Your Accurate Body Fat - What Is It And Why Is It Important?


If you want the most accurate, technologically advanced, easy to use, and non-invasive body composition assessment available, then the BodyMetrix ultrasound scanner is the new state of the art device you're looking for. It's as easy as using a few drops of ultra sound gel on the hand-held scanner. No pinching like the typical calipers that have been used for years. In fact, the BodyMetrix is so easy and accurate to use the main reason you don't see it in widespread use yet is the initial cost of the device.

I'm sure many women have experienced the use of ultrasound. It's painless and can provide a lot of vital information. In this case, the ultrasound waves rebound off different muscle sites giving you exact measurements in millimeters. Your thickness of adipose tissue (fat) is measured subcutaneously for each measurement site. Ultrasound bounces sound waves through dividing lines of fat, muscle, and bone which is extremely useful. Remember that muscle is metabolically active, so the more muscle you are able to build the more calories you will burn around the clock. When you have an accurate level of fat and increased muscle you can improve your health and optimize your performance.

Frankly, weighing yourself doesn't tell you if you've lost fat or muscle. Also, skin-fold measurements can be very unreliable because of fat underneath the skin and the skill level of the practitioner taking your measurements. Since your muscle is metabolically active, you do not want to lose lean muscle. You want to preserve muscle and continue to build muscle to burn more calories while remaining fit and strong. The BodyMetrix helps you to track whether you are making real improvements in your health or just losing vital lean tissue.

The Bodymetrix software allows you to track your progress over time to see if your training and nutrition is effectively working. Your calorie needs are calculated including your BMR (Basal Metabolic Rate) with the option of including exercise or not. There are 3 types of body choices you can use for measurements: athletic, non-athletic, and elite. The non-athletic body type will find the BMI (Body Mass Index) useful in determining a healthy waist to hip ratio, but the athletic and elite body types will want to use the lean mass to fat mass differences to improve health and optimize performance.

There are primarily 3 top body fat measurement devices: the DEXA (X-ray absorptiometry), BodPod (air displacement), and BodyMetrix (hand-held ultrasound). The DEXA is a $20,000 machine which unfortunately emits radiation. The Bod Pod is also extremely expensive around $25,000+, but the BodyMetrix Ultrasound machine is just as accurate as the DEXA and Bod Pod machines yet a fraction of the cost usually running around $2,000.

This is the most accurate portable device available and is the ideal way to assess and monitor your body fat levels. Ultrasound measurements offer 3 great benefits:


Simple, quick, and comfortable to operate.
Is not affected by hydration levels, exercise, or caffeine intake.
The BodyMetrix will detect the true fat thickness at each measurement point

If you have the opportunity to use the BodyMetrix technology you will appreciate the ease of use. Yet, more importantly the data that you collect and apply will provide a baseline for seriously improving your health and fitness. You will have the capabilities to monitor, measure, analyze, and record body fat and circumference measurements. You can even scan a specific site and compare those scans on a quarterly or semi-annual basis. The customize reports include: body fat percentages, weight, BMI, BMR, recommendations, disease risks, weight and body fat trends, and thickness point trends. Your BodyMetrix ultrasound device will elevate your health and help optimize your performance while helping you to achieve your goals.

Detecting Osteoporosis Early Is Very Important


Men and women suffer from osteoporosis. It can be prevented and treated, but it is often called the silent disease because bone loss occurs without symptoms. You may not know you have osteoporosis till your bones become so weak that a sudden strain, bump or fall causes a fracture or a vertebra to collapse.

Early diagnosis is the key to prevent osteoporosis. Unfortunately, people believe they need not worry about osteoporosis until they are old. Many people in their early forty's and less are now victims of this debilitating disease.

Estimation:

The national osteoporosis foundation of USA estimates that by 2035, countries like India and China will have the largest osteoporosis population in the world. One out of every two women and one in eight men over the age of fifty will have an osteoporosis related fracture in their lifetime.

