Get Motivated to Get and Stay Fit

Colberg ADA Workplace Photo 2You may have started the new year out with the best of intentions to increase your fitness and better manage your diabetes by exercising regularly. If you have diabetes or are at risk for developing the disease, deciding to commit to fitness could be a real lifesaver. That’s why it’s more important than ever that you make sure this decision sticks. Here are some motivational tips for getting started being more active.
Check Your Blood Glucose: When you start a new exercise, checking your blood glucose before, sometimes during, and after your workout pays off. A reading that changes — especially in the direction that you want it to — can be very rewarding and motivating. If you don’t check, you may never realize what a positive impact you can have on your diabetes simply by being active. For example, if your blood glucose is too high after you eat a meal, and you want it to go lower without taking (or releasing) any more insulin. You can exercise after your meal and bring your blood glucose down within two hours after eating and taking insulin, or you can avoid or lower post-meal spikes.
Start with Easier Activities: Start slowly with easier activities and progress cautiously to harder ones. Exercising too hard right out of the gate is likely to make you end up discouraged or injured, especially if you haven’t exercised in a while. If you often complain about being too tired to exercise, your lack of physical activity is likely what’s making you feel sluggish. After you begin doing even light or moderate activities, your energy levels rise along with your fitness, physical condition, and mental health.
Pick Activities You Enjoy: Most adults need exercise to be fun, or they lose their motivation. It’s human nature to avoid doing the things you really don’t like to do, so try to pick activities you truly enjoy, such as salsa dancing or golfing (as long as you walk and carry your own clubs). Having fun with your activities lets you more easily make them a permanent and integral part of your diabetes management. If you haven’t found any that you enjoy much, choose some new ones to take out for a test run (so to speak).
Spice It Up: It’s essential for motivation to mix your workouts up with different activities. People commonly complain about exercise being boring. Feelings of boredom with your program can be the result of repeating the same exercises each day. To make it more exciting, try different physical activities for varying durations and at different intensities. Knowing that you don’t have to do the same workout day after day is motivating by itself.
Have a Plan B: Always have a backup plan that includes other activities you can do in case of inclement weather or other barriers to your planned exercise. For example, if a sudden snowstorm traps you at home on a day you planned to swim laps at the pool, be ready to walk on the treadmill or substitute some resistance activities. You can always distract yourself during your second-choice exercise to make the time pass more pleasantly. Read a book or magazine, watch your favorite TV program, listen to music or a book on tape, or talk with a friend on the phone while you’re working out.
Get an Exercise Buddy (or Several): You don’t need to go it alone when being active. Having a regular (and reliable) exercise buddy increases your likelihood of participating, and it also makes your activities more social and fun. Get your spouse, family members, friends, and co-workers to join in your physical activities, regardless of what time of day you do them. Having a good social network to support your new or renewed exercise habit helps you adhere to it over the long run.
Schedule It: Put your planned exercise down on your calendar or to-do list like you would other appointments. You show up for your doctor appointments, so why should scheduling your physical activity be any different? Never make the mistake of assuming it’ll happen just because you claim that you want to do it a certain number of days per week or month. It takes some planning ahead and the commitment to make it a priority.
Set Goals and Reward Yourself: Setting goals helps keep your interest up. For instance, if you walk for exercise, you may want to get a pedometer and set a goal of adding in 2,000 more steps each day. Break your larger goals into smaller, realistic stepping-stones (such as daily and weekly physical activity goals) for all your active lifestyle changes, and use SMART goals. Trackers, activity logs, and other motivational tools are also widely available online. Tip: Reward yourself when you reach your exercise goals (but preferably not with food).
Get More Spontaneous Physical Activity: You don’t have to work out at a high intensity to help diabetes and weight management. You can also add physical movement all day long doing anything you want to, including gardening, housework, and many other spontaneous physical activities. For instance, if you have a sedentary desk job take the stairs rather than the elevator whenever you can. Walk to someone else’s office or the neighbor’s house to deliver a message instead of relying on the phone or email. Or park your car at the far end of the parking lot and walk the extra distance. Guess what? You’ve just gotten yourself more active without giving it much thought.
Take Small Steps: If you get out of your normal activity routine and are having trouble getting restarted, simply take small steps in that direction. You may need to start back at a lower intensity by using lighter weights, less resistance, or a slower walking speed. Starting out slowly with small steps helps you avoid burnout, muscle soreness, and injury. Even doing only 5 to 10 minutes at a time (rather than 30 or more) is fine. After you’re up and moving, you may feel good enough to exceed the time you planned on doing in the first place. The key is to begin by any means possible.

