To maintain high energy for her data science role, Penelope Lafoy strategically consumes most carbohydrates (rice, potatoes, fruit) before, during, or after workouts. This avoids glucose spikes during the workday, preventing the sluggishness that can derail focus and productivity.

The standard 5-gram dose of creatine is effective for muscle performance but insufficient to saturate the brain. To leverage creatine's neuroprotective and cognitive-enhancing effects—such as improved function when sleep-deprived or aging—a higher daily dose of 10 to 15 grams is necessary.

The standard 5g dose of creatine is largely absorbed by muscles, especially in active individuals. To achieve cognitive benefits like improved focus under stress, a higher dose of 10g or more is needed to create a "spillover" effect that saturates the brain with the compound.

Instead of using caffeine to wake up, delay intake for 2-3 hours. This allows natural adenosine to clear, creating more available receptors for caffeine to bind to later. This strategy transforms caffeine from a simple stimulant into a powerful tool for enhancing deep work and concentration.

High-stakes mental tasks are physically taxing; a top chess player can burn 600 calories sitting at a board. Physical conditioning is not just for athletes; it directly builds gray matter and enhances executive function, providing the stamina needed to make good decisions under cognitive stress in a professional environment.

The popular advice to drink massive amounts of water daily is evolutionarily inconsistent, as clean water was historically scarce. True hydration primarily comes from water-rich foods, not from constantly flushing your system, which can create mineral imbalances.

Reducing carbohydrates causes the body to excrete more water. This process flushes out essential electrolytes like sodium and potassium, making it necessary to consciously increase their intake to maintain proper fluid balance and physiological function.

Upon waking, your brain is full of cortisol and adrenaline, making caffeine ineffective. Wait 90 minutes for these natural stimulants to drop, then have coffee. This provides a bigger "bang for your buck" and allows time to rehydrate first after sleep's dehydrating effect.

To maintain stable energy for deep work, consume most carbohydrates (rice, potatoes, fruit) primarily before, during, or after workouts. This strategy allows the body to absorb the carbs effectively for fuel and recovery without causing the large glucose spikes that lead to sluggishness and napping during work sessions.
