Protein Shakes For Weight Loss: How They Can Support Your Goals!

It can be tempting to buy protein shakes and think they can be an elixir to your weight loss journey. The one fix that you have been longing for yet they still need to be used correctly.

When they work, protein shakes can be genuinely convenient and make you feel like you can smash your fitness goals.

However, protein shakes alone will not act as the one solution for lasting weight loss.

In this guide, we will look at protein shakes for weight loss: and how they can support your goals.

How Protein Shakes Can Support Your Weight Loss Goals

Protein shakes aim to provide your body with all it needs so you can effectively replace a meal. The protein fills you up and controls your hunger hormone levels by suppressing your appetite. 

Instead of eating one or two meals each day, you drink a shake and your body still gets what it needs.

You will still eat one or two meals every day but these will likely be relatively small and feature few calories.

Some extreme methods involve only drinking protein shakes for a few consecutive days. While this may work in theory, it is not a recommended practice by health professionals.

Perhaps the key to using protein shakes effectively is to use them in moderation. If you can successfully replace your meals with one and not feel hungry then keep going.

Only after a few weeks, or even months, of this program should you try to replace more than one meal daily with a protein shake.

Try having a single protein shake to replace one meal and see how it goes. To make the protein shakes even more effective, fit in some more healthy and sustainable lifestyle choices.

Weight-loss plans prove to be the most effective when they bring together various factors. Alongside a protein shake should be healthy meals, a fitness plan, and perhaps going without alcohol.

The Science Behind Protein Shakes For Weight Loss

Maintaining and losing weight can have a lot to do with getting sufficient amounts of protein. That’s where protein shakes come in as they are preferable to refined carbohydrates.

Protein is a remarkably dense substance so it can take a while to be digested. That should keep you comparably fuller for longer than if you ate different foods. 

Consuming protein can also go some way to stabilizing your blood sugar levels. Between meals, your blood sugar levels can drop.

You may feel hungry or hangry and be tempted to graze with some snacks. The protein will look out for your blood sugar levels and help regulate a hunger hormone known as ghrelin. 

Certain types of protein, specifically whey, can also help you build lean muscle at the expense of fat. If you prefer resistance training then incorporating whey-based protein shakes is ideal.

As you build muscle, you should also find yourself burning more calories as you rest. With the addition of protein, this practice is enhanced as your metabolism improves.

This is known as food’s thermic effect, the ability to burn calories by digestion alone. 

As protein is denser than carbohydrates, it is slower to digest so needs more energy to break it down.

With more protein in your diet, you should increase your calorie burn and boost your metabolism. 

Finding The Right Protein Shake

Protein shakes can come in a range of flavors, types, and formulas. That means you should try to find one that works for your palate and body type.

Also, aim for a protein shake that is convenient for your lifestyle. Perhaps a ready-to-drink pre-mixed shake or one you can create yourself from protein powder

The Different Types Of Protein

Another factor to consider in finding the right protein shake is to look at the different types of protein.

Yes, there are several to consider and there may be one which is just right for you. These different types of protein include casein, whey, soy, egg, pea, rice, hemp, and cricket.


Casein is a great option for weight-loss goals as it can make you feel full for longer. That’s due to how slowly it is digested by the body. Derived from cow’s milk, it can help you build muscle too. 


As a relatively inexpensive protein, whey is an exceedingly common component of protein shakes.

Like casein, the protein is formed from cow’s milk and is easily absorbed by the body. If you are looking to build muscle then whey is probably the way to go.


Should you want to embark on a plant-based diet then soy is one of the best ingredients to include. Soy contains all those essential and relevant amino acids.

Your body will be pleased with the choice so it can create new proteins. However, soy does contain phytoestrogens which may harm your hormones. 


Your body will easily absorb egg as a natural protein so consider having it in a protein shake. What you may not realize is that all the nutrition is from egg white as no yolks are included.


Vegetarians and vegans can look to the humble pea as a source of protein. Another complete protein yet this one is low in the amino acid known as methionine.

Fix that by adding nut milk or nut butter as ingredients to your shake.


You may have been recommended a portion of brown rice in your diet if you are looking to lose weight.

Not only is it filling but it works as a complete protein that is low in the amino acid, lysine. As a protein powder, brown rice is also a great choice for vegans.  


As a plant-based protein, hemp is also low in lysine. You may want to add some almond butter or tofu to your protein shake to make up for it.

Look at hemp as a complete protein source that comes with a healthy serving of omega-3 fats.


That’s right, protein is sourced from actual bugs. Using crickets as a protein source could also help solve hunger issues across the globe.

Final Thoughts

While protein shakes may not be the one fix to your weight loss goals, they can help. Use the shakes with other tools such as resistance training and nutritious meals.

Find the right protein shake for you and use it as a sustainable way to lose weight. Protein can suppress your appetite, boost your metabolism, and increase your muscle mass.
