Exercise

2016 update

Read Time 8 minutes

Yes, I know, I haven’t written a blog post since ‘nam. Unfortunately (for anyone looking to read a new one) I’m not about to start now. But…I do have two things to offer in the place of treatises on cholesterol (yes, I know, I didn’t finish the Straight Dope series), insulin resistance, hypothyroidism, and a dozen other topics (not including “what I eat, circa Q12016”): first, a series of updates (most of you will want to skip this section if you’re only here for the hardcore science talk); second, a few recent podcasts I’ve done.

Update 1: Work, then

I am no longer at NuSI. I left NuSI at the end of 2015 after four great, albeit very challenging, years. The work we started is still going on and in the following years I look forward to seeing the published research as it becomes available to the public (which I am now a part of).

Update 2: Work, now

Today I am working Peter-part-time (30-35 hours/week) on my medical practice, which is located in San Diego and NYC. It’s a very small practice and sort of referral only. It is not a “ketogenic” practice whatever that means (though people seem to ask me that). The focus is longevity and healthspan, for which nutrition is but one of eight components. I love this work more than I can describe, but I have no plans to scale this practice. For now I’m more content to build a few Ferrari’s a year than a thousand Toyota’s. Nothing against scalable, mass-produced reliable cars, but I’m obsessed with perfection, and I can’t perfect much more than a small handful of patients at a time.

The other half of my time is spent working on things I’m not ready to talk about publicly yet, but they are very much related to my interests expressed in the practice.

Lastly, I am (slowly) working on turning my 10,000 word longevity manifesto (circa 2014) into a book. No, I’m not willing to share the manifesto, but I hope it will be worth the wait when/if the book ever comes out.

Update 3: Exercise

Because I get asked a lot on the blog and through social medial…here goes:

I hung up the bike in January 2015 (from a competitive standpoint). I simply could not travel 140 days a year (which I did last year), work 60-80 hours/week, spend time with my family, and be a quasi-serious wannabe time-trialist. And if I could, I don’t think I wanted to. So the past year marks a first, since the age of 13—it’s the first year I have not competed in something. It felt horrible for a few months, but I’m at peace with the fact that I can’t FTP at more than 4 watts/kg and probably never will again (especially since I think it was actually shortening my lifespan, not lengthening it). I will ride socially a couple of times per month, and find the experience fun and humbling simultaneously. I’m swimming Master’s zero to three times per week, depending on my travel (on my two weeks/month in NYC, it’s zero; in SD it’s 2-3). To fill the some of the endorphin void I’ve take up bootcamps—Barry’s in NYC and OTF in San Diego. Lastly, I’ve re-discovered my obsession with heavy squats and deadlifts. So total exercise volume is low-ish by my historical standards varying between 8 and 12 hours/week with nothing constituting “training” except for squats and deadlifts.

Because I know someone will ask, here is my favorite squat/deadlift set: after a thorough warmup of 7-10 sets ascending in weight, the main set is 5 sets of 5 reps, followed by 4 sets of 10 reps, following by 3 sets of 20 reps. Pat Jak introduced me to this set. Another cool variation, which I did yesterday, is ascending sets of 5 reps until failure (i.e., keep increasing the weight until you can’t get 5 reps), then dropping down to a “test” weight (I use 315 on deadlift and 275 on squat) and going to failure. Then, drop to a second, lighter “test” weight (I used 275 on deadlift and 225 on squat) and go to failure once more. Failure occurs when form breaks, not when you fall under the bar and the goal is increase the reps of those test sets each week.

I don’t possess the vocabulary to explain what this does to my glycogen reserves.

Do not—repeat—do not do this if you don’t know how to squat and deadlift perfectly. If you’re looking for an education, I can’t recommend Mark Rippetoe enough. His book, Starting Strength, is a bible for anyone who wants to correctly lift heavy weights. I also plan to take his 3-day course for a little tune up. I’ve been doing these exercises since I was about 15, and was fortunate to be coached by wonderful people, but you can’t be too perfect in these movements.

Update 4: Displacement

People who meet me often assume I’m uber-competitive. Actually, I’m not and I don’t think I ever have been. I’m obsessed with mastery, though, yet I consider that very inward. Swimming and cycling were amazing ways to scratch that itch and so was surgery, mathematics, and virtually everything I’ve ever done. So in another effort to fill that mastery void, now that I’m no longer training hard enough to master anything, I’ve been putting more time into another passion—auto racing.