Exercise to Lower Your Risk of Dying (Prematurely) with Type 1 Diabetes

Bob Stewart Jumping (crop)Much of the research on length of life for individuals living with type 1 diabetes is pessimist, which makes a new study released recently a breath of fresh air. Data were collected for the ongoing nationwide, multicenter, Finnish Diabetic Nephropathy (FinnDiane) Study that tracked the death rate of 2,639 study participants for an average of 11.4 ± 3.5 years (1).

In this study, participants’ leisure time physical activity was reported via a self-report questionnaire. Importantly, their physical activity and its intensity, duration, and frequency were examined related to dying from all causes and from cardiovascular events; some of these adults with type 1 diabetes already had diabetic kidney disease.

The researchers also looked at potentially confounding factors like sex, how long people had been diagnosed with type 1 diabetes and how old they were when they got it, as well as physical measures like their systolic blood pressure, triglycerides (blood fats), BMI (body mass index), and HbA1c (a measure of overall blood glucose control over two to three months).

The conclusions of this study came as no surprise to me: exercise is associated with a lower risk of premature death from cardiovascular or any other cause in adults with type 1 diabetes. Overall, 270 people died during the follow-up period, 127 of whom had kidney disease. Only exercise intensity was associated with cardiovascular mortality, with intense activity being best for preventing early death from cardiovascular events. Both how much total physical activity they got and how frequently they exercised were associated with a lower risk of dying from any cause. Prior studies have shown that exercise frequency may also matter in preventing such events, with a higher frequency of physical activity lowering the risk (2).

People with type 2 diabetes have already been shown to have a lower risk of premature death when they are physically active (3); this is also true for the adult population in general (4; 5). However, not as many studies have looked specifically at the association between physical activity and lower mortality risk in adults with type 1 diabetes. Type 1 diabetes has previously been associated with a shorter lifespan in many adults with it, particularly related to endothelial dysfunction and cardiovascular disease (6).

Earlier studies, such as the DCCT, have shown that keeping blood glucose levels in a more normal range can help lower the risk of diabetes-related complications in people with type 1 diabetes. Most deaths in this population are related to either cardiovascular events or kidney failure. Exercise has an innate ability to lower oxidative stress, which has been implicated in the development of many complications, as well as improve endothelial function (6). While regular physical activity is associated with a lower risk of early death in adults with and without type 2 diabetes, this study is one of the first to examine this association in type 1 diabetes.

While the exact amount of exercise needed to lower the risk of cardiovascular events is unknown and not determined by this study, doing any activity is arguably better than remaining sedentary. As in people without diabetes, intense activity likely is even more cardioprotective than moderate or light activity.

However, the exercise in this study was self-reported and only collected at the start of the study, making it is hard to draw definitive conclusions about how much exercise people need to do and how intense it needs to be to reduce the risk of dying.

In conclusion, as confirmed by this latest study, being physically active on a regular basis is critical to living long and well with type 1 diabetes. Remaining sedentary is far worse for your health and your longevity, so go get active!

