This is a collection of useful whey information you can use to make smart choices when purchasing whey and learn what makes whey a unique protein source, both for active people/athlete, as well as health minded individuals.
Whey protein is one of the most popular protein supplements sold. It’s used by athletes of all kinds and those looking to benefit from this protein, that has literally been used as a medicinal food for thousands of years. However, much confusion over whey abounds. What types are best? Isolates or concentrates? Grass fed organic whey best? Can it help with weight loss? What about cancer and immunity? Where does whey come from and what about compounds within whey (such as lactoferrin) that have their own potential benefits?
Fifty Shades Of Whey will clear up the confusion – using objective science based information vs. marketing and hyperbole so common – to help users of this food supplement make smart decisions on whey proteins.

This is a topic so large it could take stacks of text books (and it does!) and many semesters in college and years of research afterward, so an exhaustive review is both beyond the scope of this article and my brain!
There’s a few key areas however I plan to address in this article people will find helpful to making smart decisions the over hyped ads for protein, amino acids, and peptides don’t cover. For the most part, I recommend whole protein sources, such as whey, eggs, lean meats, fish etc. in terms of dietary protein* intakes, but some individual amino acids can be of benefit in specific applications. Those applications may be sports performance related, general health, or medical, but I’m getting ahead of myself.
Back In The Day…
Back in the day when I was taking my first nutrition courses and reading what research existed - right after the Pleistocene era – the mantra of nutrition was that digested proteins were broken down into individual amino acids during digestion and absorbed, and that was that. As with virtually all overly simplified models generated from the early research examining human nutrition and physiology, it was wrong. To this day however, there are still those who believe it, but I digress. However, most know that ingested proteins are broken down primarily into small peptides and individual amino acids. The fact is, to this day, human digestion, absorption, and utilization of nutrients we ingest is still being elucidated with more discoveries being made than most people realize or appreciate. It’s amazing to me however the number of people – some educated enough in the sciences to know better – who think digestion, absorption, and utilization of the food we eat can be summarized as “it get’s dumped into the acid in your stomach, then absorbed via voodoo, the end.” Human digestion, absorption, and utilization of the nutrients we ingest, is an incredibly complex process, that as previously mentioned, still being elucidated. If you want to get a glimpse of how complex, the Encyclopedia Britannica site has a nice write up on that, and remember: digestion, absorption, and utilization of protein is but one very small aspect of it.
As mentioned previously, there are benefits and potentially unique effects to using individual amino acids, but studies indicate peptides are better absorbed and or utilized than individual amino acids. What that suggests is, even if the goal is to derive benefits from a singe amino acid (e.g., Leucine, Glutamine, etc.), it’s likely best to get it in peptide form. For example, instead of taking L-leucine alone as the free amino acid, to increase intakes of L-leucine, ingesting a leucine rich peptide is likely to be the superior approach. The science and understanding of the value of peptides in human nutrition, be it for health, performance, increased muscle mass, etc., is an evolving area of research yielding useful findings, and still in it’s early stages in fact. Because this is such a wide-open and extensive topic, I’m going to stay focused on a few key issues, such as the value of using individual amino acids or “free” amino acids vs. peptides even if the goal is to increase levels of a specific amino acid.
Yes, some people are non responders to exercise while some are “super” responders. A recent study looked at 1000 people put on the same exercise program. The results, which I discuss in this vid, may shock you!
This is a very interesting area of research. We all know people who do the same exercise as we do, yet either don’t seem to benefit much, or benefit far more than we might expect. Having trained hundreds at this point and or communicated with many thousands more, I have seen that first hand.
Important Information For Those on Thryoid meds and or SSRI’s
Considering how many people are on thyroid meds and or SSRI’s, it’s surprising – especially in the case of thyroid medications – how much confusion exists in the medical community on how best to treat people with hypothyroid.
I find many people feel they are often in some sort of battle between themselves and their doctor as to what doses, types, etc of thyroid meds they need.
