    How many calories for me to maintain my weight?

    Probably around 1900 Calories according to this calculator. Although, it says I need over 1900 Calories to maintain my weight yet I eat about 1500 Calories per day. I still think you should probably not do CR until you reach skeletal maturity. Didn't you say you were 18 in the other thread?
  2. If you wanted to get her DNA and sequence it, you'd need to create a reason or scenario to have her body exhumed for DNA testing. Claiming that she was a fraud and not even who she says she was would be what you'd probably need to do. I don't think the claims by the Russian guy were taken seriously anyway. I know that sounds kinda crazy, but it's what I thought after reading his paper. 😄
  3. I'm not a conspiracy theorist but the cynical side of me thinks that someone would claim this because it'd would be the best way to get her DNA.

    Body fat percentage?

    I see where others are coming from because your body is still developing and you could jeopardize your growth into a more adult-like (male) body. So you need to think about if you're willing to accept (potential) consequences of severely restricting calories. Things such as not being as tall as you could be, having a smaller frame (including less broad shoulders), not having a deep voice, and other characteristics which are considered masculine. I don't know for sure that these are affected, but I would take it seriously. And being so skinny might make it harder to get into relationships in the future as well. Can you stand up straight with your shoulders back and the camera more body level? I was trying to just get an old similar pic I took when I had a BMI of 16 just to compare. Photobucket is being rubbishing right now (as it usually is) so I can't access it. I don't think 18 is too young to start eating a really healthy diet and just staying lean but not underweight. Starting this early assume that there is much room for improvement beyond the current functioning of your cells and body as a whole. I started this journey when I was also around 18 years old (35 this Oct) and I continued more seriously at 20, and then ended up with a BMI of 16.3 or lower which I maintained it for about 6 years. Then I increased it to 17.5 (intentionally) for a few years. It's hard to see my trajectory if I hadn't done CR. I'm only just over 5 ft 7" and my brother and father are much taller than me. I have the small body frame, even when I went to my sister's wedding, I was like 1 size away from a boys suit rather than men's because my shoulders were not very broad. Didn't really develop any overly masculine features, very boyish (teenage) voice (even often referred to as a girl on the phone.) All that might've not happened even if I didn't restrict to just 1500 K/cal for years (and now back at 1500). Or it might've happened anyway due to genetics and whatever other factors were involved. I do feel though that I may have interrupted my development to an extent. But it just so happens that I'm perfectly fine about all of that. I have zero regrets and I'm very happy about my decision. It was probably one of the best things I could have done. But now imagine yourself 10 years from now. You're a 28-year-old dude and CR is old news. We have senolytics and other therapies which are far superior. Now you're stuck with many of these features because you deprived yourself of energy while you were still developing. Yeah, you could bulk up, do some weights... but would you have preferred to be taller? Have a bigger body frame? Broader shoulders? Many of these things matter if you're into girls, it's what they're attracted to. Even though I have a site partly about CR, I would not recommend people do it at 18 or even 20. Earliest would be 25. Think more about the consequences...

    Blood Pressure

    I don't think you should be concerned if you're not experiencing any symptoms. This is pretty normal for most of us on CR. My blood pressure is usually around 90/60 with a HR usually between 50-60 when I'm home. At the doctors, it can be quite a bit higher. I tend to get a bit anxious and I'm running around not relaxed. This is pretty common though... When I first started doing CR I did get a little dizzy when standing but over time I seemed to just adapt to it. Low blood pressure is likely a good thing as long as you're not experiencing any bad symptoms from it. If the association between very low LDL cholesterol (common in CRONies) and hemorrhagic stroke is real, then having low blood pressure + low inflammation would be good at preventing any increase in risk IMO. And if your arteries aren't clear, then as mike said, low blood pressure could be an issue.
  6. This thread reminds me that it's probably time for some more blood tests. I haven't done any in years... Only measured Testosterone twice 516 ng/dl (2013) 412 ng/dl (2016) Ref: 8.8 - 36.7 nmol/l (260-1080ng/dl) https://docs.google.com/spreadsheets/d/1V6gvGoCnZGqcr-sR5TuFY4TKLr4mj_X6f7TlXJaLwk4 I've also taken Finasteride since the end of 2016.

    CR sleep ... some useful tips at last!

