The study by doctors in Seattle also noted that insulin resistant people with excess abdominal fat also appeared to show higher concentrations of a substance known as apolipoprotein B (apoB) and lower levels of high-density lipoprotein (HDL) cholesterol, a “good” form of cholesterol. Previous studies have suggested that high levels of apoB may encourage the development of arteriosclerosis.

Study author Dr. Steven E. Kahn of the VA Puget Sound Health Care System in Seattle, Washington, states that he and his colleagues suspect that a potbelly likely precedes insulin resistance. Once both conditions have set in, he noted, people’s bodies are more likely to be primed to develop arteriosclerosis.”We think that the deposition of fat in the inside of the abdomen is the critical determinant of insulin resistance in the general population,” Kahn said. “We think that the fat begets the insulin resistance, which helps produce” risk factors for arteriosclerosis, he added.

Kahn’s is not the first study to identify health hazards of potbellies. Although body fat tends to relocate to the abdomen with age, past research has shown that excess belly fat, compared to fat elsewhere on the body, can increase the risk of heart disease and type 2 diabetes, as well as up the chances of stroke in middle age.

In the current study, Kahn and his colleagues measured body fat distribution and screened for insulin resistance in 196 people. The authors also determined how much choesterol, fat, and apoB was present in each participant’s blood.

The average age of study participants was 53. They were all seemingly healthy, with no history of diabetes or cardiovascular disease.

Reporting in the January issue of Diabetes, Kahn and his colleagues discovered that people with bigger potbellies who were more resistant to insulin also had lower levels of HDL cholesterol and higher levels of low-density lipoprotein (LDL) cholesterol–the “bad” form of cholesterol.

Risk factors for arteriosclerosis appeared to be linked more strongly to tummy size than to whether a person had insulin resistance, Kahn and his team note.

The current study findings suggest that even people who are not obese can be at risk of arteriosclerosis, the authors note. Seemingly slim people can carry excess tummy fat and be resistant to insulin, they write, and can therefore be at risk for the blood vessel disease.

In an interview, Kahn noted that abdominal fat could play an essential role in people’s risk of future disease. Specifically, he said having a pot belly “is a critical component of metabolic syndrome,” a condition marked by insulin resistance and high blood pressure, and which often precedes diabetes and cardiovascular disease.

According to recent research, those who have a large potbelly appear to have a higher risk of arteriosclerosis. This is the medical term for the fatty buildup on the lining of arteries that researchers now believe increases the risk of heart attack and stroke. SOURCE: Diabetes 2003;52:172-179

People who carried this “spare tire” of fat around their waists are more likely to have increased fat and cholesterol in their blood.

The study by doctors in Seattle also noted that insulin resistant people with excess abdominal fat also appeared to show higher concentrations of a substance known as apolipoprotein B (apoB) and lower levels of high-density lipoprotein (HDL) cholesterol, a “good” form of cholesterol.

311216 Fat-the good and bad of it

311216 Fat-the good and bad of it

Just what you wanted to know entering the New Year festivities. Sometimes guilt trips work…

A key component in assessing an individual’s health and physical fitness is knowing the body composition makeup. Obesity (excessive body fat relative to body mass index (BMI) of 30 kg/m2 or more) and becoming overweight (Adults with BMI between 25-29.9 kg/m2 or with children being in and over the 95th percentile for their age and sex) is at epidemic proportions in the United States and the trend is gathering momentum.

Right now we are at the top of the fat list compared to the majority of the nations in the world-an unfortunate but sad fact.

Being obese brings serious health consequences and reduces life expectancy by increasing the risk of developing serious diseases such as coronary heart disease, hypertension, aka the silent killer, type 2 diabetes, obstructive pulmonary disease, osteoarthritis and even certain kinds of cancer.

Just as too much fat in the body can cause problems, so can too little. Our body needs fat to operate in a normal physiological fashion. For example, the essential lipids such as the phospholipids are vital to cell membrane formation. The non essential lipids such as triglycerides which are found in the adipose (fat) tissue protect the body by providing a layer of thermal insulation. Fat tissue assists in storing metabolic fuel in the form of free fatty acids.

