As a naturally skinny guy, you not only need to consume a surplus of calories, but you also have to keep in mind the hormonal effect of the food you eat. The protein bar market is flooded with a myriad of options, but most of them contain way more junk than quality muscle-building ingredients.

Most of the protein bars you will find on the market contain ingredients that will leave you with a stomachache, an insulin spike, or a horrible aftertaste in your mouth that resembles chalk.

I have tried just about every protein bar known to mankind and am excited to share what I believe are the best protein bars for naturally skinny guys and ectomorphs. These protein bars are all delicious options that will help you create a strategic calorie surplus without lowering your anabolic hormones. Many protein bars that taste good contain so much junk, artificial ingredients, and sugars that they are much more likely to be stored as body fat than help you with your lean muscle gains.

I just wanted to also point out that I am not affiliated with any of these supplement companies in any way. These are just the protein bars that I have decided are the best for naturally skinny guys in creating a high protein calorie surplus and helping with rock-solid lean muscle gains. They are also all delicious options that will go down easy without that chalky consistency and aftertaste that is associated with so many protein bars.

Let’s dive right into the three best protein bars for skinny guys to gain lean muscle mass.

Best Protein Bars For Skinny Guys #1: Quest Bars

Best-Protein-Bars-for-skinny-guys-quest-bar-cookies-and-creamQuest bars are not as high in calories as the other two muscle-building protein bars, but they have such an incredible ingredient profile that translates into feeding your sweet tooth and helping you with hard earned lean muscle gains.

Quest bars are my favorite protein bar to consume during cutting/beach season because they are under 200 calories per bar and contain almost NO SUGAR. This means that they do not give you that insulin spike associated with many of the best tasting protein bars.

Some of the best tasting protein bars contain a massive amount of sugar, which will spike your insulin and cause you to become fatigued and store body fat. Even as a naturally skinny guy, you want to avoid this like the plague! Low energy levels and storing body fat is not going to give you the physique of your dreams.

The problem with a lot of naturally skinny guys is that they seem to think they can eat whatever they want while ignoring the hormonal consequences of their decisions. With Quest bars, you don’t need to worry about anything but a delicious taste and lean muscle gains!

Quest bars are so delicious that they satisfy my sweet tooth every single time I chow down on them. In fact, it is really hard for me to eat just one, and I usually end up eating 2 or 3 in one sitting! Since they contain 20 grams of protein per Quest bar and almost no sugar, I don’t feel the least bit guilty consuming more than one.

Quest bars are really high in fiber and contain a special kind of plant-based fiber that has a sugary and sweet taste that makes up the base of the bar.

I’ve tried all of the Quest bar flavors, and there are three that stand head and shoulders above the rest when it comes to taste. The chocolate chip cookie dough, cookies and cream, and white chocolate raspberry Quest bars are much better than the rest, so if you are a Quest bar newbie, I highly recommend starting with one of these.

Quest bars are becoming immensely popular worldwide, and you should be able to snag them on just about any popular supplement website.

Quest bars are the perfect ingredient profile because they contain no junk and fillers, and the main ingredients are a natural prebiotic fiber, almonds, and milk protein isolate. They contain 21 grams of carbohydrates per protein bar but 17 grams of fiber, giving them only 4 grams of net carbs!

If you are a naturally skinny guy looking for the best tasting and highest quality ingredient profile to support your high protein muscle-building diet, look no further than delicious Quest bars.

Best Protein Bars For Skinny Guys #2: MET-Rx Big 100

Best-Protein-Bars-for-skinny-guys-MET-Rx-Big-100MET-Rx’s meal replacement/protein bar comes in a few delicious options and contains a plethora of powerful muscle-building ingredients.

These protein bars will help you create a strategic high protein calorie surplus because they contain 410 calories, 32 grams of protein, 41 carbs, and 14 grams of fat. They are also an excellent source of vitamins and minerals.

The MET-Rx BIG 100 Colossal is my favorite protein bar for bulking season because they are much more caloric than Quest bars and still contain a ton of muscle-building ingredients. The peanut butter pretzel flavor is delicious, and if you want some winter bulking season gains, make sure to chow down on one daily for a muscle-building calorie surplus.

Best Protein Bars For Skinny Guys #3: Detour Low Sugar

Best-Protein-Bars-for-skinny-guys-Detour-Low-SugarDetour bars have been around for a few years, and the first time I ever tried a Detour bar, I was blown away by how similar it tasted to a regular candy bar. The caramel peanut Detour bar tastes strikingly similar to a Snickers bar and contains about 10 times the amount of protein!

Detour Low Sugar bars contain just as much protein as the regular Detour bars without all of the added sugar and junk. That is why they are ideal protein bars for naturally skinny guys. They will not leave you feeling tired and lethargic from the insulin spike, and they will help you create a strategic calorie surplus. The chocolate peanut butter and caramel peanut are my personal favorite Detour Low Sugar bars. If you are a big fan of the traditional candy bars like Snickers, swapping a Detour Low Sugar bar is a great choice for a high protein diet.

  • So I’m 140 lbs and am 5’10- 5’11ish… I am a track athlete and I play football in the summer. I am currently lifting after school everyday but my broblem is my nutrition… I have this one specific brand of protein that I would like for you to review for me and see if it’s best for me to have a regular protein to use after lifts and even after track practice. I watched a lot of your videos about taking mass gainer and am more interested in making my own mass gainer is you prefer that for me. My ultimate goal is to hit 160-170 by August of 2018 it is currently February of 2018.
