The Dangers of Excess Body Fat

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

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.

As long as you supply the body with the materials it needs to rebuilt and repair cells you will have good health.

Re-examine your dietary habits — make sure your daily intake of food is nutritional. Slowly eliminate processed food (which is white flour and their products, french fries, cake, cookies etc.) and sugar from your eating habits. Now, you might say what’s left? There are many natural foods that are super in nutritional value and will do wonders for your muscle size and overall shape. It’s time you began to build a knowledge and understanding for good nutrition while you build your body. Be aware of the vitamins, minerals in food and what fantastic things these foods can do for you and your body.

Protein is the bodybuilding substance needed to form new tissues and cells and rebuild and repair old one. Your blood, tissues, organs, skin, hair, and nails are about 95% protein, along with your bones and nerves. Meat, fish, eggs and poultry are known as complete proteins. Others include soybeans, sunflower seeds, and peanuts. 60% of protein consumed is changed into sugar (glucose), that’s why sugar is completely unnecessary in your bodybuilding diet.

2/3 of your diet should be protein — the other third should be made up of fresh raw fruit, vegetables, nuts and seeds. Liver is the most effective source of complete protein. It’s the number on food that not only builds your body up, but greatly increases your energy. It relieves fatigue and neutralizes many dangerous drugs within your system.

Fat produces an energy reserve, slows down the rate at which food is digested and is a source of heat and energy, and a cushion for vital organs. Fish is practically a perfect food. It’s excellent source of high quality protein, vitamins and minerals. Eggs, are another superior protein food, 1-2 a day are recommended for everyone. They supply a full measure of minerals. True, they do contain cholesterol, but they are an excellent source of lecithin, inositol and many other effective cholesterol controlling agents. Powdered milk is outstanding because it consist of an abundance of fat free protein, vitamins and minerals. It’s known to rejuvenate the heart, brain, and verves and strengthens the failing body.

Natural carbohydrates invigorates the body and supplies is with warmth and vitality. The potato is not to be eliminated from your bodybuilding diet.

it has regenerative power

it’s a sweet that has natural laxative qualities

REMEMBER: It is not how much you eat — it’s what happens to the food after you have eaten it. Eating large quantities of food will not help your muscle building progress it it’s the wrong food!!

The true affects of Caffeine on our bodies

Caffeine is found in everything from face creams to coffee. But its effects aren’t yet fully known, reports Joanna Bounds.

We’re a nation of drug users. We take our first hit in the morning and many of us continue throughout our working day.

Addicts say they can’t function without their daily dose of caffeine. Globally, we consume 120,000 tonnes of the stuff each year, making it the most widely-consumed psychoactive substance in the world. And most of our caffeine intake comes in the form of a cup of coffee or can of cola.

And while caffeine consumption is deeply-entrenched in society, the “good” versus “bad” debate has been going on for centuries. This may be because caffeine has the same pharmacological effects on the body as many substances deemed harmful – although that doesn’t stop nine out of 10 people throughout the world using it regularly, say Alan Weinberg and Bonnie Bealer, authors of The World Of Caffeine (Routledge). high times There are many ways of ingesting our drug of choice. Besides coffee, tea and chocolate we can get our kicks from “energy” drinks and over-the-counter medicines. In the US there are caffeine tablets, caffeinated waters, and even lickable caffeine-infused lipsticks from US cosmetics company Hard Candy. Yet the effects of caffeine still aren’t fully understood.

“Caffeine’s effects on the body are complex,” says John Miners, professor in clinical pharmacology at the Flinders University of South Australia. “It affects the nervous system, the brain, the bodily organs, respiratory system and metabolic activity. But there’s still a fair amount of work left to be done on caffeine.” What is known for sure is that caffeine causes the body to release adrenaline, resulting in the “fight or flight” response, which enabled our hairy ancestors to run from sabre-tooth tigers. And, of course, gives you that morning buzz.

But, in the case of caffeine toxicity, it’s also been proven that it can be a killer. High doses of caffeine have resulted in roughly 20 deaths in Australia. The last fatality occurred a few years ago, when a 25-year-old woman collapsed in a bar after drinking a guarana-based tonic (which has since been taken off the shelves). Because the woman had a heart condition, she was careful to keep her caffeine intake low, yet the drink’s packaging did not indicate its high caffeine content.

