Do Meal Replacement Shakes Actually Work?
15 min read
- Meal replacement shakes work. They can help you lose weight by reducing your calories by 300–400 kcal without making you feel hungry.
- There’s no definition of what a meal replacement shake is in the U.S.
- A nutritionally complete meal replacement shake will focus on protein and micronutrient.
- Meal replacement shakes are healthy. But you need to look out for brands that use artificial ingredients, fillers, and preservatives.
- Diabetics need to be careful of brands that have 40+ grams of carbs with 10+ grams of sugar (which is most of them).
Don’t buy a meal replacement shake, unless you read this first.
If you’re reading this post right now, it means you’re considering adding a meal replacement shake to your diet.
And, if you’re like most people, you’ve probably considered using a meal replacement shake to support weight loss.
Or maybe, like far too many of us these days, you just don’t have time to prepare a healthy breakfast before rushing out the door.
Whatever your motivations for using a meal replacement might be, we’re here to help. But before we begin, let’s make something clear.
Nobody actually NEEDS a meal replacement shake.
Let us explain.
There are a few reasons why you may be curious about meal replacement shakes:
- You’ve heard it helps you lose weight
- You want to avoid eating sugary breakfast cereals and pastries
- You don't have time to make a complete breakfast
- You crave nutrients that your diet is lacking
For these reasons, meal replacement drinks can be a great option.
As one of the most convenient ways to start your day, meal replacement shakes deliver the promise of complete nutrition in seconds that can curb hunger and support weight loss.
Sure, you can absolutely eat a healthy, nutrient-dense meal instead of enjoying a meal replacement shake for breakfast, but sometimes that’s not always practical or accessible due to the fast pace of modern life.
Our recommendation is to fuel your body with nutrient-dense whole foods as often as possible.
Eating this way will put you in the best position to succeed with your health goals over the long term.
But here’s the problem:
- Some people like not having to think about cooking breakfast.
- Some people just don’t have the time to prepare a meal.
- Many people want (and need) to get essential nutrients that modern diets lack.
- Some people just enjoy the taste and convenience.
- Others use it to give their digestion a break.
If you could relate to any of the reasons above, then swapping your traditional breakfast for a powdered beverage is a good option.
Sure, you could simply skip “breakfast” altogether by trying out different intermittent fasting routines, but let’s face it, at some point you have to eat!
A meal replacement is certainly a better option than skipping breakfast and feeling hungry and miserable all day, or eating sugary cereal and spiking your blood sugar to the moon.
Now that we’ve cleared that up, let’s dive into some reasons why people look to meal replacement shakes for weight loss or simply as a convenient way to pack more nutrients into their diet.
What Is A Meal Replacement Shake?
It's a good question, isn’t it? Because so many different brands are claiming to have the best meal replacement shake but…
In reality, there’s no definition of what a meal replacement shake is (at least not in the United States).
This creates a lot of confusion for people and makes it painstakingly difficult to evaluate the differences between shakes on the market. With everything from greens shakes to protein powders claiming to be the ideal “all-in-one” solution to daily nutrition, it’s tough to know what to choose for your specific health goals.
If you look at the meal replacement market, you’ll see wide variations in both macronutrients (protein, carbs, and fats) and micronutrients (vitamins & minerals).
But all hope isn’t lost.
After digging into the research about what actually makes a meal replacement a suitable meal replacer, we discovered that there has been an attempt to “define” everything.
A Commission (CODEX) of the Food and Agriculture Organization (FAO), a part of the UN created standards for meal replacement shakes in 1991.
These international standards were adopted by some countries like Australia, Brazil, Canada, the EU and others.
The US, however, has not adopted a standard for what a meal replacement shake should be, which is great for marketers but harmful for consumers.
Here are the requirements for a meal replacement shake according to the internationally recognized Codex standard:
|Protein||25–50% (less than 125g)|
|Vitamins||25% or 33%|
|Minerals||25% or 33%|
1. How do you define a meal?
In our opinion, a “meal” should be at least 3 things — nourishing, satiating, and delicious.
