Abstract

Reduced dietary protein intake induces adaptive physiological changes in macronutrient preference, energy expenditure, growth, and glucose homeostasis. We demonstrate that deletion of the FGF21 co-receptor βKlotho (Klb) from the brain produces mice that are unable to mount a physiological response to protein restriction, an effect that is replicated by whole-body deletion of FGF21. Mice forced to consume a low-protein diet exhibit reduced growth, increased energy expenditure, and a resistance to diet-induced obesity, but the loss of FGF21 signaling in the brain completely abrogates that response. When given access to a higher protein alternative, protein-restricted mice exhibit a shift toward protein-containing foods, and central FGF21 signaling is essential for that response. FGF21 is an endocrine signal linking the liver and brain, which regulates adaptive, homeostatic changes in metabolism and feeding behavior during protein restriction.

  • Effects of extended FGF21 signalling in promoting weight loss through increased energy expenditure are mediated through direct actions on the CNS, not adipose tissues.

    “These effects of extended FGF21 signalling in promoting weight loss through increased energy expenditure are mediated through direct actions on the central nervous system67,80–84, not adipose tissues65,67,85”

  • FGF21 signalling to the CNS is required for the weight loss associated with a low-protein diet.

    “In addition, as expected according to the mechanism of FGF21’s action in increasing energy expenditure, FGF21 signalling to the CNS is required for the weight loss associated with a low-protein diet83,84.”

    From Metabolic messengers: FGF21 (2021) · cites this paper as [83]

  • Maximal circulating FGF21 levels increase in response to a combination of low-protein and high-carbohydrate conditions.

    “maximal levels of circulating FGF21 increase in response to a combination of low-protein and high-carbohydrate conditions [152,158,165].”
  • Control mice adaptively shift macronutrient preference and increase protein intake in response to dietary protein restriction.

    “while control mice adaptively shift macronutrient preference and increase protein intake in response to dietary protein restriction”
  • Mice that lack either FGF21 or FGF21 signaling in the brain fail to exhibit the adaptive increase in protein intake in response to dietary protein restriction.

    “mice that lack either FGF21 or FGF21 signaling in the brain fail to exhibit this homeostatic response”

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.
