Treating Metabolic Dysregulation and Senescence by Caloric Restriction: Killing Two Birds with One Stone?
Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing mechanistic concepts without primary human data.
PubMed 39857433 · doi:10.3390/antiox14010099
What was done
Narrative review synthesizing the mechanistic pathways linking overnutrition, cellular senescence, and endothelial-adipocyte crosstalk, focusing on the potential of caloric restriction to modulate nutrient-sensing cascades including insulin/IGF-1 signaling, mTOR, AMPK, and sirtuins.
What was found
No quantitative data or empirical metrics are reported in the abstract. The review describes how overnutrition and senescence disrupt autophagy, increase oxidative stress, and impair endothelial-adipose signaling, whereas caloric restriction counteracts these processes to restore mitochondrial function and metabolic balance.
Why it matters
Synthesizes mechanistic links between adipose tissue and vascular dysfunction, presenting caloric restriction as a dual intervention against metabolic disease and age-related cellular senescence.
Limits
Narrative review without original human experimental data or systematic study selection methodology. The abstract provides no specific caloric restriction protocols, quantitative effect sizes, or clinical outcome measurements.
