Food Rationing Calculator & Strategies
Series: 90-Day Survival Guide Sprint - Guide #2
Category: Food Storage & Rationing
Difficulty: Beginner
When This Matters
Food security becomes critical during:
- Natural disasters (hurricanes, earthquakes)
- Supply chain disruptions (pandemics, fuel shortages)
- Economic collapse (hyperinflation, bank runs)
- Civil unrest (looting, store closures)
- Extended power outages
- Job loss/income disruption
Reality: Most households have 3-7 days of food. Experts recommend 2 weeks minimum, 3 months ideal.
Understanding Caloric Needs
Quick Reference Table
| Person | Weight | Age | Daily Calories |
|---|---|---|---|
| Adult Male (average) | 195 lbs | 40 | ~2,500 |
| Adult Female (average) | 165 lbs | 40 | ~2,000 |
| Teen (15) | 150 lbs | 15 | ~2,400 |
| Child (10) | 70 lbs | 10 | ~1,800 |
| Elderly (70) | 150 lbs | 70 | ~1,600 |
Activity Multipliers
| Activity Level | Multiplier | Description |
|---|---|---|
| Sedentary | 1.2 | Sheltering in place |
| Light | 1.375 | Basic chores |
| Moderate | 1.55 | Physical labor, gardening |
| Active | 1.725 | Heavy labor |
| Very Active | 1.9 | Survival situations |
Crisis Rationing Tiers
| Tier | Calories/Day | Duration | Effects |
|---|---|---|---|
| Normal | 100% | Indefinite | Full energy |
| Reduced | 75% | 2-4 weeks | Mild fatigue |
| Survival | 50% | 4-8 weeks | Weight loss |
| Emergency | 1,200-1,500 | 2-4 weeks max | Bare minimum |
Important: Never severely ration children, pregnant/nursing women, elderly, or ill individuals.
Building Your Food Storage
Phase 1: Two-Week Supply (Start Here)
Family of 4 Checklist:
| Category | Quantity | Examples |
|---|---|---|
| Water | 112 gallons | Bottled, filtered |
| Grains | 28 lbs | Rice, pasta, oats |
| Protein | 14 lbs canned | Tuna, chicken, beans |
| Vegetables | 28 cans | Mixed veggies, tomatoes |
| Fruits | 14 cans | Peaches, pears |
| Comfort | 14 items | Coffee, tea, snacks |
| Cooking | As needed | Oil, spices, sugar |
Budget Strategy: Buy 2-3 extra items each grocery trip. Full supply in 2-3 months.
Phase 2: Three-Month Supply
| Food | Quantity | Storage |
|---|---|---|
| Rice (white) | 50 lbs | Bucket + O2 absorber |
| Beans (dry) | 35 lbs | Bucket + O2 absorber |
| Pasta | 30 lbs | Original packaging |
| Oats | 15 lbs | Bucket |
| Canned Meat | 30 cans | Pantry |
| Canned Vegetables | 45 cans | Pantry |
| Canned Fruit | 24 cans | Pantry |
| Cooking Oil | 6 bottles (48 oz) | Cool, dark |
| Sugar/Honey | 15 lbs + 5 lbs | Airtight |
| Salt | 5 lbs | Airtight |
| Multivitamins | 3 bottles | Cool, dry |
Provides ~1,400 calories/person/day (survival ration).
Food Rotation System
FIFO Method (First In, First Out)
- New items go in BACK
- Old items come from FRONT
- Check dates monthly
- Use oldest first
Storage Timeline
| Food Type | Shelf Life | Rotation |
|---|---|---|
| White rice | 25-30 years | Every 5 years |
| Dried beans | 10+ years | Every 3 years |
| Pasta | 5-10 years | Every 2 years |
| Canned goods | 2-5 years | Every 1-2 years |
| Cooking oil | 1-2 years | Every 6 months |
| Flour (white) | 5-8 years | Every 2 years |
| Honey | Indefinite | Never |
| Salt | Indefinite | Never |
Rationing Strategies
When to Start Rationing
- Day 1-3: Normal portions, assess situation
- Day 4-7: Reduce portions 10-15%, eliminate waste
- Week 2+: Implement tiered rationing based on supply
Portion Control Tips
- Use smaller plates - psychological trick
- Pre-portion meals - prevents overeating
- Add water to foods - rice, beans expand
- Serve vegetables first - fills stomach
- Limit snacking - scheduled meals only
High-Calorie, Low-Weight Foods
| Food | Calories/lb | Best For |
|---|---|---|
| Cooking oil | 4,000 | Bug-out bags |
| Nuts | 2,700 | Snacking |
| Peanut butter | 2,600 | Meals |
| Chocolate | 2,400 | Morale |
| Dried meat | 1,800 | Protein |
| Rice | 1,600 | Staple |
| Beans | 1,500 | Staple |
Cooking Without Power
No-Cook Meal Ideas
- Canned beans + crackers
- Peanut butter + bread
- Canned tuna + crackers
- Trail mix + dried fruit
- Granola bars + jerky
- Canned soup (cold)
- Canned fruit + nuts
Alternative Cooking Methods
| Method | Fuel Needed | Safety |
|---|---|---|
| Camp stove | Propane/butane | Use outdoors only |
| Charcoal grill | Charcoal | Outdoors, ventilated |
| Fire pit | Wood | Outdoors, safe area |
| Solar oven | Sunlight | Safe, slow |
| Alcohol stove | Denatured alcohol | Indoors risky |
DANGER: Never use outdoor cooking equipment indoors. Carbon monoxide kills.
Common Mistakes
| Mistake | Consequence | Prevention |
|---|---|---|
| Only storing food you dont eat | Waste, malnutrition | Store what you actually eat |
| No water storage | Dehydration | 1 gal/person/day minimum |
| Forgetting rotation | Expired food | FIFO system, monthly checks |
| No cooking plan | Cold meals | Alternative cooking methods |
| Ignoring nutrition | Health issues | Multivitamins, variety |
| Too much salt/protein | Dehydration, kidney strain | Balance with water, veggies |
Quick Calculator
Monthly Calories Needed (Family of 4):
2 adults x 2,250 cal x 30 days = 135,000
2 children x 1,800 cal x 30 days = 108,000
TOTAL = 243,000 calories/month
Rice Equivalent: ~150 lbs white rice/month (at 1,600 cal/lb)
