How To Choose A Healthy Protein Bar That Isn’t Candy

 by William Lagakos, Ph.D. | May 8, 2013 | Updated: May 9, 2013 |

We’ve all been there – in a rush, needing to grab a quick bite – and instead of a sandwich, opt for what you might think is a healthier alternative: the protein bar.

The problem with this “health food” is when you read the nutrition label to find that it has about 30 grams of sugar and only 15 grams of protein. Bummer.

In order to avoid consuming things that can hurt your diet, there are really just a few things you should look for when checking out the nutrition label to make sure that what you’re eating is actually healthy. And with protein bars, when you do look closely at these things, you’ll quickly find that they aren’t really a health food at all.

Tip #1 – The Protein Bar Should Have At Least 20 Grams of Protein

Quantity > 20 grams

Anything with > 20 grams is a bona fide protein bar. It has protein added for the sole purpose of increasing the protein content. In other words, the ingredients in a candy bar will never accidentally amount to over 20 grams protein.

According to the research, 20 grams will give your muscles a little burst of protein synthesis.
Moore & colleagues tested what the response of muscle protein synthesis was to increasing doses of egg protein in healthy young men after a bout of resistance exercise.¹ They show that muscle protein synthesis increases with doses up to 20 grams, but with not much improvement thereafter.

However, a study in healthy middle-aged men shows that muscle protein synthesis is maximal with 170 grams of beef, which amounts to 36 grams of protein.²

This shows us that higher protein levels are more satiating, with the cutoff seemingly around 20 grams.

In a study comparing people’s hunger when they ate a yogurt snack with either a 0, 5, 14, or 24 grams of protein, those who consumed the highest dose felt less hungry, more full, and that they could hold out longer until they wanted dinner.³

Lastly, another study comparing participant’s fullness after eating a custard with either 37 grams of casein protein or 15 grams shows that those who ate the 37 grams felt modestly fuller.⁴ For more on protein, see my article Do High Protein Diets Help You Lose Weight?

Unfortunately, not many protein bars fall into this category, and so many saturate the market making numerous health claims that it becomes confusing to decide whether any are actually good for you.

Tip #2 – The Protein Bar Should Use Whey Protein

For the best quality, look for whey, or a whey/casein blend. Some companies try to boost the total amount of protein by diluting it with soy, and if you really want an optimal snack then you should be looking for whey. It’s also an indicator that the manufacturer is making an attempt to use high quality ingredients.

Tip #3 – The Protein Bar Should Have Less Net Carbs Than Grams Of Protein

Of course, there will be other ingredients in the bar than protein, or it wouldn’t be a food. So, what other things should you take into consideration?

If whatever is left on the label is less than the amount of protein, you might have a winner. Only a few of the most popular protein bars meet this criterion.

An important consideration is the carbs you’ll be eating. Many protein bars contain sugar alcohols, which in large amounts can cause gastrointestinal problems for many people. Most bars also contain hefty amounts of artificial sweeteners and sugar, so the carbs in the protein bar is usually where protein bars start looking more like candy.

If the protein bar contains fiber, think of it as an added bonus – especially if it’s one of the prebiotic super-fibers like inulin or galactooligosaccharides.⁵ The “net carbs” in the protein bar is the total carbs minus the grams of fiber. If the amount of net carbs is less than the grams of protein, that’s a positive sign.

Tip #4 – The Protein Bar Should Have Enough Fat to Match Your Desired Calories

Basically, the amount of fat in the bar is only going to affect the calorie content. If it’s a meal replacement you’re after, then shoot for > 10 grams, but there’s not a whole lot of variety in this department.

Protein bar manufacturers haven’t gotten into optimizing their fat profiles yet, but I predict they will be doing this soon. Very soon. And when they do, look for things like Medium Chain Triglycerides (MCTs), coconut oil, cocoa butter, etc. In one study, subjects assigned to supplement with 20 g/d MCTs lost more weight than those who received olive oil.⁶

In a study by Romestaig & colleagues, rodents fed a diet enriched with coconut oil ate more calories, but gained less weight than those fed a butter-enriched or low fat diet.⁷ Lastly, unlike most common vegetable oils, cocoa butter is resistant to oxidative stress,^8 9 lacks pro-inflammatory omega-6 fatty acids¹⁰,and has a naturally long shelf-life

Tip #5 – The Less Ingredients In The Protein Bar, The Better

The most important tip of all is saved for last, which is the less ingredients you find in a protein bar, the better. If there are 20 ingredients, most of which you are unable to pronounce, that’s a sign it’s best to look for another protein bar.

Oh Yeah Protein Bar Ingredients (over 20 ingredients):
Peanuts, Protein Blend [(OhYeah!® Blend Consisting of Whey Protein Isolate, Soy Protein Isolate, Milk Protein Isolate, Milk Protein Concentrate, Calcium Caseinate), Hydrolyzed Gelatin], Peanut Butter Coating [Maltitol, Fractionated Palm Kernel Oil, Milk Protein Isolate, Partially Defatted Peanut Flour, Whey, Peanut Butter (Peanuts, Peanut Oil, Dextrose, Partially Hydrogenated Vegetable Oil {Rapeseed and Cottonseed Oil}, Salt), Salt, Soy Lecithin and Sucralose Sugar, Corn Syrup, Non Fat Dry Milk, Maltitol Syrup, Cocoa Butter, Corn Starch, Butter, Sucralose, Soy Lecithin, Natural and Artificial Flavor), Soy Nuts, Glycerine, Cocoa Powder, Fractionated Palm Kernel Oil, Lecithin (an Emulsifier), Natural and Artificial Flavors, Salt, Sucralose and Potassium Sorbate Added as a Preservative.

Almond Rise Protein Bar (3 ingredients):
Almonds, Honey, Whey Protein Isolate

Recommended: Almond Honey Rise Protein Bar

There is a protein bar that meets all the guidelines listed and is the most natural with the fewest ingredients: Almond Honey Rise Protein Bar. Here are some of the reasons why this is a healthy protein bar:

• No gluten
• No sugar alcohols
• No Soy protein
• No artificial sweeteners
• Not a lot of sugar
• 20 grams of protein, 16 grams of net carbs

If you are going to eat protein bars, taking these tips into consideration when shopping for a snack, or meal replacement, hopefully will help you find something that is good for you, your diet, and maintaining your health.

Great post. Actual useful information...

In the end you can eat the best protein bar on the planet and get fat if you dont do exercise.  The protein will become fat if it is not used, because there is a metabolic way to do so.

Do you work for that site or something? You keep linking articles to it.

No i do not work for or with BuiltLean.  However it is a site that you can learn a lot from.  Working out is in my opinion 80% knowledge of what to do.  The other 20% is just doing what you know what to do.  It is much more than just pushing weights around.  it is every bit as intellectual as physical.

I think I'll do fine by cutting down on junk food and booze, and moving my body around as much as I can. I'm not a scientist or researcher, so I take a lot of stuff circulated around the internet with a grain of salt.

Depending on your goal as well as your body type that may or may not be what you need to do.  It really depends on your goals.  

There is actual weight gainer if he is looking to gain weight and is having a hard time.
