Good advice for college students. And everyone else.

This came to my attention recently. It’s an infographic about how college students can stay active, get fit, and avoid the dreaded “Freshman 15.”

This is good advice for the rest of us, too. Replace dorm room with living room and cafeteria with kitchen and you have a simple and effective way to improve your health.

The Best Regimen for College Fitness

By the way, studies of weight gain during college show that it isn’t really the Freshman 15. Research shows it’s more like the Freshman 4.6. But that doesn’t have the same impact, does it?

My Friend Shannon is in the newspaper!

My Health & Fitness column in the Aiken Standard this week is about my friend Shannon and her remodeling project. I have been writing about Shannon on this blog for some time, but I thought her story was worth sharing elsewhere.

Shannon has been trying to do what I call remodeling–losing a little weight and adding some muscle. To do this she started an exercise program and is now exercising nearly every day. She has also changed her diet, focusing mostly on eating out less, reducing portion sizes, and eating more fruits and vegetables.

It has been working!

What is interesting about Shannon is that the specifics of her diet and exercise program aren’t the reason for her success. Yes, that is how she lost fat and added muscle, but she could have done that following almost any diet and exercise program.

What helped Shannon the most is that she changed her habits. For years she didn’t exercise much and ate a diet that consisted largely of unhealthy foods. This was mostly due to convenience–it was easier to eat out and not exercise.

Changing these behaviors was the real challenge. Shannon’s lifestyle and interactions with others supported her former habits. And changing these habits isn’t easy. It means saying “no, thank you” a lot and making difficult choices about what to eat and when to exercise.

But she has done it and learned along the way that she really can make those tough decisions. And so can everyone else. The key is to focus on WHY we eat what we eat and WHY we don’t exercise rather than obsess about exactly WHAT to eat and WHAT to do for exercise.

Weight loss reduces physical limitations and improves physical function.

Last week I presented a study at the American College of Sports Medicine Annual Meeting in Indianapolis showing that weight loss can improve physical function and reduce physical limitations. This study was also the topic of my Health & Fitness column in the Aiken Standard this week.

In this study 48 subjects followed a low-calorie diet (~1200 calories/day) and participated in daily exercise (progressing to 60 minutes per day of walking). The diet and exercise programs resulted in significant weight loss, about 13 pounds on average, or over 1.5 pounds per week.

We assessed physical function using a simple physical test called the timed get-up and go test (TGUG), in which the time required to rise from a chair, walk 10 feet, and return to the chair was measured. The subjects also completed the physical functioning domain of the Short-Form 36 Health Status Survey (SF-36), a subjective reporting of health-related quality of life.

Following weight loss the TGUG time was lower, meaning the subjects were able to complete the test more quickly. The SF-36 Physical Function score was  higher. Together, these tests indicate that the subjects were experiencing improved physical function and fewer limitations to normal activities

This is important because physical limitations can have a big impact of quality of life. Being overweight makes simple physical tasks, such as bending over and tying your shoes, challenging. Losing weight can make these things easier, improving quality of life.

This is consistent with what many people who have lost weight report: “I feel so much better now than I did when I was heavy,” or “I didn’t realize how difficult things were for me.”

Sometimes, it’s the little things that count the most!

 

What is one portion?

I think everyone knows that we have become accustomed to large portion sizes. And large portion sizes can add up to too many calories which can add up to weight gain.

Unless you have read a food label and carefully measured out one serving you may not realize how big your “normal” portions really are. This video will show you:

When you are done with that one, check out this video that shows what 2000 calories, the “typical” recommended daily intake, looks like coming from some of your favorite foods:

 

 

Using a physical activity time machine to explain the obesity epidemic.

What caused the current obesity epidemic? Is it that we are eating more now? Or are we less active than we were? Most likely, it is a combination of both. And although the typical American diet is given plenty of blame for causing people to gain weight, a low level of physical activity deserves attention, too.

One way to answer this question is to look back at what life was like about 100 years ago, when obesity was uncommon. Unfortunately, no one thought to make accurate measures of daily activity back then. But there is a way to go back in time and assess the diet and physical activity that was common 100 years ago.

In my Health & Fitness column in the Aiken Standard this week I wrote about an interesting study that essentially took researchers back in time to measure physical activity. The results show that we are much less active today, which certainly plays a big role in the obesity epidemic.

You can learn more about the study I mentioned here.

It’s not just for kids: Adults need recess, too.

The childhood obesity epidemic is usually blamed, in part, on the fact that most kids aren’t active enough at home and at school. Opportunities for activity in school are less common now because programs like physical education and recess are being cut in an effort to save money or to dedicate time for test preparation. This has an effect not only on health but on academic performance, since regular activity improves attention, memory, and learning (in addition to the health benefits).

Parents are partly to blame, too. There are plenty of missed opportunities for physical activity outside of school. Since most adults don’t get enough activity, it is no surprise that they aren’t encouraging their kids to be active.

Adults get the same benefits from regular physical activity as children do. Just as kids who are active during the  day perform better at school, adults who are active at work are more productive. But most people spend much of their work day sitting with little to no activity. This is bad for health and for job performance.

