#2. Fasting and Longevity

Friday, September 07, 2018

I just read about a study done (on mice) by scientists from the NIA (National Institute on Ageing) that links fasting to longevity. It was reported in yesterday's edition of USA Today.

The findings showed that mice who ate one meal per day, and thus had the longest fasting period, seemed to have a longer lifespan and better outcomes for common age-related liver disease and metabolic disorders.

"We think what's going on is when you stop eating for X-number of hours, your metabolism goes into standby mode. Your body fixes and removes all the garbage during this time." "When the next feeding comes, you are better prepared for the energy you're about to consume.”

The belief is that when you continuously eating, or snacking periodically throughout the day, your metabolism doesn’t have time to readjust or rest.

The scientist also said that there were no obvious negative side effects to the rodent fasting, and that the mice who chowed down once a day lived up to 40 percent longer than the ones that had access to food around the clock.

i am a big fan of scientific studies - but I also have lived long enough to be skeptical of new findings until they are reproduced by other studies. Also, findings that are specifically about nutrition and diet seem to be popular one year, and then are refuted a couple of years later.

However, the findings from this study seem to support what I remember as findings from an earlier study about a correlation between severe calorie restriction and longer life.

Personally, food ls such a source of pleasure for me, that I remember at the time wondering why anyone would want to live a long life if they could only eat such a limited amount of food.

(LOL. Well THAT statement certainly explains why I'm here on Spark People, doesn't it!!?!!)

Anyway, I do often eat only two meals in a day. It works for me. As a retiree, I don't eat breakfast much earlier than 9. Then, I eat the second meal anywhere from 3 to 4 -- the earlier, the better. I try not to eat anything after 6pm; it's just too late.

My friend, Janet suggested that sticking to daily routines would help me to stay on track -- and she is so right. Maybe I will try to stick to the routine of only two meals a day, no matter what I am doing that day.

We'll see how that works.

    It is good to find what works for you! We're all an experiment of ONE.

    Thanks for the shoutout!
    I'm eating my "retiree" breakfast right now at 10:30 am. I can't eat before exercise and am not hungry anymore until later in the morning.
    I'm planning to have a sit-down with my bestie SIL as we are vacationing together soon. She's also on a life-change eating plan and I'm hoping we can come to agreement on meals on our trip. Working around the 2 men in our lives who run on autopilot in restaurants and grocery stores has me concerned about all the things which will come back to the condo.

    Worth an experiment! (I too wondered about the point of longevity if you are miserable and food deprived and hungry-grumpy the whole time!) I eat 3 meals daily, but I don't snack. So 'fasting' between 7pm and 7am... Though I am asleep much of that time!

    Intermittent fasting is something I've just recently been experimenting with. Seem to have settled in for 16:8 with my meals between 11 a.m. and finished by 7 p.m. at the latest. I've pretty much eliminated my snacking over the past year or so and my years long issues with low blood sugar seem to have pretty much resolved to my amazement.

    I do intermittent fasting and it has really helped me. I am like you though and don't rely on studies as they are not using the scientific method.

    Routine is good for me, too, although I eat more meals in a day than you are thriving on. Breakfast, lunch, dinner, and one or two snacks, depending on the day and what else is going on... spread out across the hours. Like you, I try to shut down the kitchen after supper, which is usually before 6 p.m.

    Major goal? To *feel good*... and by that I mean being healthy.
