A new study suggests that the more you walk, the less likely you'll gain weight as you age. Researchers followed nearly 5,000 men and women for 15 years and found that a half hour of walking per day reduced the usual weight gain per year by 1 pound among women who were the heaviest at the start of the study.
"Walking is of particular relevance because it is generally an affordable and accessible form of physical activity for most people," writes researcher Penny Gordon-Larsen of the School of Public Health at the University of North Carolina at Chapel Hill and colleagues.
"If we can increase walking participation by Americans, the evidence is strong that we will improve not only weight control but overall public health."
The results appear in the American Journal of Clinical Nutrition.
Walking Prevents Age-Related Weight Gain
It's a fact of life for most Western societies that aging is accompanied by weight gain. Previous studies have suggested that this age-related weight gain may result from a decrease in physical activity as people get older.
Although walking has been shown to promote weight loss and prevent obesity, researchers say this is the first study to look at the long-term effects of walking on weight gain and weight control.
The study examined walking habits and weight gain over a period of 15 years among a group of 4,995 men and women aged 18-30.
The results showed that the average body weight and BMI (body mass index, a measure of weight in relation to height) increased over time, but physical activity and walking decreased.
However, men and women who walked more in the early to middle adult years gained less weight and were more likely to lose weight or maintain their weight than gain weight as they got older.
The anti-weight gain effect of walking was greatest among heavy women. For example, the half hour of walking per day was associated with about 15 fewer added pounds over the 15-year study period. Results were similar but slightly less significant in men.
In an editorial that accompanies the study, Miriam E. Nelson and Sara C. Folta of the John Hancock Center for Physical Activity and Nutrition at Tufts University say this is the first study to demonstrate that walking has a protective effect on long-term weight gain.
"It lays the groundwork for future studies, which will help answer how much walking or physical activity in total is needed to maintain body weight over time."

The ones who don''t cannot be motivated to care. They will always remain fat and will continues to get fatter as they age. They will remain arrogantly supportive of unhealthy indulgences, with the over used phrase, "Life is short. Why should I not do what I want."
I had a discussion with a moderately obese acquaintance last week, and after discussing the unhealthy consequences of losing weight and then gaining it back, she said her philosophy was to just stay where you are. The joke is, that she puts on 10-20 pounds a year and continues to stuff her face every chance she gets. It''s this attitude that adds to the the repulsiveness of the obese person.
drivelphobe: Why don''t you do yourself a favor, and go shove a burger up that hole of yours!!!

Perhaps because some people might care. Just because you know this information doesn''t mean all the other rednecks do.
A predictable, infantile redneck remark. Is that your best attempt at expressing yourself? Are you one those I described in my post?
Go have a diet soda, the burger you so adore and a smoke.
Happy new year to you.
I will aim for two 1 hr sessions as time goes by.
My diet is already pretty decent, but immobility from job and sedentary nature will mean more hurt at time goes by. And I wish to live a longer, prosperous life. To get fatter now would wreak REAL havoc on my knees and everywhere else.
And given I''ve seen 21 year olds and, heck, 8 year olds with guts LARGER than mine, they need to move more or eat better. No more MacCholesterol. Seriously; never mind the physical appearance issue. It WILL be more painful as life goes on.
The UN studied long-lived older people, and found the men who lived longest were those whose lives were still full of activity. The typical healthy older subject was one who carried heavy loads (carefully) over long distances.
That is a working description of walking off extra poundage. Unlike jogging (on pavement or treadmill), walking imposes no impact injury to the joint. For increased load, simply walk faster.
Swimming is also excellent aerobic and impact-free exercise.
Those suffering deteriorating joints will be encouraged to learn unsaponifiable fatty acids (found in avocados) are associated with a sharp reduction of damage and sometimes even a rebuilding of the joint tissue.

In the article, it is pointed out that this is the ''first study to demonstrate that walking has a protective effect on long-term weight gain.'' The need for data to support what might seem obvious but significant cannot be overestimated.