These same lipids are also involved in the storage and transport of the fat soluble A, D, E, and K vitamins and in helping to maintain the functionality of the nervous system. The menstrual cycle in females and the reproductive systems in both male and female rely on these cells, as does the growth and maturation processes of the pubescence child.

Thus, too little body fat as seen in those with eating disorders such as anorexia nervosa, or someone with an exercise addiction or even certain diseases such as cystic fibrosis can lead to serious physiological health related consequences.

The best option is to be in the normal range for body fat, not over or under the recommendations if you desire to have good health.

Testing the body fat levels

The previous article briefly discussed the near crisis issue of being overweight and the staggering rise of obesity in our nation. Here we are going to look behind the scenes at the testing methods that determine fat or fit.

A classification of the level of body fat relies on the standard relative body fat percentages commonly used across the world. These classifications are in turn then broken up into age, sex, and activity body fat percentages at recommended levels. Across the scale women carry more body fat than males and younger people of both sexes carry less fat than older adults. This is due to the role women have in the reproduction of our species.

What are the body composition measures used for?

Body composition measures are useful in estimating a healthy body weight and figuring out a recommended nutritional plan. Both of these components are essential in designing an exercise program that will be beneficial to the trainee. Athletes who participate in weight bracket sports such as bodybuilding and wrestling need to know their ideal weight in order to be competitive. Pediatricians and other health care professionals make note of these measurements while monitoring the growth of children and to identify those who are at risk of being under or over weight.

The population of our country is getting older and the changes in body composition are important indicators of whether the person is remaining healthy or not. In each case, the assessment of body fat helps to determine the nutritional and exercise prescription intervention strategies that play a prominent role in charting a course of action to improve health and fitness levels.

Background on the measurement procedures

The body is made up of water, protein, minerals and fat substances. Most body fat identification procedures rely upon the two component model which divides the body into two sections: fat free and the fat tissue. The fat free is made up of all the chemicals and the tissues including water, muscle and the bones. The rest is fat. The testing methods separate the water, protein and minerals from the fat and then give a percentage of lean body mass to fat mass. Stay active and healthy in your life.

310816 Eggs are OK now

Eggs are OK now[1]

Eggs are OK now, just as they were 40 years ago.

A new study out of the University of Finland confirms what our Mothers and Fathers told us back then (for those of us who were around back then). This study reports that eating an egg a day doesn’t increase the risk of cardiovascular disease, even in those genetically predisposed to a higher than normal effect of dietary cholesterol on their serum cholesterol levels.

This study is a direct contradiction from what we have been told for the last several decades. In fact, over the past few years, several studies have reclassified eggs back into the good to eat category.

Researchers found no association, in the participants of the Finnish study, among those with the APOE4 phenotype. This particular hereditary phenotype affects cholesterol metabolism and is present in about one third of the Finnish population who are also carriers.

290216 Eating clean

290216 Eating clean

The experts at Tufts University set out the basic principles of eating clean as described in the book Eating Clean for Dummies. These are simple, common sense, guidelines that follow good dietary advice.

Start out with whole foods, preferably right from the farm that produced them. These would include such food items as whole fruits, vegetables, whole grains, and chemical free meat. Included in this area will be low fat dairy products, unsalted nuts (Costco sells these and they are delicious) and many varieties of seeds.

Some people believe that if the food is frozen, it detracts from the nutrients. This is not so, because by neglecting the frozen food isle in the store, you miss the great food choices such as the countless fruits and vegetables available there. Don’t forget the canned beans either. Rinse the liquid off of them first and then have at it in your salads or other dishes.

The most recommended advice from numerous sources is to avoid processed foods. This means any food with a label on it. If you actually do this, you miss out on many healthful options. For example, sugar is processed but so are the other options that are sugar such as agave syrup, fruit concentrate, or honey. The message here is to lower your intake of sugar regardless of its source.

Eating clean means figuring out what are the best options for your eating habits. Some have success grazing all day with five to six small meals during the day. Others stick to a more traditional three meals, with healthy snacks between them. Just make sure the food you eat is more nutrient dense with fewer unhealthy fats, less sugar, and lower sodium contents.

