Aging and Exercise

Time dictates so many aspects of our lives. When beginning this article, I thought to myself how much time controls my day from the seconds, minutes, and hours. And of course in relation to this piece of writing, it is the measure of our age. The aging process is unique to each of us. But ultimately, it does impact our life decisions, and that includes our exercise choices. So let’s take a look at the relationship between aging and exercise.

Naturally, activity level changes when we get older. As one of my long time clients put it, “Man, I don’t just roll out of bed anymore ready to go”. This isn’t to say that one is less motivated, rather, the energy expenditure levels are different. This is mainly due to the fact that, “A major fraction of total daily energy arises from resting metabolism, and it is thus important to note that resting metabolism decreases with aging, by about 10% from early adulthood to the age of retirement, and a further 10% subsequently.” (1) Adding to this, “One reason is the loss metabolically active muscle mass and parallel increase in metabolically inert depot fat. In later old age, there may also be some overall reduction in cellular metabolism.” (1) When muscle mass decreases, this can cause body fat to increase. Keeping the excess pounds off can get harder. As such, “Your body fat can increase by up to 30 percent, which leads to a loss of lean muscle tissue and can affect your sense of balance. This can make it difficult for you to perform exercise activities you once enjoyed.” (2)

We need to continue a strength training program in order to not let our bodies replace muscle with fat at the rate it would like to. Not to use a scare tactic but here you go: “Strength peaks around 25 year of age, plateaus through 35 or 40 years of age, and then shows an accelerating decline, with 25% loss of peak force by age of 65 years.” (1)

Exercise becomes so extremely important as we grow older. We tell ourselves that we used to be able to eat whatever we wanted and still look fabulous, but now the odds aren’t necessarily the same anymore. We have to take care of our bodies, and we can help prevent certain diseases with exercise. For example, “Your bone mass begins to decline once you enter your thirties, putting you at risk for conditions such as osteoporosis. If you are concerned about developing this condition, perform more weight-bearing exercises, such as running and tennis. Regular cardio activity will also help you control high blood pressure and high cholesterol, as well as ward off type 2 diabetes and some kinds of cancer.” (2)

As I always say, there is no can’t. That word is not allowed in my studio. There are modifications for so many exercises, and I will be by your side as we run, walk, or crawl to get it done. If we don’t use it, we lose is, right? Not every day is a peak performance day, but we do we can. As long as we are active, we are being productive to our bodies. Running a marathon might not be in the future, but what about making to your training session twice a week and keeping that commitment to your body? Goals should be realistic. Remember the glory days fondly, but know that you are keeping your mind and body in better condition and sticking around longer for your family and friends by maintaining an exercise program. Fitness is a way of life and the destination involves progress not perfection so just keep going one rep a time, one day at a time, and with every age of your life.

Stop Sitting: It’s Time to Take a Stand!

We probably know that sitting can be bad for our health. In fact, sitting has been called the “new smoking.” So, if you’re laid out on a couch, or plopped in a chair right now, you might have the most common health problem in America today — Sitting Disease. That might sound silly, but prolonged sedentary living plays a substantial role in a lot of the health concerns of our time.

The U.S. is a world leader in sloth. Seventy-five percent of the population of the United States fails to meet even the minimum government recommendation for daily exercise. And latest statistics shows that the highest rates of inactivity remain among those ages 65 and over. This epidemic is not confined to any region of the United States either. It is ubiquitous in both rural and urban communities and both the wealthy and the poor. (1) (2)

Chronic diseases are major killers in the modern era, and physical inactivity is a primary cause of most of them. Depressing, huh! Well, it doesn’t have to be a death sentence. Increasing our physical activity can result in substantial increases in both the number and quality years of life. Adults who are physically active are healthier and less likely to develop many chronic diseases than adults who aren’t active — regardless of their gender or ethnicity.

Physical activity/exercise is also the primary way we can slow down biological aging, as well as prevent or delay premature death from 35 chronic conditions, including: low cardiorespiratory fitness, obesity, type 2 diabetes, coronary heart disease, hypertension, stroke, depression and anxiety, osteoporosis, osteoarthritis, balance, bone fracture/falls, many cancers, erectile dysfunction, and pain. (3)

Get Up and Move

It’s time to take a stand! Get on your feet and out of the computer-typing, cell phone using, freeway-driving position you find yourself in all too often.

