KetoFasting: The Dark Side of Fasting & Ketosis (+How To Use Cyclic Ketosis To Fix The Issues)
Boundless Life23 Mar 2019

KetoFasting: The Dark Side of Fasting & Ketosis (+How To Use Cyclic Ketosis To Fix The Issues)

From Dr. Joseph Mercola, my friend, multiple-time podcast guest, a guy who thinks way outside-the-box and seems to always be discovering some new cutting-edge way to enhance human health and longevity, and one of the world's foremost authorities on alternative health has just written a guide to using the principles of ketogenic eating, meal planning, and timing to treat disease, promote weight loss, and optimize health.

The new book is called "KetoFast: Rejuvenate Your Health with a Step-by-Step Guide to Timing Your Ketogenic Meals". In the book, he explores the profound health benefits that result when ketogenic living and well-planned fasting are combined. Topics include:

-How our food is making us sick and what we can do about it...

-The physiology and mechanisms of fasting, including stem cell activation...

-How the cyclical ketogenic diet--with fasting included--differs from the conventional keto diet...

-How fasting works and how safe it is for you...

-How regular one-day fasts support fat burning and detoxification while minimizing hunger and side effects...

-How to monitor your progress with lab tests...

-And much more...

During our discussion, you'll discover: -The fascinating history of fasting among different religions and cultures...8:25
  • Dr. Mercola's book was originally written to learn to optimize multiple day water fasting
  • Most religions integrate fasting into their practice (speaks to its efficacy throughout history)
  • It's one of the best ways to express care for your spirit, especially when combined with meditation, gratitude, solitude, etc.
  • Therapeutic fasting:
    • Calorie restriction to activate metabolic processes to catalyze the healing process
    • Fasting didn't become popular in the U.S. until the 1800's with the natural hygiene movement
    • Became more popular when Herbert Shelton popularized it in 1911
  • TrueNorth Health Center
-Autophagy, and why Dr. Mercola thinks of a fast as a "free stem cell transplant"...16:45
  • Different varieties of fasting:
    • Intermittent (the foundation)
    • You need more than intermittent to get the max effect of autophagy
    • Fasting mimicking diet, water diet
    • Hybrid of the two, minimize the harmful effects
  • Autophagy:
    • 3 types
      • Micro
      • Macro
      • Chaperone mediated
    • You activate autophagy with the keto fast
    • Dr. Mercola does not recommend a long-term water fast
    • Free stem cell transplant is what happens during the regeneration phase, after the autophagy phase
    • The magic happens during the refeed and strength rebuilding; similar to a growth hormone injection
    • Do a 42 hour fast, in which you eat 300-500 calories 2x per week
-How fasting affects intestinal stem cell function...24:20
  • Extended fasting helps reduce gut permeability by stimulating brain/gut pathways
  • Consider fasting before other treatments or supplements for repairing the gut
    • Certain supplements will inhibit autophagy: colostrum, B12
  • AMP-k and mTOR
    • It's your friend; The higher the better
    • A nutrient sensor
    • Puts your body in "repair mode"
    • See Saw: AMP-k up, mTOR down, vice versa
-What nutrients you need to optimize autophagy...34:08 -How ketones protect the brain excess hydrogen peroxide...46:00
  • Fats and carbs are fuel sources; broken down by enzymes
  • Oxygen receives electrons from the food you're digesting in the form of hydrogen (which is converted to water)
  • Most people are metabolically inflexible; can't burn much fat for fuel
  • Ketones increase Nicotinamide adenine dinucleotide phosphate (nADPH)
-Why Dr. Mercola changed his mind about the power of water fasting as a metabolic intervention...50:55
  • We in the 21st century are exposed to chemical and industrial toxins not historically known to humans
  • Toxins are stored in our fat
  • When you fast, you release these toxins
  • Cause unpleasant side effects and symptoms
  • 2 phases:
    • Convert fat soluble to water soluble (not a problem)
    • Attach molecules to the toxin
  • You need frequent refeeds to fuel the process of eliminating the toxins and enhancing detox pathways
  • A keto fast (42 hours, 300-500 calories) 2x/week is far more powerful than an occasional multi-day water fast or even fast mimicking diet
-What Dr. Mercola views as the "dark side of fasting"...55:00
  • Detoxification impairment
  • Compliance: people just won't do it
  • How Dr. Mercola recommends Ben improve his own fasting strategy:
    • Ben takes essential amino acids for protein during extended fasts
    • Don't eat meat protein (branch chain amino acids)
    • Take collagen protein
  • Drawbacks to long-term ketosis
    • Requires significant calorie restriction
    • Women can develop thyroid impairment
    • You simply weren't designed to do it
    • Fasting primes your body for improvement; the real magic happens in the refeeds
-What is "keto fasting," and how cyclical ketosis addresses the above issues...1:00:13
  • You must be metabolically flexible
    • Eat in a 4-6 hour window per day for 4 weeks
  • Branch chain aminos: lucine, isoleucine, valine
    • Eat these on the refeed, not during the keto fast
    • Don't activate mTor along with autophagy
  • Cyclical approach:
    • Keto fast 2x/week
    • Every day intermittent fast
  • Strategies to deal with hunger or appetite cravings:
    • Vast majority of metabolically flexible people won't feel hungry
    • Coconut oil, MCT oil, aloe gel
    • Nicotine gum and sparkling water
-How sauna use supports a fasting protocol, an ideal sauna setup, and sauna do's and don't's...1:07:45 -And much more! Resources from this episode:

