High Calorie Bars For Weight Gain


What are the best high calorie bars for weight gain? Getting enough calories is crucial for gaining weight. But what about protein intake and other nutrients? Well, that’s a whole other article. But in this one, we’ll be talking exclusively about protein bars.

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!

The Best High-Calorie Bars for Weight Gain

A great way to increase your calories and promote weight gain is by eating high-calorie bars.

They’re convenient, transportable, and, of course, they pack a lot of calories and protein.

But with the dozens of options, and many being marketed as low-calorie or low-carb, trying to decide which one is the best for weight gain is no easy feat.

To make your decision easier, here are the 5 best high-calorie bars for weight gain that provide at least 300 calories and 20 grams of protein, plus 2 homemade high-calorie bars to try.

high-calorie bars for weight gain

Packing around 400 calories and 30 grams of protein each, these are great bars for weight gain.

MET-Rx labels them as meal replacement bars, but they’re better eaten as a snack for gaining weight since they’re loaded with calories and protein.

Of the eight flavors they offer, the super cookie crunch is by far my favorite.

Here’s the nutrition breakdown:

  • Calories: 380–420
  • Fat: 10–14 grams
  • Carbs: 42–48 grams
  • Protein: 30–32 grams

These bars are also an excellent source of multiple vitamins and minerals, including vitamins A, C, E,D, and B12, zinc, calcium, and iron.

MET-Rx Big 100 bars contain protein from soy and milk.

In addition to these bars, MET-Rx makes a protein powder that is also good for weight gain.

If you’re unsure what flavor you might like, their variety pack is a great place to start.

The Detour Lean Muscle bar is comparable to the Met-Rx Big 100 bars in that they provide around 400 calories and 30 grams of protein.

Here’s the nutrition breakdown:

  • Calories: 370–420
  • Fat: 12–18 grams
  • Carbs: 33 grams
  • Protein: 32 grams

They are also an excellent source of vitamins A, C, E, and B12, and a good source of magnesium, calcium, iron, and zinc.

Detour Lean Muscle bars contain protein primarily from whey protein but also casein.

Both proteins are derived from milk, but whey protein digests at a much faster rate than casein.

Created by celebrity chef, Robert Irvine, the FITCRUNCH bar is an excellent high-calorie choice for weight gain.

FITCRUNCH bars come in a snack and a meal size.

The snack size provides about half the calories as the meal size, so opt for the latter for the extra calories.

Here’s the nutrition breakdown:

  • Calories: 380
  • Fat: 16 grams
  • Carbs: 27 grams
  • Protein: 30 grams

FITCRUNCH Bars contain protein from both milk and soy.

While known primarily for its sports drinks, Gatorade also makes great high-calorie bars.

Their Whey Protein Bar was developed for athletes to help rebuild and refuel, but it’s perfect to eat as a snack for weight gain too.

Here’s the nutrition breakdown:

  • Calories: 330–350
  • Fat: 10–13 grams
  • Carbs: 40–43 grams
  • Protein: 20 grams

The Gatorade Whey Protein Bar is also a good source of calcium and iron.

As the name implies, these bars use whey as the protein source.

Types of Weight Gain Bars: What Is the Difference?

types of protein bars

The main difference between different types of supplement bars is their nutrient profile. This determines what they’re for in the diet, what they do in your body, and whether they target weight gain or loss.

Supplement bars include protein bars, granola bars, mixed nutrient bars, energy bars, and even meal replacement bars.

Granola bars and mixed nutrient bars offer different nutrients, a different focus, and different benefits as part of the ‘big picture’ of your diet.

Meal replacement bars are even more different, typically aiming at higher micronutrient content and better hunger-satiety for dieting.

Protein Bars: How Do They Work?

High calorie protein bars are a convenient way to get more protein in your diet to provide essential resources for muscle-building.

This is the most important and healthy way to gain weight. Protein intake stimulates building new muscle proteins, which go into the repair and growth of your muscles.

This is a key part of both the quality and quantity of muscle growth. More protein typically means better results, as well as being a way of improving dietary control.

It’s also associated with other benefits like connective tissue and bone health, as well as metabolic and digestive regularity.

Protein is both the most rewarding and most choresome nutrient to consume. Adding protein bars, just like adding shakes, can be an easy way to increase your intake without cooking another meal, or needing access to a kitchen at all.

