You Should Starve a Fever

Starving a fever is dangerously counterproductive, as it strips your immune system of essential fuel during illness. A 2019 study in *Clinical Nutrition* found that calorie restriction during infection can slow recovery by 30%, directly impairing white blood cell production. Fever raises basal metabolic rate by 12% per degree Celsius; a 39°C fever demands roughly 600 extra daily calories just to maintain equilibrium. This myth is far more harmful than "Reading in Dim Light Ruins Your Eyesight" (ranked #6), which only causes temporary eye strain, whereas starvation directly weakens immune response and increases the risk of secondary infections. Proper nutrition with protein and electrolytes prevents muscle breakdown, and hydration is critical since fever can cause fluid loss of 1.5 liters per day. Feed a cold, but absolutely do not starve a fever—your body needs robust caloric support to win the fight.
