We analyzed protein powders to support your weight loss goals. Optimum Nutrition, Muscle Milk, and Naked Whey made the cut.

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 stay fuller 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 may also lose fat and muscle. Consuming adequate protein — alongside resistance training — can help you maintain muscle and prevent a decline in metabolism.

We analyzed them all and put together this list of best protein powders for weight loss on the market today.

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, 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 (19).
  • Quality testing: As the FDA doesn’t regulate supplements the same way that it does 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. As such, carefully read the product’s ingredients list before purchasing to ensure it 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, like stevia, often have a slight aftertaste that some people dislike.

What type of protein powder is best for weight loss?

While there are several protein powders, like whey or casein, which are made from cow’s milk, or plant-based options like pea and hemp, one is not necessarily better for weight loss than others.

Some research suggests that whey protein may be superior in 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.

What is the best protein powder for weight loss in women?

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.

Can protein powder help you lose weight and gain muscle?

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

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

While these products can assist you in losing weight, you’ll get the best results if you use them alongside a balanced, reduced calorie diet and exercise routine.