The older you are, the more you are at risk of developing osteoporosis, as your bones become weaker and less dense as you age. Family history can also play an influential part in developing osteoporosis. Susceptibility to fracture may be, in part, hereditary. People whose parents have a history of fractures also seem to have reduced bone mass and may be at risk for fractures. Small, thin-boned women are at a greater risk of developing osteoporosis. Your chances of developing osteoporosis are greater if you are a woman. Women have less bone tissue and lose bone more rapidly than men because of the changes involved in menopause. Asian women are at a higher risk of developing osteoporosis as compared to African, American Russian and Latino women.

Detecting osteoporosis:

The DEXA (Dual-energy X-ray Absorptiometry) Bone Densitometry Scan in considered the gold standard in accurate and reliable diagnosis of osteoporosis. A fast simple examination, it is non-invasive, has minimal radiation exposure, high reproducibility and can measure bone mineral density at multiple sites.

The results of the DEXA bone density scan can:

a. Detect low bone density before a fracture occurs.

b. Confirm an osteoporosis diagnosis if you already have a fracture.

c. Predict your chances of fracturing in the future.

d. Determine your rate of bone loss and or monitor the effects of treatment if the test is conducted at intervals of a year or more.

Other methods of detecting osteoporosis include:

The Quantitative Computer Tomography, QCT, The Quantitative Ultra Sonography, QUS,. The QCT cannot take measurements of the hip. It has a high radiation doze and is costly. The QUS is inexpensive, radiation free and a very quick way to measure bone mass density. But due to poor precision, it must be complimented with DEXA scan before commencing on any long term treatment.

Detecting osteoporosis through X-rays is usually a subjective assessment, and the diagnosis cannot always be relied upon.

Bone Density - How Important is It?


Bone density has not been talked about very much until the last 5-7 years. However, today startling facts have come to light. One in 2 women, and one in 4 men,over the age of 50, will break a bone due to osteoporosis. Pretty scarey when you see statistics like that.

So, what is Osteoporosis and is it really such a big deal? Osteoporosis is a progressive bone disease in which the density of the bone is decreased & the structural integrity of the bone is impaired, thus making the bone more brittle. The cortex, or outer portion of the bone, becomes thinner and more porous, thus making it more prone to fractures. This disease affects 75 million people in the United States, Europe, and Japan. It is known to cause at least 1.3 million fractures each year in the U.S. alone. Since the disease often shows no symptoms, many people do not know they have it until they actually break a bone.

Now, that we see how important bone density is to our health, just what can we do to protect our bone health or even improve it? You should start with a sit down visit to your physician. They will begin by taking a look at your diet and your lifestyle. A good healthy diet with adequate calcium and Vitamin D can help to keep your bones strong. Bones store extra calcium for basic body functions. However, when we don't get enough calcium our body robs our bones of this calcium and it makes our bones weaker. Talk honestly to your Doctor about your diet and possible calcium supplements. You should also think about increasing your activity level. Exercise, especially weight bearing exercise, is proven to increase your bone strength and bone density. It can also help your muscle strength which takes pressure off your bones. Another important fact; Smoking, excessive alcohol intake, and also phosophoric acid from carbonated beverages, have all been shown to decrease the calcium in your bones. There is a lot you can do to help protect your bones and your health the natural way.

Your Dr. will next recommend that you have a Bone Density Test. This a simple, painless procedure usually performed in the X Ray Department. It can help the Dr. diagnose osteoporosis in the earliest stages. The test is a major predictor of the strength of the bones and how they can withstand stresses. If your bone density is reduced by a significant amount then you are considered to have osteoporosis.

The most common test to measure Bone Density is called the DEXA Scan. It takes xrays using a minimal amount of radiation, of the lower spine, hips and perhaps the hands and wrists. This test compares your bone density levels to those of a healty young adult. Anything above a Minus 1 is considered normal bone density. For those within the -1 to -2.5, you are depleting your bone mass. Below the 2.5 level you are considered to have osteoporosis. Doctors recommend all women over the age of 60 to have a DEXA scan, and all men over 70. The disease is especially prevalent in this age group. Some younger patients with a family history of osteoporosis may need to followed closely and have a DEXA scan sooner.

