171218 Obesity 2/2

Obesity poses a serious threat to our health and occurs when the overall amount of calories consumed exceeds the calories expended. Per the accepted definition, obesity is an excessively high proportion of body fat in relation to lean body mass on an individual.

If your child is between two and five years old and they are overweight or worse yet, obese, there is sufficient reason to be taking additional health related to steps to reduce their body fat.

Consult with your pediatrician and work together to stabilize and then reduce the level of body fat in your child. The suggestions may include a healthier diet with an ample selection of fruits, grains, milk, vegetables, and non-sugary fruit drinks along with exercise or physical activity.

You can start by going to the USDA MyPyramid site here at http://teamnutrition.usda.gov/resources/mpk_close.pdf to see for yourself what a healthy diet consists of for your child.

Help your child grow healthy and live a life that is not consumed by potentially avoidable medical problems.

Obesity, as stated earlier, poses a serious threat to our health and occurs when the overall amount of calories consumed exceeds the calories expended.

Obesity, per the accepted definition, is an excessively high proportion of body fat in relation to lean body mass on an individual. Another common indicator of obesity is a mathematical chart comparison of weight with height. These graphs use a standard of acceptable or desirable weight when compared to the height of the person measured.

The body mass index is one of the most frequently used measures to determine a healthy weight. The Centers for Disease Control and Prevention uses a mathematical formula. These calculations divide the person’s weight in pounds by the square of the person’s height in inches. The answer is then multiplied by 703.

There are also formulas that use the metric system.

However, this formula does not take into account the lean muscle mass on the person, so if one is heavily muscled the BMI will inaccurate.

When children are born, they have extra fat. This helps them make an easier transition from the womb into the outside world. As they approach five years of age both body fat and body weight are at the lowest points of their lives.

Breakfast
Not long ago I was asked to review the science on the benefits of breakfast for a cereal company. Although it is a common truism that “breakfast is good for you” I wanted to know if it remains good advice. So I plunged into 30+ research papers to see what was agreed about the first meal of the day. Here is what I learned.

A large Australian study from last year showed that breakfast was critical for school performance, boosting both literacy and numeracy skills, independent of the socio-economic group. This backed up a review of the previous 50 years of studies in school children. There is no doubt that breakfast is necessary to help you to learn new stuff. Usually not difficult with primary school kids because they wake up hungry. It is the upper high school kids we need to convince.

Breakfast habits changing
Twenty years ago just about every young kid ate breakfast, with only some older teenagers giving it a miss, rising to 15% of 19-24 year olds being breakfast skippers. Now we have nearly 1 in 4 of upper high school students missing breakfast, in Australia at least.

Two decades ago, over three quarters of adults ate breakfast. Now barely 6 out of 10 adults regularly eat breakfast, women being better than the menfolk. Why the decline? The most common excuse is “not enough time”, in other words not enough time to pour out cereal into a bowl, add milk and consume (Gee, that’s gotta take 6 whole minutes) or plonk two slices of bread into the toaster, shave/brush hair/pack lunch while you wait, then add peanut butter. Let’s see, that’s 7.5 minutes.

But then my concept of time and food differs to most people, a fact I accept and have resigned myself to, especially since the day I saw a line of cars outside the drive-thru section of a famous takeaway at 8 am on a school day.

What if you don’t fancy breakfast?
Don’t know how you can do it, frankly. Me? I can’t do without breakfast. No breakfast and I can’t do up shirt buttons, I squeeze Heel Balm onto my toothbrush and drive into oncoming traffic. I have a court order to eat breakfast by 7.30 am or face serving jail time.

You, of course, may be able to get away with it. Can I suggest that you at least have a banana, a yogurt or one of those breakfast drinks as you leave the house? With some glucose racing through your arteries you will make better decisions. Then, when you do feel hungry, eat smart, like choose a sandwich, fruit or a smoothie and not scarf some eye-level, salty, extruded snack from the vending machine. Just the term “extruded snack” should put you off.

