How to (and Should You) Use BMI to Determine Obesity

-->

BMI stands for Body Mass Index. It is a commonly used method of determining whether an individual is underweight, normal, overweight, obese, or extremely obese. It is nothing more than a special number that is calculated based on your height and weight (and nothing else), which you then look up on a chart. Your doctor may refer to it if you discuss your weight with him/her. It is almost certain that your health insurance company uses it. Even the Wii Fit uses it. This article discusses the steps to calculating your BMI, we well as more practical and accurate steps to take to determine if you are overweight or obese.

For those of you who like math, you can compute your BMI by taking your weight(in pounds), and dividing it by the square of your height (in inches). Then take that quotient, multiply it by 703, and note the result. That's your BMI score. Alternatively, you can use a chart like the one pictured above to determine this number.

Some charts are color-coded to immediately show you the category of your weight (overweight, obese, etc). If your chart does not show this then it will likely have the following legend that you can refer to for your BMI score: Underweight (Under 18.5), Normal (18.5-24.99), Overweight (25-29.99), Obese (30 -40), Extremely Obese (40 and higher).

That's it. You now have your BMI score, and what is supposedly means. It is worth noting several things, in an attempt to answer the "and should you" portion of this article's title. First of all, the BMI score is based on nothing other than height and weight. It doesn't take anything else into account, such as age, gender, body frame, body fat percentage, or muscular development. Many gold-medal-winning Olympic athletes are considered obese according to their BMI.

As a more practical step, if you want to categorize your weight, simply take off all your clothes, and look in a full length mirror. Turn all around, look at yourself from any and all angles, and make an assessment. You don't need any charts for this. Unless you are totally delusional, and are totally fooling yourself, you will simply be able to see what the situation is. If you are a professional athlete who is slim and muscular, you will see that. If you have a big beer belly, you will see that as well. If you are underweight, you will see that. Just look, and make a plan of action as need be, working closely with your doctor. Just be honest with yourself. If you see a big belly in the mirror, just accept that it isn't healthy, but you can do something about it, unlike people who have incurable medical conditions.

As the final step, if you are overweight or obese, and feel the need to assign a concrete number to your condition, the best thing to do is have your body fat percentage calculated. You can get a rough idea of this by using a simple, low-cost device that sends a mild current through your body which you do not feel at all. You need to follow the instructions carefully, and use it under appropriate conditions to not get a false reading. It is still not totally accurate. You can have your percentage calculated more accurately by having a professional use skinfold calipers to measure it. Finally, you can have your percentage calculated by doing hydrostatic weighing. This requires a facility that has a special weight tank that you must immerse yourself in.

Keep in mind that if you are overweight, you will know if you are losing weight based on looking in the mirror, and of course by using a simple scale. You will also know it by the way that your clothes feel, or by how many notches on your belt you are using. We do not need to be so dependent upon special methods, especially oversimplified and generic charts, to tell us such obvious things about our health.

High Blood Pressure? Natural Alternatives Can Help!

High blood pressure (hypertension) is a dangerous condition that can lead= to stroke, enlarged heart, congestive heart failure, kidney and eye damage, atherosclerosis hardening of the arteries, and premature death.
According to a recent report released in The New England Journal of Medicine of 16,000 adults surveyed over the age of 24, nearly 30 percent had blood pressure of at least 140/90 and more than one-third of them were unaware of their condition.
Blood pressure refers to the force of the bloodstream against the walls of the arteries as they deliver blood from the heart to the rest of the body. Normal, healthy blood pressure ranges from about 110/80 to as high as 140/90. The higher number refers to systolic pressure, which is the hearts contractions. The second number, the diastolic pressure, measures the rests between heartbeats. Here are the categories to consider when evaluating blood pressure:

• Normal - Less than 140/90
• Borderline - 141/91 to 159/94
• High - 160/95 or more

