020118 Boosting your insulin response with increased lean muscle mass

020118 Boosting your insulin response with increased lean muscle mass

A brief snapshot of Insulin resistance and why it is important to avoid.

This condition causes the body’s muscles, fat and liver cells to improperly respond to insulin. The pancreas makes the hormone, insulin. This hormone helps the cells take in and use glucose which in turn is a fuel used by the body to function. If there is not enough circulating insulin, excess glucose builds up in the bloodstream and increases the potential for developing diabetes. It is in everyone’s best interest to have as much lean muscle mass as possible to possibly avoid this serious medical condition, especially as you get older.

One of the unwelcome conditions of aging is muscular frailty, also known as sarcopenia[1]. Without strong muscles, coordination and balance problems begin to appear. These problems may be held at bay by greater lean muscle mass. A new study reports that increasing skeletal muscle mass by as little as 10%, is also associated with an 11% reduction in the body’s resistance to insulin and a 12% lower risk of developing transitional, prediabetes or diabetes.

Researchers from the University of California Los Angeles look at the data and 13,644 participants in the National Health and Nutrition Examination Survey (NHANES). Since these people were involved in the study between years of 1988 to 1994, the research is somewhat old. However when the muscle mass of one quarter of the participants was compared between those with the most muscle mass and those at the bottom with the least muscle mass, those with the greatest amount of fat three muscle mass were 63% less liable to get diabetes.

After making adjustments to leave out those with diabetes, the connection between muscle mass and improved insulin resistance became even stronger. According to the study[2], “increases in muscle mass above even average levels were associated with additional protection against insulin resistance and prediabetes.”

Not only is increasing your lean muscle mass important, but also losing weight helps to improve your metabolic health. Most of us already know that the fitter you are, the healthier you are probably going to be.

121217 Balance out your exercise program

121217 Balance out your exercise program

It is well established that exercise benefits us in many areas such as increased self confidence, improvements in our moods, and longer healthier lives. Simply being able to do what you want to do physically and mentally may be made easier by engaging in a long term pattern of running, weight training, stretching/balance, and recreational sporting exertions.

During spring time the runners start hitting the road, especially those who are getting ready to run Bloomsday here in Spokane, Washington. While running is an admirable endeavor, it is not enough to keep your body in top physical condition. Our body needs physical and mental stimulation which is only achievable through the use of a variety of methods.

Cyclic exercise, similar to running, stresses the cardiovascular abilities thereby increasing the capacity to engage in lengthy activities through enhanced oxygen transfer to the working muscles. However, exercising in this manner will not increase the lean muscle mass composition of our body. In order to do that resistance training is necessary.

Weight training helps build strong bones.

Bone density responds directly to increases in intensities of load and site specifically to the greater pressures required to move the load. Adaptations take place within the structures of the bone that make it more resistant to the imposed loads and thus stronger.

Women in particular need this load bearing weight on their long bones, the spine and hips to stave off and help prevent osteopenia and osteoporosis from occurring. Osteoporosis is a degenerative disease that progressively decreases the bone density which in time leaves them weakened and vulnerable to fracture.

 

It is well established that exercise benefits us in many areas such as increased self confidence, improvements in our moods, and longer healthier lives. Simply being able to do what you want to do physically and mentally may be made easier by engaging in a long term pattern of running, weight training, stretching/balance, and recreational sporting exertions.

Flexibility

Getting stronger helps in other ways too. The strength to recover from a slip may prevent a bone damaging fall. Postural muscles that are strengthened through weight training inevitably lead to improved posture and a reduced potential of lower back problems. Even though strength training is high on the list of maintaining a strong fit body other pieces of the equation are important too. For instance being flexible enough to tie your shoes or even scratch your back is an important part of living a full and healthy lifestyle.

Work the joints normal range of motion each day by following a stretching program. But be cautioned that static stretching performed before a strength training session has been found to lower the power output by as much as 8%. If you are a sprinter, thrower or recreational handball or tennis player stay away from these at the start of your activity. The proper place for a static stretch is at the end of the workout when the muscles are warm and receptive to change. Doing so before hand, is an invitation to injury.

Find a good stretching book; read up on the proper way to stretch and start applying these to your exercise program. Brad Walker’s Stretching Handbook or Bob Andersons Stretching are two of the premier ones on the market and each one has stood the test of time. Even though flexibility is important it is not the end of the line. Maintaining your balance becomes harder as we age.

