Abstract

Consumption of a low-protein, high-carbohydrate diet induces a striking increase in circulating fibroblast growth factor-21 (FGF21), which is associated with improved cardiometabolic health and increased longevity. Increased lifespan during this dietary protein "dilution" has been explained by resource-mediated trade-offs between reproduction and survival, such that fecundity is optimized at a greater relative intake of proteins/carbohydrates. The magnitude of this trade-off is thought to be sex-dependent. In this study, we tested the hypothesis that metabolic responses to dietary protein dilution are likewise dependent on sex. We maintained age-matched adult male and female C57BL/6J mice on isocaloric diets containing 22% fat and differing in the ratio of protein/carbohydrate. The normal protein (NP) control diet contained 18% protein and 60% carbohydrate by kcal. The protein diluted (PD) diet contained 4% protein and 74% carbohydrate. Consistent with previous reports, PD males gained less weight and less fat than did normal protein controls and exhibited both improved glucose tolerance and decreased plasma lipids. In contrast, these metabolic benefits were absent among age-matched females maintained on the same diets. Likewise, whereas circulating FGF21 was increased up to 66-fold among PD male mice, this was substantially blunted among female counterparts. Sex differences in energy balance, glucose control, and plasma FGF21 were reversed upon ovariectomy. Collectively, our findings support that female mice are relatively less sensitive to the metabolic improvements observed following dietary protein dilution. This is accompanied by blunted circulating levels of FGF21 and requires an intact female reproductive system.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Liver FGF21 expression and circulating FGF21 protein levels are increased by the restriction of protein intake in mice, rats, and humans.

    “liver FGF21 expression and circulating FGF21 protein levels are increased by the restriction of protein intake in mice, rats, and humans”
  • Reductions in dietary protein intake-or the intake of specific amino acids-increase liver FGF21 mRNA expression and circulating FGF21 protein levels.

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.
