  

    Also, there was a disconnect between the 'common sense' of the people and the scientific explanation that was offered. Sure, people know that fast food meal has more calories than a carrot. So what?  If people have that common sense, why is obesity, diabetes, and heart disease so prevalent? I don't think he really answers that. Does common sense tell people that a large plate of pasta is equivalent to eating a cup or two of sugar? Does 'common sense' also tell them that saturated fat is bad, or that to lose weight, they simply need to eat less and exercise more?

    This may be a simplification for why Asians may have less heart disease, but it simply could be because of the use of red yeast rice in many of their foods?

    Curcumin is a component of turmeric.  Koreans and Japanese don't consume it, except in fast-food type curry dishes.  Most of China's major cuisines do not use the spice either.  It is South and Southeast Asians who use it, and Indians have notoriously high rates of heart disease and diabetes.

    As for North Korea, the semi-starving country dependent on foreign aid isn't exactly representative of Asia.  Prosperous neighbors Japan and South Korea have the lowest obesity rates in the OECD.

    Very fascinating info on raising Vitamin D status and CAD below. People who had their 25(OH)D up to 30 ng/ml from 19 ng/ml got the benefits and in the other study 43 ng/ml level seemed optimal yet extra benefits were not seen in, say, 60 gn/ml:

    There was, perhaps, a misunderstanding on Ted's part. We're from England where we term Asian as Indian, Pakistani or Bangladeshi and call the Japanese, Chinese and Koreans individually.

    The core reason of increased heart disease in South Asians probably is partly vitamin D deficiency caused by a conservative dress sense in a sunny climate. India also has a lot of air pollution.

    Many Asian foods (and I mean all of Asia now) use similar ingredients; in fact one Japanese dessert looks and tastes exactly like a Indian/Pakistani one (how that came to be - I don't know). South Asians though eat chapattis (wheat) quite commonly, and from what I gather there isn't a large wheat consumption in East Asians.

    Yes, as Anonymous above mentions, Naughton's political ideology  
    distorts his views. That actually seems more important to him than the issue of diet in Fat Head, which is why he expends so much effort defending Fast Food companies. Witness the part where he holds a huge bucket of French fries
    (think about how many carbs are in that!) and rants something to the effect of:
    "If they want to sell me a huge bucket of fries for 50 cents, and I want to buy it, it's no one's business to tell
    us we shouldn't."
    I'd imagine most readers of this blog are interested in diet and health, not political ideology, so overall Fat Head will probably not appeal to them.

    I used to be uninterested in anything political until I got interested in diet and health care.  The idea that a nanny government could dictate what I can and cannot eat is quite frightening, especially when you consider what the establishment thinks is healthy.  I personally do not want to eat french fries but if we don't object to the government making french fries illegal, who is going to stop the government from banning "artery clogging" coconut oil or outlawing meat?

    Yeah, that is the paranoia talking. After 40+ years of research showing the dangers of smoking, tobacco is still legal. Government is not going to outlaw meat, and I question the good judgment of anyone who suggests that they might.

    I lean heavily toward low carb/paleo and think the "conventional wisdom" is full of holes, but I don't think "Fat Head" does a good job (at all) of advancing the argument to the uninitiated.

    The attack on Morgan Spurlock is misguided, and Naughton's counter-experiment proves nothing.  Spurlock went on an extreme binge which everyone, including Spurlock, expected in advance to cause weight gain and other negative effects ("duh"), which he wanted to document on film.  It was more of an exercise in "performance art" than in science, and meant to simply to provoke the viewer into the thinking a bit about the possible consequences of regularly ingesting the same kind of food over a lifetime.

    Naughton, on the other hand, takes in an actual caloric deficit, with restricted carbs, and regular exercise, and then experiences a weight loss.  How does Naughton's experiment in any way "rebut" Spurlock's?  And, given the fact that Naughton goes on to argue that restricting carbs is more important than lowering calorie intake, his own experiment is useless to prove either strategy, since he cut intake of both calories AND carbs.

