We need to grow a pair!

Hi Everyone!

Yes. I'm walking the line of crudeness because I'm fed up!  Honestly, if I hear one more client say that it's okay that they're having the bag of chips because they are made with whole grains, I'm going to lose it! Honestly, how do you expect to achieve your goals if you're not willing to take out the garbage?

I'm not even sure who to be mad at any more!  I think we all have some culpability in this mess. Let's take a look at how each group plays a role in the obesity epidemic (both creating it and not helping to solve it).

Consumers/Clients

I think that the current food system is the way it is, because we (the consumers/clients) are a bunch of pushovers (not my first choice of words) who are so terrified to give up our vices like junky foods that we know are killing us that we choose to believe the BS claims that are made by food companies about said food items. For instance, these chips are okay because they are made from whole grains, or these cookies are organic.  I mean, PLEASE!

Message: We vote with our dollars, so don't buy processed food anymore & eventually there will be no market for it and similarly, the cost of good quality, real foods will decrease.

Government


The governments who supposedly police the food industry are absolutely culpable & they are made of educated people, so they are not stupid, therefore, I can only conclude that they are driven by money and secondary gain.  There is no other logical reason why in the face of clear evidence that TRANS fats kill humans by well known cardiovascular mechanisms, that they would impose a law to require that the amount of trans fats within a food product be shown on the label rather than make it illegal for the food company to use that item in the foods they make!  WHAT THE HECK!?  Think about it, governments make money on allowing poor quality foods into the market place & people get sick & then there's money to be made on the treatment of those illnesses (preventable ones).  So tell me then, where is the motivation to stop the cycle.  Nowhere for the governments regulators.

Message: Nobody has your back, other than you.  You need to take responsibility for your own lifestyle choices.  Don't you put your health, life & vitality in the hands of people with more to gain if you are sick than if you are healthy.

Nutrition Professionals

Practioners

The nutrition profession including Dietitians, Nutritionists (practitioners), Researchers & Professors.  All of which work very hard (I know I am one) to tow the company line (i.e. the food groups or pyramids or whatever), and most of them (this is where I consider myself different) do NOT question those concepts, they just keep teaching them.  This is where things become ugly for me.  I have a real Masters degree (thesis-based) & am pursuing a PhD all in Human Nutrition, so I believe I can read, interpret & critically appraise the research.  Unfortunately, many of the practitioners in the profession can not, do not or are not willing to do this.  This has lead to the promotion of the low fat diet for instance for the last fifty years or so.  You can see my post on some of my issues with the low fat diet and why that's a huge problem.  And the thing is, the evidence is out there to lead practitioners away from this but most are either too busy or just don't bother to review it.

Researchers

This brings us to researchers and professors. Researchers & Professors are, for the most part positions that are research driven and depend upon production & publications for their institution.  Unfortunately, Western medical research practices are based on supposed gold standards (i.e. randomized clinical trials) that really only work for pharmaceutical drugs, no coincidence that the majority of medical research is funded by these companies and that most medical decision trees produced for physicians and psychiatrists either end at or have as a major part of their treatment a pharmaceutical drug (that's for another rant, though).  I have many research colleagues and friends who consider the current state of nutrition research a joke.  I unfortunately have to agree with them.  They are mostly in the physical sciences like chemistry and physics, both of which I have minors in.  The major difference in my opinion is that those physical sciences have a unifying theory, which guides all research in that discipline to be in line with those principles.  In medical & health research it's more of a crap shoot of random trials & outcome measures.  Many will argue that there is no medical unifying theory, but that is crap!  The unified theory of biology should be and is EVOLUTION!  I talk about that unifying theory in a prior post here.  If nutrition researchers would simply ask does this study/finding/research question that I am proposing make sense in light of evolutionary biology, then this would prevent millions of dollars from being wasted on stupid projects that provide zero insights into human health & disease.  And by the way, food companies are also spending billions of dollars to fund research projects.