What does it all mean?
It means what it has always meaned. Clever people eat breakfast and breakfast eating makes you clever. The evidence is pretty over-whelming.

There are plenty of choices to kick-start the day – breakfast cereals or muesli with milk, topped with nuts or a banana (my choice), wholegrain toast with peanut butter, poached eggs and mushrooms on toast, yogurt and canned fruit and you can think of more. If you buy your breakfast look beyond the cappuccino and croissant because you are worth a lot more than that. A lot more.

Breakfast
Not long ago I was asked to review the science on the benefits of breakfast for a cereal company. Although it is a common truism that “breakfast is good for you” I wanted to know if it remains good advice. So I plunged into 30+ research papers to see what was agreed about the first meal of the day. Here is what I learned.

Leaner
Breakfast eaters are less likely to be chubby. And it doesn’t matter if you are at primary school, university or calling the shots from head office. That might be all you need to know to reach for the cereal bowl. So, why are breakfasters likely to be leaner? You can probably take a good logical guess at that yourself.

Breakfast eaters are more likely to be active and eat a decent diet for the rest of the day. No surprise there. If you are fit, you get more hungry and can’t bypass breakfast. It may also be that eating soon after arising helps regulate your appetite control hormones, normalise your blood glucose levels and improve insulin sensitivity. There is some evidence that a long fast leads to higher levels of ghrelin, a hormone that may stimulate hunger and overeating.

Lifelong benefits
Breakfast doesn’t just pay dividends in the morning; it seems to give a good return on investment at the back end of life too. Breakfast skippers have a higher total cholesterol, higher LDL cholesterol (the evil one), an extra 5 cm (2 inches) of belt leather needed and, in one US study, a 21% greater risk of type 2 diabetes.

Smarter
It seems that with breakfast, you are more likely to meet your nutrient needs for the day. This may be because most breakfast choices are nutritious. Many breakfast cereals are fortified with nutrients like iron and folate. Milk or yogurt adds calcium and riboflavin. Add fruit or nuts and there is vitamin C, potassium, fibre, and on it goes. Miss breakfast and those two biscuits with coffee at morning tea don’t exactly make up the loss.

Researchers at the University of California in San Diego have found a potential link between trans fat consumption and its effects on our behavior.

They found that the fats commonly used in commercial baking and frying operations can make people both aggressive and irritable. Not only are trans fats linked to increased heart disease, they also hinder the ability of omega-3 fats in reducing aggression and irritability our bodies.

Because of this link between the omega 3 fats, aggression and irritability, the researchers felt that eating more trans fats would tend to boost these types of negative behaviors.

Not being content with just feeling this was going to happen, they tested a small group of 945 adults by examining their diets and comparing the diets with a behavioral assessment tool. This group of adults self-reported any feelings of impatience, irritability along with a history of aggression.

The conclusion of the scientists was that the greater the intake of trans fats in these 945 adults, the greater was their aggression and irritability when closely examined against the measures of the behavioral assessment tool.

This was also a significant association when compared with other known aggressive predictive tools frequently used as testing devices.

Another study, conducted at the University of North Carolina, compared the amount of trans fatty acids in the diet and the occurrences of a stroke amongst 87,025 post-menopausal women between the ages of 50 to 79.

They found that those who were eating an average of 6.1 grams a day had a whopping 39% greater risk of having a stroke than those who ate 2.2 grams per day.

It makes sense to look at the labels on the food and eliminate trans fats from your diet. This may be difficult if you like commercially made baked goods from the grocery store or donut shops such as the bear claws and other delights. Moreover, the French fries may contain an unhealthy amount of trans fats. Sometimes life just isn’t fair is it?

The problem

Nearly every newspaper or magazine on the stands has an article about the obesity problem in today’s modern society. In case you are not aware of the dangers of being overweight here are just a few of the conditions that can have a major impact on your quality of life and on your lifespan. Obesity increases your chance of developing heart disease, hypertension, type two diabetes, cancer, arthritis, asthma, and sleep disorders.

