Ketosis

What I actually eat, part III (circa Q1 2014)

Craving vegetables.

Read Time 10 minutes

This week I had dinner at a great steakhouse in New York with a very good friend.  Like any two “normal” guys after a long day, all we could talk about was science, and on this particular night the topic du jour was NAFLD (non-alcoholic fatty liver disease for the non-cognoscenti).  We ate, we drank, and we shook our heads in disbelief at the thought of 7 million children in the United States being afflicted with NAFLD.  In the next few years NAFLD will become the number one indication for liver transplantation (not a typo).

After dinner, my friend, who I dine with almost every time I’m in NYC, made a comment about how many vegetables and how much fruit I consumed.

I had the following: a chopped salad, tuna tartare, a 12 oz filet; and we split an order of sautéed onions, brussels sprouts, and a bowl of berries.

He asked, “How are you able to stay in ketosis with all of those carbs?” I responded, basically, that for the past few months I have not been consistently in ketosis, and when I am it’s only following a long bike ride where my BHB levels may get back into the 2-3 mM range. Most days, however, I live in the 0.3 to 0.8 mM range, depending on the time of day. (In my mind, to reap the benefits of nutritional ketosis, one probably needs to consistently be in the 1-3 mM range, and for some “applications” 3-4 mM is probably ideal.)

So what gives, you may be thinking. Is Peter Attia not Mr. Ketosis? Well, my friend suggested it might be time for another one of the dreaded what-do-I-eat posts.

Anyone who knows me or who has read this blog for a while will appreciate the fact that I loathe talking about what I eat. Why? Because, it unfortunately gets interpreted by many as what they should eat. It’s like asking me what exercises I do, and inferring you should do the same. It doesn’t make sense.  I have specific genetic factors, epigenetic alterations, and goals.  These factors coalesce to shape my behavior – how I exercise, what I eat, what I supplement.

A little backstory first

In September of last year, for my wife’s birthday, we went to our favorite restaurant in San Diego, where we live. The day before I emailed the owner and general manager, both friends, and asked for them to have one of our favorite off-menu items on hand (the best sushi in San Diego).  They happily obliged and asked which of their desserts my wife would most like.  I said something to the effect of: well, they are all great, so you pick.

The next evening, after eating more sushi and sashimi than I could imagine (I ate 3 platters myself), they brought out a platter with a full size serving of each of their signature SIX desserts, each with a lit candle.  We sang Happy Birthday, blew out the candles, and my daughter and wife, themselves already stuffed, proceeded to have a small forkful of each of the six desserts.  My daughter said, “Daddy, these are so yummy! Why don’t you have a bite?” To which my wife echoed, “Yea, they really are ridiculous…”

And in that instant, I made a decision. I did something I had not done in 4 years (to the month, actually). The decision was this: about 3 or 4 times a year (I opted for my wife’s and daughter’s birthdays, Thanksgiving, and maybe something else), I would – for one meal – eat whatever the hell I wanted.

In the next 15 minutes I devoured the remaining 4/5-ths of EACH of the six culinary masterpieces in front of me.  From cheesecake, to carrot cake, to decadent ice cream, and stuff I didn’t even recognize, I ate it.  In an instant I felt both wonderful and horrible.  The look on my wife’s and daughter’s faces – alone – was worth it. Their jaws on the table the whole time. The taste was beyond what I remembered (actually, much sweeter than I remembered, probably because when you don’t eat sugar for 4 years, well, you know).

I could barely get up from the table. That night, when we got home, I had a horrible headache. 1,000 mg of Tylenol and 2 glasses of water later, I still couldn’t sleep. I eventually got a few winks of sleep. The next day I felt hung over – a feeling I had not experienced since my 26th birthday. My fasting glucose was 126 mg/dL and BHB was 0.2 mM. Clearly I was out of ketosis.

I decided to go out for a glycogen-depleting workout (multiple sets of 3 min all out intervals on the bike) and about 36 hours later, after resuming my normal diet, I was right back into ketosis and felt just fine.  I told my wife I was going to repeat this experience on Thanksgiving. As such, and despite how far in advance this was, I asked her to plan to make an extra bowl of my favorite Thanksgiving dish – candied sweet potatoes – baked sweet potatoes coated in melted marshmallows.

