Seyfried’s Cancer Diet: My Fasting Jump-start To Ketosis

Seyfried’s Cancer Diet: My Fasting Jump-start To Ketosis

Dr. Seyfried’s book, Cancer as a Metabolic Disease, inspired me to attempt a fasting jump-start to ketosis to see how long it takes to achieve his “zone of metabolic management.” Read on to see how it’s going so far! (I’m still alive…) Note: this post was originally published on Aug 1, 2013. It was edited to streamline content and improve graphics, then re-posted in June 2016, therefore some older comments may pertain to content that was removed during revision. Dr. Seyfried’s Ketogenic Diet for Cancer Caution: dietary experiments with fasting and ketosis are best done under medical supervision, particularly if you have a medical condition or take any daily medications. Everyone’s metabolism is different, so results will vary. Please see my post “Is the Ketogenic Diet Safe for Everyone?” After reading Dr. Seyfried’s book,1) I immediately felt sympathy for those of you out there who have cancer now, or who are cancer survivors worried about recurrence—were you hoping for a simple nutritional strategy, such as “eat more broccoli” or “add chia seeds to your morning smoothie?” Had I led you down a road of hope and then left you feeling disheartened when you saw how difficult Dr. Seyfried’s diet appeared to be? Let me try to make it up to you by trying his diet myself while you watch from the comfort of your living room. Seyfried’s Fasting Jump-Start to Ketosis Dr. Seyfried says the fastest way to achieve optimal blood glucose and ketone levels is to begin with a water-only fasting jump-start to ketosis for 3-5 days, and then embark on a low-calorie “ketogenic” diet, aiming for blood sugar levels of 55-65 mg/dL and blood ketone levels of at least 4.0 mM (see article 3 of my cancer series for more details). As a reminder, average blood Continue reading >>

A Summary Of The Tim Ferriss Show: Dr. Attia Interview

A Summary Of The Tim Ferriss Show: Dr. Attia Interview

Our Summary of Dr. Peter Attia's Interview So, here we are, another great podcast from the always informative and entertaining 'Tim Ferriss Show'. This time he will be interviewing Dr. Peter Attia (huge keto-fan), and for the people that do not know who he is, here is a little introduction to him and his work... An ultra-endurance athlete and self-experimenter, Dr. Peter Attia is a medical degree holder from Stanford University. He also has a B.Sc. in mechanical engineering and applied mathematics from Queens University in Ontario, Canada. Attia was also a resident general surgeon from John Hopkins, and addition to that a researcher at the National Cancer Institute under Dr. Steve Rosenberg. His focus was on the role of regulatory T cells in cancer regression, as well as, other immune-based therapies for cancer. Another great thing to point out is that he is the president and co-founder of Nutrition Science Initiative which Tim Ferriss coincidentally advises for. On this particular interview, Attia shares some stories from his life about ultra-endurance and his pre-teenage year's obsession and relation with athleticism and sports. He also talks about the other self-experiments that he delved into and shares his key takeaways from those experiences. And of course, a huge section of this podcast focuses on our favorite topic: ketogenics. Here is the video of the interview down below... Topics that are discussed are down below: Continue reading >>

Hrv And Ketogenic Diet Potential Sports Applications.