So why don’t adults get recess, too? They should!

This is the topic of my Health & Fitness column in the Aiken Standard this week. It is also the mission behind an initiative called Instant Recess, which provides tools to help people include short activity breaks into their day. Far from being a burden or a waste of time, these short bouts of activity improve health, mental wellbeing, and productivity.

Missed opportunities to promote physical activity for kids.

Most kids don’t get enough physical activity. No surprise that inactivity is associated with health conditions like obesity, high blood pressure, and diabetes. But a lack of activity in children can lead to poor academic performance, too.

But we are missing good opportunities to provide kids with chances to be physically active at home and in school. This is the topic of my Health & Fitness column in the Aiken Standard today.

Schools are a perfect place to include opportunities to be active. Unfortunately, opportunities for activity, from PE to recess, are among the first cuts to be made when budgets are tight. Why isn’t promoting an active, healthy lifestyle  just as important as promoting math or reading or science?

A common argument is that parents should teach their children about a healthy lifestyle, not schools. I disagree. At some point, we (society) decided that parents shouldn’t have to teach their kids math or reading or science. I don’t know the exact rationale, but it likely had something to do with the fact that most parents don’t have the knowledge or skills to teach these essential subjects. Why should activity and, while we are at it, nutrition, be any different?

In fact, we have been experimenting with removing  physical activity and nutrition education from schools and leaving it to parents for some time now. Given the childhood (and adult) obesity epidemic, it hasn’t gone well. Maybe it is time to revisit providing quality health, activity, and nutrition education in schools.

If you want to learn more about benefits of and ways to promote physical activity for kids the Physical Guidelines for Americans is a good place to start. In particular, the Midcourse Report offers recommendations and solutions regarding physical activity in children.

Eating healthy and saving money–it can be done! And your family should try it.

I read this interesting article in USA Today about a family who is working together to lose weight by eating healthy and exercising more. The family is participating the USA Today’s Family Fitness Challenge, which provides them with expert advice.

Predictably, their fitness is improving and they are losing weight (over 100 pounds total so far). One family member even quit smoking!

What may be surprising is that they are saving money following their new healthier diet. By preparing most meals at home they are saving about $300 per week on food!

Another happy consequence is that they are spending more time together as a family by eating meals  and exercising together. No doubt this is good support for them as they try to improve their health.

They are doing this as part of  a TV show (The Doctors) and they have an exercise physiologist and a nutritionist working with them, so it would be easy to think that a typical family without this support wouldn’t be successful. I disagree.

I think that if most families started preparing dinners at home, eating as a family, and going for a walk (or doing some other activity) together after dinner they would get in better shape, lose weight, and benefit from more time together.

Candy and soda for breakfast! The truth about popular children’s breakfast foods.

Breakfast is the most important meal of the day, right? A healthy breakfast can help kids pay attention and do better in school. In adults, a good breakfast can reduce hunger and help with weight control. That’s probably not new.

You may be surprised to learn that many  popular breakfast foods for children—and adults—are anything but healthy. In fact, many of these choices more closely resemble candy and soda than a healthy start to the day!

This is the topic of my Health & Fitness column in the Aiken Standard this week. It was also a project that one of my students, Brittney Austin, worked on this semester. While some of the results clearly showed that some breakfast foods were essentially candy, like frosted Pop-Tarts which have nearly as many calories and as much sugar as a Reese’s Peanut Butter Cup.

In other cases, the comparison is more complicated. For example, Sunny D orange drink contains only 5% juice but has as much added sugar as a Coke. It is essentially orange soda without the bubbles. But when you consider that 100% orange juice has as much sugar as the Sunny D, maybe the “orange soda without bubbles”  isn’t so bad.

But it is! While it is true that the sugar content is essentially the same, the real orange juice also contains vitamins and minerals. And  even though some “juice” drinks have added vitamins and minerals, the real juice is still better. Here’s why: children who drink the artificially sweetened juice flavored drinks may become accustomed to the unnaturally sweet taste and find that they don’t like naturally sweetened juice or whole fruit. So even if the nutrients are the same as real juice, the “juice” drinks can lead kids away from eating fruit—a bad outcome!

Take a close look at what your children eat for breakfast. Is it a healthy meal or candy and soda in disguise? And take a good look at your own breakfast. It may not be much better!

Fat but fit, Santa is ready to go!

He may not look it, but Santa probably hits the gym regularly to work on the strength, endurance, and flexibility he needs for his job. Since Santa tends to keep to himself, he hasn’t come to my lab for a fitness test. But I tried to make a good guess as to what he does in the “offseason” to stay in shape in my Health & Fitness column in the Aiken Standard.

It’s a good thing he keeps himself in shape, too. Since he is overweight, good fitness is essential for reducing his risk of, among other things, a heart attack or stroke. In fact, Santa is probably healthier than some people who have a “normal” weight, but don’t exercise.

He should watch his weight, though. An ABC News report suggests that Santa is getting fatter!