For patients who are diagnosed with Osteoporosis there are many options for treatment. There are several medications on the market that have proven very effective in combating the disease. Also, there is more information than ever out there regarding better diets, different exercise methods, etc. All these things are vitally important in helping you to stay healthy and protect your bone density.

Osteoporosis - Why Is It Important


Osteoporosis is a chronic condition of the bone where the bone mineral density is lower and the micro-structure of the bone is disordered making the bone weaker. Osteopenia is a thinning of the bone, but not severe enough to meet the criteria for osteoporosis. Bones which have lost their mineral density are at higher risk for fracture.

Bone density scanning, also called dual-energy x-ray absorptiometry (DXA or DEXA) or bone densitometry, is a special form of x-ray technology that is used to measure bone loss. DEXA is considered the standard for measuring bone mineral density.

The T-score is the most significant scoring system in postmenopausal women and reflects a patient's bone density compared with healthy, white women between the ages of 20 and 29 years of age. T-scores less than or equal to -2.5 at the hip, femoral neck, or lumbar spine are diagnostic of osteoporosis.

In the past our concern has been primarily on the loss of bone density in women. Osteoporosis was primarily a concern in postmenopausal women over age 50. It is now known that some men experience a decline in their bone mineral density as they age, if they require chronic use of corticosteroids, or suffer hypogonadal conditions.

Prevention is the most important way to reduce the risk of osteoporosis related fractures. Bone mass density peaks between 25 and 35 years years of age. Physical activity during your teenage years has the greatest impact in reducing your risk of osteoporosis later in life. In adults physical activity can help maintain and actually increase bone mass density. The higher the peak value of your bone density at age 25 the lower your bone loss will be as you age.

A loss of bone density occurs due to an imbalance between bone resorption (which normally occurs) and bone formation. In someone with a decline in their bone density, bone is reabsorbed more quickly or it is formed at a slower rate than necessary to prevent a decline in bone density. Many cases of osteoporosis do not result from inadequate calcium intake, but from other factors such as cigarette smoking, sedentary lifestyle, family history, age over 30, and complications related the use of some medications.

The risk factors that cannot be changed include a family history, a history of a bone fractures as an adult, advanced age or European or Asian ancestry. The risk factors that you can change include prolonged use of corticosteroids, smoking, low body weight, low calcium and Vitamin D intake, alcoholism, sedentary lifestyle and poor health.

Restoring the micro-structure of the bone can be difficult once you start experiencing a decline in bone density. Trabecular and cortical are the two types of bone. Trabecular bone appears sponge-like and is at the core of long bones while the cortical bone is the hard exterior shell. When a decline in bone density begins it is the trabecular bone that demonstrates the most bone loss. The hip bone, spine and wrists are the areas of the body which have the most trabecular bone and are at the greatest risk for a loss of bone density and osteoporosis related bone fractures.

If you have suffered a bone fracture, related to osteoporosis, you are at higher risk for subsequent fractures. It is estimated that about 20 percent of those suffering a hip fracture die within a year. The risk of death is usually related to other complications associated with osteoporosis and fractures. A hip fracture will often result in decreased mobility and an additional risk of pulmonary embolism. A Pulmonary embolism is a blood clots that travels to the lung and obstructs blood flow. The blood clot usually originates in the lower extremity of someone suffering a fracture or injury to the lower extremity. The consequences of the embolism can be chest pain, respiratory distress and even death.

Osteoporosis also affects the spine, resulting in an increase in curvature. This increased curvature may affect your ability to breath appropriately and increase your risk of falling. Compression fractures of the spine can result in severe pain, and prolonged hospitalization.

Osteoporosis is a disease that crosses gender, age, social and economic barriers. Everyone is potentially at risk for developing osteopenia or osteoporosis. It is imperative that you take the steps necessary to improve your health, exercise, maintain an adequate intake of calcium and vitamin D. The DEXA scan will help you determine your baseline bone density. Medications are available to help slow down bone loss and increase bone mineral density.