…And Stay Active: My Profile of Success

Sheri exercising pulldown closerI would like to share some of my personal story about why physical activity matters to me and how I have lived successfully with type 1 diabetes for almost 50 years to date. My success with diabetes is undoubtedly related to my decision to be physically active.
The secret to my overall success, both professional and personal, is that I made a conscious choice to live my life by one guiding principle: Live life first, and be diabetic second. In the beginning, I’m not sure it was even a conscious choice (I was only four years old when diagnosed with type 1 diabetes), but rather just an integral part of my personality. I am not one to let obstacles keep me from reaching my goals. Having diabetes has undeniably been one of the greatest challenges to living my life the way I want to, but it has almost never been an insurmountable one.
It’s hard to even imagine life without diabetes when you get it as young as I did. I don’t remember much about being diagnosed other than feeling sluggish and tired all the time. The biggest irony was that my mother had avoided becoming a nurse because she hated needles, but the doctors wouldn’t let me out of the hospital before she learned how to give me shots. She apparently practiced for days shooting water from a syringe into an orange all week. When she gave me my first shot in my arm, she jabbed the needle so hard it rebounded back out. I am told I said, with tears streaming down my face, “Mommy, go practice on the orange some more.”
Diabetes has, in many ways, been a blessing in disguise. It likely had a positive impact on my family’s overall health because our whole family switched to the same diet that was prescribed for me at the time—a balanced diet of carbs, protein, and fat with lots of vegetables, some fruit, and very limited intake of sweets and refined foods. Having diabetes has also been a positive, shaping force in my life when it comes to exercise and physical activity. As such, I have amended my original guiding principle to include, “…and stay active” for that reason: Live life first, be diabetic second, and stay active.
While many people view exercise as a punishment, I fully embrace using diabetes as an excuse to put my workouts first! I started exercising regularly way before it was trendy and known to be good for your health (and blood glucose). I was always active as a kid, playing in the woods, building forts, and just being a tomboy. As a preteen, I began exercising regularly on my own and doing organized sports because being active was the only thing that made me to feel like I had any control over my blood glucose. Way back then no one had blood glucose meters (only inaccurate urine testing), but I could tell being active helped with my blood glucose.
To this day, I still exercise six to seven days a week, and my passion is helping others with all types of diabetes do the same—safely, effectively, and for a lifetime. I vary my daily workouts to keep them fun and to stay injury-free and advise everyone else how to do so. When people ask me how I manage to do all I do, I tell them simply, “I work out.”
Diabetes also led me to an early calling as a healthy lifestyle and diabetes motion expert. When I was about twelve, I spent a week in Kansas with my grandmother, who had what they called “borderline” type 2 diabetes. She was on yet another diet to lose weight, and I decided to help her with dieting while I was there—acting like a personal trainer or fitness coach. I weighed her in every morning, helped her measure out her food (like cottage cheese), and made her jog laps around her backyard. At the start of the week, she agreed to pay me $1 for every pound she lost with my help. She lost eight pounds that week—was I ever a rich kid! Little did I know back then that she likely lost a whole lot less after the first week and gained it all back over time. I just remember her always being about the same body size and shape every time I saw her.
Back then my grandmother was the only other person I knew with diabetes. Later when I was in graduate school working on a degree in exercise physiology, she starting suffering from myriad complications including a heart attack, followed two years later by a major stroke and smaller ones that eventually left her incapacitated. She was bedbound and unable to communicate or feed herself for most her last six years, and she had partial amputations of both of her legs due to chronic ulcers. During one visit, I looked at her and thought, I don’t want to live like that. Consequently, most of my life and career I have focused on how to stay healthy with diabetes and avoid complications. To me, what’s most important is living well while you are alive. That’s why I preach about how important a healthy lifestyle is to maintaining your quality of life (whether you have diabetes or not) and that just living a long time without good health should not be your goal.
You certainly don’t have to get a PhD in exercise physiology like I did to understand the metabolic changes that occur with exercise, but learning why it is so beneficial can be very motivating. You can virtually “erase” overeating mistakes with exercise, and you can keep yourself from getting other health conditions (like heart disease). I’m sure that I am only in excellent health after almost 50 years with type 1 diabetes because of my lifestyle choices—and I want to stay that way until I reach my last day.
As I always say, “What’s the point of living longer if you can’t live well and feel your best every day of your life?” Take my advice and live life first, be diabetic second, and stay as active as you possibly can every day of your healthy (and hopefully long) life.

Exercise Management in Type 1 Diabetes: A Consensus Statement

JDRF Consensus Statement Cover

Above you see part of the first page of a new consensus statement that comes from many of the individuals involved with the creation and launch of the new JDRF PEAK Performance Program, aimed at educating both clinicians and people with type 1 diabetes how to manage the complexities of being active. In my opinion, this recently published consensus statement on exercise and type 1 diabetes is long overdue and much needed. I managed to get the American Diabetes Association to let me chair an updated position statement (see my November blog) and include type 1 diabetes in it but, unfortunately, never just one addressing type 1 and exercise alone so this JDRF one fills a huge void.

The past decade has seen a growing number of publications related to diabetes management during exercise in people who have to either inject or pump insulin to stay alive. As you well know, whether insulin is injected or pumped, it is not being delivered where it normally ends up in a body that can release its own insulin, and this altered insulin delivery leads to alterations in hormones and blood glucose management by the liver. Normally, your liver would be able to either release or store glucose to keep your levels constant, but not without these proper hormonal signals.

Consequently, the only way you can keep your blood glucose levels normal (or near normal) with exercise is to take in carbohydrate/food, lower circulating insulin levels, or both during activities. Given that exercise is a huge stressor to normal metabolic control of blood glucose, it can make your diabetes more difficult to manage–even though exercising is generally beneficial for a number of other health reasons. This new consensus statement does an excellent job of covering all of the potential effects of engaging in differing physical activities, along with comprehensive management strategies involving changes in food intake and adjustments in basal and/or bolus insulin dosing. It also points out the many areas that need additional (or even any) research with regard to exercising with type 1 diabetes, either to enhance health or sports performance. Read it now if you haven’t already for some great advice!

