Like a Kid in a Candy Shop: Know Thyself

 
 
Caveman Doctor listened to his last conventional wisdom talk from a nutritionist this week.  He thought this one might be different, as it was titled “Low Carbohydrate, High Protein Diets.”  Using his sense of smell fine-tuned by years of hunting for prey, he could smell the conventional “wisdom” pouring out of this talk and into the ears of its unwitting victims. Caveman Doctor tried several times to discuss actual scientific data with the nutritionist and engage in debate, but each time the speaker could not address his questions.  He got so upset, he let out a big roar and crept off to his cave, i.e. office, to vent.  Then he started writing this on his computer (whatever a computer is).
 
 

“Know Thyself”

This ancient Greek aphorism’s simple yet profound message remains relevant in our modern era.  It is self-empowering, and leads to independent thought and action.  However, some groups, such as the modern conventional diet “experts”, often seem to have a different motto:
 
“We know you better than you do, just take our word for it and do what we tell you.”
 
Hearing dieticians tell people who have trouble with keeping off weight to cut calories, but to continue to eat high amounts of carbohydrates, is unfortunately a common occurrence.  Knowing that this advice does not work, but rather sets people up for failure, anxiety, and even self-loathing, makes it painful to watch it being propagated.  Pushers of conventional wisdom do not refer to data or nutritional studies (if they even know them) but rather fall back on the recommendations.  Such behaviors cause the blood pressure of those of us that review the scientific literature to rise quicker than the blood sugar of someone following our government’s dietary recommendations.
 
 

This is Your Brain on Grains and Sugar

Carbohydrates, especially sugar and grains, raise insulin.  Insulin causes several subsequent biological responses, and ultimately, raises your appetite.  With repeated exposure, insulin has such a stimulatory effect on appetite that it is used as a treatment for anorexia1,2.  It stimulates a part of the brain (the hypothalamus) that causes drastic increases in appetite3, the same area that causes uncontrollable hunger and obesity in children with Prader-Willi syndrome4If insulin will cause appetite stimulation in anorexic patients, what will it do to a room of people who struggle with eating issues?
 
Taking it a step further, a recent study gave rats the option of indulging in cocaine versus sweet saccharin.  Ninety-four percent of the time5, the rats chose the sweet reward over what is considered one of the most addictive drugs in our society.  You read that right, sweet foods may be more addictive than cocaine.
 
Would we tell a drug addict only do a little bit of cocaine?  Yet we are taking people addicted to a substance possibly more addictive than cocaine, and telling them to only eat a little in moderation. And let’s not forget that unlike cocaine, which is taboo and hard to find, carbs are ubiquitous in our society and even promoted as being healthy.  Is it any surprise that our dietary advice fails?  Carbohydrates, especially sugar and grains, are like addictive drugs to our brain stimulating appetite and stimulating the need for more carbohydrates6.
 
Eating them is the ultimate test of willpower.
 

Salt 179x300 Like a Kid in a Candy Shop: Know Thyself

Is this cocaine or sugar? Both look the same to a caveman, only sugar may be more addictive. (It’s actually salt as Caveman Doctor has neither sugar nor cocaine in his apartment).


 
Maybe worst of all, studies show that when women are sad or depressed, they turn to foods with greater than a 6:1 ratio of carbohydrates to protein7.  Like a beleaguered spouse returning to an abusive relationship, the cycle of overeating only gets amplified after failed attempts at moderation with carbohydrates leads to further consumption of carbohydrates to lessen the anxiety and sadness that follow.   The discussion of low-fat versus low-carb takes on a different form when appetite suppression versus stimulation is considered.  Regardless of any discussion of a metabolic advantage of low-carb dieting, it has been shown repeatedly that when dieters are placed on a low-carb regimen, they spontaneously reduce their overall food intake8.  The goal here is to empower people to make changes, not provide them with advice that has been shown to be ineffective and places the emphasis on controlling physiologic urges that are often uncontrollable.
 
Do people want to eat too much?
 
Do people want to overdo it on food?
 
Do people want to be obese?
 
Why can’t they just eat a little ice cream, bread, or candy?
 
Everything in moderation has failed.
 
So let’s stop telling people to do it.
 
Think about the saying “like a kid in a candy shop”.  The modern diet is essentially a modified candy shop, with carbs (i.e., sugar and grains) composing a large portion of every meal and snack.  Let’s break ourselves out of this constantly tempting, draining candy shop and instead eat wholesome foods.
 
Would a cocaine addict try to beat his addiction by only engaging in moderate drug usage?  Of course not, yet once again, there I sat watching the onus placed back on the dieter, not the recommendations.  A member of the audience had it right from the beginning.  Carbs are addictive and many people are addicted.  A more successful approach may be to avoid those addictive foods from the start and instead enjoy filling, nutrient-dense foods that leave you satiated, and not begging for more.  It doesn’t take a degree in medicine or nutrition to see this.  It does, however, take some courage and perseverance to go against the faulty teachings of conventional wisdom.
 
Maybe reduced-carbohydrate dieting isn’t the only solution for some rare groups, but it is likely a great solution for the majority.  As a practitioner of medicine or dietician, ignoring and withholding this dietary option is unfair for your patients and limits their ability to succeed.
 