Balance

Prevention begins with daily practice. Standing on one foot or with heel to toe for multiple seconds at a time (60-120) will help stave off this decline in balance. Leaning toward the floor on one leg with arms to the side or rear will change the center of gravity and will change the feel of the exercise. In each instance it is important to have the ability to catch yourself on something solid to prevent a dangerous fall from happening in the event you do lose your balance while doing these.

Of course there are many other ways to practice balance training but this article is not being written to list them all. Suffice it to say balance is a critical part of living a healthy life.

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.

211117 Avoid Breakfast Mistakes

You likely know breakfast is the most important meal of the day. Your athletes need fuel to perform in the classroom and in their sport. Encourage your athletes to eat breakfast but to avoid commons mistakes .

Not Enough Protein – A bowl of cereal with low fat milk is good, but most people don’t drink all the milk that goes with the cereal and that amounts to eight grams of protein! A hard boiled egg, 100% whole grain toast w/ peanut or almond butter gives extra protein.

Too Little Fiber – Avoid sugary breakfast cereal options! Cereal should have at least FIVE grams of fiber, and always more fiber than sugar.

No Fat – A breakfast with no fat will make you hungry within an hour. Cereal, berries and low fat milk delivers the fat you need.

Too Late in the Day – Eat breakfast within an hour of waking

Not Enough Food – Fruit is good but not enough food for breakfast Your athletes should consume 300-400 calories.

141117 Are the bear claws you are eating making you as grouchy as a bear?

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.

More next week.

101017 Americans are severely obese, to the tune of 15.5 million citizens.

101017 Americans are severely obese, to the tune of 15.5 million citizens.

A survey of 3 million Americans, conducted by the RAND Corporation in conjunction with the Center for Disease Control and Prevention, and subsequently published online in the International Journal Of Obesity found that more than 6.6% of adult Americans are now 100 or more pounds overweight! This is an increase of almost 4% (3.9%) from the year 2000.

The cost of healthcare is more than doubling with the epidemic of severe obesity in our nation. Obesity increases the frequency cancer, heart disease, type II diabetes and other chronic and mostly preventable diseases.

When will this stop?

050917 More benefits of exercise

050917 More benefits of exercise

Exercise has been cited as being beneficial for avoiding, lessening, and mitigating a vast array of diseases in the past. Now, new research is confirming even more of these exercise related benefits for those who choose to follow this path to better health.

According to a recent report from Duke University, working out directly affects your heart. You may reduce your risk of developing heart disease up to 25% by doing 750 minutes of high intense minutes each week. By doing 300 minutes of intense exercise you lower your risk of heart disease by 20% and exercising 150 minutes per week lowers the risk by 14%.

Despite scientific research and the medical expert’s advising exercise to manage the pain of arthritis, up to 90% of those with arthritis fail to meet even the standards of 150 minutes of exercise per week. Of this 90%, nearly half get no exercise at all. They are inactive.

Boost your memory with movement.

Aerobic exercise pushes the rate of circulation up and this helps to increase the flow of oxygen rich blood into your brain. A study of almost 300 older people found that of those who walked at least 72 blocks, about 4 miles and 880.0 yards, each week had more gray matter in their brain than those who did not walk or exercise each week. Those who were walking each day cut their risk in half of developing memory problems.

Achieve a calmer state of mind with exercise

Regular aerobic exercise tends to reduce an individual’s level of stress hormones, and decreases the amount of fluctuations in heart rate and blood pressure when under duress. Some of the recommended ways of aerobically exercising are walking, running, swimming, biking, or any other activity that keeps your heart rate up and within the target range for up to 20-30 minutes a day.

Equally effective is resistance circuit training. This method involves doing a series of exercises without stopping for 3-6 times around a circuit-thus the name circuit training. It is most effective with the large muscle groups such as legs, chest, and back. As an example, when doing an intense lower body circuit, the series could look like this: do each exercise for 1 minute. Do this 3-6 times, if you are able.

  • Skip rope
    • Squats
    • Skip rope
    • Calve raises
    • Skip rope
    • Dead lifts
    • Skip rope

Obviously, before beginning any of these exercise suggestions consult with your doctor.
