Food Cravings

Food cravings are intense desires for specific foods, often high in sugar, fat, or salt. Unlike true hunger — which builds gradually and can be satisfied by any food — cravings come on suddenly and feel urgent. They are driven by brain chemistry, emotions, and habits, not by your body’s actual need for energy.

Food cravings are selective, intense urges to consume specific palatable foods, mediated by dopaminergic reward pathways in the mesolimbic system. They are distinct from physiological hunger and are influenced by neuroendocrine factors (ghrelin, leptin, cortisol), conditioned cues, emotional states, and hedonic responses to hyperpalatable foods. Chronic cravings are associated with reduced dopamine D2 receptor availability, similar to patterns seen in addiction.

Understanding the difference between cravings and hunger is a cornerstone of behavioural weight management. At Accord Medical, Dr Joseph Wang helps patients identify craving triggers and develop strategies — including structured meal timing, GLP-1 medications that dampen reward-driven eating, and mindful eating techniques — to regain control over food choices.
