Whey Protein Types For Weight Loss

Whey Protein Concentrate:

All whey products are produced from milk, however, what makes whey protein concentrate different is how it’s refined. Rather than being heated, whey concentrate is micro-filtered, allowing it to keep its pure concentration of amino acids while remaining smooth and silky to the taste. Whey Concentrate is probably the most popular types of protein on the market today.

Whey Protein Isolate:

Whey Protein Isolate contains around 90% protein contents, making it an incredibly lean powder. Low in carbohydrates, calories and fats, while being high in protein is one of the main reasons for it being so popular in the weight loss community. Whey Isolate is subject to a process called ‘cross-flow micro-filtration’, separating the protein from fat, cholesterol, lactose and carbohydrates, making an ultra-pure protein shake.

Whey Protein has much more benefits than just weight loss, if interested here’s an article to keep you entertained “Health Benefits of Whey Protein

Whey Protein Decreases Hunger & Appetite

Whey protein is well known for helping you feel fuller for longer (Westerterp et al. 2004). A study performed in 2010 analysed food consumption after drinking a whey protein shake. Half of the subjects were given a placebo (zero calories and zero protein), whereas the other half were given a shake made up of either 13%, 25% or 50% of protein. Subjects were given a pasta-based lunch 90 minutes after consuming their shakes, with results showing those who had taken the protein shake ate much less. This effect was seen greater in men than women who on average ate 450 calories less, than those who took the placebo shake (Astbury et al. 2010).

Studies have also compiled that when consuming a protein shake that it increases appetite reducing hormones such as GLP-1, but also reduces levels of the hunger hormone ‘ghrelin’ too, (Lejeune et al. 2006), which is one of the reasonings for this finding.

In another study, Leidy et al (2011), looked at finding the effects of consuming high protein diets on appetite and satiety in overweight and obese men. Here the participants were told to increase their protein intake to 25% of total calories, this helped to cut cravings down on average by 60% and late night snacks by 50 % too.

It’s important to note here that if consuming a shake to lose weight that you double check the contents. As if choosing the wrong protein shake, could, in fact, see you going into a calorie surplus rather than a deficit, the complete opposite to what you want.

Whey Protein May Increase Metabolism

Adding whey protein shakes into your diet is an easy, cost-effective way of boosting your protein intake for the day. When it comes down to weight loss there are a few phrases you may have heard, one being metabolism.

For those unaware, metabolism is basically the process in which your body converts what you eat and drink into energy. The quicker the metabolism you have the more calories you burn, and it stops your body from storing the energy as fat (Ashtary et al. 2017).

Studies have concluded that having a high protein intake through the day boosts metabolism and helps to burn more calories than usual (Veldhorst et al. 2009). One of the reasons as to why protein can help boost your metabolism is the proteins ability to promote lean muscle mass development, especially during resistance training.

Having more muscle mass requires more maintenance, for example, studies have shown that 10 pounds of muscle mass would burn around 50 calories in a day, whereas 10 pounds of fat would burn around 20 calories (fonseca et al. 2018).

One term that individuals don’t associate with whey protein consumption is its thermic effect. TEF to be short is your body using calorie to simply digest and break down the food that you eat.

Unfortunately, that doesn’t mean you lose weight while you eat (that would be a dream) but it just means that your body processes fewer calories due to them already being used so less can be stored.

The fewer calories your then allowing your body to consume helps to be in that special calorie deficit needed for weight loss. Although there are no specific figures on protein TEF effect, it is well documented that protein has a much higher thermal effect than other macronutrients such as carbohydrates and fats (Westerterp et al 2004).

Whey Protein Helps a Calorie Deficit

When trying to lose weight there is one basic principle, you must be in a calorie deficit. What this means is simply you must be using up more calories than what you consume. This allows your body to use its fat stores to create energy to survive and as such you start to lose weight. It might sound simple but some people forget about rule number 1.

You could be eating the healthiest of meals, performing intense exercise but if not in a calorie deficit, you won’t lose any weight at all. As we’ve talked about above consume a high protein diet can help reduce hunger hormones which in turn stops you from snacking, helping with your calorie deficit. Whey protein has also shown to reduce insulin and blood sugar levels and regulate them to a consistent level (Patel, 2015). If blood sugar levels drop it can cause your body to crave sugary or fatty foods.

Learning about how we actually lose weight should be your first protocol when it comes down to trying to get slim for summer – The Basics of Weight Loss article explains in detail about what you need to be doing to help aid your fitness journey.

How To Get Enough Protein In Your Diet

There’s no way of denying it that you can, of course, get all your protein and macronutrient needs from the food that we eat, however, if weight loss is your main goal, then hitting a certain number is near impossible without the help of some protein powders – “Why You Need More Protein While Dieting” can help explain this a little further. 

Low in fat, low in carbohydrates, low in sugar, low in calories, but high in protein is the reason why they’ve become so popular in the hunt for that dream physique. Not too mention the amount of time and money saved from consuming a shake rather than having to prep a full high protein dish. It’s a no brainer really.

However, making sure you choose the best protein shake to suit your diet should be at the top of your checklist. Lucky for you the guys at THE PROTEIN WORKS have done exactly that and selected some of their favourite weight loss protein shakes below.
