Happy 2018!

After many dozens of hours putting this together, I'm super excited to announce "Testing Nutritional Status: The Ultimate Cheat Sheet."

Over the course of 2017, many of you followed my podcast series on measuring and managing nutritional status. Some of you absolutely loved it. Some of you found it too technical to follow, or found the episodes too long and dense to share with your friends and family and were excited when I started condensing them into much shorter Chris Masterjohn Lite episodes. At the end of the day, I still am only about 5% through the series, mainly because producing each episode takes me about two weeks of doing nothing else and I need to clear out more time for it.

One of my goals in 2018 is to unleash the complete series.

But this also calls for something else:

  • Could I completely distill the practical, actionable information from all the technical explanations?
  • Could I collect it all into one, easy-to-find place?

One of you wrote to me last year:

Hi Chris, I'd happily pay for a PDF cheat sheet containing all your evidence-based recommendations in one table. I frequently find myself hunting through your transcripts :)

Just a suggestion, keep up the good work.

Man oh man, was he right. Quite often, dozens of hours reviewing the science around a nutrient led me to recommend specific tests that are not in common use, or specific ranges for tests that are commonly used but where the lab's range is far too broad, or just way off.

So I started to put together such a cheat sheet. Lo and behold, I found myself hurting as I tried to find my own practical recommendations in the sprawling 2-hour transcripts. 

🤕

After all this time in the trenches, what I've emerged with... let's just say, ain't no ordinary cheat sheet.

It's the ULTIMATE cheat sheet.

It's is a “cheat sheet” in two ways:

● All of the lab testing required for comprehensive nutritional screening is reduced to a single page, with hyperlinks making ordering any of the tests just one click away.

● In just five pages, I provide full instructions for lab testing, blood pressure, and dietary analysis, as well as an algorithm for quick decisions on what to do next for each marker that may be off.

This “cheat sheet” is ultimate because of what comes next:

● Over 70 pages list the signs and symptoms associated with all the possible nutrient imbalances, the potential causes of nutrient imbalances, and an action plan for correcting each imbalance.

To top it off, it ends with an index of the signs and symptoms of nutrient deficiencies and imbalances. The index has 178 entries, and each entry links directly to the sections of the text where those signs and symptoms are discussed. This makes it incredibly easy to browse through the index for the things that seem most interesting or relevant to you and find exactly what you're looking for without having to read the whole guide.

If you're getting antsy, you can buy it right now, but read on if you'd like to learn more about it.

Three Ways to Use the Cheat Sheet

Let's face it, testing nutritional status can be expensive. In my consulting practice, some of my clients often ask me to find ways to minimize the costs associated with figuring out nutritional problems. Others are able to get practically anything covered by insurance if they use the right labs, and others just want me to find the cream of the crop, the best of the best.

So I've started the cheat sheet by outlining three different ways to use it:

  • In the comprehensive approach, you get the comprehensive lab screening, conduct a dietary analysis and a series of home blood pressure measurements, and collect a list of signs and symptoms that seem relevant from the index.
  • In the time-saving approach, you skip the dietary analysis -- the most time-consuming part -- and only resort to dietary analysis if and when some of your health challenges prove too difficult to resolve without it.
  • In the cost-saving approach, you skip the lab screening, only resorting to running labs when doing so proves necessary to determine the best course of action.

The comprehensive approach is the one that generates the correct strategies the fastest, but if time or finances are constraining, the other two options allow you to make the best of the resources you have at your disposal.

By the way, while practical, this is an entirely educational resource. Please don't try anything in the cheat sheet without consulting your doctor, and please don't ever ignore the advice of your doctor because of anything I've written in the cheat sheet.

This Is a Living Document

Putting this cheat sheet together has been tremendously valuable to me. It required me to do a lot of research, and to collect my thoughts and findings all into one place. I know very well that it's going to be my primary tool for helping myself and others in the years to come. So I want to keep this constantly up-to-date for both myself and for you.

You'll notice that I've called it Version 1.0. Since it's practical in nature, I decided to think of it more like a software program than a book, and went with version over edition.

When you purchase the cheat sheet, I recommend you enter your email address in the shopping cart. That will allow me to email you updates to future editions. If I make small changes to it, I will call the versions 1.1, 1.2, 1.3, and so on, and give you the updates for free. When I make bigger changes, I will release versions 2.0, 3.0, and so on, and give you steep discounts for having purchased version 1.0 early in the life of the guide.

I will also offer you opportunities to give me your feedback on the guide, and I will consider that feedback in the production of updates.

