8 Best Protein Bars, According To a Nutritionist

Maintain lean muscle and curb your cravings by eating one of these low-sugar, high-protein bars.

There are very appropriate times for protein bars, but those probably occur less than you think. Protein bars are great to those of us who lift weights — it’s hard to get all the muscle-repairing nutrients without eating steaks upon steaks. For those who are looking for a post-workout meal on the way to work. And for those that are replacing that rare meal after being caught in meetings or traffic — because a bar is better than fast food any day.

And that’s about it. Why? This is not any nutritionist’s idea of a healthy snack.

“There could be upwards of 250-300 calories,” says Jennifer Silverman, a New York-based nutritionist.

Furthermore, many of these bars are packed with fillers. Even if you are working out, “avoid any bars with added sugars or fake sugars such as sucralose, erythritol, and aspartame. Instead look for bars that have ingredients you can pronounce and natural sugars,” says Silverman.

What’s the ideal protein bar?

According to Silverman, the maximum level of sugar a protein bar should have is 14 grams per serving, plus some form of fiber, which will help you digest it slowly and release its energy evenly. If you are looking to shed weight, the maximum calories a bar should have is 200. Any more than that and you could be sabotaging yourself. If muscle gain is your goal, a bar should have at least 20 grams of protein.
