Wake Up Call

This article is kind of scary and definitely a wake up call. Yet another reason to train for the 3 day walk or get out and exercise in general.


The Facts on Weight Management and Cancer

--By The American Institute of Cancer Research

Many pressing reasons exist to avoid being overweight or obese and, unfortunately, cancer is one of them. It has long been known that excess weight increases the risk of heart disease, stroke and type-2 diabetes. But, fewer people know about the frightening link between cancer and obesity. In a recent survey conducted by the American Institute for Cancer Research (AICR), only 25 percent were aware of the cancer-obesity association.

Yet science clearly demonstrates that obesity increases cancer risk. A recent report by the World Health Organization's International Agency for Research on Cancer estimates that being overweight and inactive accounts for one-fifth to one-third of all breast, colon, endometrial, kidney and esophageal cancers. In the U.S. alone, that estimate represents between 102,000 and 135,000 cases each year. Strong evidence also associates obesity with higher risk of cancers of the pancreas, uterus, prostate and ovary.

The Cancer-Obesity Link
Researchers predict that the epidemic growth in rates of obesity and overweight will cause cancer rates to soar 50 percent worldwide by 2020.

Why? Cancer is a complex disease, and many factors probably explain the increased cancer risk caused by excess weight. New findings suggest that fat cells constantly secrete a variety of hormones and other growth factors into the bloodstream. In obese and overweight individuals, greater amounts of these hormones and growth factors are continually pumped into the bloodstream. Cells are urged to grow and divide at an accelerated rate. Thus, according to this theory, the random mutations that can lead to cancer are more likely.

Are You at Risk?
How should you determine if you're at risk? Most of us know when we gain weight. Clothes no longer fit. The mirror becomes an irritating reminder, and the scale is permanently hidden under the bed.

Many of us, however, learn to overlook these signs. Fortunately, science currently offers two methods of assessing body weight. Neither is perfect, but they both tell you whether you need to take steps to control your weight and, consequently, lower your risk of cancer and other chronic diseases.

1. Body Mass Index (BMI) is one common method used to measure overweight and obesity levels. This BMI chart shows the range of healthy and unhealthy weights for different heights. (BMI may not be an accurate indicator for athletes, the elderly, children or people less than 5 feet tall.)
2. Waist Circumference is a second, complementary means of assessing possible risk due to excess body fat. Place a tape measure around your waist immediately above the tip of your hipbone. Measure right after exhaling. For women, a waist measurement of 35 inches or more indicates high risk. For men, the significant figure is 40 inches or more.

In most cases, the BMI and waist measurements will confirm each other. But some people with a BMI of 30 or below whose waist measurement indicates high risk should consider themselves at high risk.

Practice Precaution
Even if both of your measurements show that you're in a healthy range, don't become complacent. In our modern society, eating temptations abound. Remember that the easiest way to manage overweight is to never let it happen. After reviewing the existing research on the subject, a panel of scientists assembled by AICR concluded that everyone should avoid being overweight. They suggest limiting weight gain during adulthood to 11 pounds in order to reduce the risk of cancer.

If your BMI or waist measurement indicates excess weight, it's time to take steps to lower your risk for cancer and other chronic diseases. Forget about previous, unsuccessful attempts. Aim for a modest reduction. Even the loss of a few pounds will reduce the risk of disease.

A Healthy, Longer Life
If you're concerned about lowering your cancer risk and avoiding other chronic diseases associated with excess body fat, you should be concerned about your weight. All adults who have a BMI above 24.9 are considered at risk for premature death and disability.

By gradually incorporating AICR's recommendations into your daily habits, you should be able to reach and maintain a healthier weight. That will mean reduced risk for chronic diseases, a greater sense of well being and the pleasure that comes from regular exercise and varied, healthy eating.

AICR Diet and Health Guidelines for Cancer Prevention

1. Choose a diet rich in a variety of plant-based foods.
2. Eat plenty of vegetables and fruits.
3. Maintain a healthy weight and be physically active.
4. Drink alcohol only in moderation, if at all.
5. Select foods low in fat and salt
6. Prepare and store foods safely.
