Dynamic Aging

Once I hit 50 I started to think about aging a lot more.

What kind of life do I want to be living when I’m 75? When I’m 85? Will I live to be 95?

There is a lot of research around this. The field of “longevity” is very popular right now.

There are two angles to this…some research looks at “mortality” and others look at quality of life and incidence of disease.

I think both are important.

There are a few things that have become quite clear overall from research. One is that consistent, moderate physical activity is good for anti-aging and living a longer life. (1)

Regular physical activity appears to reduce the overall mortality rate by more than a quarter and to increase the life expectancy by more than two years compared with the sedentary population’s average.

Another is that sleep is very important for quality of life (in particular relating to dementia) and poor sleep habits can contribute to disease and early mortality. (2,3)

And we know that social interaction is key to living a longer, healthier, happier life. (4)

The research around nutrition is a lot more convoluted. But we do know some things.

Protein absorption declines as we age (we absorb and assimilate less protein from the food we eat). (5)

Protein is important for maintaining muscle, skin, and bone health (and pretty much everything else). So, it makes sense that we have to pay attention to protein intake.

As we age, muscle mass is a better predictor of mortality than body fat percentage. I will repeat that.

As we age, muscle mass is a better predictor of mortality than body fat percentage.

We have learned that muscle is protective and body fat matters less and less the older we get (except for those people with extreme highs and lows of body fat). (6,7)

People who eat more polyphenol-rich food seem to be protected from many of the diseases associated with aging (8) and have an easier time maintaining their weight. (9) And polyphenol-rich foods help protect lean muscle mass as we age. (10)

So, what are the takeaways?

If you want to experience “dynamic aging”, which means aging feeling strong, active, and happy, I recommend doing the following things:

  • Be active every day, aiming for at least 30 minutes of concentrated movement daily
  • Do strength training 3 times per week
  • Eat enough protein for your body size
  • Eat polyphenol-rich foods at every meal
  • Give yourself at least 7-9 hours of sleep opportunity each night
  • Be kind to yourself as often as possible
  • Understand your needs for social interaction

Dynamic Aging

Some notes about the above list:

  1. There is a “sweet spot” with exercise. Exercising too much or too little are both bad. You don’t have to go crazy with working out. Even just 30 minutes of walking, 5 days a week can make a world of difference to your health and your aging process. You could also do gardening, take a swim, ride a bike, or play with your dog. All of that stuff is really good for you!
  2. Strength training is essential for slowing down the inevitable gradual but persistent loss of muscle we all experience as we age. Do not skip the strength training! And be gentle to yourself in the process. You can slowly build up your strength. Injuries can put a screeching halt to progress so be careful and ideally work with a fitness professional.
  3. The goal for protein is .6 to .8 grams of protein per pound of your target body weight. If you weigh 200 pounds but you feel your best at 170, then use that as your target. In that case, you would multiply 170 x .6 for your minimum amount of protein. That comes to 102 grams of total protein from all sources per day! The more strength training you do, the higher your protein needs will be. So if you are consistently training 3-4 times/week then increase the amount to .8 grams of protein per pound of your target body weight.
  4. All plant-based foods contain polyphenols (which are magical plant nutrients that have all kinds of benefits). Some contain more than others. Some of the big wigs include coffee, matcha green tea, extra virgin olive oil, red onions, strawberries, capers, parsley, celery, radicchio, garlic, and turmeric. There are many more!
  5. There is also a sweet spot when it comes to sleep. The goal is 7-9 hours of sleep per night. Once you go below 6 and above 10 you are almost guaranteeing long-term trouble. Poor sleep is a contributing factor to many chronic diseases. The most notable is dementia! So good sleep is crucial for healthy aging! And remember that just because you are in bed, it doesn’t mean you are sleeping. Those numbers are for actual sleep. If you take a long time to fall asleep or wake up a lot, you are getting less. I recommend giving yourself 8-9 hours of “sleep opportunity” each night for optimal sleep amounts.
  6. I hope I don’t have to convince you to be kind to yourself. But I probably do. We beat ourselves up in so many, many ways. And it’s quite insidious. Even just trying to be healthy and live your best life can be a subtle form of not being kind to yourself (pushing yourself too hard to eat a perfect diet for example). Here is a podcast episode about this that I think is particularly important to listen to.
  7. Loneliness kills us. We need social interaction and that can range from a short chat with a neighbor or the check-out clerk at the grocery store to long deep conversations or hugs from loved ones. We need some of all of that!
  8. In order to promote optimal wellness and dynamic aging, we need social interaction and if we don’t get it and we feel lonely, it can increase our risk for depression (11), metabolic syndrome (12), mortality (13), high blood pressure (14), dementia (15), pain, and fatigue (16).

So, there you have it!

The basics of aging healthfully, gracefully, and with pleasure!
