An excellent choice for purity and effectiveness. Minor drawback is the limited flavor options.

Every shake I make feels pure, and knowing I’m not downing unnecessary fillers makes every sip even more satisfying.

The only minor annoying thing for me is that not all flavor options are available in tubs.

Delicious and low in calories, ideal for taste-conscious dieters. More flavors would enhance its appeal.
Of all the plant-based and whey protein powders we researched, we couldn't find one that provided less than 90 calories per serving, considering the amount of protein. This makes My Protein Impact a standout choice in the market.
I remember the first time I mixed a shake with My Protein Impact; I was skeptical about the taste because of the low carb content. To my surprise, it was delicious! It became my go-to, especially on my strict low-calorie days.
I just found that I got a bit bored with the protein powder flavors available, so a few more whey protein isolate options would be great. Regardless, the flavors they have are decent and more natural-tasting than some protein powder brands.

This whey protein powder is not one of the absolute lowest-calorie protein powders out there, but it's still within range of losing weight and supporting most diets.

It's not only a low-calorie protein powder but also claims to help with filling you up for longer with its nutrient content.
The only thing I didn't like is that the protein powder seemed to be just a little bit grainy.
How We Tested the Products
We tested the products by curating a diverse list of low-calorie protein powders, ensuring a mix of popular brands, new entrants, and varied ingredient compositions. Our selection included products catering to different dietary preferences, including vegan, gluten-free, and dairy-free options.
- Nutritional value — Analyzing the protein content, type of protein used, and the presence of additional nutrients or additives.
- Taste and flavor — Assessing the taste profile, aftertaste, and the variety of flavors available.
- Mixability — Examining how well the powder mixes in different liquids to ensure a lump-free, smooth texture.
- Effectiveness — Monitoring the impact on muscle recovery, energy levels, and overall performance when incorporated into a regular diet and exercise routine.

