All Entries For food addiction
"I'm fat because of Oreo cookies!" screamed the woman as she entered the weight-loss class I was coaching last week. In hand, she waved the press release from Connecticut College, which blared the warning, "Oreos are just as addictive as drugs!"
"I am addicted to certain foods, just like those rats were addicted to Oreo cookies," she continued on. "It's supposed to be worse than being addicted to cocaine. How am I ever going to be successful with my weight loss?" Read More ›
Greetings to everyone. I'm thrilled to share this guest blog on DailySpark.com to share my wit and wisdom on all things healthy living. The SparkPeople community is a powerful and potent network of wonderful folks supporting one another as they strive to achieve mental and physical fitness through a healthier lifestyle. Kudos to all of you for doing your best to live the rich and rewarding life each of you so deserves.
This blog is all about the brand new science of food and addiction. As a physician and scientist and Pew Foundation scholar in nutrition and metabolism, I have devoted years to studying this issue and am thrilled to see that scientists around the globe continue to produce brilliant work to help people manage what is now emerging as a major problem in the field of weight management. Even the Secretary of Health and Human Services, Kathleen Sebelius, noted in a recent pronouncement that a new and significant cause of overweight and obesity is food addiction.
SparkPeople has done a masterful job of enlightening the community about this cutting-edge new science. I've been following the personal journeys of so many people who are struggling with cravings, binges and addictive urges for what we now call the hyperpalatables--sugary/fatty/salty/refined/processed food combinations.
Let's meet Samantha, one of my patients, who is featured in my book, The Hunger Fix, which described the new science in consumer-friendly terms.
The beast never went away, it was just hiding, waiting to strike. I was blindsided, and by the time I really consciously realized what was happening, it was too late. A clear consciousness of what was happening didn't emerge until real physical terror— I woke up choking, because stomach acid was running up my throat into my mouth from my anxiety. I had bought bags of candy, intending to make Christmas cookies for everyone, but suddenly I had to feed the beast. I hid candy in the freezer, the car, even wrapped in a sock strategically placed through- out the house. I felt ashamed, tricked, embarrassed, mortified, and angry. The anger fired me up and gave me strength to face the beast. I'm nauseous just admitting my darkest moments of addiction— my friends, family, and husband would be shocked to know! The Hunger Fix, pages 166-167
Thanks to the advent of specialized scans that allow researchers to peer into the brain, we've discovered what is now believed to be the basic mechanisms underlying all addictions. This is what is happening inside your brain:
- Your Reward Center is Hijacked: In any addictive state, we now know that the reward center in your brain undergoes organic changes. In the case of food, it's usually the hyperpalatables that cause most of the problems. Overexposure to them causes too much dopamine (the brain chemical that helps you feel reward and pleasure) to flow, overwhelming the brain. The brain can't handle this long term and a primal mechanism kicks in resulting in a decrease in the total number of dopamine receptors (the only way to feel reward is when dopamine bonds with its receptor). The bad news is that as a consequence of this downshift in receptors, your own perception of reward significantly decreases. One cupcake is not enough. 2, 3, 20 can't do it. There's no period to the end of that sugary/fatty/salty sentence. This is how the addictive cycle begins. If you have addiction genetics in your family line, this entire process is magnified. You do not have to have addiction genetics to become food addicted. You just need that overexposure from your living environment.
- Your Executive Center is Impaired: People with food addictions are constantly told "just use moderation for heaven's sake!". The problem is that the brain center that controls impulses (prefrontal cortex or PFC) is also where your willpower and discipline is housed. Scientists have discovered that in all addictions, the PFC is damaged and impaired. Try telling a food addict or an alcoholic in the middle of their respective binges to use moderation. This is not an excuse to stay out of control. It's just a scientific fact that is taken into consideration when a detox and recovery program are created.
Do you ever feel like you just can't stop yourself from overeating? Are there some foods that are extremely hard for you to resist even when you aren't hungry? Is it very hard to stop eating once you've started, even though your intention is to have just a small amount?
If so, you're definitely not alone. But what's going on here? Is it possible you might be addicted to food?
Not long ago, most experts would have said "no." The prevailing wisdom was that people with the right biological susceptibility might get addicted to drugs or alcohol, but food was just not an addictive substance in the same league with, say, alcohol, crack cocaine or meth. After all, people don’t get addicted to broccoli, oatmeal, or chicken breasts. Even though eating certain foods (usually refined sugars and/or fatty, salty foods) is known to increase appetite in some people and/or turn off the satiety signals that normally would tell them when to stop eating, and even though certain psychological problems can lead some people to become compulsive eaters, these problems were not seen as the same kind of thing as a true substance addiction.
More recently, though, the evidence has been painting a different picture… Read More ›
