I'm going to detail the 36 hour thing because it's still a wee bee in my bonnet. One of the central tenets of Juddd, if I understand it correctly, is that DD calories are so low that we are effectively fasting from our last meal on an UD till our first meal on the following UD, roughly 36 hours later. Jaminet recommends a 16 hour fast (for optimal autophagy, etc.) and says that for many, longer fasts are not advantageous. He also says that longer fasts are therapeutic for some people. Which are you? How can you tell? No idea! So I keep wondering how many of us are suited to Juddd as written, or are we suited for short run but not long run, etc., etc. in my little n=1 world, I seemed to hit grooves where it was perfect for me, and other times during which it didn't feel good, and the good grooves weren't always correlated with weight loss. It's like weight loss and feeling great were two independent markers. Anyway, this bit still makes me curious. Hope that explains the 36 hours. ![]()

I find that I can get through most DDs within my calorie limits. I experience some hunger, but it comes and goes. I'm most hungry around the time that I go to bed, and I wake up hungry during the night, and especially hungry when I get up the next moring. I'm very hungry at the start of my UDs, but I am usually satisfied by my UD calories, especially if I eat high-volume foods like a huge salad with raw veggies and greens and full-fat dressing with 2 T. oil in the dressing. I had a difficult time with hunger when I cut my protein back to 60 grams or less per day, initially, and substituted fat calories, but I've gotten used to that. My macro calorie percentages are 75-85 percent fat, 10-15 percent calories, 10 percent or so carbs on up days. On DDs, I was eating mostly lean protein, but lately I've been doing just fluids (bone broth, water, tea, coffee with cream once or twice a day). As my DDs have gotten less hungry over time, but my UDs have gotten hungrier. I think my body has figured out it's only going to get much food on UDs, and it DEMANDS "Feed me!" (like the plant Audrey in "Little Shop of Horrors"). I spent years trying to (unsuccessfully) limit my weight by eating only 1 meal per day, often just a chef salad day after day. I actually get hungrier now than I did then, but I know I am eating a much healthier diet now and am indeed healthier and feel better. So getting better nourished doesn't really correlate with less hungry days for me. ![]() |

Edit- sorry about that. I am always late to the party and apparently misunderstood the question anyway. I read Blonde's question, went to write it out and post it and see it was answered meanwhile. I can't keep up with this thread now!

Correct me if I am wrong everyone. JUDDD is done on an every other calendar day basis, so, for example, you go to bed on Tuesday night, and you're restricted to your DD calories or so until Thursday morning (unless you're up at midnight, which most people aren't (So it's effectively 32 to 36 hours of "fasting.") So if my last meal on Tuesday was at 8:00 PM, 8-midnight is 4 hours. From Tuesday midnight to Wednesday at midnight is 24 hours. From midnight on to 8:00 Am on Thursday, is another 8 hours. That would be 36 hours. It depends on when your last meal is and when you break the fast. The 16/8 is fasting for 16 hours and eating within an 8 hour window. I stop eating at 8:00PM and start up the next day at noon. I don't know if you can get SIRT1 from the 16 hour window however.

Thank you Joyjoy for your thoughtful reply. I felt really good doing JUDDD most of the time. Good enough to keep doing it without any weight loss for long periods. Do the 5\2 16\8 fasts still have the sirt1 benefit, do you know?
Svenska-I've also heard something about low carb causing high bg readings in fasting bg but I wasn't sure if this applied to me? All I know for sure was a fasting bg reading of 118 on less than 20 carbs per day. One other thing want to say regarding the NK diet. I felt really good! Clear headed and strong, not tired or wimpy. I was enjoying it until my bg and cholesetrol levels came in. That scared me, I'm 57 and I don't want to eat myself into a heart attack. It's so hard to know what to do. I want to lose weight, I want to be healthy, I want it to be easier than it is and it's just not easy at all. It seems so much harder now than ever....

