Strategies for Energetic Aging
By Susan M. Kleiner, PhD, RD
THE PHYSICIAN AND SPORTSMEDICINE- VOL 26 - NO. 11 - NOVEMBER 98
Getting older can mean you're getting better. At 40, 50, or 60, you probably know more, work smarter, and have more confidence than when you were 20. But no one wants to feel old.
To minimize the pitfalls of aging, you can't just sit back and "grow old gracefully." Making changes in your diet and exercise routines may be your key to staying active and vital well into old age. (See "A Checklist for Energetic Aging," below.)
Exercise is Essential
Until recently, weight gain and declining physical ability were mostly blamed on aging. We now know that much of this decline starts with inactivity. This leads to loss of muscle mass and increased weight, and eventually to disease and loss of independence.
Most of the calories you consume are burned by your muscles, so if you don't exercise to maintain muscle mass, your body will burn fewer calories. If you continue to be active, you maintain muscle mass, aerobic capacity, and fat-burning potential, and you keep your weight down. At the same time, you reduce your risk of developing many diseases. This will help you continue to be active into your seventh and eighth decades, and even beyond.
General Diet Strategies
When you stay active you can eat more without gaining weight, which means you can get more of the nutrients that help preserve health. Here are some helpful diet strategies:
Maintain a healthy weight. Obesity has been linked with increased death rates from many types of cancer. To help maintain a healthy weight, you may want to try changing your pattern of eating. A study at Tufts University in Boston found that postmenopausal women who ate fewer than 1,000 calories per meal burned fat at virtually the same rate as younger women. But with larger meals of 1,000 calories each, the older women's ability to burn fat was greatly reduced. And when dietary fat is not burned as fuel, it is stored as body fat.
To improve your burning of fat, then, try eating four to five smaller meals rather than three large ones each day. Besides helping you with weight control, smaller, more frequent meals and snacks will also provide energy throughout the day.
Keep your fat intake low. No more than 20% to 25% of your calories should come from fat. High-fat diets increase the risk of heart disease and cancer. Avoid foods high in saturated fats like fried foods, chips, desserts, high-fat meats, and full-fat dairy products, dressings, dips, and sauces.
Fill up on fiber. Fiber keeps food moving through your system. It decreases your risk of constipation, diverticulosis, and hemorrhoids. It can help lower your cholesterol level and remove carcinogens.
Eat a plant-based diet. If your diet consists mostly of fruit, vegetables, grains, and plenty of protein-rich beans, nuts, and seeds, it will almost certainly be low in fat and high in fiber. In addition, you'll be eating foods that are high in antioxidants and phytochemicals--natural substances that may help prevent cancer and slow some aging processes.
Four Vitamins and a Mineral
The following nutrients become increasingly important as you age:
Folic acid. Folic acid, or folate, helps prevent heart disease and stroke by limiting the blood level of an amino acid called homocysteine (high levels of which are linked with an increased risk of cardiovascular disease). If you eat a diet rich in fruits, vegetables, and beans, you should be getting enough folate. But if you want to make sure, take a supplement with 400 micrograms of folic acid. Beware though! Too much folic acid can mask evidence of a vitamin B12 deficiency.
Vitamin B12. Insufficient stomach acid (atrophic gastritis) inhibits the separation of vitamin B12 from food. This condition occurs in 10% to 30% of people over age 60, and may cause a vitamin B12 deficiency. To prevent the problem, a daily supplement containing 25 micrograms of vitamin B12 is recommended. B12 also helps limit homocysteine levels.
Vitamin E. Vitamin E has been linked to lower risks of heart disease and prostate cancer. An antioxidant, it also may help decrease inflammation that occurs after strenuous exercise in people over 55 years old.
Since vitamin E is fat-soluble and found primarily in vegetable oils, nuts, and seeds, low-fat diets are notoriously deficient in this nutrient. Make sure to include some of these foods in your diet. A 100- to 400-IU supplement is also recommended. If you have high blood pressure or take coumadin or other medicines that prevent blood clots, check with your doctor before taking these supplements--vitamin E may raise the risk of stroke and interfere with the action of the drugs.
