There’s so much more to getting fit than just working out. You can lift every day, and you can do cardio constantly, but you’ll never really reach your full potential until you address what you’re putting into your body, too. And the best weight protein for weight loss is one of the best things you can put into your body.

Whey protein is a near magical substance for athletes and fitness enthusiasts. It helps eliminate body fat, build lean muscle mass and increase strength. It’s also known to lower blood pressure and blood sugar, and even to have a positive impact on depression.

Because whey protein is so effective at helping reach fitness goals, the market is flooded with products. How can you choose the best whey protein for weight loss from among these many options? Here’s a look at the best of the best.

Whey protein powder is incredibly beneficial … for those who are working out regularly. It’s not something that you can just take in the morning, sit on the couch all day, and then see muscle-gaining, waist-slimming benefits out of. Make sure you read our Buyer’s Guide at the bottom of this page to make sure that whey protein powder is for you before you jump in and buy a 5-pound tub.

Also, for comparison’s sake and uniformity, we rated only the 5-pound versions of each of the products on this page. But, if you’re new to whey protein powder, you might want to try a smaller size first. This will let you get to know a product without making a large upfront investment. You’ll get a sense of its flavor, its texture and how it helps you build lean muscle mass while dropping fat.

2. ALLMAX Pure Whey Protein Blend

ALLMAX Pure Whey Protein Blend comes within a whisker of taking the top spot in this review. It has so much to offer, including one of the best price points, a great taste, easy blending and an incredibly handy scoop — which shouldn’t be underrated. As with any review that we write, our top pick isn’t going to be the best option for all readers.

So take account of your unique needs and desires when searching for the best whey protein for weight loss, and you may find that ALLMAX Pure Whey Protein Blend is the best option for you. As mentioned, it came so close to being our top pick — it just came up short for one reason. Read one to find out what that reason is.

Chocolate, Chocolate Peanut Butter, Cookies & Cream, Strawberry, Vanilla
When you’re looking to use whey protein for weight loss, the last thing you want are unneeded calories. But, as you’ll see below, ALLMAX Pure Whey Protein Blend is on the high end of calorie content among the options on this page.

Great Taste, Easy Blend

ALLMAX Pure Whey Protein Blend checks the right boxes for workout enthusiasts looking for a well-rounded protein supplement. It provides the whey protein they want while also tasting great and mixing easily.

As you’ll see below, ALLMAX Pure Whey Protein Blend does have one drawback that prevents it from being the best whey protein for weight loss, but it’s attractive price point, great taste, ease of use and blending, plus other benefits, make it one of the best options on the market. If you’re trying multiple whey protein powders in search for the best one for your unique needs, it’s certainly worth a try.

An Incredibly Handy Scoop

Ease of use may not be the foremost priority when searching for the best whey protein for weight loss, but it’s certainly a factor — and ALLMAX Pure Whey Protein Blend may be the easiest protein powder to use thanks to its handy scoop.

The powder scoop latches right onto the lip of the container, which means it doesn’t just live down among the powder itself. This is great for many users who don’t want to reach a grimy post-workout hand down into their protein powder to fish out the scoop. Again, in the long run this is a small thing, but it’s one aspect of ALLMAX Pure Whey Protein Blend that users rave about.

High in Calorie Content

The lowest calorie content options include about 120 calories per serving. ALLMAX Pure Whey Protein Blend includes 170 calories per serving. While this may not sound like a huge jump, it’s significant when you’re on the hunt for the best whey protein for weight loss. A whey protein that includes 170 calories per serving is just about the most you’ll find.

The one big knock on ALLMAX Pure Whey Protein Blend is that it’s high in calories when compared to other options. But, if you’re willing to look past that one drawback, this is an affordable and effective whey protein powder that is among your best options.

Pros and Cons of ALLMAX Pure Whey Protein Blend

Pros of ALLMAX Pure Whey Protein Blend:

  • Nice blend of quality and price
  • Smooth mixing
  • Scoop promotes clean and easy use

Cons of ALLMAX Pure Whey Protein Blend:

  • More sugar than some alternatives
  • A little higher in calories
  • Not 100% pure protein


3. NAKED Grass Fed Whey Protein Powder

Whey protein is just about the purest, highest quality protein you can find. That’s one of the reasons why it’s so popular with workout warriors. That’s why it’s so concerning when you see some whey protein powders that include a multitude of other ingredients. Why are they needed?

NAKED Grass Fed Whey Protein Powder gives you access to the pure protein you want without the long list of head-scratching additives. When you want something that’s all-natural and that gives you a clean boost of protein, it’s hard to beat this option.

