Protein…The Essence of Existence!.

Speed Training and Dynamic Warm-ups Revealed.

-Excerpt from an article I read, thought I’d share…link below*

Picture a morbidly obese mouse, you know, the ones companies use to show as the “before” picture when marketing certain products.  Anyhow, let’s call him Jumbo. Jumbo is unique – he’s an ob/ob mouse. This is a mouse that becomes a type II diabetic, can’t stop eating, and packs away body fat like crazy. No matter how much you feed him, he won’t stop.
Poor Jumbo has a mutation in the gene coding for leptin – he’s totally missing it! His fat cells can’t properly communicate with his hypothalamus because he has no leptin. If you inject Jumbo with leptin, he’ll stop eating and lose weight, but the solution isn’t so simple for us non-mutants.  Most obese people don’t have missing or mutated leptin genes – they can make plenty of it. The problem is that in spite of leptin still finding and binding its receptors all over the body, no downstream message is sent. The system that senses leptin is broken.
This is called leptin resistance, a condition in which the brain can’t determine when body fat is at an okay level. The fat cells are sending leptin out to the hypothalamus to signal that fat stores are full. Leptin binds the receptors, but no downstream messages are sent. It’s like knocking on the door when nobody is home. In spite of all the extra body fat mass, the brain perceives starvation and orders fat storage. The kicker is that you’re also very hungry, and continue to eat more and more.
If you know anyone who just can’t stop eating like Jumbo, as tempting as it may be to instantly judge them, it’s likely not entirely their fault. Many obese people have metabolic systems that are simply broken. You can’t outrun Mother Nature, and if the leptin signaling is messed up, you can only control yourself so much.

What the heck is a snack anyways? How many calories is it outside today?.

Pancreas…Insulin…Body Fat! Ohh My!!.

Micronutrients…Make a Mega Difference!!.

The Forbidden (timing of) Fruit!.

    Okay…so without being hyper-redundant I’d like to edify the truth about fruit.  As I insinuated (w/ the redundancy remark), I’ve written about fruit in the past, yet it’s always one of the first inquisitions people make when the word “diet” is mentioned.  Before I begin, I’d like to clarify upfront…I am NOT against fruit!!!  I’m only against the discordant effects to overall health when an individual’s consumption of fruit is incorrect.  How’s it possible to consume fruit incorrectly??  Glad you asked….
    Fruits are what I personally refer to as “performance carbohydrates” which I differentiate from “cosmetic carbohydrate” in a previous article (performance nutrition vs. cosmetic nutrition).  If after reading this article you learn nothing else, remember this…Fruit MUST be consumed on an EMPTY stomach (at least 2-3hrs after previous meal or before meal 1), otherwise the nutrient value is not only greatly diminished, the fruit becomes rancid and ultimately toxic to the body.  Fruit requires immediate gastric emptying, this is obviously a problem if there is already food in the gut blocking the fruits path directly into the small intestines.  The fragility of fruit, coupled with the highly acidic environment of the stomach are the two glaring factors from a physiological standpoint that illustrate why fruit MUST exit the stomach and enter the intestines (where nutrient uptake occurs anyway) upon consumption.  When considering the notion of fruit becoming rancid in the gut, you can draw a parallel by imagining (better yet do this as an experiment) what happens if you set a glass of orange juice in the sun for the day.  
    Another aspect in the misunderstanding of fruit worth mentioning is that skeletal muscle tissues lack an enzyme to convert fructose (the type of sugar that accounts for approx. 40+ percent of carbohydrates in fruit) into “storable” glycogen, fruit can only be “stored” in the Liver (Hepatic), which unless you’ve been in a carbohydrate depleted state for days or even wks, it’s (the liver) fully loaded, aka NO VACANCY at the inn.  The ideal times to consume fruit in order to maximize all the great vitamins and nutrients they do contain, are upon wake about 30 minutes prior to meal 1, intra-workout or game w/ whey protein, or immediately following the workout or game, also w/ whey protein.  Not to say there aren’t other times of day that fruit may be consumed without problems, I simply find the information more applicable when it’s narrowed down to the most IDEAL times to OPTIMIZE the value fruits provide to the body!….Hopefully this sheds some light on the myths and misunderstandings surrounding one of natures oldest delicacies….Fruit!!  

