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.

291016 Reasons to exercise

291016 Reasons to exercise

The benefits of regular exercise are well known in today’s society. It has been consistently demonstrated that it leads to a healthier more productive life. Being active lowers your risk of developing heart disease, adult on set diabetes, sometimes referred to as type 2 diabetes, and osteoporosis. It’s not only these benefits that result from exercise, others fall into place as well.

Those who are regular participants in moderate to vigorous activities have the ability to deal with the stresses of daily life and are less likely than non-exercisers to suffer from anxiety and depression. Longevity has a direct correlation to being active. The more active you are throughout your life the greater your chances of staying healthy and living a longer life.

Following a plan of regular exercise and eating healthy foods and fluids can lower the actuary[1] predictors of coronary heart disease and stroke. Exercising regularly often times means your critical health numbers will become lower. These numbers include your blood pressure, body weight, fat composition, blood triglyceride levels, and low-density lipoproteins (LDH).

The numbers indicating good cholesterol (HDL) rise with good exercise and a healthy diet.

Blood sugar tolerance, also known as glucose tolerance, is the ability of your body to regulate the level of sugar circulating in the blood. When this tolerance becomes lower, the amount of sugar in your blood becomes higher, which may lead to diabetes. Currently, about one in four older adults are at risk of developing type-2 diabetes in the US. The studies are clear in their findings: physically active people are less likely to develop this disease then those who are sedentary. Exercise improves the ability of the body to use insulin, which is a hormone that regulates the amount of sugar in the blood. This process maintains the blood sugar at the recommended levels.

The benefits of exercise far outweigh the time spent working out. Just of few of the reasons to exercise, include stronger bones and better mental health.

Improved bone density

Osteoporosis, a disease where the bones become fragile and fracture easily, is of concern to many older adults. This affects more women than men even though men still suffer from the disease.

Once osteoporosis has progressed to a dangerous level, even a small slip and fall can cause a broken bone, especially in the hips and wrists of a female.

Weight bearing exercise has been well documented in both medical and scientific literature to be of value in strengthening the skeletal bones. Strength training and impact exercises have a direct positive relationship to building stronger bones, particularly the long bones in the body. These types of exercises can help prevent further skeletal bone loss in those with osteoporosis.

Mental well-being is enhanced when you exercise. The release of natural chemicals into your body helps improve your outlook on life. They make the minor momentary pain of exercise feel good all day long. That’s not all there is to the role of activity and exercise in making your life batter. An added outcome of regular exercise is the ability to control your weight.

Less body weight means less stress and trauma on your lower torso joints, i.e. the hips, knees and ankles. It makes sense that the more you weigh the more these joints have to work to stay healthy. Too much bodyweight can damage the cartilage, which in turn fosters the onset of arthritis and osteoarthritis and leads to joint implants.

Remember you will never exercise your way to more lean muscle mass through a high calorie diet. Eating or drinking too many calories will not be exercised away, contrary to what the machines are telling you about the caloric expenditure for X-amount of time on them.

220816 Healthy movement

Healthy movement is beneficial to your body and at its lowest level, even some activity is better than doing nothing. If you are just starting out then gradually build up your endurance with 5 to 10 minute exercise breaks throughout the day. At the 10-minute level, your body begins to adapt and then noticeable changes become evident.

After you are able to exercise aerobically for at least 10 minutes, it is time to branch out by adding resistance exercises to the daily routine. One way to begin is by doing one 10-minute session of endurance work and then later on in the day doing 10-minutes of resistance training.

Alternate between aerobic and resistance training for at least thirty minutes for the day.

The aerobic exercises can be brisk walking, skipping rope, riding a bike or any other activity that is continuous and places a demand on your breathing and heart rate. After you are finished then cool down with static stretches, holding each one for fifteen to thirty seconds. Do this three to five times for each stretch.

For the resistance training start out with body weight calisthenics by doing 3-5 sets of fifteen to thirty bodyweight squats, push ups, calf raises, prone back extensions, curl ups, leg raises or others of your choosing. You can do these in a circuit or one exercise at a time. Stay with it for the full 10 minutes.