Feb 25, 2016 | Uncategorized | 10 comments In our food obsessed society we are constantly bombarded by different trendy diets which often come with outlandish claims of great benefits. The one principle that professionals in the industry do seem to agree on these days is that there is no one diet that fits all. Thinking along the same lines, I have a strong interest in researching different diets and their applications, linking with nutrigenomics and functional testing, to ascertain which diets best fit a specific individual or athlete. With genetic testing now easily accessible and affordable, I was keen to test my own profile in order to help determine my optimal dietary choice. I now know that I have genetic mutations that can predispose me to cardiovascular disease, late onset dementia and metabolic syndrome. The ketogenic diet (KD) has been in clinical use for over 80 years primarily for the treatment of epilepsy1 symptoms, but recent scientific focus has been on its potential application in the field of neurodegenerative diseases and stroke recovery. It seemed a good fit for my genetic profile and hence my curiosity was sparked as to how the KD could be applied for health and in sport performance. That was my challenge to see if I could make it work. Its important to understand the difference between a Low Carb High Fat diet (LCHF) and the Ketogenic Diet. The former could be ketogenic but does not have to be, whereas the latter is in all cases LCHF and normally medium protein (LCMPHF). I am slightly baffled why most articles, papers and blogs fail to mention protein in the KD if protein levels are not taken into consideration this could end ketosis pretty quickly as around of protein can enter gluconeogenesis and protein also could have a pretty strong insulinoge Continue reading >>

How To Lose Fat: Ketosis (keto)

How To Lose Fat: Ketosis (keto)

Are you losing weight or are you losing fat? Are they the same thing? Does it matter? But really, how do I achieve fat loss, QUICKLY? Welcome to the truth about fat loss series. Part I can be found here. Nutritional Ketosis or keto scares the crap out of people for some reason. Well for one it is very often confused and mistaken for Ketoacidosis, which is dangerous for those who are diabetic. TOTALLY DIFFERENT AND ACTUALLY DANGEROUS. A word from one of my favorite men on the planet: “What is diabetic ketoacidosis? When a diabetic (usually a Type I diabetic, but sometimes this occurs in very late-stage, insulin-dependent, Type II diabetics) fails to receive enough insulin, they go into an effective state of starvation. While they may have all the glucose in the world in their bloodstream, without insulin, they can’t get any into their cells. Hence, they are effectively going into starvation. The body does what it would do in anyone – it starts to make ketones out of fat and proteins. Here’s the problem: the diabetic patient in this case can’t produce any insulin, so there is no feedback loop and they continue to produce more and more ketones without stopping.” – Dr. Peter Attia Nutritional Ketosis, on the other hand, is when you put your body into ketosis on purpose by restricting carbs and switching your energy system from relying on sugar to relying on fat. So why else could keto make people so itchy? Maybe because it is so far of a departure from what they have heard for the past 20 years? Eat w(hole in your gut) grains Avoid fat Avoid red meat Get your calories from carbs so you have the energy to lose weight! And here we sit. Still chubby. Still hungry. Feeling pain both physically and emotionally. Extremely frustrated by the fact that we follow the Fo Continue reading >>

8 Reasons The Ketogenic Diet Is The Ultimate Productivity Diet

8 Reasons The Ketogenic Diet Is The Ultimate Productivity Diet

If you’re ambitious and want to do big things with your life there is no better diet than a well-formulated ketogenic diet. Here are 8 reasons why a ketogenic diet is the ultimate diet for productivity. 1. Consistent Energy Inconsistent energy levels were a major reason I first started looking for a better diet. Trying to create consistently is difficult enough without swinging between being distracted by hunger and feeling tired and unmotivated after eating. The good news is evolution solved this problem for humans a long time ago by making fat our primary fuel source, we’ve just forgotten over the last 10,000 years or so[1] (a drop in a pool of evolution). There are many reasons why evolution has shaped us into fat-burning machines but here are two major reasons being ketogenic provides consistent physical and mental energy: a. Giving you quick access to your body’s massive fuel suit (body fat): When you’re in nutritional ketosis your body has quick access to the abundant energy stored in your body fat. A 180lb person with 16% bodyfat has over 100,000 calories of energy attached to their body.[2] What this does is fill in energy gaps between meals allowing you to work in a sweet spot of high energy for hours at a time without being distracted by hunger or bogged down by digestion, it is the perfect state to create. b. Your brain now runs primarily on ketones instead of glucose: This is huge because not only does your brain do better on ketones,[3][4] but ketones are primarily a product of your liver as it burns fat.[5] So what this means is that when you’re ketogenic you have a practically endless supply of energy from fat that your liver then converts into energy on-demand for your brain! 2. Mental Clarity, Acuity, and Focus People are beginning to take not Continue reading >>