Of course, it can be tough to schedule time to exercise when you want to see the hottest thing on Netflix, there’s Haagen-Dazs in the freezer; actually, if you’ve got anything better to do with your time. For a lot of us, the most pressing question about exercise is: How little can I get away with?

It turns out, doing anything is better than doing nothing. This means you can get the same health benefits as people who work out in a gym but spend the rest of their time sitting. Staying active throughout the day results in similar benefits to doing a rigorous workout.

We can reverse three to four decades of inactivity by performing easy, bodyweight, multi-joint movements that use more muscles. Even doing twice-a-week leg exercises strengthens them. And small gains in leg strength make a big difference in everyday life. It can get easier to get out of that chair, climb stairs, and carry groceries. Incorporating exercises for leg strengthening into your regular workouts may also aid in fat loss. And you’ll improve your balance. (4)

So, What’s the Drill?

Most government guidelines define physical inactivity as anything less than 150 minutes of walking or moderate physical activity per week. Physical activity is anything that gets your body moving — not just traditional exercise. The process of adding activity to your busy life can be difficult, but it can be done. Even lifelong exercisers had to start somewhere.

150 minutes each week may sound like a lot of time, but the good news is you don’t have to do it all at once. You can meet this goal by breaking it into smaller chunks of time during the day to. Take a 10-minute brisk walk and repeat it three times a day, five days a week. By adding structured, planned, intentional movement to your days, you can reap additional life benefits, increasing the health of your heart and lungs, improving muscular and bone strength, and increasing flexibility. (5)

Look for ways to be active that are fun and work for you. My vision is to guide you to live, work, and play actively, no matter your age, where you live, or your ability.

The (Current) Truth About Vitamin D

There are more health claims made about vitamin D than perhaps any other vitamin.  Media stories touting vitamin D for this ill or that are common, particularly in the age of COVID-19. We’re also frequently told Americans don’t get enough vitamin D, with surveys showing as many of 40% of individuals have below optimal amounts in the blood. So how do we get vitamin D and what claims are true and backed by research?  Let’s take a closer look at vitamin D to flesh out what we know for sure and where more research is needed. 

What is Vitamin D and How Do We Get It?

Molecularly, vitamin D is a group of fat-soluble compounds with a four ringed cholesterol backbone. What’s most important to know is that it comes in two forms — as vitamin D2 in food and as vitamin D3 in our skin.

Vitamin D3
Our skin is our primary source of vitamin D, but it begins there as an unorganized and inactive form, requiring UV exposure to convert to usable vitamin D3. Conversion via UV light is exceedingly efficient, and it’s estimated brief exposure of the arms and face is equivalent to ingesting 200 international units day. Conversion varies however with skin type (darker skin converts more), latitude, season and time of day. Infants, disabled persons and older adults often have inadequate sun exposure as well, and the skin of those older than 70 also does not convert vitamin D as effectively. Interestingly, vitamin D also requires temperature to be activated, so you may not get as much of a benefit from sunlight in the winter months as you might expect.  

Vitamin D2
Because it is fat-soluble, dietary vitamin D2 is best absorbed with fat in the diet and fish is a common source. Uptake can be negatively impacted by disorders associated with fat malabsorption such as celiac disease, Crohn’s disease, pancreatic insufficiency, cystic fibrosis, short gut syndrome and cholestatic liver disease.

Vitamin D in the Body: What We Know It Does

Once activated and in the bloodstream — either by UV exposure or absorption through the diet — the liver converts vitamin D to 25-hydroxyvitamin D (25[OH]D), and then the kidneys further convert it to 1,25 hydroxyvitamin D, the most active form of vitamin D in the body. For this reason, kidney and/or liver problems can also negatively impact vitamin D levels.

Interestingly, all cells in our bodies have receptors for vitamin D, and this has in part fueled the varying claims as to how it might impact health. What we know for certain is that it helps with calcium absorption in the gut, regulating calcium levels via the kidneys, and regulating parathyroid hormone. Vitamin D’s role in calcium regulation and absorption means it has a direct impact on healthy bone growth and turnover. For this reason, you often see it in calcium supplements.

Research has also shown a clear correlation between Vitamin D and muscle health, including research showing improved lower body strength. Some research has also shown vitamin D can help prevent falls in the elderly.

