How can one effectively ration food for survival in emergency situations?

To effectively ration food for survival in emergency situations, prioritize high-energy and nutrient-dense foods like canned goods, dried fruits, and nuts. Create a meal plan to ensure you're consuming enough calories each day. Portion out food to avoid overeating and conserve resources. Rotate through your food supply to prevent spoilage and maintain variety in your diet. Lastly, stay hydrated and consider foraging for additional food sources if possible.