A book called “Thyroid Disorders” written by a Dr Gilbert Daniels, listed as Co- Director of the Thyroid Clinic at Mass General Hospital makes for a good reference guide. The book was published in 2006, so I am assuming he’s still there. The book is written for physicians, specifically for GPs/family physicians vs. specialists. Most of the information would be basic rehash for the people here that have already done a lot of research on the topic, and most of what he recommends is in line with the standard recommendations. Some of Dr. Daniels comments below on T4/T3 combination therapy was supported by recent studies that found people on a combo therapy much prefer it over a T4 mono therapy.
“The human body is an infinitely complex, but wholly logical system” – Will Brink
Back in the day I wrote the first article on the value of omega-3 fatty acids (via fax oil) for health and fat loss in the major bodybuilding publications. In fact, my first article on the value of flax oil – a source of the Omega 3 lipid LNA – was rejected because the very idea of intentionally adding fat to lose fat and improve health was such a foreign concept at that time. Yes, we are talking pre Internet here! Lucky for me, another magazine – MuscleMag International – ran the article, and the rest is history. It’s safe to say I have been researching and writing about Essential fatty acids (EFA’s), the value of omega-3 fats, the importance of balancing fatty acid intakes, and so forth, for a extensive amount of time. I am also partially to blame for the overly simplistic view of these fatty acids that followed and hope to atone for that with this article.
Much of what we understood at that time, and is still being pushed to this day by some, was an overly simple and generalized view of the essential fatty acids (EFA’s) and their effects on human physiology. As time progressed, and additional research was published, the picture has become much more refined and accurate.
The old paradigm could be essentially summarized as “Omega-3 good, Omega-6 bad” and that was about it. Other than a few who have really taken the time to research the topic, a position that remains to this day. Per usual, such entrenched views tend to change very slowly.
How did that start? Early research found the Standard American diet (SAD) provides excessive intakes of omega-6 lipids and minimal omega-3 lipids which resulted in an elevated omega-6/omega-3 ratio. As science writer Monica Mollica put it so accurately in her recent article on BrinkZone.com, “In turn, an elevated omega-6/omega-3 ratio has been linked to a number of common chronic diseases, notably cardiovascular diseases, inflammatory diseases, cancer, and certain psychiatric diseases such as depression. The omega-6 fatty acid that has been vilified and blamed to give rise to these detrimental health outcomes is arachidonic acid (ARA).” Hence, we ended up with an “Omega-3 good, Omega-6 bad” model that attributed most of the negatives to ARA, with advice people should avoid ARA. Those concerned with their health increased their intake of omega-3 fats via fish, flax, supplements, etc., and reduced their intake of omega-6, to improve their 03/06 ratios.
All well and good, but it’s just not that simple as life rarely is, much less human biology. As Candice Pert Ph.D., discoverer of the opiate receptor said “Whenever something does not fit the reigning paradigm, the initial response in the mainstream is to deny the facts.” Such is the case with the “Omega-3 good, Omega-6 bad” model that some cling to in spite of the ever mounting data showing it to be an outdated model not supported by the modern data.
In prior posts, I have discussed my hypothesis that growth hormone and related growth factors, as a possible therapy for connective tissue/joint degeneration in active populations. The study below finds testosterone therapy (TRT ) appears highly valuable treatment in SCI; to prevent the loss of skeletal muscle post SCI. These results do not surprise me in the least and why this is not a common therapy for people with SCI is a tragedy in my view. If you, or someone you know, has suffered a SCI, I highly recommend you send this info to your/their doctor and pursue this as a possible option. It’s important to note that testosterone deficiency is common after SCI, and according to the U.S. Department of Veterans Affairs SCI unit:
“These findings confirm both a substantial population of men with SCI and with testosterone deficiency, and a significant association between testosterone level and severity of SCI. Measuring serum total testosterone levels should be included in standard screenings for patients with SCI…”
I can say, a very common report of those who go on TRT is a big reduction in general aches and pains in my experience, and again, it makes perfect sense to me. The future treatment of SCI will be the of use various growth factors and other modalities (such as stem cell therapy) to re grow/re connect the spinal cord. That technology is much closer than people realize, but it seems the med/sci community very slow to pursue this area as quickly as they should. Obviously, this approach could be used to repair damaged nerves and other tissues far less challenging than repairing a severely damage or severed spinal cord.
