Is The Obesity Epidemic Killing Us?

Author: Dr. Stephen Chaney

Does obesity cause cancer?

does obesity cause cancerYou probably already know that we are in the midst of a world-wide obesity epidemic. If not, here are some of the alarming statistics that characterize that epidemic:

  • The global prevalence of obesity has increased by 27.5% between 1980 and 2013.
  • 35% of the adult population worldwide is now overweight (BMI ≥ 25), including 12% who are classified as obese (BMI ≥30).
  • According to the NIH the situation is even worse in developed countries like the US where 75.1% of adults are now overweight, including 35.7% who are obese, and 6.3% who are very obese (BMI ≥40).

Unfortunately, overweight and obesity are not benign. You probably already knew that those excess pounds increase your risk of diabetes, heart disease, kidney failure and much more. You probably also knew that those excess pounds increase your risks of certain types of cancer such as colon, rectal, kidney, pancreatic, postmenopausal breast, ovarian and uterine cancer.

It’s been a little more difficult to determine just how much obesity increases cancer risk. However, a recent study suggests that the increased risk could be quite significant. In fact, if this study is correct, obesity may only be second to smoking as a preventable cause of cancer. The truth might just scare you skinny!

Does Obesity Cause Cancer?

cancer epidemicThe International Agency For Research On Cancer did a worldwide study, (Arnold et al, The Lancet Oncology 16: 36-45, 2015),  in which they looked at the effect of BMI on cancer incidence in adults aged 20 years or older. The BMI data was collected in 2002 and was segregated by sex and age groups. Recognizing that cancer takes decades to develop, they then collected data on newly diagnosed cancers in adults 30 and older in the same countries in 2012.  They were determined to get closer to answering the question, does obesity cause cancer?

By comparing BMIs in 2002 with the incidence of newly diagnosed cancers 10 years later they were able to calculate the effect of excess body weight (BMI ≥25) on cancer incidence. The results were startling:

  • They estimated that 481,000 new cases of cancer in 2012 in adults over 30 were attributable to excess weight.
  • That represents 3.6% of all new cancer cases, which makes overweight second only to smoking as a preventable cause of cancer.
  • Uterine cancer, postmenopausal breast cancer, and colon cancer accounted for 63.6% of all cancers caused by overweight. Other cancers affected by excess weight were rectal cancer, pancreatic cancer, kidney cancer, gallbladder cancer, and ovarian cancer.
  • The effect of excess weight on cancer risk was almost 3-fold greater for women (5.4% of new cancer cases) than for men (1.9% of new cancer cases).
  • In North America 111,000 new cases of cancer in 2012 for adults over 30 were attributable to excess weight. That represents 3.5% of all new cancers in men and 9.4% of all new cancers in women.
  • A quarter (about 118,000) of the worldwide cancer cases related to high BMI in 2012 could be attributed to the increase in BMI that has occurred since 1982.

The authors concluded “These findings emphasize the need for a global effort to abate the increasing numbers of people with high BMI. Assuming that the association between the high BMI and cancer is causal, the continuation of current patterns of population weight gain will lead to continuing increases in the future burden of cancer.”

What Does This Study Mean For You?

We have to stop kidding ourselves. That excess flab isn’t harmless. It is killing us, and cancer is a particularly gruesome way to go. It’s time to get serious about weight loss. Here are my top 5 tips for lasting weight loss.

  • fad dietsEat healthy low calorie meals and snacks with plenty of protein so that you maintain muscle mass while you are losing fat.
  • Avoid the fad diets. You don’t need to restrict carbohydrates or fats. You just need to focus on fresh fruits and vegetables, healthy proteins and modest amounts of healthy fats and healthy carbohydrates.
  • Find an exercise program you like and stick with it every day.
  • Focus on true lifestyle change rather than short term diets. A good strategy is to make one healthy change at a time rather than trying to do everything at once.
  • Change how you think about food, think about exercise, and think about your ability to make the kinds of changes that will lead to permanent weight loss. Don’t think of yourself as a fat person who is trying to lose weight. Think of yourself as a skinny person who happens to have a few extra pounds that are on their way out.

Of course, getting to a healthier weight isn’t the only change you want to make if you are trying to reduce your risk of cancer. Here are my top 7 lifestyle change suggestions (besides weight loss) for reducing cancer risk.

  • healthy eatingIf you smoke, stop. No ifs, ands, or buts. Smoking is still the #1 cause of cancer.
  • Eat a healthy diet (including supplements to fill the gaps).
  • Eat plenty of fresh fruits and vegetables, especially those that are good sources of cancer-fighting antioxidants, carotenoids, flavonoids, and polyphenols.
  • Eat fish and fish oil supplements to make sure that you get plenty of omega-3 fatty acids.
  • Minimize saturated fats and avoid trans fats. Substitute olive oil for vegetable oils whenever possible.
  • If you drink alcohol, drink it in moderation.
  • Avoid sun exposure as much as possible, and use sunscreen when outdoors.
  • Eat healthy proteins.
  • Minimize consumption of red meats and processed meats.
  • Use chicken, fish and vegetable proteins whenever possible.
  • Soy protein is particularly helpful for reducing the risk of breast cancer. (Yes, those scary blogs about soy and breast cancer are wrong. For accurate information, just go to https://healthtipsfromtheprofessor.com and type soy in the search box).
  • Get plenty of exercise.
  • Get regular check-ups.

