                                When a person eats very little, the body's metabolism can slow down as it enters 'conservation mode,' triggering a cascade of physical, metabolic, and psychological issues. A long-term pattern of undereating can lead to significant health complications, moving far beyond simple weight loss into a state of severe nutrient deprivation.
