Replacing meals with a protein bar might seem tempting, but it’s not recommended. While they can serve as nourishing snacks between larger meals, they lack the comprehensive nutrition of a full meal. And though studies highlight the weight loss benefits of meal replacements, these typically offer more vitamins and minerals than a mere protein bar.

Yet, their artificial ingredients and sugar alcohols will not be suitable for those with weight loss goals.
