I read some Russian articles about research carried out about 40 years ago about the most efficient way to survive on limited food if one gets lost in wild nature. Their conclusion was that one should not ration food. One should just eat normally until one runs out of food and then fast until normal amount of food is available. And fast here means literally zero calories. One should not eat berries, mushrooms etc. Those triggers digestion that spend more energy that will be extracted from snacks.