Whether you like to cook or don’t like to cook, the fact of the matter is if you cook your own food, you decide the contents. This can mean less sugar, less fat and less sodium in each meal all of which contribute to a healthier eating style. Plus you may save money too.

The last bit of advice from the experts at Tufts University is to make healthy food choice every day. Choose from the tremendous options of foods in the stores and make certain to get all three categories in your meals. These include the lean proteins found in fish, chicken, and vegetables. Stock up on whole grains of all sorts and use them in your cooking along with high fiber carbs and unsaturated fats[1].

Alter your eating habits one at a time; soon you will notice the benefits of the changes in your health and overall self-confidence.

Monounsaturated fatty acids. This is a type of fat found in a variety of foods and oils. Studies show that eating foods rich in monounsaturated fatty acids improves blood cholesterol levels, which can decrease your risk of heart disease. Research also shows that these fatty acids may benefit insulin levels and blood sugar control, which can be especially helpful if you have type 2 diabetes.

281013 Increased belly fat raises your risk for heart disease and cancer

Increased belly fat raises your risk for heart disease and cancer

A study of 3000 Americans, recently published in the Journal of the American College of Cardiology on 10, July, concluded that those with excess belly fat had a greater risk of developing heart disease and cancer in comparison to those who had excess fat elsewhere on their body. These citizens, average age of fifty, were followed for seven years during the study.

During this time, ninety of them had some sort of a cardiovascular episode, one hundred and forty one were diagnosed with cancer, and there were seventy-one deaths out of the original 3000 participants. It is unknown what caused these deaths.

Belly fat, the fat surrounding the organs in the abdominal cavity, is associated with raising the risk of both heart disease and cancer. The researchers admitted that this study did not show a clear cause-and-effect but there are strong connections.

Belly fat is also often an issue found in those with the metabolic syndrome, which is a grouping of known risk factors for poor health such as unhealthy cholesterol and blood sugar levels and high blood pressure. Each of these puts one in jeopardy of developing cardiovascular disease, diabetes and a strokes.

Changing the diet and getting more exercise each day can have significant influences on these health conditions.

Risk factors that you can control toward keeping your heart healthy

• High blood pressure
• High cholesterol
• High triglycerides
• Diabetes
• Smoking
• Being over weight
• Alcohol consumption
• Excess stress
• Physical inactivity

You can take steps to mitigate each one of these if you have the mind to do so. Some may have to use various forms of medical interventions to help control their high blood pressure, high cholesterol, high triglycerides, and diabetes. But the remainder, smoking, being overweight, alcohol consumption, excess stress and physical inactivity are squarely within your ability to change.

231013 An introduction into strength and power training for all ages

An introduction into strength and power training for all ages

It turns out there are effective actions you can do to positively alter your health. They can help improve your blood sugar and cholesterol levels, help improve your mood, make you stronger and more powerful, and at the same time make your bones stronger to help ward off fractures. These are not the only benefits these actions, not by a long shot.

They can potentially help you avoid disability, frailty and retain that precious independence we all want to have as we age.

Strength training can do all of this.

It is a well-known fact that strength training offers all of the benefits previously mentioned, in addition to many others such as are listed in the following section from the Harvard Medical School.

“Practically any regular exercise benefits your health. Strength training specifically helps in the following ways:

• Strengthens muscles
• Strengthens bones
• Prevents falls and fractures by improving balance and preserving power to correct missteps
• Helps to control blood sugar
• Relieves some of the load carried by the heart
• Improves cholesterol levels
• Improves the body’s ability to pluck oxygen and nutrients from the blood stream
• Boosts metabolism even while sleeping and thus helps keep weight within a healthy range
• Prevents or eases lower back pain
• Relieves arthritis pain and expands limited range of motion
• Raises confidence , brightens mood, and helps fight mild to moderate depression
• Wards off loss of independence by keeping muscles strong enough for routine tasks”

According to the Center for Disease Control (CDC) there is now a heightened awareness of the benefits of strength training. There is also the fact that only a small percentage of the American population have actually started a strength training program. This percentage is estimated at just slightly under 22% for men and 18% of the women in our nation who are strength training twice a week on a regular basis.

This percentage figure is far below the U.S. governments Healthy People 2010 goal of 30% of the adults in America who make strength training a part of their exercise program.
