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.

A Simple Treatment To Make Your Eye Pain Disappear

Author: Julie Donnelly, LMT –The Pain Relief Expert

Editor: Dr. Steve Chaney

 

good newsAs the song goes: ”…Summertime and the living is e-a-s-y….”  Here in Florida we know that the living is easy because it’s so hot who wants to be doing anything except either sitting in the shade, or inside in the air conditioning.  Personally, I don’t think this summer was so bad, especially the evenings, but then, I really hate the cold so maybe my opinion is biased.

To stay in alignment with “living is easy,” I’m taking the advice of a few experts who teach easy ways to stay calm, motivated, and happy.  I’m taking a 30-day break from the news.  It’s so much in my face lately that it’s really affecting me in a very negative way.  So far, I’m two days into my 30 days.

I’ve decided that I want to take away some of the stress that seems to be normal for everyone. To that end I was listening to a speaker who was talking about the dangers of stress and what it does to the body.  Really frightening! He was saying that negative news sells and, for example, in the 1990’s in one city of the USA, homicides had gone down 42%, but the local TV station increased its coverage of homicides by 700%.  It’s only gotten worse in 2019.  It’s making us think we live in a dangerous country, and it sure isn’t helping our blood pressure.

To solve that problem, this speaker recommended going on a “news fast” for 30 days. Absolutely no negative news of any kind for a full month.  I’m surrounded by news all day so it’s a challenge, but I’ve found a great substitute:  www.GoodNewsNetwork.org.  Their mission is to be an antidote to the barrage of negativity experienced in the mainstream media.

So, I want to share this with you, and if you have any other good news stations/websites you love, please feel free to share it with me.

I think I’m off to the beach with a big umbrella and a thermos of ice-cold tea!  Living the e-a-s-y life!

Have a relaxing month!

 

Eye Strain And Eye Pain

 

eye pain reliefThis week I had a client come to the office with a situation that is pretty rare.  He described his pain as on his eyeball, which then referred to the entire top half of his skull.  It was like drawing a line that went under his eyes, through his ears, and around his head.  It was definitely a headache but concentrated on his eyes.  He was in desperate need of eye pain relief.

This client works in an industry that has the computer screen changing frequently and he’s needing to locate information on the new screen quickly.  He has experienced eye strain before, but other times just having the weekend off has resolved the problem.  This time the pain didn’t go away.

We don’t ever think about the muscles that move our eyes, but they can get repetitively strained just like any other muscle in the body.  This especially happens if you are watching something that has your eye moving back and forth rapidly, like a game on your computer or phone.

The muscles that are most prone to a repetitive strain injury are the ones on the top of the eye and on the outside of the eye.  I’m not an eye doctor so I can’t explain why these two muscles cause more problems than the others, but my experience has shown this to be the truth.

 

Eye Pain Relief

 

eye pain relief massageThe treatment is simple, but you need to do it cautiously.  If you wear contacts, you’ll need to remove them. The pressure is VERY light.

Put your fingertip directly onto your eyeball and press down GENTLY.

Slide your finger from the top of your eyeball to the outside of your eyeball.

If you find a point where it is tender, that’s the spasm that is putting a strain on your eyeball.  Just leave your fingertip on that point for 30 seconds.

You may even get a light show while doing this, with different shapes and colors.

You’ll find that this simple treatment will soothe tired eyes at the end of the day.  But remember, the pressure needs to be light and gentle.

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