Abstract

Objective: Physical activity (PA) promotes weight maintenance, potentially because of its beneficial effects on feeding behavior regulation via diminished food cue reactivity within brain reward regions. This study examined how levels of PA and sedentary behavior (SB) relate to brain responses to food cues. Methods: Participants (22 lean, 18 with obesity) completed three to five PA recalls over 2 months. Average minutes per day of moderate to vigorous PA (MVPA) and SB were calculated. Participants completed a functional magnetic resonance imaging session, viewing food and nonfood images following glucose ingestion. Region of interest (ROI) analysis examined associations between MVPA and brain percent signal change in response to food versus nonfood images, controlling for obesity and sex. Secondary analysis examined associations between SB and brain responses to food cues. Results: Greater MVPA was associated with decreased food cue reactivity after glucose across brain ROIs (β = −0.00057, P = 0.005), controlling for obesity and sex. Greater SB was associated with increased food cue reactivity after glucose across brain ROIs in unadjusted analyses (β = 0.00041, P = 0.026). Conclusions: PA may have beneficial effects on brain regulation of feeding behavior after caloric intake in lean individuals and individuals with obesity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Transient factors and states such as time of day, surrounding environment, sleep duration, psychological stress, emotional state, physical activity, and appetite-regulating hormones are associated with varying levels of food cue reactivity.

    “Similarly, transient factors and states, such as the time of day, surrounding environment, sleep duration, level of psychological stress, emotional state, physical activity, and levels of appetite-regulating hormones (e.g., circulating levels of leptin, ghrelin, PYY, endogenous GLP-1, and GLP-1RAs), have been associated with varying levels of food cue reactivity [46,51,52,53,54,55,56,57,58,59,60,”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