Thanksgiving came and went, and I repeated the same act of debauchery during the big feast. Sure enough, by the Sunday morning of Thanksgiving weekend, I felt back to my baseline.  I haven’t gone on a bender like that since, but I’m probably due for one.

I’m sure at least some of you are asking, “Does Peter still think sugar is metabolically deranging?” The answer is absolutely, at the levels it is consumed by most Americans.  If you want a refresher on my point of view on sugar, definitely give this post a re-read.

So what did I take away from this?

Somewhere between “every day” and “never” there is a tolerance I have developed to consume massive amounts of carbohydrates, and specifically sugar.  Now, there are two components to this: a purely physiologic one and a behavioral one (which I suspect is heavily influenced by my physiology).

Focusing just on the physiology, I would guess I could probably “tolerate” a binge like that every few weeks with little measurable or discernable adverse effect.  I won’t even attempt to argue whether it’s every 7 days, every 14 days, or every 30 days.  But, it’s probably somewhere in that vicinity.

What about the behavioral side? Well, I suspect there exists a different “frequency distribution function” that describes how often I could binge like this without resuming unhealthy eating habits in the long run.  If I had to guess, I think the threshold for recidivism is higher from the behavioral tipping point than it is for the physiologic one. In other words, habits matter. I can probably tolerate – physiologically – more sugar today than I can tolerate behaviorally.

One last point I’d be remiss to leave out. You should keep in mind that for a period of 4 years, my consumption of sugar (sucrose, HFCS, liquid fructose in the form of any beverage, etc.) has been less than about 5 grams per day.  The average American, depending on which stats you believe (I think they are all pretty weak), consumes somewhere in the neighborhood of 100 to 120 grams per day of sugar, NOT including the liquid fructose in juice!

So, I have to at least entertain the hypothesis that 4 years of avoiding sugar has been a sufficient enough period of time to offer me some sort of “metabolic reset.” Now, I have no intention of testing this. If I was once susceptible to insulin resistance, I’m pretty sure I will always be. But, an interesting Gedankenexperiment would have me going back to one of several different dietary patterns – vegan, but with no sugar; standard American diet with lots of sugar; modestly higher carb, but still sugar-restricted – all could offer insights into the physiology of adiposity and fuel partitioning in my metabolically reset condition. 

How has this shaped my current eating behavior?

Sometime early in the New Year, I started really craving more vegetables. I’ve always loved them. Even in ketosis I still ate one or two salads each day most days, but I was pretty restrictive about the quantity of vegetables that had much carbohydrate in them (e.g., tomatoes, carrots).  But now, I wanted even more.  Big heaping bowls of curry stir-fry. (I have to toot my horn on this one thing. I make a really good, creamy, spicy curry stir-fry.) I realized this would probably knock me out of ketosis, especially with the large amount of tofu I mix with it and the yogurt I use to make the sauce.

My lunchtime salads were getting bigger and bigger, and I was piling more and more “stuff” into them. Almost laughable by the standards of those around me.

And I noticed I was eating less meat. Not at all by “design,” but somehow by seemingly craving less.  It seemed an average week would have maybe 2 servings of red meat.  When a great steak is placed in front of me, believe me, I enjoy every bite, but I found I just wanted it less. I also started craving a bit more fruit, especially berries and even apples, the former I consumed in modest amounts in ketosis, the latter I did not at all. (Because I know someone will ask – do I think red meat is harmful? – the answer is no, I do not believe so. Certainly not based on evidence I’ve seen to date, including the recent story about protein. For those looking to brush up on the state of evidence implicating red meat, I’d recommend three posts – one I wrote many moons ago in response to one of the dozen epidemiology stories, one written by Chris Masterjohn in response to the TMAO data, and one recently by Zoe Harcombe in response to the protein epidemiology).

I don’t know what to make of this, of course, and it may be nothing at all, other than an evolution of preference. I’ve checked mineral levels in my body in search of a clue (none showed up). Maybe I’m over- or under-saturated in some key nutrient?

