Abstract<\/h2>\n
Background Increased portion size is an essential contributor to the current obesity epidemic. The decision of how much to
\neat before a meal begins (i.e. pre-meal planning), and the attention assigned to this task, plays a vital role in our portion
\ncontrol.
\nObjective We investigated whether pre-meal planning can be influenced by a shift in mindset in individuals with overweight
\nand obesity in order to influence portion size selection and brain activity.
\nDesign We investigated the neural underpinnings of pre-meal planning in 36 adults of different weight groups (BMI <
\n25 kg\/m2 and BMI \u2265 25 kg\/m2) by means of functional magnetic resonance imaging. To examine the important role of
\nattentional focus, participants were instructed to focus their mindset on the health effects of food, expected pleasure, or their
\nintention to stay full until dinnertime, while choosing their portion size for lunch.
\nResults We observed that participants of all weight groups reduced their portion size when adopting a health mindset, which
\nwas accompanied by enhanced activation of the self-control network (i.e. left prefrontal cortex). Fullness and pleasure
\nmindsets resulted in contrasting reward responses in individuals with overweight and obesity compared to normal-weight
\nindividuals. Under the pleasure mindset, persons with overweight and obesity showed heightened activity in parts of the taste
\ncortex (i.e. right frontal operculum), while the fullness mindset caused reduced activation in the ventral striatum, an
\nimportant component of the reward system. Moreover, participants with overweight and obesity did not modify their
\nbehaviour under the pleasure mindset and selected larger portions than the normal-weight group.
\nConclusions We were able to identify specific brain response patterns as participants made a final choice of a portion size.
\nThe results demonstrate that different brain responses and behaviours during pre-meal planning can inform the development
\nof effective strategies for healthy weight management.<\/p>\n