The Ketogenic Diet And Type 1 Diabetes: What I Eat

The Ketogenic Diet And Type 1 Diabetes: What I Eat

I recently began writing about the ketogenic diet and type 1 diabetes in an attempt to optimize my blood sugar in relationship to athletic performance. This podcast episode can provide some additional perspective about how I arrived at the ketogenic diet for type 1 diabetes. It started with a low-fat plant-based diet and I have recently changed my approach (dramatically) to a Ketogenic diet (low-carb, high-fat). The results have been remarkable and I feel like this dietary approach is a worthwhile consideration for anyone who is in a position to optimize their diabetes management–or who just wants better energy with no “crashes” throughout the day. In case my standpoint isn’t obvious, let me clarify, there is no should or shouldn’t implied in my writing about this or any other diet. Some people eat pizza. Some people drink diet soda. Some never consume either–or do but always feel guilty. Still others know the drawbacks and act in moderation and feel great about it. My goal is to inform those who are interested in trying something new or just knowing what else is out there–not to persuade those who are happy with an already satisfactory approach. I wrote an eBook compiling my experiments with the ketogenic diet and type 1 diabetes which you can check out here: In my last blog I focused on the comparative results between the two diets, and this blog will hopefully answer the one major question I got–‘what do you eat on a daily basis?’ Not all low-carb diets are Ketogenic, but the Ketogenic diet is low-carb. In the coming weeks I will be sharing more about how my transition to this diet came together as well as mistakes I made along the way. I will also probably put up a post along the lines of “What is a Ketogenic diet?” although that is lower pri Continue reading >>

Paleo Blog - Pack Of Packs

Paleo Blog - Pack Of Packs

Last week I answered Tiffany's emailed question how well I fared on a paleo-ized carb night approach . In a nutshell: For 6 days a week you eat super low carb and on one day with a time window of ca. 8 hours you need to stuff yourself with (if possible) healthy carbs. Initially I did well and then I experienced the carbo downfall equivalent to the Rick Santorum scandal. Yes, I sinned and it was uuuugly. This leads us to Tiffany's question number 2: Which program will help to lean out while still being able to perform in CrossFit? Please be always aware that the following report describes MY approach, tweaked to MY needs and MY metabolic quirks. You will still need to keep tweaking for yourself to make this work for you or it might not even work at all. As I established before, I do well on a low carb high fat diet. Well enough that I produce ketone bodies rather quickly. No cravings for sweets, stable mood and blood sugar level. If it wasn't for all the high intensity stuff I was doing at that time I could just stayed in ketosis, leaning out and not needing any carb refeeds. Alas, for all the fast-paced stuff I was doing at that time, the refeeds were necessary. But as soon as I went on a carb refeed I go through a carb/ sugar addiction relapse. Causing me to submit to carb cravings on low/no carb days. I would kick myself out of ketosis and feel miserable. I wanted to stay in ketosis but I needed to replenish my internal carb storage as well without causing in insulin tsunami in my system. Reminder: Too much insulin in our system inhibits the metabolization of fat as fuel. In very simple terms:Lots of sugar --> lots of insulin --> burn less fat, even gain more fat Although I'm not an active trail runner any more I still have friends in the trail running community. One Continue reading >>