Audio Question from Eric: He wants to get back to race weight (is currently 30-35lbs over what he would like to weigh). He has some racing goals that he will have to push himself to reach. Should he try to lose weight before the race (in the early season) or just train hard and lose the weight at the same time? ~ In my response, I recommend www.Tri-Ripped.com Chris says: Most of your topics seam to address cardio and diet. Can you do a show on soft tissue injuries and flexibility. My big limiters, that I can't seem to fix, are stiffness in my ankle and lower back. ~ In my response, I mention Capraflex. Tim asks: I am training for some ultra marathons in the 50 to 100 mile range. During my training, I am experimenting with different nutrition sources to find what works well for me. In the past, foods that seem to work perfectly for a 2 to 3 hour run can wreak havoc on my G.I. system during a longer run or race. Given the same effort level in training & racing, what changes occur in the stomach to create this problem? Also, is there a certain length of time that I can run to fully test a nutrition source without having to run the full race distance? Josh asks: I know you've said before that you typically only consume fructose after a workout. Recently I came across some literature saying not to eat fruit after a workout because, "Consuming fructose will increase production of somatostatin, which then inhibits the production of human growth hormone (HGH, also known as 'the fitness hormone')." If true, that's a fairly big deal. Just wondering what your thoughts are. Jonas says: My brother turned me onto your site. He is a marathon runner, and I am a crossfitter/boxer. He has convinced me to live by your food pyramid and make some changes to my life. A lot of these changes are forcing me to toss some of my supplements. Where I am struggling is a pre-workout supplement that helps me lift more and not get fatigued. I have used Jack3d and Other products similar in the past. Can you suggest one that is better to use that has no neurotoxins, artificial colors, and other bad stuff? ~ In my response, I recommend the strength section at http://goo.gl/Zu02D Osa asks: Is it possible to fast your way into Ketosis and how long does it take? Also do you have any tips I can use to stay in shape or at least maintain a healthy weight with no exercise for a couple weeks? I had oral surgery to remove all four of my wisdom teeth this morning. I was advised by the doctor that the day before my appointment that I should stop eating or drinking before midnight. I stopped eating and drinking at 10:00pm and my appointment was at 9:30am the next day. I did not start feeling hungry until around 6:00pm today, so I fasted 20hrs in total and was not experiencing ravenous hunger. I also noticed when I was breathing through my nose I could start smelling some gas from my breath, which is a sign I may have fasted myself into Ketosis. The Oral Surgery to remove my four wisdom teeth has drastically changed my diet and made me inactive for a couple weeks. I can only eat light meals and have been advised not to eat meat. khoo asks: I am participating in a multi staged ultra marathon over 3 days, 42k on the first day, 40k on the second day and 18k on the last day. The challenge is that it will be at the outer Mongolia, border of Russia. the only thing the race organizer will provide is a tent and hot water. All participants will need to bring their own fuel, food and recovery mix. In my plan, I will bring freeze dry meals, pork/beef jerky, trail mix (nuts and dried fruits), dark chocolate, endurox R4, hammer recovery drink, GU gels and roctane. Any recommendation on what else to bring? ~ In my response I recommend Pemmican, Cocochia bars, and Supergreens. Adam asks:
 Can you further explain the link between growth hormone and testosterone. I am 24 and have been taking about 3g of GABA before bed to improve sleep by increasing growth hormone. I do not want to mess with my testosterone and I also have skin that easily breaks out and increased testosterone will only be making that worse. Sarah asks:I want to know if energy supplements are safe for you? I run about 45-50 miles a week and do strength training 3 days a weeks. A trainer at the gym I go to recommended Lean EFX Thermogenic 45cpLean EFX Energy Enhancing Pills from Fahrenheit Nutrition. The reviews online are mixed. Also, recently in the news (recommended by Dr. OZ) - Raspberry Ketones - are these safe? If so which brand do you recommend?

