Hunger
Biological response to replenish energy reserves (Instinctively protects us from starvation) Triggers considered “Below the neckline”- low blood sugar, growling stomach, hormone fluctuations, need to warm the body (hypothermia)…appears several hours w/o food, diminishes after eating, satisfied by any food generally.
Appetite
Desire or interest to eat a specific food. More rapid onset that is independent of hunger. Triggers considered “Above the neckline” - conscious/subconscious- emotions, social aspects, thoughts, hormones, culture…NOT time dependent, may persist after eating, satisfied by specific foods that evoke emotions afterwards. (sweet, savory, etc.)

16 - 24 oz. 2 hours before activity
8 - 16 oz. 30 min before (hot, humid, days)
Fluid intake during sports

60 min = 4-8% carbohydrate solution w/ electorlytes
Fluid intake post sports
