Whey protein is a collection of proteins found in whey, a byproduct of cheese-making. When a coagulant (usually renin) is added to milk, the curds (casein) and whey separate; whey protein is the water-soluble part of milk. As a supplement, it’s sold as dry powders with various levels of processing that affect how concentrated a source of protein they are and how fast they’re absorbed.
What are the benefits of whey protein:
It’s a high quality, well-absorbed source of protein that’s very useful for hitting targeted daily protein goals. Its benefits extend to the benefits of increased protein intake in general, such as augmenting muscle gain in conjunction with resistance training, limiting muscle loss during low-calorie diets, and modestly limiting fat gain during periods of excessive calorie intake. These effects aren’t exclusive to whey protein but it will likely be more effective than most other protein sources per gram.
Whey does not harm the liver or kidneys, but it can exacerbate pre-existing damage. People with damaged livers or kidneys should exercise caution when increasing protein intake quickly without the guidance of a doctor.
How to take:
Recommended dosage, active amounts, other details
The amount of whey protein to supplement depends on individual daily protein goals. For example:
If you are an athlete or highly active person attempting to lose body fat while preserving lean muscle mass, a daily intake of 1.5-2.2g/kg bodyweight (0.68-1g/lb bodyweight) is a good goal.
If you are an athlete or highly active person, or you are attempting to lose body fat while preserving lean mass, then a daily intake of 1.0-1.5g/kg bodyweight (0.45-0.68g/lb bodyweight) is a good goal.
If you are sedentary and not looking to change body composition, a daily target of 0.8g/kg bodyweight (0.36g/lb bodyweight) is a good goal.
If daily protein targets are achieved through dietary protein alone, supplementation is unnecessary. Obese individuals should not follow the above recommendations, as bodyweight calculations would result in very high dosages. Obese people should calculate their protein targets based off of what their weight would be, assuming an overweight BMI.