Physical Activity/Exercise and Diabetes (ADA 2016 Position Statement)

ADA Position Statement CoverI would like to let everyone know about a new position statement that covers all types of diabetes (type 1, type 2, and gestational) and prediabetes and addresses physical activity and exercise. It is based on an extensive review of more than 180 papers covering the latest diabetes research and includes the expertise of leaders in the field of diabetes and exercise from top research institutions in the US, Canada, and Australia.

The most notable recommendation calls for three or more minutes of light activity, such as walking, leg extensions or overhead arm stretches, every 30 minutes during prolonged sedentary activities for improved blood sugar management, particularly for people with type 2 diabetes. Sedentary behavior—awake time that involves prolonged sitting, such as sitting at a desk on the computer, sitting in a meeting or watching TV—has a negative effect on preventing or managing health problems, including diabetes. Studies have shown improved blood sugar management when prolonged sitting is interrupted every 30 minutes—with three minutes or more of standing or light-intensity activities, such as leg lifts or extensions, overhead arm stretches, desk chair swivels, torso twists, side lunges, and walking in place. Physical movement improves blood sugar management in people who have sedentary jobs and in people who are overweight, obese and who have difficulty maintaining blood sugars in a healthy range.

These updated guidelines are intended to ensure everyone continues to physically move around throughout the day – at least every 30 minutes – to improve blood glucose management. This movement should be in addition to regular exercise, as it is highly recommended for people with diabetes to be active.

Since incorporating more daily physical activity can mean different things to different people with diabetes, these guidelines offer excellent suggestions on what to do, why to do it and how to do it safely. It includes various categories of physical activity—aerobic exercise, resistance training, flexibility and balance training, and general lifestyle activity—and the benefits of each for people with diabetes.

Aerobic activity benefits patients with type 2 diabetes by improving blood sugar management, as well as encouraging weight loss and reducing cardiovascular risks. Movement that encourages flexibility and balance are helpful for people with type 2 diabetes, especially older adults. Regular aerobic and resistance training also offer health benefits for people with type 1 diabetes, including improvements in insulin sensitivity, cardiovascular fitness and muscle strength. Women who are at-risk or diagnosed with gestational diabetes are encouraged to incorporate aerobic and resistance exercise into their lives most days of the week. People with prediabetes are urged to combine physical activity and healthy lifestyle changes to delay or prevent a type 2 diabetes diagnosis.

Recommendations and precautions for physical activity and exercise will vary based on a patient’s type of diabetes, age, overall health and the presence of diabetes-related complications. Additionally, specific guidelines are outlined on monitoring blood sugar levels during activity. The statement also suggests positive behavior-change strategies that clinicians can utilize to promote physical activity programs.

Are You an Exercise Non-Responder?

Roger Hanney (T1D)When researchers have done studies on adults with type 2 diabetes, although the participants as a whole have a positive average response to exercise training, as many as 15 to 20 percent of type 2 exercisers have been found to be “non-responders” (1). These are individuals who appear to be resistant to the beneficial effects of exercise training of all types because exercise training for them fails to improve their A1C (overall blood glucose control), body fat, body mass index, or other metabolic measures. But are there really exercise non-responders? And, if so, are you one of them?

Some researchers have blamed the exercise “non-response” observed in a minority of research subjects on inheriting bad genes. However, a large part of the data that these scientists used to “prove” their case came from animal research. For example, successive generations of rats have been bred until they had either a very high aerobic capacity or a low one, and the researchers then applied their findings that those animals with a low aerobic capacity don’t gain the same metabolic benefits directly to humans.

People are far from being similar to lab rats, though! We’re much more genetically diverse, and our muscles can improve their aerobic capacity with training, regardless of what genes we inherited from our parents (2). In fact, a recent review of 18 training studies concluded that normal training adaptations to aerobic exercise are possible in adults with type 2 diabetes (3), again suggesting the environment is a more viable explanation for those few who don’t respond like everyone else.

What are these environmental factors? For starters, a big issue with human aerobic training is that not all individuals in exercise studies end up training similarly, despite the good intentions of the researchers. I know from training hundreds of research subjects over the years that many older people don’t push themselves as hard as they could when they’re doing the initial exercise test (especially when riding a cycle that makes their legs hurt), and their training protocol is then set up based on a lower-than-actual maximal capacity. So, they may simply not be doing as much total training or expending as many calories during exercise as others in the study.