Does it have its shortcomings? Sure, and we describe them below. But this is a whey protein powder product that is fully aligned with the concept and philosophy of using whey protein as an all-natural, incredibly healthy, absolutely beneficial weight loser and muscle gainer.

Chocolate, Vanilla, Strawberry, Unflavored
While you can often find much better flash deals on Amazon and through other sellers, the MSRP on this 5-pound tub of whey protein is a jaw-dropper — especially when compared to alternatives on this page. You do get 76 servings out of the tub, which is more than others, but consider trying a smaller size to ensure you like the flavor and consistency before making the larger investment.

A Truly Natural Product

The NAKED name truly means something here: This is an all-natural product that only includes whey protein. When you look at the labels on other products, you’ll find that many include 20 ingredients or more, and you end up wondering why an ostensibly natural product would need so many additives.

When you choose a natural product, though, you may find that you sacrifice in some other areas. Below, you’ll discover that the flavor isn’t all that great, and that this product can be tough to blend and tough to handle. Maybe those additives in other products make them taste better and blend more easily?

Poor Taste, Poor Consistency

Look, you’re not going to get a whey protein powder for taste alone. Are you? Well, if you are, you can find plenty of other options that are going to blow this one out of the park. You wouldn’t expect much flavor from the unflavored option, but even the chocolate, strawberry and vanilla options are going to leave you wanting more on the taste front.

The consistency isn’t great either. NAKED Grass Fed Whey Protein powder is so light and thin that it’s difficult to mix well. The result is a foamy concoction that can be difficult to choke down. You’ll need to spend a bit of extra time shaking out the clumps. The result of the foamy mixture is that it aerates and expands during blending. You end up with a lot more drinking to do in order to get all your protein down, and it can leave you feeling bloated and gassy.

Tough to Handle

As mentioned, the NAKED powder itself is light and thin, and it will get absolutely everywhere if you’re not careful. It’s always a good idea to pour your water (or other liquid) before you add your protein so that you don’t end up with a huge cloud of whey. This shouldn’t necessarily be a deal-breaker for anyone, but it’s certainly an inconvenience — especially if you’re trying to mix and chug on the go.

NAKED Grass Fed Whey Protein Powder isn’t the least expensive or best tasting or easiest to handle product on the market. But it does have one thing going for it that many other products do not: it is truly all-natural. If you’re the type of fitness fanatic who only wants to put all-natural products inside your body, you may be willing to overlook NAKED’s shortcomings in exchange for this one major benefit.

Pros and Cons of NAKED Grass Fed Whey Protein Powder

Pros of NAKED Grass Fed Whey Protein Powder:

  • Light, pure and easily digestible
  • Easy on the stomach if you’re lactose intolerant
  • All natural

Cons of NAKED Grass Fed Whey Protein Powder:

  • Difficult to mix without a blender
  • Foamy and tough to dissolve
  • Weak on taste


4. PROMIX Grass-Fed Whey Protein

Everyone’s going to have a different focus when looking for a whey protein powder. You may be most interested in price and value: How much can you get for how little? You may be most interested in an all-natural product that includes whey protein and little else. Or you may be interested in a whey protein that easy to use and easy to blend or mix.

PROMIX Grass-Fed Whey Protein is among the most well-rounded products you’ll find when it comes to checking all of these boxes. You can find other products that beat it in certain areas or aspects, but this is one of the most complete solutions on the market.

The taste is good. The blending is fast and easy (though the bag is tough to close). And the products are all natural. The price tag may be the one area where PROMIX Grass-Fed Whey Protein falls short, but you can often find price-slashing deals on Amazon and similar websites. It’s the price tag that holds this option back from being our top pick, but that’s not to say it won’t be the best whey protein for weight loss option for some users.

Chocolate, Vanilla, Unflavored
Whey protein users often want their products to be as easy to use as possible. One of the strange quirks about PROMIX Grass-Fed Whey Protein is that the interior bag is difficult to close. You can spend precious time trying to seal the Ziploc-style bag, but it’s going to be far easier just to grab a clothespin or similar clip to seal off the product.

All Natural, Limited Ingredients

PROMIX Grass-Fed Why Protein is another option that is all natural and that includes a small number of ingredients. Look at the label and you’ll find that it’s made up of only whey protein and sunflower lecithin.

PROMIX also owns a track record of using only the best of the best in its ingredients. It also conducts comprehensive tests to ensure that its products meet the highest quality standards and that there are no hormones or heavy metals present.

Perhaps because of its all-natural recipe and testing, this product delivers results while also going easy on your stomach. If you’ve ever experienced gastrointestinal issues related to whey protein or other supplements, you’ll find that PROMIX offers relatively painless digestion.

