Keeping an Older Metabolism Young
by author Brad J. King, MS, MFS

Let’s face it–most of us never worry about our metabolisms when we are young. In youth, metabolism is at its peak, and the body has a greater natural ability to burn fat and remain lean.

Unfortunately, as we age, our metabolic rates naturally declines. We lose our lean metabolically active tissues, accumulate more body fat, and lose muscle mass. This is why we may weigh the same in our later years as in our teenage ones, even though things certainly don’t look or feel the same. Much of the earlier us has been replaced with a softer mushier us.

But research indicates that we don’t have to experience a decline in metabolic activity with age–if we do the right things.

Don’t Lose It–Move It

We can’t blame our age-related metabolic decline solely on lost muscle. It turns out that younger people seem to have a higher metabolism than older people, even if they have the same amount of muscle. Studies indicate that age-related metabolic decline is intricately linked to how active we are and how much we eat throughout our lives.

Research published in the American Journal of Physiology in 2001 compared two groups of healthy, sedentary men (young and older) with two groups of physically active men (young and older). After factoring in the amount of lean body mass for each subject, the researchers discovered that metabolic decline is only related to reductions in exercise volume and energy intake. It does not occur in older men who are able to exercise and eat at a level similar to that of young, physically active men.

Men are not the only ones who can benefit from exercising at a higher intensity and eating more. Research from the University of Colorado showed that the age-related metabolic decline seen in sedentary women is not observed in women who exercise regularly.

Start Slowly–Choose Wisely

Before you decide to run a marathon or eat enough food to make you explode in an effort to enhance your aging metabolism, let’s get a few things straight. If you have never exercised or if you only exercise once in a while (a.k.a., Weekend Warrior Syndrome), start off slowly and work your way up to a higher intensity.

Secondly, in order to boost your aging metabolism, it is imperative to consume the right foods, including high-quality protein (grass-fed beef, game meat, free-run poultry, organic eggs, fish, and whey), essential fats (nuts, seeds, flaxseed oil, fish oils, and krill oil), and fibre-rich carbohydrates (vegetables, fruits, and whole organic grains).

The take-home message is simple: You can boost a slagging metabolism at any age with the right exercise and a proper diet. All you have to do is make it happen.

Running the Risks: Running vs Walking
There is no simpler or more natural workout than walking. It's easy, inexpensive and a great way to get in shap.

Running and Your Health
Do you love the feel of running in the great outdoors yet worry about the bad press running sometimes gets? You can continue to enjoy running as long as you alternate this activity with other types of exercise and take certain precautions.

Walk On
Walking - everybody's doing it! In fact, millions of North Americans have adopted walking as their main form of exercise. Walking is popular because it can be enjoyed just about anywhere.

Diversify for Fitness
If you've been faithfully logging miles in your jogging shoes and wonder why you are not getting fitter-or why you are not getting fitter faster-you may need to diversify your training. Improving your fitness requires challenging yourself by changing your routine occasionally.

Run for Your Life
You could look better, feel healthier, improve mood and self-confidence, sleep like a baby, reduce stress levels, boost energy, protect your heart and cardiovascular system, increase bone density, sharpen your vision...and all you need is a pair of running shoes. Sound too good to be true? Not so!

Take a Hike!
Hiking offers a cardiovascular workout that burns up to 400 calories an hour, calms the mind, and nourishes the spirit. The body is pleasantly relaxed, the mind lets go of trivial worries, and the beauty of the natural world reawakens the spirit.

Move It or Lose It
Aging is inevitable. It is possible, however, to curb many of the effects of aging with regular physical activity. We all want to maintain quality of life and good health as we age, and exercise is essential to maintaining good health. The less we move, the more susceptible we are to various conditions and diseases, and thus the vicious cycle of inactivity begins.

Walking: The Ultimate in Fitness Freedom
Elizabeth was looking for a way to reduce stress, depression, and anxiety and achieve a heightened sense of well-being. She told me she hates going to the gym or swimming pool and is looking for another form of exercise to help her reach her fitness goal.

All It Takes is 10,000 Steps
Have you heard about Shape Up America's 10,000 Steps Program? Supported by the 2005 Healthy Living Strategy here in Canada, the program recommends that we strap on a pedometer to measure whether we're walking enough for good health.

I Walk; Therefore I am
More than 2,000 years ago, Hippocrates told his patients, "Walking is the best medicine. In the 18th century Thomas Jefferson pronounced, "Walking is the best possible exercise.

Extreme Frisbee
Had enough of playing Frisbee with your dog? Want to toss that disc with people who, like you, love the exhilarating feeling of pushing their bodies and working as a team? Then, ultimate Frisbee may be the sport for you.

Take a Hike!
As a child I loved to wander the hills surrounding our home in rural Pennsylvania. Today, preparing for a day hike up Chinese Mountain on Quadra Island, I get that same feeling of wanderlust as I pull my backpack from the closet and fill it with hiking gear and food.

Step Out with a Pedometer
How many steps do you take in a day? Studies show that Canadians take an average of 3,000 to 4,000 steps a day, and according to Health Canada, that's too few.

One Step At a Time
For some of us, the idea of starting a fitness program can be daunting; there are so many different exercise options to choose from. But we all do something every day that, when harnessed into a purposeful fitness regimen, can do wonders for our overall health and well-being.

Nordic Walking
My wife and I love to take a walk after dinner every evening, usually along the shores of Vancouver's False Creek inlet with mugs of tea in hand. Perhaps tonight we'll set down our tea and instead pick up a pair of lightweight Nordic walking poles for our stroll.

Swim, Bike, Run
Triathlon was introduced in the 1970s in California and migrated north into Canada soon thereafter. Some 50,000 Canadians participate annually in these continuously timed competitions, which feature segments in three of the world’s most popular sports—swimming, cycling, and running.
