Sometimes you don’t have time to prepare a meal—or you just don’t want to. And while we don’t recommend getting in the habit of drinking your meals instead of eating them, the best meal replacement shakes truly are complete, balanced meals all on their own, unlike the best protein powders which are typically focused on protein.

But as a category, meal replacement shakes are difficult to navigate. Manufacturers make a lot of health claims, but the ingredients in the shakes don’t always live up to the hype. To find the best meal replacement shakes, our GGR team, which is made up of certified personal trainers, certified nutrition coaches, and professional athletes, talked to registered dietitian Perry Nix, RD, LD, to get her take. We then spent several weeks testing various pre-made shakes and powders and rated them on several factors, including:
- Formulation: What are the macros? Are there other beneficial ingredients?
- Solubility: Does is dissolve fully in water or juice?
- Taste: Was it enjoyable? Would you drink it again?
- Price: Is the cost per serving worth it for most folks?
- Side effects: Does the shake lead to gas or other unwanted side effects?
- Customer service: Does the brand offer returns? Is it easy to contact customer support?
Our experts had to consider the above categories (plus a few more) and score each category on a scale of 1 to 5 stars using our supplement testing methodology. After we tallied up the results, these are the six options that made the cut.

Best Meal Replacement Shake Overall: Transparent Labs Mass Gainer
For: Those looking for a delicious meal replacement with a caloric surplus
Transparent Labs Mass Gainer is one of the more expensive mass gainer supplements, but it offers high-quality, naturally occurring, and clean ingredients that taste good.
What our tester says:
“There have been days where it’s saved me from accidentally intermittently fasting until dinner. It’s really the only weight gain powder I’ll use because I don’t like the idea of consuming 1,000 calories in one shake.”
Best-Tasting Meal Replacement Shake: Ka’Chava Shake
Good for: Anyone who wants a low- to moderate-calorie option with great taste and flavors
Ka’Chava is a plant-based meal replacement shake packed with vitamins, minerals, adaptogens, antioxidants, and super greens. Although there are five delicious flavors to choose from, it’s worth noting that the price per serving is over $4.
What our tester says:
“I don’t think the Chai flavor tastes exactly like Chai, but it’s pleasant nonetheless, and I appreciate that they offer more unique flavor options.”
Best Meal Replacement Shake for Weight Gain: HLTH Code Complete Meal
Good for: Those looking for a yummy shake with a thick consistency and a decent calorie content
HLTH Code Complete Meal contains 27 grams of protein per serving, a 1:1 ratio of healthy fats to protein, and up to 50% daily value of 25 vitamins and minerals. It is also available in a vegan plant-based version if you’d prefer. While we liked the taste, mixability was more of an issue.
What our tester says:
“These aren’t strong in your face with flavor, but I actually think that’s a good thing. If you’re going to be drinking these frequently, that’s better in my opinion.”
Best Gluten-Free Meal Replacement Shake: 310 All-in-One Meal Replacement Shake
Good for: Those who want an all-in-one shake that also has probiotics and adaptogens
If you’re looking for a meal replacement shake that is full of nutritional ingredients—including plant-based protein, adaptogens, and probiotics—310 shakes could be worth a try. They’re a bit light on calories and protein, but adding additional ingredients could make this a well-rounded option.
What our tester says:
“The chocolate, mocha, and vanilla flavors are great, and the clean ingredient list makes me continue to buy these. ”
Best Vegan Meal Replacement Shake: Huel Complete Black
Good for: Those who want a high-protein option with added vitamins and minerals
Huel Complete Protein Powder Black Edition is a nutritionally complete meal replacement shake powder, containing 400 calories per serving along with 40 grams of protein in all of the nine flavors.
What our tester says:
“The Cookies & Cream flavor is sweet, but not too sweet, and it dissolves pretty well for a meal replacement.”
Best Meal Replacement Shake for Weight Loss: Huel Ready-to-Drink
Good for: Anyone who prefers a grab-and-go drink that doesn’t require any mixing
Huel ready-to-drink is a great macro-balanced option for those who need a meal replacement on the go. Slow-release carbs keep you full and vitamins and minerals give you everything you need.
What our tester says:
“These have seriously become a lifesaver for me in terms of getting in all my calories during Ironman training, especially before early morning workouts when I just don’t want to eat yet.”
Other Meal Replacement Shakes We Tested
There are a number of meal replacement shakes on the market that didn’t make our list either from testing or research. Here are a few:
- Instant Knockout Complete: This one is a true meal replacement shake with 400 calories and a whopping 35 grams of protein per serving. But it didn’t score well for taste or solubility during testing, and these were really important to us.
- BOOST High-Protein Nutritional Drink: BOOST used to be the leader in meal replacement shakes, but so many better ones have come out since that we just can’t get on board with recommending this one. It has a bunch of added sugar and other low-quality ingredients, so we think you can do better.
- Shaklee Life Shake: This one has USDA organic ingredients, but it’s very low-calorie and doesn’t have enough other “perks” to justify a spot on the list. There are others that offer more complete nutrition along with antioxidants and other superfoods. Plus, these just don’t taste very good.
- Soylent Meal Replacement Shake: This shake got high marks during our testing. Frieda gave it a 4.5 out of 5 for taste and a 5 out of 5 for solubility, but ultimately the ingredients, namely the soy and sucralose, kept it from earning a top spot on the list.

