Whey Protein For Weight Loss: Benefits, How To Use & More In 2024

There is more than one way to lose weight. However, a weight loss method does not work without proper adjustments to your diet. Still, most weight loss methods usually involve supplements to enhance the changes made in diet and support the body as it burns off excess weight. 

One very popular supplement is whey protein, which commonly comes as a powder. There are many reasons why protein is important for weight loss and whey protein has all of those properties as well. 

Beyond its reputation as a muscle-building supplement, whey protein has gained recognition for its potential impact on weight management. This article aims to delve into the topic of whey protein for weight loss, exploring its benefits and providing guidance on how to incorporate it effectively into a weight loss routine.

Whey Protein Benefits For Weight Loss

Protein is a macronutrient with many benefits. Macronutrients are nutrients that your body needs in large quantities. The three major macronutrient classes are carbohydrates, proteins, and fats.

Proteins have numerous benefits such as preserving muscle mass and helping you feel satisfied after a meal. When it comes to weight management, protein is your best friend. By including an adequate amount of protein in your diet, you can increase your weight loss success.

But what are the benefits of whey protein for weight loss? Derived from milk during the cheese-making process, whey is a great source of protein. It all begins with milk undergoing pasteurization and the introduction of enzymes or acids to induce curdling. 

This action separates the milk into curds and the liquid whey. Curds are used to make cheese, and liquid whey — containing proteins, essential amino acids, vitamins, and minerals — undergoes a series of filtration methods to remove fats and carbohydrates. This leaves behind a concentrated liquid whey solution.

Whey protein is available in powdered form, making it convenient and easy to incorporate into your protein shakes and more. So, why is whey protein good for weight loss? Here are some benefits:

Increased Satiety

High protein foods are notorious for their appetite control because they help you feel full and satisfied. So whey protein, which is a high-quality protein, can keep you fuller for longer and reduce overall calorie intake.  It does this by sending signals to your brain that you’re good to go for a while. 

Whey protein increases the production of glucagon-like peptide-1 which stimulates the satiety hormone,^[1] so you feel fuller for longer. So, drinking whey protein supplements can help you get past a craving. 

Low In Calories

The best way to lose body fat is to cut down on how many calories you eat. You should find low-calorie options of certain meals as alternatives. 

Whey protein is quite low in calories,^[2] at only 87 calories per scoop. This low-calorie protein powder can be taken before or after your workout. Maintaining a caloric deficit is important for losing weight. 

Promotion Of Lean Muscle Mass

Another factor that is important for you to lose weight is promoting lean muscle mass.^[3] Lean muscle tissue is more metabolically active than fat tissue. This means that even at rest, muscle burns more calories than fat. 

With a higher metabolic rate, your body becomes more efficient at burning calories, which can aid in weight loss or weight maintenance. The leucine content in whey protein also triggers protein synthesis in muscle, helping you with muscle growth and maintenance.

Nutrient-Packed 

Aside from being primarily protein, whey protein has other important nutrients as well. It contains calcium, iron, potassium, and sodium. Individually, these nutrients have benefits they confer on the body. 

For example, calcium burns fat in the body, and research shows that it is helpful for weight loss. Specifically, it has been demonstrated that each 300 mg increment in regular calcium intake^[4] is associated with approximately 2.5–3.0 kg lower body weight in adults.

Whey protein concentrate also has benefits for cancer patients as research^[5] shows.

Boosts Metabolism And Fat-burning

Proteins, including whey, can boost your metabolism^[6] due to the thermic effect of food.^[7] When you consume protein, your body kicks into high gear to break it down and process it. Protein  digestion demands more energy than handling carbs or fats. 

So whey protein boosts metabolism by revving up your calorie expenditure, which translates into more calories burned, helping you inch closer to your fat-burning goals. Research^[8] shows this is more effective alongside resistance training in a weight loss program. It also helps that whey protein is low in fat at only 1.2 grams per scoop.^[2]

Best Time To Take Whey Protein For Weight Loss

To maximize the weight loss benefits of whey protein, it’s ideal to consume it between meals. This strategy can potentially trigger the release of hormones^[10] like glucagon-like peptide-1, peptide YY, and cholecystokinin, known for reducing appetite.

Incorporating a protein-rich snack between meals might lead to a decreased calorie intake later in the day. For instance, research^[11] showed that individuals who had a high-protein snack in the afternoon consumed around 100 fewer calories at dinner than those who opted for crackers or chocolate as their afternoon snack, despite all snacks providing the same number of calories.

So, the best time to take whey protein for weight loss is in between your daily meals and snacks. This approach can curb cravings and reduce overall calorie intake, positively contributing to weight loss efforts.

Here are the three whey protein products that are the best for weight loss:

1. Whey protein concentrate: This is the most common form^[12] of whey protein. It contains low levels of fat and carbohydrates and is typically 70-80% protein by weight.