- Quality and safety — We evaluated the quality of ingredients, manufacturing practices, and certifications to ensure each product met the highest standards of safety and quality.
Buyer’s Guide: Key Factors for Choosing the Best Low-Calorie Protein Powder
When shopping for the best low-calorie protein powder, consider these essential criteria:
- Protein content and quality. Check the protein content per serving. Opt for high-quality sources like whey isolate or plant-based proteins for more protein with fewer calories.
- Calorie count. Focus on the calorie count per serving. The best low-calorie powders provide substantial protein with minimal calories.
- Flavor and mixability. Taste matters, even in low-calorie options. Choose a flavor you like and a powder that mixes smoothly.
- Ingredient transparency. Look for powders with clear ingredient labels and avoid those with unnecessary fillers or additives that could increase calorie content.
These considerations will help you find a protein powder that meets your dietary goals, offering quality protein in a low-calorie package.
Who Are Low-Calorie Protein Powders Suitable For?
Low-calorie protein powders are suitable for people who have strict dietary needs in losing weight. But there are a few specific reasons that we’d like to go into a bit more.
Calorie-Restricted Diets
The secret to shedding some pounds is to eat healthy and burn more calories than you're taking in. It sounds simple, but it's not the easiest thing to do.
So, when you've managed to get your food cravings under control, the last thing you want is for your dietary supplement to mess things up for you.
Unfortunately, some of the commercial protein powder products out there that claim to be the best protein powder is laced with carbs, sugar, fat, and, ultimately, tons of calories.
Keto Lifestyle
The only way you can create low-calorie protein powders without reducing the protein content is by stripping out carbs and fat. This is especially interesting for anyone on the keto diet where carbs are basically the enemy.
Unless those carbs come in the form of dietary fiber, you want to keep them to an absolute minimum. Fiber doesn't only help you feel full longer, it also improves the body's digestive process.
Underlying Health Issues
I have worked with people who suffered from heart conditions that were ultimately diet-related. For such people, it's vital to remove all saturated and trans fats from everything they eat, even protein powders [2].
Based on the information I got from my dietitian, she always recommends low-calorie protein products as they generally limit or completely remove any fats.
But there's more to the protein powder story.
How Does Low-Calorie Protein Powder Help With Weight Loss?
Low-calorie protein powder helps with weight loss through appetite suppression and metabolic rate increase. Here's a more detailed breakdown.
Achieve Net Negative Calories
By using only the best low-calorie protein powder like those above, you may be able to lose weight faster as you will be taking in fewer calories. When that is combined with some more regular physical activity, things start to happen in the fat melting department.
Deal With Hunger Cravings
Usually, people look for fiber to feel full. But protein has this hidden benefit of taking longer to digest than carbs. As a result, it gives you the feeling of satiety for longer, which may help with skipping snacks and extended fasting periods [3].
So, if instead of reaching for a Krispy Kreme for your snack, you pick up a tasty flavored protein shake, you might be able to make some more significant changes in your lifestyle.
For instance, protein has been shown to reduce appetite and prevent overeating by triggering hormones that promote feelings of fullness and satisfaction.
- Franziska Spritzler, Registered Dietitian
Boost Metabolic Rates
One of the biggest obstacles people have in their battle in losing weight is how their metabolism reacts to certain macronutrients. For so many of my clients, it's almost always down to refined carbohydrates.
The good news is that protein has been shown in clinical research to boost metabolic rates that may help with burning more fat [4] .
Check out these helpful tips to learn more ...
Bottom line: eating more protein can boost your metabolism because it has a higher thermic effect meaning your body is going to have to work harder to digest, break down, and store it.
- Tamara Pridgett, Personal Trainer
What Should Influence Your Protein Powder Buying Decision?
These are the four areas that should influence your buying decision when it comes to low-calorie protein powders:
- Protein sources. Choose between plant-based (like pea, hemp, and brown rice) and animal-based (like whey, beef, chicken, eggs) proteins. For complete amino acids, mix plant proteins, like rice and pea. Whey is great for its branched-chain amino acids. Choosing the best protein powder is almost an entirely personal choice. Whether it's vegetable pea protein isolate or whey protein powder, the more important thing is that you're getting the recommended amount for your goal.
- Muscle building goals. If you're not vegan and aiming for muscle growth, go for high-quality whey protein. It's packed with all nine essential amino acids, including BCAAs. Vegans can combine rice, hemp, and pea proteins for similar benefits [5].
- Dietary restrictions. You might be thinking of vegans and vegetarians where it's down to a personal choice. But it's far more common to make dietary decisions due to allergies and intolerances [6]. Avoid lactose, soy, or gluten if necessary and watch out for caffeine in some powders.
- Texture and taste. Texture has improved, but it's still about trial and error. Check online reviews to find a powder that blends smoothly and tastes good.
- Safety and quality. Be cautious of over-hyped brands. Look for third-party testing or purity certifications for quality assurance. Always talk to a doctor before adding supplements to your routine.
- Types of protein powders: Understand different types: concentrates (60-80% protein), isolates (90-95% protein, low fat/carbs), hydrolysates (pre-digested for easy absorption), and egg protein (slow-absorbing, lactose-free).
Your choice of protein powder is personal, focusing on your goals, dietary needs, and taste preferences.
Speaking of, here are some of the best protein powders tailored for every goal:
How To Use Low-Calorie Protein Powder To Lose Weight?
To lose weight, you should use a low-calorie protein powder following these three simple guidelines that I often give to my clients.
Balance Your Diet First
You have to fix your diet and start counting calories. Trash all the processed stuff and everything laced with sugar. The easiest way to achieve this is with an app like Noom to help you monitor your macros and calories.
Create A Regular Exercise Routine
You have to start doing physical activity several times a day. No, I don't mean going to the gym twice a day. Even a 10-minute fast-paced walk at lunchtime may help to burn some extra calories.
Know How to Mix the Protein Powders
Here are various mixing options that enhance taste and texture without packing on extra calories:
- Water — Is the most straightforward mixing option. It keeps the calorie count low and delivers the protein in its purest form. However, the taste can be somewhat bland. To spice it up, consider adding a dash of cinnamon or a drop of vanilla extract to infuse flavor without adding significant calories.
- Coffee — Mix your protein powder with cold coffee to add a robust flavor and an energy boost. It’s a perfect post-morning workout drink that combines the benefits of protein and caffeine, helping you recover while staying alert and focused.
- Skim milk — Adds a creamy texture to your protein shake without the added fats. It also provides additional calcium and vitamin D, supporting bone health.
- Plant-based milk — Almond, soy, and oat milk are excellent alternatives for those seeking plant-based options. Each adds a unique flavor profile and consistency to your protein shake. Almond milk is light and nutty, soy milk is rich and creamy, and oat milk boasts a sweet, mild taste.
- Fruits and berries — Add natural sweetness, vibrant colors, and a variety of textures. Berries are low in calories but high in antioxidants, making them a healthy choice. Bananas can add creaminess, while citrus fruits offer a refreshing tang.
Stack With Other Supplements
People often think of bodybuilders who stack multiple different protein supplements to build muscle mass. However, there are some great pre-workout products and fat burners that may help you work harder.
And if all else fails, invest some money by hiring a personal trainer like me to hold you accountable 😉