Now, since everyone seems to care how much carbohydrate I consume, here is my current framework.  I put carbohydrates into 5 essentially MECE categories:

  1. Those I consume daily – mostly salad stuff and other vegetables; about twice a week I make a curry stir fry with tofu, for example.
  2. Those I consume often – nuts, berries, almond butter (which I just spoon out of the jar), super starch (both as a meal replacement and post-workout drink).
  3. Those I consume intermittently – a couple spoons of rice here and there, especially when I make Indian food or when we have sushi; a piece of baked potato when it looks particularly appetizing. If my daughter “makes” spaghetti, which she loves, I’ll usually have a forkful to remind her that her dad is not a complete freak.
  4. Those I consume only on very special occasions – exceptional desserts, for example – about 2 or 3 times a year, like the ones I consumed on my wife’s birthday, or the candied yams. (NB: One thing I decided in an instant – if I’m going on a bender, it’s not going to be for “average” dessert like some lame birthday cake; it’s got to be best in class.)
  5. Those I still completely refrain from – I call these the “cheap” carbs – basically all else (including cookies, potato chips, cereals, and the candy bars they keep handing me on this flight as I type this), including any liquid form of fructose, such as juice or sports drinks.

Below is a “typical” 5 days of eating over the past few months. Keep in mind, I virtually never consume breakfast, maybe once a month (e.g., if I have a breakfast meeting). Essentially, I do all of my exercise (current routine, below) in a fasted state only consuming the BioSteel’s high performance sports drink (HPSD), which contains virtually no calories – maybe 8 kcal of BCAA per serving.  So, despite the dietary changes I’ve made, and the fact that I’m not in ketosis most of the time, I remain seemingly well fat adapted, though RQ is a bit higher than before.

I should point out that I spend much less time exercising than I have historically, due to time constraints. But, I still aim for the following schedule, which is interrupted by travel during at least 2 or 3 weeks each month. The schedule below amounts to about 14 to 16 hours per week of training.

Monday – high intensity lift, followed by swim

Tuesday – ride (tempo)

Wednesday – swim

Thursday – ride (TT practice or threshold)

Friday – high intensity lift

Saturday – ride (VO2 max intervals), followed by swim

Sunday – group ride or solo TT practice

I can’t believe I’m about to do this…I just have this horrible feeling someone is going to attempt to replicate this, bite-for-bite, for no good reason. Please refrain. Remember, this is what I eat because of how my body works.

Wednesday

Lunch – huge salad (bowl larger than my head) with romaine lettuce, kale, carrots, tomatoes, cucumbers, olives, mushrooms, chicken breast, 2 tbsp olive oil, 3 tbsp lemon juice, 1 tbsp white vinegar, 1 cup of almond slivers

Snack – a cup of macadamia nuts

Dinner – Another large salad, but no chicken or nuts in this one; 1 pound of salmon; bowl of berries to follow

Thursday

Lunch – huge salad (bowl larger than my head) with romaine lettuce, kale, carrots, tomatoes, cucumbers, olives, mushrooms, can of tuna, 2 tbsp olive oil, 3 tbsp lemon juice, 1 tbsp white vinegar, 1 cup of walnuts

Snack – 2 or 3 tbsp of almond butter (a zero sugar variety)

Dinner – Omelet made from 6 eggs (white + yellow), shredded cheddar, lots of other veggies; side of steamed broccoli in butter; 2 more spoons of almond butter after dinner

Friday

Lunch – same as Wednesday (I basically rotate salad back and forth about 3:1 in favor of chicken over tuna)

Snack – none

Dinner – Curry stir-fry containing tofu, carrots, broccoli, bell peppers, mushrooms, zucchini, and squash, in a sauce made from curry paste and Greek yogurt.  I typically consume two heaping plates of this.

Saturday (post ride and swim)

Lunch – 7 hardboiled eggs, an avocado, 2 oz of cheese

Snack – a Fuji apple covered in almond butter

Dinner – 8 oz of steak (fillet, rib-eye, or tri-tip), 8 oz of salmon, large salad (sans meat and nuts, which I only do with lunch salads).

Sunday (post longer ride)

Lunch – The “Peter Kaufman” super starch shake (heavy cream, zero-sugar almond milk, a package of chocolate super starch, 2 tbsp of almond butter, an extra 20 g of Biosteel whey protein, frozen strawberries, ice – blend to a thick shake); I’ll drink 2 liters of this. Literally.

Snack – none

Dinner – Family sushi night! I’ll have a seaweed salad or two, huge platter of sashimi, California roll, and another specialty roll.