On the activation of the SIRT1, I remember reading this:
In mice it has been shown that a 24-hour fast activates SIRT1 and that the increased activity is still measurable more than 24 hours after the end of the fast. This effect is not unlike that which my colleagues and I have observed in asthmatics. Not only were their markers for oxidative stress reduced after only one down day, indicating the rapid onset of SIRT1, but after following the Alternate-Day Diet for several weeks and then stopping, their symptoms remained improved for approximately 10 to 14 days, suggesting that SIRT1 was still active and its downstream effects were still operating. Johnson M.D., James B. (2009-04-07). The Alternate-Day Diet: Turn on Your "Skinny Gene," Shed the Pounds, and Live a Longer and HealthierLife (Kindle Locations 785-789). Penguin Group. Kindle Edition. But we are men and women, not mice, so who knows? Maybe a question for Sunday to ask Jaminet. Last edited by sungoddess; 02-02-2013 at 04:08 PM.. |

Hey gang, I have to run, but Bev & Kristin answered perfectly. I still have the whole Sirt-1 going, or so I feel, but it could be the benefit of just fasting frequently? Or it could be the ptero? I will ask Paul.
And Sven, I was talking to you. I have some thoughts but need to come back when I have a bit of time. Hang on friend. Last edited by sunday; 02-02-2013 at 04:12 PM.. |

Something appealing about the PHD (and about some other approaches like Paleo) is that the emphasis is on real foods that generations of people all over the world have recognized as healthy: bone broth, fermented vegetables, egg yolks, liver, cold water fish, meats and vegetables, healthy fats used for generations. So even if one didn't follow the PHD exactly, I think just about everyone could benefit from eating a lot of the foods that this plan emphasizes. That can be reassuring in a world where there are so many competing diet plans and so much conflicting nutritional advice, I think. |

Yes, since that post, I backed off NK. Take a couple epsom salt baths/week. And am improved in that respect. No serious cramps for a bit. Have used Morton lite salt for years which is 50% potassium and had previously kept the leg cramps at bay. The all over spasms was new since NK and since I wasn't losing weight there seemed no reason to continue down that path.

I get my fermented food in the form of fermented vegetables that are sold in the refrigerated section of my food co-op. Some common kinds are sauerkraut and kimchi (with the latter also sold in Asian markets). I am enjoying lacto-fermented green beans and "autumn salad" (mostly cabbage with some other veggies added), which are made by a local small farm producer, too. I also eat Greek yogurt fairly often (and have considered making it from scratch).

Sven, I love kimchi when I can find it. Here, I'm at the kefir and loving it. I'll keep my eyes open.
Sunday, I would LOVE to hear what Paul says about sirtuins and fasting length. I would be beyond the beyond if he felt 16 hours did the trick. (Sorry Blonde, I forgot to answer that part of your question by saying I have no idea.) ![]() |

