Why You Should Buy a Weight Loss Protein Powder


Short Answer: To allow yourself every possible advantage for a healthy weight loss and redefining your physique naturally.

Studies have shown that protein supplements are the best and most convenient choice in supporting high-quality weight loss as compared to other weight loss supplements that may have negative side effects. A quality protein powder will help supplement the daily amount of protein required by your body and also help you to reap the benefits from every exercise session.

If your goal with physical exercise or resistance training has always been to get shredded, lose as much fat as possible and gain muscle, a weight loss whey protein powder definitely gives you an edge over a standard whey protein. 

A protein supplement with weight loss benefits can also help with your cutting calories or when you’re eating fewer calories than you’re burning to lose weight, get muscular and ripped, or are aiming for both.

With the addition of weight loss ingredients to the formula, the power of a regular whey protein supplement gets enhanced in a way that can benefit your weight loss and muscle-building goals. However, this is only possible if you consistently maintain a low-calorie diet on a daily basis (more on this below).

If you have already been using whey protein supplements regularly, or are currently researching the best quality whey protein supplements for yourself that not only helps you build muscle but also helps you look your leanest ever, you’ll be better off buying a weight loss protein powder to see those significant results you’re after, much faster.

How to use a weight loss protein powder effectively to see results?

The first and foremost criteria for any meaningful weight loss to happen is to eat fewer calories than you burn every day. In other words, a calorie deficit is a primary driver for weight loss.

If you have ever tried to lose weight in the past and failed, it was obviously because you were unable to maintain a daily reduction in consuming calories from all the foods you ate throughout the day.

Now, for a weight loss protein powder to work, you simply have to ensure you’re doing two things:

  1. Frequent Physical Activity (Exercise)
  2. Eating in a daily calorie deficit (Diet). This is the primary driver of weight loss. Ideally combined with an optimal protein intake if you also want to build muscle.

If you can follow through with these two recommendations and make it habitual to the point that it becomes instinctive, you will never have to worry about your health and nutrition. The weight loss protein powder will help meet your daily protein needs while also supporting your efforts in losing weight.

The first part of the recommendation is pretty much straightforward. You can choose to perform any kind of physical exercise that you enjoy doing and are passionate about. Both endurance and resistance-type exercise help preserve muscle mass during weight loss, and resistance-type exercise also improves muscle strength.

Secondly, the best way to ensure you’re eating in a daily calorie deficit is to track your calories and maintain a healthy calorie restriction of about 20 to 25% from your maintenance calories. 

That’s it! After all, the weight loss part is not at all complicated. The only difficult part is for you to discipline yourself to follow through every day.

What to Look for When Buying a Weight Loss Protein Powder (Buyer’s Guide)


To help you decide about the best weight loss protein powder for your needs and preferences, I will list a few important points worth considering before you choose to invest your hard-earned money in a weight loss protein supplement. 

1. Protein Per Serving

Since a weight loss protein is primarily a whey protein in powdered form, the quantity of protein you get in each serving is the first thing to look for. 

This particular factor is vital to achieving weight loss while eating a low-calorie diet as a high protein intake will help preserve your lean body and existing muscle mass.

You can know this by looking at the ‘Supplement Facts’ label on the protein powder. A serving size (in grams) close to the amount of protein per serving (also in grams) is a great choice. 

Although, in all weight loss protein powders, you will notice the addition of weight loss ingredients that will further increase the difference between the serving size and the protein amount you’re getting per scoop. This is completely normal and there’s nothing to stress about unless the difference is too large. 

The reason is that the formulas for all weight loss protein powders are developed keeping in mind the dual benefits offered to people who want to lose weight and build muscle at the same time.

Research also proves that only diets with a higher protein intake have been shown to have a beneficial effect in situations where people have regained weight after a successful weight loss. 

2. Ingredients

a. Protein Blend:

First, a high-quality protein supplement can either be made using plant-based proteins or animal proteins. Whenever deciding to buy a protein supplement, always look at the ingredients list that can be found at the bottom of the Supplement Facts label. 

For weight loss, both plant and animal protein work just fine. The only downside with plant proteins is they are lower in essential amino acids (especially leucine) as compared to animal proteins like whey.

Choosing between the two protein types is a personal choice that will differ for everyone. The best guideline while selecting your preference would come down to the protein blend. 

A higher-quality protein blend for a plant protein powder is a balanced combination of different plant-based proteins used in the formula like pea, brown rice, wheat, oats, soy, and potato protein.

