Blaming the brain for obesity: integration of hedonic and homeostatic mechanisms

Abstract

The brain plays a key role in the controls of energy intake and expenditure, and many genes associated with obesity are expressed in the central nervous system. Technological and conceptual advances in both basic and clinical neurosciences have expanded the traditional view of homeostatic regulation of body weight by mainly the hypothalamus to include hedonic controls of appetite by cortical and subcortical brain areas processing external sensory information, reward, cognition, and executive functions. Hedonic controls interact with homeostatic controls to regulate body weight in a flexible and adaptive manner that takes environmental conditions into account. This new conceptual framework has several important implications for the treatment of obesity. Because much of this interactive neural processing is outside awareness, cognitive restraint in a world of plenty is made difficult and prevention and treatment of obesity should be more rationally directed to the complex and often redundant mechanisms underlying this interaction.

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

  • Weight-loss-induced appetite signals could cause subconscious biases such as gradually increasing portion sizes.

    “Thus, signals to the brain that increase appetite with weight loss could introduce subconscious biases such as portion sizes creeping upwards over time.”

    From Maintenance of Lost Weight and Long-Term Management of Obesity (2018) · cites this paper as [37]

    In “Set point theory” (page unavailable), the paper says that underfeeding prompts adaptive changes in food intake that return body weight toward its prior level. Its discussion of mindless eating says habitual intake can occur outside awareness. It does not connect weight-loss-induced appetite signals to portion sizes gradually increasing over time. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The perception of ongoing diet maintenance despite no further weight loss may occur because appetite regulation happens in brain regions below conscious awareness.

    “The patient’s perception of ongoing diet maintenance despite no further weight loss may arise because the physiological regulation of appetite occurs in brain regions that operate below the patient’s conscious awareness37.”

    From Maintenance of Lost Weight and Long-Term Management of Obesity (2018) · cites this paper as [37]

    The ‘Neural Control of Appetite and Food Intake’ section (page not provided) says much of the brain’s processing of food intake occurs outside awareness. The Conclusions (page not provided) similarly say homeostatic processes operate outside awareness and that weight loss cannot simply be willed. The paper does not address a patient’s perception of maintaining a diet despite a weight-loss plateau or establish that unconscious appetite regulation explains that perception. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Fat and carbohydrates, particularly sweet foods, are robust drivers of food choice and intake, with humans preferring and overconsuming sweet and/or fatty foods due to palatability, pleasure, and reward rather than specific defense of metabolic need.

    “Fat and carbohydrates, particularly sweet foods, are robust drivers of food choice and intake, with humans both preferring and overconsuming diets or foods that are sweet and/or fatty, not due to any specific defense of metabolic need, but instead due to palatability, pleasure, and reward”

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.
