According to Harvard researcher and longevity expert Dr. David Sinclairgrowing older – as we know it – could actually be optional. Or at least a lot more flexible than we have been led to believe.
We often equate growing older with vulnerability, forgetfulness and fatigue. But that’s chronological obsolescence: the number on your driver’s license. Biological aging, on the other hand, determines how your body and brain actually function. And here’s the good news: your biology is much more influenced by your lifestyle than by your genetics.
Let’s break it down.
Chronological age versus biological age
You’ve probably seen it before: two people of the same age who seem to live in completely different bodies. One is active, lively and radiant. The other… not so much. That’s the difference between chronological and biological age.
Although your date of birth is fixed, your biological age can speed up (or slow down) depending on your habits. So what can we do to stay younger for longer?
Here are a few habits that science (and Dr. Sinclair) say actually make a difference.
- Reconsider your diet
No one likes the word “diet,” but your food choices have a huge impact on how your body ages.
Mostly food plant-based diet with little sugar, with periods of fastingIt has been shown to reduce inflammation, improve metabolic function and lower the risk of age-related diseases. Besides, your the skin can look younger without cosmetic treatments.
And yes, feeling a little hungry every now and then can be a good thing. Intermittent fasting gives your cells time to rest, repair and regenerate. You don’t have to go into full monk mode, but giving your body longer breaks between meals can help slow the aging process from within.
- Move your body – in every way possible
Movement is medicine- and you don’t need a gym membership or a 6-day lift split.
Dancing in the kitchen, walking around the block or even gardening counts. Regular exercise improves heart health, increases energy and helps maintain muscle and bone mass, both of which naturally decline as we age.
Bonus points for strength training (think resistance bands, bodyweight exercises, or even carrying groceries). Muscles aren’t just for looks, they’re protective.