Notable Areas Where the Jury is Still Out

  • Vitamin D has been thought to lower the risk of cancer, but currently, there is insufficient evidence to support this, though there are many ongoing studies.
  • There is also insufficient evidence showing that vitamin D helps improve autoimmune conditions and respiratory conditions such as asthma, COPD and acute viral respiratory diseases.  In a large study from the UK, no association was found between vitamin D levels and risk of mortality from COVID-19.
  • Although low vitamin D levels have been associated with an increased risk of cardiovascular disease in some studies, there is no evidence that vitamin D supplementation improves cardiovascular outcomes.
  • Similarly, a growing number of trials examining the effects of vitamin D supplementation on pregnancy and birth outcomes show conflicting results, with some showing reduction in risk of low birth weight, but more data is needed.

4 Simple Ways Your Fitness Routine Can Benefit from Self-Care

When you think of taking care of your health, exercise is one of the first things that comes to mind. You know you need to stay active and stay in shape to protect your body, but what you may not realize is that you also need self-care to protect your mind. Combining self-care and fitness is the best wellness move you can make. Here are some ways to do it.

Start Working Out More at Home

Sticking to your fitness goals is important. If getting to the gym causes you stress or interferes with your schedule, though, you may want to think about building a gym at home. It’s easier than you think, and can make getting those daily workouts in easier on your schedule. You can use any extra space you have, whether it’s your garage, a spare room or a basement, and quickly set up a workout space in your home. The equipment you fill it with will hinge on your needs and the amount of space available, but for most people, basic workout equipment, like a jump rope and dumbbells, is enough to get a good workout at home and stick to their budget.

Consider Holistic Wellness Practices

A regular fitness routine will help keep your body in shape. Working out can help enhance your mood as well, but it’s not really enough to manage your mental health. You also need to find ways to help your body recover after all that effort, which is where holistic self-care practices come in handy. Incorporating practices like acupuncture, Pilates, massage and chiropractic treatment can be beneficial for relieving stress and helping keep your emotions in balance. Yoga is another practice that complements most physical fitness routines, and it improves strength and flexibility in your body. Runners can use beginners poses such as downward facing dog and pigeon to help build more muscle and keep joints flexible, all while reducing stress.

Treat Pain Through Self-Care and Exercise

If you suffer from chronic pain, you can combine self-care and fitness to find relief. The trick is to find simple workouts that get your body moving while helping your mind feel calm.

Yoga is also a good choice here, but you can also try doing tai chi. This slow, intentional practice is especially effective for seniors looking to decrease pain symptoms and decrease their fall risk.

You can treat more than arthritis with exercise and self-care, though. Studies have also shown that regular physical activity can help Alzheimer’s patients, and exercise may even play a role in preventing this debilitating condition. Research around this is still limited, but one thing that’s for sure is that adults who exercise are less prone to other chronic health conditions. Heart disease, diabetes, and certain cancers can all be prevented with the right fitness routine.

Help Yourself Age Well with Fitness and Self-Care

Older adults who are looking to stay in their best shape also need to factor self-care into the equation. Without self-care, you are leaving your body and mind vulnerable to the effects of chronic stress. Consistent levels of high stress can leave older adults struggling with heart disease, anxiety and other health issues. Staying active is a great way to care for your well-being, but you also need to make sure you are taking time to really enjoy life. Practicing daily mindfulness can help all adults live more fulfilling lives. Being mindful means taking time to pause and reflect on your life, and to be thankful for the things that make you happy. In between workouts, take a 15-minute break to meditate or to write down what you’re grateful for.

Physical fitness can go a long way in preserving your overall health, but it’s not the only wellness habit you should commit to for a better life. Finding ways to work self-care into your fitness routine and your everyday life can change your body and mind in many positive ways, so make time for more self-care, and keep working toward those health and fitness goals.

How the Human Body Changes As It Ages

The human body undergoes a lot of changes during its lifetime. From infancy to old age, there are biochemical processes in the body that define these changes.

Some of them are visible externally, such as the greying of hair, skin becoming less supple, etc.

But beneath all of this, some processes happen to make all of this possible.

Once You Lose Weight, Can You Keep It Off?

“I lost 10 pounds and vowed to keep them off, but no such luck. I’m so discouraged.”

“I reached my goal weight, then BOOM, I regained it once I stopped dieting.

“This is my 3rd time losing 40 pounds…”

If any of those stories sound familiar, you are not alone. Research suggests dieters tend to regain lost weight within five years, if not sooner. This includes many fitness exercisers and athletes who struggle to stay at a goal weight.

If you are fearful of regaining your hard-lost weight, this article will help you understand why maintaining lost weight takes effort. Paul MacLean, PhD, Professor of Medicine & Pathology at the University of Colorado School of Medicine, has carefully studied weight regain. He notes three reasons why dieters regain weight: biology, behavior, and environment.

