Does food addiction really exist?
This question was a big subject of controversy at the 2013 conferences of the Binge Eating Disorder Association (BEDA) and the International Association of Eating Disorder Professionals (IAEDP).
Two Sides of the Same Coin
Of those who have strong opinions about the subject, there are probably two sides whose opinions vary the greatest — researchers who study the issue, most recently via brain scans of larger-bodied folks who fall into the “obese” range of the BMI. These professionals tend to support the idea of food addiction.
Then there are the dietitians and therapists who use mindful eating (or attuned eating or intuitive eating — all variations on the same theme of normal eating) to help people who struggle with eating and weight. They tend to question whether food addiction really exists, at least beyond the fact that we’re all dependent on food.
Researchers: Brain Activity Supports Food Addiction Argument
Donuts, Ding Dongs and Doritos
The position of the researchers is that they see regions of the brain “light up” when people are exposed to highly-palatable foods, which generally translates to those foods that most people think they shouldn’t eat but do so anyway. You know the foods — the donuts, Ding Dongs and Doritos of the world.
People With Fewer D2 Receptors Eat More For The Same Degree of Pleasure
And they’ve got brain studies to show that larger-bodied folks tend to have fewer D2 receptors in the brain that are involved in signaling pleasure, so that these folks need to eat more to get the same degree of pleasure from foods as people (usually thinner folks) with more D2 receptors.
They also use the Yale Food Addiction Scale as the tool to measure people’s attitudes about food and determine whether they rank as food-addicted.
Counselors: Other Factors Affect Food And Behavior
The position of the counselors is that other pleasurable things light up those same brain centers. Enjoyable things like music. Are we going to say people are addicted to music because they feel pleasure when they hear it?
Researchers Don’t Seem to Factor In The Impact Of Restricted Eating
What’s more — and this is something I discovered as I prepared to give a talk at IAEDP on how to help binge eaters become attuned eaters — researchers don’t appear to be taking into consideration AT ALL the impact of dieting and the other restricted eating behaviors on the “weight of the nation” or the number of D2 receptors they’re seeing in larger folks.
Brain Receptors Are Reduced In Number And Desensitized By Dieting
Studies clearly show that restricted eating behaviors, such as dieting and plain old worry that food is going to make you fat, cause people to gain weight and also can diminish the number and sensitivity of the receptors. It’s as if the last 50+ years of calorie and weight obsession didn’t happen.
Food Addiction or Restricted Eating Behaviors
The Yale Food Addiction Scale: What Does It Actually Measure?
Finally, if you compare the Yale scale to questionnaires that measure restricted eating attitudes and behaviors, lo and behold, you see very similar questions. Questions like “I find that when I start eating certain foods, I end up eating much more than planned” or “I find myself continuing to consume certain foods even though I am no longer hungry” or “Not eating certain types of food or cutting down on certain types of food is something I worry about.” Which makes me question just what is the scale really measuring — food addiction behaviors or restricted eating behaviors?
As I said at BEDA where I chaired a panel discussing how to effectively treat binge eating disorder, one thing I have learned in the last thirty years of working with women who struggle with eating and weight, is to listen to what they have to say.
I am not going to tell someone that a certain food or ingredient such as sugar can’t drive her to eat out of control. I tend to not believe in absolutes — we need to leave room for individual differences.
Science Needs To Account For All The Variables
But I will say it’s not fair to make pronouncements based on faulty data. And that’s what I fear is going on with the current research. If we don’t take into account all the variables, we aren’t going to get clear answers.
I also encourage us all to start at the same place so we can compare apples to apples. That is, if people aren’t eating regular, well-balanced meals that include plenty of whole foods, and aren’t viewing all foods from a neutral place — not labeling them as good or bad or fattening or “I shouldn’t eat” or “I can’t eat without going out of control” — more variables that can muddy the answers come into play.
I daresay that many of the larger-bodied folks who turn up as study subjects are people who have struggled for years with on-again, off-again dieting and worry about food and weight. Their bodies are likely malnourished and out of balance, and they’ve likely got lots of anxieties about food. That must be taken into account when conducting the studies and analyzing their results.
What We Have Seen Repeatedly In Our Program At Green Mountain
Once women get their bodies into balance physically and become curious about how food affects them, rather than pre-judging how they are going to feel when they eat it, and often, getting more in their lives than worry about food and weight, the vast majority find it doesn’t have the power over them they thought it did. So I will admit my bias on the subject, but, again, I always leave the door open for the real expert to weigh in. That expert is the individual with her own experience in her own body.
Still, I always say, why restrict something if you don’t have to?
