The Dangers of Excess Body Fat

Posted on by

Most people’s primary motivation for weight management is to improve their appearance. Equally important, however, are the many other benefits of proper nutrition and regular exercise.

Weight management through reduction of excess body fat plays a vital role in maintaining good health and fighting disease. In fact, medical evidence shows that obesity poses a major threat to health and longevity. (The most common definition of obesity is more than 25 percent body fat for men and more than 32 percent for women.) An estimated one in three Americans has some excess body fat; an estimated 20 percent are obese.

Excess body fat is linked to major physical threats like heart disease, cancer, and diabetes. (Three out of four Americans die of either heart disease or cancer each year; according to the National Health and Nutrition Examination survey, approximately 80 percent of those deaths are associated with life-style factors, including inactivity.)

For example, if you’re obese, it takes more energy for you to breathe because your heart has to work harder to pump blood to the lungs and to the excess fat throughout the body. This increased work load can cause your heart to become enlarged and can result in high blood pressure and life-threatening erratic heartbeats.

Obese people also tend to have high cholesterol levels, making them more prone to arteriosclerosis, a narrowing of the arteries by deposits of plaque. This becomes life-threatening when blood vessels become so narrow or blocked that vital organs like the brain, heart or kidneys are deprived of blood. Additionally, the narrowing of the blood vessels forces the heart to pump harder, and blood pressure rises. High blood pressure itself poses several health risks, including heart attack, kidney failure, and stroke. About 25 percent of all heart and blood vessel problems are associated with obesity.

Clinical studies have found a relationship between excess body fat and the incidence of cancer. By itself, body fat is thought to be a storage place for carcinogens (cancer-causing chemicals) in both men and women. In women, excess body fat has been linked to a higher rate of breast and uterine cancer; in men, the threat comes from colon and prostate cancer.

There is also a delicate balance between blood sugar, body fat, and the hormone insulin. Excess blood sugar is stored in the liver and other vital organs; when the organs are “full,” the excess blood sugar is converted to fat. As fat cells themselves become full, they tend to take in less blood sugar. In some obese people, the pancreas produces more and more insulin, which the body can’t use, to regulate blood sugar levels, and the whole system becomes overwhelmed. This poor regulation of blood sugar and insulin results in diabetes, a disease with long-term consequences, including heart disease, kidney failure, blindness, amputation, and death. Excess body fat is also linked to gall bladder disease, gastro-intestinal disease, sexual dysfunction, osteoarthritiis, and stroke.

10 Ways to Keep Your Fitness Plan on Track During the Holidays

Posted on by

The average American does a little too much celebrating at this time of year. Between Thanksgiving and the New Year, most of us will gain seven pounds as a result of indulging in extra helpings, snacking on holiday treats, having an extra glass of wine and exercising less.

Life Time Fitness, Inc., a Healthy Way of Life company that operates 30 multi-purpose, state-of-the-art Sports, Fitness and Recreational Centers in eight national markets — Minnesota, Illinois, Michigan, Ohio, Indiana, Virginia, Arizona, and Texas — has set the industry standard in providing consumers with the absolute finest in sports and fitness centers

“This is an especially challenging time of year for those who are trying to maintain healthy habits such as working out and eating low-fat, low-calorie foods,” says Jeff Zwiefel, vice president of the nutritional products division at Life Time Fitness. “We’re constantly urged to have another helping, enjoy a holiday treat or skip the workout to go shopping instead. No wonder nearly everyone gains weight,” he points out.

But complete deprivation is not the answer. “The holidays are meant to be enjoyed,” Zwiefel says. “At Life Time Fitness, we think it’s possible to balance healthy habits with enjoying special gatherings and traditions. We encourage balance and moderation in all areas of your life,” he says.<

Here are 10 great tips, courtesy of Zwiefel, for staying fit and eating well over the holidays.

