LOS ANGELES -- You really want to know what it'll take to work off Thanksgiving dinner? Let's just say you'd better cancel your plans to watch football after dinner, or to go shopping today: It could take you into the weekend to work it all off.
In a bid to focus Americans on controlling their weight, public health advocates have embraced posting calories, labeling nutritional content and offering all manner of helpful and eye-catching logos to draw consumers' attention to "better-for-you choices." But there's mounting evidence that no form of consumer information conveys the potential impact of a food choice on one's weight quite as powerfully as do "sweat equivalents."
Sweat equivalents leave little room for self-delusion. They don't require a hungry teenager at the corner grocery store to know how many calories a day she should be taking in, or what percentage of that total that bag of potato chips represents. They simply say: "If you eat this, this is how long you'd have to jog (or swim, or jump rope or play basketball) to work it off."
In experiments, posting sweat equivalents powerfully steered consumers toward water over sugar-sweetened soda, pretzels over chips, salads over cheeseburgers.
In that vein, CoachUp, a service that connects athletes with private coaches, brings you the "sweat equivalents" of a typical American Thanksgiving.
The average American takes in 4,500 calories on Thanksgiving -- about seven Big Macs' worth of calories.
And here, culled from reputable sources on the energy expenditure of various activities, are a few of the activities you will have to engage in to work off the average American intake on Thanksgiving:
* Run (or play basketball or football) for 7.7 hours;
* Cycle for 15 hours;
* Row (or hike) for 10.3 hours;
* Swim for 10.6 hours, (or bowl for almost twice that long -- 20.6 hours)
If you want to limit Thanksgiving's damage, you might try to alter what scientists call the "energy balance equation" (calories taken in versus calories expended in activity) a little on both sides: Don't go back for thirds on Thanksgiving Day AND plan a long hike or an epic game of flag football after the meal, and run the next day.