Useful summary info from this study Effects of testosterone replacement therapy on skeletal muscle after spinal cord injury:
“The most important finding of this study was that TRT ameliorated the decrease in fiber CSA resulting from SCI. TRT also attenuated the slow to fast fiber type shift as well as the decrease in oxidative enzyme activity. To our knowledge, this is the first study to investigate the potential of TRT to prevent atrophy in SCI. TRT in aging sarcopenia and in other diseases with muscle wasting (for example, AIDS) results in favorable effects on bone, muscle size and strength in both low-average and hypogonadal men.19 Increases in muscle CSA were equal, if not greater in TRT only groups than in exercise groups without TRT.20 These data and ours for SCI both demonstrate a positive effect of TRT on muscle size without traditional overload…”
Someone once said “there’s no sunshine without coffee.” I tend to agree. However, there’s a great deal more to understand regarding the benefits of caffeine – the central nervous system stimulant most people associate with coffee – and its effects on mental acuity, performance, etc. In this article I’m going to cover what people really need to know about this topic, and suggest a way to get the most bang for your money when it comes to this highly popular beverage and supplement.
Caffeine – a compound in the methylxanthine family – has its effects through various mechanisms on the central nervous system, and to be honest, I doubt those mechanisms are of great interest to most readers, so I won’t bother with an extensive discussion on it here. Suffice to say, caffeine positively impacts memory, performance, endurance, coordination and increases arousal, vigilance, while reducing fatigue, to name a few effects. Anyone who has used straight caffeine knows the stuff works, which is why the military, for example, adds it to gum as well as other things like bars and such. We all know the “energy drink/shot” category is all the rage these days even outside the gym setting. Although caffeine is not for everyone to be sure, it’s amazingly non-toxic. OK, so users of caffeine either know all this, or have at least experienced it, and don’t need much convincing it’s effective stuff for its intended uses. Let’s move into the more interesting info of this article, shall we?
Does Your Mind Stop You From Losing Weight?
It’s interesting to note; the single most important factor to not just getting the weight off, but keeping it off, is between our ears. That is, how people approach the issue, psychologically speaking, is an essential component of success. And yet, 8 zillion weight loss books and programs out there, and at best, this aspect of weight loss gets lip service only.
Many diet programs out there don’t address the psychological aspect of why people fail to be successful with long-term weight loss. However, quite a few studies exist that have looked at just that. In many respects, the psychological aspect is the most important for long-term weight loss, and probably the most underappreciated component.
Book Review: The Skinny On Diet Supplements
By Rick Silverman M.D.
If you’re the kind of person who likes to have the inside scoop, the real deal, the down and dirty on any given issue, then Will Brink’s book, “The Skinny on Diet Supplements,” should be on your required reading list for nutritional supplement information. This book is an encyclopedia of dietary
supplements and their role in weight loss, looking at each item in an in-depth and organized way.
Each chapter focuses on a single supplement, cites what it’s supposed to do, and provides details of the science behind the product, including some dissection of that science. The next section looks at the “real world” chatter about the supplement, and that’s followed by the best feature of the book, Will Brink’s recommendations. This last feature is my favorite section in each chapter, because Will is not shy about saying what works and what doesn’t work. He isn’t beholden to any particular supplement or supplement company, so it doesn’t feel like you’re being sold a bill of goods. Rather, he cuts through the falsehoods put forth by the supplement industry, and where evidence supports the use of a product and that product has proven real world results, he tells you so. Where evidence or the real world comes up short, he tells you that.