On the other hand, a higher quality protein blend for an animal protein will have whey protein isolate used and shown as a primary ingredient. Whey isolate is a form of protein that is lactose and fat-free and is at least 90 percent protein by weight in comparison with whey concentrate (25 to 80 percent).

b. Weight Loss Ingredients:

Having a weight-loss ingredient blend in addition to a high-quality protein blend in a protein powder is what makes it worth buying. 

The truth is that most of your weight and fat loss results will happen through a lifestyle modification (diet and exercise) and a high-protein diet. 

The overall impact of the addition of weight loss ingredients to a protein powder will be very small. This is because there is limited scientific evidence about the effectiveness of natural substances in creating weight loss. 

But personally, I believe that these natural weight loss ingredients do work (as proven by a few studies) and support one’s weight loss efforts if one is already doing everything right with their diet and exercise.

3. Added Benefits

The two factors discussed above should be the major points that should dominate your decision in choosing the right weight loss protein powder for your needs.

To attract more people to their offering and gain an edge over the competition, many supplement brands market and offer added benefits to their weight loss protein powders. These benefits are mostly in the form of more ingredients added to the formula to make it appear more “healthy”. 

Greens, fruits, vegetables, digestive enzymes and probiotics, fiber, vitamins, and minerals… the list goes on. 

For a second, looking at all this will give you a feeling that you can get all the nutrients from the product to stay healthy without having to eat any real foods. This isn’t true! No supplement can truly ever replace real foods. Sure, we now have meal replacement products that work great and are convenient for people on the move looking to have a quick, healthy meal in a matter of seconds. But like all good things they should be consumed responsibly with a preference for eating real foods whenever possible.

These additional benefits are a plus point and a bonus factor which some people may want to consider in their buying decision. 

4. Additives and Other Junk 

An often-overlooked factor when buying a protein supplement is looking out for cheap fillers in the ingredient list as these supplement additives can sometimes cause food allergies for some people. In simple words, a filler is anything added to the protein that does not naturally occur in the whey production process. 

While all fillers are not harmful and are mostly added to enhance the taste, mixability, and digestion of the protein supplement, there are a few ingredients to avoid when choosing a high-quality whey protein supplement are following:

  • Artificial Sweeteners: Sucralose, Aspartame, Neotame, Saccharin, and Acesulfame Potassium
  • Fillers: coconut flour, psyllium, lecithin and sugars like sorbitol and maltitol
  • Gluten
  • Dextrins and Maltodextrin
  • Milk powders and milk solids
  • Vegetable oils, thickeners, and gums

And the majority forget to take this aspect into consideration before a buying decision. The reason is that no sports brand will ever advertise the inclusion of unhealthy fillers in the marketing of their supplements. 

As an informed buyer, it’s your duty to look out for any additives that you know you’re allergic to by looking at the ingredients list under the ‘supplement facts’ for a protein powder.

And if you’re already been taking whey protein supplements for a long time and your body’s indifferent towards these minor fillers added to the formula, then you can confidently skip this part for your buying decision.

5. Bottle Half Full?

This is one factor that definitely needs clarification as most people think that they have been ripped off by the brand when they receive their protein powder filled halfway. As a smart supplement buyer, it’s super important you know why this happens to keep realistic expectations with all protein powders.

Why is the bottle half full?

All protein powders are filled by weight, not volume. And all bottles are half-full as a consequence of the manufacturing process. The reason is that when the powder is being manufactured, there is a lot of trapped air within it, so during bottling, you have to have a larger bottle than you would otherwise. After the bottle is filled, the product will settle in the bottle, and all of the contents will fall to the bottom.

Rest assured, you will get the number of servings and weight promised, but it will just seem like the bottle is bigger than it needs to be.

Which is the Best Weight Loss Protein Powder?


We’re finally here! Our number one choice for the best weight loss protein powder goes to Muscletech Nitro-Tech Ripped. Why?

  1. Highest whey protein isolate protein per serving at 30 grams
  2. Weight loss ingredient blend of L-carnitine L-tartrate, CLA and Decaffeinated C. Canephora Robusta (Ripped+Matrix) of 950 mg.
  3. Weight loss results are backed by a 60-day study using the key weight loss ingredient C. Canephora Robusta following a low-calorie diet and moderate exercise.

Be reminiscent of the fact that a weight loss protein powder will only give real results when used in conjunction with an exercise program along with a calorie deficit diet.
