Scientific Evidence: Aerobic Exercise Suppresses Appetite

Following is an excerpt from an article I read on ScienceDaily.com that backs up my claim of aerobic exercise suppressing appetite.
"A research team evaluated blood levels of BDNF (brain-derived neurotrophic factor) before and after a three-month program of aerobic exercise in 15 overweight men and women. The seven men and eight women, ages 26 to 51, worked out on a treadmill and bicycle. They were asked about their calorie intake and told to continue eating their usual number of calories. The participants were unaware that one of the study's objectives was to evaluate changes in food intake.

At the end of the study, the subjects had decreased BMI, waist circumference, and blood pressure, the data showed. They also reported consuming fewer calories than at the beginning of the study. Over the three months, BDNF levels greatly increased. The higher the concentration of BDNF, the less the subject's intake of calories and the greater the weight loss.

Thus, it is possible that increases in BDNF suppress appetite, she said. They did not test appetite suppression directly, but some past studies have shown that aerobic exercise suppresses appetite."

Working It Out - One Day at a Time

I don't like exercise.

Well, let me rephrase that. I like exercise once I get started but the thought of exercising does not get me pumped, if you know what I mean.

But as the saying goes, "Plan the work then work the plan." In other words, if you don't set out to do something, you'll never get it done. Especially when it comes to doing something you don't feel like doing.

I have to make myself exercise. The way I do that is I schedule exercise into my day. I know as soon as I get home, while I have an empty stomach, I'm going to exercise. No ifs, ands, or buts about it.

The week wasn't without it's challenges of course. I noticed my back was a little bit sore last week. I wasn't sure if I hurt my back while exercising or if I slept wrong. But with each passing day it got progressively worse, to the point that on Sunday it hurt to move. Last Thursday, I started taking AIM Frame Essentials® because it has always helped me with occasional back and knee problems I've had in the past. It's done me a world of good because I can tell this evening my back is almost back to normal. Having a strong, healthy back is crucial to my exercise goals. With it being so sore I had to temper my workout somewhat so it is very exciting for my back to feel good again.

I don't have any weight loss to report this week because I am gaining muscle. I weighed myself Sunday morning and found I had gained a pound. I felt lighter and thought the scales would reflect that. I didn't let the weight gain get to me because I know I'm building a foundation. My clothes are looser and my tummy is flatter.

I've decided to weigh and take my measurements on a monthly basis. The six week program, Slim In 6, that my daughter and I are doing right now will end on July 14th. I will give a progress report at that time. Like I said, I don't like exercise. But I'm loving the results!

What Everybody Ought To Know About Exercise

Two Ladies ExercisingI have been exercising daily for the past nine days, doing the Slim in 6 'Ramp it Up' workout.

I had forgotten how good exercise makes me feel - physically, emotionally, and mentally. I feel like a new person. I feel healthy and clean on the inside.

In addition to my appetite decreasing, my cravings for unhealthy foods has decreased as well. Instead, I've been wanting to drink more water.

The only explanation for how I feel now is the fact that I've been exercising.

Here's a quote from the article below:
"Volkow knows - from her own 6-mile daily runs and from her scientific experiments - that the brain literally likes physical activity. Exercise seems to invigorate neurochemicals that sense and reinforce pleasure."
The article below is about the benefits of exercise as it relates to the prevention of drug or alcohol addiction. I believe that exercise can prevent food addiction as well.

Can Exercise Help Prevent Addiction To Drugs Or Alcohol?
by Lauran Neergaard, AP Medical Writer

Sure, exercise is good for your waistline, your heart, your bones - but might it also help prevent addiction to drugs or alcohol?

There are some tantalizing clues that physical activity might spur changes in the brain to do just that. Now the government is beginning a push for hard research to prove it.

This is not about getting average people to achieve the so-called runner's high, a feat of pretty intense athletics.

Instead, the question is just how regular physical activity of varying intensity - dancing, bicycling, swimming, tae kwan do - might affect mood, academic performance, even the very reward systems in the brain that can get hijacked by substance abuse.

What first caught the attention of National Institute on Drug Abuse chief Dr. Nora Volkow: A study found tweens and teens who reported exercising daily were half as likely to smoke as their sedentary counterparts, and 40 percent less likely to experiment with marijuana.

