Techniques are disclosed herein for generating personalized food guidance using predicted food hunger. Using the technologies described herein, instead of providing food guidance that is generalized for a group of individuals, personalized food guidance is provided that takes into account an individual's personalized responses to foods, including the predicted hunger of an individual. A nutritional service generates a hunger score that predicts a hunger level of an individual at a time (or for more than one time) after the individual has or is planning to consume food. The nutritional service uses the hunger score to generate the food guidance. Providing an individual with personalized food guidance can make choosing food easier and healthier.
