For what it is worth, I think a secure and clean water source is the first priority along with shelter from potentially very bad events in the near future.
Otherwise, you can purchase canned food, prep packs, or do some canning of your own. You can also hunt and fish (learning those skills may be very, very important depending on where you live). I would assume at least 1,500 calories per day per person. So, I would estimate about 550,000 calories per person.
Getting in good shape is something that I would advise to everyone, and learn what skills you can along with your local geography.
A rain water collection system feeding into a mostly buried and tarped 1k litre IBC makes for a decent supply of water depending on where you live. It'll still need to be filtered but that's easy enough to set up with a decent pump, tubing and charcoal, ceramic and uv filters.
