Just Thinking About Exercise...

...leads people to overeat.  I am a marketing professor, and this study, by another marketing professor from Cornell named Brian Wansink, was quite clever.  Participants were given written scenarios about exercise or shopping, then rewarded with a "thank you bag" into which they could scoop as many M&Ms and as much Chex Mix as they wanted.  Those who read about exercise scooped up 60% more of the M&Ms and 52% more of the Chex Mix than those who read a scenario about shopping.

So as I mentioned yesterday, exercise does not help people lose weight, since people tend to "compensate" themselves for their virtuous acts of exercising by consuming more.  Now I learn that you don't even need to actually exercise, you can skip directly to caloric compensation.
