Why Do You Need High Calorie Bars?

High calorie bars can benefit a lot of different people. From those who need to gain weight. To those who need a simple meal replacement. And to those who need extra energy while hiking and backpacking.

High Calorie Bars for Gaining Weight

Some people struggle with unintended weight loss and/or need to gain weight. It can be hard to get in enough calories day-in and day-out. Eating 3 meals per day plus 2-3 high calorie snacks can help you get the most calories in your day.

High calorie bars make a great snack for adding extra calories to help promote weight gain.

High Calorie Bars for Meal Replacement

Some people are looking for high calorie bars for meal replacement. Perhaps they are too tired to cook. Or they are recovering from illness/ injury. And they just need access to some easy calories. High calorie bars often contain enough calories to serve as a meal replacement.

Balanced meals are so important. But high calorie bars can be a great option for when you need some quick calories.

High Calorie Bars for Hiking & Backpacking

And finally, some people are looking for high calories bars for hiking and backpacking. When you are spending your day hiking, you are burning some serious calories. You need to make sure you can replenish those calories so you have the energy to keep going.

Additionally, hikers don’t have a lot of room in their packs to carry a ton of food. A high calorie bar is small, relatively light weight, but jam packed with calories.

Benefits of High Calorie Bars

High calorie bars offer multiple benefits, primarily the fact that they are calorie dense and convenient.

Calorie Dense

When I say calorie dense, I mean jam packed with calories! Calorie dense means there are a lot of calories in a small amount of food.

Different types of foods contain different amounts of calories. For example, fat is the nutrient with the most calories per volume. High calorie bars incorporate calorie dense foods so you get “more bang for your buck”.


There are many high calorie foods and high calorie snacks available. The benefit of a high calorie bar is that they are convenient. You can grab a bar and go. Or you can eat it at home or when out and about.

You don’t need utensils or plates. You don’t need to keep them frigerated. And if you buy them, they are even more convenient.

Types of High Calorie Bars

When it comes to high calorie bars, you have two choices: pre-made, store-bought high calorie bars or home-made high calorie bars. Within each category, of course there are a variety of choices.

Pre-made High Calorie Bars

There are a wide variety of brands and flavor choices when purchasing pre-made high calorie bars. You can find high calorie bars at the grocery store, nutrition shops, and online.

When purchasing a high calorie bar, read the nutrition facts label to learn how many calories are in the bar. Some protein bars are meant to be high in protein and low in calories. Look specifically at the calorie count to find a bar with a good amount of calories (300+ calories).

Home-made High Calorie Bars

Are you interested in making your very own home-made high calorie bars? Here are a couple of recommended recipes from our dietitian friend over at Snacking in Sneakers!
