As soon as possible after an event that even looks to be long term, the means to establish long term, sustainable, adequate food supplies should be implimented. Part of the pre-event planning should incorporate this.
If one waits until supplies are running low, it is probably too late to get enough food soon enough to prevent very drastic measures being necessary to get enough food to maintain adequate nutrition to prevent becoming incapacitated. (It takes a long time for a healthy adult to stave, if they have adequate water, but not very long to get to the point you can no longer do anything to help yourself.)
If the steps are not taken soon enough, and one does not, or cannot, get food even in less than admirable ways a d must institute severe rationing, it is going to be a very difficult decision on how to do it so everyone survives.
Because those that are capable of going out and getting more food are most likely going to be adult males and some adult females. That means they will need enough food to stay healthy enough to not only do that, but maintain their reasoning abilities so they will. So, unfortunately, the very people that most want to see get as much food as possible will be the ones getting just enough to keep them going.
The exception will be pregnant women and the women that are breast feeding newborns, and the babies. They must all get adequate nutritional food or risk serious permanent damage to the baby.
I know that many will not be able to cut the youngsters' rations to the degree necessary, and will wind up putting everyone at much higher risk. Because once adults can no longer function, the others are just not going to make it.
To me, this is the greatest incentive there is to not only store plenty of nutritious food, but have plans in place, and what is needed to produce good food in enough quantity soon enough to avoid any significant rationing of already somewhat limited meals. Besides, it is questionable if very many peppers will be able to produce LTS foods in much quantity very soon, so those LTS supplies obtained now might just have to be used at several different times.
Just my opinion.