What Causes High Blood Pressure?
Although there are still questions about the roots of essential hypertension, many researchers name two culprits: The typical American diet and lifestyle factors. Following are 9 major factors that can contribute to this potentially deadly condition:
1. High-fat, high-sodium diet . . . Interestingly, vegetarians who normally eat a low-fat, low-sodium diet have a profoundly lower incidence of hypertension than non-vegetarians.
2. Fat imbalance . . . Too much saturated fat in the diet. We need more essential fatty acids to help clear the system of fat solids.
3. Nutritional deficiencies . . . People whose diets are low in potassium, magnesium, calcium and vitamin C are at greater risk of hypertension.
4. Obesity . . . High blood pressure is almost six times more common among overweight people ages 20 to 44, and twice as common in those 45 to 74
5. Smoking . . . Chronic smoking decreases blood flow to the brain, increasing the risk of stroke.
6. Alcohol . . . Heavy drinking is another indicator of high blood pressure.
7. Stress . . . In many instances, stress can be the major factor causing high blood pressure.
8. Atherosclerosis . . . A buildup of fatty deposits can narrow the blood vessels, leading to a rise in blood pressure. The increased resistance means the heart has to work harder to pump blood through the body, placing it under strain.
9. High sugar intake . . . People who had more sugar in their diet had markedly increased blood pressure.
Anti-Hypertensive Diet Guidelines
The following recommendations can help you keep your blood pressure at healthier levels:

• Follow a low-fat diet.
• Increase your intake of potassium, magnesium and calcium.
• Reduce your intake of salt.
• Restrict your consumption of refined sugars.
• Exercise more often. Since excess body fat is a primary risk factor in hypertension, it is critical to maintain a healthy weight. The importance of regular exercise cannot be over-emphasized.

Essential Nutrient Intake
What you eat has a powerful influence on your blood pressure as well as almost every other aspect of your health.
For most people, the sodium/potassium ratio is more significant than sodium alone. We should be consuming about five times more potassium than sodium (5:1), but the typical American diet includes half as much potassiumas sodium (1:2).
By eating more POTASSIUM-rich foods, you can reverse the ratio and promote healthy blood pressure. Foods such as bananas, oranges, tangerines, beans, dried peas, and potatoes provide a wealth of natural potassium.
MAGNESIUM is another vital nutrient for blood pressure. It is believed that magnesium activates the bodys cellular membrane pump, which pumps sodium out and potassium into the cells. Some clinical trials have shown that magnesium supplementation reduces blood pressure. Magnesium- rich foods include nuts (especially almonds, cashews, and pecans), rice, bananas, potatoes, wheat germ, kidney and lima beans, peas, soy products, molasses, oat, bran, and fish.
CALCIUM is important. People with high blood pressure are advised to increase Calcium intake and to eat more calcium-rich foods such as nuts, salmon, sardines, low-fat dairy foods, watercress, kale, broccoli, turnip greens, collard greens, and mustard greens.
Here is a list of other nutritional supplements that can help prevent high blood pressure:

• HAWTHORNE is an herb that has been shown to widen blood vessels, especially the coronary arteries.
• CAYENNE reduces the risk of atherosclerosis, which can lead to hypertension.
• VALERIAN has sedative activity, which has a beneficial effect on blood pressure.
• VITAMIN C supplementation has exerted a valuable blood-pressure-lowering effect in people by promoting the excretion of lead, which is linked to hypertension.
• COQ10 shows promise for hypertensives. Coenzyme Q10 is a nutrient that naturally occurs in our bodies and can be supplemented to assure adequate daily intake.
• GARLIC helps reduce cholesterol as well as blood pressure.

Summary . . . The consequences of untreated high blood pressure are too serious to go untreated. By making smart choices about the foods you eat, the intake of beneficial nutritional factors and your exercise regimen, you can help control your own blood pressure.

Obesity in America -- The Growing Epidemic!