Is The Keto Diet Safe? 10 Myth-busting Arguments For The Safety Of Ketosis

Is The Keto Diet Safe? 10 Myth-busting Arguments For The Safety Of Ketosis

Is ketosis safe? The truth is that we can’t say for certain that it is 100% safe. Humans don’t understand everything under the branch of nutritional science and probably won’t for a very long time. As an individual, the only thing you can do is take a look at the research yourself and form your own conclusion. Personally, through the reading I’ve done and the experience I’ve had with the Keto diet, I’ve formed my own conclusion that ketosis is safe. Could I be wrong? Absolutely. But I could also be right. I’m willing to take that risk in order to follow a diet which could maximize longevity, well being and function. My personal conclusion shouldn’t matter to you though. You need to do your own research and come to your own conclusion. I’ve put together this post to organize all of the issues surrounding the safety of ketosis so that you can make your own decision. In trying to prove something to be safe there are two ways to go about it. Disprove the claims of danger Show evidence which may be correlated with safety This article will dispel the top 10 claims people make in an argument to label ketosis as dangerous. Like I said, the science on ketosis is still quite immature. The following data is not meant to 100% prove or disprove the safety of ketosis. It’s merely the information we have available today which can help us form a nutritional strategy we feel is best for ourselves. I’m not a doctor or a researcher. The following information is material I’ve collected in my attempt to feel confident following a Keto diet indefinitely. Most of it is sourced from doctors or authors although I have also included anecdotal accounts from experiences posted on message boards and Reddit. I know, much of the information here isn’t sourced directly from s Continue reading >>

What Is Keto? The Healthiest Diet You Should Try

What Is Keto? The Healthiest Diet You Should Try

What is Keto? The Healthiest Diet You Should Try More and more people are asking, What is keto ?or What is ketosis ?because so many are losing weight with keto, performing better in the gym, enhancing brain function, boosting energy, and so much more! You wouldnt put diesel in a gasoline engine and expect it to run well, but that is exactly what Americans are doing every day. We fuel our bodies with processed, pre-packaged foods that evolutionary science has proven makes our bodies stop running efficiently. I was guilty of this for much of my life. I remember sitting in the library at age 16 when I triedon my friends jacket and I heard a boy sing, fat girl in a little coat. Following the insult, I restricted fat and worked out constantly. Ironically, this left me fat and frustrated, and I decided to focus on dialing in my nutrition. Id heard about losing weight with keto or ketosis, and after decades of being told by marketing geniuses that fat-free was the way to lose weight, eating real fat was scary for me. Losing weight with keto helped me feel better That first week of keto weight loss was remarkable. On keto, I slept deeper, felt calmer and better than I ever had in my life! I no longer questioned, What is keto? I was living it. Keto helped me feel better. Now, I understand the biochemical reasons why restricting fat is counter-productive to creating optimal health. Growing up, I believed that good-tasting foods made you fat. It was almost too much to imagine that I could thrive and have healthy body compositionwhile enjoying butter, avocados, grass-fed cheeses and meats, and even sugar-free (keto-friendly) cheesecake. But it has been over five years of keto: five years of my body feeling amazing and never feeling deprived! I traded in a lifetime of over-exercisi Continue reading >>

Ill share, it so happens I did an experimental longer training run this morning (which might be of interest and in which I used some small amount of Superstarch) to test and see just how I would feel during the run and how well Id be able to generate/utilise hopefully predominantly ketones during the run. I did 13 miles, 1h59:45, a half marathon personal best time as it turned out, very pleased; estimated 1963 calories burnt. I ran it fasted [meaning I ate no actual breakfast be Continue reading >>