Checking these three boxes is the basic criteria, but there’s more to it than that.
You see, when you eat real food, there’s a whole host of enzymatic and metabolic activities going on that play a role in digestion, nutrient absorption, and the energetic value of the food consumed.
And, just in case we glossed over this part… that’s the whole point of food — to nourish our bodies and energize our cells so our body can perform to the best of its ability.
2. How balanced is it really?
When you eat real food, you get a variety of combinations of macros and micronutrients. This is where meal planning comes in.
So, if breakfast has a lot of fiber and minerals, we can prepare a meal with more vitamins for lunch.
But when it comes to meal replacement shakes (according to the codex standard at least), each shake should have 33% of everything.
I don’t know about you, but I’ve never had a meal in my life which had exactly 33% of all the vitamins and minerals I need.
And because most people supplement their diets with a meal replacement shake rather than surviving off meal replacements alone as some sort of dystopian future of food, they are likely getting sufficient amounts of certain nutrients from food already.
That means, using the Codex standard, without addressing the deficiencies of the other meal, then we might end up with too many minerals and not enough vitamins or vice versa.
This is exactly why we do things differently at LyfeFuel.
We use modern nutritional science and clinical research to address the deficiencies of your regular diet with our Essentials Shake, not trying to give you just 33% of everything across the board. (More on this later.)
Now that we have a better understanding of what a meal replacement shake is and isn’t, let’s look at how meal replacement shakes can help to support specific health goals that you might have.

Meal Replacement Shakes for Weight Loss
Before considering using meal replacement shakes for weight loss, you should first think about the underlying cause of your weight problem.
What exactly made you gain weight? And what is stopping you from losing it?
Despite what the dieting world wants us to believe, weight loss is a lot more complicated than simply eating less and exercising more.
It’s a complex web of psychological, biological, hormonal, emotional, environmental, and behavioral factors.
All of which are unique to every individual. And that’s why no meal replacement shake alone, and no diet for that matter, will solve your weight challenge. The only one that can do that is YOU.
The allure of meal replacement shakes is that they can fast-track your weight loss, but that’s just a gimmick. We’ve all seen this play out time and time again, especially online.
But that doesn’t mean that meal replacement powders can’t be a powerful tool in your tool belt to lose the weight you desire. You just need to know what to look for and how to choose the best meal replacement shake for your specific needs.
If you’re in a rush, feel free to click here to jump down to our top criteria and recommendations for how to make an informed choice.
For the science nerds (like us) out there, let’s continue…
To understand if meal replacement shakes are a suitable option for weight loss, we first need to understand the mechanisms of weight gain, overeating and obesity. As we pointed out earlier, weight gain is a complex problem which requires a mult-factorial and holistic approach.
First, let’s see if you have metabolic syndrome (which is not good for your health)...
What is Metabolic Syndrome?
Metabolic syndrome is the medical term for a combination of diabetes, high blood pressure (hypertension), and obesity.
It puts you at higher risk of getting heart attacks, strokes and other conditions that affect your blood vessels.
On their own — diabetes, hypertension, and obesity — can damage your blood vessels, but having all 3 together is a death sentence if ignored.
And all of these are connected to weight gain.
How to know if you have metabolic syndrome?
According to the NCEP (National Cholesterol Education Program) 2005:
If you have three or more of the following means you have metabolic syndrome.
|Large Waist Size||Men: 40 inches or more|
Women: 26 inches or more
|High Blood Glucose||100 mg/dL or more|
|High Triglycerides||150 mg/dl or using cholesterol medicine|
|Low HDL Cholesterol||Men: 40 mg/dl |
Women: 50 mg/dl
or using cholesterol medicine
|High Blood Pressure||130/85 mmHg or using hypertension medicine|
Why Calories Matter Less Than You Think
The usual way of thinking about obesity is based on the notion of energy balance. We consume more calories than we need. This surplus goes into body fat, and we gain weight.
This idea suggests that overeating causes obesity.
According to this theory, the body treats all calories the same, so the only way to lose weight is to eat fewer of them or burn more off with exercise.