If you are over sixty-five, the health benefits of activity are just as important to you as they are to the younger people. Start slowly and build up your fitness levels over time. If you have chronic health problems, work around them and do what you can.

If you aren’t able to ride a bike or have access to a treadmill or other such equipment, then get one of the hand ergometers available at Costco for about $49.00 and exercise your upper body. Do counter top pushups by standing two or three feet away from a counter top and then doing pushups on it.

Do chair sits. Sit in and stand up from a chair without pushing on your legs with your hands as you stand up. Practice sitting down on a chair; standing up, walking away briskly for 10 feet, and then coming back and sitting in the chair again. Repeat this for a minute or more. This builds up leg strength and helps with your balance.

Practice your balance to help prevent falls by walking sideways, standing heel to toe; practicing the stork stand on one leg with the other bent ninety degrees at the hip and knee or any of the many other balancing exercises.

310713 Timing your meals to increase the effectiveness of your workouts

 Timing your meals to increase the effectiveness of your workouts

Morning workouts may be somewhat better for weight loss. There is some evidence showing that more fat is burned when exercising before eating breakfast. This may be because when exercising later on these sessions will be fueled by the proteins and carbohydrates from meals eaten earlier in the day.

However, if you have any type of a heart disease, working out in the morning may not be your best option because your risk of a heart attack is slightly elevated.

Some of the research is showing that exercise in the afternoon may be better for building strength and endurance. These same studies are showing that your aerobic capacity, coordination, flexibility, muscle strength, and reaction time show the greatest training peak between 1600 and 1900 hrs.

Even though the research is becoming clearer as to the best time to exercise each day, it is not going to make a hill of beans if these times are not good for you.

Each day is special, and each day you have to make a conscious decision as to when you are going to work out. The more habitual this workout time becomes the better the chances are that you are going to stick with it over the long haul.

As for deciding what time to eat your biggest meal of the day, you may want to keep this in mind: stuffing yourself at the local buffet shortly before going to bed will almost guarantee you of a poor night’s sleep because your body is working to digest all the food you ate.

050713 Americans are severely obese, to the tune of 15.5 million citizens.

 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?

The health benefits of water to your brain

If you want to do something to help your brain the most, drink water. Since the brain is 80% water, dehydration leads to increases in the stress hormones, which in turn interfere with cognitive abilities. When referring to liquids that hydrate the body, we are excluding coffee or alcohol.

According to Medical Dr. Daniel G. Amen and Tana Amen, RN., you should be drinking half your weight in water ounces every day. For example, a person who weighs 200 pounds should be drinking 100 ounces of hydrating liquids over the course of their waking day. Naturally, you should be drinking more water when the day is warm and humid or if you are working outside or exercising and losing water to perspiration.

Keep hydrated for peak mental and physical performance.

“The starting point of all achievement is desire. Keep this constantly in mind. Weak desires bring weak results, just as a small fire makes a small amount of heat.” — Napoleon Hill, author

Many people equate physical fitness with being able to run long distances or ride the cardio machines for a long time without stopping. Certainly those are admirable goals but jogging or using these machines for long slow workouts does very little to increase your fat loss. One proven way to lose fat is to increase the intensity. You can do that by doing hard, fast, intense intervals.

Interval workouts consist of specific, high-intensity, time limited exercises and using 20 to 90 seconds of rest in between each high-intensity section.

For example, if running outside, you would warm up with an easy 5-minute run. Once warmed up, you would transition into 5 to 10 high-speed sprints. Each of these high intensity sprints would last between 20 to 30 seconds at approximately 80 and 90% of your fastest speed. Keep in mind that if you continuously try to go one hundred percent of your fastest speed, eventually you will create a speed barrier, which is another topic altogether and will not be further discussed. Suffice it to say these self-inflicted physical and mental barriers are hard to break.

By continually challenging yourself and lowering the rest periods between the intervals you increase the intensity, which increases the benefits, which burns more calories. It sure sounds simple doesn’t it?

Anyone trying to lose weight knows it’s not as easy as this to do. Cardiovascular exercise is not the only ticket to increasing weight loss nor is it the only ticket to staying physically fit. Well-structured weight-loss programs utilize strength training to boost metabolism (1) and increase lean muscle mass.

