Bodyscience Whey Protein Iolate

• High protein.
• Low fat.
• Low carbohydrate.
• Superior taste and texture.

• Ion exchange filtration
• Micro-filtration.
• 
  

To maximise lean muscle mass it is advised that small meals are consumed regularly across the day (Houston, et al., 1999 ). Body Science Whey Protein Isolate (WPI) is a high-protein, low-fat and low-carbohydrate protein powder. Our WPI is a unique protein blend of two key processing methods, ion-exchange filtration and micro-filtration. Our blend of WPI results in a superior taste, texture and functional properties.

Protein Q&A

Q1. Is protein supplementation necessary?
Ultimately weather protein supplements are of value will depend on the consumer's specific needs and habitual dietary intake. Many health professionals imply that protein supplementation is unnecessary and that the recommended daily intake for protein is easily achieved via normal dietary intake. However, this argument is based on the assumption that everyone consumes a well balanced diet containing a range of high quality protein sources. In today's hectic world how many people actually achieve this? If you don't achieve your recommended daily intake of protein each and every day a protein supplement would defiantly be of benefit.

Additionally this argument fails to take into account the differing needs of individuals within our society. What about athletes and/or bodybuilders who want to maximise their lean muscle mass. If you eat three meals per day your protein intake is limited to three intakes per 24 hours. Protein synthesis is a continuous activity that requires a balanced supply of amino acids (Houston, 1999). By consuming protein supplements you can increase the frequency of protein ingestion, which will assist in maintaining blood amino acid concentrations across the day. This may increase protein synthesis (Houston, 1999), which could be of benefit to those wanting to maximise their lean muscle mass.

In recent years there have been a number of research studies that have indicated that
ingesting protein and carbohydrate prior to and after training can produce a greater increase in protein synthesis (Tipton et al., 2001;Rasmussen et al., 2000). Over weeks or months this may lead to greater protein accumulation therefore resulting in greater gains in muscle size, strength and athletic performance. Obviously the form of protein ingested prior to training is immensely important so as to not induce gastrointestinal distress that could ultimately impair the quality of your training. Protein supplements can provide a quality source of protein that is rapidly absorbed without causing the gastrointestinal distress that can be associated with whole food protein sources. Consequently, protein supplements may be a more practical protein source for athletes wanting to consume protein in close proximity to exercise.

Finally, what about those individuals that want to maintain their dietary protein intake while reducing their calories. Protein supplements allow protein to be consumed without the saturated fat, carbohydrate and unnecessary calories that come hand in hand with many whole food protein sources. This can ultimately allow the individual to meet their protein requirements while maintaining a low calorie intake.

Therefore the debate as to weather protein supplementation is or isn't necessary is not as black and white as some health professionals would imply. It depends on a number of factors including a person's normal habitual protein intake, their lifestyle and their natural taste preferences. The best judge of whether protein supplementation is necessary is the consumer.

Q2. How much protein do I need per day?
Recommended protein intake for adult individuals who are inactive or sedentary is 0.75g/kg/day (National Health and Medical Research Council, 2004). This means that if you are a 70kg office worker that does no exercise your daily protein intake would be 0.75g x 70kg = 52.5g per day. However it is generally accepted that those involved in exercise or training have higher protein requirements. Those involved in strength (weight) training are generally advised to consume around 1.6-1.7g/kg/day, while those involved in endurance training (eg triathlon) are generally advised to consume around 1.2-1.4g/kg/day (Lemon, 1998). Therefore if you were a 100kg bodybuilder you would be advised to consume around 1.7g x 100kg = 170g protein per day. Likewise if you were a 65kg Triathlete you would be advised to consume 1.4g x 65kg = 91g protein per day.

Q3. What is Whey protein?
Whey protein is derived from the process by which cheese is made from milk. In reality it is actually a by-product of the cheese making process. Via a number of purifying processes the final product sold as whey protein contains upward of 80% protein.

Q4. What is the difference between whey concentrate and isolate?
Whey protein isolate is often seen written as WPI, while whey protein concentrate is written as WPC. Although they are both considered whey protein, they vary in their composition and the manufacturing processes involved in their production. WPI has a slightly greater protein content of about 90%, while WPC is approximately 80% (Kreider, 2002). Both are excellent protein sources.

Q5. How can protein supplements be used during weight loss?
One of the advantages of ingesting adequate protein and performing resistance training during calorie restriction is that it helps maintain your lean muscle mass (Demling et al., 2000). This is important as lean muscle tissue burns calories and helps ensure your metabolic rate remains high. Lets remember that it is fat (not weight) that you want to lose. If you lose muscle mass during energy restriction your metabolic rate will drop and it will make it increasingly difficult to lose the desired body fat. However, maintaining an adequate protein intake while simultaneously restricting your calorie intake can be difficult as many protein sources are also high in fat and calories. Protein supplements are a source of protein that contains very little fat. If you take Body Science WPI as an example, one 30-gram serve provides 27grams of protein. To achieve this protein intake (27 grams) from a whole food source such as eggs you would need around four eggs. However as seen in figure 1 (below) WPI provides a method of ingesting protein while minimising fat intake.
