Can Meal Replacement Shakes Help You Lose Weight?

Keep that stubborn body fat off

Nutrition is one of the biggest pieces of the puzzle when it comes to your fitness journey. Your training is huge, but without proper nutrition you won’t lose weight nor will you build muscle mass. That being said, meal prepping can be a tedious task that takes up a lot of time, and many people do not want to do it, and instead they eat less than ideal meals that do not fit the macros, which leads them to not losing any weight. However, with products like meal replacement shakes, you can save yourself time and still hit your macros. 

Importance of Macronutrients

In your fitness journey, hitting your macronutrients is one of the most important things you can do. The proper amount of nutrients in your body not only will help you recover from training and truly grow, but also do things like regulate hormone levels, provide energy, and really improve your quality of life. Whether you are looking to cut down or bulk up, you are going to want to have proper protein, fat, and carbohydrate intake to do so effectively. 

Now, that being said, you will have to focus on nutrition which means prepping meals and a lot of food. With a busy lifestyle, shopping for and preparing all of that food can really become a chore, and this leads to many people not doing it. Instead, they opt for things like takeout meals and frozen dinners, and that is a huge reason many people do not hit their desired goals. However, products such as meal replacement shakes are designed for those with a busy lifestyle, but still want to obtain their fitness goals.

Meal Replacement Shakes Overview

So what are meal replacement shakes? Are they just blended up meals thrown into a shaker cup? Well, no not really. Meal replacement shakes come in bottles, or powder form that can be mixed with a beverage of your choice. They are designed to replace a regular meal, and can be used to bulk or cut.

Most meal replacements contain an adequate amount of protein, carbs, and fats, as well as things like fiber and vitamins to keep you full and moving at an optimal capacity. Depending on your goals, meal replacements can be a great way to hit your macros without the stress of buying food and preparing a meal.

Pros and Cons

As with anything, meal replacement shakes have their pros and cons. So, what does that entail?


  • Great for Weight Loss: Many meal replacements are high in fiber and protein, which help to keep you full longer, and you will avoid those cheat meals and snacks that just set you back.
  • Time Saving: Meal replacements eliminate the process of preparing a full meal, so you won’t need to pick up fast food or any other form of take out. 
  • Solid Ingredients: If you find a good meal replacement that has whole food ingredients, then you are getting the benefits of eating a true, healthy meal, which can help you reach your weight loss goals faster.
  • Affordable: Meal replacement shakes can be affordable ways of getting in a whole food meal.


  • Can Be Junk: It is no secret that the supplement market is saturated. That being said, there are plenty of junk meal replacement products out there that will not help you achieve your weight loss goals, so you have to be wary of what is in each product.

What to Look for in Meal Replacements

When looking for a good meal replacement, you want something that contains whole foods, not junk blends and is pumped full of sugars. You also will want a meal replacement with substantial calories and the right macros, to make sure you are getting the proper caloric intake and a good amount of macronutrients to effectively hit your fitness goals.

You also do not want a product that just breaks the bank and has you spending more than you would for an actual meal. 


When you lack time, forget to prep meals - or s#*t just happens - be ready with fast, flexible and complete real food macros on-demand. Designed from real bodybuilding meals for real gains!

The best part it is, FLEX FOOD is made up of whole food ingredients.

Let’s take a closer look.

What is in it?

Mutant Flex Food Nutrition Facts

FLEX FOOD contains a grocery list of real food ingredients from kale, broccoli, pomegranate, acai, and avocado to milk, quinoa, flax seed and sweet potato!


As far as protein content, FLEX FOOD comes in with a more complete blend of milk protein concentrate (80% Micellar casein), whey (concentrate, hydrolysate, isolate). This is something you do not see in a lot of other products of this nature, as many of them are either solely milk based or solely plant based.

Other sources of protein come from fermented pea, and sprouted pumpkin seed proteins. FLEX FOOD also contains 92% more BCAAs and EAAs than the collagen-like beef protein isolate other MRPs use.


Alkalizing greens balance out an acidic high protein diet while superfoods and antioxidants help to do things like boost immunity and fight endless lifting, dieting, working and whatever else you pack into your daily grind. Greens are not something you typically see in these products, which makes FLEX FOOD standout even more.


FLEX FOOD comes in with a blend of complex carbs that stabilize blood sugar, fuel your brain and give your muscles the energy needed to function properly. 


Healthy fats support nerve signaling, hormonal balance, and help to decrease inflammation from all that heavy lifting!

Enzymes, Probiotics, and Electrolytes

Digestive enzymes + pre and probiotics are also included in FLEX FOOD to ensure you break down and absorb every last nutrient while boosting gut health. Probiotic powerhouse DE111® has also been shown to improve body composition. Aside from that, quality sea salt, OrganiCal™ calcium and potassium support better muscle function and hydration – no cramping!

Price, Flavor, and Convenience

Mutant Flex Food Review

As far as price, FLEX FOOD is $44.99 for 20 quality servings, which is right around $2.25 per serving. To put that into perspective, you are getting a whole food, healthy meal, for under $3.00. 

When it comes to flavor, you may be thinking that a product with all of those ingredients has to taste disgusting, right? Wrong. FLEX FOOD currently comes in just two flavors, which are Vanilla Cupcake and Chocolate Brownie. So no, you are not going to be taking in a shake that tastes like you threw whole foods into a blender. FLEX FOOD is also not something that will be chalky, as it mixes well and has a smooth texture.

Now for convenience, FLEX FOOD allows you to get a whole food meal with good macros in just one scoop. You can consume FLEX FOOD anywhere and any time which ensures you will be hitting your macros, making it a great meal replacement shake for weight loss.
