Meal replacement bars are a great source of fast fuel for workouts, hikes or simply day to day activities. If you often find yourself in a rush, struggling to avoid unhealthy takeout that will ruin your health goals, these wonder bars are a great solution. Clocking in at under 300 calories, the best meal replacement bars will be a great source of protein, fiber and fat and they’ll tie you over until your next healthy meal. 

But what makes a good meal replacement bar?

Well, first of all it’s important to remember that these bars aren’t made to be relied upon long term. They’re best used as on the go solutions for when you’re not around a healthy meal option or when time simply doesn’t allow you to choose the most nutritious option. 

That being said, a good meal replacement bar will have plenty of protein, fiber and fat. This will ensure that it fuels your body with the appropriate macronutrients for optimal functioning. Also, this combination will keep you feeling full and satisfied until your next meal.

Ideally, a good meal alternative will also include some micronutrients like vitamins and minerals, to compensate for the missing fruit and veg, but that’s not a deal breaker if you’re only looking to replace a couple of meals here and there. 

Last but least – taste. We like our bars tasting delicious and almost like we’re cheating with a sumptuous dessert. That’s why the options on our list check both the taste as well as the nutritional box. From fudgy chocolate to decadent caramel and velvety peanut butter, there’s something for everyone!
