Best Nutrition Bars

Listen to this article:

Go to a health food store, grocery store or online retailer in search of a protein bar, and chances are you’ll be dazed and confused by the vast array of products and claims. All you want is to find the best nutrition bars, but where to begin?

Some are high in this. Others low in that. Organic. Gluten free. Non-GMO. Whey. Soy. Plant-based … Lucky for you we’ve done the homework, analyzing dozens of leading brands to find the best nutrition bars for weight loss to help you attain your personal health and fitness goals.


Origins of today’s protein bar

In ancient or even prehistoric times, it’s quite likely humans were eating dried, cured meat from game animals. In essence, that was a very simplistic protein bar.

Fast forward thousands of years to when man took to the seas, and history finds examples of Egyptian and Roman sailors eating small loaves of dried bread, prepared with grains such as millet, barley and rye. Later, England’s Royal Navy made famous their own long-lasting food ration dubbed “hardtack.”

In the early 1970’s Pillsbury Company developed a product they called Space Food Sticks. Touted as an “energy snack in rod form containing nutritionally balanced amounts of carbohydrate, fat and protein,” this forerunner of the protein or energy bar was first marketed to NASA as astronaut food, then to the American public as a healthy snack food.

By the 1980’s, Space Food Sticks had gone the way of the Ford Pinto. Onto the scene, however, emerged new snack foods that came as bars. This included granola bars targeted at school-age children, and a solid lump of calories called the Power Bar. Needless to say both found tremendous success, given that they continue to sell by the millions now deep into the 21st century.

Protein bar vs. energy bar: what’s the difference?

Of course, in today’s marketplace a lot of this has to do with, well, marketing. But on a fundamental level, it depends on what macronutrient the bar contains in highest (relative) amount — carbohydrate, fat or protein.

Carbohydrates are best known as forms of sugar, the preferred source of fuel for most cells of the human body. Thus, if a bar is mostly carbohydrate, it’s technically an energy bar. The same is true for fat — because at nine calories per gram (versus four each in carbs and protein), fat is the most energy-dense of the macronutrients. And finally, products with modest amounts of carbs and fat, with lots of protein, should be considered protein bars.


Where do granola bars fit in?

Granola bars, by and large, do not meet the standard of a true protein bar. Their main ingredients include oats and sugar (honey, corn syrup, etc.), and often raisins or chocolate chips — all of which are carbs.

They carry the benefit of “whole grains” (oats) and sometimes nuts or seeds, along with a smattering of vitamins and minerals, but are otherwise little different than your average candy bar. Yes, they’re good for an energy boost, but often at the expense of a spike in blood sugar as well.

If you struggle with pre-diabetes or diabetes especially, granola bars are not the best choice for balanced nutrition. And if you’re asking, what are the best granola bars for weight loss? The answer is, ones that are really protein bars — and just happen to have some granola in them.

Carbs, fat and protein: striking the right balance

So what about this power struggle between carbohydrates, fat and protein? How much of each is too little or too much? As you might guess, there’s no one right answer to this question — just uneducated guesses and expert opinions. Rest assured what we’re presenting here is the latter for sure! By our standards, the best protein bars or the best granola bars for weight loss will meet the following criteria:

Choosing a nutrition bar:

Calories: < 250g
Protein: > 10g
Carbs: < 25g
Fiber: > 5g

These are the four items on the product label you should be focusing on. And if you’re screening for the best nutrition bar for weight loss, ignore the carbs — and especially added sugars — at your own peril! Keep in mind that while carbs are the body’s preferred fuel source, any of this fuel your body doesn’t actually need will be stored away — as fat. Depressing, right?

Unfortunately, you can’t change your physiology, but you can do a better job of estimating your true energy needs. Sitting at a desk, in a driver’s seat or on the couch at home doesn’t require a lot of rapidly available energy. So dial down the calories and the carbs in your nutrition bar of choice.

On the other hand, if you have a job requiring hard physical labor, are a serious weightlifter or athlete who works out more than a few hours per day, you could definitely make the case for more calories, carbs and protein in a bar — or simply eat two at a time!

The ingredient list: less is more

After scanning the nutrition facts label, next glance over the ingredients list. This can be intimidating, but it doesn’t have to be. In fact, if the list is too long and full of words you don’t understand, give that bar the axe and move on. Ideally the list will be quite short, with items that sound like actual foods, not chemical compounds. Bonus points if it’s totally free of artificial sweeteners like sucralose, which has shown to negatively affect gut bacteria and even promote insulin resistance, a precursor to diabetes. Perhaps not the ideal choice for those trying to lose weight! (1)

Also, in a perfect world anyway, the best nutrition bars will be socially and environmentally responsible products. In our opinion, that means looking out for palm oil. According to the World Wildlife Fund, palm oil production in Indonesia and Malaysia is responsible for excessive deforestation — also meaning destroyed habitat for orangutans, rhinos, elephants and other endangered species.(2)


The main protein source: a key ingredient

Last but not least, take a look at the main protein source, which should be one of the first two or three ingredients listed. Common proteins used in the supplement industry include whey, soy and other plant-based derivatives such as pea protein. While there’s not a vast difference in terms of your body’s ability to utilize the protein — whether for tissue repair, energy or otherwise — there are some subtle differences. And, as you might expect, we have a favorite.

Important information

Whey protein has been shown to have a positive effect on insulin
and blood glucose regulation. It also tends to suppress appetite.(3)


But that’s not all! Whey protein has shown many other promising health benefits. These include lowering blood clot formation, blood pressure and cholesterol, as well as helping the body combat both viruses and bacteria.(4)

Whey protein isolate is superior to the concentrate form, as it contains a much higher percentage of pure protein. Whey hydrolysate is further purified and the proteins partially broken down making them easier to absorb. Whey also contains high amounts of the amino acid leucine, which stimulates muscle repair.(5) And as compared to plant based protein (soy, pea, wheat, etc.), whey has has greater anabolic (body building) potential overall.(6)

Dairy. Herbs and spices. These things have nourished our evolution for thousands of years, and if all goes well, they’ll take us into a bright and sustainable future of healthy eating.