I could write three or four blogposts about this obsession! Last year I managed 9 full days on the track (Laguna Seca and Buttonwillow, above in spec E30) and this year will probably be the same, but the game-changer is my simulator. Using iracing software and a professional simulator built my Mike Wagner (see pic, below, including my shrine to Ayrton Senna) which is the most realistic sim out there, I can actually spend 60-90 minutes per week in the sim and continue to fine tune every detail of the technique necessary to drive a car at its technical limit. The best part (besides hydraulic pedals)? I can practice with my coach, Thomas Merrill (that hyperlink is to a cool test drive he did in a 458), virtually, for hours on end. I’ve never done anything that requires so much concentration and through which I lose all sense of time. Sometimes I tell my wife I’ll be “simming” for 45 minutes only to have her come out and tell me it’s been almost 2 hours. Another added benefit is that I get to teach my kids about driving while they sit on my lap. Fun for the whole family, really. Except my wife, although she has learned to fly through the corkscrew at Laguna in a Miata. I initially planned to put the sim in our bedroom, but that idea was vetoed in favor of the garage. Better than nothing, but I don’t see why the bedroom was such a bad idea.

On the track, my best blooper so far was an amazing failure of metallurgy going into turn 2 at Buttonwillow. Admittedly I tried to cheat and shift from 4 to 2, instead of 4 to 3 to 2, but still… c’mon…

 

Update 5: Family

Speaking of family, and since I do get asked (thank you very much), my family is doing great and especially happy to see me under much, much less stress than when I was a full-time fundraiser. And as far as kiddos go, it’s still amazing to think there was a day when I didn’t want them (in the abstract, not my actual kids). So glad I was talked into it. The little guy is, officially, a monster. At his 18 month check-up he was 99th percentile in height and 91st in weight. Probably not going to be a great jockey. Big sis adores him and hasn’t (yet) got sick of him. She plays drums like it’s her job and he dances like it’s his.

Update 6: What I eat (the only update you care about…)

In 2015 I did a 6 month experiment of exactly one meal per day (23 hours of fasting, then ~1 hour of eating at dinner). Very interesting. I’m sure I discuss it in at least one of the podcasts, below. These days I’m eating about as freely as I have in 7 years. I’m still carb-restricted by the standards of most Americans, but nowhere near the ketogenic lines of 2011, 2012, and 2013. I almost always skip breakfast, and lunch is usually a salad (“in a bowl larger than my head,” if possible). Dinner is usually a serving of meat with more salad and veggies. I’m more liberal on fruit and even occasionally rice or potatoes. Also, in moments of weakness I sometimes lean into my kid’s crappy food.

The biggest “news” on my eating front is that I now wear a 24-hour continuous glucose monitor (CGM) 24/7. This was the result of one of the most fortuitous flights of my life. In the fall of 2015 I was flying to NYC and half way through the flight, needing a short break from work, I went to one of my favorite watch sites. The fellow next to me made a comment—clearly he was part of the cognoscenti—and we got ultra-deep into watch idiotness. After a while I asked him what he did only to find out he was the CEO of Dexcom, the company that makes the best CGM device on the market. Fast forward a week and Kevin has introduced me to his amazing team (Christy Pospisil is awesome!) and I’m hooked. CGM is a game-changer and it does warrant more discussion than I can provide now. The insights have been staggering. I’m pretty obsessed with it (shocker, yes) and I aim to keep my 14-day running glucose around 90 mg/dL with spot-check standard deviation less than 10 mg/dL. By keeping average glucose low and glucose variability low, I can reasonably assume my insulin AUC (area under curve) is low.

Below is a printout of my last 14 days. As you can see my measured average glucose was 92 mg/dL, which imputes an A1C of 4.8%. At some point I may write about the dozen insights gleaned from CGM (and I think I mention a few in the podcasts), but here’s one: measured A1C is probably directionally valuable (you know, the difference between, say, 5% and 9%), but that’s about it. If your RBC (red blood cells) live longer than 90 days—mine live much longer since I have beta thal trait—your A1C will artificially reflect a higher average glucose. Conversely, if your RBC are large, the opposite occurs. (For those wondering, MCV, which is part of a standard CBC, shows you RBC size).