Lastly, because I know someone will ask, the few times I now take to measure, record, and tabulate exactly what I consume, it works out to about 3,500 kcal per day.  But some days, especially when I travel, it can be as low as 2,000 kcal when I only consume one meal per day (dinner). Other days it can be as high as 5,000 kcal. But, 3,300 to 3,600 kcal per day is the typical range. 

So, there you have it – the most irrelevant information you’re likely to find on this blog (except for what’s below… this is actually valuable stuff!)

Fashion tip of the month

While in NYC I realized – about 15 minutes before leaving my hotel for a very important meeting – that I had forgotten to bring cufflinks. My heart sank. I’ve never made this mistake before. I immediately realized why.  While packing, and just about as I was going to grab a set, my phone rang and I was distracted.  But that was neither here nor there. What was I going to do?  I didn’t have time to buy a new set, and the hotel concierge didn’t have a set to lend me, so I grabbed some dental floss and tied the cuffs of my shirt together using precise surgical knots.  I was pretty self-conscious that someone would notice and ask or comment, especially on a day stacked with so many back-to-back important meetings. Amazingly, no one said anything, though I could see some people looking at them and doing the double-take. Over that lovely steak dinner I alluded to at the top of this post, I told this story to my friend (who snapped the picture, below).  His response?  “Yea, I noticed it right away. I thought it was a new style. Very cool, actually. Kind of European.” So there you have it.  Don’t say I never shared anything of value on this blog.

  1. Hi Peter,
    You stated you perform VO2 max intervals in your bike. I assume that with your keto diet, you probably do not have stored glycogen in your muscles. Does the lack of glycogen impair your intervals performance? Or, is it unnecessary to have stored glycogen to perform intervals at full tilt?

    Thanks

  2. Dear Peter,

    Great Post, as usual.

    You mentioned in this entry that you do not fully understand why you are eating more carbohydrates (e.g. your body is missing minerals, etc). Have you considered that maybe you are eating more carbohydrates because they are addictive and the reward center of your brain is telling you to do so?

    Take care,

    I.

    • Well, there might be some reasons as to why now and not before:

      1) Before you were really extremely careful/conscious with your diet, and avoided consciously carbs
      2) Maybe now you are relaxing a bit for various reasons: it takes a lot of self-discipline to be as close as possible to KT; family matters or work gets in the way and, let’s face it, the day only has 24 hours.
      3) then you relax a bit your diet -taking more carbs- and the brain is fooling you to talk more…

  3. Thanks for sharing your nutrition/training info, always interesting to read what other LCHF/Paleo/Primal athletes are doing.
    Re dental floss cufflinks: Fantastic! I’ve ended up using paper clips when going to the opera… 😀

  4. I think it’s a bit misleading to include salad as 100% carbohydrates. Metabolically, the important thing is not what enters your mouth, but what enters your blood stream. So starch hits the blood as glucose. Lettuce hits the blood as short-chain fatty acids (butyrate & co). Very different effects on the body!

    I minimize carbs that digest to glucose, but eat unlimited carbs that digest to fats. Just another way of eating fat, effectively.

    And I also find myself craving salads on a regular basis. Given how nutritionally poor a salad is, I can only imagine that once the nutrient deficiencies of the Modern American Diet are made up, your body needs a less nutrient-dense diet and is looking more at maintenance nutrient loads plus fuel.

  5. I believe I have read (or heard) somewhere that one of your primary reasons for continuing with the ketogenic diet despite having already substantially achieved your body re-composition goals was due to the positive effect ketones have on your brain. Are you experiencing any adverse cognitive effects now that you are not regularly in ketosis (e.g. memory, focus, anxiety, stress etc.)?

    • I notice a difference when I’m hungry, which I find is a state I’m more often experiencing today than in full NK. So when I’m hungry, today, I feel much less “on” than the pseudo hungry times in NK, when BHB levels were rising, and I could feel paradoxically better.

  6. Hi Peter,

    First of all, I’d like to thank you for all the work you have done, I have learned a lot from you work over the years and truly appreciate you giving away all this information for free. However, I take exception to a few things in this post. First, you say you seem to have built up a tolerance to consuming large amounts of carbohydrates. However, feeling “hungover” and not yourself for a couple days after these binges hardly sounds like a tolerance to me. In fact, it sound like the opposite seeing as people who eat SAD day in and day out go on binges like this all the time and it hardly affects them. And as for the behavioral shift you noticed, this seems like standard conditioning to me, no need for fancy terms like “frequency distribution function”. You ate a ton of carbs, got sick, so your brain said don’t repeat that anytime soon, that wasn’t cool. I’ve noticed this in myself. I know pizza is good, and would love to have some, however since I’ve started eating in a non-SAD way I get sick everytime and just know its not worth it.

