It’s hot! So get fit and stay cool in the pool.

It’s hot! Whether you are swimming laps or splashing in a lake, swimming is a great way to stay cool. Swimming is also an excellent exercise for improving your fitness and helping with weight loss. Even now with physical distancing restrictions due to the COVID-19 pandemic, swimming can be a safe way to stay cool and fit this summer.

This is the topic of my Health & Fitness column in the Aiken Standard this week.

Calories count, but don’t count calories!

When it comes to losing weight, calories count. This matters because losing weight almost always means cutting the calories that you eat and increasing the calories that you burn. This concept of “eat less, move more” is the foundation of nearly every effective weight loss program. Despite what you may have heard, losing (or gaining) weight absolutely requires altering the calories you take in or the energy you expend over time. Thanks to a host of wearable devices and mobile apps, counting calories has never been easier.

This is the topic of my Health & Fitness column in the Aiken Standard this week.

Modern wearable devices and mobile apps allow you to track your weight, what you eat, and your activity fairly accurately. Many apps can measure the intensity of exercise by using the GPS and accelerometer features of your phone itself or by syncing with a wearable bracelet or belt clip. Some include heart rate to make the estimates even more precise. Using this technology, you can count steps, measure how many miles you walk or run, and estimate how many calories you burn.

Other apps can help you track what you eat. Whether you are counting calories or concerned about the amount of protein you are eating, diet analysis apps can show you what you are really eating. Most require you to enter the foods you eat and the app calculates calories, nutrients, sugar, salt, and water intake based on standard databases. In order to get accurate results, it is important to estimate portion sizes accurately, something that is challenging even for experts. That said, these apps can be useful for tracking what you eat to help you learn about your eating patterns to develop healthier habits or meet specific goals, such as eliminating added sugar from your diet.

Activity trackers and exercise apps are especially popular for improving fitness and promoting weight loss. Both the physical activity that you do throughout the day and dedicated exercise are important for good health, physical fitness, and weight control. This technology can help you know what to do, when to do it, and how much you did at the end of the day.

Even if you aren’t concerned about exactly how many calories your burned in an exercise class or how many steps you took during the day, these devices can help you develop healthier habits. Many people are simply unaware of how sedentary they are during the day or are unrealistic about how intense their workouts really are. For many people, an accurate report of how many steps they took or how many calories they burned is helpful for gauging their success and identifying things they can improve.

While these tools can be helpful, it is important to emphasize the importance of developing healthy habits in order to improve fitness, lose weight, or keep it off. A focus on “micromanaging” steps or calories may cause you to lose sight of the “big picture” changes you want to make. For example, you should strive to be as active as you can throughout the day, even if you have already met your step or calorie goal.

Keep in mind that there are very few people who failed to meet their fitness or weight loss goal because they didn’t have the latest activity tracker or fitness app. Real success comes from making lifestyle changes to incorporate healthy eating and activity habits that you can maintain without constant reminders. While technology can help you make those changes, it does not replace the dedication needed to develop lasting eating and activity habits to promote good health.

Your metabolism explained. And the only real way to “boost” it!

 

Many people are interested in speeding up their metabolism in an effort to lose weight. There are drugs, supplements, and even certain foods that are thought to increase metabolism. The effectiveness of many of these things is unproven and some may actually be dangerous. The goal of this article, and my Health & Fitness column in the Aiken Standard this week, is to explain what the term “metabolism” really means and how it can be changed.

Diet pills


Metabolism refers all of your body’s processes that expend energy, or burn calories. Practically, this is how much carbohydrate, fat, and protein is burned throughout the day to provide energy for your cells. This matters because if expending more energy than you consume in your diet can lead to weight loss over time.

The amount of energy you expend in a day is composed of three main components: your resting metabolic rate (RMR), something called the thermic effect of food (TEF), and the energy you expend in activity.

Resting metabolic rate (RMR) is sometimes called the basal metabolic rate (BMR), but many people refer to it as their “metabolism.” No matter which name is used, it refers to the calories you burn at rest. It represents the energy needed to maintain your essential body functions: heart rate, breathing, body temperature, and normal cellular processes.

The RMR is important because it represents about 60–70% of the total calories a typical person burns in a typical day. Even though RMR is important, you shouldn’t worry about it too much.

First, it is difficult to change. RMR is based mostly on your lean body mass, so the only way to increase it is to gain muscle mass. While this is a good goal, it is challenging to do, especially while you trying to losing weight.

Second, although it does vary among people, it isn’t as different as people like to think. It is easy to think that someone who gains weight has a “slow metabolism” or that someone who is thin must have a “fast metabolism.” In reality, the RMR probably isn’t much different, certainly when you take lean body mass (muscle) into account. The explanation for the differences in weight among people probably has more to do with what they eat and how active they are.

The thermic effect of food (TEF) represents the energy needed to digest, absorb, and store the nutrients you eat. It accounts for only about 10% of your total energy expenditure and it is practically impossible to change, so you can ignore it.

Activity is the most variable component of energy expenditure and the one you can most readily change. Obviously, it will depend on how active you are, but for most people it accounts for 20–30% of total energy expenditure.

Activity includes both purposeful movement such as exercise and doing work or tasks that require you to move. Activity also includes non-exercise activity thermogenesis or NEAT, the calories you burn when you move around, but not in a purposeful way. Maintaining your posture when sitting or standing, fidgeting in your chair, or other light movements count as NEAT.

The surest way for you to increase your metabolism is to limit the time you spend sitting, be active as possible at all times, and dedicate time to exercise every day. Doing prolonged aerobic exercise such as walking, jogging, or exercise classes directly burns calories and including strength training will help increase your muscle mass, which can increase up your RMR.

The bottom line is that speeding up your metabolism requires you to move. So, get up off the couch and go for a walk!