My A1C in standard blood tests routinely measures 5.5% to 6.0% (courtesy of my tiny RBCs), which poses a problem when applying for life insurance (prediabetic is defined as 5.7% to 6.4%). But with CGM, which is calibrated 2-3 times daily, my imputed A1C, which is much more reliable, varies from 4.6 to 4.9%. Big difference, huh? As an aside, I can’t talk about my beta-thal without hearing my med school roommate, Matt McCormack referring to them as “shite for blood” in the best Scottish accent ever. As if it’s not bad enough having an artificially high A1C… you gotta have shite for blood.

And that’s the least amazing part of CGM. I’m not sure I’m at liberty to discuss the next generation of CGM. Admittedly, not too many people want to wear the device I wear, but in two years, well, that’s when it will get amazing.

And that’s just the tip of the iceberg when it comes to why this device is adding insights and actionable data at a geometric rate. In two years this device will evolve into something everyone can wear.

 

And lastly…

Ok, I can’t think of any other updates so with that below are three podcasts I’ve done in the past 3 or 4 months. By some coincidence all of them have gone live in the past week, which is what prompted me to do this post-that-is-not-really-a-post.

Here they are in the order they were recorded.

  1. Rhonda Patrick and I spoke in Fall 2015. Here is the link to the video, which she nicely annotates. I believe this is also available on iTunes.
  2. Ken Ford and I spoke in January of this year. I was honored to be the first speaker in IHMC’s STEM series. Here is the link.
  3. Chris Kresser and I spoke in February of this year. We planned (before the talk) to discuss lipoproteins, but I don’t recall doing so. Here is the link.

I hope these three podcasts—all of which were really fun discussions—keep you occupied for a while. I have not listened to them, but my recollection is that there will be overlap between them, especially the latter two.

I’ve been asked a lot in the past few months to do other podcasts but I’ve politely declined, noting that I’m a bit podcasted out. I’m sure the energy will return next year, assuming I have something to say.

  1. Great to hear from you, Pete. Was the break away from NuSI because you were overworked and wanted to do your new practice, or is it because of something else? Just curious as you were so passionate about it in the past.

    Hope you can come back semi-frequently to update us.

    PS – That car sim looks like the most fun an adult male could have.

    • It have been following you from quite a long time. I really liked your idea about LCHF diet and your pursuit of cracking insulin resistance/ Type2 diabetes epidemic.

      I just read newly published paper in nature w.r.t Cause of Insulin Resistance in Type 2 Diabetics (http://www.nature.com/nrendo/journal/vaop/ncurrent/full/nrendo.2016.46.html)

      My father had Type 2 diabetes and i think i have pre-diabetes/Insulin resistance with fasting blood glucose of 105.

      I knew beforehand that high carb and sugar is the leading cause of diabetes, so i had reduced the carb intake and increased the fat intake. I have always been an active guy and do rigorous strength training and weight lifting performing high volumes and high intensity,still my fasting blood glucose came high.It was a shock to me!

      Thereafter i was wondering, why even after cutting down on carbs/sugar and excising regularly my blood sugar was on upper side.After reading the new nature paper, it gives insight that High fat intake and along with high BCCA supplements is detrimental to insulin sensitivity.

      I had started high fat diet an year ago (i am vegetarian but i eat lot of eggs, cheese and butter ) and had BCCA intakes along with my Protien shakes which by itself has BCCAs in them.We also know that proteins also break down into BCCAs. I had reduced the carb intake and increased the fat intake.

      Before starting high fat diet with BCCA my FASTING. blood sugar was in 90’s.

      I thought of sharing my health and metabolic profile to you after reading this Paper. Are we missing/ignoring something in our fight against insulin resistance.Please share your suggestion.

  2. Hi Peter. I am blown away by your approach to health and longevity. I have very similar goals to you in my part-time practice of a small scale, individualized health promotion and disease prevention practice. I am not looking to create a global institution, but I am looking to be part of something amazing that helps people in ways that cannot be done elsewhere. Since I started this process a year ago, I have been looking to organize or join a team that could accomplish this better than any individual. As luck has it, I am in San Diego (I have even run into you at the Bay Club). Now that I see you are delving more into clinical practice, I feel I need to stalk you until I can convince you to sit down with me and chat. Although I will readily admit I am not near your stratosphere of intelligence and detail in your thought process, I also have to admit that I am as passionate and committed as anyone when it comes to truly helping others make a positive difference in their lives. I bet you didn’t know you had a job opening, yet here I am applying for it. Let’s sit down and if you think I’m full of hot air, so be it. But I bet with my help you could reach more people with more success and perfection than you realized. You’ve got nothing to lose and potentially a whole lot to gain. Plus I’m getting tired of looking all over the gym every time I am there to try to find you!