What Are Meal Replacement Shakes?
Meal replacement shakes are premade shakes or powders that contain enough calories that they can serve as a meal for people who don’t have time to sit down and eat a full meal, such as those with long commutes or people constantly on the go. They are also used by bodybuilders who want an efficient way to drink more calories during their bulking phase, in which they’re looking to put on more size, or those trying to gain weight for health reasons.
While replacing your meal with a shake is OK every now and then, it’s important to prioritize whole foods on a day-to-day basis. Studies have shown that liquids, such as shakes, don’t promote satiety as much as foods that are chewed. Satiety is the feeling of being full, and can be impacted by things such as the texture of your food and how much space it takes up in your stomach. Things like fiber and protein content can also affect how satiated you feel after eating food or drinking a shake.

How We Tested the Best Meal Replacement Shakes
The GGR testing team, which is made up of certified personal trainers, certified nutrition coaches, and professional athletes, tested all of these meal replacements over a period of several weeks.
We made them exactly as recommended, usually by mixing them with water, milk, or a milk alternative, and also experimented with blending them with other ingredients. During our testing, we rated them on a variety of factors, which are outlined below.
Formulation
Formulation was a big consideration during testing. We analyzed protein, carb, and fat content, plus total calories per serving.
Because meal replacements are meant to replace an entire meal, it’s absolutely vital that they have ample amounts of both macronutrients (carbohydrates, protein, and fat) and micronutrients (vitamins and minerals). While many people just look at the protein and carbohydrate content, vitamins and minerals are essential nutrients, and falling short of your nutritional needs can greatly impact your overall health and wellness.
Because of this, we considered the entire nutritional profile and rated them based on the protein content and number of essential vitamins and minerals.

Calories
Meal replacement shakes should have enough calories to actually replace a meal. But they shouldn’t have so many calories that they start venturing into mass gainer territory (unless weight gain is your goal).
We considered 300 to 400 calories the sweet spot, but didn’t exclude a product based on this alone. If a meal replacement was lower in calories, we factored that into our scoring and called out that you might need to supplement it with other food.
RELATED: How Many Calories Should I Eat Per Day?
Taste
Taste is a subjective measure, but it’s an important one nonetheless. We rated this based on the opinions of our testers, but also on the general consensus in online customer reviews. We also factored in whether there was only one flavor or many to suit a variety of tastes.
Solubility
One of the biggest turnoffs of a meal replacement shake is a grainy texture. We factored in solubility as well as texture—was it super thick or thin?—into our scores.
In addition to these major factors, we also rated each shake on price, customer service and reviews, and transparency around testing and ingredients.
How to Choose the Best Meal Replacement Shake
When looking for a meal replacement shake that works for you, the first thing you need to look at are calories. You need to find a shake that has roughly the same amount of calories as a typical meal, with about 400 being the benchmark for most of the options we researched. Now, you can easily increase that number by either having a snack with it or if you’re using a powder by adding ingredients like milk.
Someone who’s 5 feet, 2 inches tall is going to need fewer calories in their shake than an active athlete who’s taller than 6 feet.

