Obesity and Sedentary Life Style Can Affect Your Prostate and Your Outcomes of Treatment

January 24, 2014

Obese men are more likely to develop aggressive prostate cancer and are more likely to die of their disease. Researchers at Johns Hopkins may have uncovered the explanation. Obese men have shorter telomeres. Telomeres are like aglets on shoelaces or the little tips that protect the ends of their chromosomes. Short telomeres can cause the chromosomes to become unstable and this abnormality is strongly associated with cancer. Their research in collaboration with doctors at Harvard Medical School found that men with shorter telomeres had a much higher risk of dying from prostate cancer.

Not only did obesity demonstrate shorter telomeres and who were physically inactive had even shorter telomeres compared to men of normal weight and who were the most physically active.

Bottom Line: Telomere shortening in prostate cells is associated with obesity and decreased physical activity. Therefore, this is one more reason for men to adopt a healthy lifestyle and develop good nutritional habits and get moving!

The New Equation: Stress = Excessive Eating = Obesity

May 25, 2012

Stress can impact your eating habits and lead to obesity, the national epidemic affecting millions of Americans. Doctors have now unraveled the relationship between stress and obesity. With chronic stress, the hypothalamus, located in the brain and where stress starts, sends a signal to the pituitary gland to release ACTH or adrenocorticotrophic hormone, which travels via the blood stream to the adrenal gland and stimulates the release of cortisol. Chronic stress leads to far more cortisol than is necessary which in turn stimulates the appetite as the cortisol secretion is turned on and off with excess stress resulting in excess ACTH to fuel the reaction. Cortisol has now been shown to activate lipoprotein lipase, the enzyme that facilitates the deposition of fat. Finally chronic stress is associated with increase anxiety, apathy, and depression, which by themselves may lead to excessive eating and obesity.

That’s the bad news. The good news is that exercise can help relieve chronic stress, reduce your appetite, and promote weight loss. Physical activity can protect against feelings of distress, defend against symptoms of anxiety, guard against depressive symptoms and the development of major depressive disorder and enhance psychological well-being.

Studies have documented that 30 minutes of exercise a day appear to have stress-reducing benefits. The type of exercise does not seem to make a difference. However, the intensity of the exercise does have an impact on stress reduction. The research shows that moderate to vigorous physical activity reduces stress better than low-intensity activity.

Bottom Line: Stress can be a killer just like heart disease. Want to make yourself heart healthy? Then reduce your stress by exercising. Your heart and so many other organ systems in your body will thank you.

Low Testosterone Affects More Than Your Libido

March 30, 2012

It has been accepted that testosterone is responsible for a man’s libido or sex drive. However, we have now discovered that testosterone is responsible for far more than a man’s libido.
Diabetes, metabolic syndrome, obesity, and high blood pressure have all been linked to testosterone deficiency. Low testosterone isn’t known to cause these health problems, and replacing testosterone isn’t the cure. Still, the associations between low testosterone and other medical conditions are interesting and worth a look.
Does Low Testosterone Indicate Poor Health?
In recent years, researchers have noticed general links between low testosterone and other medical conditions including obesity, diabetes, and hypertension.
Diabetes and Low Testosterone
A link between diabetes and low testosterone is well established. Men with diabetes are more likely to have low testosterone. And men with low testosterone are more likely to later develop diabetes. Short-term studies show testosterone replacement may improve blood sugar levels and obesity in men with low testosterone.
Obesity and Low Testosterone
Obesity and low testosterone are tightly linked. Obese men are more likely to have low testosterone. Men with very low testosterone are also more likely to become obese.
Losing weight through exercise can increase testosterone levels. Testosterone supplements in men with low testosterone can also reduce obesity slightly.
Testosterone and Heart Disease
Testosterone has mixed effects on the arteries. Many experts believe testosterone contributes to the higher rates of heart disease and high blood pressure that tend to affect men at younger ages. Testosterone deficiency is connected to insulin resistance, obesity, and diabetes. Each of these problems increases cardiovascular risk. Men with diabetes and low testosterone also have higher rates of atherosclerosis, or hardening of the arteries.
Testosterone and Other Conditions
Low testosterone often exists with other medical conditions including depression and erectile dysfunction.
For men with low testosterone levels as measured by a blood test who also have symptoms of low testosterone, such as decreased libido, loss of muscle mass, lethargy, and falling asleep after meals, the decision to take testosterone replacement is one to make with your doctor.

Bottom Line: Testosterone is the male hormone produced in the testicles and is responsible for a man’s overall health. Deficiency can lead to many life threatening disorders that can be treated with hormone replacement therapy.