  3. Welcome back!

    At one time, you were insulin resistant. Obviously, you are currently very insulin sensitive. Now that you’re not restricting carbs as much, what do you think changed in your physiology (i.e., which adaptations do you think persist despite an increase in carb consumption)?

    Did you gain any insights into the cascade that led to your insulin resistant state?

    • I echo Wab’s comments Peter. I believe I am also insulin resistant. I so enjoyed your podcast with Tim Ferris. It is the sole reason I started taking berberine; you were the catalyst and thank you for that.

      Any chance you can tell us how reintroduction of carbs has been for you? I think I listened to a podcast of why you decided to reintroduce carbs occasionally but can you expand/illuminate?

      I am toying at moment and following the “Eat Stop Eat” program. I am hypothyroid but I was a competitive tennis player (played college tennis) and I love exercize., Flash forward, I am now almost 52 years old (and take one tablet of desicated thyroid every day (60 mg Armour) and until recently, I wsa the heaviest I have ever been since I gave birth. Hmmm… I have lost 15 pounds the last 3 months doing Intermittent Fasting (Eat Stop Eat). The fasting has not been an issue for me (I like the structure and the fact I don’t have to worry about food the two days I fast). I have also started lifting again and I feel much better. This will be a lifestyle change/journey for me but any advice you can share would be most welcome.

      Thanks in advance for your help!

  4. Thanks so much for the update and of course for all the great information you’ve provided for so many years!

  5. I just listened to the great podcast with Rhonda. You help remind me that there are no simple causes or solutions to chronic health issues and so much more to learn. Thanks for sharing your knowledge.

  6. Great blog post Peter.

    I’m highly envious of the weather in all these pictures! Even the family pictures, don’t think I’ve seen palm trees and puffy winter jackets together before…well maybe at the Dubai indoor ski hill.

    You have better luck with your in-flight seating than I ever have, most interesting guy I sat next to snored so loud the noise cancelling on my headphones couldn’t even cope with it.

    Re Squats, you ever used a safety squat bar? Pretty much the only thing I can use due to some shoulder and elbow issues…probably down to years of bad posture.

    Cars; open driving invitation if you ever end up in the area during the non skating rink seasons.

    -Ryan

  7. Thanks for the update, looking forward to the book. By the way, I’m very jealous of your racing-sim rig, my wife would never allow such a (fun) extravagance. Before marriage I would spend hours on Grand Prix Legends – nothing like spending months trying to master the majestic Nurburgring Nordschleife in a Lotus 49. The demands on concentration alone give you enormous appreciation for the guys who risked their lives in the real machines on real roads, but also why they did it.

    • Yea, my respect for these guys is at another level. If you haven’t seen it, the documentary “1” about the evolution of F1. I’ve seen it somewhere between 23 and 25 times…mostly when wifi dies on airplanes and I reach for the ipad.
      To think that Niki Lauda went sub-7 min on the Nordschliefe in the early 70’s is unreal. I won’t tell you how long it took me to do it the first time in the sim… I have two more years before I’m ready to go to Germany and give it a shot.
      My ultimate goal is Formula 2000, which my coach thinks is doable in 2 years.

  8. Your 14 day glucose chart is effin insane, I’m incredibly jealous! I wear a Dexcom, too, and it’s radically changed my T1 diabetes management in a huge way. I can’t say enough how much it has helped me better manage my disease, and I thought I was doing a pretty good job prior to getting it. I’m coming up on my first endo appointment since having it for more than a couple weeks, and I’m looking forward to seeing the results of how this device has helped me.

    I am very interested in, and excited to see the next gen CGM that you suggest in the post. If they need some very active people to do some field testing of the new system, please pass along my name and email address. I do a lot of running and hiking, and would probably be a good tester for any new system they have in development. 🙂

    Thanks for your continued posting and the information you pass along, Dr. Attia, it is much appreciated. Best to you and your family!