Nice Flavor, Easy Blending

Some whey protein powders go overboard with their flavors, making them so sweet as to be almost undrinkable. Others offer chocolate, strawberry and other flavors, but the flavors themselves are nearly undetectable. That’s not the case with PROMIX Grass-Fed Whey Protein, which offers three flavors that are just tasty enough to help the concoction go down without being overly sweet.

PROMIX Grass-Fed Whey Protein also blends easily into your drink or smoothie of choice. It’s not so thin or light as to fly all over the place, and it doesn’t clump together either. All in all, this is a nice-tasting, easy-blending option when you want an all-natural whey protein powder that helps you get results.

Large Servings, Large Price

This is absolutely an attractive option when you look at the product itself. But, when you consider the price tag and how many servings you get out of one unit, the perceived value of PROMIX Grass-Fed Whey Protein begins to shrink.

The MSRP is staggering compared to other products on this page. Of course, you can always look for better deals on Amazon and through other retailers. A better deal would greatly increase the value. But remember also that not all 5-pound whey protein products are created equal. Look at how many servings you get out of each tub, too, and you’ll find that some 5-pound tubs have a lot more inside than others.

For example, PROMIX offers about 15 fewer servings than you’ll get with NAKED. That’s about a 20 percent drop, which affects value as well.

PROMIX is a relative newcomer to the whey protein powder market, but it’s quickly proving itself as one of your best bets for all-natural products. It’s not 100% organic, but it’s one of the cleanest and simplest formulas you’ll find. Yes, the price is higher than many other options, but what you’re paying for is quality — and results for your time spent in the gym.

Pros and Cons of PROMIX Grass-Fed Whey Protein

Pros of PROMIX Grass-Fed Whey Protein:

  • Great texture and taste
  • Non-GMO ingredients
  • Easy to blend into your drink or smoothie or choice

Cons of PROMIX Grass-Fed Whey Protein:

  • Package is tough to close after initial opening
  • Not 100% organic
  • Most expensive MSRP


5. EAS 100% Pure Whey Protein Powder

Here’s a value option for the price-conscious workout warrior. EAS 100% Pure Whey Protein Powder is available at a rock-bottom price, but it’s better than bottom-of-market when it comes to performance. In fact, EAS 100% Pure Protein Powder packs a ton of protein into each serving. That’s nice when you’re already paying a hefty gym membership bill, not to mention all of the other day-to-day costs and bills in your life.

This product certainly has its drawbacks, including the presence of more fat, carbs and calories than you’ll find in other products. But it’s certainly an attractive option for those who want to get a ton of protein without paying exorbitant prices. There’s a reason whey EAS 100% Pure Whey Protein Powder isn’t our top pick (read on to learn more), but it can certainly be the best option for some users. Read as much as you can about each product, and choose the one that best meets your unique needs.

Vanilla, Chocolate, Strawberry
Unfortunately, it’s not just the fat, calorie and carbs that give some users pause about snagging a tub of EAS 100% Whey Protein Powder. It’s also the presence of heavy metals and the absence of digestive enzymes. These are no doubt shortcuts that make the low price point possible, but know going in that this is not some sort of all-natural, organic product that includes only whey protein.

Great Taste With High Protein Content

Not everyone is good at choking down a protein drink of shake. EAS 100% Pure Whey Protein Powder makes ingesting your supplements easy. Choose from among vanilla, chocolate and strawberry options, each of which delivers just enough taste without being overly sweet.

EAS 100% Pure Whey Protein Powder also delivers an incredible amount of protein. As noted below, it also includes a little more in the way of fat and carbs than other options, but some may be willing to make the trade-off for more protein and great taste.

Strong Price Point

No, EAS 100% Pure Whey Protein Powder isn’t all-natural, but it’s available at a fraction of the cost of what you’ll pay for an all-natural option. This may or may not be an important factor for you, but we’re talking about significant savings over the long-term. You’re getting high protein content, great taste and a great price, while you’ll sacrifice in other areas — like limited ingredients, fat content, calorie content and more.

Higher in Fat and Carbs

Many fitness enthusiasts are concerned about EAS 100% Pure Whey Protein Powder, not just because of its high fat, carb and calorie content, but more because of its list of ingredients. You’ll find salt, acesulfame potassium, sucralose, xanthan gum and other hard-to-pronounce additives. Are they harmless? Most likely. But many who workout are incredibly mindful of what they put in their bodies, and they would much prefer to pay a little bit more for a powder that includes whey protein and little else.

If you’re trying out different whey protein powders before committing to just one, EAS 100% Pure Protein Powder deserves to be in your rotation. Given its attractive price point, its great taste and its high protein content, this could be the ideal value option for you — if you’re willing to sacrifice in a few other areas.

