Effects of Anxiety on Caloric Intake and Satiety-Related Brain Activation in Women and Men
I'm sure every survivor has anxiety about 100% recovery. So ask your doctor to address the root cause of that rather than prescribing lazy diet counseling. I don't give a shit that 100% recovery is not possible right now. What is your doctor doing to solve that problem? ANYTHING AT ALL?

Abstract
OBJECTIVE:
To test the relationship of anxiety to caloric intake and food cue perception in women and men.
METHODS:
Fifty-five
twins (26 complete, 3 incomplete pairs; 51% women) underwent 2
functional magnetic resonance imaging (fMRI) scans (before and after a
standardized meal) and then ate at an ad libitum buffet to objectively
assess food intake. State and trait anxiety were assessed using the
State-Trait Anxiety Inventory. During the fMRI scans, participants
viewed blocks of fattening and nonfattening food images, and nonfood
objects.
RESULTS:
In
women, higher trait anxiety was associated with a higher body mass
index (BMI) (r = 0.40, p = .010). Trait anxiety was positively
associated with kilocalories consumed at the buffet (r = 0.53, p = .005)
and percent kilocalories consumed from fat (r = 0.30, p = .006),
adjusted for BMI. In within-pair models, which control for shared
familial and genetic factors, higher trait anxiety remained associated
with kilocalories consumed at the buffet (p = .66, p = .014), but not
with BMI. In men, higher state anxiety was related to macronutrient
choices, but not to total caloric intake or BMI. FMRI results revealed
that women with high trait anxiety did not suppress activation by
fattening food cues across brain regions associated with satiety
perception after eating a standardized meal (low anxiety, mean
difference = -15.4, p < .001; high anxiety, mean difference = -1.53, p
= .82, adjusted for BMI).
CONCLUSIONS:
In
women, trait anxiety may promote excess caloric consumption through
altered perception of high-calorie environmental food cues, placing
women with genetic predispositions toward weight gain at risk of
obesity.
