Anorexia nervosa -- an eating disorder that makes people obsessive about their weight -- could alter the brain circuits and impact its taste-reward processing mechanisms, especially for sugar, a study has found. While most people like sweet tasting things, those with eating disorders associate the taste with weight gain and try to avoid it. The study showed that the brain activation in the anorexia group was inversely connected with any pleasant experience of eating sugar. Those who are already worried about shape and weight become even more concerned. And a strong response that says "feed me" might be overwhelming and trigger more food restriction instead of eating.
