Meal Kit Supply recommends the consumption of 1-2 MREs per person per day (between ~1,200 and ~2500 calories per day). This means a Meal Kit Supply case of 12 MREs would provide a full 6 days supply of food for 1 person. Alternatively, 1 case would feed 4 people well for 2 days. A basic emergency preparedness kit should contain 1 case of MREs and 1 case of bottled water to ensure 1 week of nourishment for 1 individual.
