Our dietitians analyzed protein powders to support your weight loss goals. Transparent Labs, Ora Organic, and Naked Whey are among those that made the cut. See our full list.

In addition to reducing your overall calorie intake, increasing the amount of protein you consume may help you lose weight.

And protein powders are a convenient way to add more protein to your diet.

Specifically, they can:

  • Increase feelings of fullness: Protein helps you feel full longer, which can help you consume fewer calories.
  • Boost metabolism: Compared with carbs or fat, protein demands the most calories during digestion and utilization. Therefore, raising your protein intake can increase calorie burning.
  • Maintain lean muscle mass: When you lose weight, you might also lose fat and muscle. Consuming enough protein — alongside resistance training — can help you maintain muscle and prevent a decline in metabolism.

Our editors and dietitians reviewed more than 100 protein powders to determine the best protein powders for people trying to lose weight.

When shopping for a protein powder to support weight loss, be sure to consider the following factors:

  • Price: Protein powders vary significantly in price, depending on the brand, the protein type, and the presence of other ingredients. Be sure to consider the recurring monthly cost when determining which powder is right for your budget.
  • Protein type: Whether you choose whey, casein, or a plant-based source, the protein type doesn’t make a significant difference in terms of its effects on weight loss. Choose the type that best fits your dietary needs and preferences.
  • Quality testing: Because the Food and Drug Administration (FDA) doesn’t regulate supplements the same way as pharmaceuticals, it’s important to select a product from a reputable manufacturer. Look for a product that’s third-party tested to ensure that the contents match the label.
  • Additives: Protein powders commonly contain artificial sweeteners, flavors, and other additives to which you may be sensitive or intolerant. Carefully read a product’s ingredient list before purchasing to ensure that the product doesn’t contain an ingredient you need to avoid.
  • Taste: Protein powders vary greatly in terms of taste and texture, so you may need to try a few powders before finding a product and flavor that you enjoy. Keep in mind that protein powders containing artificial sweeteners or sugar alternatives, such as stevia, often have a slight aftertaste that some people dislike.

Protein powder can help increase overall protein intake, which can support weight loss, as it may help increase feelings of fullness, boost metabolism, and preserve lean muscle mass, even in a calorie deficit.

Specifically, whey protein has been shown to help increase fat loss and preserve lean muscle during weight loss efforts.

However, it’s important to integrate protein powder into a balanced diet and regular exercise routine for the best results.

Incorporating protein powder is an effective and convenient way to get in plenty of protein that can help you feel full and maintain muscle while eating in a calorie deficit.

Most protein powders can be blended into smoothies, mixed into oatmeal or yogurt, or even used in baking to increase the protein content of meals and snacks without significantly raising the calorie count.

You can use protein powder any time of day, but consuming it after workouts can aid in recovery and muscle maintenance and growth. This can be particularly beneficial if you’re interested in body recomposition, in which you not only lose weight but also build muscle.

Remember, protein powder can be a helpful component of a weight loss plan, but supplements should never replace the basics — balanced nutrition, sleep, stress management, and regular physical activity.

While there are several protein powder options, including whey and casein (which are made from cow’s milk) and plant-based options such as pea and hemp, one is not necessarily better for weight loss than others.

Some research suggests that whey protein may be better for preserving lean muscle mass during weight loss, but other research has shown that plant protein may offer similar benefits to whey.

Ultimately, the overall amount of protein appears to be the most important factor for weight loss.

Some protein powders are marketed to women, but they can be enjoyed by most healthy adults. Thus, there is no one kind of protein powder that is best for weight loss in women.

As mentioned above, whey protein may be desirable for protecting lean muscle mass during weight loss thanks to its higher leucine content, but many products can help women meet their protein needs when losing weight.

Protein powders can help you meet your target protein needs and support body recomposition, a process in which you gain muscle and lose fat at the same time. But keep in mind that resistance training or weightlifting is the primary driver of body recomposition.

It’s generally safe to use protein powder daily as part of a balanced diet. However, you should always choose high quality, third-party tested products to ensure safety and purity. And be sure to read the label thoroughly, as some products may contain additional ingredients that could be contraindicated for certain populations.

Many people use protein powders to build muscle, but these powders can also benefit your weight loss goals.

While these products may help you lose weight, you’ll get the best results if you use them alongside a balanced, reduced calorie diet and an exercise routine.