My friends and I are doing a challenge this week, since we’re all in quarantine, we are doing a fitness challenge and whoever loses the most weight during this quarantine period wins. This is going to be a hard one since I already gained 3 lbs the past 3 days LOL but I’m determined! I looked at these products and they got me very interested. I havent tried many but im surprise the ones on this list are very affordable, not sure what the average cost is
I have a question regarding this topic, I am on keto diet, and I am looking for something that I can use for my work out. I have been using this brand from my local grocery and it’s okay, except that it is very high in sugars and goes against what I am trying to achieve with my diet.

Looking forward to finally having something that’s zero carbn
I have been using trans parent labs for many years and I always go back to it when i need some support for my gym efforts. i have to say that it’s one of my favorites!
Anyway, thank you for putting up this article, you’re always on the loop when it comes to things like these. Good stuff!
Almost everyone takes supplements nowadays. They have become part of our daily diet, and the industry is huge to say the least. Yes, these companies earn billions of dollars. I personally think that everyone needs them especially with all the unnatural foods we have now! Fast food here, fast food there, fast food everywhere. As much as we want to eat healthy, it can be difficult to do that when everything is already processed. The only way to go about it is to supplement so we get all the things we need in our bodies and make sure that we’re all healthy and safe all the time!
how i wish we can still be at a time where every thing we need is right in the backyard. I remember living at my grand mother’s home and she had chilis, tomatoes, onions, garlics and some leaves in her garden –we can just pick something if we need it! for free! good times. anyway, I live in a condo now and I don’t have a garden so the farmer’s market is my friend when it comes to condiments and cooking stuff.
I have always used the 7th brand on this list and i thought it was the lowest i could find…didn’t know there were zero in some of these brands!! so crazy. i have to get one of these next time.
thank you for always taking time to review these things, really helpful stuff!!! my friend shared one of your reviews before and here I am, addicted to your content. i always read your content and 100% of the time, i learn something new. I love your style, and my friend and I always discuss about your recommendations! i also like the exercise tips and diet advise, makes me more conscious about my heath
“Over thousands of years, one generation has passed its “survival genes” on to the next. So thanks to our ancestors, we are equipped to subsist on minuscule amounts of the essential nutrients, just in case a famine comes along. But as I said before, this insurance policy remains effective only into our twenties — just long enough for us to reproduce. It includes no provision for aging.”
this one is from chiro dot org, do you agree? I do! We are able to survive with the least amount of nutrients for as long our bodies can handle! But this doesn’t mean you have to starve, just eat healthy, make sure you get enough sleep, and you’ll be fine
Love this article! I”m looking for one for my dad — he has diabetes and wants to start going to the gym, asked his dietitian if he can go have some of these and he agreed, as long as it is low in calori e. this is perfect!!! the top product with zero car bs is awesome!! Excited for him to try that stuff. He has got a personal trainer who will help him with the work outs and his dietitian from the hospital will plan his meals. I am sure he will be in his best shape in no time. Love you daddddd
This article is very useful and informative. The product mentioned in this article is awesome and has no carbs.

You give really good advice on which product one should use. I am extremely grateful for your advice.
I have been looking for something that can help me with muscle building. The recommendations are perfect for me!!
Most of the suggestions are actually all natural. I find that very attractive.