Volkow knows - from her own 6-mile daily runs and from her scientific experiments - that the brain literally likes physical activity. Exercise seems to invigorate neurochemicals that sense and reinforce pleasure.

"In children, it's innate," she notes. "Children want to move."

But the nation's children are becoming more sedentary, as illustrated by the obesity epidemic, "screen time" replacing outdoor play and a drop in school P.E. And as youngsters approach adolescence, the run around the yard that used to be fun too often becomes a chore _ the dreaded jog around the school track or the nagging to get off the couch. The sedentary teen turns into the sedentary adult.

"Why do we lose the ability to experience pleasure from physical activity?" asks Volkow.

Last week she brought more than 100 specialists in exercise and neurobiology to a two-day conference to explore physical activity's potential in fighting substance abuse, and announced $4 million in new research grants to help.

Drug treatment programs often include exercise, partly to keep people distracted from their cravings, but there's been little formal research on the effects.

The best evidence: Brown University took smokers to the gym three times a week and found adding the exercise to a smoking-cessation program doubled women's chances of successfully kicking the habit. The quitters who worked out got an extra benefit: They gained half as much weight as women who managed to quit without exercising, says lead researcher Dr. Bess Marcus.

She now is working with the YMCA on a larger, NIDA-funded study to prove the benefit.

Marcus cautions that people trying to kick an addiction have a powerful incentive to exercise. Could that possibly translate into prevention? Among the clues:

  • Rats were less likely to ingest amphetamines if their cages had running wheels, suggesting exercise stimulated a reward pathway in the brain to leave them less vulnerable to the drug's rush.

  • In people, exercise acts as a mild antidepressant and relieves stress. Depression, anxiety and stress increase risk of alcoholism, smoking or drug abuse.

  • Volkow is intrigued that attention deficit disorder and obesity both involve problems with the brain chemical dopamine, one system that drugs hijack to create addiction.

It's My Birthday and I'll Cry If I Want To

Laura EilersI'm just kidding. I don't really feel like crying. That song just popped in my head as I was posting my picture.

I turned 44 yesterday on Memorial Day. I feel a tad-bit depressed because I had hoped to be close to my goal weight by now and well, I'm not even close.

I gained a pound. I'm not at all surprised since I partied just a little too hard this week... on food that is.

The birthday festivities started early last week. On Tuesday, the girls at work took me to Fuji's Japanese Steakhouse for lunch. Then, on Saturday, the kids took me back to Fuji's for lunch and then we came home and ate Heath candy bar chocolate cake. To wrap my birthday week up, my Mom took me and the kids to New China for lunch yesterday. I tried not to overdo it, but I didn't try to be good either.

On a positive note: I woke up at 5 o'clock this morning and met my daughter, Rachael, at Acxiom's wellness center to work out. We spent 20 minutes on the dreadmill - I mean - treadmill.

I started out at 3.5 mph and as each minute passed, I bumped up the speed a notch. 3.9 mph was as fast as I went, then I would come back down to 3.6 mph and then go back up. It's called High Intensity Interval Training (HIIT). Read more about it here.

Following is my aerobic workout:

Min 1 - Walk at a level 5 out of 10. That might be a walk or a strong run depending on your fitness level
Min 2 - Walk at a level 5
Min 3 - Increase the speed to a level 6
Min 4 - Increase the speed to a level 7
Min 5 - Increase the speed to a level 8
Min 6 - Increase the speed to a level 9
Min 7 - Decrease the speed back to a level 6
Min 8 - Increase to a level 7
Min 9 - Increase to a level 8
Min 10 - Increase to a level 9
Min 11 - Decrease back to a level 6
Min 12 - Increase to a level 7
Min 13 - Increase to a level 8
Min 14 - Increase to a level 9
Min 15 - Decrease down to a level 6
Min 16 - Increase to a level 7
Min 17 - Increase to a level 8
Min 18 - Increase to a level 9
Min 19 - Increase to a level 10
Min 20 - Decrease back to a level 5

Click here to see what I had laminated and take with me to the treadmill so that I stay on track. I did this HIIT workout when I did Body-for-LIFE's 12-week challenge seven years ago and got great results.

My plan is to do HIIT on Tuesdays, Thursdays, and Saturdays and then weight training on Mondays, Wednesdays, and Fridays. Click here to see my fitness calendar.