  1.  Drink lots of water throughout the day. It suppresses the appetite and is something everyone should do year round.
  2.  Snack on fruits, vegetables and high-fiber foods whenever possible. Dried fruits are healthy and a good alternative to many sweet snacks such as cookies and candy.
  3.  Limit alcohol consumption. Remember that alcohol contains almost as many calories per gram as fat. Alternate alcoholic drinks with water or club soda while you’re at a party.
  4.  Enjoy the outdoors as much as possible: bundle up and take the dog for a walk, and try skating or sledding; squeeze 10-minute walks into your schedule. Any extra activity helps.
  5.  Health and fitness centers offer a combination of cardio and resistance-training opportunities, as well as group fitness classes and personal training, that are essential to maintaining a healthy way of life. If you’re thinking about joining a fitness center, fall is a great time to sign up.
  6.  Acknowledge that you’re probably going to miss some workouts during this time and plan now to work around it. Schedule different times or substitute another activity, even if it’s at home.
  7.  Eat a nutritious meal or snack before you attend events or parties where there is a lot of food, or use a small plate to avoid overindulging. Another good tip is to leave at a reasonable hour. In addition to helping you get enough sleep during this hectic time of year, you’ll also be removing yourself from the temptation to continue eating unnecessary calories.
  8.  For the 9 out of 10 adults who do not get the essential daily vitamins and nutrients from the food they eat, nutritional supplements should be considered. Life Time Fitness offers a full line of nutritional products, including men’s and women’s multivitamins, energy bars and shakes and weight-loss supplements.
  9.  Enlist the help of a family member or friend to help keep you on track with healthy habits during the holidays. Choose someone who can provide not only encouragement, but a good example as well.
  10. Remember that balance, variety and moderation apply to holiday celebrations as well as to most other things in life, so don’t be too hard on yourself if you slip up. Keep your good intentions, spend time with family and friends and enjoy the holidays.

Beginners Guide to Getting Fit

Posted on by

The very thought of going from zero fitness and marshmallow softness to full stamina, firmness and energy can seem overwhelming – enough to make you want to lie down. But even against the odds and the tide of excuses and a history of couch-potatoness, you can start. And you can continue.…into a regular routine of exercise. If you’re at this point in your life, you’re the right candidate for transformation. This plan just may be your best bet.

Change is an all-or-nothing proposition. You either do it, or you don’t. You can’t just exercise for 3 times one week, once the next week, take a couple of weeks off, go twice a week, and so on and expect to reap all the benefits.Only a handful of people can get into a regular exercise routine by suddenly beginning to exercise. Something just clicks inside and they workout with energy, and they enjoy it. But for the other 95%, getting into a regular routine with exercise is not so easy.

For these people, beginning an exercise program comes in stages, step by step, many of which happen before you even slip on your workout shoes or enter the gym. The very fact that you’re reading this article means that you’re already in one of the important first stages. And continuing to exercise regularly is also a process of change, a cycle of smooth sailing and bumpy seas.

Fortunately, there are techniques that you can use to help you move to the next level. Just be aware that the stage you are in changes all the time. Of course, once you know where you are, it’s easy to see what’s next. Here’s how to get there….

Five common weight loss mistakes

Posted on by

Not changing your calorie plan as you lose weight. The fallacy of the “1200 calorie diet” plans and the like.

Most people fix their calorie intake to a given number and expect to lose weight at the same constant rate over a period of weeks. Hence, dieters look for 1000 calorie or 1800 calorie diet plans on the internet. The fixed calorie diet plans don’t work. If you burn 3000 calories a day at the start of a diet, after a week or two of losing some weight, you are no longer burning 3000 calories. Now you might be burning 2800 calories. If you fix your calorie intake in the face of a decreasing calorie expenditure, your weight loss will slow down more and more as you lose weight.

