Zero-carb protein powders have become increasingly popular among athletes, dieters, and health-conscious individuals. These supplements offer a concentrated source of protein without the added carbohydrates, making them ideal for specific dietary needs and fitness goals. This article delves into the benefits of zero-carb protein powders, particularly focusing on vegan options, and provides a comprehensive guide to their uses, advantages, and considerations.
Understanding Zero-Carb Protein Powders
Zero-carb protein powder is a specialized supplement designed to provide high-quality protein without any carbohydrates. It is composed primarily of plant-based proteins, making it suitable for vegans and those looking to reduce their carb intake. Common sources of plant-based proteins in zero-carb vegan protein powders include pea protein, hemp protein, and brown rice protein.
The Importance of Protein
Protein is a macronutrient vital for various bodily functions, including muscle repair, growth, and overall maintenance. Dietary protein is important for preventing lean body mass loss, promoting growth and repair of the body, and generally maintaining good health. Dietary protein may come from animal sources or plant-based foods. Protein is a major component of the skin, muscles, bones, organs, hair, and nails.
Macronutrient Balance
Fat, protein, and carbohydrates make up the three macronutrients present in food. It is important for a person to have a balanced diet and consume sufficient amounts of each macronutrient. However, if a person is looking to lose weight or alter their body composition, they may wish to adjust the balance of macronutrients and consume more protein while reducing their carbohydrate intake.
Dietary guidelines suggest the following carbohydrate and protein intake for male and female adults: To follow a low carb, high protein diet, a person would need to decrease their carb intake to about 26% of their total calories. The definition of a high protein intake varies among sources, but a 2020 study trialing a high protein diet defined it as 30% of a person’s total calorie intake.

Low-Carb, High-Protein Diets
Low carb, high protein diets restrict the consumption of carbohydrates while promoting the consumption of proteins. This type of diet may help weight loss and muscle building, but may also carry health risks.
Potential Benefits
A low carb, high protein diet may offer several benefits, including:
- Weight loss: There is some evidence to suggest that a low carb, high protein diet may facilitate weight loss. This is due in part to protein helping people feel fuller with less food. However, the results will vary depending on various factors, including calorie consumption and amount of exercise.
- Maintain weight loss: In addition to facilitating weight loss, a high protein diet may help people maintain a moderate body weight.
- Body Composition: Body composition refers to the percentage of fat, bone, water, and muscle in the human body. Research from 2017 suggests that diets high in protein may improve body composition.
- Blood Sugar: A 2019 study looking at a reduced carbohydrate, high protein diet for people with type 2 diabetes notes that this way of eating improved average glucose levels.
- Heart Disease: Low carbohydrate diets may have a beneficial effect on factors that contribute to heart disease. However, more research is necessary to establish the long-term effects of a low carb diet on heart health.
- Bone health: A 2019 meta-analysis highlights that eating more protein than the average recommended daily allowance can reduce the risk of hip fracture and loss of bone mineral density in older adults.
Potential Risks
Adopting a low carb, high protein diet may pose certain risks. For example, a diet that is high in protein can put acid load on the kidneys, which may increase a person’s risk of developing kidney disease.
An older review from 2013 suggests that the long-term consumption of a high protein diet may also contribute to the following health issues:
- bone disorders
- increased cancer risks
- problems with liver function
- coronary artery disease
A 2018 study notes that the type of protein that a person consumes on a low carb, high protein diet may affect mortality. Low carb diets that incorporate protein and fat from meats, such as chicken, pose a higher mortality risk than plant-based proteins and fats.
Foods to Include and Avoid
People following a low carb, high protein diet can include the following 14 foods in their meals:
- eggs
- fish and shellfish
- meat
- poultry
- certain dairy
- nonstarchy vegetables
- seeds
- soy
- mycoprotein
- kefir
- almonds, almond butter, and almond milk
- peanuts and peanut butter
- pistachios
- chickpeas
People who are trying to limit their carbohydrate intake may wish to avoid the following 7 types of foods:
- bread and grains
- starches
- sugary drinks
- processed high carb foods
- cereal
- certain alcohols
- juice
Types of Protein Powders
A person can also increase the amount of protein in their diet by taking supplements, although it is advisable to discuss this with a healthcare professional first. Protein supplements include:
- Whey isolate: Whey is a byproduct of milk, and it is often a core ingredient in protein shakes. Whey isolate has undergone a process to remove fats and carbs, leaving mostly protein. A person can mix whey isolate powder with milk or water.
