How much someone likes a food is a stronger driver of their craving and motivated behavior toward it than how long they’ve gone without eating it.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether hedonic preference (liking) consistently outweighs abstinence duration as a predictor of craving and motivated behavior across food types, populations, and measurement methods.
A systematic review and meta-analysis of all studies measuring liking, craving, and instrumental behavior in response to palatable foods, with standardized effect size comparisons between liking and abstinence duration predictors.
Whether experimentally increasing liking for a neutral food (e.g., via repeated exposure) increases craving and instrumental behavior more than extending abstinence from a highly liked food.
A double-blind RCT with 100 adults randomized to either 10 days of repeated exposure to a neutral food (increasing liking) or 10 days of abstinence from a highly liked food; craving and button presses measured before and after, with fMRI to assess reward circuit activation.
Whether individuals with higher baseline food liking show greater increases in craving and behavior during abstinence compared to those with lower liking.
A 6-month prospective cohort study of 400 adults measuring baseline liking for 10 foods, then tracking craving and food-memory behaviors during natural abstinence periods, controlling for BMI and dietary restraint.
The relative predictive power of liking versus time since last consumption for craving and instrumental behavior in a general population.
A cross-sectional survey of 6,000 adults measuring liking (0–100), time since last consumption, craving (0–100), and frequency of food-memory behaviors for top 3 favorite foods, with multivariate regression comparing effect sizes.
Individual cases where high liking does not predict craving or behavior, or where low liking does despite abstinence.
Detailed case series of 5 individuals with unusual food preferences (e.g., food aversions, orthorexia) documenting craving and behavior despite abstinence or high liking.
