A Walk A Day, and Not An Apple, Keeps the Doctor Away
The baby boomers have arrived in large numbers. They are taking responsibility for their health and are eager to stay well and out of the doctor’s office. This blog will discuss the importance of exercise, even walking, to make you healthy and well. This blog will emphasize exercise and not weight loss as the road to good health and longevity.
A brisk 20 minute walk each day could be enough to reduce your risk of early death. A study of over 334,000 European men and women found that twice as many deaths may be attributable to lack of physical activity compared with the number of deaths attributable to obesity, but that just a modest increase in physical activity could have significant health benefits.
Physical inactivity has been consistently associated with an increased risk of early death, as well as being associated with a greater risk of diseases such as heart disease and cancer. Although it may also contribute to an increased body mass index (BMI) and obesity, the association with early death is independent of an individual’s BMI.
To measure the link between physical inactivity and premature death, and its interaction with obesity, researchers analyzed data from 334,161 men and women across Europe participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) Study. Over an average of 12 years, the researchers measured height, weight and waist circumference, and used self-assessment to measure levels of physical activity. The results are published today in the American Journal of Clinical Nutrition.
TThe authors estimate that doing exercise equivalent to just a 20 minute brisk walk each day — burning between 90 and 110 kcal (‘calories’) — would take an individual from the inactive to moderately inactive group and reduce their risk of premature death by between 16-30%. The impact was greatest amongst normal weight individuals, but even those with higher BMI or with obesity saw a benefit.
Using the most recent available data on deaths in Europe the researchers estimate that 337,000 of the 9.2 million deaths amongst European men and women were attributable to obesity (classed as a BMI greater than 30): however, double this number of deaths (676,000) could be attributed to physical inactivity.
Bottom Line: So what is the message?
This is a simple message: just a small amount of physical activity each day could have substantial health benefits for people who are physically inactive. Although we found that just 20 minutes would make a difference. Physical activity has many proven health benefits and should be an important part of our daily life.
