What if the heat energy of food was not expressed in calories but "daily activities"?
So instead of
* chocolate cake : 500 cal/serving
* chocolate cake : 5k run/serving
Or instead of
* celery : -1 cal/serving
* celery : eat jellybean and lie down / serving
Do you think that would help some people a bit more with portion control?
It might at the very least help celery farmers.
And people with eating disorders!
But seriously; I'd like that. I often think "this is SO not worth the calories." Could I be wrong?
Nope. The values would vary considerably by person. Contrary to popular myth, metabolic differences between people (even for times of day for each person) make hash of what is popularlarly reported as the caloric value of exercise. And...even the reported caloric values of foods are averages with a larger range of variation than most people would care to know.
re: Karl S
Of course it's not perfect.
Nor, as you aptly noted, are calorie counts.
In many ways this was asked with a bit of smirk, but I do think there is some value in rethinking how we quantify the heat energy in foods.
I mean, seriously, why is a 100-calorie pack of anything an appropriate snack size for anyone? Eating anything? At any time of the day?
What if instead that 100-calorie pouch of chips was instead labeled something like
>> The all-new 20-minute walk Doritos! The perfect on-the-go snack for the new healthy you! <<
I wonder if people would eat more/less vis-a-vis a same bag of chips labeled "100-calorie pack" or whatever.
