Short Plant-Based Fast Triggers Gene Shifts and Fat Beiging, Study Finds
A Nature Communications study of about 200 Orthodox Christians who regularly fast from meat and dairy, plus a non-fasting control group, shows that short-term animal-product restriction can alter gene expression and metabolic markers—including FGF21—with signs of adipose tissue beiging and a genotype-linked change in the LBR gene, highlighting a complex diet–genetics relationship and the need for further research.
