    Off Wiki:

    What do you guys think of this??
    Do you suppose it would be healthier if we just ate (Energy intake) to match our energy outtake? Or a little less?
    This looks like the most credible way someone might go about in making there lifespan longer....

    I know its mostly in the genes that decide your longevity but I do know that genes act on enviormental or other triggers so I suspect the food we eat is one.

    I am diabetic type 1 so atleast ill be using less insulin but what do you guys think? Calorie restriction with optimim nutrition seem like the smartest idea? What makes us want to eat so much..... just our evolutionary instincts?

    I've read this kind of stuff on carbohydrate restriction, but not general calorie restriction. I.e only eat carbohydrates in proportion to your energy requirements, to the point where none gets put away as fat.

    I read in a magazine today that rats survive 50% longer on a calorie restricted diet than regularly fed mice.

    Something about free radical production, insulin, etc. I guess the question is even if it did work significantly how many people would exchange food for a longer life

    You will need to spend a lot more time eating - like at least 6 meals a day, all very low calorie as in vegetables. Salad mostly.

    You will lose your sex drive and ability pretty quickly, but will have many more years to remember what it was like, if you have had a sex life already.

    You may have a harder time recovering from what we call a "hit", like a serious illness or an accident.

    Other than that though, you can lose a lot of weight pretty rapidly with extreme calorie restriction, though this has no yet been proven to work in humans for life extension.

    Lose sex drive? I read it would increase cognitive capabilities, etc. I thought it would actually benefit the endocrine system.

    I know it hasnt been proven but Im just wondering why we eat so much.

    I tried restricting more than I do now, mainly because I'd like to be thinner.

    The food cravings and fatigue drove me nuts, and so I decided I'd rather eat to maintain my current weight.

    Try doing a search on SIRT1 gene, also protein restriction...from what research has been done in this direction, the caloric restriction alone does not seem to slow cellular aging, it also requires some reduction in protein intake as well...not a drastic amount.

    Re: the salad?
    For at least eight months I was on a roughly 1500-calorie diet...you either eat a lot of salad and cooked veggies on that or you're freaking starving.
    You eat bulk or nothing, in other words. Stoni's right.

    The thing that interests me about the whole caloric restriction idea...is not so much life extension as health extension.
    I have to croak, and prolonging that for a few years isn't worth starving every damn day...but not being decrepit or senile for a decade before death? That's worth a little effort and deprivation.

    P.S. In your case though? I'd stop smoking...If you wish to indulge... make tea out of the stuff sweetened with raw honey.
    It tastes good, plus you can use the stems that way too.

    Using a vaporizer would work well too. Inhaling smoke is bad for you.

    A recent Science News article on the Mormon ritual of a once - monthly 24 hour fast indicates it may well be a habit worth taking up. They have a much lower rate of heart attack and stroke than the rest of us, also much reduced rates of type 2 diabetes. Scientific speculation is that it is that fasting that does the trick.

    Today, SN has an article that states adopting a ketotic diet like the Atkins Diet for a period of time can reverse kidney and eye damage from type 2 diabetes by resetting the involved genes. Not a long term weight loss solution, but effective in the short run for weight loss as well as addressing kidney and eye damage.

    link to that article:

    The philosophy is very simple, the lesser you stress and strain the system the longer it will last.

    Excess calories are a strain but you have to eat enough calories that your proteins are not diverted for energy use [body uses protein when carb intake is not optimal, fat stores take time to be broken down so the preference is carb>protein>alcohol>fat]

    Plus you have to eat enough that the body does not go into starvation mode or else your basal metabolic rate will drop and you will gain weight and lose stamina at the same level of energy intake.

    Plus you have to ensure that you eat "healthy" ie cover all your micronutrient requirements otherwise the hunger pangs will drive you nuts.

    Stoni. Fasting is a good idea. Unfortunately I'm a type-1 diabetic. (Diagnosed at age 22 adult on-set) so its not reccomended I fast (the doctor says there might be a chance I can hold on to my pancreas beta cells longer if I eat?)

