Metabolic Flexibility & Glucose Stability Test

Completely unaffected; calm, sharp mind, body easily burns stored fat. I feel mild hunger, but no mood swings or panic. I get irritable, shaky ("hangry"), and struggle to concentrate. Severe dizziness, cold sweats, and overwhelming urgency to consume starch.

Light, energized, and ready for mental work or a brisk walk. Satisfied and comfortable with steady alertness. Heavy, lethargic, with an irresistible urge to lie down or nap. Brain fogged, bloated, and craving more sugar 1 hour later.

Easily; fasted walks are my favorite way to boost mental clarity. Yes, with a glass of water or herbal tea. I feel weak and dizzy unless I eat carbohydrates first. Impossible; cannot step out of bed without food.

Waist is comfortably under 45-50% of my total height (minimal visceral fat). Right around 50% of height. Carrying noticeable central abdominal fat while arms/legs are thinner. Significant visceral belly expansion (>60% of height).
