When your body is under long-term stress, it releases a hormone called cortisol that breaks down muscle and ramps up blood sugar in a way that together makes your metabolism worse over time.

Assessment Explanation
The claim asserts a synergistic, causal pathway leading to progressive decline, which implies a deterministic mechanism. However, while cortisol's individual catabolic effects on protein (e.g., muscle breakdown) and glucose (e.g., gluconeogenesis) are well-documented, evidence for a tightly coupled, synergistic pathway driving progressive metabolic decline is not conclusively established. Human studies show associations in chronic stress or Cushing’s syndrome, but confounding factors (e.g., insulin resistance, inflammation, diet) make it difficult to isolate cortisol as the sole driver. The term 'synergistic pathway' and 'progressive decline' suggest a linear, inevitable outcome not fully supported by current evidence.
More Accurate Statement
“Cortisol's catabolic actions on protein breakdown and glucose production may interact in ways that contribute to, or exacerbate, metabolic dysfunction over time in conditions of chronic stress or hypercortisolism.”

When you're stressed for a long time, your body makes too much cortisol, which breaks down muscle and messes up blood sugar — and these two problems feed off each other, making your metabolism worse over time. This study says that’s exactly what happens.