For 40 years, I was a vegetarian, and I ate very little junk food, no fast food, and almost no sugar; yet, despite exercise (I walk wherever I need to go) and limiting food intake (often eating only 1 meal a day), my weight crept up to be just under the "morbidly obese" category. I made a very sincere effort to lose weight when I turned fifty, working with a nutritionist and a personal trainer and exercising 2-3 hours a day on top of my usual walking. My nutritionist told me that I wasn't eating enough, so I upped the amount that I ate; after that she described my diet as "fabulously healthy." I also worked with a physician open to alternative medicine, and took various actions like adding supplements and detoxing from mercury. None of this led me to lose any weight, and I tried for about 9 months. ![]() About a year ago, I read Gary Taubes' book and realized that I might have to severely limit carbs and give up being a vegetarian, since I had all the signs of metabolic syndrome/marked insulin resistence. I began following Atkins, and after a couple of months modified it to include just healthy food I prepared myself, with no frankenfoods--a primal approach (paleo with organic dairy). I was losing so slowly on that (1 pound a month) that I limited protein to do NK (which helped some) and then added JUDDD. So now I do low carb/moderate protein/high fat, track and measure/weigh everything, stick to JUDDD rotation calories, and have learned about and implemented a lot of traditional health foods (as in "Nourishing Traditions"). Much of what is consistent with the PHD is what I've been eating for several months: liver, bonebroth, free-range duck eggs, organic non-starch vegetables, seaweed, wildcaught coldwater fish, greens, coconut oil and butter, pastured beef, fermented vegetables, Greek plain yogurt, organic pastured butter and cream, cold pressed nut oils, olive oil, flaxseeds, avocados, nuts, and raw milk cheese are the things I normally eat (and no grains, no starchy vegetables, no sweeteners of any kind, no preprepared/convenience foods). Even doing all that, I lose slowly. Fortunately, I don't have any serious health problems and can afford to pay for very high quality healthy food, and I only have to cook for myself, so there are no temptations in my kitchen. I don't have problems with craving other kinds of food, and I never ate junk food regularly anyway. The main things I wish that I could add to my diet are more fruit and some starchy vegetables (beets, carrots, yams), but I'd rather be losing weight than eating those foods. Sorry to be so long-winded, and I really hope that everyone else here finds that she can get to a healthy weight, just by following PHD recommendations, more or less, and eating within a limited time window. ![]() Based on my history, I'll need to do more (maybe counting carbs and calories and doing JUDDD rotations the rest of my life), but I can live with that, so long as it allows me to get to and stay at a normal/non-obese weight, eventually. I'm following the PHD thread to see others' experience and to learn other useful things I can incorporate into my own plan--such as limiting my protein intake to an 8 hour window and eating fats with minimal or no protein if I eat outside that window. (I can do that. |

Unfortunately, although I like to do cardio and resistence training, my weight loss seems to stop dead when I do either, so I'm sticking to walking, stretching, and very gentle qi gong and yoga/balance exercises for now. But I think that I'm unusual in this respect, and I don't want to discourage others from exercising. When I get closer to my goal (or at least am "overweight" rather than "obese"), I'll try exercising more again and see what happens. ![]() |

I scoop out the bones and big pieces of meat and onion before I chill bonebroth, but I don't strain it completely because I like a few little bits of meat in it (and I watch very carefully for bits of chicken bones). I wonder how I could put eggshells into my bone broth ... maybe tied into a bit of cheesecloth, like one does with bouquet garni, for easy removal? Anyone have experience with bonebroth plus eggshells? |

One time I made beef broth that was only partially jelled, and my guess was that I hadn't cooked it long enough/down enough. But it usually works. Maybe roasting the bones also helps with bringing out the gelatin, as well as deepening the flavor? I roast bones (or parts, such as chicken and turkey wings, with bones) for an hour at 400 degrees before making broth (turning once). I'm sorry you are having so much trouble. ![]() |

Last time I found giant turkey wings, roasted those, and used those in my broth, and I got a beautiful gelatin. Problem is, they don't often have turkey wings at either of my stores. But they made a delicious broth and I was thrilled with all the gelatin. Thanks for helping me problem solve this! I think the joints in the wings may be a solution. |

I just checked "The Naked Foods Cookbook," and the recipe there says if you add a Tablespoon of whey, the mayo will keep for "several months." I really need to try making my own mayo. I have light olive oil, avocado oil, and macademia nut oil, which are all supposed to be mild enough to make good mayo, and I have a recipe. I think I was traumatized by mayo that didn't set, decades ago, and haven't tried making it again, ever since. I end up substituting organic full-fat sour cream for mayo, to avoid eating the store kind with polyunsaturated fats. |