If you want to lose weight at a constant rate, you must repeatedly:

* decrease your calorie intake to accommodate the calorie expenditure drop
* increase your calorie output by exercising more
* do both

I would like to note that you must set realistic slow weight loss goals. If you go for fast weight loss you would not be able to sustain it for a long period unless you go extreme in the calorie reduction and exercise a lot. For people who have to lose more than 20 pounds (10kgs), the goal should be a loss of no more than 2 pounds or 1 kg per week. People who need to lose just a bit of weight should go for weight loss of 1 pound or half a kilogram per week.

Why does my calorie expenditure drop as I lose weight? The most important factors are:

* You weigh less. A smaller body burns less calories both at rest and while active
* You may involuntarily burn fewer calories. Dieters often lack energy and move less
* Calorie restriction suppresses the metabolic rate
* You have less body fat, which may further suppress your metabolic rate

These major factors contribute to an ever-decreasing energy expenditure as one loses weight. The more a dieter cuts calories, the bigger the calorie expenditure drop. The leaner the dieter, the greater the calorie expenditure drop.

Now you must understand that if you want to succeed in losing weight, you have to make changes in your nutrition plan. I recommend burning more calories, because being more active facilitates smaller calorie restriction and milder calorie expenditure drop.

It is very difficult to estimate the rate of the metabolic drop. Here is the general rule: the bigger you are, the smaller the rate of the metabolic drop. The more weight you lose, the more you have to cut calories or increase exercise. If you are overweight you might need to cut just 10 more calories for every lost pound, while if you are lean you might have to cut 60 calories for every pound lost. I picked these numbers just as an example.

Cardiovascular Exercise Principles and Guidelines: Part One

Posted on by

For maximum effectiveness and safety, cardiovascular exercise has specific instructions on the frequency, duration, and intensity. These are the three important components of cardiovascular exercise that you really need to understand and implement in your program. In addition, your cardiovascular program should include a warm-up, a cool-down, and stretching of the primary muscles used in the exercise. This article is part one of a two part series discussing the very important principles and guidelines of a safe and effective cardiovascular exercise program. Part one will explain the proper methods of warming-up, stretching, and cooling-down and discuss the frequency and duration of a sound cardiovascular routine. Part two will discuss how to monitor exercise intensity and heart zone training.

Warming Up and Stretching
One very common mistake is stretching before muscles are warmed-up. It is important to stretch after your muscles are warm (after blood has circulated through them). Never stretch a cold muscle. First warm up. A warm-up should be done for at least 5-10 minutes at a low intensity. Usually, the warm-up is done by doing the same activity as the cardiovascular workout but at an intensity of 50-60% of maximum heart rate (max HR). After you’ve warmed-up for 5-10 minutes at a relatively low intensity, your muscles should be warm. To prevent injury and to improve your performance, you should stretch the primary muscles used in the warm up before proceeding to the cardiovascular exercise.

Cooling Down

The cool down is similar to the warm-up in that it should last 5-10 minutes and be done at a low intensity (50-60% of max HR). After you have completed your cardiovascular exercise and cooled-down properly, it is now important that you stretch the primary muscles being used. Warming-up, stretching, and cooling-down are very important to every exercise session. They not only help your performance levels and produce better results, they also drastically decrease your risk of injury.

Frequency of Exercise
The first component of cardiovascular exercise is frequency of the exercise, which refers to the number of exercise sessions per week. To improve both cardiovascular fitness and to decrease body fat or maintain body fat at optimum levels, you should exercise (cardiovascularly) at least three days a week. The American College of Sports Medicine recommends three to five days a week for most cardiovascular programs. Those of you who are very out of shape and/or who are overweight and doing weight-bearing cardiovascular exercise such as an aerobics class or jogging, might want to have at least 36 to 48 hours of rest between workouts to prevent an injury and to promote adequate bone and joint stress recovery.