Professors

Professorships are research-dependent and therefore all of the research criticisms discussed above apply.  Additionally, however, most of the time there is a regulating body (i.e. college or other guiding body) that dictates the competencies and content that are required to become a certified health professional.  Unfortunately, these practice recommendations are based on the assumption that the last fifty plus years of lifestyle based research has been sound and that the principles of many of the early low fat proponents was correct (which is now known to be false).  Yet, each new generation of nutrition, health and medical practitioner are taught the same strategies to prevent and manage/treat cardiovascular disease, diabetes, kidney disease, etc... without any regard to human evolutionary biology.  This is absolutely a critical mistake and the most frustrating part of all is that this is a relatively easy one to fix.

Message: You can't always put your faith in credentials.  Just because someone has a certification or degree, doesn't mean they're good at what they do or even know about or truly understand the current research, it just means they were able to complete coursework & do well on a test. I am a certified health professional, I have many colleagues and only some of them truly understand the current research. Be sure to do your own research and then discuss it with your certified health professional.  If they are completely closed, fire them & find another who is more open and versed on the research.

So. What the heck can we do about it?

It's an easy fix, but not a quick one.  I learned everything I could (and still am by the way) about evolutionary biology and then use these principles to filter all of the latest research findings through and see which ones still make sense or try to figure how they might fit.  Also, I use these evolutionary principles to adjust my prevention and treatment protocols so that they are more in line with evolutionary biology.  There are many non-certified Western and Alternative medical practitioners that have been doing this for some time, I applaud the honest ones for doing this.  I think it's time that we in certified Western medicine caught up!

Message: It's through this practice of selecting professionals that are more open-minded & versed on the literature, that health professionals will ultimately expand their knowledge and be accountable to you, the client.  Also, we have to stop always citing old studies as the basis for our current treatment practice, research question or curriculum and seriously attempt to integrate the evolutionary biology approach.


Thanks for reading my rant!  I hope you found it useful as well as entertaining!  Honestly, I feel better for having wrote this, so thanks for giving me an audience.

Have a great week!

Take care,

How to Heal your Gut & WHY!!!




There is more and more research suggesting that a "leaky gut" could be the underlying cause of many diseases that face modern humans and that it can perpetuate inflammation in the body that wreaks havoc on general health & well-being.  In order to discuss this further, we need to start with some basics.
The basics:

1)                    The gut is essentially a long tube that forms a 
barrier to the outside word that selectively allows
penetration of essential nutrients, vitamins, etc… that
we need to survive and thrive. Many hormones are
secreted by the gut and interestingly these hormones
can have both peripheral and central effects.

2)                      As mothers approach birth their
vaginal population change in order to expose the baby
to as many good bacteria as possible - this is evidenced
by lower numbers of good bacteria in the guts of children
from c-section birth.

3)                      The gut houses approximately 100 trillion 
bacteria and this population of bacteria is around 10 times 
that amount of human cells present in our body (3.72 x1013)-
this number is so great that it's becoming more apparent that 
these bacteria might be able to stimulate us to do what they want
(i.e. Food cravings/choices like carbohydrate cravings or PICA).

4)                      Gut flora promote normal GI function, provide protection from infection, regulates metabolism & comprises more than 75% of our immune system.

Our modern lifestyles put us at risk for lowering the good bacteria normally colonizing our guts. Chris Kresser outlines these in his blog:

·            Antibiotics and other medications like birth control and NSAIDs
·            Diets high in refined carbohydrates, sugar and processed foods
·            Diets low in fermentable fibers
·            Dietary toxins like wheat and industrial seed oils that cause leaky gut
·            Chronic stress
·            Chronic infections
Antibiotic therapy will essentially hit the reset button on our good bacteria, indiscriminately wiping them out. It then becomes critical that we repopulate our gut with beneficial bacteria and that’s where I believe most of us including Western Medicine practitioners drop the ball.

If the intestinal barrier becomes permeable (leaky gut), large protein molecules escape into the bloodstream that normally would not have penetrated. Since these proteins are not recognized by the body, the body mounts an immune response to them and attacks them. Studies show that these attacks can play a role in the development of autoimmune diseases like Hashimoto’s, Type 1 Diabetes, Multiple Sclerosis and more. This immune response brought on by “leaky gut” has been shown to affect not only the gut itself, but also other organs including the skeletal system, pancreas, kidney, liver and the brain. Additionally, it’s been shown that “leaky gut” can manifest problems in the skin and heart.

