Executive Function Hydration Before Meals
Executive function hydration before meals adds one water glass before autopilot breakfast and lunch—mild dehydration headaches often feel like hunger and impulse snacking on depleted days.
Executive function hydration before meals is a pre-meal water cue—one glass before autopilot breakfast and lunch—supporting mild dehydration headaches mistaken for hunger and impulse snacking. Cue stacks on existing meal anchors without new decisions.
Not gallon challenges; eight to twelve ounces per sitting. Especially useful on caffeine-heavy mornings and flight days.
Pair with visible bottle at desk. Does not replace food when truly underfed.
