Though one of the most popular tools used today to determine whether someone is at a healthy weight or not is the BMI, body fat and lean muscle tissue don’t figure into the equation. This has led many experts to discount BMI as an archaic measurement that isn’t accurate for many people. What is BMI, and why is it a good measure for some, maybe, and completely wrong for others?

BMI, or body mass index, was created in the early 1800s by Adolphe Quetelet. Because of that, it’s sometimes called the Quetelet index. It’s nothing more than a way of comparing a person’s weight to his or her height, and determining if his or her weight falls into a healthy and normal range. The BMI is still used today pretty much as it was when Quetelet invented it.

The formula for figuring BMI (body fat, bone and frame size, muscle and body type aren’t included in that) is this: Take your height in meters squared (your height times itself) and divide your weight in kilograms by that number. For example, if I’m 5 feet tall, that’s about 1.5 meters. To square that number, take 1.5 times 1.5. The result of that is 2.5. So if I weigh 120 pounds, that’s about 54.5 kilograms. Divide 54.5 by 2.5 and I get 21.8 as my BMI. The normal weight range is from 18.5 to 24.9, so 21.8 is classified as a normal weight. Underweight is considered 18.5 and below, while overweight people will calculate a BMI of 25 to 29.9. A BMI of 30 or greater indicates obesity.

BMI, body fat and general health can all be used as signs of how fit a person is. But where general health is pretty self-explanatory and the percentage of body fat clearly shows whether a person gets enough exercise or not, BMI is a bit trickier.

People with a lot of muscle don’t show accurate BMI readings. Because muscle weighs so much heaver than fat but takes up less space, a relatively small statured person can carry a lot of muscle weight without looking huge. BMI doesn’t take that into account. Football players, professional wrestlers, bodybuilders, and virtually any athlete who has a lot of muscle is going to measure as overweight and even obese according to the BMI. So it’s not accurate for them. Is it accurate for everyone else?

The answer to that is yes, and no. It depends on you. The BMI typically doesn’t show an accurate result for children. And extremely tall or large-framed people will show overweight or obese classifications more easily because of the extra weight from their bones and muscles. So for very short, tall or muscular people, the BMI appears to not be a good tool.

There’s also no distinguishing between men and women in the BMI. Body fat is more natural for women who are supposed to have more than men, so some sort of distinction in the measurement of the sexes would help the BMI’s accuracy

Gastric Bypass: What You Need to Know Before You Go Under the Knife

Tired of all your weight loss methods that dont work? Surgery may be your only lifesaver. In fact, some overweight people go to greater lengths by going under the knife to be able to lose weight fast. You might want to consider gastric bypass surgery to eliminate those unwanted bulges and flabs. In essence, it lowers the volume of the stomach by as much as 30 ml. This procedure, which is sometimes referred to as bariatric surgery, is the most preferred weight loss surgery by surgeons in the United States.

It is because this type of bariatric surgery is much safer and less risky than other weight-loss procedures. Compared with the other type of bariatric surgery (gastric banding surgery), this procedure does not easily lead to weight gain. And with consistent changes in a patients lifestyle and behavior, the surgery can result in a long-term and immediate weight loss, as well as other health benefits such as treatment of sleep apnea and type II diabetes.

How safe it is?

The technology used in the weight loss surgery makes the operation much safer than before. Majority of bariatric procedures take advantage of the new laparoscopic technology, which uses a tiny video camera and other instruments to make very small incisions on the abdomen. Whereas before, surgeries of the stomach involved creating large incisions that usually caused intense pain and inflammation to patients. Smaller incisions using the laparoscopic technique leads to less pain, less swelling, fewer scars, and faster recovery rate.

How does it work?

Usually performed within two hours, the surgery involves making the stomach smaller by creating a line of staples that is joined to an end of the small bowel.

Is this surgery right for you?

It depends on your body mass index (BMI). You are a candidate for the surgery if your BMI is not less than 40. But if you have any serious disease such as pneumonia, bronchitis, or diabetes, your BMI must be at least 35 in order to undergo a weight-loss surgery. Otherwise, the surgeon may not allow you to go through the procedure because of the complications. Aside from the right physical condition, you must be emotionally and mentally prepared for the surgery. For the operation to be successful, you should be properly motivated and aware of the risks or complications that may arise. Also, surgery should always be the last resortmeaning you use it only after you have tried dieting and exercise but to no avail.

What are the risks?

Of course, any kind of surgery entails some risks due to the incisions involved in the operation. Deaths resulting from the surgery are very rare (about 0.1 to 2 percent). The complications of the surgery are bleeding, respiratory dysfunction, stenosis or the obstruction of stomach, and leaking due to the staples.

How to find the right surgeon?

Choosing the best surgeon is one of the most important decisions to make when it comes to weight-loss surgery. The surgeon is the only person to entrust your life and limb with, so to speak. So he or she must not only be competent, but also a person whom youre comfortable dealing with. Also, look for a surgeon with a vast experience in gastric bypass surgery, preferably someone who has performed hundreds of operations. That way, you can be sure that your surgery is safe and effective.

