A deficit discovered in reward-based learning, specific to food, among women with obesity highlights the behavioral aspects of the epidemic and holds potential for combating it, according to a report published in Current Biology.
"Women with obesity were impaired at learning which cues predict food and which do not, but had no trouble learning similar associations with money," Ifat Levy, PhD, of the Yale School of Medicine, told Endocrine Today.
The impairment was markedly different in women with obesity vs. those with normal weight, and not seen in men, in an appetitive reversal paradigm conducted by Zhihao Zhang, a PhD candidate at Yale University, and colleagues, including Levy.
"Although we do not know whether this impairment is a cause for obesity or its effect, this finding provides a link between reward learning and obesity, which can now be used to further probe these questions," Levy said.
The journal article is paywalled, but an abstract is available.

FWIW, dish size is important enough that weight watchers, e.g., recommends using smaller plates. I'm not sure whether it's an always true or just for some people, but it's true often enough to have been noticed.

Doesn't surprise me, and good on WW! Yeah, it's probably not every dieter, but enough of 'em to notice, obviously.
