Are meal replacement shakes the same as protein shakes? Nope, they’re not. They are different products indeed, and serve a different purpose although there is some overlap.
Protein shakes cannot be used as meal replacements, since they don’t have the minerals and vitamins need to make them fully nutritious. So in other words, they are not the complete package. They are more a supplement to your existing diet.
What are Meal And Protein Replacement Shakes?
Meal replacement shakes are products intended to substitute the nutritional value of food, but with lower calorie intake. They can be used while trying to cut weight by substituting a meal, or if you’re on the go and don’t have time for a full meal. They contain minerals, fats, vitamins, and proteins for weight maintenance.
A meal replacement shake has a balanced nutrient profile that provides a portioned meal in the form of a shake. They are made with varied flavors such as chocolate, vanilla, chia, and mocha. They are beneficial since they are easy to prepare (really, no prep), help in weight loss, and are quick to drink. (1)
Protein shakes are drinks intended to add protein to a diet. They are mostly used for muscle gain and athletic performance. They are available in different flavors including strawberry, vanilla, and chocolate. Protein shakes can be high in sugar (but not necessarily), have no essential vitamins and minerals, and can be taken as snacks before and after workouts. (2)
Protein shakes have the following advantages:
- They increase your metabolism
- They help you to cut weight
- Helps in building lean muscle after weight training

Can Protein Shakes Be Used as Meal Replacements?
Protein shakes cannot be used as meal replacement shakes since they don’t have the range of vitamins and minerals required to make them fully nutritious. Instead, they are used to complete a meal and as amino acid supplements for a person.
Both proteins and meal replacement shakes have their uses, and both likely fit into you weekly diet.
For example, if your goal is to increase your diet’s minerals, vitamins, and general nutrition, you should go for a meal replacement shake. And there are many varieties, such as keto shakes and vegan shakes.
On the other hand, if your goal is to add more weight and muscle mass, choose protein shakes since they are great for building and repairing muscle tissues.