A weight loss calculator can be a great motivational tool if you look at it with the right attitude. Whether youve got 10 pounds to lose or 200, punching in the numbers and coming up with goals and time lines can help focus you to the task ahead. In fact, a calculator is just one of the tools you can use to help keep you losing weight and getting healthier without getting burned out or quitting because you dont know what to do next.

The Internet contains every kind of weight loss calculator you can think of. You can calculate your BMI, or body mass index. By entering your height, weight and approximate level of activity, youll get a BMI number. This number determines whether youre about normal, overweight or obese. The lower the number, the better, though it does point out the numbers than mean a person is underweight, too.

The BMI calculator is one of the most common youll find, and one of the easiest to use. While youre losing weight, it can also be fun to punch new numbers into the weight loss calculator from time to time to watch the BMI number go down. Especially satisfying is the day when your number moves from the obese range to the overweight range, or from overweight to normal!

Other types of planning and motivational tools youll find on line are calculators for things like figuring your daily caloric needs. These can be used in a variety of great ways to help you lose weight. First, figuring out how many calories you need a day just to maintain your weight is one of the best things you can do when you plan to drop some pounds. Everyone, whether they want to lose weigh or not, should know about how many calories they should eat in a day, just for general health.

One youve used the weight loss calculator figure your daily calorie needs, if youll subtract 500 from that number and stick to the plan, youll lose on average 1 pound a week. Subtract more calories to lose more, without going below 1500 or 1600 calories. Most people need at least that much for proper nutrition and health. If youre extremely short and small boned you could probably go lower; but not by much. Remember, under eating to lose weight pretty much guarantees youll gain it back as soon as you eat normally again.

Another type of weight loss calculator that can be incredibly motivating can be found online, too. You enter your weight, and your goal weight, and it calculates about how many calories you should eat per day to reach that weight by your specified date. Most will even warn you if your date is too ambitious, and that it would be hard if not impossible to achieve the goal by that date. Some let you enter your goal, and they give you a date. This lets you use a weight loss calculator to plan and monitor your success.

Healthy Living: Simple steps to a better life
Colin McDougall

When you watch TV or read magazines you get the impression that most people spend their days as lean, mean exercise fanatics who compete in triathlons, eat tofu, and drink a gallon of rain water a day.

If you dont fit this profile, you are not alone. Consider:

Seven out of 10 American adults don’t exercise regularly, despite the proven health benefits, according to a 2002 study based on more than 68,000 interviews for the National Center for Health Statistics.

80 percent of people in the US older than 25 are overweight based on the body mass index (BMI), a national guideline computed through a combination of weight and heightaccording to a Harris Poll released in 2002.

According to the American National Center for Chronic Disease Prevention and Health Promotion (CDC), in 2000 the most common actual causes of death in the United States were tobacco (435,000), poor diet and physical inactivity (400,000), alcohol consumption (85,000).

The writing is on the wall poor diet and physical inactivity is about as dangerous as smoking.

So, why dont we exercise and eat right?

For most of us, the answer is: time. Exercise and diet take time away from our work, our families, our lives.

Some of us have tried to fit exercise into our daily routines before and maybe even stuck with a program for a while, but finally saw too little gain for the effort and time it took.

Heres the good news: a healthy lifestyle wont consume you like it might have years ago. The science of healthy living has come a long way in recent years. Consider:

Modest but regular exercise has proven to raise the bodys metabolic rate, so that you burn fat even when at rest.

New strategies of exercise and diet bring results much sooner than ever before, without drugs.

A healthy lifestyle isnt only about working out and cutting out foods you like. Its also about applying a balanced approach to all areas of your life. For example, studies show that you can lose weight by simply watching less television.

Realistic health improvement for real people

We all know we should take better care of ourselves, but modern lifestyles with hectic work schedules, commuting, and family and social responsibilities make it difficult for us to live a healthy life.

But you can begin to live a healthier life. You can start slowly and work in more healthy practices. Interestingly, even small changes can lead to big improvements over time. Begin modestly by making a commitment to starting to do something and to stay with it. As you proceed, remember to be proud of your accomplishmentsyou will be doing more than 70 percent of the population!

The doctor will see you now

Before embarking on a fitness program and making dietary changes, talk with your doctor about your plans. If you have prior health conditions, especially cardiovascular disease, your doctor may want you to avoid certain exercises. If you are on certain medications, your doctor may give you valuable information on avoiding drug interactions with certain foods such as grapefruit and with some herbal supplements.

A special word to smokers

If you smoke, you know you need to quit. Modern research links smoking to a vast array of cancers, as well as heart and cardiovascular disease. According to the American Cancer Society, smoking alone causes one-third of all cancer deaths.

The bottom lineif you are a smoker, stopping represents the single best health action you can take. Talk with your doctorthere are new treatments available.

Some basic health objectives

It can be hard to know where to start when you want to improve your health.

Here are three baseline objectives for a healthier lifestyle:

Lose weight / Eat a more balanced diet

Get more exercise

Reduce stress

Lose weight / Eat a more balanced diet

Qualified health professionals agree the keys to losing weight are to eat less, eat a more balanced diet, and to increase your exercise level. In general, reducing your intake of protein and eating more fruits and vegetables is a good start. Try and reduce your intake of saturated fats common in fried foods. Your heart will thank you.