The how much 

A body mass indicator (BMI) is not the same as a body fat indicator. The BMI indicates weight compared to height and is not valid for most athletes or those who are above average in muscle density. The BMI will give guidelines to a person who is underweight, normal, overweight or obese. Being overweight is asking for trouble down the line so this must be controlled before your health begins to fail.

The common formula for BMI determination (in inches and pounds) is
BMI= (current weight expressed in pounds ÷ height expressed in inches X height in inches) X 703.

For example, a male weighing 215 pounds and standing 5’11” would use the equation numbers of BMI= (215 ÷ 71 X 71) X 703 = 29.98

The BMI gives a good indication of the amount of body fat on your body. This relationship varies depending on your age and gender. Most women will carry a higher percentage of body fat than most men will for the same BMI score. As we age, the muscle tends to atrophy due in part to a lack of use, which causes excess body fat accumulation. This does not mean if you stop exercising ‘the muscle turns to fat’ as physiologically this is an impossibility for two distinct cells to morph into different cells i.e. a muscle cell will not turn into a fat cell.

The solution

So what do you do about this turn of events in your life? The short answer is to begin to exercise, but only after speaking to your doctor about your plans. Second, find ways to reduce the stress in your life. Next, a gentle but structured exercise program is the safest way to losing your stomach fat.

If you are short of time and cannot go to the gym for a full session then do three to four ten-minute bursts of cardio throughout your waking hours on your aerobic day. On alternate days of the week do eight to ten different resistance exercises. These too can be split into shorter periods of activity spread over the course of your day.

Two days of resistance training and two days of cardio will be a good starting point towards better health. Gradually build up the intensity of your exercise sessions because intensity burns fat, not gently jogging or lifting light weights for a few sets. Get your heart rate up, breathe heavy and hard (within your target zone of course), and push the muscles into areas they have not seen in a while. In short, put something into it in order to get something out of it-like the fat in your stomach!

Try this routine out for a month and see how much better you feel at the end of thirty days.

On the cardio days do some walking, ride your bike, or even some light jogging. Remember, that when you first begin you do not have to keep up with every hot shot in the gym or on the running course. If you forget to gradually work up to it, your body will remind you of the folly of your actions the next afternoon.

The problem

Nearly every newspaper or magazine on the stands has an article about the obesity problem in today’s modern society. In case you are not aware of the dangers of being overweight here are just a few of the conditions that can have a major impact on your quality of life and on your lifespan. Obesity increases your chance of developing heart disease, hypertension, type two diabetes, cancer, arthritis, asthma, and sleep disorders.

The why

Recent research has found that stress actually changes your nervous and hormonal systems around so they encourage fat accumulation around the waist. This type of fat is dangerous and can lead to an increase in your chances of developing hypertension, heart disease and diabetes.

The October issue of Obesity Research featured a report by Swedish scientists, which found changes occurred in the hypothalamic-pituitary-adrenal connections.  This intricate system regulates the part of the brain that controls metabolism through the adrenal gland. They also found that men with accumulations of fat in the stomach had nervous system changes that help to keep the bodily functions in balance. These researchers believe that these brain and neuroendocrine changes happen due to a life of chronic stress.

The how

One method of determining where you store your body fat is to use the waist to hip ratio formula. Take a measuring tape from your sewing room or sewing kit and measure the circumference of your hips at the widest part of your buttocks. Write this number down and then measure at the smallest circumference of your waist, just above your navel. As you measure your waist, don’t suck your stomach in, as this will give a false reading. Letting it all hang out is the best stance here.

Divide the hip number into the waist number to determine the ratio. If the number is one or above you are at an increased risk of one or more of the diseases previously listed.

The formula is Waist ÷Hip and anything less than one is good news.

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.

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.
