Updated on September 29th, 2020
Meal replacement bars are a full step above nutrition and energy bar and should be held to a higher standard. Meal bars are designed to function as a meal rather than just a snack to fill in the cracks. They can be great high-calorie performance fuel, lightweight trail food or an easy meal when you’re tight on time.

Why Meal Replacement Bars?

1. Fast. A meal replacement bar is a well-balanced, immediate meal you can eat while you’re still movin’ and groovin’ on the trail. They’re carefully crafted to fill in as a healthy, full-meal alternative, and there’s no stopping or cooking required. The bars are ready-to-eat whenever hunger strikes.

2. Easy. With a meal replacement bar there’s no clean-up! There’ll be enough of that on the trail already, so it’s nice to have an alternate, satisfying food option that doesn’t take much work. Or planning. Just be sure to pack out your wrappers so they can be properly (and responsibly!) recycled or disposed of.

3. Compact. One of the great things about meal replacement bars is you can pack a whole bunch of them and they hardly weigh a thing or take up much room in your pack. They’re often no bigger than the size of your hand and they come in airtight packaging that’s durable and keeps them well protected.

4. Filling. Where granola bars, protein bars, and even ramen noodles make for great lightweight snacks or meal starters, they don’t contain enough calories or nutritional value alone to be a complete meal like a meal replacement bar is.

Hiking’s not the time to skimp on calories or pick food that falls under the “weight loss” category. Your body’s going to require extra calories to burn and hearty meals to keep it full and its energy levels up. Everyone has different nutritional needs. But, the best bars that cut it as a “meal” should provide at least 300 calories. Preferably more... especially for active lifestyles. 


Leave those small bars for snacking. Compared to granola or protein bars, meal replacement bars should be noticeably heavier and more substantial in size due to all the additional, nutrient-dense foods they're packed with. Again, let's forget about 1-2-oz bars because they just ain’t gonna cut it.


Dry, moist, sweet, salty—taste preference is up to you. Many prioritize Gluten-Free, Organic, Nut-Free, Soy-Free and Non-GMO labels as well. Personally, I keep my food as natural and minimally processed as possible. A quick glance at a label can tell if a bar is “clean” or not.

To stay minimally processed, bars should be made with only ingredients you can pronounce and free of highly processed ingredients (i.e. artificial colors, sweeteners, etc). They should also be clear of food additives like maltodextrin, for example, which is a common ingredient found in packaged foods.

It’s no secret you should always take out of the forest whatever you bring in (Leave No Trace Principles and all that.) But if you want to take your green efforts one environmentally-friendly step further, then investing in meal replacement bars with recyclable packaging is a good place to start.
Not all plastic packaging is created the same. You can tell if your bar’s plastic is recyclable by checking the back label for a symbol like 3 arrows forming a triangle (♻️), or a note about being compostable.


Protein is an essential macronutrient to any well-rounded meal. It keeps you full and helps build strong bones and muscles. Like with protein bars, different kinds of protein are used in different kinds of meal replacement bars.

Here’s a look at the most common sources:

  • Whey – Stemming from milk, whey is a complete protein with all 9 essential amino acids. It can aid in muscle recovery and growth, especially during endurance activities.
  • Soy – A staple in plant-based diets, soy comes in many forms from powder to tofu, edamame to tempeh. A ½ cup can give anywhere from 7-10 grams of protein, along with high levels of both iron and calcium (important if following a non-dairy diet!)
  • Pea – Pea protein has gained some popularity over the years, probably because you can get over 25% of your daily fiber and around 9 grams of protein in a single cup.
  • Brown Rice – This protein is a great option for people with food allergies because brown rice is hypoallergenic by nature. It’s also loaded with antioxidants.
  • Quinoa – Like oats, quinoa is a grain that’s often ground into flour and used to make baked goods. It’s a complete source of protein with around 9 grams per cup.
  • Oats – Just ½ a cup can give you over 6g/protein. It’s not a complete protein, but oats keep you full and are high quality and clean.
  • Seeds, nuts, and nut butter – An excellent source of healthy fat and fiber, foods like peanuts, almonds, chia seeds, and nut butter can have more than 2g/protein in a single tablespoon.

A health food titan. Clif Bar has a ton of flavor options, is sold everywhere, and is relatively inexpensive. It really doesn't cut it as a meal for me though. Some complain about their mealy texture and bland flavor. The bars are made with ingredients like organic rolled oats, rice flour, soy protein, and some variation of fruit or chocolate. They’re chewy, not overly sweet, and taste kind of like a healthy version of an oatmeal cookie.

Types of Bars: Extruded vs. Cold-Pressed 

There are two ways to make meal bars. Some are cold-pressed, others are made using a process called extrusion. Which process is used will affect how the bar taste and its overall texture. Let's look at each process independently.

"MEALY" TEXTURE- Ingredients usually put in a blender and injected out.

Extruded bars are made from dried ingredients that have been ground together to create a mixture. The mixture is then put through a mechanical process that includes forcing and pressing slabs full of the mixture through a machine that makes it into the desired texture, size, and shape. The cooking of the mixture is done through using large external heaters. This is a common process used in the creation of a number of packaged foods, and its method results in a very consistent, mealy texture.

 "CHUNKY" TEXTURE - Ingredients mixed together and then rolled out. 

When making pressed bars, the ingredients are first mixed and then pressed into the bar shape by a machine or roller. From there they may go on to be either baked or refrigerated. The theory behind pressed bars is that the ingredients withhold their highest level of nutritional value (and wholesome taste) because they remain in their most natural state.

Do-It-Yourself Meal Replacement Bars

With the right ingredients, you can whip up a batch of customized meal replacement bars right at home. They’re fairly easy to make and often only require some blending, mixing, melting, spreading, and baking (… or refrigerating, depending on the recipe.)

Ingredients: Many meal replacement bars include common household ingredients like: oats, nuts, seeds, nut butter, maple syrup or honey, coconut or olive oil, eggs and spices. You can customize recipes however you want by swapping out ingredients or adding other items like coconut flakes, chocolate chips, or dried fruit.

Gear: To get started on making a batch, all you need is a mixing bowl, a small pot, parchment or wax paper, a blender, a pan or baking dish, a spatula, an oven (or a fridge if it’s a no-bake bar), and, of course… the right recipe! Here’s two to get you started.

Recipes: Super Seed Chocolate Protein Bars (Vegan, Gluten-free and Nut-free option) or High-Calorie Meal Bars (Variety of flavor options)