Granola Bars: Normal and High-Protein Variations

best high calorie protein bars

Granola bars and nut/seed bars are also popular. These aren’t directly related to fitness and performance, but can offer a great source of calories between meals. They’re packed with wholegrains, nuts, and seeds to provide a blend of high-calorie ingredients.

The carb and fat content of these bars is typically high. They’re a high-energy snack, and the protein may not be as good as in protein-specific bars. This is deliberate, but you can also find high-protein granola bars that bridge the gap.

High-protein granola bars typically resemble very small meals when you look at the nutrients. They’ve got all 3 macronutrients in good levels, as well as vitamins and minerals.

They’re just dry, small food bars and weight gain comes from eating food.

What Are Energy Bars?

Energy bars are supplement bars typically high in both calories and protein. They’re also typically fast-absorbing, processed foods to help increase the delivery of nutrients – carbs and protein alike – into your bloodstream.

These are often used in hikes and endurance sports for their high calorie and protein levels. They are also further removed from real food, due to the processing and higher glycaemic index (GI) that makes them fast-absorbing.

Energy bars have varying levels of protein. Technically, the “energy” is just about calories. The actual composition of the nutrients varies from product to product.

This is also how we’re reviewing them, for both the amount of energy they provide and where those calories come from.

Meal Replacement Bars: Are They Good for Weight Gain?

eating protein bar

Meal replacement bars can be used to support weight gain as a snack. They’re designed to be more nutritionally-complete and offer an alternative to a full meal. This typically means a combination of fats, carbs, and protein along with vitamins and minerals.

It also usually involves additional fiber to slow digestion. Slower digesting meal replacement bars help to curb hunger and cravings. They are not as effective for weight gain since the main goal is to reduce appetite.

The key to making meal replacement bars effective for weight gain is to use them as snacks, instead of meal replacements.

This is a great way to support your diet with the complete spectrum of nutrients, which can support metabolism and recovery to support healthy weight gain.

Weight Gain Bar Reviews

We’re reviewing the top 15 most popular and relevant bars on the market. We’ve tried dozens of others, but these are the most interesting and worthwhile for your attention.

What makes a supplement bar worth your time, or worth reviewing? How can they help you gain weight? There are a few factors we look for:

  • High protein content
  • High carb content (for granola, energy bars, and meal replacement bars)
  • Healthy fats (like Omega-3s or MCTs)
  • Vitamin and mineral content
  • Additional ingredients that support health, performance, or recovery

Then we look at the more personal, experience factors: taste, texture, convenience, and what it’s like to use. These add up to a 3-dimensional picture of what a bar is like, what it does in your body, and what it’s like overall.

Based on the protein content, calorie content, and several other factors that help gain healthy weight, MET-RX Big 100 Protein Bar is our best recommendation for a weight gain bar. Some other great high calorie protein bars for weight gain include:

1. MET-Rx Big 100 Colossal Protein Bars, Healthy Meal Replacement Snack

high calorie protein bars

Big100 are high in both calories and protein, clocking in around 400 calories per bar, with 30-32g of protein depending on the flavor. They’re mostly carbs, too, which makes them perfect meal bars for weight gain.

The balance of nutrients in these bars is a great place to start, offering up the 2 main ingredients you need for muscle gain. They’re also rich in a range of vitamins and minerals – far more than any other bar on this list.

This makes the Big100 colossal protein bar our #1 choice for hardgainers trying to build muscle and improve workout recovery. It’s a great choice if you’re looking for a weight gain bar that hits hard on the most important factors: calories, protein, and taste.

High in calories (around 400 calories per bar)The single bar is expensive
High in protein & carbsMostly Out-of-Stock on the website
Rich in vitamins and minerals
Tastes amazing in the Birthday Cake flavor


Uncut offers a bar that is rich in both protein and calories. This is perfect for weight gain, with 16g of protein and 23g of carbs. It also includes 16g of fats, which make it a well-balanced bar with a ‘neutral’ nutrient profile, favoring neither carbs or fats.

This makes it a perfect balanced high calorie protein bar on macros and calories alone. It also provides supplementary calcium, iron, and potassium. These are small, but pleasant, additions to support total electrolyte intake.

This is a great all-rounder and offers 290 calories total. Uncut have earned their #2 spot with a simple and effective approach to high-protein bars for weight gain. It’s less heavy-duty than the Met-Rx alternative, making it a good snack at a slightly lower calorie count.

