It's a common knowledge that we need to work harder to keep our body fit as we age. One major reason is the inescapable biological fact that metabolism slows as we age. Inescapable for now, at least, until medical technology finds some safe way to alter it.
Genetic research into aging is trying to do just that. Several studies in the last two decades have pointed to hints about precisely what causes aging. If they get sufficient knowledge of the subject, there is some hope of altering the situation.
Until then, there are several things we can do to stay fit and healthy as we age. Healthy diet and exercise are, without any doubt, the most important elements for older people.
For some, working out an hour per day - a five mile run, a long swim, hitting every station on the weight machine - is still feasible. Others will have to adjust their routine to what is realistic for their own circumstances. Don't ignore the signals that will help guide you to do that. Mild discomfort is to be expected, especially the day after a vigorous workout. Extreme pain is a sign of something is wrong.
As we age there's a greater temptation to indulge in tasty, but high sugar, high fat foods. We see it as a reward for all the years of hard work and dietary discipline. Unfortunately, we pay a higher price later in life for those than we did in our 20s or 40s.
An occasional dessert is actually healthy, both for your state of mind and the sugar and fat. Both are essential compounds in moderation, though simple sugars are preferable to complex, and unsaturated fats are preferable to saturated. Sugar is essential to generating the energy needed for all biological processes. Good fats help regulate hormones, neural processes and other vital activities.
Staying active is equally as important as proper diet. A good walk helps keep the cardiovascular system in working order. Mild stress on the muscles and joints keeps them lubricated and firm. Both muscle mass and bone density reduce dramatically in sedentary individuals.
Studies show that a sedentary 65 year old will have (on average) only 60% of the aerobic capacity of a 30 year old. Those who do no strength training lose muscle mass equivalent to seven pounds per decade. But those statistics are not written in stone. Exercise can help improve them tremendously.
Studies at various universities carried out for 25 years show that runners who continued to train kept almost all their capacity of 20 years previous. Those who engaged in resistance training maintained muscle mass equal to that of ten years earlier. Use it or lose it.
A person who has been idle, but suffers no debilitating disease, can reverse their odds. Start slow and think long term. Pain from overdoing it is one of the leading causes influencing people not to stick with it. Take long walks, then work up to more vigorous activities under the guidance of a professional.
Live a long and healthy life, not just a long one.