Secondly, look at the macronutrients, aka the fat, carbohydrates, protein. You’ll want to look for something with at least 20 grams of protein, which can help with satiety, and around 5-9 grams of fiber, which slows digestion to keep you full.
Consider the type of meal replacement shake. If you’re looking for something to down on your morning commute, a premade shake is the better choice. If you’re at home and just don’t want to cook, you might consider a powder.
Lastly, think about taste. Look at customer reviews or see if you can find a bottle at a store to see if you like the flavor before committing to buying several bottles.
Benefits of Meal Replacement Shakes
The biggest benefit of meal replacements is their convenience. Instead of spending time preparing a meal, sitting down to eat it, and cleaning up, you can just whip up a meal replacement shake and easily sip it, or take it with you on the way to work or the gym.
But they can have nutritional benefits, too—as long as you pick a good one. Some of the biggest health benefits of meal replacement shakes are:
- They’re high in protein. Most have at least 20 grams of protein per serving, which is about as much as protein powder.
- They contribute to daily fiber needs. Most people get about half the recommended fiber amount3 and meal replacement shakes can help you meet your needs. They usually have about 6 to 8 grams of fiber per serving, which is about 25% of the daily recommendation in one serving.
- They contain other essential vitamins and minerals. Most meal replacement shakes have added vitamins and minerals, so they offer balanced macronutrients and micronutrients.
- They often have other health-supporting ingredients, like prebiotics, probiotics, and adaptogens. Depending on the shake, you might get additional ingredients that contribute to your gut health and overall wellness.
- They may help you lose weight. Research shows that replacing some food calories with meal replacement shakes may contribute to greater weight loss4 compared to just restricting your calorie intake alone.
Third-Party Testing
When it comes to categorization, meal replacement shakes are kind of a gray area. Bottled meal replacement shakes are sold as a food product, while powders typically fall under the supplement category. Because of this, third-party testing and supplement regulations, like Current Good Manufacturing Practices (cGMP), aren’t applicable to all of them.
That being said, we researched the manufacturers we recommend to see what kind of guidelines they followed. If third-party testing was an option, most of them volunteered. There are also several on the list, like Ka’Chava, that maintain cGMP guidelines. When testing these meal replacement shakes, we took this into consideration as part of our scoring process.
Best Meal Replacement Shakes: FAQs
What is the best meal replacement shakes for weight loss?
The Huel Ready-to-Drink are our pick for the best meal replacement shake for weight loss. But in reality, any meal replacement shake that has ample protein, low to moderate calories, and little to no added sugar will work well in a weight loss or weight management plan. We don’t ever recommend replacing all your meals with shakes in the name of weight loss, though.
Is a meal replacement shake a good way to lose weight?
They can be. You have to make sure you’re in a calorie deficit and living a healthy lifestyle (exercising, eating plenty of veggies, and paying attention to your sleep schedule and stress levels) first and foremost. At the risk of sounding cliche, meal replacement shakes are meant to be one tool in your toolbox—not the sole answer to weight loss.
Is it OK to have a meal replacement shake every day?
Yes, it’s OK to drink meal replacement shakes every day, but they shouldn’t be the only thing you have. As a general rule, you can replace one to two meals per day with a meal replacement shake for a couple of weeks, but they’re not meant to be a long-term substitute for whole foods. And if your meal replacement shake is very low in calories, make sure you’re eating some other sources of quality calories and protein with it.