    Andy

    • Andy, don’t be jealous… I have a freakin’ pancreas, man! I did comment to another reader about the amazing work of Jake Kushner at Texas Children’s. Look him up. He’s getting incredible results in his T1D kids. A1Cs in the 5’s without hypo.

  9. I’m a Type one diabetic and only wish that my health insurance would cover a CGM. My A1C is always in the low to mid 8’s with my endocrinologist on my back all the time. I have been limiting my carb intake and exercise 6 days a week cycling 3 days a week avg 60-90 miles and weight training the other three days. My cholesterol is within good rages without medication and BP is within normal range. I’m 68 years old and consider myself to be in good health at 5’11” and 210 lbs. except for diabetes. Any suggestions in obtaining a CGM?

    • Lloyd, I wish I could help with this. I think everyone with diabetes–T1 or T2–should have CGM. Jake Kushner who runs the T1D program at Texas Children’s has the Dexcom on all of his patients. They have A1Cs in the 5’s without hypo episodes. Maybe reach out to Jake and his team?

  10. Hey Peter, thanks for the update! Very cool stuff. I’ll be looking forward to hearing more about your CGM experiments – I have flirted with the idea of doing that when I read about it in The 4-Hour Body.

    Is NuSI working on finding out whether certain blood marker results (like LDL-P) can mean different things based on context, such as diet? I.e. does a high LDL-P under a ketogenic diet display a different level of CVD risk vs. the same number, but with a standard American diet?

  11. Thanks for the update Peter, I would love to know more about the insights you have gained from CGM both from a health standpoint and possibly for exercise/sport performance. I loved your talk with Rhonda, just wished it was longer, was actually taken back when it seemingly abruptly ended. Then again, I use “Overcast” to listen to podcasts which shortens/eliminates pauses in conversation so it was sped up a bit.

    4 Questions:
    – Have you or will you explain why you left NuSI
    – Have you done any research or used an HRV device like “Omegawave”?
    – Do you still hold to the insulin model? If so, have you or might you give a response to the seemingly convincing 3rd hypothesis put forth by Stephan Guyenet, found here – http://wholehealthsource.blogspot.com/2016/01/testing-insulin-model-response-to-dr.html

    Thanks for all you do Dr. Attia! You are in the fortunate position, to be able to benefit so many more people then those who actually respond and say thank you… in other words, more then you realize 🙂

    – Marcus

    • 1. I’ve said all I want to say about NuSI
      2. I’m pretty interested in HRV, but struggling to find the “right” device. Ditto for a great sleep device that can accurately record stage III and IV of sleep.
      3. Do I look the kind of guy who want to spend 20 hours on a back-and-forth blog debate? If I want to debate this topic, I just call Stefan and we discuss it like a couple of gentlemen.

      • I’ve already got what I consider the best sleep cocktail on earth, which I supplement as needed. Still in search for a great monitor. I’ve outsourced that my good friend Kirk Parsley. He’s still looking.

    • I would so fund a Kickstarter campaign to have Peter and Stefan have that insulin discussion as a video/podcast.

    • Hi Peter,

      Regarding your comment re the Sleep device, you need to check out the OURA Ring.

      I’ve tried and tested so many devices over the years (fitbit, jawbone, beddit, various iphone apps etc) for myself and my clients, and the OURA ring is by far the best.

      As soon as they launch their coaching platform I will be switching all my clients over to it.

      It looks a bit ugly at first, but you could simply use it only at night and take it off during the day if you just want to track sleep.

      I actually have a comprehensive review on my site with a few videos and an interview with the OURA founder.

      https://www.alexfergus.com/blog/the-one-wearable-to-rule-them-all-oura-ring-review

      I know this probably sounds like a sales pitch, but it’s not. I’ve been a long time reader of your site (I discovered you a while back when you were on Ben Greenfields show). Anyway where I saw your comment about the sleep device I just wanted to give you a heads up about the ring because it may be the solution that you’ve been looking for.

      All the best.

      Alex

  12. Great to hear from you, Dr. Attia! Thanks for updating and sharing your life with your loyal community. It sounds like things are going great and only changed for the better for you in 2015. Looking forward to your coming longevity tome!