    The film is poorly organized and produced, and is undermined at every turn by the injection of sophomoric humor.  In a typically tedious sequence, the snarky Naughton asks people on the street if they have ever collapsed with a heart attack immediately after eating fettuccine alfredo.  Tres dumb.  Especially when you consider that a plate-full of pasta smothered in cream, butter, and cheese is a food that both low carb and low fat eaters would want to avoid eating often.  In one of his failed attempts at humor (in a scene showing his own wife in bed), she asks if he is a moron, and in that moment she seems to speak on behalf of the viewer.

    Worst of all is the ongoing anti-government Libertarian ideology that underscores Naughton's narrative.  He argues that anyone "with a functioning brain" can make proper food choices, but at the same time argues that the public has been deluged with mountains of false information and bad advice for decades.  The film is littered with such logical inconsistencies.  Naughton's gratuitous political agenda shows up in some bizarre assertions, like when he argues that higher tendency toward obesity among the poor is merely the result of a predisposition among non-whites toward "thicker" bodies, and the assertion that court-mandated busing to achieve racial desegregation contributed to overweight school children.  These theories simply detract from the credibility of the diet and health science he eventually discusses.  Naughton is entitled to whatever political views he wishes, but injecting them into a documentary about nutrition and health does nothing to advance an essentially purely scientific subject.

    At his blog and in interviews like the one above, Naughton comes off considerably better than in the amateurish film that he actually made.  If you know anyone "with a functioning brain" that is still clinging to the conventional wisdom that you'd like to convert, showing them "Fat Head" may not be the best way to get them to become more open-minded, thanks to the many mis-guided and unhelpful aspects of the film.

    But they are trying to shut down raw milk, continue to protect Monsanto and not include GMO in nutrition labeling, and continue to put up barriers and regulations that effectively hurt small local and sustainable food producers.  The result is that soon all food will be GMO/CAFO!

Why do morphine-blocking drugs make you lose weight?

Why do morphine-blocking drugs make you lose weight?

Naloxone (IV) and naltrexone (oral) are drugs that block the action of morphine.

If you were an inner city heroine addict and got knifed during a drug deal, you'd be dragged into the local emergency room. You're high, irrational, and combative. The ER staff restrain you, inject you with naloxone and you are instantly not high. Or, if you overdosed on morphine and stopped breathing, an injection of naloxone would reverse the effect immediately, making you sit bolt upright and wondering what the heck was going on.

So what do morphine-blocking drugs have to do with weight loss?

An odd series of clinical studies conducted over the past 40 years has demonstrated that foods can have opiate-like properties. Opiate blockers, like naloxone, can thereby block appetite. One such study demonstrated 28% reduction in caloric intake after naloxone administration. But opiate blocking drugs don't block desire for all foods, just some.

What food is known to be broken down into opiate-like polypeptides?

Wheat. On digestion in the gastrointestinal tract, wheat gluten is broken down into a collection of polypeptides that are released into the bloodstream. These gluten-derived polypeptides are able to cross the blood-brain barrier and enter the brain. Their binding to brain cells can be blocked by naloxone or naltrexone administration. These polypeptides have been named exorphins, since they exert morphine-like activity on the brain. While you may not be "high," many people experience a subtle reward, a low-grade pleasure or euphoria.

For the same reasons, 30% of people who stop consuming wheat experience withdrawal, i.e., sadness, mental fog, and fatigue.

Wouldn't you know that the pharmaceutical industry would eventually catch on? Drug company startup, Orexigen, will be making FDA application for its drug, Contrave, a combination of naltrexone and the antidepressant, buproprion. It is billed as a blocker of the "mesolimbic reward system" that enhances weight loss.

Step back a moment and think about this: We are urged by the USDA and other "official" sources of nutritional advice to eat more "healthy whole grains." Such advice creates a nation of obese Americans, many the unwitting victims of the new generation of exorphin-generating, high-yield dwarf mutant wheat. A desperate, obese public now turns to the drug industry to provide drugs that can turn off the addictive behavior of the USDA-endorsed food.

There is no question that wheat has addictive properties. You will soon be able to take a drug to block its effects. That way, the food industry profits, the drug industry profits, and you pay for it all.

    BTW, naltrexone is also used to treat alcoholism in protocol known as The Sinclair Method.  You take the naltrexone an hour before drinking and then drink normally.  The naltrexone blocks the opoid receptors in the brain and the endorphins released by the drinking find no room at the inn.  Over time, the addiction is extinguished.