(1) Metabolism–noun 1. Biology, Physiology. The sum of the physical and chemical processes in an organism by which its material substance is produced, maintained, and destroyed.

100613 Using exercise to lose and maintain your weight

Using exercise to lose and maintain your weight

“Create a definite plan for carrying out your desire, and begin at once, whether you’re ready or not, to put it into action.” — Napoleon Hill, motivational expert

Losing weight, in the simplest of terms, means using up more calories than you take in. According to the scientific research, one pound of fat is 3500 calories. Therefore, in order to lose one pound of fat you either have to burn up 3500 calories or cut 3500 calories from your diet. Obviously not eating 3500 calories from your diet in one day is not going to cut it.

Maintaining your ideal weight is a matter of balancing the number of calories required to remain there. This means balancing out the number of calories consumed with the calories burned during the day. The United States Department of Agriculture’s site at ChooseMyPlate.gov states that 60 minutes of moderate to intense exercise is needed each day to prevent an increase of body weight or to lose weight.

If you have already lost the weight and want to keep it off, then maintain your caloric intake and physical activities at the current level and you should be OK. But pay attention to the scale and don’t let it creep back up again.

The key ingredient to losing or maintaining weight is to have an exercise plan.

Throughout the week, schedule time to do cardiovascular work, strength training, and stretching exercises. You could do each of these in each session but doing so would mean giving short shrift to one or more of them. You may be better off scheduling separate times for each.

For instance, one week’s schedule could look similar to this: three days of cardio and two days of strength training with stretching include at the end of each. The next week would be three days of strength training, with two days of cardio with stretching at the end. The reason you do the majority of stretching at the end is because your muscles are warmed up and your body is in a much more receptive mood.

100313 Weight gain and lack of sleep

Is your weight gain caused by a lack of sleep?

The lack of sleep and its relationship to gaining weight has been the subject of a great deal of research in recent years. In a study published in the American Journal of clinical nutrition, researchers believe they have found an explanation to this question. They used MRI scans on individuals who slept four hours a night for six nights in a row.

After completing the MRI, these people were shown pictures of food. During the viewing, the areas of the brain that responded to pleasurable activities increase to a greater degree than when they slept nine hours.

The scientists believe that this increased brain activity leads to a high potential of overeating.

Other researchers discovered that a lack of sleep might cause weight gain because it affects the appetite hormones within the body.

Weight gain and your health

Eating less protein increases your chances to gain weight

Researchers at the University of Sydney, Australia and Massey University in Auckland, New Zealand believe that a low-protein diet causes people to add weight. They compared individuals whose daily diets consisted of 10% and less protein with those who daily consumed 15% and above protein over a four-day period.

Those who were eating only 10% protein averaged 1000 more calories over the four-days of the study. Granted this is a short-term glance at the connection between low-protein and weight gain but it still shows a link.

The possible reason for the weight gain in the minimal protein group could be this group may have not felt as full as those eating more protein did.

Weight gain and prostate cancer

In a study of 2,498 men conducted by the Bloomberg School of Public Health, Johns Hopkins University, Baltimore it was found that prostate cancer survivors have a higher risk for recurrence if they gain weight.

After looking at the data compiled from the study, it was found that gaining five or more pounds five years before the surgery and one year afterwards had a decidedly negative effect on the individual’s health. The results indicated those who had gained the weight were twice as likely to experience a recurrence of the disease when compared with those who maintained or lost their weight.

Reducing your hospital stay by walking

An article recently published in the Archives Of Internal Medicine stated that people who walk the most in the hospital after surgery leave earlier. This study looked at 485 people who were 70 years and older.

They found that patients who were able to walk and walked around their rooms or the hospital wards at least once a day decreased their hospital stays an average of one day. These patients were compared with those who stayed in their beds or remained seated instead of walking around.

Those patients who walked around the same day of the surgery spent even less time in the hospital.

The message here is to get moving, yes it may hurt, nevertheless, when the doctors are encouraging you to be mobile and you don’t take advantage of this then you’re going to spend more time in the hospital.

appq� T��� x�� lems 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.