5:00 a.m. comes early so I'd better get some sleep. I'll keep you posted on my progress!
Laura

Can You Really Be Fit but Fat? Study says No.

picture of overweight woman exercisingStudy Gives The Skinny On "Fit And Fat"
Shows Exercise Helps, But Doesn't Eliminate An Overweight Woman's Heart Disease Risk

(WebMD) Regular exercise has long been touted as the key to a healthy heart, but a new study shows it is unlikely to fully reverse a woman's chances of heart disease if she is carrying extra weight.

Researchers report in the April 28 issue of Archives of Internal Medicine that although physical activity definitely helps improve cardiovascular health, such exercise does not "eliminate the negative effects of being overweight."

The findings underscore the importance of being fit and trim and cast doubt on the newer notion that it's possible to be "fit and fat." Both obesity and a sedentary lifestyle are modifiable risk factors for coronary heart disease. Heart disease is the leading cause of death in women in the United States.

Which exerts more influence in one's risk of heart disease: exercise or weight? There's no clear-cut answer. Fat cells release chemicals that can speed up the hardening of arteries, trigger inflammation, and lead to blood clots. Exercise counteracts these potentially heart-damaging processes by improving blood vessel function.

The new study, conducted by Amy R. Weinstein, M.D., MPH, of Beth Israel Deaconess Medical Center in Boston, and colleagues helps establish the combined effect of the two risk factors. The study involved 38,987 women from the Women's Health Study. Each woman provided information about her height, weight, exercise routine, medical history, and other health habits at the beginning of the study. About half of the women were considered to be of normal weight. A little less than one-third of the women were overweight, and 18 percent were obese. According to the Surgeon General's guidelines, 34 percent were considered physically active.

During about 11 years of follow-up, 948 women developed heart disease. According to the researchers, body mass index (BMI) and exercise both individually contributed to its development. A BMI between 25 and 29 is considered overweight. A BMI of 30 or above is considered obese.

The study shows that:
  • Active women of normal weight had the lowest heart disease risk.

  • Heart disease risk was slightly higher for women of normal weight who were inactive.

  • Active women who were overweight or obese were more likely to experience
    heart disease during follow-up than active normal-weight women, but less likely than their inactive counterparts.

  • The highest heart disease risk was seen among the most inactive, heaviest
    women.
While the study shows that regular physical activity can reduce one's risk of heart disease, it suggests that weight matters, too.

"Even high quantities of physical activity are unlikely to fully reverse the risk of coronary heart disease in overweight and obese women without concurrent weight loss ," the authors conclude in the journal article. "Regardless of body weight, these data highlight the importance of counseling all women to participate in increasing amounts of regular physical activity and maintaining a healthy weight to reduce the risk of coronary heart disease."

I've lost another 2 pounds!

That makes a total of 12 pounds in four weeks. I'm very excited!

I have been exercising the past three days as well. On Saturday and Sunday, the whole family went to the high school to walk/jog the track and also run the bleachers.

Saturday: I walked/jogged 2 miles and ran bleachers four times. Total: 1 hour.

Sunday: My right heel was hurting. So rather than jog, I did a fast-walk of 1.5 miles and walked the bleachers five times. Total: 1 hour.

Today: I fast-walked around the neighborhood. Total: 30 minutes. Today was my free day (meaning I can eat whatever I want) and I enjoyed myself. :)

I had a doctor's appointment today to have my thyroid checked. Curious, I looked at my chart to see if I had lost any weight since the last time I had been there and found that I actually weigh 2 pounds more than I did last October. That let the air out of my balloon because I was expecting to see something positive.

When I go back in three months to have my thyroid checked, I'll be excited to get on the scales. The doctor will have to wipe the smile from my face. :)

Study: Video game slows weight gain, boosts confidence

Associated Press Writer - March 16, 2008

Picture of Ryan Walker
Ryan Walker, 12, is shown playing "Dance Dance Revolution Extreme" in December in Martinsburg, W.Va. Walker started playing the game in 2005 and averaged 1 to 1-1/2 hours every day on the game which has helped him shed approximately 20 pounds. AP PHOTO.
MORGANTOWN, W.Va. - After weeks of bopping along to the video game Dance Dance Revolution, Ryan Walker is trimmer and stronger and for the first time the 12-year-old feels comfortable in his own skin.

