A study found that patients with ED have altered brain responses to eating desserts. (http://www.dsm.psychiatryonline.org/article.aspx?articleid=1695221&RelatedWidgetArticles=true). Basically, the part of the brain (usually the insula) that becomes 'happy' or excited when we normally eat desserts does not function properly in ED. Instead of finding that eating something sweet makes us happy, our brains interpret this as being dangerous, frustrating, and unrewarding. As a result, our brains send messages that say 'desserts are not good. They are bad. Avoid them because they make you feel terrible. Do not eat desserts'. Can you see why eating sweet things would be so difficult for someone with ED? Their brain is constantly sending signals to AVOID this!
Is there a cure? Maybe. For me, eating anything used to be so hard - but desserts were extra hard. My brain was telling me 'NO!', and I was also scared of eating and gaining weight. At first, I did not eat many sweets. I remember in my first week of recovery, my 'snacks' were always fruits, nutrition bars, etc. Now, that isn't wrong - it is good to have a varity of things each day. What was wrong was that I ended up feeling so full after eating enough fruits to get my calorie intake, and I still kind of craved desserts. I wanted to try a brownie for so long, but my brain was saying NO. Eventaully, one day, I got tired of this constant battle. I told myself that I was going to sit myself down and eat a small brownie as an experiment. JUST ONE. And if I hated it, I would never have to have one again. If I liked it, maybe I could try other things too. So I did. I got a brownie for a snaak. And I liked it. NOTE: some people have tendancy to binge. If this is you (be honest) then doing this with a therapist or medical team may help you avoid the urge to binge on sweet foods.