    But yeah I mean like straight calorie restrictino with optimum nutrition. The only thing putting in my body should be healthy and very limited in carbs and I should only eat like once or twice a day or a bunch of very tiny meals.

    Im trying to think of ideas on how to decrease my insulin thanks sam to you to. I tend to eat alot more protein and fat than carbs my "carb intake" (as of lately) is lower than 50g's a day.... which is equivlent to like a soda or two.

    It might make you live longer, but who wants a life like that??? I'd rather have a shorter life with more pleasure.

    Remember, all of this health advice might not make your life any longer, but it will sure feel like it!

    You keep saying this Frag, and you have a lot of company too. You do not have to lose weight or take up exercising, we love you anyway.

    For the rest of us though, it helps to talk about these different ways to get healthier and improve our health situations as we struggle with our own independent life goals.

    Do not forget that as much as you enjoy not exercising I enjoy exercising. It is OK with me if I am a rare type in this time.

    Oh yeah - I enjoy the heck out of my life too. Columbia Crest H3 Cabernet, Godiva's dark chocolates, a 1973 Les Paul DeLux Custom, a workshop that others would kill to have and the absolutely finest Lady Labrador in the whole wide world!!!!

    Also remember, I live with my wife, and she is hot and almost as healthy as I.

    Type 1 diabetics can't do what other what other people do dietetically and have it benefit them...not at all.

    Diabetics should eat frequent little balanced meals, lean protein, low fat, a little complex carbs, the more complex the better...in fact, I'd recommend carrying around a little pack of benefiber tabs to eat with whatever else you eat.
    Benefiber is made of inulin.

    For better blood sugar control, avoid the hell out of refined sugar. Use the fake stuff, stevia, or xylitol.

    NEVER drink sugar-containing beverages unless you're going into a hypoglycemic crisis or something-that stuff hits your bloodstream like a bomb.

    Check religiously.

    The American Dream . That "Les Paul" I think you should give that to someone who knows how to play it like Me. Dust collecting for axes like that is forbidden you know . It will make you die before your time.

    There is a society that starve them selves for a living. Can't remember the name of it. They are a bunch of skinny scronny people. They do live longer than the norm . The theory is a natural survival instinct kicks in and causes you to live longer. That is kind of how the society explains it

    Type 1 and type 2 are different beasties...
    Type 2 would actually benefit from caloric restriction.

    I seem to remember reading that type 1 is likely to actually be caused by genetic predisposition plus a viral agent somehow causing pancreatic damage?

    Type 2 is caused by insulin resistance-your muscles are resistant to the hormonal "message," so to speak...so your pancreas puts out more insulin...this can result in hypoglycemia...and the pancreas, in theory, eventually gets won out from years of working too hard and overproducing insulin.

    Reversal of the process can be effected through diet, exercise, weight loss, and supplementation-to a degree. Exercise and chromium picolinate seem to help decrease insulin resistance. Complex carbs and fiber supplementation avoid sugar spiking-pectin, cinnamon, glucomannan, and guar gum, if I remember, have all been shown to be helpful in patient trials...they all also help decrease appetite.

    But a type 1 diabetic has trouble staying out of ketoacidosis, trouble keeping weight on, tends to be more of a management problem and is insulin-dependent.

    I know a type one diabetic. Three of my grandparents were type 2 diabetics, I don't want to be one...so I'm a bit of a health nut.

    old people can't eat that much since the metabolism slows down anyways or they can but it's going to hurt them more. unless one is physically active, it's not healthy to eat the same amount of food people did at a younger age. people have to adjust their diet not only according to lifestyle but age.

    I don;t think that keeping a check over your calories is a restriction.Two things that you need to consider always is that eat what ever you want to eat but eat healthy and the second thing is that do consider Total calorie count per day.Yes,there are few studies that have proved that It helps to increase the Human age...

    None of mine gather dust, though I do try to spread the love around amongst them.
