What Are The Three Types Of Whey Protein

How to Use Whey Protein for Weight Loss

When you browse online or at your local nutrition shop for whey protein products, youll probably notice different forms of whey. The main difference in the types of whey protein is how theyre processed. When you understand how theyre made, you can better choose the right type for your health and fitness goals. Here are the three most common forms of whey protein.


Whey protein concentrate is the least processed form of whey, so it contains the highest levels of lactose , fat, carbohydrates and nutrients. Food manufacturers use WPC to replace fresh dairy and eggs in products like sauces, soups and baked goods because it adds flavor, color and texture and extends shelf-life. However, it has the lowest protein content out of the threetypically 70-80%.


Whey protein isolate is made when whey is filtered and processed. It contains the most protein, 90% or more, and less lactose. For this reason, sports nutrition companies often prefer WPI for use in supplements, bars and other protein products because of the higher protein content. However, it lacks some of the beneficial nutrients found in the concentrated form.


Whey Satiates Your Appetite

Of all the macronutrients , protein is best at making you feel satiated, or full. If you’re cutting calories, choosing foods that are as satiating as possible will help make sticking to your diet less stressful.

Studies show that milk proteins such as whey may satiate your appetite better than some other protein sources. But, having a high enough protein intake in general is the most important thing. Eat plenty of dietary protein from food sources like meat, eggs, and fish, and supplement with whey protein to max out your protein intake.

Protein is even more filling when paired with fiber. Make a meal replacement shake with whey protein powder, fruit, and some leafy greens to fill up on minimal calories.

“This is a great vegan blend that consists of pea, pumpkin seed, sunflower seeds, flax, and hemp,” says Lauren Antonucci, RDN, the owner of Nutrition Energy. She points out that it also has added greens for fiber, as well as probiotics for gut health, which solidifies its place on the list of best protein powders for weight loss.

How Protein Powder Can Help With Weight Loss

In order to prioritize both fat loss and muscle mass retention, a diet rich in protein is necessary, but it might be hard to get the required amount of protein you need from your diet alone. This is where a protein powder supplement can truly shine. Instead of forcing down another chicken breast or a can of tuna, you can opt for a delicious dessert-flavored protein shake.

Protein powder can also be a fantastic way to add protein to your diet without any excess calories from carbohydrates or fats. Another added benefit is that protein is the most satiating macronutrient, which means that it will help you feel full for a longer period of time, which can help you consume fewer calories throughout the day. These benefits, especially when used in conjunction with a well designed resistance training program, will have you well on your way to reaching your weight loss goals.

Casein Can Keep You Fuller For Longer

Natural Whey Protein For Weight Loss

Similar to whey protein, casein is milk-based and contains all the essential amino acids. However, it is absorbed slowly in the body .

Casein has also been linked to improved body composition and increased feelings of fullness.

Among male athletes, taking 70 grams of casein in the morning and evening over 8 weeks increased lean muscle mass by an average of 2.4 pounds .

Compared to whey protein, casein does not seem to be as effective at increasing muscle mass. However, it does appear more effective than other protein supplement sources, such as soy and wheat protein .

When it comes to satiety, whey protein is absorbed quickly and can enhance feelings of fullness. Casein is digested more slowly and may keep you fuller over a longer period of time .

One study followed overweight men on a weight loss diet that included either whey or casein supplements. After 12 weeks, those taking casein supplements lost an average of 8% of their body weight. Those taking whey lost an average of 4% .

However, this study was small and the evidence is mixed.

Other studies comparing the effects of casein and whey found no significant difference in weight loss or body composition in the long-term, making them equally as good for weight loss .


Casein is absorbed slowly, so may be more satiating in the long-term. Taking it regularly has been linked to weight loss and improved body composition.

The Importance Of Protein

Protein is considered one of the bodys most essential nutrients because its valuable to every cell in the body. Its required for maintaining our bones, muscles, organs, skin, and nails and even helps keep the systems of the body running properly.

