Obesity: the protein leverage hypothesis

Simpson, S. J., Raubenheimer, D.·2005·Obesity Reviews

Abstract

Summary: The obesity epidemic is among the greatest public health challenges facing the modern world. Regarding dietary causes, most emphasis has been on changing patterns of fat and carbohydrate consumption. In contrast, the role of protein has largely been ignored, because (i) it typically comprises only ∼15% of dietary energy, and (ii) protein intake has remained near constant within and across populations throughout the development of the obesity epidemic. We show that, paradoxically, these are precisely the two conditions that potentially provide protein with the leverage both to drive the obesity epidemic through its effects on food intake, and perhaps to assuage it. We formalize this hypothesis in a mathematical model. Some supporting epidemiological, experimental and animal data are presented, and predictions are made for future testing.

Claims other papers make about this one

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

  • The protein leverage hypothesis could partially explain the higher energy intake observed with the ultra-processed diet.

    “suggests that the protein leverage hypothesis could partially explain the increase in energy intake with the ultra-processed diet”
  • During amino acid restriction, mammals increase their consumption of diets low in protein to acquire sufficient protein to satisfy organismal requirements, despite increasing their overall caloric intake.

    “During amino acid restriction, mammals increase their consumption of diets low in protein to acquire sufficient protein to satisfy organismal requirements, despite increasing their overall caloric intake125–129.”

    From Metabolic messengers: FGF21 (2021) · cites this paper as [125]

  • Protein is prioritized and regulated to a specific target, so small changes in the proportion of dietary protein can induce large changes in total food and energy intake (protein leveraging).

    “The observation that protein is prioritized and regulated to a specific target suggests that small changes in the proportion of dietary protein can induce large changes in total food and energy intake, a concept termed protein leveraging”

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.