Obesity is a disease that affects approximately 60 million people in the United States, where women are especially affected. Over one-third of women between the ages of 20 and 74 are obese, the majority of them being African American or Mexican American. With more and more pre-packaged food and less and less activity, the number of obese people in America has steadily increased since the 1960’s.

But what is obesity? Many people think obesity means that a person is overweight, but that’s not exactly true. An overweight person has a surplus amount of weight that includes muscle, bone, fat, and water. An obese person has a surplus of body fat. Most health professionals concur that a man is obese if he has over 25 percent body fat, and a woman is obese if she has over 30 percent. Women physiologically have more body fat than men, so that why there’s a difference in percentage.

It is difficult to determine the exact percentage of body fat a person has, but estimates can be made in a number of ways. First, using a tweezer-like tool called a caliper, you can measure the thickness of skin folds on different points of your body and compare the results with standardized numbers. You can also use a small device that sends a harmless electrical current through your body and measures your body fat percentage. The most commonly used method to determine if a person is obese is to look at his/her Body Mass Index (BMI). A person with a BMI over 30 is considered to be obese, and a BMI over 40 is considered to be severely obese. It’s important to remember though that BMI could be misleading in pregnant or lactating women and in muscular individuals. There are some free tools to find your body fat percentage at http://www.abs-exercise-advice.com/body-fat-calculator.html.

With obesity, comes the increased risk of diseases such as high blood pressure, Type II Diabetes, heart disease, and breast, colon, and prostate cancer. In addition, obesity has been linked to mental health conditions such as depression or feelings of shame and low self-esteem. Health experts say that even losing 10 to 15 percent of your body weight can dramatically decrease the risk of developing these serious conditions. In addition, many obese people are discriminated against and targets of insults and other verbal abuse. Find out if you are at risk for health disease using the health calculators at http://www.abs-exercise-advice.com/high-blood-pressure.html.

A number of factors, such as poor diet, lack of physical activity, genetics, and certain medical disorders, cause obesity, but it can be conquered. One major obstacle to being more physically active is motivation and accountability. Find a friend with similar fitness goals and begin a simple exercise program together. It takes time to see the results, but your health is worth it!

South Beach Diet - Ready to be a Loser?

The South Beach diet is a way that many people are shedding the pounds. Miami cardiologic Arthur Agatston started this diet. It got its name when it became a very popular diet in South Florida. This diet is unique from many diets because it evolves. Instead of simply having a diet list that remains the same throughout the course of the diet, your requirements change in stages.

When you first start the south beach diet, it is much like every other diet. You cut out all those things in your diet that most people live for. Sweets, breads, carbohydrates, alcohol, and even fruits are forbidden. Unlike most diets, however, this phase is only supposed to last for two weeks. This is why it is usually seen as healthier than a no-carbohydrate diet. While no carbohydrates will certainly make most people lose weight, it isn't healthy for the long run. You need these for energy and a healthy body.

After two weeks of torture with a south beach diet, you are allowed to have your forbidden foods back, but not in the same way as before. The hope is, that as you go through this diet plan, you will learn what foods are truly good for you. There are some fats and carbohydrates and even sweets that your body should have. A healthy body is well balance. The challenge is to find that balance.

When you add your foods back into your diet, you are supposed to do this step in a slow and healthy way. When you get through adding all of your loved foods back into your diet, hopefully you will have learned how to eat normal size portions. Many people eat otherwise healthy foods, but in too large of portions.

You will also have learned how to balance your diet so that you take in everything you need without overdoing anything. Advocates of the south beach diet conclude that you don't go without anything your body needs.
You only get rid of those things such as carbohydrates and fats that are bad for you. The fats and carbs that are deemed good will stay in your long-term diet.

The south beach diet is supposed to become a lifelong way of eating after you make the steps to eat this way. And if it gives you the body image that you are seeking, who would really quit it? And on top of a positive body image, your doctor will also be proud of you for adopting a healthier lifestyle.
