Abstract

Background Calorie restriction (CR) is accepted as an experimental anti-aging paradigm. Several important signal transduction pathways including AMPK and SIRT1 are implicated in the regulation of physiological processes of CR. However, the mechanisms responsible for adaptations remain unclear in humans.Scope of review Four overweight male participants were enrolled and treated with 25% CR of their baseline energy requirements for 7weeks. Characteristics, including body weight (BW), body mass index (BMI), %fat, visceral fat area (VFA), mean blood pressure (MBP) and VO2 max, as well as metabolic parameters, such as insulin, lipid profiles and inflammatory makers and the expression of phosphorylated AMPK and SIRT1 in peripheral blood mononuclear cells (PBMNCs), were determined at baseline and then after 7weeks. In addition, we assessed the effects of the serum collected from the participants on AMPK and SIRT1 activation and mitochondrial biogenesis in cultured human skeletal muscle cells.Major conclusions After CR, BW, BMI, %fat, VFA and MBP all significantly decreased, while VO2 max increased, compared to those at baseline. The levels of fasting insulin, free fatty acid, and inflammatory makers, such as interleukin-6 and visfatin, were significantly reduced, whereas the expression of phosphorylated AMPK and SIRT1 was significantly increased in PBMNCs collected after CR, compared to those at baseline. The skeletal muscle cells that were cultured in serum collected after CR showed an increase in AMPK and SIRT1 activity as well as mitochondrial biogenesis.General significance CR is beneficial for obesity-related metabolic alterations and induces cellular adaptations against aging, possibly through AMPK and SIRT1 activation via circulating factors.

  • Caloric restriction is effective in ameliorating obesity-related metabolic impairments and increasing mitochondrial biogenesis markers, primarily through metabolic pathways involving AMPK and SIRT1.

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.