“Some caffeine-based drinks are called “smart”, “happy” or “energy” drinks,” says Rebecca Smith, food policy officer for the Australian Consumers Association (ACA). “Others are marketed as a thirst quencher and are not the best way to rehydrate after exercise as caffeine inhibits the absorption of water.” The proliferation of such drinks has led to the Australia New Zealand Food Standards Ministerial Council forming a policy stating that caffeine cannot be added to any other products besides cola and energy drinks and those that do contain caffeine must be labelled clearly.

“There is no doubt that the concentration of caffeine in soft drinks and energy drinks has a marked pharmacological effect, which people need to be aware of,” says Professor Miners. “People monitor the amount of caffeine they drink but are unaware of the concentration of caffeine in other products. Energy drinks are the main area of concern.”

Even though death by coffee isn’t a concern for most of us, kick-starting the day with a large latte can lead to a caffeine addiction.

“Caffeine has the same sort of mechanism as cocaine or heroin, but
obviously with much less effect. This is part of the reason why people become
addicted to it,” says naturopath Ilana Lamont.

If you’re trying to kick the habit she advises weaning yourself off caffeine, rather than going cold turkey, and says withdrawal symptoms can include headaches, fatigue and depression. And it doesn’t take long for withdrawal symptoms to kick in.
“A lot of people get tired and depressed when they are coming down from the effects of caffeine,” says Lamont. “And that can be as soon a couple of hours after they’ve drunk their last coffee. Which is when they reach for the next cup. So it’s a vicious cycle.”
addicted to mug And be aware, says Professor Miners, that caffeine ffects people differently.

“In terms of effects on the body, and the rate at which it is eliminated, individuals handle caffeine in different ways,” he says.

“It’s influenced by factors such as age (children eliminate caffeine more quickly) and whether you smoke or not. Smokers eliminate caffeine at twice the rate of non-smokers. That’s why some people get heart palpitations and others don’t, and why it keeps some people awake but not others.”

And caffeine-induced insomnia isn’t urprising when you think that, if you drink a large cup of coffee at 3pm, 50 per cent of the caffeine will still be in your body six hours later. The reason it keeps you awake, says Lamont, is because the caffeine is stimulating your brain at a period of time when it’s not meant to be active.

Some people should avoid caffeine more than others. Pregnant women are especially at risk, as revealed by a study by Aarhus University Hospital in Denmark earlier this year. It showed that women who drink more than eight cups of coffee a day triple their risk of having a stillborn baby compared with non-coffee drinkers. A report in the Lancet Medical Journal also revealed that women who drink more than one cup of coffee a day are half as likely to conceive as those who drink less than a cup a day, as caffeine stimulates the production of chemicals in the body that slow conception.

user friendly But it’s not all bad news – caffeine does have ome positive effects too. Researchers at the University of Queensland have discovered that giving prematurely-born babies minute amounts of caffeine, rather than the drugs that are currently used, is a safer option when it comes to treating breathing problems.

Caffeine is also useful when it comes to the morning-after. A hangover equals a headache because alcohol enlarges the blood vessels in your brain. Caffeine does the opposite and constricts blood vessels, hence its use in over-the-counter painkillers.

It’s been proven that drinking a cup of coffee before exercising enables you to work out for almost a third longer. Plus, researchers at the Australian Institute of Sport have discovered that caffeine triggers muscles to start using fat as an energy source instead of carbohydrates.

So, is caffeine good? Or is caffeine bad? The solution to the onundrum, says Lamont, is to carefully monitor how much you’re putting into your body.

“Keep a log of how much chocolate, ola, coffee and tea you’re having each day,” she says. “Have a couple of cups of coffee a day, but not eight or nine, and drink lots of water to counteract its diuretic effect. Keep your intake to a minimum and you won’t be doing your body as much harm.”

beauty buzz As well as putting affeine into your body, the latest innovation is rubbing it into your skin. Facial toners, cellulite creams and body-contouring products now often contain caffeine, with companies claiming that it helps to firm and tighten.

