Diet Whey Isolate Fat Loss i-SHAKE™

Diet Whey Isolate Fat Loss i-SHAKE™ is our purest whey protein isolate in our innovative i-SHAKE™ shake form. Renowned for having the highest protein content and lowest carbohydrate and fat content of any protein in sports nutrition today, Whey Protein 97 has been in such high demand since its launch it only made sense to immediately launch the i-SHAKE™ version.

Worth noting is because of the purity and premium grade nature of our Whey Protein 97 no mesh or ball is necessary to mix it. As with all our samples just a few shakes and instant mixing is guaranteed.

Diet Whey Isolate i-SHAKE™ Concept

Regarding the concept of the i-SHAKE™, it originated from our collaboration with Everton Football Club to pioneer what has been dubbed by the media as a 'Premier League First'. When creating a range of bespoke recovery formulas for the first team, The Protein Works™ team were faced with the task of creating an easy to drink, transportable, durable delivery system. So the i-SHAKE™ shake was born and after listening to your feedback for samples to trial more of our innovative flavours we decided to create Whey Protein 97 i-SHAKE™.

Diet Whey Isolate i-SHAKE™ Nutritional Insight

For those not familiar with the impressive nutritional profile of Whey Protein 97, it’s renowned for having less than 1g of fat and less than 1g of carbohydrates per serving. Sourced from premium grade whey protein isolate, it has an amino acid profile that's been scientifically shown to aid fat loss meaning it is ideal to be used in conjunction with our other weight loss products.

Specifically looking at the fat loss properties of Whey Protein 97 have a lot to do with the unique manufacturing process it undergoes. The protein is extracted directly from skimmed milk using membrane technologies at low temperature through two processes known as microfiltration and ultrafiltration. This ultimately produces a very pure form of whey protein that's had its lactose, carbohydrates, calories and casein removed. This leaves ultra pure whey protein isolate, a protein that is capable of aiding fat loss.

Diet Whey Isolate i-SHAKE™ Ingredient Breakdown

It contains such a lean macro nutrient profile that not only helps prevent fat storage but also helps promote weight loss. Whey Protein 97 has been shown to lower your body fat percentage through 3 different dietary mechanisms:

  • Firstly, studies have found it has a 'thermic effect'. What this means is unlike other foods, Whey Protein 97 actually requires calories just to digest it because of its high protein content.
  • Secondly, Whey Protein 97 has been shown to keep you satiated for longer meaning it curbs your cravings and helps you stick to your diet.
  • Thirdly, Whey Protein 97 has been found to have a naturally higher leucine content than most other proteins, an amino acid that studies have shown can further help increase the amount of fat your body is able to burn.

Great for flavour samples
I can't say anything more than what everybody else has. They taste amazing, I have mixed with water and almond milk, no chunks, and easy to throw in your bag. Because they all taste so good I'm now stuck for a choice I want all of them!

Great for sampling all the yummy flavours :)
These are great for getting a taste of all the fab flavours without breaking the bank - so far I've tasted choc silk, mint choc brownie and cherry bakewell in diet whey 97, all are lovely but mint choc brownie really is heavenly!
Lovely smooth texture and natural tasting flavours, I highly recommend this stuff :)

Love these!
These i-shakes are absolutely perfect for long days when I'm on the move. I work on my feet all day and find these to be a handy little pick me up. Not only are these great for the purpose of convenience, but they're also super tasty. I have tried every flavour and have enjoyed them all. Banana and Caramel have to be my favourites though! Thanks TPW.

Q. When should I take Diet Whey Isolate 97?

A. It depends upon your lifestyle and goals, we recommend the following optimal serving times:
Immediately upon waking / 30 minutes pre workout / immediately after your workout / before you go to bed. Any other time during the day when you require additional protein intake.

Q. Is all whey protein isolate the same, regardless of which brand it is?

A. As with so many things in life, if you don't ask the right questions, you won't get the right answers! The quality of protein can vary significantly and therefore the protein content will do too. In addition, just because a product may be called Whey Protein Isolate it doesn't mean that it only contains whey protein isolate. We recommend you read the ingredients and nutritionals on the label to better understand exactly what you are buying. We can assure you that our Diet Whey Isolate 97 is purely whey protein isolate. At TPW™, we are committed to transparency and openness in all our products and that is why we provide the following information on all our protein products: 1. Product Profile - a complete overview of the product's background including our approval, location of manufacture and money back guarantee applicability. 2. Protein Insight - a complete breakdown of the types and quantities of protein contained in the product. 3. Product Testing - an up to date certificate of analysis which provides independent verification of the protein content

Q. How can I tell if the protein I use is good quality protein?

A. Key signs to look for are the level of protein declared on the label. Look for ultra pure whey protein isolate with a minimum of 97%. Unflavoured, ultra pure whey protein isolate should be smooth with a neutral dairy taste. It should be easy to mix and with little froth. Of course, the ultimate way to know is from the results you get from taking the product.

Q. Does your flavoured whey protein powder contain artificial flavouring and colouring?

A. Most protein supplements on the market today are made using artificial flavours and colours. We are committed to maintaining purity in all our products which is why we only use all natural flavouring and colouring with absolutely nothing to hide. Not only is this kinder to your body, but it also gives a more natural and real taste to your shake.

Q. What does "dry basis" and "as-is" mean when talking about protein content?

A. When you see a protein powder that states on the label the protein is given as "dry basis " this means that the moisture present in the powder is included in the total protein value. Moisture in dry protein powders are typically around 4%. However, when a protein supplement is stated "as-is" this means the actual protein content of the powder with the water content excluded. In other words, the true protein you will be consuming. As whey prices have increased significantly over recent years due to the large demand in the sports nutrition sector, some brands may not give you all the facts in regards to the true level of protein in their products. At TPW™, we believe in transparency to give you the utmost confidence when choosing your whey protein supplements. On all our protein products you will see both the as-is and dry-basis values declared. Once again, it's all about knowing what to look for.

Q. Is Diet Whey Isolate 97 suitable for vegetarians and vegans ?

A. Diet Whey Isolate 97 is suitable for vegetarians, but not for vegans.

Q. Can I take Diet Whey Isolate 97 with other supplements?

A. The simple answer is yes. We recommend you always check serving instructions on each product if you plan on taking a combination of supplements.

Q. What effects should I expect from taking Diet Whey Isolate 97 alongside my training regime?

A. Diet Whey Isolate 97 is the ideal supplement to for anyone looking to reduce their calorie intake while meeting their daily elevated protein requirements.

Q. Who should take / benefit from using Diet Whey Isolate 97?

A. It is ideal for anyone looking to diet and at the same time meet elevated protein requirements through intensive exercise and training. Of course, it is perfect for anyone who wants to avoid anything artificial in their diet.