The Power of Poop-You Won’t Believe This New Treatment For Many Diseases-It May Just Scare the Sh#@ Out Of You

June 26, 2011

Throughout civilization, human feces has posed considerable health hazards; when it gets into the water supply, for instance, a lot of bad things can happen. But in recent years, a variety of medical researchers, many of them gastroenterologists, have pushed for a greater understanding of poop, and have made some startling discoveries. It is possible that many medical illnesses — from intestinal problems to obesity to disorders like multiple sclerosis and Parkinson’s and Alzheimer’s and perhaps even cancer — are related to bacteria in our colons. Now read this: the solution therefore may lie in transplanting healthy bacteria from a normal person into a sick person. This procedure, fecal transplant, was developed by a gastroenterologist in Sidney, Australia. A fecal transplant consists of taking the stool from a healthy person, mixing it with a saline solution, and inserting it into the colon of an ill person. Fecal matter is now much more than solid waste. We now know that it is largest organ of the body. It contains about nine times more living bacteria than the body contains human cells. So, in a manner of speaking, we are 10 percent human and 90 percent poop. Bacteria are capable of producing antibiotics. An example is penicillin, which was discovered when Alexander Fleming saw that some bacteria caused other bacteria to stop growing. When the stools infected with a bad bug or bacteria and causes an illness, the bacterial flora may be altered and stop producing antibodies. Using another person’s normal bacteria and return the bacterial flora to normal and resume making the good antibiotics. Bottom Line: All that stinks is not all bad. Healthy fecal bacteria may be helpful in treating various disease states such as ulcerative colitis, diarrhea, constipation, and maybe even multiple sclerosis.

Sitting Disease-A Lethal Condition Can Be Cured By Standing At Your Desk

June 23, 2011

According to a poll of nearly 6,300 people by the Institute for Medicine and Public Health, the sitting disease develops from our sedentary jobs and lifestyles. The 50 or more hours spent sitting each week is a hot topic for medical experts because of the relationship been sitting and obesity, diabetes, heart disease, and even early death.

What’s so bad about sitting? In a nutshell, when you’re seated your muscles’ electrical activity drops, which incites a cascade of unwanted metabolic effects. The body’s calorie-burning mechanisms slow and insulin efficiency drops, increasing the risk of diabetes. Obesity becomes a concern because enzymes that break down lipids and triglycerides also drop, bringing levels of good (HDL) cholesterol down with them. What’s more, even regular exercise doesn’t seem to outweigh the ills of sitting through the workday.

Luckily, experts are taking a stand, literally, to combat this Sitting Disease. The easiest solution is simply standing at your desk.

Consider adjusting your desk to standing height. Standing at your desk results in an increase in calorie-burning and better posture benefits. However, there’s a tradeoff and your feet will feel tired at the end of the day.

It doesn’t matter if you go running every morning, or you’re a regular at the gym. If you spend most of the rest of the day sitting — in your car, your office chair, on your sofa at home — you are putting yourself at increased risk of obesity, diabetes, heart disease, a variety of cancers and an early death. In other words, irrespective of whether you exercise vigorously, sitting for long periods is bad for you.

So what’s wrong with sitting?

 The answer seems to have two parts. The first is that sitting is one of the most passive things you can do. You burn more energy by chewing gum or fidgeting than you do sitting still in a chair. Compared to sitting, standing in one place is hard work. To stand, you have to tense your leg muscles, and engage the muscles of your back and shoulders; while standing, you often shift from leg to leg. All of this burns energy.

People who sit for many hours found that those who took frequent small breaks — standing up to stretch or walk down the corridor — had smaller waists and better profiles for sugar and fat metabolism than those who did their sitting in long, uninterrupted chunks.

Bottom Line: Your chair is your enemy.  Beware of your chair!

Want To Lose Weight? Check Your Testosterone Level!

September 15, 2010

This blog was excerpted from an article by Dr. Julius Goepp in Life Extension, October 2010.

Low testosterone promotes abdominal obesity in aging men. As men age, many men become trapped in a vicious cycle that leads to life-threatening abdominal obesity. No matter how much men exercise or how little they eat, these men are unable to shed this excess weight that accumulates in their belly. It has been demonstrated that low testosterone and obesity reinforced each other, trapping men in a spiral of weight gain and hormonal imbalance. In spite of this widespread threat to men’s health, most physicians do not test for testosterone levels in their obese male patients. If they did, millions of men could be protective against the scourge of metabolic syndrome, type 2 diabetes, high blood pressure, atherosclerosis, erectile dysfunction and cancer. If you haven’t to be one of these plagued  men, please have your testosterone blood levels measure and share the results with your doctor. Experts now recommend testosterone testing for most men of middle-aged men and beyond.   There is compelling evidence for the role of testosterone therapy as a means of promoting weight loss.

A Lark in the Park May Put a Correction in Your Erection

June 20, 2010

I recently attended the American Urologic Society meeting in San Francisco, May 31-June 3, and I attended a program about male sexual dysfunction.  I was pleasantly surprised to hear of a study that reported that men who exercised on a regular basis were better performers in the bedroom.  Those men who exercised regularly had better erections and had sexual intimacy more frequently those men who led sedentary life styles.  Even men who had  moderate exercise, like take a brisk walk for 30 minutes four times a week were much less likely to have sexual dysfunction than those who were walkers.  It was noteworthy that even moderate exercise such as yoga and walking were just as beneficial as strenuous exercise such as jogging and swimming.

The researches from Duke University suggested that exercise may increase blood flow through the penis, making it easier to get an erection.  Also, working out may make men feel better about themselves and that in turn may improve sexual prowess.

Bottom Line: Men, you may just be able to keep that Viagra, Levitra, or Cialis tablet in the medicine cabinet if you started a regular exercise program.  The best would be to take that walk with your partner as your relationship will also improve if you take time to be with each other on a regular basis.