But here’s the problem:
An analysis by Tufts University concluded that, after a 3-decade increase, calorie consumption in the U.S. has actually decreased since 2000. But obesity rates have increased by more than a third since then, to almost half of the population today.
So, what explains this paradox?
Some people argue we’ve reversed cause and effect.
Overeating isn’t the primary cause of obesity. The process of gaining weight causes us to overeat.
Are Carbs The Real Problem?
If not the energy balance, then what causes obesity? This is where the carbohydrate-insulin model comes in.
The carbohydrate-insulin model focuses on the processed carbs that have flooded modern diets. These carbs (like white bread, white rice, sugary foods) raise insulin levels too high and produce other hormonal changes which program our body to store extra fat.
From this perspective, obesity is a calorie distribution problem.
Too many calories going into fat tissue and too few in the blood to satisfy the energy needs of the body. So our brain makes us feel hungrier, to compensate for the lack of energy.
If we try to ignore hunger and restrict calories, the body conserves energy by slowing metabolism.
Simply cutting back calories doesn’t work because it doesn’t solve the underlying problem — a predisposition to store excessive fat.
Instead, by reducing the surge of blood glucose and insulin after meals, fat tissue can be forced to release the pent-up calories, leading to less hunger.
This can be done with a high-fat diet low in processed carbs, that can include unprocessed carbs like non-starchy vegetables, whole fruits, legumes, and whole grains.
The energy balance model contributes to stereotypes by blaming overeating on poor self-control.
If the carbohydrate-insulin model is correct, then deeply ingrained notions about obesity are simply wrong.
Overeating is a symptom, not a cause.
Did you know?
Industrialized agriculture has made our food become less nutritious with each passing year (almost 40% decline in some minerals).
Our bodies aren’t getting all the nutrients we need from food alone — this leads to constant hunger and increased cravings for junk food. (Due to the chemical effects of ultra-processed foods on dopamine and hormones.)

what makes a good meal replacement shake?
Now that we’ve cleared up a few misconceptions about how weight loss really works, you should be better equipped to make decisions about which meal replacement shake is the best for your goals.
Nutrition labels are impossible to understand and often don’t reveal all the “hidden” yet important information required to make a good decision. We've simplified things to just a few categories that we believe to be the most important when comparing brands.
A Complete Shake vs Shakes With Junk
The reason most people look for a “complete” meal replacement shake in the first place is because they crave nutrients. Nutrients they may miss out on if they simply skip a meal and nutrients that are disappearing from modern diets.
If you’re trying to lose weight then you want to be in a calorie deficit, however, the composition of the “food” you eat might be the thing holding you back from reaching your goals.
Whether you believe in the energy balance model or the carbohydrate-insulin model, one thing is clear.
The main purpose of using meal replacement shakes should be to get “complete” nutrition while helping us lose weight. A low calorie, low nutrient, high carb approach is a surefire way to sabotage your success.
Without the right vitamin & mineral balance, the body thinks it’s in starvation mode, causing it to burn lean muscle instead of fat stores.
When your body goes into starvation mode, the body’s natural reaction is to hold onto body fat. That’s because the energy we get from fat is more than 2x what we get from carbohydrates.
This is simply part of our evolutionary biology.
A better solution? Complete nutrition that is high in nutrients but low in calories and carbohydrates.
So, what do we need for a complete nutrition shake?
- The first thing we need is protein. Protein is great for building muscle, and for repairing/regeneration of your body. Plus protein has high satiety and high thermic effect.
- The second thing we need are micronutrients. We need vitamins and minerals for various processes in our body because micronutrient deficiencies can have huge ramifications on the body.
And that’s it.
So the question remains, is drinking a meal replacement shake high in carbohydrates the best idea?
Chances are you’re already getting enough carbs.
On top of that, when you consider the ways in which most people prepare and use nutritional powders, the last thing you’d want is a product already high in carbohydrates because it gives you no flexibility.
Take all the recipes online for smoothies and smoothie bowls as an example.
By conventional meal replacement standards, there’s no way you’d be able to keep carbs to a minimum using most meal replacement powders.