    • Sure, the 2 episodes of eating *massive* amounts aren’t really what I mean. What I’m wondering — not asserting — is if eating the odd baked potato or bowl of rice *today* would have the same effect on me metabolically that it would have pre-2009.

    • HAD to chime in here.

      I have done both – a debaucherous, dirty carb refeed while in ketosis, and a “clean” – sweet potato and white rice refeed while in ketosis. The morning-after symptoms between the two were day and night apart, every single time (so it certainly wasn’t a one-off thing influenced by some third factor).

      Food consumed during the Dirty refeed (Kiefer’s Carb-Nite) in a 3-4 hr. period in the evening: 1 Chocolate Eclair, 1 Donut, 1 piece of Tres Leche cake, 1 medium deep dish pizza. Woke up in the middle of the night feeling dizzy and nauseous, had a pounding headache the next morning. Had no idea what was happening since I had never experienced a hangover before (I don’t drink). Did a dirty refeed a few weeks later, same thing happened again.

      Food consumed during the “clean” refeed in an 8 hr. period – 2 sweet potatoes, 1 yam, a few servings of white rice, some rice krispies cereal with skim milk. No hangover-like symptoms at night or the next day. Only adverse symptoms were the water retention and gassy-bloat from the sweet potatoes. Did this again the following week and results were identical minus the bloat as I reduced sweet potato quantity and upped rice and rice krispies.

      My brain absolutely sent me the “pls. don’t do this again” message with the dirty refeed and it didn’t with the “clean” refeed. So if I were to eat “clean” carbs in modest amounts (and not refeed amounts) occasionally, I certainly wouldn’t get the “pls. don’t do this again” msg. from my brain, and I am guessing it would probably be okay metabolically as well. Of course, the possibility of behavioral derangement / carb-creep is a different story, something I personally have to really watch out for.

  7. another thoughtful, generous post by the great Peter Attia. you’d think if i had something to say, it’d be about the post itself.

    but no, all i can think about is that luscious, naughty marshmallow concoction. my obsession with it is a bit startling, given that for about 13 months i’ve not eaten, nor been tempted by any kind of sugar, starch or grain. not a crumb; not a taste — i went cold turkey and that was that.

    but i’m sitting here, thinking longingly about those gooey yams. and while i’m no chef, i’d consider toasting the marshmallows before adding them to the dish. yeah. i’d toast the marshmallows. in fact, i’m considering to make a big batch of it, sit under the kitchen table and eat it all by myself.

    and bite anybody that comes near me.

  8. Peter, Do you notice any body composition differences in days after the binge? After the excess water is again released back on my normal VLC diet, I do feel as if I’ve possibly renewed the VLC fat burning effectiveness and believe there is some truth to the above mentioned John Kiefer carbnite. I suppose I am vain for asking lol. Thanks for your great work.

    • I definitely gained weight, in the ballpark of 3-5 pounds overnight, due to water, both intravascular and via glycogen. I probably don’t have a discerning enough eye to notice a huge difference.

  9. Hi Peter,

    I always look forward to your monthy post! It would be fun to take a poll on your “coming soon” page (maybe let people choose their top 3) to see what people are most looking forward to you writing about. I checked, and I don’t see e Apo E or Cholesterol part X there, which you mentioned doing. I hope that you can do them some day. It looks like this post will not disappoint you as one of the most commented!