Osteoporosis is not a disorder that you should delay in taking the steps to treat. Optimizing your bone density can take time and the earlier you begin, the lower your risk of developing osteoporosis as you age. This will also lower your risk of fractures, complications related to fractures and possibly death.

Important Facts About Bone Health


Osteoporosis, a disease characterized by porous and fragile bones, is a serious problem in the U.S.:

44 million Americans have compromised bone density (osteoporosis or osteopenia).
1 in 2 women and 1 in 4 men over 50 will have an osteoporosis-related fracture in his or her lifetime.
Osteoporosis is responsible for more than 1.5 million fractures annually, costing a total of $14 billion every year.

Conventional wisdom says our bones are made of calcium, so by drinking lots of calcium-fortified milk and taking calcium supplements, we should be able to prevent osteoporosis. Backed by the U.S. dairy industry, America is the only culture that encourages milk drinking way beyond the infant years.

If we are taking in this much calcium in our diet, how come osteoporosis is so prevalent in America?

Are the osteoporosis drugs such as Fosamax, Actonel, Reclast, or Boniva really effective in treating osteoporosis?

What is the real truth about taking calcium for osteoporosis?

Osteoporosis Drugs Don't Fix Osteoporosis

Bone is a dynamic, living tissue that is constantly being reshaped in a complex process of building and remodeling by 2 broad category of cells:

osteoblasts, which build bone, and
osteoclasts, which break down old bone.

As you age, more bone may be broken down than is replaced. The spaces in the honeycomb-like bone gets bigger and the outer shell of your bone gets thinner. All these make your bones weaker.

The biphosphonate drugs for osteoporosis work to kill the osteoclasts and stop the natural process that dissolves bone tissue. That means you are only left with the osteoblasts.

In a way, the drugs do increase your bone density, but unfortunately, not bone strength. Your bones lose their natural ability to build new bones that can adjust to the constantly changing forces applied to them. Yes, you have thicker bones, but with less strength, which actually increases your risk of bone fractures.

In addition, the biphosphonate drugs come with some terrible side effects, including:

thigh bone fractures,
osteonecrosis (damage and death) of the jaw bone,
ulcers,
eye problems,
liver and kidney damage,
atrial fibrillation,
esophageal cancer, and
hypocalcemia (low blood calcium levels).

Therefore, unless your osteoporosis is very severe, a natural approach (read below) is more effective in restoring bone health.

If you want to check your bone density, the most accurate test is the DEXA scan (Dual X-ray Absorptiometry). It measures the bone density of the spine and the hip to gauge fracture risk. Talk to your physician regarding such a test.

Bones Are More Than Just Calcium

For decades, you have been taught to believe that bones are made of calcium. This statement is only partly true. Bones are made of at least a dozen minerals, namely:

calcium,
potassium,
magnesium,
manganese,
silica,
iron,
zinc,
selenium,
boron,
phosphorus,
sulfur,
chromium, and
traces of many other minerals.

Calcium is just one of the minerals in the bone. Although it is very important, it doesn't mean that by taking in a lot of calcium, your bones will be strong. In fact, the opposite is true. If you have an excess of calcium, you can create a grave mineral imbalance in your body.

Any sensible person can see that if you want strong bones, you need to have all of these minerals in your bones and in balance. We deplete our mineral stores on a daily basis, so we need to replace them all every day. Replacing just one mineral creates an imbalance that results in a cascading effect of harm.

Excess calcium draws on more magnesium to keep the body in balance. A relative magnesium to calcium deficiency leads to increased muscle tension, nerve endings firing erratically, and the malfunctioning of other electrical functions of the body.
To retain more magnesium, your body suppresses adrenal function, causing a loss of sodium and potassium in your urine.
This reduces the production of stomach acid, leading to heartburn and other digestive disorders as well as the diminished ability to absorb protein, which results in a deficiency in essential amino acids.
The decline in potassium leads to thyroid hormone resistance and slowed metabolism. The cells become starved for glucose and you have increased sweet cravings.

This goes on and on but the end result of an excess in calcium is multiple metabolic malfunctions:

plaque in arteries, leading to heart disease,
kidney and gall stones.
hypertension,
bone spurs,
obesity,
hypothyroidism,
type 2 diabetes, and
last but not least, osteoporosis.

