abstract = {The estimates we do of the energy content of different
foods tend to be inaccurate, depending on several factors.
The elements influencing such evaluation are related to the
differences in the portion size of the foods shown, their
energy density (kcal/g), but also to individual differences
of the estimators, such as their body-mass index (BMI) or
eating habits. Within this context the contribution of brain
regions involved in food-related decisions to the energy
estimation process is still poorly understood. Here,
normal-weight and overweight/obese women with restrained or
non-restrained eating habits, received anodal transcranial
direct current stimulation (AtDCS) to modulate the activity
of the left dorsolateral prefrontal cortex (dlPFC) while
they performed a food energy estimation task. Participants
were asked to judge the energy content of food images,
unaware that all foods, for the quantity presented, shared
the same energy content. Results showed that food energy
density was a reliable predictor of their energy content
estimates, suggesting that participants relied on their
knowledge about the food energy density as a proxy for
estimating food energy content. The neuromodulation of the
dlPFC interacted with individual differences in restrained
eating, increasing the precision of the energy content
estimates in participants with higher scores in the
restrained eating scale. Our study highlights the importance
of eating habits, such as restrained eating, in modulating
the activity of the left dlPFC during food appraisal.},