That’s another benefit of the Essentials Shake — you can add as many carbs or fats as you want without exceeding your macro targets for the meal. Need more carbs? Add some bananas. Need more fat? Add some flaxseeds, avocado, or MCT oil.
What you can’t do however, is remove carbs and fat that’s already in the meal replacement powder.
A good meal replacement shake should have:
- High in protein (18-25 grams)
- Low in net carbs and sugar (under 5 grams)
- All essential micronutrients in proper dosage
- A small amount of healthy fats
- No fillers, preservatives, or additives
- No synthetic ingredients

Meal Replacement Shakes for Diabetics
Diabetes is a condition where a person has excess glucose in their bloodstream. This is either due to their pancreas not making enough insulin or their cells are not responding to the insulin.
Which means that diabetics need to control their glucose levels at all times. And the best way to do that is to track your carbohydrate intake.
This is where meal replacement shakes come in.
Most meal replacement shakes are relatively low in carbs and high in protein to help maintain glucose levels and control your calorie intake.
But here’s the problem:
Though these shakes claim to be low in sugar, they actually have too many carbs and hidden sugars in them. Let us explain.
Too Many Carbs & Sugars
A lot of meal replacement shakes on the market go wrong when it comes to carbs and sugar.
1. There are so many brands that have 40+ grams of carbs with 10+ grams of sugar.
Unless you're an elite athlete, you don’t need all these simple carbs in your diet. In fact, overconsumption of simple carbohydrates and sugar will put you on a fast track for insulin resistance and diabetes.
It’s mind numbing to see how many brands overlook this.
The problem of modern lifestyles isn’t a lack of calories and simple carbohydrates. In fact it’s the exact opposite. We’re getting way too much of these things in the diet already!
That’s why diabetics in need of a product to help control blood sugar levels throughout the day should be looking for meal replacement shakes that are low in carbs and sugar.
2. Another problem diabetic deal with are the hidden carbs and sugars.
One of the most common food additives that are found in meal replacement shakes is maltodextrin — a starchy white powder that many manufacturers use to improve a food’s appearance, texture, and shelf life.
Corn and soy-based maltodextrins have been linked to high cholesterol, type 2 diabetes, and weight gain.
The problem with supplements is that it’s not required for a company to disclose this information on their product label unless it's a primary ingredient.
But, most companies don’t add maltodextrin directly to their formulations which is why you won’t often see it on a label. Instead of a primary ingredient, maltodextrin is used as a carrier ingredient for many superfoods when converting them to powders, making them easier to blend and extending their shelf life.
Meal replacement shake manufacturers will also use sugar alcohols like xylitol, erythritol, and allulose to make their products appear to be healthier than they really are and labeled as “sugar free”.
Research has found that many of these synthetic sugar replacers can be counterproductive to weight loss because they actually disrupt the healthy microorganisms in your gut — an essential component to all aspects of health.
The Smoothie Bowl Problem for Diabetics
If you’re a smoothie lover (like me) there’s another huge problem you need to consider when it comes to meal replacement shakes, which is the taste, mixability, and fullness factor.
The reality is that most meal replacement shakes don’t taste great.
The ones that do typically contain a ton of carbs and sugars because that’s what gives them their sweet taste. Which means that most people use the powder to create a more robust and better tasting breakfast smoothie or bowl.
However, if you’re using a typical meal replacement powder that is high in calories and carbs to create a smoothie recipe for your shake, you won’t be very successful with your weight loss goals.
This is because most meal replacement shakes are already very high in calories and in carbs/sugars. So, when you add oat milk, nut butter, and berries to your shake, you make the shake incredibly calorie dense.
This is a great option if you’re looking for a meal replacement shake to gain weight but not so great when you want to lose weight.
How can you lose weight if your smoothie bowl is 900 calories?
One solution is to simply never add anything to your shake.
But that means you better LOVE the taste and texture of whatever product you choose. It also needs to be free of artificial sweeteners and hidden chemical additives that actually cause the body to hold onto weight.
For anyone that’s done a decent amount of research into these products, there’s not a lot out there that actually meet the criteria above.