How do you know if you have excess calcium or mineral deficiency?

The most accurate test is a Hair Tissue Mineral Analysis (HTMA). Blood test only shows what's outside the cells and it can differ greatly from what's inside. By analyzing new hair growth, you get an accurate picture of the mineral profile inside the cells of the entire body. One of the most reputable HTMA labs in the U.S. is Trace Elements Inc. (TEI). Contact me for getting this test.

A Natural Approach To Preventing Osteoporosis

To summarize, osteoporosis is not necessarily a disease of calcium deficiency. It can also be caused by excess calcium and a mineral imbalance in the body.

Food is still the foundation of bone health

Therefore, before you consume large amounts of calcium, either in food or supplement form, get a HTMA test to see if you have any calcium deficiency or mineral imbalance.
Do not use table salt, which has essentially zero nutrition. Use unrefined, unprocessed sea salt instead. Sea salt is 85% sodium chloride and 15% minerals, the exact proportion needed by your body.
Eat as many vegetables (not potatoes) as possible every day and vary the types of vegetables you eat. Minimize the amounts of fruits but maximize the green vegetables, such as kale, spinach, collard greens, broccoli, and brussels sprouts. Try to eat organic or at least local as they are higher in nutritional value.
Vegetable juicing is an easy way to get a proper balance of essential vitamins and minerals for bone health. However, do bear in mind that vegetable juice contains zero fiber.
Vitamin K2 is produced by bacteria in the large intestine. It works to deposit calcium into your bone matrix, instead of becoming calcified in blood vessels and soft tissues or forming bone spurs. Consume fermented foods regularly, such as nato, miso, tempeh, sauerkraut, kim-chee, cheese, and unsweetened yogurt and kefir.
Omega-3 fats is essential for strong, healthy bones. Make sure you get these good fats from wild-caught, cold water fatty fish like wild Alaskan salmon. Eat several times a week.
Eat a nutrient-dense diet by avoiding nutrient-deficient fast foods, processed foods, microwaveable meals, sodas (regular and diet), and sweets.

Prevent Bone Loss With Appropriate Sunshine Exposure

Vitamin D deficiency can result in lower bone mineral density and altered mineral metabolism in the body.
Just 15-20 minutes of sunshine per day can help to maintain your vitamin D levels within the optimal range of 50-70 ng/ml.
The next best option is to take an oral vitamin D3 supplement. Get a blood test and check with your healthcare professional to determine the appropriate supplement dosage.

Exercise To Build Strong Bones

Bone is a living tissue and requires regular physical activity to renew and rebuild itself. Peak bone mass is achieved in adulthood and then it begins a slow decline.
If you are inactive, your bones can become porous, soft, and brittle as you get older.
Weight bearing exercises can combat this effect because when you put more tension on your muscles, you put more pressure on your bones, which then respond by continuously creating fresh, new bone.
Walking, jogging, hiking, dancing, jumping rope, jumping jacks, step aerobics, stair climbing, squats, walking lunges, and weight lifting are examples of good weight bearing exercises.

Stay Away From Cortisone

High-dose cortisone is a common cause of osteoporosis as it interferes with the process of building and remodeling in bones.

Gluten Intolerance Leads To Bone Loss

If you have chronic gas, bloating, diarrhea, constipation, nausea, brain fog, these can be signs of undiagnosed gluten intolerance.
Undiagnosed gluten intolerance can lead to intestinal damage and malabsorption of nutrients, and eventually osteoporosis.
People with gluten intolerance should go on a gluten-free diet.

Progesterone Deficiency Leads To Bone Loss

Pre- and post-menopausal women usually experience declined levels of progesterone, which is a sex hormone that helps to increase bone building.
Consult with your healthcare professional regarding supplementation with bio-identical progesterone.

Remember, osteoporosis is not a malady that merely strikes the elderly. What you do and eat from the teenager years onwards have a tremendous effect on the health of your bones for the rest of your life. So, start early and start soon.
