We have a wonderful deli/bakery nearby that has great, healthy food, and very yummy, not-so-healthy treats – cookies, éclairs, pastries… very tempting stuff. Every once in awhile I’m seduced by these delicacies, and when I am, I almost always notice something afterwards: I don’t feel as good as I did before.
It’s not a severely bad feeling, and I can easily ignore it if I want to. But if I pay attention to the sensations in my body, there’s a clearly different feeling from my insides; it’s not as pleasant as it was before I had eaten the sugar and fat filled morsel.
This is the key to making our fight against bad habits a fair fight.
About 80 percent of the nerves connected to our viscera are afferent – meaning they send signals to our brain from our organs. These are sensory nerves, designed to give feedback about what’s happening within our bodies.
Until recently medical texts claimed that there was little or no sensory information coming from our organs. We now know that’s not true; there are well understood pathways from a part of our vagus nerve that send these sensory signals. Interestingly, Charles Darwin wrote about this over 100 years ago, but it never became widely appreciated until now.
But it’s also extremely common for us as we grow and deal with our challenges and goals – and peer pressure, and impatience of our fellow humans – to learn to ignore much of what these signals are telling us.
By ignoring the sensations of our bodies, we effectively deprive ourselves of one of our great strengths to overcome short term temptation… including the cravings for sugar and refined carbohydrates that have been fueling the alarming rise in obesity in recent decades.
In Walter Mischel’s “Marshmallow Experiment,” Young children were presented with a marshmallow (or cookie or other treat – they were given some options from which to choose), then given the opportunity to earn a second treat if they could wait for the experimenter to return – about 15-20 minutes later.
A lot of kids had a very hard time doing this, until they were told a very simple secret: they could imagine the treat as though it were only a picture of a treat. This turned the sensory stimulation of that immediately seductive treat into an abstract thought; and this very simple shift in attitude allowed children – who had zero resistance before – to now almost miraculously resist temptation.
By turning the immediate temptation into an abstraction, it lost its seductive power.
What does this have to do with body sensations, afferent nerves, and obesity?