But all is not lost.
Our recommendation is to choose a meal replacement shake that’s low in calories and sugar like our Essentials Shake.
Now, obviously we’re biased, but can you really blame us?
When you do the side-by-side comparison you’ll see that nothing else compares to what the Essentials Shake provides.
And that’s because we chose a different path based on real nutritional research, not just the idea that more of something is automatically better.
As we’ve pointed out… more carbs, more sugar, more calories, and more maltodextrin-loaded superfoods are the last thing you need when it comes to enhancing your health.
And, the best part is, when you’re in the mood for something different, you can easily change the flavor and texture by creating a smoothie with a lot of fruit, plant-based milk, and nut butters and still lose weight.
This is because with the Essentials Shake, your total calories will likely be well under 500 kcal, helping you achieve the caloric deficit you’re after while still leaving plenty of room for eating whole food meals, not just guzzling all your meals in liquid form.
Meal Replacement Shakes for Weight Gain: The Better Choice?
If you’re trying to gain weight, and simply using the net-calorie surplus way of eating to get you there, then all meal replacement shakes are decent options.
That’s because most meal replacement shakes are high in protein, calories, and carbs and loaded with artificial ingredients and synthetic vitamins.
Everything you need to increase your weight.
The question remains, what type of weight are you looking to gain?
If your goal is to put on lean muscle mass, you’ll want to eat as clean as possible to avoid adding excess body fat.
That’s why when choosing a meal replacement shake for weight gain, it’s important to look beyond the calories and macronutrients and instead focus on the quality of ingredients.
You’re better off choosing a meal replacement powder with slightly lower calories but high quality nutrients because you can easily add milk, fruit, and fats to increase the caloric density of the shake.
Following this advice will ensure you gain the right type of weight and not simply pack on pounds of body fat
Why LyfeFuel Might Be Bad For Weight Gain
It might sound weird coming from us, but you can’t use LyfeFuel on its own to gain weight easily.
Sure, you’re getting enough protein and micronutrients, but you’re not getting enough calories living off shakes alone.
And coming from the perspective of a professional athlete — who literally had to consume massive amounts of calories — I understand how difficult it can be to meet your calorie needs when trying to gain weight.
So, I know how important liquid meals can be.
Just remember that it’s easier to add to your shake and customize it to your specific needs but impossible to remove bad ingredients and junk calories that are already in the powder itself.
So, if you’re trying to gain weight (muscle) while using LyfeFuel, make a delicious smoothie or bowl from one of our recipes – like the Mango Smoothie or the Banana Oat Bowl.
For packing on muscle and achieving peak performance, check out our Recovery Shake – a complete protein and superfood mix designed for athletes and more active individuals.
Did you know?
The recommended daily allowance (RDA) for protein is 0.8 grams per kg.
But most scientific studies recommend 0.8 grams to 1 gram per pound of your lean mass.
Which is more than 2x the RDA!

LyfeFuel’s Approach to Nutritionally Complete Shakes
Now, coming back to the crux of this article.
As we explained above, you want calories low and protein/micronutrients high.
Most meal replacement shakes are not doing this. They are high in calories and low in micronutrients or alternatively give you a cookie cutter formula of 33% of everything which won’t help to replenish the most important nutrients missing from modern diets.
So, let’s look at how we do things differently at LyfeFuel.
1. More Nutrient Dense Than Other Shakes
Nutrient Density is defined as the concentration of micronutrients (vitamins & minerals) in a given amount of food relative to the calories it contains.
Everyone knows that we should be eating more nutrient dense foods such as fruits and leafy vegetables but it’s not always easy or convenient to get these foods in modern diets. Not only that, but as we mentioned earlier, the fruits and vegetables you find at your local supermarket are not as nutrient dense as they used to be.
So, if we know we should be eating more whole fruits and vegetables for better health and optimal nutrition, why don’t we apply this same principle to meal replacement shakes?
Using this rationale, the best meal replacement shake would be the one that has the most micronutrients with the fewest amount of calories.
There is one problem with this however.
