Abstract

Obesity is a worldwide epidemic resulting in part from the ubiquity of high-calorie foods and food images. Whether obese and nonobese individuals regulate their desire to consume high-calorie foods differently is not clear. We set out to investigate the hypothesis that circulating levels of glucose, the primary fuel source for the brain, influence brain regions that regulate the motivation to consume high-calorie foods. Using functional MRI (fMRI) combined with a stepped hyperinsulinemic euglycemic-hypoglycemic clamp and behavioral measures of interest in food, we have shown here that mild hypoglycemia preferentially activates limbic-striatal brain regions in response to food cues to produce a greater desire for high-calorie foods. In contrast, euglycemia preferentially activated the medial prefrontal cortex and resulted in less interest in food stimuli. Indeed, higher circulating glucose levels predicted greater medial prefrontal cortex activation, and this response was absent in obese subjects. These findings demonstrate that circulating glucose modulates neural stimulatory and inhibitory control over food motivation and suggest that this glucose-linked restraining influence is lost in obesity. Strategies that temper postprandial reductions in glucose levels might reduce the risk of overeating, particularly in environments inundated with visual cues of high-calorie foods.

  • Simultaneously, hunger and cravings for high-GL foods increase, setting the stage for a vicious cycle.

    “Simultaneously, hunger and cravings for high-GL foods (i.e., those that rapidly raise blood glucose) increase, setting the stage for a vicious cycle.”
  • Experimentally reducing blood glucose to mild hypoglycemic levels relative to normal euglycemic levels increases plasma cortisol and increases wanting of highly palatable foods and brain activation of reward-motivational and emotion-stress regions in response to high-fat, high-sugar highly palatable versus low-fat and non-food pictures.

    “experimentally reducing blood glucose to mild hypoglycemic levels relative to normal euglycemic levels, not only increases plasma cortisol but also increases wanting of HP foods and brain activation of reward-motivational (striatal) and emotion-stress (limbic) regions in response to high fat, high sugar HP versus low fat and non-food pictures”

  • Higher cortisol responses in the hypoglycemic state were associated with higher striatal-limbic brain activation during concurrent assessment.

    “higher cortisol responses in the hypoglycemic state was associated with higher striatal-limbic brain activation during concurrent assessment of these responses”

  • The decline in blood glucose (and other metabolic fuels) in the late postprandial period after a high-GI meal increases the hedonic value of food through striatal activation.

    “but also increase the hedonic value of food through striatal activation (18).”
  • In a study of lean and obese adults, a mean insulin-induced decrease in blood glucose concentrations from 4.9 to 3.7 mmol/L increased the food-stimulus activation of the striatum and desire for high-calorie foods.

    “Indeed, in a study of lean and obese adults, a mean insulininduced decrease in blood glucose concentrations from 4.9 to 3.7 mmol/L increased the food-stimulus activation of the striatum and desire for high-calorie foods (18).”

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.