What you can do to make sure your Gut stays healthy?
  1. Eliminate exposure to toxic substances in food.   Substances to try to avoid:
    • Cereal grains (especially refined flour)
    • Omega-6 industrial seed oils (corn, cottonseed, safflower, soybean, etc.)
    • Sugar (especially high-fructose corn syrup)
    • Processed soy (soy milk, soy protein, soy flour, etc.)
  2. FODMAPs intolerance – Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols – these are short-chain carbohydrates that are incompletely absorbed in the gut & can be easily fermented by Gut bacteria – the fermentation & osmosis caused by these undigested sugars cause major IBS symptoms such as gas, pain & diarrhea.
  3. Use Fermented foods including Sauerkraut, Kimchi & Kefir, etc…
  4. Use high-quality, mutli-species probiotic supplement after antibiotic use.
  5. Manage your stress – Lots of research links gut health with emotional health & well-being!
    There's so much more that could be discussed, but I'll leave that to the experts.  If you're interested in having a full assessment done on the state of your gut health, track down a good functional medicine doctor in your area who can help you handle this.  Two sites that can help you are the Paleo physicians network & Primal Docs.
Until next time, make sure you're taking care of your gut & the Trillions of bacteria in it, and in turn, they will take care of you!

REDEFINING WHY PART 2

Back in part 1 of my 2 part series on REDEFINING WHY, I attempted to define how I was able to be lean & athletic and remain that way through incredible stresses up to about 10 years ago and more importantly why this seems more difficult currently (at 41 years).  In part 2, I’m hoping to take you through the process of establishing my new WHYs and creating my specific goals for the next few months. This might take this post & one more.

Out of Date WHYs:

A) Be the leanest & fittest man I can be in order to attract the woman of my dreams.
B) Be as healthy & strong as I can be in case MS strikes me down, I will be in better position to maintain strength & function, etc…
C) Be Warrior Fit.
——————————————————————————
Why these WHYs are obsolete to me now:
A) I’ve met & married the woman of my dreams.
B) My mother passed away of complications relating to her (30 year bout with) MS 2 years ago & my priorities have shifted from avoiding disease, to earning a living & caring for my family.
C) I have not consistently practiced martial arts for the last decade and a half & I’m no longer as focused on preparation for spontaneous kumites.  
—————————————————————————————

Tony Robbins discusses 6 Master Steps to Change in a Powertalk session. I’ve adapted those here to walk you through how I developed my WHYs & how I intend to change my behaviors and start heading towards the attainment of my goals.  


6 Steps to Change:

1) Decide what DO you want & what might prevent you from getting it.
2) Create leverage (on yourself) to make the change a must.
3) Interrupt the current pattern.
A) Visualization
B) Experience
4) Implement the change using a positive behavior in place of the negative one (if applicable).
5) Condition the new behavior pattern, so it remains consistent.
A) Visualization
B) Role-Playing
6) Test the new behavior (pattern).
A) Visualization
B) Experience

Newer, more relevant WHYs:
A) Be the best living example of healthy, lean and strong man who is living the Paleo/Primal lifestyle for my family, friends, clients & the world.
B) Be a living example of what kind of change is possible through a well planned Paleo/Primal lifestyle for my family, friends, clients & the world.
C) Be the best example of health, fitness & longevity that I can be for my kids so they will be proud & strive to emulate my lifestyle.
D) Become as Warrior Fit as I can because I want to be able to defend my family at any moment, whatever comes.
These are WHYs that touch me more viscerally currently, so I know they’ll be more effective.

Now, if only this lifestyle could morph my face into Jason Statham's (at right) then my acting career would really take off!!
My Leverage:

For making the changes - I must achieve these changes because I have always been a man of my word. I am a healthy, lean & fit man who is a living example for those around him of what a healthy lifestyle can do. I now understand the importance of living a Paleo/Primal lifestyle & need to now implement these principles fully into my lifestyle in order be the living model of health, fitness & longevity! I need to become a living example of health, fitness & longevity & the power of the Paleo/Primal lifestyle in order to effect change at the policy level & to lead the charge amongst my fellow RDs.
I need to be a living example for my family and especially my kids in order for them to strive to emulate my lifestyle!  