Many older adults with diabetes also have joint issues or health problems that limit their ability to exercise, including excess body fat, high blood pressure, or nerve damage in their feet. What’s more, what people eat is seldom controlled well in exercise studies, and taking in excess food can override the benefits of exercise, including limiting how long or high insulin action is elevated and blood glucose control after workouts (4). In other words, it’s entirely possible to negate the effects of the last bout of exercise and diminish its acute (and chronic) metabolic benefits by overfeeding.

Simply being less active during the rest of the day can also impact whether you experience the expected results of doing the training. Not surprisingly, people who are more active all day long and not just during training sessions fare better as far as their metabolic health is concerned, even when exercise training is the same for all participants in a study (5).

Even the medications you take can limit your responses to doing exercise training. The most commonly prescribed medication for type 2 diabetes is metformin, and taking metformin can blunt your normal metabolic response to exercise training (6). Taking statins to lower your blood cholesterol can cause some muscular problems that may limit your ability to exercise, as can some other medications commonly prescribed for other health problems.

Even if it’s not the environment that is holding you back and you do have some genetic traits that may limit your exercise response, that certainly doesn’t mean that you won’t gain a lot of other health benefits—both physical and mental—from being more physically active. There really is no evidence that the potential to response to exercise training is limited if you have type 2 diabetes, type 1 diabetes, prediabetes, or obesity; in fact, even breaking up prolonged sitting time has measurable metabolic benefits for everyone (7). So, get up and go be active doing whatever you enjoy the most—and be as active as you possibly can all day long. Your body will thank you for it!

Losing Weight by Being Active Is Best

Rose Scovel T2D (crop)Did you know that your body stores fat from excess calories in places other than fat cells? Both your muscles and your liver store extra fat as you gain excess fat weight (1). More fat storage in your muscles may decrease the removal of glucose from your blood, making muscles more resistant to insulin if you don’t exercise regularly (2; 3). Given that your muscles are responsible for the majority of blood glucose uptake in response to insulin, developing insulin-resistant muscles has a substantial impact on your blood glucose. Regular exercisers, paradoxically, can store more fat in their muscles without experiencing insulin resistance, suggesting that the total amount of fat stored there isn’t the critical component but rather how muscles respond to insulin (4).

The greater release of insulin that results from eating excessive amounts of carbohydrate may cause you to gain body fat because carbohydrates are usually converted into and stored as fat when you’re sedentary. If you store fat just in fat cells (particularly in the ones under the skin), you probably will not have as many health problems compared to putting it elsewhere. For example, storing extra fat in your liver may contribute to low-level inflammation, which can lead to the development of insulin resistance, diabetes, heart disease, and other metabolic disorders. Therefore, your liver (and whether or not it stores excess fat) may prove to be a crucial link between weight gain and the development of insulin resistance (1).

An insulin-resistant liver may lead to elevated blood fats and cholesterol levels that contribute to the development of heart disease. You can compound the problem by with dietary choices that contribute to your liver’s insulin resistance, including foods high in refined carbohydrates and highly processed ones. You can lower inflammation and improve your metabolic health with lifestyle changes, including exercising more (5). In fact, being active and eating more fiber naturally in your diet are likely the two most important changes you can make to lower your risk of all metabolic diseases (6).

You don’t have to lose a lot of weight: losing just ten pounds improves your insulin action, lowers inflammation, enhances good cholesterol and lowers the bad, improves metabolic efficiency, and reduces type 2 diabetes risk. Going on a diet to lose weight, however, is not the best long-term solution to managing your body weight or reducing your diabetes risk.

Why? Dieting does not work for most people. It becomes progressively harder to lose weight the longer you stay on a diet (thus making it harder for you to stay motivated to follow it); consequently, many people give up after a while.

A bigger problem is that you are not likely to keep off any weight that you do lose. More than nine out of ten dieters who have successfully lost weight ultimately regain the pounds they struggled to lose. If you go back to eating the same foods after your diet ends that you ate before, you will typically rebound by taking in excessive calories, particularly in the form of extra fat that quickly returns you to your former weight. In fact, most people gain back even more than they lost, regardless of the diet they followed. A greater percentage of the weight you regain is usually body fat, ultimately making your body fat higher than if you had never lost any weight.

While your body’s set point—or what you normally weigh—can change gradually over your lifetime, it remains the same over the relatively short time frame of a diet, unless you make permanent lifestyle changes. If you maintain high levels of daily physical activity while you’re losing weight, though, that will help you prevent gaining it back later on (7). So, if you have to choose between dieting and being more active to lose weight, always choose motion, even if weight loss is slower with exercise alone.
