The Glucose Rollercoaster#

Carb-heavy lunches (pizza, sandwiches, pasta) cause a rapid spike in blood sugar. Insulin rushes in to manage it, causing a crash 90 minutes later. The Solution: Flatten the curve.

Hack 1: Savory Breakfasts#

Start the day with protein and fats, not sugar.

Swap: Cereal/Pastry -> Eggs/Avocado/Greek Yogurt.
Why: Sets a stable baseline for the day.

Hack 2: Order of Operations#

Eat food in the right order to reduce glucose impact:

Variables (Fiber) first.
Proteins/Fats second.
Carbs/Starches last.

Hack 3: Hydration != Coffee#

Caffeine blocks adenosine (sleep pressure), but it doesn't hydrate you. Being 1% dehydrated drops cognitive function by 5%.

Rule: 1 glass of water for every cup of coffee.

Conclusion#

Your brain consumes 20% of your body's energy. Feed it premium fuel, and you'll get premium performance.
