Weight loss is a difficult goal to achieve and it doesn’t matter if you are new to the “protein scene”. Choosing which protein shake to use can cause confusion, especially when you have to cut calories to lose some weight.
In this article, we have decided to analyze the characteristics of the whey protein also known as whey. We want to find out, using nothing less than science, what are the best whey proteins for weight loss?

Whey Protein Concentrate:
Whey Protein are all whey based products. What makes whey protein concentrate different is the way it is refined. Instead of being heated, the whey concentrate is microfiltered. This treatment allows it to maintain its pure amino acid concentration while remaining good. Whey concentrate is probably the most popular type of protein on the market today.
Whey Protein Isolate:
Whey Protein Isolate contains around 90% protein, making it an incredibly lean powder. It is low in carbohydrates, calories and fat. The high protein content is one of the main reasons why it is so popular with people who want to lose weight. Whey Isolate is subject to a process called ‘cross-flow microfiltration’. This process separates proteins from fats, cholesterol, lactose and carbohydrates, creating ultra-pure proteins.

Whey Protein reduces hunger and appetite
Whey protein is well known for helping you feel full longer (Westerterp et al. 2004). A study conducted in 2010 analyzed food consumption after drinking a whey protein shake. Half of the subjects were given a placebo (zero calories and zero protein), while the other half was given a smoothie made up of 13%, 25% or 50% protein.
Subjects were given a pasta lunch 90 minutes after consuming their shakes, with results showing that those who took the protein shake ate much less. This effect was seen more in men than women who ate 450 fewer calories on average, compared to those who took the placebo shake (Astbury et al. 2010).
Studies have also found that when consuming a protein shake it increases appetite by reducing hormones such as GLP-1, but also lowers the levels of the hunger hormone ‘ghrelin’, (Lejeune et al. 2006), which is one of the reasoning for this result.
