The Claim
A three-day water-only fast alters plasma proteomic and metabolomic profiles in healthy adults, including changes in proteins and metabolites linked to inflammation, oxidative stress, and cellular stress response pathways.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A three-day water-only fast changes the levels of proteins and metabolites in the blood of healthy adults, specifically those involved in inflammation, oxidative stress, and cellular stress response pathways.
See the scientific wording
A three-day water-only fast alters plasma proteomic and metabolomic profiles in healthy adults, including changes in proteins and metabolites linked to inflammation, oxidative stress, and cellular stress response pathways.
When a person stops eating for three days, the body runs out of sugar stores and starts burning fat for energy. This produces ketones, which lower insulin and IGF-1 levels. Lower IGF-1 turns off a cellular growth signal called mTOR, which triggers the cleanup of damaged cell parts through autophagy. At the same time, ketones reduce oxidative stress and block inflammatory pathways, changing the proteins and chemicals in the blood to reflect a shift from growth to repair.
What the research says
1 studyAfter three days without food, the body changes its blood chemicals in ways that help clean up damaged cells and reduce inflammation—like turning on a repair mode. This study shows those exact changes happened.
