Frequently Asked Questions (FAQs)

1. Are chocolate protein bars healthy?

You can now find protein bars resembling brownies, flapjacks, and chocolate bars at most supermarkets and corner stores. But just because they're high in protein, it doesn't mean they're necessarily good for us — some are very high in sugar and artificial ingredients.

2. Why you should avoid protein bars?

Many protein bars also contain high amounts of added sugar and use unhealthy sweeteners like high fructose corn syrup, which adds excess fructose to your diet and can increase your risk of fatty liver, obesity, and diabetes when consumed in high amounts ( 3 , 4 , 5 ).

3. Are protein bars good for weight loss or weight gain?

Protein bars can be a good source of calcium, potassium, vitamin B, fiber, and iron. They can also help you gain muscle mass and can even promote weight loss. In addition, protein bars can be a good meal replacement or post-workout snack.

4. Do protein bars make you gain weight?

You could gain weight. Many protein bars are very high in calories, on par or even higher than some candy bars. MET-Rx Super Cookie Crunch, for example, weighs in at 410 calories and 14 grams of fat. That's the same amount of fat and 130 calories more than you get in a regular Snickers bar.