Still, protein is most well-known for being a key component in sustained weight loss. This is because research has shown that consuming diets higher in protein is not only safe for otherwise healthy individuals, but these diets may provide a host of health benefits, including helping boost metabolic rate and energy expenditure, increase satiety, and reduce caloric intake, as well as preserve and build calorie-burning lean muscle.

Whey Protein Blocks Fat Storage

An intriguing new line of research suggests that Whey promotes body fat loss by blocking fat storage. In a recent French study, laboratory animals were fed a normal diet, a high-protein diet, or a Whey-enriched high-protein diet for 42 days. At the end of the study period, the animals fed the Whey diet weighed 30 percent less than those fed the normal diet and 17 percent less than those fed the regular high-protein diet, yet the Whey-fed animals had the highest levels of lean body mass of the three groups. The researchers conducting the study attributed these results to reduced fat storage caused by the high concentrations of branched-chain amino acids in the Whey product used.

Scientists are still trying to figure out how dairy foods boost fat loss in dieters, but they believe calcium plays a pivotal role. Calcium is a crucial player in fat metabolism and appears to both reduce fat storage and increase fat burning when consumed at adequate levels during periods of calorie restriction. But calcium is clearly not the whole story, because studies pitting dairy foods and calcium supplements head-to-head have found that dairy foods are far more effective. At least half of the fat storage-reducing effect of dairy foods is attributable to two specific components of Whey: branched chain amino acids and a protein fraction known as ACE inhibiting peptide.

Muscle Building And Weight Loss


Whey protein supplementation along with resistance exercise can help improve muscle protein synthesis and promote the growth of lean tissue mass.

A study published in the International Journal of Sport Nutrition and Exercise Metabolism concluded that whey protein supplementation during resistance training offers some benefit compared to resistance training alone. In addition, males who supplemented with whey protein had a greater relative gain in lean tissue mass.

Much better gains in strength are associated with whey isolate supplementation compared with casein.

This was demonstrated in another study published in the International Journal of Sport Nutrition and Exercise Metabolism, which concluded that in two groups of matched, resistance-trained males whey isolate provided significantly greater gains in strength, lean body mass, and a decrease in fat mass compared with supplementation with casein during an intense 10-week resistance-training program.

If you want to buy whey isolate supplementation, then there is an excellent selection online with thousands of customer reviews.

Who Needs To Add Whey Protein To Their Diet

Whey protein is just one of the many options available for getting enough protein in your diet. As one of the three necessary macronutrients, protein plays an important role in muscle creation, as well as blood, enzyme, and antibody health.

The recommended daily allowance for protein is .8 grams for every kilogram of body weight. You can figure out your own RDA by first multiplying your weight by .454. Next, multiply that number by .8 this will be the number of protein grams you need according to your body mass. For example, if you weigh 150 pounds, you need around 54 g of protein per day. Your doctor can help you figure out your ideal intake based on your age, health status, and activity level.

Most people in the United States get enough protein in their diet, but if you have an underlying condition that makes hitting that target difficult, consult your doctor to see if you might benefit from supplementing your diet with whey protein.

/5things To Keep In Mind While Buying Protein Powder


While the market aisle is full of different protein powders, not all of them are good for health. When shopping for protein powder there are a few things you need to check the label for as these ingredients can sabotage your weight loss process.

Artificial sweeteners: Artificial sweetener is as harmful to health as normal sugar. Look for sucralose, splenda or aspartamine in the protein powder. These ingredients may lead to indigestion, headache, migraines, gastric distress and worst of all weight gain.

Artificial flavouring: Artificial flavouring may make the protein powder taste better but impact your health. Most protein powder processing companies do not specify what they have added to their product for flavouring purposes. It is better to avoid flavoured protein powder.

Carrageenan: Carrageenan is derived from seaweed and is believed to cause digestive problems and intestinal inflammation. It is also linked to cancer.

Vegetable Oils: Some protein powders also contain vegetable oils as a thickening agent. But these sources of fat are not considered good when trying to shed kilos.
