When training for a mental sport like chess, the foundational step is stabilizing energy by managing glucose metabolism, perhaps via intermittent fasting. Many athletes jump to "smart drugs" and stimulants, but this is ineffective if the underlying energy system is volatile and prone to crashes.

As we age, the timing of calorie consumption becomes more critical than the quantity. One calorie consumed after 6 PM can have the metabolic impact of ten calories consumed before noon due to its effect on insulin production during sleep. This highlights the importance of front-loading caloric intake.

To encourage better choices, emphasize immediate, tangible rewards over long-term, abstract goals. A Stanford study found diners chose more vegetables when labeled with delicious descriptions ("sizzling Szechuan green beans") versus health-focused ones ("nutritious green beans"). This works with the brain's value system, which prioritizes immediate gratification.

The "carbs vs. fat" diet war is a distraction. The body adapts to its fuel source, and on a caloric basis, excess energy from either carbohydrates or fats is stored as body fat to the same degree. Cutting calories from either source leads to similar weight loss.

Instead of medicating or ignoring symptoms like fatigue or mood swings, view them as your body's way of signaling an underlying issue. By treating symptoms as messages, you can focus on the root cause (like glucose spikes), which makes the 'messages' disappear.

Eating sugar on an empty stomach causes a rapid glucose spike. Consuming the same sweet treat after a meal containing fiber, protein, and fat slows the glucose absorption, significantly reducing the spike and preventing the subsequent craving roller coaster.

Instead of chasing weight loss, focus on foundational health markers like inflammation, blood sugar balance, stress levels, and nutrient deficiencies. When these systems are optimized, sustainable weight loss and body recomposition often occur as a natural side effect.

Starting a meal with vegetables allows their fiber to coat the upper intestine, creating a protective mesh. This slows down the absorption of glucose from starches and sugars consumed later in the meal, dramatically reducing the subsequent blood sugar spike.

The crash following a glucose spike activates the brain's craving center. This is a physiological command, not a lack of willpower. Stabilizing glucose levels eliminates the biological trigger for intense cravings, making them naturally disappear.