"Before, he didn't want to play with kids, go to school dances or any of those functions and now he wants to do things," says his mother, Tammy Walker.

Ryan's transformation occurred over the 24 weeks he participated in a West Virginia University study that hoped to determine if the exergame could be used to combat the nation's child obesity problem.

The study, funded in part by West Virginia's health insurance program for public employees, took 35 overweight children between the ages of 7 and 12 and asked them to gradually increase the amount of time they played the game. Each child was medically considered overweight according to his body-mass index, a measurement of body fat through a height and weight ratio.

What researchers found was that participants who regularly played and continued to eat fatty foods were able to slow down but not stop their weight gain. Researchers are calling it a "stall in weight gain."

Children who relied on the game as their sole source of exercise gained 2 pounds during the study. Those who did not play the game gained an average of 5.3 pounds.

"We didn't even attempt to change their diet, which is another reason that we didn't see significant weight loss," said WVU researcher Emily Murphy.

Instead researchers found that in addition to better artery expansion, some participants developed physical self-esteem.

The game's addictive nature, and capacity to lead to greater physical activity, earns it a comparison to drugs, with WVU researcher Linda Carson dubbing it a "gateway physical activity."

"The first night I did it about 30 times in a row, I didn't want to stop," Ryan said.

The game is played on a dance pad with eight arrows pointing forward, backward, left, right and diagonally. Players press the panels with their feet in response to arrows displayed on the video screen that are synchronized to the beat of a chosen song.

Success is measured by the player's ability to time and position his or her steps.

The study directed participants to work their way up to playing 25 songs equal to about an hour of playtime a day and researchers called weekly to check on progress.

But simply introducing exercise into lifestyles that include french fries as dietary staples won't correct obesity, researchers said. That's unfortunate news for West Virginia, where nearly 21 percent of state residents under 18 are considered overweight, according to Trust for America's Health.

The state's rural nature, which hampers the development of exercise-oriented infrastructure, is partly blamed for the problems with obesity, state nutrition officials say. Poverty also plays a role as it affects nearly 1 in 4 West Virginia children.

Even staying after school to participate in athletics or extracurricular activities is a challenge because for many students a bus ride is the only way to and from school. Because of declining populations, many boards of education have consolidated schools, forcing students to catch long bus rides back home to isolated rural homes.

"In many of our rural areas there just isn't a way to make a safe route for children to walk to school along roads that coal trucks and other fast traffic travel on," said Melanie Purkey, executive director of the state's Office of Healthy Schools.

Those are some of the reasons why the state has integrated Dance Dance Revolution into West Virginia's 160 middle schools and is encouraging school administrators to make the game available to students during free periods before and after school, Purkey said.



My daughter, Rachael and I, are going to buy this video game. It looks like a fun way toRachel Bailey before and after pics exercise and lose weight.

I Started Exercising Today!

Yup, sure did. I'm feeling it too. So when I wake up in the morning, well, let's just say it could be interesting.

Last weekend, my daughter and son went down to the local track and ran the bleachers. I felt like I should have gone with them, but I was busy on the computer. My baby was awake too, so it just wasn't a convenient time. (Sound familiar? Excuses, excuses.) I really felt guilty about it. I decided I would go with them the next time, no matter what. Well, that day came today.

It turned out to be a family affair. Paul pushed Brady in the stroller while Rachael, Dylan and I ran on the track. Well, I didn't really run. It was more like a walk/jog. A slog. Truthfully, it was more like a shuffle. Paul said to Brady, "Look at the funny Mommy!" I'm just proud I finally got movin'.

In high school, I was on the track team. I loved to run. (Can you believe that?) I wanted to run the shorter sprint events, but I wasn't fast enough. So the coach put me on the cross-country team. I quit track after that year. Long-distance running just wasn't my thing.

Today, after a warm up lap around the track, we headed to the bleachers. Paul had a good laugh watching me. I ran up and down the bleachers four times! Rachael managed seven times, while Dylan did it fourteen times. I just can't believe I'm so out of shape!

With it being Daylight Saving Time, I have decided to go to the track every day after work. "A journey of a thousand miles begins with a single step". And a few bleachers too.