Pros and Cons of EAS 100% Pure Whey Protein Powder

Pros of EAS 100% Pure Whey Protein Powder:

  • Rock-bottom pricing
  • High protein content per serving
  • Great taste

Cons of EAS 100% Pure Whey Protein Powder:

  • Too much fat content compared to alternatives
  • Some have criticized for presence of heavy metals
  • Lack of digestive enzymes


Buyer’s Guide

The best whey protein for weight loss for you may not be the best whey protein for weight loss for someone else. You must decide what factors are most important when searching for your perfect product. What are some of the factors you should consider? Take a look and learn more about the key decision points you need to take into account.

We said right at the top that whey protein is a growth market that’s being flooded with options. Not all of these options are created equal, and some will have advantages and benefits that others do not. Here’s a look at how to sort through this saturated market to find your best option for whey protein for weight loss.

How to Find Your Best Option

There’s so much information to take into account when searching for the best whey protein powder for weight loss. Here’s a look at 5 key considerations when you start your search for the perfect product to meet your needs:

Protein Powder vs. Mass Gainer

Make sure you don’t mistake a mass gainer for protein powder. The two different types of products deliver different results, and the best protein powder for weight loss will help you drop pounds a lot better than a mass gainer.

Mass gainer includes protein but also fats, carbohydrates and more calories. How many more calories? About 10 times as many.

Conversely, whey protein is known to help build lean muscle while also increasing endurance and stamina. If you’re looking to get in the best shape of your life, whey protein is the way to go. If you’re more interested in getting huge, go for the mass gainer.

Look for Fewer and More Natural Ingredients

Make sure to look at the ingredients in any product you consider. You want something that has fewer ingredients (protein and perhaps some flavoring) rather than one that has a wide range of additives. Also, the more natural a whey protein powder, the better.

Buy From Proven Manufacturers

No matter what you’re shopping for, it’s always a good idea to look to trusted brands that have long track records of serving highly satisfied customers. As mentioned, whey protein is a popular product, and tons of manufacturers are trying to jump into the game. Not all of them know exactly what they’re doing, so err on the side of choosing products from well-known, highly trusted brands.

Whey vs. Casein

You’ll find two main types of protein powders, and they are definitely not created equal. Whey protein is popular because it’s fast absorbing, while casein protein is digested much more slowly. There is a time and place for casein protein, such as right before bed. But whey protein is what you’re looking for in a post-workout supplement that’s going to help you lose weight and develop lean muscle.

Find Something That Agrees With Your Stomach

Not all whey protein powders agree with all stomachs. This is especially true if you have diabetes or gastrointestinal or kidney issues. We’ve tried to include as much information as possible on the recommended products and how they affect stomachs, but it might be a good idea to get a smaller container to start with. This will let you test out a product and see how it affects your stomach before going for the 5-pound size.

Frequently Asked Questions

What are the side effects of using whey protein?
You’ll be glad to know that there’s really only one side effect: lean muscle growth. When you take whey protein (in powder form or otherwise), the protein is either stored in the body or used to build muscle mass. That’s why it’s best to use when you’re engaged in a regular workout routine — you definitely want that protein put toward muscle mass rather than placed in storage.

Other than that, there are no significant side effects to worry about.

Is whey protein “paleo”?
If you’re on a paleo diet, you should be eliminating all dairy from your diet. Whey protein is a milk extract, which makes it inappropriate for anyone who’s going paleo.
Does whey protein stunt growth?
This is a common question among those 18 and under (or perhaps among those buying whey protein for teenagers). The answer is “no,” whey protein does not stunt growth. Just the opposite, actually, as it should lead to muscle growth.

Making the Most of Your Investment in the Best Whey Protein for Weight Loss

Whey protein is certainly an investment, but it’s one that will certainly pay off if used appropriately. Make sure you’re getting the most out of your whey protein by following these three simple guidelines:

  • Find the best product for you
  • Use it at the right time
  • Don’t overdo it

Not all whey protein is creating equal. Learn as much as you can about the best products on the market, and choose the one that best fits your unique needs. Then make sure you’re taking it at the right time — typically post-workout to help with recovery. And make sure you’re not overdoing it. Taking too much whey protein can reduce the benefits.

Final Thoughts on Finding the Best Whey Protein for Weight Loss

Are you still sitting on the fence about whether or not you should try whey protein for weight loss? Let’s be clear on one thing: If you’re serious about developing lean muscle mass and reaching your peak fitness level, a supplement like whey protein can be invaluable.

We mentioned that these products are available in sizes smaller than 5 pounds. You should absolutely try one of these smaller sizes and experience what it’s like to include whey protein into your diet. Just don’t expect results in a matter of days. As with any supplement, the true benefits won’t be evident for weeks, or more like months, in the long run.