This Is a Practical, Not a Scientific Argument

I've put together a small collection of further reading materials at the end of the guide. If I had thoroughly referenced every statement in the guide, it would be unwieldy, with a sprawling bibliography that rivaled the guide in length. I mean, geez this is a cheat sheet and it's already 78 pages long! Instead, I listed what I consider the best starting places for developing a deeper understanding of the material. One of those resources is my podcast, where I will be doing an episode on each nutrient this year, in full scientific glory.

What that means is that this is not for you if what you are looking for is full explanations of how things work, how I came to each conclusion, and the exact source of each statement pinned clearly to the statement itself. I have plenty of writings of that nature, but this isn't one of them.

This is for you if you want to the practical what-to-do information all distilled into one place. And hundredsof hyperlinks ensuring you never have to scroll, squint your eyes to find things, or make an appointment with Dr. Google.

This Is a Digital Document

The format of the cheat sheet is a PDF. You'll be able to download it immediately after purchase.

You can certainly print it out if you wish, and that might be best if you want to read it straight through. However, please keep in mind that one of the key features is the hundreds of hyperlinks. They bring you to the exact section you want to use when reading the instructions for use. They bring you to the exact paragraph to read when looking things up in the index. They bring you to the exact lab test when looking for a test to order. So, keep the digital version handy if for no other reason than this amazing assortment of links.

An AMAZING Gift for You if You But It This Week

If you buy the cheat sheet this week (by January 9), you can use your proof of purchase at any time to obtain a discount (technically a rebate) on my consultation services:

  • If you purchase a single consultation, you can turn in your proof of purchase and I'll give you $30 back. That's the full value of the cheat sheet. So you can think of this as 10% off the consultation, or getting the cheat sheet completely for FREE.
  • If you purchase a Health and Wellness Package, you can turn in your proof of purchase and I'll give you $100 back. That's a $30 investment to get $100 back, a $70 profit. It's like buying bitcoin!  😉

You don't have to commit to a consultation now. This offer is good for the entire life of my consultation services.

So, the action you need to take this week to be eligible is to purchase the cheat sheet, and to save the email with the download link and receipt as your proof of purchase. The action you can take at any time in the future is to use the proof of purchase for a rebate on my consultation services. This is subject to the availability of my services. If you wait until 2020, I cannot guarantee I will still be offering consultations. If you wait until August, I cannot guarantee you'll get your spot at a convenient time. All I guarantee is that as long as I offer these services, I will honor the rebate.

Even if you decide not to follow up on the rebate, what you get is an amazing resource for the ridiculously cheap "full price" of $30.

Actually, you can pay less than that.

Testing Nutritional Status: The ULTIMATE Cheat Sheet

Happy New Year!

This complex is so rich in biochemical concepts and relevance to health and disease. Having done the dirty work of looking at its organic chemistry mechanisms in the last lesson, here we explore broadly applicable biochemistry principles like energetic coupling and substrate channeling. We look at how thiamin deficiency, oxidative stress, arsenic, and heavy metal poisoning can affect metabolism, and how to recognize markers of these processes in blood or urine. We make the subtle yet critical distinction between oxidative stress and oxidative damage. We look at the role of this complex in Alzheimer’s disease. We then turn to the product of this complex, succinyl CoA, to examine how it provides an entry into the cycle for odd-chain fatty acids and certain amino acids and an exit out of the cycle for the synthesis of heme. In doing so, we look at the roles of vitamins B12 and B6 in these processes, the use of methylmalonic acid to diagnose B12 deficiency, and the ability of B6 deficiency to cause sideroblastic anemia.

This lesson looks at the third step of the citric acid cycle in much more detail, digging into the organic chemistry concepts involved in the conversion of isocitrate to α-ketoglutarate. We dive deep into this because it’s the only way to explain why this step parts ways with most other decarboxylation reactions in that it does not require thiamin (vitamin B1).

This, in turn, provides a basis for understanding why burning carbohydrate for fuel requires twice as much thiamin than burning fat, and why high-fat, low-carbohydrate, ketogenic diets can be used to overcome problems with thiamin deficiency or defects in thiamin-dependent enzymes. We conclude by looking at how this step allows the interconversion of amino acids and citric acid cycle intermediates, the role of vitamin B6 in this process, and the use of enzymes known as transaminases to diagnose B6 deficiency and liver dysfunction.

In this episode, I've extracted from The Ultimate Vitamin K2 Resource the latest developments and elaborated on them for a more in-depth discussion. I begin by telling the story of my 2007 article about Weston Price's activator X, "On the Trail of the Elusive X Factor: Vitamin K2 Revealed." What do I still stand by? What do I see differently? And then I carry us right up through some of the most recent developments as things continue to evolve now.

