Eat early today?

A simple study, which is my favorite kind. Also, 7 other things worth knowing today.

Sometimes I come across a cool new health study, and it makes sense, but I'm leery of promoting it too hard because—well, because this isn't exactly my field.

So take this one with a grain of salt (wait, not salt; that's not so great for you).

With that caveat, a group of scientists out of the University of Texas Southwestern Medical Center say their experiments on mice suggest changing the way you eat— moving your meals earlier in the day—could have a significant effect on longevity.

How much of an impact? Well, they found that cutting calories and/or feeding mice during the hours of the day when they were most active correlated to significant additions to their normal two-year lifespan.

• Reducing calories correlated to a 10 percent increase in lifespan.

• Feeding them only at night—when mice are most active —correlated to a 35 percent longer lifespan.

• Doing both added nine months to each mouse's life on average, which works out to about 37.5 percent increase in longevity.

As the Howard Hughes Medical Institute, a nonprofit medical research group reviewing the study put it:

For people, an analogous plan would restrict eating to daytime hours.

The research helps disentangle the controversy around diet plans that emphasize eating only at certain times of day, says [Joseph] Takahashi, a molecular biologist at the University of Texas Southwestern Medical Center.

Such plans may not speed weight loss in humans, as [another] recent study in the New England Journal of Medicine reported, but they could prompt health benefits that add up to a longer lifespan.

See what I mean? This study was published recently in the respected, peer-reviewed journal Science, but I don't claim to be anything other than an interested amateur.

Still, I get excited about these kinds of studies because they seem promising, and because the fulfill one of Bill's Keys to Self-Improvement: They involve changes that are easy to make—or at least simple—meaning it's much more likely that I'll actually stick with them.

Tell me to make doctor's appointments as early in the day as possible and I'll make a practice of it. Tell me I should drink more coffee and it's like: yep, already doing it.

Making a conscious effort to shift at least for some sizable percentage of calories? It also seems doable.

Helpful, and perhaps related: If you were to tell me I could only eat one meal a day for the rest of my life, it would be breakfast—maybe more like brunch, actually, since I make the rules. No question.

Anyway, I find as I get a bit older that I'm willing to consider changes that might eke out a few extra years for me here on this Big Blue Marble.

It's funny; when you're 20 I don't think you see much difference between the notion of living into your 70s versus your 80s or 90s or even later. They all seem so far away. and, they are.

But now that I'm past 50, I see the difference. So, if that means changing some of my worst habits, like eating stupidly too late in the day, it’s worth the shift.