When’s the last time you walked into the Doctor’s office and asked for a Lymphatic check-up or asked for a Lymph support formula at your local supplement retailer??  I’m gonna go out on a limb and say, probably not very recently…what I really mean is, for 99% of people the answer is NEVER!!  The problem is, how can anyone really be expected to show concerned for, or lose sleep over something they know almost nothing about!?   I’ll be the first to admit, only as of recently have I truly been able to grasp the importance of this intricate system…The Lymphatic System is something you learn about briefly during the Circulatory and/or Immune System chapter’s in Anatomy and Physiology 101, and unless you’re a Pre-Med student that’s the last you really hear of it.  Even then I believe it’s importance is grossly ignored among Medical Professionals as a whole…why??  I’m going to let you in on a little secret…if Doctors truly “cured” their patients, they’d be out of a job before they could say, “scamming ain’t easy.”  Oh, and another thing, if we properly implemented nutrition and exercise programs to prevent health issues…we’d no long need massive amounts of medications from one of the most highly influential “groups” looming over our Country’s government…Pharmaceutical Companies (aka, Big Pharm…follow the money trail people)!  Okay, okay, I digress…my intention for this series on the Lymphatic System has absolutely nothing to do with neither myself nor a political soapbox!
The Lymph System is a network of organs, lymph nodes, lymph ducts, and lymph vessels that produce and transport lymph from tissues to the bloodstream.  The lymph system is a major component of the body’s immune system.  Because this system is rather complex, as well as it is truly unique and interesting, I’ve decided to make this a 3 part series as not to overwhelm (bore) you with information.  As I’ve said countless times before…The better and more complete of an understanding you have of the how’s and why’s in which we all function as humans, the more likely you all are to adhere to some of the ways in which it’s possible to optimize the benefits of lymphatic drainage(which I will certainly delve into) .

Part One: Lymph- (Latin; lympha “water goddess”)
Fact- The human body contains four times more lymph than it does blood!!…That statistic still blows my mind!  I purposely throw it out there to being with in order to stress the mere abundance of lymph…which in turn should spark your interest about a fluid that literally saturates your entire body.  If it doesn’t, I hear ignorance is bliss…continue!!  For those looking to maximize every aspect in which you can ensure a happier, healthier, more fulfilling life, let’s start from the beginning.
Lymph is a clear- to yellowish white fluid made up of white blood cells, especially lymphocytes, the cells that attack bacteria in the blood.  A portion of lymph is comprised of a fluid from the intestines called Chyle; chyle is a milky white fluid containing emulsified fat and other products of digestion, formed from chyle in the small intestines and conveyed by the lacteals and thoracic duct to the veins (Dictionary.com definition).  Lymph in the body is analogous to your cities sewage system…nobody pays much mind to it until stops working properly or gets clogged.
In order to best explain the formation of lymph, let’s backpedal for a moment…Blood supplies nutrients and important metabolites to the cells of a tissue and collects back the waste products they produce, which requires a change of respective constituents between the blood and tissue cells.  However, this exchange is not direct but instead is effected through an intermediary called interstitial fluid or tissue fluid that the blood forms.  Interstitial fluid (ISF) is the fluid that occupies the spaces between the cells and constitutes their immediate environment.  As the blood and the surrounding cells continually add and remove substances from the ISF, it’s composition continually changes (the process of  movement by which these fluids travel throughout the body will be discussed in depth in parts 2 & 3).  ISF forms at the arterial (coming from the heart) end of the capillaries because of the higher pressure of blood compared to veins, and most of it returns to its venous ends and venues; the rest (1%) enters the lymph capillaries as lymph.  Thus, lymph when formed is a watery clear liquid with the same composition as the ISF.  However, as it flows through the lymph nodes it comes in contact with blood, and tends to accumulate more cells (particularly, lymphocytes) and proteins.
Unlike the cardiovascular system, the lymphatic system is not closed and has no central pump.  Lymph transport, therefore, is slow and sporadic.  As lymph circulates, it is pulled into the lymphatic system, an extensive network of vessels and capillaries which is linked to lymph nodes, small nodules which act as filters to trap unwanted substances in the lymph.  Lymph nodes also produce more white blood cells, refreshing the lymph before it’s pumped out of the lymphatic system and back into the body.  Lymph may not be as “showy” as blood, but it is related to an equally complex and ornate system of vessels…This is a good stopping point, by now I hope you have a better understanding about lymph, as well as, a brief introduction to the lymphatic system as a whole, and more importantly a preview or glimpse into part two of this series, where I’ll get into the circulation and re-circulation of lymph and the vessels that make it all possible.
