the easy accessibility of highly palatable foods together with our innate preferences for such foods, can increase the likelihood that vulnerable people will “misuse” food, in much the same way that addicts misuse other drugs to blunt negative emotional states, such as depression, anxiety, loneliness, boredom, anger or interpersonal conflict.

Regular readers must be well aware of the close link between addictions and some forms of overeating. This topic is now nicely addressed in a commentary by Valerie Taylor (McMaster, Hamilton), Claire Curtis and Caroline Davis (both York University, in this week’s edition of CMAJ.
As they discuss,
“The concept of food addiction, which more accurately may reflect addiction to specific components of food, can be described in much the same way as other addictive behaviors. Both food and drugs induce tolerance over time, whereby increasing amounts are needed to reach and maintain intoxication or satiety. In addition, withdrawal symptoms, such as distress and dysphoria, often occur upon discontinuation of the drug or during dieting. There is also a high incidence of relapse with both types of behavior.“
Health professionals and decision makers charged with tackling the obesity epidemic would do well to familiarize themselves with the science of addictions and utilize learning’s from addiction management in their counseling of patients presenting with excess weight.
