When consumed in large amounts, sugar can prevent the normal habituation of dopamine response, so continued high dopamine release sustains reward and incentive to keep consuming similarly to addictive drugs.

Water can serve as a thermal interface but is worse for sautéing because it boils at 212°F (100°C) and escapes as steam before reaching the ~330°F needed for Maillard browning, and its low viscosity prevents it from coating food effectively.

Repeated or excessive stimulation of reward pathways causes neuroadaptive changes that weaken regulation and increase craving and tolerance, so the behavior persists despite negative consequences.

Dopamine produces stronger motivational effects in brain 'hotspots' because dopamine receptors are unevenly clustered across forebrain regions, so release in dense receptor areas is amplified and more strongly drives behavior.

A thin film of oil acts as a thermal interface because it fills gaps between an uneven food surface and a flat pan, contacting bits that metal alone misses and conducting heat into more of the food.

Proteins stick to hot metal because they denature at high temperature and can form chemical bonds or complexes with the metal surface, anchoring the protein until enough browning and rigidity allows release.

The brain's reward network generates a subconscious "should I do that again?" signal because interconnected electrical and chemical pathways translate pleasurable inputs into motivation, linking positive feeling to future-directed behavior.

Non-stick pans reduce adhesion but can worsen uneven cooking because steam bubbles can lift food away from the surface, interrupting sustained contact and producing gray, underbrowned patches instead of a continuous crust.

Fat prevents sticking both by physically separating proteins from the pan and by acting as an effective thermal interface that cooks the surface faster so a brown crust forms and lifts more easily.

Cooking without oil produces highly localized browning and much slower overall cooking because only the tiny points touching the metal get efficient heat transfer, so those spots can burn while most of the food stays cooler.

Non-taste sugar receptors in the gut send signals to the brain that indicate fullness and trigger insulin production, so intestinal detection links directly to appetite control and hormonal responses to sugar.

Fattier cuts or skin-on pieces can self-baste because rendered fat melts and collects in the pan, coating surfaces so the meat effectively fries in its own fat as cooking proceeds.

Oiling before oven roasting often matters less because convective oven heat and the food's own rendered fat can redistribute over surfaces and promote browning without the direct, localized contact dynamics of a hot pan.

Sweet-taste receptors on the tongue send signals to the brainstem, which branch into forebrain areas including the cerebral cortex, so the sensory detection of sugar is transmitted upward into higher taste-processing regions.

Different sugar molecules all initiate the same chain of sensory detection and neural signaling that activates reward pathways, so chemically distinct sugars nonetheless produce a similar pleasurable response.

Dietary fats are important because they dissolve and transport fat‑soluble vitamins (A, D, E, K), enabling those nutrients to be absorbed in the intestines.