French cosmetics company Clarins uses caffeine in some of its products, including face creams such as Contouring Facial Lift, and Shiseido’s celebrated anti-cellulite Body Creator also contains caffeine. The Fuji Spinning Company in Japan has even manufactured caffeine-infused underwear which, it claims, helps activate fat-dissolving enzymes.

Beauty insiders claim that caffeine-based creams work as diuretics, draining fatty cells of fluid resulting in firmer skin. But health professionals are dubious about the beauty benefits of the drug.

“It’s difficult to see the reason for including caffeine in beauty products,” says Professor John Miners.

And naturopath Ilana Lamont thinks it may just be another in a long ine of wonder compounds touted by cosmetics companies. “I can see no viable way that caffeine does anything,” she says. “I think it’s little more than the latest trend in the beauty world.”

How Effective are Your Nutritional Supplements?

Excessive weight gain is a big problem in America. According to the National Health and Nutrition Examination Survey, a publication of the Centers for Disease Control and Prevention, nearly two thirds of U.S. adults are overweight or obese. Most people want to do something about it, but don’t always make good decisions.

This year alone, fifty million people will go on some of form of weight-loss program, spending some $33 billion on weight loss products and services that are fad diets, unsafe or ineffective nutritional supplements. Countless others who have tried to lose weight and failed will give up altogether.

“What people need to realize is that there is no magic bullet when it comes to losing weight and keeping it off,” says Jeff Zwiefel, vice president of the Nutritional Products Division of Life Time Fitness, a national health, fitness, and nutrition company. “For many people, losing weight can feel like a daunting task. It takes a balanced approach that includes education, exercise and good nutrition, coupled with effective weight-loss supplementation.”

A good beginning point is to gain a better understanding of the mechanisms of weight gain. Do you ever wonder why some people can eat all the time and never gain weight while others seem to put on pounds at every sitting? “It’s all about metabolism,” says Zwiefel.

Simply stated, your metabolism is the way your body burns up all of the calories from the food that you eat and regulates energy. The speed at which your body burns up calories is called your metabolic rate. The faster your metabolism, the more calories you’ll burn, and the less likely that you’ll be overweight. “A small percentage of people naturally have a better metabolism than others, but for the most part, an individual’s metabolism is determined by their lifestyle”, says Zwiefel. So what can you do to place yourself in a better position to manage your weight?

Diet represents one of the primary ways to shed those unwanted pounds and keep them off. Although it might sound easy on paper to simply put less food in your mouth, the reality is that reducing calorie intake is a significant problem for most of us. It is more complex than just calories in and calories out. Factors such as stress and diet will dramatically impact how our bodies process the calories we consume. That’s why Life Time Fitness recommends you not only change what you eat, but your eating and lifestyle habits.

Instead of eating three meals a day — breakfast, lunch and dinner — eat five nutritionally balanced meals and two snacks per day. Spreading your food intake over the day is the best way keep your energy levels up and to burn calories for energy versus storing them.

You should also reduce the consumption of simple and refined carbohydrates that offer little nutritional value. Concentrate on eating foods that are high in fiber to reduce appetite and help reduce the risk of cancer. Look for good sources of protein throughout the day such as lean meats, fish, eggs, low fat dairy products, beans and nuts. Complex carbohydrates such as whole wheat bread, wild rice, whole-wheat pasta, multigrain cereal and potatoes are great ways to boost your energy level throughout the day. Eat 4-5 servings of fruits and vegetables; take a multivitamin with antioxidants each day to ensure you are getting the nutrients your body requires throughout the day.

Because our busy lifestyles can interfere with upholding the ideal dietary plan, proper supplementation can help fill in the gaps. However, there are dozens of supplements on the market today offering big promises. How do you know which brand is best for you?

“If a product promises, ‘effortless,’ weight loss, it doesn’t have your long-term health and wellness in mind,” says Dr. Bill Wheeler, Ph.D. and R.D., a former staff nutritionist to the President of the United States and independent consultant for Life Time Fitness. “Supplements need to be worked into your overall plan.”

