    Going complete vegan

    Actually, the hypochloridria argument is cited by vegan activist but I never looked up the literture, which however does support some ratio of hypocloridria (20%) in >65-70 years individuals (for example: https://link.springer.com/article/10.1007%2FBF01540281) Also, the Canadian GI website publishes a table with some known causes of B12 deficiency or impaired absorption, only one of which is a vegan long-term diet. https://www.badgut.org/information-centre/health-nutrition/vitamin-b12/ Condition or State Causes of Deficiency Absence of vitamin B12 in the diet Vegan diet (long-term); poor intake of vitamin B12-rich food Lack of adequate intrinsic factor Gastrectomy, pernicious anemia Inadequate intestinal absorption Gastric bypass surgery, small bowel surgery (especially in the ileum), disease in the ileum (Crohn’s disease, cancer), short bowel syndrome, fistulas Poor digestion of food Reduced gastric acid (>65 years of age, gastric cancer, H. pylori infection) Failure to digest salivary R protein Pancreatic disease, lack of pancreatic enzymes Other malabsorption syndromes HIV, multiple sclerosis Congenital disease Transcobalamin deficiency Receptor or mucosal defects Long-term use of certain drugs like H2 receptor antagonists, proton pump inhibitors, Metformin, antacids Altered use of intestinal organ Bacterial overgrowth, long-term TPN, tapeworm

    Unfortunately I'm not a fan of frequent blood analyses, which would also constitute a major cost here if most main minerals and vitamins should be analysed. I opened a thread with my recent blood analyses, taking B12, zinc, iodine supplements, and after a couple of months sunbathing. Iron was good as well D3, both with natural sources, no supplementation. Among the analysed parameters homocisteyne was beyond the upper normal range, I described the possible causes and the supplementation strategy I'm trying, bsaed on choline, TMG, cycles of B complex vitamins . Should I try and get enough choline from plant-based foods, I should gorge on mushrooms and tofu.

    Smio, thanks for the appreciation. By the way, probably the best reference to try the vegan regimen is Brenda Davis-Melina Vesanto book: 'Becoming Vegan-comprehensive edition'. Choke full of useful suggestions by academic authors.
  4. As Todd says, the average value governs. However, your question would be relevant to a CR regimen which does not reach all nutrients needed. The correct answer in this context would be 'priority to caloric restriction', and the possible deficiency issue may be solved by: Using a targeted supplementation (easy way) Designing a diet which hits the CR target with the average minimum amounts of all nutrients (difficult solution). This entails optimization strategies, often by trial-and-error using apps like cronometer. The optimization works like a game, trying to find out the combination of foods which minimizes calories and maximizes nutrients at the same time.

    If your problem is supplementation, then you should follow a mixed diet, probably vegan-pescetarian, with mussels for B12 and fat fish and flaxseed for omega3s/D3. A few years ago I was against supplements but they allow you a wide freedom of choice as far as dietary regimens go. Valte Longo himself advises supplements 2 or 3 times per week, beside his vegan-pescetarian diet.

    There are probably 4 main levels to regard the nutrient issue, with respect to a well balanced omnivorous diet in an efficiently digesting less than age-50 individual: Basic nutrients: the only one nutrient which absolutely is missing in a plant-based regimen is B12 , as gordo says; pls note omnivorous individuals and those wth little stomach acidity especially if over 50 may exhibit B12 deficiency as well Basic nutrients but controversial or related to phenotype (genetic polymorpisms): D3 may be lacking if you have not the opportunity to sunbathe regularly or have unfavourable genes. EPA-DHA may be missing if you are a bad converter ALA→EPA-DHA; Retinol may be missing if you are a bad converter carotenes→retinol. Iodine may be present in small amounts. Some of the precedeing are controversial, for example persons of colour in northern climates whould all get ill if not eating huge amounts of fat fish. Nutrients which may be deficient in a plant-based diet in some conditions. For example zinc, lysine, Tiamine, Niacin and so on, but this is the same for non-vegan people, certain fixed eating habits may bring about deficiencies Nutrients which are not believed to be really necessary but may be useful, like choline, creatine and so on. There is an excellent sticky post by Michael Rae on advised supplemetation regimen for vegans. Also, using an app like cronometer may give you valuable hints. last, checking the hints with regular blood analyses will make you sure that the vegan transition will be painless. all the above has been discussed in previous threads. I myself made the transition from lacto-ovo to fully vegan (99%) 2 years ago, with excellent results. An adequate strategy is necessary though.

    Exercise optimization

    This is some shredded look after a FMD if I remember well
  8. KP, I fully agree, fact is that trinity sounded better than quaternity, LOL But of course quaternity it is, sleep is king!
  9. I never thought about flu vaccination; in my case, the immunity boosting trinity (Whole diet, exercise and cold exposure) seems to work far better than any vaccine. When taken together, these three practices seem to be a pretty powerful combo. Of course, that may be not true for everyone. Also, I noticed that not everyone is able to expose consistently to cold .

    "I hear you're on a special diet"

    It would be interesting to know the sequel to such episodes, who knows, the least likely to be interested might be the one who eventually takes up the regimen.
  11. kpfleger, AFAIK the only aspect Longo insists upon is that healthy individuals only need a FMA once or twice each year. he doesn't provide quantitative data though, as far as I remember. Dr Joel Khan, the cardiologist and vegan activists, is very lean and healthy but practices FMD once each month. He's an enthusiast of Longo's FMD so I must guess he finds it beneficial even if he's so health conscious. Again, he provided no quantitative details.
  12. Yes, the guys who commented that video seem to be a bunch of absolute purists of the vegan diet. By the way, I too had an opportunity once to realize on myself how much exercise can make a glucose spike drop down. My fasting glycaemia was anomalously high, about 98 mg/dL. I had my usual dark cacao with dark muscovado, walked briskly 20 minutes on the threadmill, glycaemia was in the seventies. Knowing that, sometimes I indulge with cacao & honey before exercise. I can understand how the continuos mild exercise of the people in the blue zones of Okinawa, SArdinia, Costarica and Ikaria was ideal to dampen those peaks (which to begin with were probably not remarkable anyway).
  13. Wearing a continuos glucometer sure has its distinct benefits. I would have liked a different vertical scale on the blood glucose time series, it was hard to see spikes and troughs.

    Cronometer results for the FMD

    It's interesing to notice the bodyweight variation after the FMD. The weight has risen over the pre-FMD value and beyond in 17 days. It took 2 weeks to recoup the full pre-FMD value by eating a whole foods, plant-based diet without much restraint. My present BMI is 23.7, which includes an increase of both muscle mass and bodyfat.
  15. I was amused by the sophistry with which he arguments that they aren't prostitutes.