 

Parting Thoughts

I was addicted to carbs and am not afraid to admit it.  I now know that I am only capable of eating carbohydrate sources in the form of leafy green and colorful vegetables, sweet potatoes, and berries with rare exception.  I admitted my addiction a long time ago, removed it, watched my health soar, and moved on.  Unfortunately, while I moved on, the conventional dietary advice has not – it remains heavily carb-biased.  Let’s try to empower people to admit their addiction and move on, instead of advising them to only do smaller amounts of their drug.
 
If you are able to eat that single piece of bread and pass on the rest of the basket, congratulations – you are unique.  However, if you are like most of us addicts, the best way to handle your carbohydrate intolerance and addiction may be to avoid that bread in the first place, or consume it very infrequently.  Oh, and don’t feel bad if you can’t handle these carbs in moderation.  You’re just like the rest of us.

 

In a battle that can’t be won, identify your enemies and avoid them.  Know Thyself.

    Thanks for the concise set of talking points, Dr. Champ. I had a question, though, about the connection you drew from the rat study about the choice between cocaine and sweets to humans. Although it’s tempting to draw a parallel situation with people’s choices, is it scientifically warranted? I have read that whatever the outcome of a mouse/rat study, it merely suggests an avenue for testing a hypothesis in humans, rather than offers conclusive proof about human reactions.

      Jake,

      You are 100% correct. It is interesting and hypothesis generating but does not prove anything (though it does lend support to some suspicions). However, tests like this will never take place in humans (giving cocaine, etc.) so we do have to extrapolate at some point (keeping in mind we are merely extrapolating of course). Until level I evidence exists, much on this topic is speculative, unfortunately level I evidence may not be coming anytime soon.

      Thanks for the great comments.

    Thanks for another great post Caveman Doctor.

    I followed up on your references and also came across a review of the evidence for sugar addiction (behavioural and neurochemical effects). It was published in Neuroscience and Behavioral Reviews 32(2008) 20-39. An interesting review which really drills down to the neurological effects of sugar that mimic opiate drugs.

    Food for thought!

    CD,

    Another great post here.

    The part about women and comfort foods reminds me of an ad for Special K cereal, promoting it as a “comfort food” – it fits your pattern precisely. Women have been particularly brainwashed into the low fat high carb diet, yet the most carnivorous women I have known have also been the most healthy/energetic/happy (though not always the thinnest, but women aren;t meant to be thin anyway)

    I would think what would be an entirely acceptable comfort food for low carb/paleo diets would be 90% cacao chocolate.

    On the topic of sugar being addictive, I think it might be more accurate to say “sugary foods”. Try (white) sugar water alone, and it is strangely unappealing. Ad any kind of flavoring – vanilla, cream, coffee, fruit juice, and it becomes hyper palatable.

    Stephan Guyenet had a really interesting blog post about a mice experiment that showed sugar had to be “palatable” to be fattening.
    http://wholehealthsource.blogspot.ca/2012/06/new-study-demonstrates-that-sugar-has.html

    And, Seth Robert’s Shangri-La Diet is based on consuming non palatable calories – sugar water, olive oil, flax oil and so on.
    http://sethroberts.net/science/

    Some remarkable results here, that support the theory that the stuff has to be palatable to be addictive and cause weight gain. And, of course, the part of the object of almost any food preparation is to make it as palatable as possible.

    We live in a world where every food ahs to be a gastronomic experience, and often the easiets way to make it taste better is to add sugar!

    But the best way to make it taste better is to add – butter!

    And if there is no sugar there when you add the butter (e.g. green veg) then all is good!

    Cheers,

    Paul

      Paul,

      Thanks for the insightful comments. I agree with your comfort foods comments and think dark chocolate is a decent go to comfort food for many (including myself). The whole addictive nature of food is a heterogeneous bag of factors with food palatability definitely playing a big part. There is still something about grains, whether it is opioid receptor activation or what, that turns the addictive switch on overdrive regardless of palatability. Even sourdough or other breads that are not palatable at all to me (and others) seem to flick the switch. It is definitely a fine interplay of many factors and I totally agree with your last comment that we must figure out ways to bypass the reward system to aid people in eating healthy.

      Thanks again!

        I’m not so sure we have to totally bypass the reward system (though that is exactly the basis of Seth’s method) so much as allow reward for different things. I am speaking here of the demonizing of animal fats.

        here I agree with Robert Lustig’s point -once the food mfrs were told to remove animal fats (which taste good) they had bland food and so resorted to sugar to make it taste good.
        The results of that switch are undeniable.

        So back in the day (a century ago) when people enjoyed butter/animal fat with everything and sugar with nothing (almost) people were quite healthy, even with their reward systems working.

        Part of the problem is that the hyper palatable sugary foods are also the cheapest, so you have two reward systems working together.

        Sad part is that butter is actually one of the cheapest $/calorie foods you can buy. Using Seth Roberts amount half a stick/day (60g)- which provides 400 calories, and costs 50c to $1 depending on brand/quality. That is 1/6 th of the day’s calories, plus a slew of valuable vitamins, including K2, for a bargain, and far cheaper than any supplement.

        It seems that the butyrate in butter has some very beneficial properties too…

        Best,

        Paul

    Paul,

    Great point and I agree 100% – we need to switch to nutrient dense foods as they are more filling and more nutritious. Grass-fed butter is defintiely right up there (and apparently so is bacon per a presentation at the recent Ancestral Health Symposium).

    Take Care,