Duration of Exercise
The second component of cardiovascular exercise is the duration, which refers to the time you’ve spent exercising. The cardiovascular session, not including the warm-up and cool-down, should vary from 20-60 minutes to gain significant cardiorespiratory and fat burning-benefits. Each time you do your cardiovascular exercise, try to do at least 20 minutes or more. Of course, the longer you go, the more calories and fat you’ll “burn” and the better you’ll condition your cardiovascular system. All beginners, especially those who are out of shape, should take a very conservative approach and train at relatively low intensities (50-70% max HR) for 10-25 minutes. As you get in better shape, you can gradually increase the duration of time you exercise.

It is important that you gradually increase the duration before you increase the intensity. That is, when beginning a walking program for example, be more concerned with increasing the number of minutes of the exercise session before you increase the intensity, by increasing your speed or by walking hilly terrain.

Please check back for Part Two, where I’ll discuss how to monitor your training intensity and how to use heart zone training to achieve the specific results you desire. Until then, remember that cardiovascular exercise should be done a minimum of three times a week and a minimum of 20 minutes per session. Once your muscles are warm (after warm up) and after the cardiovascular exercise, you should stretch those muscles used in the exercise. For example, after bicycling, stretch your quadriceps, hamstrings, calves, hips, and low back. After doing the rowing machine, stretch your legs, back, biceps, and shoulders. Good luck and enjoy all the wonderful benefits of cardiovascular exercise.

Setting and Achieving Milestone Fitness Goals Promotes Healthy Living

Posted on by

Too many people sign up for exercise programs only to quit after a
few sessions. The most popular excuses include, “I don’t have time,” “I’m
too tired,” and “It’s not working for me.”

“Rather than just saying you’ll go to the gym a few days a week and then
breaking that promise, we encourage people to set specific goals for themselves
and build a defined exercise and diet program to achieve them,” says Kendall
Harrell, personal training manager for Life Time Fitness, a national health,
fitness and nutrition company.

Harrell says setting a specific goal allows the individual to focus on
training and drives motivation to exercise. “It’s a lot easier to make it to
the finish line if you have the goal in sight,” adds Harrell.

For this reason, Life Time Fitness produces a series of athletic events,
which serve as milestone challenges for members and non-members alike, who are
seeking to set and achieve their fitness goals. At any point in time, thousands
of amateur athletes from across the country and around the world are in training
for these events.

Perhaps the most significant upcoming event is the 2004 Life Time Fitness
Triathlon. scheduled to take place Saturday, July 17, 2004, in Minneapolis, Minn.
The world-class event will feature same day network television coverage, the
sport’s largest prize purse, and an exciting field of the best professional
triathletes from around the world. What’s more, some 2,300 amateur athletes
participate in the event, competing against each other on the same course as the
professionals.

Why? Harrell says it’s all about establishing a destination event that
supports your health and fitness goals. “Deciding to compete in an event like
the triathlon really challenges you to get in shape. The first step is to
register. Once you commit to the event, you know the date and, importantly, the
amount of time you have to train until your competition. This can be a key
motivator in terms of establishing and sticking to your defined fitness regimen,”
says Harrell.

Life Time Fitness Triathlon Training Courses, tailored for beginners and
advanced triathletes alike, are offered in the months and weeks leading up to
the race. The weekly courses educate people on training schedules, strength and
pace training, and the use of training equipment. Athletes also receive
instruction in swim, bike, run and transition skills, and benefit from the
opportunity to consult with a triathlon coach.

But, if a triathlon seems a bit too daunting, plenty of other similar goals
are well within your reach. For example, consider running in your first five or
ten kilometer race. Life Time Fitness offers 5k Reindeer Run events in several
markets nationwide. The company also sponsors the Life Time Fitness Desert Dash,
an annual adventure race in Nevada, for those seeking even more thrilling
fitness challenges.

What’s important is less about the specific event, but rather, taking
advantage of an event to help you maintain your health, fitness and nutrition
program. So, take the initiative to find an athletic event that sounds fun and
challenging. Then, set your fitness goals and come up with a plan for achieving
them. It’s never too late to pursue a healthy way of life!