Keep your cool while enjoying outdoor activities this summer.

It’s that time of year again: school is out and the temperature and humidity are up. Since summer is officially underway it is a good time to revisit some common sense guidelines to make exercise, work, and play outdoors in the summer heat safe and enjoyable for your entire family. This is the topic of my Health & Fitness column in the Aiken Standard this week.

  1. Drink plenty of fluids

When it’s hot you have to sweat to lose heat and maintain your body temperature. High humidity makes sweating less effective, so you sweat even more. Losing lots of water through sweating can lead to dehydration. At the very least, you probably will feel fatigued but in more severe cases dizziness, low blood pressure, and fainting can occur.

For this reason, it is important to drink plenty of fluids before, during and after your outdoor activity. As a general rule, a cup (8 oz.) of water every 15 minutes is sufficient for most people. Thirst is a good indicator of fluid needs, but you should take frequent breaks to rehydrate.

Make sure to remind kids to take breaks since they can get so busy playing that they forget. Water, juice, sports drinks, and other soft drinks are equally effective, so pick something you and your kids will drink.

 

  1. Take breaks

The longer you are active the hotter you will get and you may feel more fatigued because of the heat. Taking frequent breaks will give you a chance to rest, cool down, and get something to drink.

 

  1. Seek out shade

Being in the sun means that you will feel even hotter because you gain heat from the sun’s rays. Spending as much time as you can in the shade will help you stay cool. While this isn’t always practical for all activities, look for shady spots to take breaks.

Keep in mind that shady areas at will change throughout the day, so plan your trip to the park accordingly. Also be aware that direct sunlight can make outdoor surfaces, like playground equipment, very hot. This is another reason to find shady areas to play.

 

  1. Pick cool clothes

Lighter colored clothing will reduce heat gain from the sun. Synthetic fabrics that wick sweat from the skin can help keep you feel cooler, too. Some clothing is more resistant to UV rays than others, so look for a higher ultraviolet protection factor (UPF). Obviously, you need to find a balance between protecting your skin and allowing sweat and heat loss to keep you cool.

 

  1. Wear sunscreen

Sun exposure is the leading cause of skin cancer, and outdoor activity can increase the risk. Always use a broad-spectrum (both UVA and UVB rays) sunscreen with an SPF of 30 or higher and apply—and reapply—it according to the instructions. You should also protect your eyes by wearing a hat or sunglasses.

 

  1. Avoid the hottest times of the day

Try to plan your outdoor activity in the morning or evening to avoid the hottest times of the day. Keep in mind that the highest temperatures often occur in the late afternoon or early evening, so right after work may not be the best time for outdoor activities. Early in the morning is probably the best time since it tends to be cooler and less humid.

 

You may not be able to plan all of your activities in the shade or when it is cooler. This is especially true for people who work outdoors. In these cases, drinking plenty of fluids and taking frequent breaks is particularly important. By taking the right precautions, though, you can still enjoy your favorite outdoor activities all summer long.

FITT-SPF: How to exercise safely in the sun this summer.

People who exercise are probably familiar with FITT—frequency, intensity, time, and type—the basic principle behind almost all fitness programs. The FITT principle applies to everything from running to weightlifting to yoga. For people who exercise outdoors there are three more letters that are important to know, especially in the summer: SPF. This is the topic of my Health & Fitness column in the Aiken Standard this week.

Outdoor exercise during allergy season

Now that we are all spending much of our time at home, more and more people are seeking ways to exercise outdoors. Obviously, rules about social distancing apply, so avoid exercising in groups and keep your distance from people you meet along the way. Walking, running, and cycling are great ways to be active and are appropriate to do alone, with your immediate family, or your dog. But this also means dealing with seasonal allergies, which can make being active outdoors unpleasant for allergy sufferers.

Working (out) from home.

Right now, you are probably focused on staying healthy by washing your hands and keeping your distance from other people, especially if they are sick. But there is more you can and should do, including being active every day. Regular exercise, along with good nutrition and getting enough sleep, can strengthen your immune system, reduce stress, and help you stay fit. 

Now that most people are spending more time at home and almost all gyms and other fitness facilities are closed, your exercise routine has likely been disrupted. The good news is, you can still get a good workout at home.

Yes, you can still go to the gym! Here’s how to do it safely.

The spread of coronavirus and COVID-19 is a very real and urgent health concern right now. But focusing on hand washing and social distancing doesn’t mean you should neglect other aspects of your health, including exercise.

Yes, you can still go to the gym! Here’s how to do it and reduce your risk of spreading coronavirus (and other viruses and bacteria, too).

  1. Wash your hands with soap and water before and after your workout. If that’s not an option, using an alcohol-based hand sanitizer (at least 60% alcohol) is okay, too.

  2. Use the provided disinfectant spray to wipe down equipment, including weights, before and after you use it. Many people are good about wiping sweat from benches, seats, and other equipment but skip cleaning barbells, dumbbells, and other hand-held gear. Make sure you spray and wipe thoroughly.

  3. As much as you can, keep your distance from other people. This may mean skipping group exercise classes for now. You can always find alternatives—a session on a bike on the fitness floor instead of a spin class, for example.

  4. If your gym closes or if you decide not to go, you can still get a good workout at home. If you need ideas, try one of the many mobile apps that will guide you through a workouts, some using nothing more than your body weight.
  5. This would be a great time to go for a walk, run, or bike ride outdoors. Even if you go with a friend, the risk of virus spread is lower outdoors, especially if you keep a few feet between you. Plus there are physical and psychological benefits to outdoor exercise beyond the activity itself.
  6. If you are sick, please stay home! You can still do light activity with mild symptoms, but it’s best to take the day off if you have a cough or fever.