  13. Good stuff as always!
    I don’t believe I had heard of the IHMC until I began following you and Dominic, but I keep wondering if I had ever run across something about them a long time ago seeing how I graduated from the University of West Florida in 1994. Computer Science and Psychology were very large and well funded sections of the uni though. That was well known. I was, however, always way in the back of the campus in the Biology and Chemistry building. Although I did spend many nights studying in the very nice 24 hour computer lab on campus. The poor physics department was always overlooked as it was relegated to a small space on the 3rd floor of the monster Psych building. UWF is an interesting campus because it is also a very large state nature preserve which enabled our field biology professors to find interesting ways of dragging their lab classes all over the far corners of campus and keeping us for the full 4 hours or so allotted for labs.
    Interestingly enough too my Mom drove a brand new, manual transmission, 325e that my Dad got them for something like 10 or 15 years and when they finally sold it I think it was to somebody that was going to set it up for racing. My Dad always said that Eta engine ran like a perfect sewing machine. My Mom loved that little car. That was the first vehicle I ever got up to just over a hundred miles per hour while driving on one of the back roads at the beach. Lots of on demand torque but you had to watch that red line because you would get there fast. I actually got her hand me down Datsun 810 which had the same straight 6 that was in the same generation Z of the day. The Nissan/Datsun designers had even reverse engineered the Bosch fuel injection system for that engine. Good times.
    Maybe do a post sometime on watches and your horological opinions. I fear it may become a lost art one day now that we all carry tiny supercomputers in our pockets these days. Always good to hear from you.

    Dan

    • Dan, the first car I ever drove was a 1988 E30 325 in 5 speed. As a 15-year old I would sit in the garage and practice shifting for hours (it was my older cousin’s and he kept it in our garage). So it was really cool last year to transition to this car…
      One day I should do a post on my other obsessions…watches, pens, Secretariat, Senna,… I’m a pretty obsessive guy. Thanks for humoring me.

    • I think it’s hilarious that the engine blocks in the early-80s BMW M12 F1 engine that produced close to 1500 BHP, were taken from the 2002 series road cars that had at least 100k km on them. From 80 BHP to 1500. I guess you can make a silk purse out of a sow’s ear.

  14. Thanks for the update. Your comments about beta-thal resonate with me as I have microcytic anemia and elevated HbA1c. I’ve also coincidentally been dabbling with continuous glucose monitoring using a device called the Freestyle Libre which is intermittently read via NFC from a phone or dedicated reader (ie not a continuous display). Being from the North of England with Viking heritage perhaps I may have some beta-thal trait. Must dig into that.

    • Dear Peter,

      Your report of muscle loss with 23:1 fasting is alarming!

      For all those experimenting on their own with fasting protocols,
      Would you please explain your belief that the link was due to your meal timing?

      Have you seen Jason Fung’s essays on fasting to reduce insulin resistance? He blogs at Intensivedietarymanagement.com
      Fung is a practicing nephrologist in Canada who has written a series of very clear explanations of a model of the hormonal causation of obesity and type 2 diabetes — a persuasive elaboration of the insulin hypothesis.

      Lots and lots of people, including both women and men of all ages, are fasting in efforts to reduce insulin to improve their health. (or, perhaps, to look like fitness models?)
      But if significant muscle loss is the result, then their efforts might backfire. They’d be failures again, just like they were after trying, and trying again, to follow Weight Watchers and other low-fat calorie-restriction diets.

      Help! They need to learn what they can about fasting from you too.

      • Context matters, Jane, so please don’t get too upset! Jason is treating people with T2D. If they lose a few pounds of muscle, but everything gets better, that’s a huge win. I’m starting from a very different (already very insulin sensitive, low body fat, etc.). I can’t, in a short comment, provide more insight into this, but I’m sure I will at some point in the future.

  15. I’m glad things are going well and that you seem to have found more balance in your life. It’s not easy trying to fit work and family in, and it seems like you were unimaginably busy!

  16. Great to hear an update Peter. I noticed you were no longer on the NUSI site so was interesting to see what you are focusing on. Auto-racing sounds very cool!! I wish my parents could have taught me to drive on a sim racing around Laguna Seca!
    As always, interesting to hear how you are eating. I think I’ve followed a similar ketogenic path. There’s something about the perfectionist pursuit of very low-carb and ketone-tracking, but relaxing the restrictions a bit, especially by skipping breakfast, makes compliance a bit easier and stress-free for me. Though now you’ve peaked my curiosity in this GCM tech!
    Looking forward to your book and good luck with it!