Against not making the changes - If I don’t achieve my goals and successfully implement these lifestyle strategies then I will lose the respect of my friends & family and most importantly myself. My business & services will not thrive if I can’t be a living example of my lifestyle strategies. I will not be able to successfully effect changes at the policy level & amongst fellow RDs unless I am a living example of health, fitness & longevity!

My specific goals: Over the next 4 months, I will:
1) lose 4 inches off my waist (aiming for 1/2 inch every 2 weeks).
2) go to at least 2 CrossFit classes per week & will add in physical play activity (increasing weekly as weather here in Canada improves - horrible winter here this year.
3) consume a Paleo/Primal diet daily with on non-Gluten containing one cheat meal per week.
4) consume 100 g of carbohydrates or less daily.

These goals are mostly behavioral, meaning that I’m able to track my progress daily by seeing if I’m on track or not using a behavioral checklist. I discussed this in a previous post.
Although, this doesn’t guarantee success, since it can't remove the daily stressors of a newborn + a 2 year old, working full time, pursuing a PhD (due end of 2015), blogging & running my business; these goals should increase my odds for success because of the 6 keys to psychological success as reported in Prev Medicine in 2004 which were:
A) Using Proven Strategy - Paleo/Primal has worked for thousands, why NOT me!
B) Using all available resources - Quality food obtained & source identified, Kitchen & Pantry cleaned out, Cooking tools ready to rock.
C) Integrated Social Support Structure for behavior change - My wife is doing this with me + accountability to my readers = ultimate support system.
D) Self-Efficacy - my goals are broken down into smaller chunks to gain momentum & confidence.
E) Greater Outcome Expectations - 4 inches is significant.
F) Adequate time to form habit - I’m giving myself 4 months to fully embrace the lifestyle, but know that actual permanent change can take 1-2 years to become ingrained.

Well, I'm off & running (pun intended).

If you would like to do this also, feel free to share your step by step goals in the comments section!

Let’s rock this!

Take care,

Dan T

Hunger. The Primal Trigger!

I was listening to a podcast by Maximusmark and he was interviewing Art De Vany, who I like to call the Godfather of Paleo/Primal! Anyway, they were discussing some of the concepts in Art’s book The New Evolution Diet, and talked about hunger as a motivation for exercise. Art described studies on mice and how when they were well or over fed they were reluctant to move, but when they were hungry they would move much more. A recent study examined this in male rats and found that ghrelin increased food intake and decreased spontaneous physical activity, while agouti-related peptide (AgRP) and neuropeptide Y (NPY) both increased food intake, AgRP decreased, while NPY transiently increased spontaneous physical activity. It seems that intake of about 15-20% below calorie needs improved physical fitness in mice. It seems that it would make evolutionary sense for humans to become motivated to action (often by hormones or neurotransmitters) in order to be able to fight or flight, or procure food, win a mate, etc… This is interesting, because it’s been shown in human children that excess body weight (overweight/obesity) is associated with decreased physical activity but not the other way around. Of course in today’s modern food system, it seems difficult to eat a diet that is not obesogenic (promoting obesity). 
This got me thinking. There is a massive amount of literature on diet and hunger, specifically the satiety (fullness) effect of many foods. One study examined macronutrient composition on satiety and eating behavior as well as weight loss concluded that there were no significant differences between a high carb and a high protein iso-energetic diet protocol, however, this study did not look at carbohydrate restriction, which have been shown to absolutely associate with greater fat loss and satiety in both controlled studies and self-reported populations. Furthermore, it’s been shown that low fat diets adversely affect energy availability in the weight maintenance phase & therefore shouldn’t be used (at all in my opinion) over the long term. Furthermore, a review of all the popular diets concluded that the low carbohydrate diet protocol was the most effective at producing fat loss and metabolic improvement, at least in non-diabetic, premenopausal overweight/obese women.  I know from my experience working with thousands of clients seeking fat loss that most start out being incredibly hungry all the time when they are "dieting".  Obviously, because they are doing it wrong!  In this case, hunger, a primal cue that was essential to our survival, becomes somethings that prevents us from obtaining our goals!  That means that our approach is wrong.