So, does obesity cause cancer?  I think you now know the answer.

 

The Bottom Line

 

  • A recent study has shown:
  • 481,000 new cases of cancer worldwide each year are attributable to excess weight.
  • That represents 3.6% of all new cancer cases, which makes overweight second only to smoking as a preventable cause of cancer.
  • Uterine cancer, postmenopausal breast cancer, and colon cancer accounted for 63.6% of all cancers caused by overweight.
  • The effect of excess weight on cancer risk was almost 3-fold greater for women (5.4% of new cancer cases) than for men (1.9% of new cancer cases).
  • In North America 111,000 new cases of cancer for adults over 30 are attributable to excess weight. That represents 3.5% of all new cancers in men and 9.4% of all new cancers in women.
  • That excess flab isn’t harmless. It is killing us, and cancer is a particularly gruesome way to go. For my top 5 tips for lasting weight loss and my top 7 tips for reducing your risk of cancer, read the article above.

What Is The Pectineus Muscle And Why Is It Important?

Spring Is In The Air

spring floridaI remember as a child we sang “Though April showers may come your way…they bring the flowers that bloom in May…”

Of course, here in Florida we are blessed with flowers all year, but there’s still a lovely feeling that happens in Spring.  It’s still cool enough most days to go out running, and the humidity is still low.  Traffic will soon be easing up as our friends from the north start their trek back home, and daylight savings time is giving us more time to get to the beach for sunset.  Lovely!

Fun Facts About Spring….

  • The earliest known use of the term “spring cleaning” was in 1857
  • The word “spring” has been used for the season since the 16th century
  • The first day of spring is called the vernal equinox
  • On the first day of spring, the sunrise and sunset are about 12 hours apart everywhere on earth
  • Spring fever isn’t just a saying. Experts say the body changes due to the temperature and can cause an upset in your health.
  • The actual start of spring varies from March 19th to the 21st, but it is commonly celebrated on the 21st.

Do you like to garden?  Now is the perfect time to get your gardens planted so you’ll have home grown veggies for the entire summer.  For me, it’s also a great time to do some spring cleaning and get the house in order before the summer closes all the windows and the air conditioning becomes our indoor relief.

But these activities can also cause a strain on muscles, so don’t forget to take care of yourself. If you put too much strain on muscles you haven’t used all winter, you can develop problems and need groin pain relief.

 

A Tiny Muscle Can Cause Groin Pain

groin pain relief pectineusLately I’ve had several clients come in because of groin pain that has their medical practitioners stumped.  Their symptoms are varied, but most complain that it feels like they hit their pubic bone with a rubber mallet.  Ouch!

One client loves to ride her horse, but the pain had prevented that for several weeks. Another was considering selling the motorcycle that she and her husband love because she just can’t sit on it anymore.

Several years ago, I had a male client tell me that he had this same pain and he was told it could be his prostrate causing the issue.  Fortunately, that wasn’t he problem at all.

The muscle that caused all these problems, and a lot more, is the Pectineus.

The Pectineus muscle originates on your pubic bone and inserts into the very top of your inner thigh bone (femur).

You can see the Pectineus and surrounding muscles more clearly by going to https://en.wikipedia.org/wiki/Pectineus_muscle

Most muscles have more than one function, and this is true for the Pectineus.  The function we’ll look at today is called adduction.  It brings your leg in toward midline.  If you think of a soccer player kicking the ball with the inside of his ankle, it was the Pectineus that helped draw his leg in so he could do the shot.

Each of my clients had pain while trying to bring their leg out so they could sit on their horse, or on their motorcycle.  The tight muscle was pulling on their pubic bone and causing a severe strain.

This muscle is easier to have someone else treat it for you because of its location but give it a try and see if you can locate & treat it yourself.

 

Groin Pain Relief

To reach the Pectineus, move the ball all the way up to the crease in your leg.  You can do the treatment with a ball, but because of the size of the muscle and its location, it’s easier to do it with your fingertips.

Sit as this athlete is sitting, and even bring your opposite leg up so your foot is flat on the floor.  For example, in this picture, the athlete would bring her right leg up so her right foot is on the floor, and then lean a bit further onto her left hip.  That opens up the area so she can reach a bit easier into the muscle while using her fingertips.

Press into the muscle, being careful to feel for a pulse, and moving if you feel one.  If the Pectineus is in spasm, you’ll know it immediately when you press on it.  If it’s not in spasm, you won’t be able to find it at all.

Remember to stay within your pain tolerance level, this isn’t a “no pain, no gain” situation.  Never go deeper than what feels tender, but not so much that you want to faint. Hold the pressure for 15 seconds. Then let up on the pressure, but keep your fingers in the same place.

Repeat this movement several times. Each time it will hurt less, and eventually it won’t hurt at all.  That’s when the muscle has completely released, and you will have relief from the pain.

It’s as simple as that!

Why stay in pain when it’s so easy to find the muscular source of the problem and eliminate it?
