Why Caloric Planning Matters

Your body needs a baseline number of calories to perform essential functions like breathing, thinking, and moving. Add survival scenarios, physical exertion, or extreme weather, and those caloric needs skyrocket. Underestimating could leave you undernourished when it matters most.

Plan for Your Family’s Unique Needs

Daily Requirements: Know how many calories each person in your family needs for regular activity.
Activity Adjustments: Factor in higher demands for physically intense scenarios like hiking or hauling supplies.
Long-Term Readiness: Create food stores tailored to your family’s specific caloric requirements, ensuring no one is left underfed.