Biology: The body has a strong biological drive to regain lost weight, as noted with increased appetite and a slowed metabolic rate. As backlash from dieting, the body learns to store fuel very efficiently as fat.

Behavior: After three to nine months, dieters tend to be less strict with their low-calorie diets; they often report they have hit a weight plateau. Despite self-reported claims they are diligently dieting (yet only maintaining weight), these dieters can become discouraged and less adherent. (Note: Diligently dieting anecdotes are hard to verify.)

Environment: We live in an obesogenic environment with easy access to ultra-processed foods, a sedentary lifestyle, and chemicals that contribute to weight gain including those found in upholstered furniture, pesticides, cosmetics, and who knows where else. Weight is far more complex than self-induced over-eating and under-exercising!

When adding on exercise, some people lose weight and some gain weight. Exercise alone does not guarantee fat loss. Exercisers who lose weight tend to keep the weight off if they stick with their exercise program. High levels of exercise are linked with greater success. That’s good news for athletes who train regularly! That said, a fine line exists between compulsive exercisers (who exercise to burn off calories) and athletes (who train to improve their performance). Fear of weight gain can impact both groups.

Questions arise:

  1. Is weight maintenance more about being compliant to a restrictive eating plan than to exercise?
  2. Do those who comply with a strict diet escape weight-regain?
  3. Are exercisers more likely to stay on their diet?
  4. Does exercise create metabolic adaptations that favor maintaining lost weight?

Research with rodents

Finding answers to these questions is hard to do in humans because of biology, behaviors, and environment. So MacLean turned to studying formerly obese rodents who had lost weight by being put “on a diet” and then were allowed to eat as desired for 8 weeks. Some weight-reduced rodents stayed sedentary while others got exercised.

  • Fancy cages accurately measured the rodents’ energy intake and energy expenditure. MacLean was able to see how many calories the rodents burned and if they preferentially burned carbohydrate, protein, or fat for fuel.
  • The exercise reduced-obese rodents ate less than the sedentary rodents and they regained less weight. Exercise seemed to curb their drive to overeat, meaning they felt less biological pressure to go off the diet. With exercise, their appetites more closely matched their energy needs.
  • Exercise promoted the burning of dietary fat for fuel. Hence, the exercised rodents converted less dietary fat into body fat. They used carbohydrate to replenish depleted glycogen stores. Note: Carbohydrate inefficiently converts into body fat. That is, converting carb (and also protein) into body fat uses ~25% of ingested calories to pay for that energy deposition. To convert dietary fat into body fat requires only ~2% of ingested calories. Given the calorie-burn of exercise plus the metabolic cost of converting carbs into body fat, the exercised rodents regained less weight.
  • The sedentary rodents ate heartily and were content to be inactive. Their bodies efficiently converted dietary fat into body fat; they used carb & protein to support their limited energy needs. They easily regained weight.

The Depressing News

When followed over time, the longer the rodents were weight-reduced, the stronger their appetites and drive to eat got. When allowed to eat as desired, they quickly regained the weight. “At least people, as compared to rodents, can be taught to change their eating behaviors to help counter those biological pressures,” noted MacLean. For example, people who have lost weight can stop buying fried foods, store snacks out of sight, limit restaurant eating, etc.

More depressing news. Most of MacLean’s data is from reduced-obese male rodents. Exercised males showed less weight regain than did exercised females. The female rodents seemed to know they needed extra energy to exercise, so they ate more and regained weight. MacLean states we need more research to understand the clear differences in the biological drive to regain weight.

A glimmer of hope

The best way to maintain weight is to not gain it in the first place. Yes, easier said than done (as stated upfront), but at least athletic people who maintain a consistent exercise program can curb weight regain. We can also change our behaviors to minimize weight regain by prioritizing sleep, curbing mindless eating, and choosing minimally processed foods.

Ideally, the sports culture will change so that athletes can focus less on weight and more on performance. It’s time to acknowledge that athletes, like dogs, come in many sizes and shapes. Some athletes are like St. Bernards, others are like Greyhounds. A starved St. Bernard does not become a Greyhound, but rather a miserable St. Bernard.

By fueling your genetic body type and focusing on how well you can perform, you can enjoy being stronger, more powerful—and likely can still meet your sports goals. When being leaner comes with a life-long sentence to Food & Exercise Jail, you might want to think again?
