Sex is a favored way to make babies. There is some interplay between reproduction, repair, and longetivity. In fact, worms live much longer when food is scarce and they put a hold on reproducing. And typically, what applies to worms applies... (more)
I think you are going to find actual sex has less of an effect than the levels of sex hormones because human culture is so weird. There is ample evidence that men with very high testosterone levels die earlier, though there are some confounding... (more)
I've been camped out around 12% for a while and through experimentation have found what choices make me a little leaner or a little less lean, so I'm confident I could camp out at 10% or so, but that decision would be based on narcissism, not... (more)
I don't know about optimal body fat for health and longevity, but I know my goal was to get under 25% and now that I've been eating Paleo for a few months I'm hovering around 20-22%. It is absolutely perfect FOR ME. I like the way my body looks... (more)
I was reminded the other day about the section in GCBC regarding Cynthia Kenyon's research linking carbohydrates and longevity (that is, at least for C. elegans). Adding glucose to C. elegans' diet significantly reduced its lifespan via an... (more)
Aging, and health, are not related to caloric restriction per se. It is related to nutrient sensing hormones and pathways that caloric restriction effects that in turn greatly influences genetic expression towards a longevity phenotype. The same... (more)
In Michael Rose's talk (about his Methuselah flies and what they mean for longevity) at the recent Immortality Institute conference in Brussels, he talked about the three diet regimes that humans have lived under: Hunter Gatherer (2.5M years(?),... (more)
Lithium (Li) is a trace mineral, used in the treatment of bipolar disorder at doses hundreds of times higher than that from diet. The main dietary sources are vegetables and grains, followed by dairy. The concentration in water varies widely:... (more)
I know this question is kind of odd, but... I really want to know and I hope somebody here on Paleohacks knows the answer. I always wanted to know what was Creme Puff's diet, but never was able to obtain a verifiable source. I know she ate... (more)
Whether or not it's Paleo, it's consistent with other evidence that high-fat low-protein moderate-carb is good for longevity.
Professor Cynthia Kenyon, whom many experts believe should win the Nobel Prize for her research into ageing, has discovered that the carbohydrates we eat ??? from bananas and potatoes to bread, pasta, biscuits and cakes ??? directly affect two key... (more)
There are no real long-term studies on this, but thankfully there are dozens of Arctic tribes that ate a low-carb high-fat diet. We have the Inuit, Saami, Athabaskans, Eveny, Nenets, Itelmen, and Koryak peoples for example. It's a diverse... (more)
Dr Leila Denmark has recently died at the age of 114. A remarkable woman she was still working as a pediatrician at the age of 103. http://en.wikipedia.org/wiki/Leila_Denmark Apparently she refused cake at her 110th birthday party claiming she... (more)
i think a big aspect people often forget about when it comes to longevity is mental health and social health. diet obviously plays a role but its not the be all and end all in living for a long time.
I stumbled across this article on Facebook via one of the relatives of this Thousand Oaks, CA woman who just turned 107. Imagine my paleo delight when I read the phrase (bolded below) about bacon grease. Haha. Does anyone else stumble across these... (more)
I have watched a very interested program by the BBC (link below), it covers various methods of sub-calorific and intermittent starvation, fasting, IGF1 and aging, also the effect on cancer and heart disease. As ever a very entertaining and... (more)
What are the main differences in how someone processes glucose from the diet vs gluconeogenesis? Paul Jaminet, a seriously smart cookie and charming guy, writes we need a certain number of grams of glucose a day and can create it through... (more)
I am into living the healthiest life I can, while I'm here. If it prolongs my life, so be it...but that isn't my goal. I am looking for intense quality not quantity. I can't wrap my mind around why people want to live for as long as possible,... (more)
" Reduced glucose availability promotes formation of reactive oxygen species (ROS), induces catalase activity, and increases oxidative stress resistance and survival rates, altogether providing direct evidence for a hitherto hypothetical concept... (more)
Living the paleo life will hopefully put my on track for a long healthy life, which got me thinking - taking everything into account... what could that realistically be? Starting with genetics: looking at my grandparents. One grandmother died aged... (more)
Can eating paleo modify our epi genome making us younger as we get older? in worm studies, caloric restriction reduces insulin to increase lifespan. In Paleo man carbohydrates and not calories are restricted but because the hemoglobin A1c levels... (more)
Loreen Dinwiddie is allegedly a 108-year-old vegan who has been vegan since 1922. Is she lying, lucky, or is veganism not that bad? How can a body function after 90 years of guaranteed B-12 and DHA deficiencies, not to mention probable... (more)
There's a lot more to health than nutrition Stress management Sleep Genetic / Epigenetic considerations Regarding DHA deficiencies, it isn't a foregone conclusion that vegans or vegetarians in general will be deficient - perhaps not... (more)
While thinking along the lines of the human species as a whole, doesn't it make sense that death of a person after say... 30-35 years of age (after raising offspring) would be optimal? That a shorter lifespan would be optimal for our species as a... (more)
I have heard it from a couple people in the paleo community that longevity is tied to muscle mass. Can anyone expand on this? If this is the case I might try to bulk up.
Numerous animal studies have shown that restricting calories promotes a longer lifespan. But chronic caloric restriction lowers your muscle mass, and increased muscle mass is also tied to longevity (discussed in a previous thread). So if I want to... (more)
A previous PaleoHacks thread ties health and longevity to muscle mass, i.e. more muscle mass means a longer and healthier life. Brad Pilon and others have said that there is a genetic lean muscle mass "set point" that determines how much skeletal... (more)
What resources or thought leaders do you reccomend to learn about epigenetics, nutrition for longevity and nutrigenomics?

I'm seeing a lot of advocating for "eliminate, then reintroduce" science in the paleosphere lately. While I think that it is a good approach for determining what foods a person has a sensitivity too, I think it is a terrible method for finding the... (more)