    • I’ll definitely get to a part X of that series. It’s just a post like that will take 20 hours to do correctly (vs. one like this which can be done in 4 hours). I haven’t had a spare 20 hours since early 2012…

  10. I have a burning question: When you spoon almond butter straight out of the jar, do you double dip?

  11. Dr. Attia,

    First off, excellent post as always. I have an interesting question for you that is actually pretty unrelated to the topic of this post. What are your thoughts about the similarity in structures between Beta-hydroxybutyrate and Gamma-hydroxybutyrate (GHB)? I came across an interesting medical hypothesis on pubmed (https://www.ncbi.nlm.nih.gov/pubmed/17011713) that speculates about the implications of their structural similarities. However, this lead me to another article (https://www.ncbi.nlm.nih.gov/pubmed/17011713) that demonstrates that a GHB-analogous receptor ligand synthetically constructed had anticonvulsant properties in the brain. As far as I know, the mechanism of the anticonvulsant nature of the Ketogenic state has not been fully quantified. Is it possible in your opinion that the structural isomerism between GHB and BHB could have a hand in the Ketogenic diet’s ability to treat seizures?

    Thank you for your time

  12. Hi Dr. Attia,

    As always, thanks for posting – all I can say is “wow”. Should be a headline, “Peter Attia Out of Deep Ketosis, film at 11” I have to process this a little bit. I think you were our collective ketosis “wingman”. When the going got tough, we knew there was a dude down in San Diego that was just killing it so we should persevere. (Okay a little tongue in cheek but not completely) But of course your journey is not our journey and glad you’re still sharing what you’re up to.

    I’m curious about your comment regarding very deep ketosis, (3-4 mmol) which has some “applications”. Could you say what those applications might be?

    thx,
    Eric

    • Eric, I could still be “killing it” in ketosis if I wanted to, and I’m sure I will again when I fancy the time as right. But don’t use my being in ketosis or not as any barometer for you! There are countless people in ketosis. I’m just one idiot who is stupid enough to write about it.

  13. Hi Mister Attia,

    I’m french and i Love your web site! I just would like to know if a low carb diet is better or worse for bodybuilding. Many people say to me “if you want to build muscle (and i want;) train but dont cut the carbs”. So i dont know what can i do? Stay lean without muscles or building muscle… And fat.

    If you could answer it could ne great! Again congratulations for your work!

    • I know little about BB, but I suspect a cyclic approach is best. The low carb AND low fat (i.e., highly calorie restricted) phase is probably best for show-time preparation. So BB is really about multiple phases.

    • Hi Julien,

      If you’re interested in cycling carbs as Peter suspects may be the right approach, you might consider visiting “body.io”, which is John Kiefer’s website. He has a couple of ways he recommends doing it which may or may not be useful to you.

      You might also consider Volek and Phinney’s latest book regarding low carb for athletes. In there they do agree that insulin can increase amino acid uptake into muscles. But they assert that only a relatively small amount of insulin is needed for a large effect. So pounding cherry turnovers after a workout to create a large insulin spike may not be needed or desirable.

      I bought some superstarch with protein to use after my weight workouts in the hopes I might get some “carb backloading” effect in the manner Kiefer recommends without interfering with ketosis. I haven’t tried it yet but was gratified to read that Peter says he often uses that product after lifting weights.

      Good luck,
      Eric

    • Thank you Peter (or doctor as you wish) ! i don’t know if it’s a cliché but i love the state of mind of your country (i ask a question , the next day i have an answer even two;)

      Tank you Eric too, that’s very nice! But there something i dont understand with J.Volek. In his book “TNT diet” he says that the best thing to do for bodybuilding is low carb 5 days and high carbs 2 days (even pizza!). He calls those 2 days “the reloading time zone” but in his new book “the art science of low carb performance” if i understand well, he says that carbs are not necessary at all and could even getting things worse. So what can i do? And hear pur official”keto-boss” peter attia saying that low fat is good (!!) make me in trouble.

      Again Peter, congratulation for your work and what you’re doing on this wonderful web site

  14. “What I’m wondering — not asserting — is if eating the odd baked potato or bowl of rice *today* would have the same effect on me metabolically that it would have pre-2009.”

    I believe I experienced such a metabolic “reset.” After years of low-fat, high-carb vegetarianism a slightly alarming FBG (102) led to a pretty long period of VLC, but likely not ketogenic, eating. I lost quite a lot of weight became very lean—friends thought I might be seriously ill. Eventually I gradually reintroduced carbs, though I did continue to abstain from grains except for treats now and then. I eat white rice (in the way Asian cultures do), fruit, dark chocolate, even candy treats now and then.

    I’d say I’m now LC, certainly compared to the SAD, but not VLC. I did gain back a few pounds, but I’m still very lean and I seem to be able to eat pretty much what I want now and stay that way. I’ve decided that’s a good trade-off for me, and with fasting TG of 20 and HDL of 160 I’m not too worried about IR.