By this logic, the most nutrient dense food on the planet is a multivitamin. All micronutrients with zero calories.
But a multivitamin is not food. It’s not filling or satisfying.
And organic greens powders suffer from the same problem.
This is where protein comes in.
Protein is essential for our bodies and it is highly satiating. This means that it will keep you fuller for longer compared to carbohydrates. Another benefit of protein is the thermic effect that we discussed earlier. Which means you can eat more protein while not gaining much weight and even losing weight.
This is why LyfeFuel has 18g of complete protein along with all the essential micronutrients with just the right amount of calories.
So, if someone asks which is the most nutrient dense meal replacement shake in the market, then you know the answer.
2. Real Whole Foods Instead Of Synthetic Chemicals
Most meal replacement shakes use synthetic chemicals for their vitamins.
They’ll use compounds like Retinyl Acetate, Thiamin, Riboflavin, Niacinamide etc which are synthetic forms of vitamins A, B2, B3, B1.
These compounds are similar to micronutrients we get from foods like carrots, spinach, broccoli etc but they are made in a lab. This comes with significant disadvantages.
These synthetic compounds are fat soluble, and less bioavailable than their natural forms. Plus when you eat real food, you get enzymes that help you absorb nutrients better.
But LyfeFuel exclusively uses whole foods as a source of micronutrients. We use powdered forms of superfoods that allow you to get the micronutrients you need in the most natural form possible (for a meal replacement shake).
3. Designed to Fill the Gaps of Modern Diets
There are a few problems we need to discuss when it comes to meal replacement shakes and our diets.
This problem has become so common that the vast majority of Americans experience some form of vitamin deficiency or insufficiency.
The good news is, that based on the massive amounts of nutritional data collected from academic institutions we know exactly which nutrients are the most at risk in modern diets.
The problem with most meal replacement shakes is that they aren’t actually designed to compliment your diet from a micronutrient standpoint. Providing 10–30% of nutrients that you’re already getting in adequate amounts from food isn’t enough.
What the body needs is high amounts of the hard-to-get nutrients to restore metabolic function and enable the body to function optimally, which it simply cannot do when nutrition is lacking.
That’s why we designed LyfeFuel to fill the gaps of modern diets by giving you adequate amounts of micronutrients in the most natural form possible.
4. Diet Agnostic (Flexibility based on your goals)
LyfeFuel was designed to fit in just about any diet, except for maybe the carnivore diet.
It can most certainly be a powerful nutritional tool to support your overall wellness and compliment your diet.
That said, we don’t like the word diet because of what it has come to represent in modern society. These days you can put diet right up there with politics and religion… nobody can seem to agree on anything!
Let’s face it. The perfect diet doesn’t exist.
What works for one person can be wildly different than what works for another. It would be foolish and irresponsible for us to assume that the Essentials Shake is the perfect fit for everyone… it’s not. However, there is one underlying principle that should never be ignored.
And that’s food quality.
The highest quality foods are the ones found in nature, not synthetically created in a lab.
Following a diet that is rich in plant-based whole foods while avoiding chemicals, preservatives, and artificial ingredients is the best way to live a long and healthy life.
Whether you’re vegan, pescatarian, low carb, keto, or more of a locavore like me, LyfeFuel was created to support your health while giving you the essential nutrients you need to “Live Your Fullest Everyday” — something that we can all benefit from.
This is because we focus on creating optimal nutrition from real food using whole food synergy to deliver the protein and micronutrients you need rather than just carbs and fat that most of us get plenty of already.
LyfeFuel was developed to fit into your lifestyle rather than you trying to fit into ours. If you’re vegan, you can use nut milk. If you’re keto, you can add MCT oil. If you want to lose weight, use water. If you want to gain weight, make a smoothie.
Health is a lifelong journey and we’re here to support you every step of the way… one that is uniquely your own. Whether you’re a professional athlete training for your quest for gold or just trying to get back to feeling and looking great, we’ve got you covered.
It all starts with the quality of the fuel you put in your body and making a conscious choice about where your food and ingredients come from. Because it matters.