Wow Sven! You have been busy!
![]() I think we may be twins. It is going to take me a bit to catch up to everything you have posted, but as you were posting, I was reading up on MDA, Mercola, Ori Hofmekler, Brad Pilon, Martin Berkhan and other IF supporters. I can't get past the fact that women do not have the same results that men do. Unfortunately. Although I believe fasting is very good for our body, I can't help but believe that not every person gets the same benefit. Some women suffer. And some women will not lose. I have watched our JUDDD budds as well as many other IF'ers and see the same exact complaints. Some women flounder on IF. ![]() Sven, I am impressed with everything you have done for your health. Great research and your dedication to finding what works is undeniably resolute. I think your perseverance reminds me of the determination that I have felt since I began this weight loss & health journey 5 years ago. I can't say that I have done as much as you have, but I knew that when I began fasting, it was only a very small piece of the puzzle. I knew that I needed to eat the right foods and whether it was forever giving up wheat, sugar, or carbs, I needed to know that it was not only going to help me lose the rest of this excess weight, but in the process bring me good health. Maybe perfect health. I am not fearful of potato or starchy veggies/fruit as much as I am fearful of not obtaining good health and longevity. Weight plays a big role in being healthy and especially in women. So, as you probably have heard me gripe, my weight doesn't budge at times and in fact, it really likes staying steady. In many ways, though that is a huge relief. Before JUDDD, I would be so confused when my weight kept creeping upward. My losses are so slow that I have perfected maintenance on 950 calories, well, that is actually the average of 1600/300. I hope that you will stick around here and let us in on anything you learn, as we are all trying to learn PHD and it takes a while to really grab a hold and digest much of his teaching. Please read his website and go to the Q&A. I find that he does answer questions. I tried to ask a question last week for Dawn that never was answered, but I think I may have put too much extra in the question to make it confusing. Also, please don't lose hope. I saw and read about Erp (who is 77 and discovered PHD) she lost down to her goal weight and is finally in the best health that she has ever been in. Jaminet uses her as an example quite a bit and she reports back with some of the knowledge that she has gained.

I make cilantro pesto and eat 1 T. every up day because my body tends to hold onto mercury, and cilantro and selenium (found in some nuts) are a natural detox for mercury. And cilantro pesto is tasty, too. I combine 1/3 cup raw brazil nuts, 1/3 cup raw sunflower seeds, and 1/3 cup of raw pumpkin seeds with 2 cups chopped cilantro and 1/2 cup flaxseed oil and some salt in a food processor; puree; store in fridge in dark covered container. Cilantro is available year-round and is cheaper than fresh basil, which are other advantages of using it in place of basil.Last edited by svenskamae; 02-02-2013 at 08:14 PM.. |

