When animals are given access to a variety of highly palatable foods rather than standard chow, they massively overeat and rapidly become obese. Research by Sclafani and Rolls documented how variety and palatability drive overconsumption independent of caloric need. The modern food environment is a giant cafeteria diet experiment—endless variety, engineered palatability, and predictable results.
This companion explores the original cafeteria experiments, why variety drives overconsumption (sensory-specific satiety), why palatability overrides satiety, the modern cafeteria parallels, and practical implications for simplifying your food environment. (4 min read)
