Have you ever heard someone complain that their metabolism slowed down in their 30’s? Or reminisce about when they were younger and could eat whatever they wanted without it affecting their shape?
It may sound like common thinking that our body’s metabolism begins to decline as we age; however, new research has started to challenge this long-held belief.
Metabolism, the rate at which your cells convert food into energy or storage, can be thought of by how easily our bodies gain or lose weight. Genetics, body composition (muscle mass), physical activity, drugs or medication, and diet all play a role in determining your unique metabolic rate. But, what about age? Does it actually slow down during middle-age?
A recent study from Duke University is redefining the relationship between age and metabolism. According to the study, the metabolism remains relatively stable from age 20 through 60 and then steadily decreases annually.
So if metabolism doesn’t begin to wane until our 60’s, why do so many of us experience the well-reported middle-age slowdown and associated weight gain? What can be done?
A mix of behavioural and lifestyle changes happening at once is more likely why. But let’s take a look at an area of cause we specialize in.
As early as age 25, we begin to lose muscle mass every year unless we specifically combat this ageing process known as Sarcopenia. Sarcopenia is a function of the use it or lose it principle. If you don’t routinely stress (strength train) your muscles, your body is programmed to lose them over time which negatively affects your metabolism.
Being strong, not just when we are young, but throughout life is the secret to maintaining your youthfulness. Muscle loss leads down a path of weakness and inactivity, constraining the need for a revved-up metabolism.
Good news - as an active member of the Body by Jojo community, you are already fortifying against any perceived, or real, metabolic slowdown. Routine strength training is the weapon of choice in the fight against age-related muscle loss and its downstream effects i.e. decreased metabolism.
Just keep doing what you’re doing. Your coaches will take out the guesswork, so all you have to do is show up, focus on working hard, and your body will take care of the rest.
Be strong and be well!