    I really don't understand the skepticism of Matthew Walker's work around here or what he is saying that is wrong. You'd personally ignore his book.. have you read it? He works for Google (One of their Alphabet companies) so they trust him 😛
  8. I watched the whole thing and thought it was pretty interesting. A bit over my head to be honest, but surprised they were already working with rats and monkeys using the technology "An abstract in a Neuralink whitepaper published today notes that the system could include “as many as 3,072 electrodes per array distributed across 96 threads.” The coauthors of the paper also noted that Neuralink has performed at least 19 surgeries on animals and successfully placed wires about 87% of the time. During the presentation, Musk hinted that Neuralink has worked with primates. “We definitely need to address the monkey in the room. This is a sensitive subject,” he said. “A monkey has been able to control a computer with its brain.” https://venturebeat.com/2019/07/16/neuralinks-technology-embeds-tiny-wires-in-the-brain-to-read-electrical-pulses/ https://www.documentcloud.org/documents/6204648-Neuralink-White-Paper.html
  9. Okinawan's start off almost half the level of DHEA and Testosterone (if I remember correctly) than Americans but it declines much more slowly. Eventually, Okinawan's end up with higher testosterone levels at older ages. Last time I had my testosterone checked it was 412 ng/dl about 2.5 years ago (I'm 35 in Oct). So I guess that's pretty low for my age... Some Okianwan's might be doing CR, some not. Many of us here are doing CR intentionally and are a lot more strict about it than Okinawan's. As for the Rhesus monkeys, the results were inconsistent in many ways with what is observed in mice, rats, and humans. There were no differences in fasting glucose for some of the groups in the NIA study (especially for females) or it took until they were over 20+ years old for them to diverge. In humans, both males and females have significantly lower insulin and glucose (as we see in mice). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3832985/ CR females having *higher* triglycerides than the control group (total opposite of what we see in humans). I could go on and on but this has been covered so many times. I highly recommend you check out Michael's post on it over at SENS. There's actually some data in mice or rats (wish I could find it..) where they show that castrated males live longer than intact males. Males who were given estrogen have significantly longer lifespans, even longer than female mice and females that were given estrogen. Females that were given testosterone lived the shortest. Low testosterone (in ad lib, poor diet, population) correlates with CVD. But we are not them... I'm sure you've seen the results of Fontana's studies on people of the CRS, we are not getting CVD. We are not getting Diabetes. And we aren't having issues with too much fat (for sure). We actually have some good data on individuals here. We're not just stats or hypotheticals, we're real people, doing real CR, showing real results that are contrary to the data you're presenting and we have low testosterone. From the study Dean cited: "Interestingly, out of the 81 eunuchs, three were centenarians, aged 100, 101, and 109 years. The current incidence of centenarians is one per 3,500 in Japan and per 4,400 in the United States. Thus, the incidence of centenarians among Korean eunuchs is at least 130 times higher than that of present-day developed countries." https://www.sciencedirect.com/science/article/pii/S0960982212007129

    CR sleep ... some useful tips at last!

    I usually fall asleep really fast and have no trouble staying asleep. I've been listening to ASMR before sleep and it's actually kind of nice and relaxing lol. Makes me super relaxed in fact...

    CR Wikipedia page..

    I checked out the Wiki page on calorie restriction today. Haven't seen it in a long time. It just struck me as overall pretty negative. And cites Spindler from 2010 that the long-term effects of CR are unknown. It seems to ignore most of the work done at WUSTL, Biosphere 2 and CALERIE. Would be good if that page got an update... https://en.wikipedia.org/wiki/Calorie_restriction I thought I remembered it being much more detailed than that? Or maybe not?
  12. "In this study, lower total testosterone levels were associated with central obesity and established CVD risk factors including insulin and insulin resistance, glycemia, lipid profile, and blood pressure as well as emerging risk factors such as leptin, adiponectin, IL-6, and CRP" Which is basically the complete opposite of people who are on CR. We're probably not going to be dying from cardiovascular disease. I think that testosterone accelerates aging in men and that perhaps in some people there is a 'net benefit' whereby it's protective against diseases that will kill them earlier than any effect less testosterone might have on the intrinsic rate of aging. If you're on CR and have very minimal risk of some of the main causes of death, a higher level of testosterone is probably not beneficial. I still think it's hard to extrapolate these findings from the general population onto someone who is doing CR, it needs to be contextualized to some extent. It's a bit like Michael Rae's thoughts on the DHA accelerated aging hypothesis, where a higher intake of DHA may accelerate aging in animals (and humans) on CR. But perhaps if you have a very high risk of cardiovascular disease and autoimmune disease like Lupus, then maybe DHA might save you from early death and it's a 'net benefit' for you.
  13. Talks at Google Published on 12 Jul 2019 Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why its absence is so damaging to our health. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive. Professor Matthew Walker discusses with Matt Brittin twenty years of cutting-edge research to solve the mystery of why sleep matters, how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime -- this is a talk that will change how you think about bedtime! Moderated by Matt Brittin.
