Hi Katie, great question!
Feel free to read the below to learn about food cravings.
1. The Psychology of Food Cravings: the Role of Food Deprivation – https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7399671/
2. Cravings – https://www.hsph.harvard.edu/nutritionsource/cravings/
Let me know if these answer your question, and I’ll continue to search for a book that might be suitable as well!
Warmth,
Riley
