Metabolic Adaptation

Survival mode. Your metabolism slows because it thinks you are starving.

Definition

The body’s “survival” mode. Your metabolism slows down because it thinks you’re starving.

Why it matters

Decades of yo-yo dieting make this worse, and it is one of the real reasons a GLP-1 can underperform. Your body is not broken. It is very good at survival.
