I disagree, there are other ways to damage your adrenals besides not eating. High Stress jobs, working out too hard, damaging your CNS etc. are all possible. "Adrenal fatigue" is just a term meaning damaged adrenals. Anorexia damages the adrenals and thus causes Adrenal fatigue. But not every case of adrenal fatigue is linked to starvation. Anorexia is linked to AF, but AF is not always linked to Anorexia