There has been much research into the physiological and biochemical pathways that regulate hunger and attempts by science to control or suppress hunger, more often than not this involves a marketable product. Probably the most interesting thing to me is that a significant chunk of hunger research was done & contributed to by BIG FOOD companies. Now from a business perspective this makes sense because they profit from consumption of food products and any information that helps a company drive users to consume more will make them more profitable. Unfortunately, these "good business practices" by the food industry translates into health concerns for us including but not limited to overweight, obesity, diabetes and heart disease. In essence, the current strategies used by food companies and allowed by governments are making us fat, sick and eventually dead! Therefore, we need to limit our exposure to as many of the “processed foods” as possible.

I have created a list of 4 groupings of foods that I consider processed. Obviously, if you are a Paleo purist, then you will not want to incorporate most of these, but if not, then I would suggest limiting your intake of these processed foods to not more than 3 servings per week and only if you are able to achieve your goal of optimal performance, health and longevity while doing so! There are literally hundreds of thousands of lists of processed foods out there, so rather than re-invent the wheel & add to the confusion, I’ve attempted to add general classifications of foods as well as rules that should tip you off that a particular food is “processed” significantly.
List of Processed Foods:
1) All breads, cereals & pastas - these “plant foods” are mostly GMO & are often milled (finely ground) and then pressed into shaped & cooked. In a nutshell, no pun intended, they are quite highly processed and far removed from their natural state. The only benefit that has been shown by this food group is that the fortification with folic acid has helped to decrease the incidence of neural tube defects and unfortunately, folic acid that is added in many countries has been shown to be associated with increases in colorectal cancer prevalence. This is NOT CAUSAL, but it should raise some flags. 
 
2) Sugar and sweeteners - these are highly refined products whether they have a “calorie value” or not. Both sugar and sweeteners have both been associated with weight gain. Furthermore, in my experience, clients who try to lose weight while using sweeteners are often unsuccessful or only successful for the short term. The way I would normally advise a client is that if they are currently using sugar, they need to wean down to nothing eventually. If they want to use a sweetener (artificial or natural) in the process of doing this over say a month or so, then that’s fine. But honestly, it only prolongs the inevitable, which is essentially a feeling of going cold turkey and cravings for carbs, that one must push through in order to reset the palate.
3) Liquid, pasteurized dairy - firstly, we are designed to drink human milk, and only when we are infants. Secondly, we are designed to drink raw milk, with enzyme and healthy bacterial activity, etc… Pasteurization destroys some pathogens but also destroys enzymes and kills off beneficial bacteria present as well as other micronutrients present in raw milk, including decreasing the solubility of the calcium present. This is not surprising due to the heat-lability of many proteins. Importantly, the diet of the milk producing cow needs to be considered. If that cow is consuming grass as it is designed to do, then the milk fats are healthy, whereas if the animal is consuming grains, which it is not designed to eat, then it is often sick and requires antibiotics, so the combination of pesticides, GMO grains and the pro inflammatory fats from the seed oils lead to dirty milk fats, which. If you can find a clean milk source raw or pasteurized, then use it if you like and don’t be afraid to go full fat dairy in that case. Of course, raw milk is currently illegal in North America, although, it’s the norm in other countries. I would never suggest that the current food system with mass produced dairy shift to raw production, as that would be crazy, however, if the food system shifts to more local producers (once again) and you are able to legally acquire it from a local farmer’s cow, then GO FOR IT! 
4) Fruits & Vegetable juices - specifically, I’m talking about store bought ones that are not labeled as raw. North American food safety protocols dictate that any fluid sold in stores that was once living has to be pasteurized including dairy and fruit & vegetable juices. The problem is that many of the protective benefits that are known about fruits and vegetables are believed to be eliminated be pastuerization due to the high heat. That would explain, why studies have shown that people who consume whole fruits and vegetables live longer & are healthier overall, but these benefits are not present in store bought juices because of the heating
I hope that you are able to use this list to help you achieve your goals!
In my opinion, it's not a conspiracy, it's just about making money & that includes the government.  Hopefully, one day, using research into human evolutionary physiology to elicit the response of incresaing consumption of foods, especially in light of the fact that they are destroying our health, will be illegal; but until then we have to stand on guard for ourselves and our families! Let’s not reward food companies for researching hunger triggers & using it against us!
Until next time! Remember to join the MERF movement (I MUST EAT REAL FOOD) & live and play life to the fullest!
