Maximizing life expectancy/enjoyment
Ignoramus20526 wrote:
After returning from obesity to normal weight (223/177/180) due to a eat no crap/eat less/exercise more approach, I am now thinking about health in general. What I would like to know is, what are the things that a person can do to maximize their life expectancy/enjoyment of life via various natural means (no meds). I want to be clear that I want the maximum life expectancy multiplied by enjoyment of life. So any regimen that makes me live longer but makes me miserable is not something that I would like to consider. I will appreciate references to some non-kooky books that do not advocate spending money on programs affiliated with their authors. I am not interested in having an "extreme body", squatting 500 lbs, etc etc. However I am interested in being fit, agile, strong, and flexible. My current thinking is that the cornerstone of such an approach is doing lots of low intensity aerobic exercise such as walking, plus calisthenics based strength training. Another cornerstone is staying within the normal weight interval. The third cornerstone is eating only natural and healthy food, according to some definition. To me it means eating no heavily processed foods and no sugar. The fourth is to have a stable life and to not work too much. I am aware that there is some scant evidence that living on calorie restricted diet (1500 or so calories per day all the time) also can help one live longer. But smoehow I have a feeling that such a life is either impossible or not satisfying to me. Right now I eat about 1900-2000 calories per day, walk 100 minutes per day, and my weight is relatively stable for the last 3 weeks. I can live on that but not on much less, I think. Does anyone have any comments or book suggestions? i Mice live *twice* as long in captivity if they are given only half as much as they would eat ad libitum. Not only do they live longer but they a physically more active in their older age. Imagine humans doubling their lifespan to 150 years and playing tennis when they are 120 years old. -- Dr. Andrew B.

You certainly have an active imagination. There is no objective evidence that caloric restriction in humans would have the same effect as in mice. I thought there was some evidence that periodic fasting was advantageous, prompting the body to go into a repair cycle. But maybe that was just speculation regarding studies on mouses.

However there's good evidence that it will extend our lives - since it has done so in practically every other animal tested. -- __________ |im |yler http://timtyler.org/ Remove lock to reply. |

Tim, Isn't there an issue concerning *when* and *how* the individual starts their CR regimen? IANAE, but I've heard that this is a tricky point; it's the thing that most concerns me about 'adult-start' CR... Ph. |

Perhaps we need to sit down next to one of those 114 year old guys and write down everything he does. Ask him if he's keeping his lifts up? Bill |

You certainly have an active imagination. There is no objective evidence that caloric restriction in humans would have the same effect as in mice. There is no objective evidence that it won't. 1) That is not how science proceeds though! Hypothesis thence evidence to disprove or lead to refinement of the hypothesis. Science proves nothing (every schoolboy knows - Bateson) as you should know Doc! 2) There are countless thousands of drug trials that theoretically and clinically worked well in animal subjects but did not make it through human trials due to mechanisms and confounding factors in humans not present in the animals. 3) Outside medicine proper, there is no objective evidence that God does not exist or that there are no purple kanifs on the planet that might be circling Betelgeuse. And any of an infinite number of such hypotheses. But science does not proceed (see 1) by trying to prove negatives. That said, a reasonable extrapolation could be made based on the evidence of calorie restriction in certain animals as long as "AOTBE" strictures are observed. |

There are a host of other factors that affect lifespan. Aneuploidy alone will be a limiting factor! I think you may be a bit too narrow in your extrapolation of results of caloric restriction in animals to lifespan increases in humans. Way too narrow. -- Dr. Andrew B.
