Milestone: 200000 Page Views

Thank you dear readers for coming to see us and read along as we learn about health, fitness and nutrition!  If you are in the Brunswick area, come join us for CrossFit, we look forward to seeing you.

I feel funny celebrating page views when some gyms get that many hits a month (in the DC area for example).  Writing an obscure blog from a small town to varied readers with an interest in paleo and CrossFit makes 200,000 a big number to me.

Perfect Health Diet

"[We held a retreat] and one of the things that came out really quickly was it turned out to be super for weight loss.  And again it wasn't designed to be a weight loss program, you could eat as much food as you wanted.  And yet we had great weight loss results.  So I started thinking more about why is this working so well for weight loss, and started thinking about the obesity problem."
In the video, he gets into two questions: What are the most puzzling issues in weight loss?  What are the most important facts?
Pull it up on your phone and drink it in.

Saturated Fatty Acids

The linked article contains a nice analysis of health correlations related to saturated fatty acids (SFA). SFA's have been vilified as causatory agents in heart and other vascular diseases.  However, the analysis points out that the correlations with disease are strong with SFA's that are produced by the body as a result of carb, sugar and alcohol ingestion, vice ingestion of fats.  By contrast, blood SFA's that are associated with fat ingestion are inversely correlated with the aforementioned diseases.  In a way, this is just a BFO - blinding flash of the obvious - as it's been long known that blood triglycerides, including the SFA palmitic acid, are very well correlated with disease and metabolic syndrome. The nice thing about this analysis is it finds the same conclusion via a different methodology.

Simplest Change

Each of our clients wants to lose fat, except maybe one.  Most are already working within the paleolithic model of nutrition.  Some are having spectacular results, and that is putting smiles on both of our faces.  Some are stalled out.  Today's post is about the simplest change one can make to reaccelerate fat loss.

That change is to have a breakfast of only protein (some, 15-30 grams) and fat (a lot).  Why will this help?

First, let's get into how you body fuels itself.  The number two metabolic priority (in terms of urgency) is getting sugar to the brain.  The brain needs approximately 600 calories worth of fuel daily.  That's about 25% of the total caloric requirement for most folks.  If the brain does not get the necessary fuel, it will cease to function, you will fall down, and the ghost might leave the machine, depending upon how fuel deprived the brain is.  To keep this from happening, you were engineered with a redundant fuel system, that allows you to make brain food from fat, carbs or protein.

Most of your body runs best on fat as fuel.  The engineer's intent seems to have been that you would not need to eat or store much sugar, and that the sugar (not in large supply until very recently) you ate or stored would be used primarily by the brain.  The first contingency for lack of available carbs/sugar is that your liver will convert fat into ketone bodies, which can be an alternate fuel for the brain (in fact, there's some evidence the brain is most healthy when fueled by both sugar and ketones).  This system is what lets a person survive day after day with no food available (remember those stories of 60+ days in a life raft?).  If you ever face that situation, the body will also catabolize muscle to make protein and sugar for the brain.  So in all you have three ways to store energy - fat is the biggest source and the best fuel.  Sugar is the smallest source and is a preferred fuel for the brain.  Muscle is the desperation fuel, "for emergency use only."

Now let's get back to why keeping carbs out of your breakfast will help you to burn fat.  First, all night long, since you are not eating, your body has to start converting to fat burning (you know people have a serious sugar problem when they cannot sleep through the night without sugar cravings).  When you "break your fast", if you give the body sugar, it will stop running on fat.  If you give your body too much sugar, it will get busy converting that sugar into fat.  If you give yourself a moderate protein, high fat breakfast, this can keep your hunger at bay but let the body keep burning stored fat for brain fuel.

So the easiest, simplest, change to start burning more fat is to have a carb free breakfast.