    Sushi (and other Asian cuisines) are our favorite, too, and I’m very pleased to be able to eat them frequently now, with the rice! What I don’t know is whether I could go back to all the bread, grains, and pasta and stay lean. I have no intention of finding out, but my sense (just that, I can’t be certain) is that I am now much more metabolically flexible and resilient than I used to be. I suspect, but again can’t prove, that IF (eating in an 8-hour window) and Doug McGuff-style high intensity strength training has contributed as well, and allowed me to become more carb-tolerant.

    • Hi Peter,

      My personal case lead me to ask you a general question. I fallow a strict low carb diet since 18 months right now and and i’ve lost 15 kilos in 6 weeks but i’m still in overweight (about 3kilos, i can see very well my handles). So i’m on a plateau since a year. Do you think it is possible that the plateau is breakable after after few months/ years more, just the time for the body to readapt?

      Thank you very much.

  15. Hi Peter,

    thank you so much for all the valuable work and information!

    After a few weeks of reducing carbs, I went ‘all-out keto’ two weeks ago, and I feel great! Only four days of transition were hard when I felt weak.

    Having been competing in a sport at national level (in my respective age group) for more than 20 years, I’ve seen quite a few ‘trends’ in sports nutrition, trying everything and eating my way through the whole variety of spots bars. Competition weekends were especially bad: loads of sugar, sugary drinks and only a proper dinner.
    Nutritional discipline with bouts of binging during the week were regular.

    So I mainly decided to go keto to stop the cravings for sweets, and it works.

    In 2009 I first tried the cream diet as developed by Götz Heine (Munich, Germany) and had amazing results, both in weight reduction as well as in performance. But you wouldn’t want to keep that up for an extended period of time.

    Being a sprinter, what might be the right time to switch back to more carbs before the main competitions? I’d be grateful for any thoughts on that.

    • I don’t know much about sprinting, but it’s probably more a function of creatine phosphate than glycogen during competition. Training, of course, will certainly require adequate glycogen stores.

  16. Pete,

    A question I have been hoping to hear you answer (and maybe I’ve missed it) is one you allude to in this post:

    “I have specific genetic factors, epigenetic alterations”

    You say you don’t like it when people think what you eat is what they should eat, and of course we all have genetic and epigenetic factors that would lead us to different ways of eating.

    Here’s my question: what kind of blood tests should be doen to find those out so we aren’t spinning on the hamster wheel thinking all we need to do is lower our carbs? I’ve heard you talk in some podcasts about blood panels you order for your patients. I know you can’t give medical advice here, but can you give an example of what kind of blood tests you order for insulin sensative patients you see? It’s so frustrating trying to find out what’s going on sometimes when you get one size fits all advice from professionals.

    Thanks, Pete.

  17. Forgive me, I am am new to this kind of food post, but while reading all the comments there are a number of abbreviations I just don’t understand. I poked around a bit in some previous posts but just got more confused. Sorry.. Is there a place where I can look them up?

  18. Dr. Attia.
    I’m a big fan. Was curious about your current weight and waist circumference.

    • Excellent. Your blog is a life saver. Found your site in October. I am 45 yrs old, started at 194lbs now at ~170. Was on cholesterol meds for over 10 yrs.. stopped taking the meds after 2 months of LCHF diet.
      Still on BP med. Do you have any recommendation that would improve my Blood Pressure?

  19. After submitting the above comment I realized I hadn’t even asked the question that has me puzzled for quite a bit. We have eaten a sort of modified paleo -no gluten (wheat and other), no margarine or other Omega 6 loaded stuff, and basically nothing from the centre aisles of the grocery store-, lots of veggies, often stir fried in lard or butter.
    Felt great on it, but recently, because of some hype in the blog sphere started with adding a tbsp of resistant starch (potato starch) to the yogurt and before going to bed a little bit of yogurt with RS and a teaspoon of honey. Got the honey idea from Seth Roberts. Now I discovered a ‘spring’ in my step that wasn’t there before. I don’t know what else to call it. Feels like some ‘lightness’ in my muscles. I am 72. I know about the gut flora and how the commensals are happy. I also realize that there is increased serum acetate, which makes the brain happy. But the spring in my muscles?