    I do not think I could have made up something like this! If I could I would be very rich, and maybe own a Big Pharma company or two.

    BTW, awhile ago, I read about a clinical study done in the UK. It had three groups of heron addicts - one group stayed on heroin, another was given methadone, the third was given a placebo (that they were told was methadone).

    Not surprisingly, the first group remained addicted to heroin, and the second group remained addicted to Methadone. The third group ALL got over their previous addiction to heroin, and with NO withdrawal symptoms, NONE, not one of them.

    Some commentators pointed out that The Heroin Establishment has a very large financial interest in keeping the story alive that heroin is hard to stop.

    I also know someone who was addicted to heroin. But, he realized that he was messing up his life (lost his wife, kids, etc). So, just stopped taking it - NO withdrawal issues, NONE.

    It's not clear to me how much of this is intentional, i.e., is wheat now a ubiquitous component of processed food precisely because of its addictive potential?

    Eating wheat bread by itself is not very addicting but if sugar is thrown in the mix, you can get a nice mood lift.  This is because sugar(along with the wheat) spike insulin which drives tryptophan into the brain, where it converts to serotonin, the feel good neurotransmitter.

    I may experiment.  I have some naltrexone that is about to expire.  I might give myself an injection and see if it makes me less interested in bread.  At the most I might eat two slices of whole wheat once or twice a week.  Would it work for other carbs like potatoes?

    I'm impressed that you've got naltrexone! Please let us know what becomes of the experiment.

    Wheat stands apart for this effect. The only other foods that have been shown to exert a morphine-like effect are dairy products ("caseomorphin"), though the potency is many times less than that exerted by wheat.

    I eliminated grains, switched to Almond milk, cut out coffee and all artificial sweeteners.

    I started LDN in June and have easily lost 23 pounds, a feat almost unheard of in a Hashimoto's patient.

    Just a small amount of some protein and veggies will satisfy me but so could a handful of unsalted nuts.
    My appetite is no longer an issue.
    I would say I don't really have an interest in food anymore.
    I no longer have any blood sugar swings but those disappeared when I eliminated grains. I just feel LDN was helping in the appetite area, now your post confirms what I had been feeling.

    Now that my thyroid medication has been switched ( Armour to Synthroid due to manufacturing issues) and adding Cytomel plus LDN, I feel better.

    I am waiting of lab results to see where my Vit. D level is ( was at 42 aiming for 60) and to see what impact 6 months of no grains has done to my cholesterol.
    I am hopeful!  And that's another thing about LDN, depression is a thing of the past.
      
    My holistic MD thinks because the dosage is so small, LDN is acting in a homeopathic manner.  
    Many Hashimoto's patients have to decrease the amount of hormone they take because of LDN's effect on the thyroid.  
    I should know if my thyroid is happier by the end of the month. It might even be too happy.

    Chet - you say wheat is not addicting. My experience is not proof but when I gave up wheat I had about 3 days of withdrawal symptoms.  I felt really terrible and I was still eating sugar and high carb foods. A few years later I gave up the sugars. Although it took a while to lose the cravings for sweets, I did not have a period of feeling ill like I did when I gave up wheat.  

    Giving up wheat eliminated my depression. The tiniest amount of accidental wheat causes my mood to drop for a few days.

    11/12/2010 6:22:05 AM |

    Wrong explanation. By antagonizing opioid receptors, naltrexone disrupts flow in reward circuit. Which we know is central to the development of addiction. Wheat or no wheat. The weight loss appears to be at least in part something else. In combination with buproprion (AKA Zyban, an effective quit smoking drug) it significantly reduces food intake (by blocking hunger signal and reducing cravings). Again, wheat or no wheat.

    The diabetes guru Dr. Bernstein has written about low dose naltrexone therapy (LDN) to help diabetics lose weight.  Have you used LDN with your patients?  I understand that a low dose of naltrexone taken at night at first inhibits endorphin release and then stimulates it.  Presumably, increased endorphins eliminates the need for addictive foods and lowers inflammation.  Your thoughts?

    There is a Scientific American article that says negative emotions and pain-induced negative emotion are processed in the same brain areas so pain medication also relieves emotional pain.

    If wheat has opiate like effects, it might explain "emotional eating".
