When people don't eat for 3 days, their insulin levels drop significantly, which is part of the body's adaptation to fasting.
Scientific Claim
Acute starvation in healthy young adults is associated with a progressive decline in plasma insulin levels over 72 hours, reflecting reduced carbohydrate availability and metabolic adaptation to fasting.
Original Statement
“Plasma insulin fell progressively during starvation (Fig. 5; time effect P < 0.001, ANOVA).”
