Whey concentrate

When whey is collected as a by-product of cheese making process, it undergoes several processing steps to increase its protein content.

After a sufficient protein concentration is achieved, the protein is then dried down to form whey concentrate containing 80% protein by weight, rest is carbs and fats

Whey isolate

When a concentrate whey protein undergoes further processing to reduce the content of fat and carbs, a whey protein isolate is produced with 90% protein by weight

Difference between whey concentrate and whey isolate

  1. Protein content – a (wpc) consists of 80% protein by weight whereas a (wpi) contains approx 90% protein content by weight.
  2. Which is better- see this varies with person to person. If a my goal is to gain muscles while looking at the budget, i will go for a whey protein concentrate (wpc). If i am looking to complete my daily protein intake while losing weight, i will go for a whey protein isolate (wpi) as it has less calories in comparison to wpc.
  3. Lactose- this is necessary to understand that there are many people who are lactose intolerant and cannot have milk or dairy products, they can go for whey protein isolate (wpi) as its lactose content is up to 1gram.
  4. Cost- a whey protein isolate is relatively very costly as compared to a whey protein concentrate which creates a major difference between both types of whey protein

Whey protein concentrate OR whey protein isolate for weight loss.

As we clearly know that calories in vs calories out is the only weight to gain or lose weight, its nearly impossible to believe that whey protein concentrate, or whey protein isolate can cause weight loss.

Yes, they do assist in weight loss by replacing 120 calories whey protein isolate scoop with a 300calorie meal with same thermic effect.

If we have to choose any of both wpc or wpi for weight loss, whey protein isolate(wpi) is the answer as it has relatively less calories as compared to a whey protein concentrate(wpc)

So, now this is wrong to say that whey concentrate is better than whey isolate. It’s just that both are different from each other.
