The Claim
Intermittent fasting increases red blood cell distribution width (RDW-CV) in male and female mice across multiple strains, indicating an elevation in erythropoietic stress.
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.
Intermittent fasting raises red blood cell distribution width in male and female mice of multiple strains, which reflects increased variability in red blood cell size due to altered red blood cell production.
See the scientific wording
Intermittent fasting increases red blood cell distribution width (RDW-CV), a marker of erythropoietic stress, in both male and female mice across multiple strains, suggesting a consistent physiological stress response to fasting that may reflect micronutrient deficiency or altered red blood cell production.
When food is skipped regularly, the body gets less iron and other nutrients needed to make healthy red blood cells. This causes some red blood cells to form poorly and become uneven in size, which shows up as higher variation in red blood cell size.
What the research says
1 studyStudy: Genetic regulation of fasting-induced longevity effects
In mice, skipping food every other day made their red blood cells more uneven in size — a sign their bodies were under stress making blood. This happened in every type of mouse tested, no matter if they were male or female.
