The modern food environment is characterized by hyper-choice and routine dietary monotony, leading to food waste, nutritional imbalances, and reduced culinary adaptability. This paper introduces the concept of — a gamified, self-imposed dietary rule system derived from the Nuzlocke challenge in gaming. Under Foodlocke rules, an individual restricts their food choices based on stochastic or rule-based constraints (e.g., once a specific food item is consumed, it cannot be eaten again for a defined period or within a game-like "run"). This paper explores the behavioral, nutritional, and environmental implications of the Foodlocke framework. We argue that Foodlocke can serve as an intervention to increase dietary diversity, reduce over-reliance on preferred foods, and decrease household food waste. Preliminary theoretical models and potential experimental designs are proposed.
A 30-day Foodlocke run would require at least 90 unique food items (3 per day), far exceeding the average U.S. adult’s 20–30 unique items per month. Greater diversity is linked to lower all-cause mortality (Vadiveloo et al., 2015).