Here are some tips:

Eat a diet that contains lots of:

Whole grains

Fruit

Vegetables

Ensure you are getting an adequate supply of:

Vitaminsa daily multi-vitamin is good protection

Calciummany men and women do not get enough calcium in their diets, putting them at risk for osteoporosis.

Watermany adults do not consume enough water each day

Reduce your consumption of:

Fat

Sugar

Salt

Processed foods

Fast food meals

Alcohol

Other Tips:

Make your own nutritious lunch and take it to work. Youll save money and feel better too.

Buy veggies for snacks, such as small washed carrots or apple slices, which you can put into re-sealable bags and take to work.

Consider diet supplements for weight loss and health

Despite our best efforts, it is hard to eat a balanced diet everyday. Consider taking one or more of the excellent vitamins and supplements available, but check with your doctor first before taking them.

Today, you can get the latest high quality vitamins and dietary supplements at low prices and without leaving your home by ordering over the Internet. Here is an excellent example of a vitamins site.

Avoid fad diets

Use common sense and follow the advice of government health authorities, university nutritionists and other well-accredited health care experts. Reliable nutrition advice is available free by contacting your local health department and talking with a nutritionist.

Be wary of the latest Fad Diets put forward by authors. Healthy eating is not rocket scienceyou need to eat a balanced diet that includes the four food groups:

Vegetablesthree or more servings per day

Whole grainsfive or more servings per day

Fruitthree of more servings per day

Legumestwo or more servings per day

This is well documented by decades of research. Sure, the fad diets may help you lose weight temporarily but at worst you could seriously damage your health and at best, you will likely gain the weight back if the diet is not sensible and sustainable.

Get more exercise

The second key to losing weight is to add more physical exercise into your lifestyle.

Exercise takes some effort and time, so it is fair to ask why you should bother. The key reasons include the following:

Weight loss

Reduced risk of heart disease and stroke

Increased energy

Increased bone strength

Maintenance of muscle mass

Reduced stress levels

Better appearance

Research continues to show that any exercise is better than none. For example, regular walking or gardening may be beneficial in reducing your risk of heart disease.

Exercise

At a minimum you should strive for at least three 20-minute bouts of continuous aerobic (activity requiring oxygen) rhythmic exercise each week.

Other exercise levels will depend on your physical condition and goals. Consider a session or two with a certified personal trainer to accurately assess your current physical condition and plan an exercise regimen.

Easy ways for non-athletes to add exercise to their daily lives:

Get off the bus a stop or two early and walk to work or home.

If you drive to work, park in a new location and walk a few blocks.

Take the stairs at work. Get off the elevator a few floors down and walk up a few flights.

Ride a bicycleyou dont need a fancy bike, but you should always wear a helmet

Walkits cheap and it works! The average person can walk three to four miles an hour. This makes many short trips to the store within walking distance, saving you money on gasoline and providing a health benefit at the same time.

Try gardeningraking, weeding, and tilling will all give you exercise. If you have a small, level yard, consider a push mower. These mowers are quiet, cut the lawn beautifully, and give you exercise all at the same time.

Enlist a friend to join youhave fun together and stay motivated

Consider creating a home gym

More and more people are purchasing exercise equipment to use at home. The advantages include:

No wasted time traveling back and forth to the gym

Ability to use the equipment more often and at more convenient times

Increased chance of participation by all family members

Here are some tips in selecting equipment:

Determine what goals you want to pursuestrength training, aerobic training or cardiovascular training before you look at equipment.
Buy sturdy, quality equipment from known manufacturers.
Purchase equipment that will meet your needs now and as you improve
Buy from a reputable retailer, who has a large selection, low prices, and stands behind their products. For an excellent example for home gyms (click here) and other fitness equipment.

Reduce Stress

The good news is that by eating a healthier diet and exercising more frequently, you will have already taken two of the most important steps to helping your body fight stress.

Obviously sources of stress are a personal matter. Be alert to chronic stress you have trouble managing. This can sometimes lead to more serious conditions for both men and women, such as depression. If you feel you are having trouble coping, it is best to talk with your doctor.

If on the other hand, you have the everyday level of stress most of us face, you may want to try these stress-reducing tips:

Make time for family and friends

Avoid stressful thoughts by not listening or watching the news first thing in the morning and last thing at night

Try listening to music or practicing meditation

Take vitamins B6 and B12they are excellent for fighting the effects of stress and most adults dont get enough of these important vitamins.

How can I get started on a healthier lifestyle?

If you are not living as healthy a life as you want right now, you may be wondering how you will find the time and the resources to make changes.

The good news is you dont have to make all the changes at once, but do resolve to make some improvements. Time is always an issue, but time taken to improve your health will yield big improvements in many other areas of your life.

There has never been a better time to start, because thanks to the Internet you can purchase quality heath care products and equipment, quickly and efficiently and save money too! Heres a link to get you started with weight loss programs and healthy living.
