Cognitive Fuel & Nootropics
The brain's output depends on its fuel supply, and small gaps in that supply show up first as fog, fatigue and forgetfulness.
This part of the Brain and Body library follows the chemistry, from blood sugar swings to creatine and omega three fats, grading each claim against peer reviewed evidence. The aim is to separate compounds that genuinely support cognition from those that merely promise to.

Glossary
Defined terms, each with its own entry.- AcetylcholineAcetylcholine drives attention, memory encoding, and muscle control. Learn its mechanism, clinical stakes in Alzheimer's disease, and how to support it.
- AutophagyAutophagy recycles damaged cellular components via lysosomes. Learn how fasting activates this pathway and what it means for longevity.
- GlucoseGlucose is the brain's primary fuel, supplying 20% of resting body energy from 2% of body mass. Blood sugar stability determines cognitive quality.
- Glycaemic IndexGlycaemic index (GI) ranks foods by their blood-glucose impact on a 0-100 scale. Low-GI diets lower fasting glucose and reduce cardiometabolic risk.
- GlycogenGlycogen: the body's carbohydrate reserve in liver, muscle, and brain. Definition, mechanism, and practical strategies to optimise stores for performance.
- Insulin ResistanceInsulin resistance is a metabolic state in which cells fail to respond normally to insulin, raising blood glucose, disease risk, and cognitive cost.
- Ketones (Beta-Hydroxybutyrate)Ketones are fat-derived molecules the liver produces during fasting. BHB fuels the brain, reduces oxidative stress, and modulates gene expression.
- KetosisKetosis is the metabolic state in which the liver converts fatty acids to ketone bodies. Covers definition, blood thresholds, and performance implications.
- Metabolic FlexibilityMetabolic flexibility is the capacity to switch between fat and glucose as fuel. It is impaired in insulin resistance and restored by aerobic exercise.