Vitamin D. Vitamin D deficiency accelerates bone loss. Between 30% and 40% of adults over 50 may have a borderline or pronounced vitamin D deficiency.
Milk and fortified breakfast cereals are good sources of vitamin D. Though your skin makes vitamin D when exposed to sunlight, older skin can be up to 50% less productive.
Recently, the National Academy of Sciences recommended daily vitamin D intakes of 200 IU for ages 50 or younger, 400 IU for ages 51 to 70, and 600 IU for ages 71 and older. Most older people don't get enough by sun exposure, so if you don't get enough in your diet, you need to take a supplement.
Calcium. In clinical trials, people given calcium or calcium plus vitamin D had fewer fractures than people given a placebo. Women aged 19 to 50 and those aged 50 to 64 who take estrogen need about 1,000 mg a day; women older than 50 who are postmenopausal and not taking estrogen should consume 1,500 mg per day. Men aged 25 to 64 should consume about 1,000 mg daily, and those older than 65 need about 1,500 mg daily. You can get enough calcium from three to four servings of low-fat milk, yogurt, or cheese each day, or from fortified foods or supplements.
Our thirst mechanism gets worse as we age. That means you need fluids, but your body can't tell you. If you take medications it is essential to stay well hydrated.
Drink at least eight 8-ounce cups of noncaffeinated, nonalcoholic fluids every day, and one to two 8-ounce cups of water or a sports beverage before you exercise. During exercise, especially in the heat, drink 4 to 8 ounces every 15 minutes, and at least two 8-ounce cups after exercise.
Aging With Advantages
We know more today than ever before about the influence of diet and exercise on the aging process. Take advantage of that knowledge, take action, and you'll increase your chances of staying healthy and strong for many years.
A Checklist for Energetic Aging
When combined with a good exercise program, these nutrition habits and strategies will help you stay healthy and active well into old age:
Maintain a healthy weight; smaller, more frequent meals may help.
Keep your fat intake low.
Fill up on fiber.
Eat a plant-based diet.
Get enough minerals and vitamins, especially calcium, folic acid, and vitamins B12, E, and D.
Drink at least eight 8-oz glasses of noncaffeinated, nonalcoholic fluids daily.

I am 42 years old. So I'm at the age where I have begun to be think about aging related issues. And Dr. Kleiner is absolutely correct that as we age a careful attention to exercise and diet is vital. Below are some of my thoughts in this regard.
Benefits of Strength Training
I am powerlifting again, which, of course means strength training. And strength training is the best form of exercise there is to prevent the loss of muscle mass that Dr. Kleiner mentions. In fact, even those of us in our 40's or older can actually gain muscle mass as we age if we lift weights.
It was in order to re-gain weight I had loss due to my health problems that I began lifting weights again in July of 2002. And in the 14 months since then I have gained almost 12 pounds. The training I utilized in doing so is outlined in the article From Scratch to World Records.
Increasing ones muscle mass will also increase ones metabolic rate. So in addition to the calories burned while exercising, strength training will increase the number of calories one burns 24/7. As indicated in the article Diet Evaluation, I am now consuming about 2200 calories a day. This is a rather high amount given that I only weight about 120 pounds.
Strength training is also the best form of exercise to prevent osteoporosis. This was mentioned in last issue's article Proper Performance of the Powerlifts. That article also mentioned that performing the powerlifts would increase the functional ability of senior citizens.
It should also be noted that these benefits are best realized using free weights not machines. A while back I read about a study that looked at two groups of senior citizens. One group began using free weights while the other used Nautilus equipment. After six months, both groups increased the amount of weight they were using for their respective exercises by about 30%. However, only the group that was using free weights increased in their functional abilities, i.e. their ability to perform day-to-day tasks. The Nautilus group actually loss about 5% of their functional ability.