If you want to take this one step further, stop eating by 7 or 8 PM.  That way, you may go as long as 12 hours from last meal of the day until first.  That also invites your body to get good at burning fat, and if you don't eat carbs until lunch, that's a 14-16 window of no "carbage".  This kind of carb fasting is very useful for those who want to get healthy and lean.  Why does this help with health?  In short, the number one driver of disease in our nation is metabolic syndrome, which is characterized by loss of glycemic control (that is to say cycling high and low blood sugars).  The above described carb fast interrupts the cycle of excess sugar/carbs, and restores normal blood sugar levels for many who are dangerously close to metabolic syndrome.

This is also why exercise alone does not work for fat loss or health - if you continuously over-eat sugar and carbs, you will not get glycemic control and you will not have your best health no matter how intense your daily workouts are.

If you want to take this another step beyond a carb fast, push your breakfast back by one hour each day, until you can go food free for 14-16 hours.  This path can be risky for some, so if you want to do this, come talk to me first.  You can also search this blog to find prior posts about how to start intermittent fasting.

Are you ready to make the simplest change?  If so, get going and let me know what you learn!

Does Aspirin Stop Cancer

This is a very interesting and relatively brief summary of the topic - the short answer is - "we don't know who will get the most benefit for the new risks."

Elite Athletes Who Do CrossFit | THE RUSSELLS

One of the most common myths about CrossFit is that no elite athletes use it. That’s completely false.
Here are some top athletes who do CrossFit. It’s not a full list. There are 10,000 CrossFit gyms, and we can’t possibly know every elite athlete who trains at them, or who does CrossFit on their own. Also, these athletes use CrossFit as part of their training – it doesn’t replace their specific training. No strength and conditioning program could.

The Importance of Eating Together - ​Cody C. Delistraty - The Atlantic

On the one hand, the topic of this article would seem to be nothing more than common sense.  Folks that eat together are happier and healthier.  This is not new news.  On the other hand, this article shows how difficult it is to "know" anything about the complex animal we call "humans".



"After my mother passed away and my brother went to study in New Zealand, the first thing that really felt different was the dinner table. My father and I began eating separately. We went out to dinners with our friends, ate sandwiches in front of our computers, delivery pizzas while watching movies. Some days we rarely saw each other at all. Then, a few weeks before I was set to leave for university, my father walked downstairs. "You know, I think we should start eating together even if it's just you and me," he said. "Your mother would have wanted that." It wasn't ideal, of course—the meals we made weren't particularly amazing and we missed the presence of Mom and my brother—but there was something special about setting aside time to be with my father. It was therapeutic: an excuse to talk, to reflect on the day, and on recent events. Our chats about the banal—of baseball and television—often led to discussions of the serious—of politics and death, of memories and loss. Eating together was a small act, and it required very little of us—45 minutes away from our usual, quotidian distractions—and yet it was invariably one of the happiest parts of my day."
"Sadly, Americans rarely eat together anymore. In fact, the average American eats one in every five meals in her car, one in four Americans eats at least one fast food meal every single day, and the majority of American families report eating a single meal together less than five days a week. It's a pity that so many Americans are missing out on what could be meaningful time with their loved ones, but it's even more than that. Not eating together also has quantifiably negative effects both physically and psychologically."

This is where the trouble begins.  There's not anything quantifiable about the data the author cites.  This is not good science.  It's just correlation, which does not imply causation.  For example, it's long been known that wealthy people live longer than the poor.  What is not known is why - do they choose better lifestyle variables?  Probably.  Which ones matter?  No one knows.  I'd guess that on the whole they eat better food, smoke less, and sleep more/better.  Guessing is just a small first step in science.

"Children who do not eat dinner with their parents at least twice a week also were 40 percent more likely to be overweight compared to those who do, as outlined in a research presentation given at the European Congress on Obesity in Bulgaria this May."

OK, but why?  Answer:  we don't know.

"On the contrary, children who do eat dinner with their parents five or more days a week have less trouble with drugs and alcohol, eat healthier, show better academic performance, and report being closer with their parents than children who eat dinner with their parents less often, according to a study conducted by the National Center on Addiction and Substance Abuse at Columbia University."

Fascinating correlation.  I'm glad I eat with my family almost every night thanks to my wife's focus on this matter.  But this correlation does not tell us anything about prediction or control, which is what science is about.