Sven-
I am going to try your recipe for the cilantro pesto. I eat cilantro regularly for the mercury detox. The pesto sounds more fun than eating it plain. Regarding my chocolate question and sugar and amount, I found the answer. In case there is anyone else interested-- I'm on my way to winning a Nobel prize!! I hope Chocolate: What is the Optimal Dose? Posted by Paul Jaminet on November 3, 2012 Bret asked us how much chocolate is needed for good health: I have a question about having dark chocolate daily. Does it need to be every day or what is the mininum grams per day. I have been having around 35g a day of 70% but I wondered if less would be ok or not having it at all. Chocolate Is Not Considered Essential … Yet Chocolate has not yet been recognized by the Food and Nutrition Board of the National Academies as an essential nutrient. We haven’t either: Our food plate lists it among “pleasure foods,” which are healthful but optional. However, we are becoming ever-more chocolate friendly. In the new edition of our book, we list chocolate among our “supplemental foods” which we recommend consuming regularly. But our suggested dose is “as desired.” Perhaps we should narrow that down a little. Chocolate Against Cardiovascular Disease We’ve previously warned of the danger of chocolate deficiency, based on a systematic review that found: “The highest levels of chocolate consumption were associated with a 37% reduction in cardiovascular disease and a 29% reduction in stroke.” Here’s a visual summary of their findings: Chocolate Against Diabetes Bret was concerned about the sugar in chocolate, but if this is a problem, it’s outweighed by the benefits of chocolate. A Japanese study found that the rate of diabetes was reduced by 30% in those who consume the most chocolate. Chocolate Against Dementia and In Support of Cognitive Function Several studies have found that chocolate consumption reduces risk of dementia and enhances performance on tests of cognitive function. One of them found that cognitive function was optimized with a relatively low dose of chocolate – ten grams per day: The associations between intake of these foodstuffs and cognition were dose dependent, with maximum effect at intakes of approximately 10 g/d for chocolate and approximately 75-100 mL/d for wine, but approximately linear for tea. The other found that cognition improved with intake of cocoa flavanols up to quite high doses – elderly given 1 g/day cocoa flavanols performed significantly better on cognitive tests than those given lower doses. Unfortunately I don’t know what fraction of chocolate is made of flavanols. I’m guessing it’s not more than a few percent, in which case this research suggests the optimal dose of chocolate may be 50 g/day or more. Chocolate in Support of Circadian Rhythms Most authors attribute the benefits of chocolate to their flavanols, which are thought to improve endothelial function and increase blood flow to the brain, among other effects. However, there are other active compounds in chocolate, include peptides that interact with the opioid receptor. The opioid receptor has a role in circadian rhythms, which is one reason low-dose naltrexone (which blocks opioid function at night) works. It’s possible that eating chocolate during the day may support circadian rhythms via opioid receptor stimulation, especially if the peptides can reach the systemic circulation. Indirect evidence that this may be beneficial comes from a Russian study in which exorphins (opioid receptor ligands) were injected into rats: The chronic intraperitoneal administration of the peptide at the same dose of 5 mg/kg significantly increased exploratory activity, decreased anxiety, and improved learning. I don’t know how much chocolate would have to be eaten to achieve a similar exorphin dose in humans, but I imagine it’s large. Chocolate in Support of Nobel Prizes So how shall we resolve the issue of optimal chocolate dose? For me, the decisive evidence comes from a recent study by Franz Messerli published in the New England Journal of Medicine. Based on chocolate’s support for cognitive function, he decided to see if chocolate consumption was related to another measure of cognition – Nobel Prize awards per capita. He counted Nobel Prizes and compared them to the recipient’s country’s chocolate consumption. These were his findings There is clearly a strong correlation. The correlation coefficient is .79; p < 0.0001. The correlation coefficient if Sweden is removed increases to .86 – which is suspicious: Given its per capita chocolate consumption of 6.4 kg per year, we would predict that Sweden should have produced a total of about 14 Nobel laureates, yet we observe 32. Considering that in this instance the observed number exceeds the expected number by a factor of more than 2, one cannot quite escape the notion that either the Nobel Committee in Stockholm has some inherent patriotic bias when assessing the candidates for these awards or, perhaps, that the Swedes are particularly sensitive to chocolate, and even minuscule amounts greatly enhance their cognition. Those dastardly Swedes! Giving themselves more Nobel Prizes than their chocolate consumption warrants! But I apologize, I’ve been diverted. The key point is, is there an optimum chocolate consumption? the dose–response curve reveals no apparent ceiling on the number of Nobel laureates at the highest chocolate-dose level of 11 kg per year. 11 kg/yr is an average of 30 g/day. So benefits are still increasing at that dose. Of course, this was only a population level study. We still need to measure the doses in individual laureates to gain confidence. But anecdotally, there appears to be a correlation: “I attribute essentially all my success to the very large amount of chocolate that I consume,” said Eric Cornell, an American physicist who received the Nobel Prize in 2001. “Personally I feel that milk chocolate makes you stupid. Now dark chocolate is the way to go. It’s one thing if you want like a medicine or chemistry Nobel Prize…but if you want a physics Nobel Prize it pretty much has got to be dark chocolate.” Dark chocolate is, indeed, the PHD-approved form of this highly beneficial food. Conclusion This dose-response data might not be strong enough to define an RDA, but I’m going to take a stand: Bret’s intake of 35 g/day is healthy. Indeed, it’s right in line with the Nobel Prize-maximizing chocolate intake of the Swiss. In regard to your last question, Bret – can you eat less chocolate, or none at all – the answer is clear. Yes, you can. But you must accept the consequences. You probably won’t be winning the next Nobel Prize for Physics. |