And another study looked at ten 70-something men who were living in a nursing home. They were doing so not because of any serious health problems but simply because they were too feeble to take care of themselves. The researchers had them start a strength training program centered around the three powerlifts (squats, bench presses, and deadlifts). A year later, all of the men had improved so much in their functional abilities that they had moved out of the nursing home and were living in apartments by themselves.
I apologize that I don't have the specific references for these studies. But I believe I read about them some time ago in different issues of Physical magazine (published by GNC).
Moreover, I know first-hand that weight training can increase ones functional ability. At the worse of heath problems, I was unable to care for myself. But weight lifting helped me to begin functioning normally again and to get my life back.
As for gaining muscle mass, I worked out with Nautilus equipment for about three years in the late 1990's. When I began I weighed about 112 pounds. After the three years my weight was up to 117 pounds. So the Nautilus training helped me to gain five pounds in three years. However, as indicated above, with free weights I've gained almost 12 pounds in a little over a year.
As for osteoporosis, a recent TV newscast on my ABC station reported about a study that compared different types of exercises. The study concluded that "weighted squats" were the best exercise for preventing osteoporosis. And this makes perfect sense. With squats, you're holding the weight on your back and balancing it with your arms. So your entire skeletal frame is supporting the weight. And this stress on the skeleton promotes bone thickening.
Now this is to not to say that aerobic exercise is not important. However, as we age, strength training is actually more important than aerobic exercise. So continue to perform some aerobic exercise, but be sure to include strength training, preferably with free weights, in your training routine.
Diet and Supplements
Diet is important at any age but even more so as we age. As Dr. Kleiner indicates, one problem is that as we age we tend to need less calories. And with a lower consumption of calories it gets difficult to attain sufficient nutrients. However, as she correctly indicates, exercise, especially strength training, will increase our caloric requirements. Hence, we'll be able to consume more food and thus have more opportunities to consume sufficient nutrients.
Dr. Kleiner also points out the importance of eating frequent small meals each day rather than one or two large ones. Such an eating pattern also increases the metabolic rate. It is for this reason that I fully endorse and advertise Optima Bars on my Fitness for One and All Web site. These bars are a convenient and nutritious snack and thus make it easy to eat several meals a day. An Optima Bar can serve as one of the day's "meals." I use them in this fashion quite frequently.
I found it somewhat surprising that Dr. Kleiner actually recommend the taking of supplements as she often seems against doing so. But maybe even she realizes that it can be especially difficult for older adults to attain the needed amounts of nutrients from food alone. And in this, she is correct. It is for this reason that I use Jarrow Formulas Multi 1-3. This is a high-quality yet rather inexpensive multiple vitamin-mineral formula. It contains all of the nutrients Dr. Kleiner recommends that older adults supplement with..
However, one point that I might now disagree with Dr. Kleiner is in her recommendation to eat a plant-based diet. I say "now" as I made the same recommendation in my book Creationist Diet. At the time that book was written I was following a vegan diet (i.e. a diet that includes no animal foods of any kind, not even dairy or eggs). However, I now believe that following such a diet contributed to my health problems.
Don't get me wrong here. I still stand by most of what I wrote in my book. And I still recommend eating copious amounts of plant foods like the ones that Dr. Kleiner mentions. But this does not preclude eating healthy forms of animal foods, like lean meats, skinless baked chicken, fish, yogurt and other low fat dairy foods. For more in this regard, see Creationist Diet Preview.
Moreover, I couldn't image trying to powerlift without eating moderate quantities of animal foods. I even use egg and dairy based protein powders in order to attain sufficient quantities of protein for muscle building. See Protein Powders for details.
It is possible to age gracefully, without the loss of functional strength and health that many experience. But this requires a commitment to exercise on regular basis and a careful attention to diet. Supplements can also aid in this regard.
I know that in my own case, these three factors, exercise, diet, and supplements, have helped me greatly in overcoming my health problems. So now, at the age of 42, I feel like I am in the best shape I have been in since my 20's.