- Vegan isolate powder: Products with vegan isolate powder often use pea or bean isolate. Similar to whey isolate, a person can mix vegan isolate powder with a plant-based milk or water.
- Protein bars: These are often a useful snack when on a low carb, high protein diet. However, a person should check the nutrients, as protein bars vary in the amount of carbs and protein they contain.
- Protein capsules: These are pills that contain protein powder. Depending on the manufacturer, the capsules may use different types of protein powder.
These are examples of protein supplements. Other types are also available, such as casein and soy.
Whey Protein
Whey protein refers to a group of eight proteins found in milk. These proteins, in order from the biggest to smallest amounts in milk, are:
- Beta-lactoglobulin.
- Alpha-lactalbumin.
- Glycomacropeptide.
- Immunoglobulins.
- Bovine serum albumin.
- Lactoferrin.
- Lactoperoxidase.
- Lysozyme.
Whey protein then undergoes another process to make one of three main types:
- Concentrate: Products with whey protein concentrate vary widely in their protein, lactose and fat content. Whey protein concentrate is in many protein drinks, bars and nutritional products. It’s also used in infant formula.
- Isolate: This type is consistently high in protein and low in fat or lactose. You may see it listed on the labels of protein supplements, such as bars and drinks. Whey protein isolate may be a suitable choice for people who are lactose intolerant - but don’t try any of these if you have a milk allergy.
- Hydrolysate: Also known as hydrolyzed whey protein, whey hydrolysate is the easiest to digest. It’s gentle on digestion because its long protein chains, called peptides, are pre-broken down into shorter ones. Specialized infant formulas often use hydrolyzed whey protein. You may also see it in medical supplements for nutritional deficiencies.
Whey protein is a complete protein, containing all nine essential amino acids.
Plant-Based Protein Powders
- Soy protein isolate: Soy protein powder is created by grinding soybeans into a meal and then into soy protein isolate, which is high in protein and very low in carbohydrates. Studies have shown that soy protein can be as effective for muscle protein synthesis as animal-based protein, including whey.
- Pea protein isolate: Like soy protein isolate, pea protein powder is made by grinding dried peas, which naturally contain protein, into a powder and extracting the carbs.
- Rice protein isolate: Rice protein powder is typically made by treating brown rice with enzymes that cause the carbs to separate from the proteins.
Choosing the Right Zero-Carb Protein Powder
Consider these important attributes before choosing a protein powder that will fit into your low carb or keto diet.
- Third-party testing: It’s important to choose only third-party tested protein powders to ensure the purity and potency of the product you choose. Look for NSF Certified for Sport and Informed Choice Certified products whenever possible.
- Total carb content: If you’re following a low carb or keto diet, total carbohydrate intake should be kept within a specific range based on the diet you’re following. Most protein powders will have less than 10 g of carbohydrates per serving, with many containing under 5 g.
- Protein source: Protein powders are made from many types of proteins. Some are single-source powders, while others are made from a blend of protein sources. Choose a protein powder made from a protein source that fits your dietary restrictions and preferences.
- Allergens: Some protein powders contain major allergens like milk, soy, tree nuts, or wheat. Read the labels carefully as you shop to ensure the protein powder you choose doesn’t contain an ingredient you need to avoid due to allergies.
- Cost: Protein powder costs vary widely, and the cost per serving should be considered when choosing the best option for you. This will also make sure that you choose a protein powder that’s financially sustainable, if you choose to take it for a long time.
Tips for Making Protein Powders More Palatable
If you spring for an unflavored animal- or plant-based protein powder, there are several ways to make them tastier while still staying within your daily carbohydrate range:
- Add small amounts of cocoa powder.
- Stir the powder into low carb beverages.
- Drizzle in sugar-free syrups.
- Spoon in artificial sweeteners like Splenda or natural sweeteners, including stevia or monk fruit extract.
- Use unflavored protein powders in baking.
- Stir in sugar-free, flavored pudding mixes.
- Add natural flavor extracts or spices, such as cinnamon.
