Backpacking meals: count calories per ounce you carry

Quick answer

On the trail, the meal that weighs least for the energy it gives wins. Divide calories by net weight: Peak Refuel's Beef Stroganoff lists 810 calories in 5.00 oz, or 162 calories per ounce, while Backpacker's Pantry's Pad Thai with Chicken lists 850 calories in 6.7 oz, about 127 per ounce. Then check the water and the wait: Peak Refuel calls for 1 1/4 cups of boiling water and 10 minutes, Backpacker's Pantry 1 1/2 cups and 15 minutes.

Three trail meals compared

Spec	Peak Refuel Beef Stroganoff	Backpacker's Pantry Pad Thai with Chicken	Backpacker's Pantry Fettuccine Alfredo with Chicken
Calories per pouch	810	850	590
Net weight	5.00 oz	6.7 oz	5.0 oz
Calories per ounce	162	about 127	118
Protein	41 g	42 g	40 g
Boiling water	1 1/4 cups (10 oz)	1 1/2 cups (360 mL)	1 1/2 cups (360 mL)
Wait	10 min	8 + 7 min	8 + 7 min
Allergens listed	Milk, wheat	Peanuts	Egg, milk, wheat

Calories per ounce is plain division of each maker's calories by its net weight.

Why calories per ounce matters

• Weight adds up: food for several days adds real weight, so a meal with more calories per ounce lets you carry the same energy for less weight.
• Compare whole pouches: Peak Refuel lists its Beef Stroganoff as 2 servings of half a pouch each. Divide the pouch total, not the serving, by the pouch weight.
• Protein is similar: all three list 40 to 42 g per pouch, so calories and weight are the bigger differences here.
• Plan from calories: a pouch labeled two servings may still be one dinner for a hungry hiker, so add up the calories you need per day and pack to that.

Water and fuel on the stove

• Boil what the label says: 10 oz for the Peak Refuel stroganoff, 12 oz (1 1/2 cups) for the Backpacker's Pantry meals.
• Watch for mixed instructions: Peak Refuel's page also advertises boiling just 6 oz (3/4 cup). Its preparation steps and spec list say 1 1/4 cups (10 oz), so plan with 10 oz until the package says otherwise.
• Time: Backpacker's Pantry has you stir and wait 8 minutes, then another 7; Peak Refuel lists 10 minutes.
• Oxygen absorber: both makers say to remove it before adding water.

Planning three trail dinners

A quick worked example using the makers' figures for three dinners:

• Peak Refuel Beef Stroganoff x 3: 2,430 calories for 15.0 oz of food, plus 30 oz of water to boil.
• Backpacker's Pantry Pad Thai x 3: 2,550 calories for 20.1 oz of food, plus 36 oz of water.
• Matching 2,430 calories with the Fettuccine Alfredo: about 4.1 pouches, or roughly 20.6 oz of food.

The difference of 5 or so ounces is small for one night and noticeable over a week. Mix meals for variety, and count the boiling water toward your fuel plan: 30 oz is just under 4 cups.

Diets and allergies

• Gluten-free and dairy-free: Backpacker's Pantry lists its Pad Thai as gluten-free, dairy-free and soy-free, but it contains peanuts, with separate peanut butter and peanut packets.
• Nut-free: its Fettuccine Alfredo is listed nut-free and soy-free, with egg, milk and wheat.
• Real meat: Peak Refuel says its meals use real meat, with no TVP.
• Read every pouch: recipes change; check the current label before a trip with allergies.

Trail meals in an emergency kit

The same pouches work in a go-bag or car kit because they need only hot water and no pot cleanup. For long-term storage at home, compare buckets and No. 10 cans by total calories and water needed; see our freeze dried food guide. For the difference between freeze-dried and dehydrated food, see our freeze dried vs dehydrated guide.

What to look for when you buy

Questions people ask

What are the best freeze dried backpacking meals?

Compare calories per ounce, water and wait time; Peak Refuel's Beef Stroganoff lists 162 calories per ounce.
