Sixty studies were identified that investigated the neural responses of healthy weight participants (n = 26), healthy weight compared to obese participants (n = 17), and weight-loss interventions (n = 12). High-calorie food images were used in the majority of studies (n = 36), however, image selection justification was only provided in 19 studies. Obese individuals had increased activation of reward-related brain areas including the insula and orbitofrontal cortex in response to visual food cues compared to healthy weight individuals, and this was particularly evident in response to energy dense cues. Additionally, obese individuals were more responsive to food images when satiated. Meta-analysis of changes in neural activation post-weight loss revealed small areas of convergence across studies in brain areas related to emotion, memory, and learning, including the cingulate gyrus, lentiform nucleus, and precuneus. Differential activation patterns to visual food cues were observed between obese, healthy weight, and weight-loss populations. Future studies require standardization of nutrition variables and fMRI outcomes to enable more direct comparisons between studies.]]> Wed 11 Apr 2018 10:57:34 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:1388 Sat 24 Mar 2018 08:28:01 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45696 Fri 04 Nov 2022 08:20:57 AEDT ]]>