Audio Question from Chuck: When you follow a high fat diet and go for a really long bike ride (3 to 6 hours) what do you use to fuel during these rides? Audio Question from Chris: Recently complete an Olympic Triathlon and is signed up for another one 4 weeks later (now 3 weeks away). He had a good rest week and feels like he will be ready but would like some suggestions for training and tapering. ~ In my response, I mention the article "How To Bounce Back From Ironman With Lightning Speed". Osa asks: Is the Low-Carb diet actually bad for you in the longterm? I am just concerned because there is a new study spreading around the web that says that low-carb diets significantly raise the risk of heart disease. What do you think about the article Atkins diet 'raises risk of heart disease' because of a surge in cholesterol levels? ~ In my response to Osa, I mention the Superhuman Food Pyramid. Frances says: I have been suffering from adult acne since I got pregnant with my 1 year old. I take a good probiotic, fish oil and eat what I consider to be a very healthy --whole food-- diet. I have celiac disease and adhere to a gluten free diet. I have also eliminated dairy, but to no avail. I am currently training for a 1/2 marathon and about to be in training for the NYC full marathon and wonder what kind of hormonal changes occur as a result of endurance training. As someone who prides myself on a healthy lifestyle it pains me to have acne as it seems like it must be something I am doing wrong! Have you seen any studies on the skin-diet-hormone connection? ~ In my response to Frances, I mention another podcast we did on Acne. Rebecca says: I've been a distance swimmer for years, and a distance runner for almost a year, and from these experiences, I know that when I have PMS / the first few days of my period, I'm just wiped out and achy. Sadly the race falls on what should be the first day of my period. I can't alter this using birth control, so I just have to race through it. Any advice to make it more comfortable? ~ In my response to Rebecca, I mention making sure to control estrogen levels, and this podcast we did on estrogen dominance. John asks: Ambien/Zolpidem: what's your take on the benefits of 7-8 hours of solid sleep before a 100 miler (or any other early morning 5+ hour event) if it means popping a pill? My alternative is 3ish hours of sleep and a very painful morning. I've tried it both ways: last year I ran a 100 mile PR after a great night of "aided" sleep, while the year before - sans drugs - I struggled to stay awake through the hours leading up to the second sunrise. Do you have any other tricks or tips for ensuring a good night's sleep and conquering pre-race jitters? I've read that the amount of sleep the night before race morning is less important than the preceding days'. Is Ambien either banned or dangerous? ~ In my response to John, I reference my sleep recommendations.  I also recommend www.darksideofsleepingpills.com Keerthi asks: I've heard contradicting things about Yohimbe HCL for fat loss all over the internet and that it doesn't work if there is any insulin response. So, it would be great if you could give your thoughts on this supplement and the right time, and at what dosage, to take it. Steve says: I recently discovered the exercise called "burpees" - wow! I did two sets of 15 reps with about a minute rest in between and was gassed! I like to run and typically run 20-25 miles a week and enter a handful of 5K, 10K and half marathons a year. Ideally I lift weights about 2x - sometimes 3x a week. My question is how and when to incorporate burpees into my training without messing up my running training ? Erin asks: I am a 25 year old female, 5'3'', ~120lbs with a naturally very low body fat percentage. Ever since I was young, my body has always carried a lot of muscle, especially in my upper body (shoulders, biceps, triceps). While I do love working out and have participated in a variety of different workout styles and intensities (yoga/pilates, crossfit, endurance training, etc), I always have the same bulkiness to my upper body and I do not like it! Can you offer me any advice to get rid of the muscle but still maintain a good fitness level? As of lately, I have been trying to solely do cardiovascular training (swim, bike, run) and eat a pretty low protein diet. Do you think I should try a hypocaloric diet? ~ In my response to Erin, I mention GetFitGuy.com. Don says: My question is about fatigue. Is fatigue from lack of sleep different from fatigue after a workout. As a truck driver, my sleep patterns are erratic so that lack of sleep is a chronic problem. Is the efficacy of a workout affected by this type of fatigue. Further to this, and I know you're not a fan of energy drinks, but I find that a Red Bull can make an otherwise difficult workout more do-able. Will this affect the efficacy of the workout. Andrea asks: I'm a personal trainer and recently worked with a client who has been on prescription pain meds long term due to a back surgery. He recently got tested by his doctor and was told that he has low testosterone due to the long term vicodin use. The doc is supplementing his testosterone, and the client is now losing weight and feeling less fatigued and depressed. I was shocked to learn that prescription pain meds could affect his hormone levels to such a degree. Have you ever heard of this? And if so, what kind of nutrient deficiencies or hormone problems could long term pain medication use create in female athletes? ~ In my response to Andrea, I mention cold thermogenesis and Phenocane.