Life Time Fitness’ LeanSource weight loss supplement is a patent-pending blend of four active ingredients shown in recent studies to help naturally speed up metabolism, burn body fat, and curb sugar cravings without the use of harmful stimulants. Unlike many other supplements on the market today that hype unbelievable before and after testimonials, LeanSource is based on real science and a proven safe and effective formulation. All Life Time Fitness nutritional products are regularly tested in independent lab settings to assure consumers they really contain what’s on the label.

Now available at Target, RiteAid, Kroeger, Kmart and Meijer stores, as well as Life Time Fitness locations nationwide and via www.lifetimefitness.com, LeanSource products are conveniently available in a gel cap form, bars, and ready-to-drink shakes in multiple flavors.

Good diet and the use of beneficial supplements are just part of the equation. Regular and balanced exercise is also a critical part of the process. “Just going to the gym once in a while isn’t going to cut it. You need to make a commitment, and stick with it,” says Zweifel.

Life Time Fitness recommends that people who are serious about shedding the pounds and keeping them off participate in aerobic training exercise regimens a minimum of three times per week for at least 30 minutes at a time. Aerobic exercises include brisk walking, biking, jogging, swimming, aerobic classes and dancing. Dieters are also urged to take part in resistance training exercises, such as weight lifting, at least twice a week for a minimum of 30 minutes per session.

South America’s Yerba Mate Gives All-Natural Energy Boost

Millions of Americans rely on coffee and sugary drinks filled with calories to get them started in the morning; but thanks to a movement that started in South America, Americans may soon be singing the praises of a different all-natural pick-me-up. Yerba maté, a tea-like beverage that has been popular in Argentina, Uruguay, Paraguay and Southern Brazil for generations, is starting to catch on in the United States.“I like it because it wakes me up without the nervousness and jitters I got from drinking coffee,” says Jamie Rosen, 39, a hairdresser from Scottsdale, Ariz., who was recently the focus of a feature Woman’s World story on yerba maté. Rosen discovered the tea “from a friend who recommended it for my health. After having my son I was not able to drop the weight I had gained and I was not accustomed to the extra weight.”Clinical studies have shown that caffeine-sensitive individuals generally have very positive results with yerba maté, made from the dried leaves of the “Ilex Paraguariensis” — an indigenous holly-like plant that grows wild in South America. Unlike coffee, yerba maté comes equipped with a wealth of nutrients to provide a broad range of vitamins, minerals and antioxidants to the body. Since pre-Colombian times, the native people of Paraguay have gathered the leaves to use them in their folk remedies and as a stimulant and restorative tonic. Yerba maté is widely regarded as an excellent appetite suppressor when consumed 15 to 20 minutes before meals which makes it an effective drink for weight loss. Yerba maté is also credited with improving energy levels and supporting the immune system.

“I have more energy and I’m more alert but without the negative side affects that I get when I use some other energy drinks,” says Rosen. “Then of course there’s the weight loss which has just been wonderful. I’ve gotten creative in preparing my yerba maté. The directions say to serve it hot or cold. In the summer I would put ice and a couple of scoops of the instant tea into a blender and make my own version of specialty blended coffee. I call it Blended Yerba Maté Royale.”Maté is most often consumed in tea bags that come in flavors including chai, vanilla, and mandarin orange. The most flavorful maté is sweetened with stevia, a natural sweetener. Instant dissolving maté is also a convenient and easy way to drink maté.

Traditionally, maté has been prepared in a gourd or mug and sipped through a bombilla (a filtering straw which extracts the most nutrients by pulling the water across the leaves) nestled into the herb. Hot — never boiled — water is poured to the top. The water will cause the leaves to swell and the water at the top of the gourd will look frothy and green, indicating its nutrient-rich properties. The gourd can be refilled five or six times until the green froth is gone, which means the leaves are depleted, and it’s time to refresh the infusion. Yerba maté can also be served cold as a refreshing sun tea.“I drink at least 16 ounces of yerba maté a day and I just love it,” adds Rosen.One of the main distributors of yerba maté tea in the United States is Wisdom Natural Brands, the distributor of Wisdom of the Ancients and La Merced, two major brands of maté.
