Older adults are used to hearing that a natural part of the aging process is that our metabolism will slow down; the metabolic rate is the rate at which our bodies burn calories in order to keep our vital systems functioning and allow us to do the things we do on a regular basis. As we age, most of us find that slowly but surely our weight increases; it seems that as our metabolic rate decreases (assuming everything else stays the same, like exercise and diet) the pounds begin to add up. We are just not burning calories at the rate that we used to.
An article in Science, reports that our assumptions are actually incorrect. Our metabolism is not slowing as we get older simply because we are aging, but rather because a number of other factors come together to decrease our levels of activity. Leading a more sedentary lifestyle due to work, home responsibilities, technology–and even the pandemic–is behind those decreasing metabolic rates.
A recent article on http://www.cnn.com, explains the issues and concludes that this research is good news for older adults. If aging is behind our decreasing metabolism, then there is nothing we can do to reverse its effects; we are simply stuck in a downward spiral. What the research shows is that we actually have it in our control to maintain and increase our metabolism as we get older.
The article suggests four main strategies:
- Be active throughout the day. Many of us spend hours at a time at a desk (or on a couch) with little movement. Even little bursts of activity throughout the day can raise metabolic rates.
- When you exercise, do the right types for maximum metabolic effect. HIIT exercises are recommended because they raise the metabolic rate and keep it elevated even after the workout is over; check out my blog post on HIIT for more info. Additionally, strength training (working with weights and other types of resistance) has a similar effect.
- Make sure to get enough protein in your diet and keep hydrated. The simple act of eating increases our metabolic rate because it takes calories for the digestive system to do its job; consuming proteins (especially after a workout) can help to build muscles which cause us to burn more calories. Drinking water–aside from its other positive assets–can raise our metabolic rate too.
- Get plenty of rest. Not sleeping enough can lead to a myriad of health problems. Allowing our bodies to adequately refresh and re-energize can help counteract the negative effect of these maladies. It is recommended that adults get at least 7 hours of sleep each night.
Metabolic rate decreases are not a done deal as we age. There is much we can do to counteract the effects of being sedentary, not exercising enough, eating a poor diet, and being overtired. It is all in our power–not part of some process beyond our control. This is good news indeed!