This episode is brought to you by Kettle and Fire Bone Broth. Use the link kettleandfire.com/chris to get $10 off your first order.

This episode is also brought to you by US Wellness Meats. Head to grasslandbeef.com and enter "Chris" at checkout to get 15% off your order as long as the final price is over $75 and you order fewer than 40 pounds of meat. You can use "Chris" to get the same discount twice.

In this episode, you'll find all the following and more: 0:09:20 Introducing the Ultimate Vitamin K2 Resource; 0:17:50 The story leading up to the 2007 activator X article; 0:25:10 The division between vitamins K1 (phylloquinone) and K2 (menaquinone) is misleadingly simplistic, from both a chemistry perspective and a health perspective. The discovery of menaquinone-4 (MK-4) as a product of animal synthesis hinted at this a half century ago; the more recent discovery of tetrahydromenaquinones, which chemically fit halfway into each category, makes this clear now; that MK-4 has unique effects on gene expression and that short-chain and long-chain MKs have very different tissue distributions make it clear that different forms of "K2" are at least as different from one another as they are from K1; 0:44:50 The content of vitamin K in some foods may be grossly underestimated because tetrahydro-MKs have been ignored; 0:49:50 MK-10 and MK-11 in pork products. Are they from poop? How bioavailable are they? Do they have specific roles in the mitochondria? 1:14:53 I finally weigh in on MK-4 vs. MK-7 with the long-winded rant it has for so long deserved; 1:26:50 The conversion of other K vitamins to MK-4: we now know that it is not only genetically variable, but it is also epigenetically variable, dependent on zinc and magnesium, and inhibited by lipophilic statins used to treat high cholesterol and nitrogenous bisphosphonates used to treat osteoporosis; 1:33:30 MK-4, gene expression, sex hormones and cancer; 1:41:20    Undercarboxylated osteocalcin: more controversial than it needs to be, but a bone-derived hormone that not only promotes leanness, a high metabolic rate, blood sugar stability, insulin sensitivity, and fertility, but we also now know to be necessary for energy utilization during exercise; 1:55:10 What's the optimal dose of vitamin K2 1:59:28 Uncommon side effects of supplementation and a physiological rationale to explain them. 2:06:40 The minimal effective dose to receive the maximum desired effect.

This episode is a recording of the 06/25/2016 Facebook Live event, "Ask Chris Masterjohn, PhD, Anything About Methylation."

Among the questions answered and topics discussed in this episode are the following:

An MTHFR mutation (e.g. C677T) even with normal homocysteine could mean that you are taxing your choline supply and wasting glycine into your urine. Boosting choline and glycine intake could help. What may surprise you is that so could supplementing with creatine!

How to implement the above strategies with natural foods?

Can targeted SAMe supplementation be useful for diagnosing methylation problems?

Choline and fatty liver disease.

Why is my serum B12 soaring through the roof when I haven't even been supplementing?

COMT mutations regulating the balance between mental stability and mental flexibility via dopamine, and whether supplementing with 5-methylfolate could worsen mental problems in people with high COMT activity. Potential relations to obssessive compulsive disorder (OCD) and to post-traumatic stress disorder (PTSD).

How should you get choline if you're allergic to eggs?

With an MTHFR mutation and high liver enzymes, choline would seem to be in order, but should you also rethink your high-fat diet?

All this and more!

In this episode, I discuss some important insights from my Paleo f(x) talk and audience responses to it, including the potential dangers of treating type 1 diabetes with a low-carb diet, the importance of carbs and bodyfat for fertility and sex hormones, and why some people might have a great sex hormone profile on a long-term ketogenic diet despite the importance of insulin's contribution to fertility. I also discuss Headspace meditation, contrast showers, Snapchat, U.S. Wellness Meats liverwurst, Kettle and Fire's upcoming chicken broth and chicken mushroom broth, and my interview with Ben Greenfield.

In this episode, I show you how you can determine whether your genetics are contributing to your sensitivity to blue light, poor sleep, and poor daytime alertness, and what you can do about it. Specifically, I look at the research showing that variations in the gene for the vitamin A-dependent protein melanopsin underlie sensitivity to blue light and teach you how to figure out your own genetics for this protein using a 23andMe account (they don't have a health report for it, but the hack around that is easy).

Is it really true that saturated fatty acids (SFAs) are the "bad fats" and polyunsaturated fatty acids (PUFAs) are the "good fats"? Christopher Ramsden uncovered previously unpublished data undermining the conventional wisdom that we should replace saturated fats with polyunsaturated vegetable oils to lower cholesterol and prevent heart disease. The public health establishment dismissed the findings. Here's my take.