Ketogenic Diet Improves Insulin Sensitivity And Numerous Aging Markers

Ketogenic Diet Improves Insulin Sensitivity And Numerous Aging Markers

A physician conducted a decade-long experiment on the health effects of a ketogenic diet, using himself as the laboratory rat; he experienced improvement in insulin sensitivity, body fat, lipids, blood sugar, and other markers A ketogenic diet requires carbohydrate and protein restriction, with 50 to 80 percent of calories coming from fats; this forces your body to shift toward using ketones as its primary fuel source, instead of glucose Although your brain is more dependent on glucose than your heart, your liver can produce a ketone-like compound that your brain can efficiently use for energy Scientists extended the lifespan of mice by 20 percent by suppressing the activity of just one gene that helps control metabolism and energy balance; this is further evidence that longevity is tied to insulin signaling The best way to jumpstart your fat-burning/ketone-producing engine is by drastically reducing your consumption of sugar and grains, fasting intermittently, and maintaining a consistent exercise routine By Dr. Mercola We are just beginning to understand the biological intricacies of aging. A growing body of research is challenging the belief that aging is beyond your control, prompting scientists to begin thinking about ways we can slow our aging clocks to a slow crawl. Although this is a relatively new branch of science, there are some factors that appear to be key in controlling how quickly you age. One major factor seems to be insulin signaling and the metabolic "engines" you have running day to day, which are largely controlled by the foods you eat. In the first featured video, Dr. Peter Attia discusses how a ketogenic diet can optimize your metabolism. But before I discuss the specifics of this, I want to tell you about a remarkable mouse study, presented in the Continue reading >>

Is Low Carb The Best Way To Eat?

Is Low Carb The Best Way To Eat?

My thoughts on Low Carb and Paleo Episode 3: A New Hope Yes, I know A New Hope was episode 4, but I could not think of a catchy but Germaine line that sounds like Revenge of The Sith, and this thing was only supposed to be two parts as it is! Call it artistic license I guess. If you missed part 1 and part 2 make sure to check those out. I want to look at some of the specific claims, misconceptions, and actual benefits surrounding low carb. I think Ive said this a few times now, but Ill make the point again: I see many important uses for LC/ketogenic diets. I had more than a few comment that Keto was the only way they could control their autoimmune condition. Bully for them, and this is precisely why we need to not only research LC, but be willing to pull it out of the tool box and give it a whirl. While we are doing that though, lets remember we have other tools, and situations in which LC simply is not going to be appropriate. No need to get poopy pants over all that, better to just learn and grow. Is ketosis the natural state for humans? I must throw myself under the bus on this one. I do not think itd be tough to do some google searching and find some circa 2003-2004 era comments on my part stating ketosis was THE natural metabolic state for humans. I based this off the observation that ketosis was effective for a host of ills and might hold some promise for an extended lifespan (Ill get to that mistake in a bit). Something I had not considered in all this was that the efficacy of ketosis had nothing to do with it being the natural metabolic state for humans, and everything to do with limiting the ingestion of too many calories and reducing pro-inflammatory gut irritants. When I started looking at the animal models of ketosis, it was interesting that we were not see Continue reading >>

The Peter Attia Approach To Dieting For Endurance Athletes (part One)

The Peter Attia Approach To Dieting For Endurance Athletes (part One)

The Peter Attia Approach to Dieting for Endurance Athletes (Part One) Ill start by declaring my bias from the outset. Im a fan of Dr. Peter Attia . So I was flattered when asked by TrainingPeaks to write this blog post, and even more honored when Peter granted permission for me to take on the task. However, please note that while Peters fine with me trying to tackle the topic, it does not imply his endorsement of the approaches in this article. Herein begins a two-part blog post to try to do the topic of low carbohydrate/high fat dieting justice. I first stumbled across Dr. Attias work during my own experimentation with lowering carbohydrates in my diet and when trying to understand the positive effects I observed it having on my blood pressure, fat oxidation and endurance performance. Like Stephen Phinney, Jeff Volek, and Tim Noakes, Peter is a pioneer in this area, and has an extensive website that details his work at EatingAcademy.com. Peter is a physician, a researcher, former ultra-endurance swimmer and cycling time trialist who continues to forge new ground in the areas of health and longevity. He has a super interesting background. A fellow Canadian, Peter took a different road toward developing his knowledge of exercise science than many of us in the field typically do. Peter is a self-confessed near high school dropout who was about to dedicate his life to the sport of boxing when a high school teacher inspired him to pursue undergraduate degrees in mathematics and engineering. Topping his class, he moved to Stanford medicine to complete his M.D., before becoming asurgical residentat The Johns Hopkins Hospital. Over time, Peter grew frustrated with certain challenges within the medical system, and eventually changed course to begin working privately. He shares Continue reading >>