Low calories per barThe calories may not be enough to help maintain a calorie surplus
Contains essential vitamins and mineralsProtein content is lower than some other bars
Tastes great in Chocolate Chip flavor

3. ONE Protein Bars, Chocolate Chip Cookie Dough, Gluten Free Protein Bars with 20g Protein

great weight gain bar

The ONE protein bar is a great, lean favorite. It has a lower calorie content than others on this list, making it a versatile choice, clocking at roughly 210 calories per bar – depending on your choice of flavor.

It’s main selling point is the 20g of protein and 1g of sugar, making for a fantastic protein content and metabolic benefits. The remaining NET carbs are 14g of starches for sustained-release energy.

ONE is a great all-rounder protein bar with less focus on weight gain. It can help curb cravings, it can be a great snack between meals, or be combined with high-calorie foods as part of a full weight gain meal.

Chocolate Chip Cookie Dough and Birthday Cake are the best flavorsModerately expensive
Only 1g of sugar per servingNot very high in calories
Gluten Free

4. Quest Nutrition Chocolate Chip Cookie Dough Flavor Protein Bar

Quest bars are one of the most famous names in meal bars for weight gain. This product is a great example of why: 21g protein, 1g of sugar, and 14g of fiber. This is a lower-calorie bar that is about protein purity, though does offer a smaller overall calorie content.

There are 8g of NET carbs, which include 7g of starches. The end result is relatively low in calories, making it versatile but less effective in weight gain diets. It needs to be combined with other foods to get muscle-growth numbers of calories.

Chocolate Chip Cookie and Cookies & Cream are the best flavorsCarbohydrates content is not very high
Only 1g of sugar per bar
14 grams of Fiber per bar

5. Clif Builders

high calorie bar for weight gain

Clif builder’s protein is a protein bar, as the name implies. It’s also one of the best tasting bars on the market. They offer 20g of protein from 290 calories, making for a protein- and calorie-rich choice.

They’re comparable to others on the market on the nutrition data alone. With more carbs than any other product on the market, per gram, it also makes Builder’s protein a great source for workout carbs and protein.

The 1:1.5 ratio of protein to carbs is a great choice to drive up muscle growth and repair after workouts. The lower fat content also makes it faster absorbing, beating out some of the competitors on the market.

As mentioned, Clif bars also taste surprisingly good. This isn’t on the nutrition label, but it does make the process far more enjoyable!

Cheaper than other bars in this listHigh in sugars (17 grams)
High carbohydrates content
Tastes great in Vanilla Almond and Crunchy Peanut Butter flavors

6. Greenbelly Meal2Go Bars

This is a meal replacement bar, which can make it a great choice for weight loss diets. In a weight gain diet it’s more like a snack. It’s a balanced nutrient profile with a near-equal fat, and carb content (by calorie).

The protein content is relatively low, comparatively. These bars contain 17g of protein on average, which is fine compared to others on the market, but represents a much smaller percentage of the 660 calorie content.

These are great for adding more calories to your diet, as well as a bunch of extra vitamins and minerals, but not protein. They’re a high-energy / granola bar, but not a protein bar

They support weight gain from a different angle to most of the others on this list, which is why we’ve included this as a meal replacement bar for weight gain.

One of the highest bars in terms of calories (around 600 calories per bar)Only 17 grams of protein, given the high calories
96 grams of carbohydrates per bar26 grams of fat per bar, may not be suitable for those looking to build lean muscle and need low carbs and fats
Great for using in between meals to increase calories for the day
Has some great tasting unique flavors such as Cranberry Almond and Mango Cashew Coconut

7. Dark Chocolate Chip YES Bar

This is a paleo bar, which means that it’s going to be focusing more on nuts and seeds than others on this list. It has a predominantly fat-centered nutrient profile, with 5g of protein, 17g of fat, and only 13g of carbs.

This makes the YES bar a surprisingly trim 220 calories, with 3g of fiber. It’s a simple and relatively snack-y bar that doesn’t have the same content as a Big100 or GreenBelly bar.

This is a lightweight product that can help with protein between meals, but lacks the total calorie content to be used as a weight-gainer bar by itself.

Cheaper than other bars in this listLow in protein per bar (only 5 grams)
Plant-based barHigh in fats (17 grams)
