The endless and usually irritating \u201cwhich is better?\u201d debate between city dwellers and suburbanites came to a grinding halt in 2003 when a study was published showing suburbanites were on average several pounds heavier than their urban counterparts. Suddenly, no matter what compelling arguments suburbanites came up with–better schools, lower crime rates, cleaner air\u2014they were demolished by a withering, \u201cNot worth getting fat\u201d or \u201cIt\u2019s okay for your kids, but love handles are quite a price for good schools.\u201d<\/p>\n\n\n\n
The difference in poundage, geographically speaking, was pretty much attributed to the suburban inactivity that comes from a near-total dependence on cars. Even suburbanites will admit that you need a car for just about every activity imaginable\u2026except getting to your car. And here it\u2019s worth noting I\u2019ve seen shuttle services available at larger shopping malls, sometimes used by older adults and the disabled, but just as often by the morbidly obese.<\/p>\n\n\n\n
But now some experts are saying it\u2019s not suburban living that\u2019s responsible for our rising obesity rates\u2014let\u2019s face it, urban dwellers can be pretty chunky themselves–but rather the overall increase in automobile use during the past half century.<\/p>\n\n\n\n
Professor Sheldon H. Jacobson, PhD, of the University of Illinois recently published his findings<\/strong><\/em> on the relationship between driving and obesity in the journal Transport Policy<\/em>. He views this relationship in terms of energy imbalances. Since we basically sit and do absolutely nothing except breathe when we\u2019re driving, Dr Jacobson sees the annual number of miles driven as a new way to look at time spent being completely sedentary. This sedentary time, virtually equivalent to being asleep, can be added to our other big no-calorie-burner, watching TV (or sitting and staring at your phone, computer, or hand-held game).<\/p>\n\n\n\n The energy we once burned walking to the grocery, chopping wood, tilling fields, grinding corn, or churning butter, for example, is now being burned as energy by the gas in our cars. City dwellers may protest they walk to various shops and stores, but one look at Chicago traffic on a Saturday says otherwise. I rarely see anyone ever actually walking to our local Whole Foods on North Avenue and the parking lot is always jammed to capacity.<\/p>\n\n\n\n Not only have we been rendered inactive by our cars, but every decade we’re eating more and more food every day. We’re piling our plates with fats, sugars, and refined carbohydrates, and then there we sit in front of our dashboards. For those who must drive, you sort of wonder if maybe a stick shift would be preferable to an automatic transmission, just to burn a calorie or two.<\/p>\n\n\n\n Our obesity rates began escalating 60 years ago, in the post-World War 2 years when buying a car became a reality for virtually every middle-class family. Dr Jacobson attributes this weight-gain to the penetration of automobile culture into our lives. And woe if you\u2019re someone who eats in your car, for those completely unburned calories go right from your mouth to your pot belly (the sandwich is well-named).<\/p>\n\n\n\n To verify these insights, statisticians are now tracking obesity rates and car use data in countries like India and China, until recently virtually obesity-free with everyone walking or bicycling everywhere. With the rising middle class in both countries and increased car ownership, no one is surprised that obesity rates are on the rise there too.<\/p>\n\n\n\n Since Dr Jacobson is a computer whiz and data analyst rather than a physician, he\u2019s used his data to determine how many miles per day we need to not drive<\/em> in order to return our weight to normal levels. The answer is eliminating 12 miles from your daily driving, which even he acknowledges is virtually impossible. After all, during these same 60 years of automobile use, we literally redesigned most of America to accommodate our cars. Let\u2019s face it, if you live in Evanston and work in Chicago\u2019s Loop, you\u2019re not going to walk back and forth to work every day (although young Abe Lincoln walked twice that distance every daily for school). You\u2019re not going to start biking home along the shoulder of the Kennedy or Dan Ryan expressways, though expressways in Beijing are built with concrete-wall protected bike lanes.<\/p>\n\n\n\n In my own very health-oriented practice, I have several young couples who instinctively understood the health costs of a car-centered life and made a few well-considered alternative choices. For example, instead of racing to the \u2018burbs at the first positive pregnancy test (\u201cbetter schools,\u201d \u201ca back yard\u201d), they analyzed Chicago Board of Education test scores and rented apartments or purchased modest homes within walking distance of a good school, a nice park, an L stop, and a farmer\u2019s market. They bicycle everywhere, and when they\u2019re compelled to drive they rent a Zipcar. I\u2019m pretty sure neither they nor their offspring will ever have a weight problem.<\/p>\n\n\n\n Now think about your life, your day, and your car. Where might you start to use your car less, and your body more?<\/p>\n\n\n\n Be well,<\/p>\n\n\n\n David Edelberg, MD <\/em><\/p>\n","protected":false},"excerpt":{"rendered":" The endless and usually irritating \u201cwhich is better?\u201d debate between city dwellers and suburbanites came to a grinding halt in 2003 when a study was published showing suburbanites were on average several pounds heavier than their urban counterparts.<\/p>\n","protected":false},"author":2087,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2,50,3,82,27],"tags":[1261,1262,325,614],"class_list":["post-4016","post","type-post","status-publish","format-standard","hentry","category-blog","category-healthy-lifestyle","category-knowledge-base","category-o","category-weight-issues","tag-cars","tag-driving","tag-obesity","tag-overweight"],"yoast_head":"\r\nThe obesity curve<\/strong><\/h3>\n\n\n\n
