Abstract

Protein-restricted (PR), high-carbohydrate diets improve metabolic health in rodents, yet the precise dietary components that are responsible for these effects have not been identified. Furthermore, the applicability of these studies to humans is unclear. Here, we demonstrate in a randomized controlled trial that a moderate PR diet also improves markers of metabolic health in humans. Intriguingly, we find that feeding mice a diet specifically reduced in branched-chain amino acids (BCAAs) is sufficient to improve glucose tolerance and body composition equivalently to a PR diet via metabolically distinct pathways. Our results highlight a critical role for dietary quality at the level of amino acids in the maintenance of metabolic health and suggest that diets specifically reduced in BCAAs, or pharmacological interventions in this pathway, may offer a translatable way to achieve many of the metabolic benefits of a PR diet.

  • In another randomized clinical trial, feeding customized, isocaloric, moderately protein-restricted diets for 4-6 weeks to middle-aged overweight and mildly obese men resulted in a significant decrease in body weight, fat mass, and fasting blood glucose levels, and a major increase in circulating FGF21 concentration.

    “In contrast, in another randomized clinical trial, feeding customized, isocaloric, moderately protein-restricted diets for 4–6 weeks to middle-aged overweight and mildly obese men resulted in a significant decrease in body weight, fat mass, and fasting blood glucose levels, and a major increase in circulating FGF21 concentration (79).”
  • Selectively reducing dietary intake of branched-chain amino acids significantly improves glucose tolerance, β cell metabolic stress, and body composition in a recent rodent study.

    “In contrast, data from a recent rodent study show that selectively reducing the dietary intake of branched-chain amino acids significantly improves glucose tolerance, β cell metabolic stress, and body composition (79).”
  • FGF21 is also increased by the restriction of individual amino acids.

    “with FGF21 also being increased by the restriction of individual amino acids”

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.
