What I Think of the Protein World Slender Blend [Review]

February 26, 2017

A couple of weeks ago, Protein World teamed up with Kim Kardashian! I was excited to hear about the partnership as it’s Khloe’s first major fitness collaboration and was even more motivated to try out Protein World’s products (which I’d been curious about for a while now)–and specifically the Protein World Slender Blend line. As fate would have it, Protein World reached out to me and asked if I wanted to try out the Protein World Slender Blend line. Um, YES, and thanks for reading my mind!

As such, I wanted to share with you all my thoughts on the products in my Protein World Slender Blend review. Read on to find out whether or not they matched my expectations.

What’s in the Protein World Slender Blend Line?


There are two Protein World Slender Blend plans; one which includes their vanilla porridge and the other which includes their chocolate porridge. I received the Protein Slender Blend with chocolate porridge. Their plans also contain:

  • the Slender Blend (weight-loss) protein powder
  • hunger buster capsules
  • fat metaboliser capsules
  • a Protein World shaker
  • 30-day challenge containing recipes and workouts

The Slender Blend line is designed as a whole to help kickstart your weight-loss journey. However, as you may or may not know, I’m not necessarily looking to lose weight, but rather to build lean muscle and to slowly decrease my bodyfat.

Khloe Kardashian’s partnership with Protein World emphasizes the fact that they want to help others become the best version of themselves, and that’s the mindset I had using these products.

How I Use THe Slender Blend

Slender Blend Weight Loss Protein Powder

As I said, I’ve been using the Slender Blend products as a way to supplement my current fitness goals. I use the Slender Blend protein powders to quickly whip up protein shakes after my workout or in the late afternoon, as a way to curb my cravings.


The Protein World weight-loss protein powder is probably one of the best tasting protein powders I have tried so far–it’s sweet, but not overly so, and has a delicate vanilla and banana flavor. I literally just mix it with water and then I’m good to go. Furthermore, at only 141 calories per serving and 24 grams of protein, it’s an easy way to increase your protein intake. And the protein powder also contains Protein World’s Vitamin & Mineral Blend which is a fun, little bonus (although, I have to say that multivitamins are absolutely not needed if you’re eating a healthy, varied diet).

Fat Metaboliser Capsules

I use the fat metaboliser capsules as directed. One pill after breakfast, and another after lunch for the first week, and then upping the amount to two pills during the second week. I decided to stop taking them after two weeks because I didn’t want to become too reliant on them. I actually did see a small difference in ab definition when I was taking them which was quite exciting! And I didn’t need to drink coffee at all while taking them because of their high caffeine content.

Hunger Buster Capsules

I haven’t used the hunger buster capsules because I honestly don’t have too many issues in dealing with hunger. I personally also think that if you’re hungry then you should probably eat! But I do understand that others may appreciate this product especially if they work long shifts with little to no access to food.

Slender Blend Porridge (Chocolate)

I normally alternate between two types of breakfast’s; chicken sausage with avocado Sourdough toast and 1-2 eggs or oatmeal with protein powder. On weekends, I sometimes do make protein pancakes (get my recipe here). For the past few weeks, instead of eating my usual oatmeal breakfast, I will make some slender blend porridge using vanilla cashew milk and top it with some fruit, such as raspberries or blueberries. 


The porridge is SO freaking delicious!!! And it contains chia seeds and flaxseeds to help you get in your healthy fats and boost your fiber intake (don’t doubt the health benefits of fiber, my friends). The only thing I find is that the porridge mix doesnt microwave well–it’s either too watery or turns into this weird, cake-like texture. I’ve solved this by just having it ‘overnight-oats’ style. Click here to see how I make it.

30-Day Challenge

I still have yet to try out one of the workouts, or delicious recipes, in this booklet but will update this review once I do. The workouts look a little basic and great for beginners.

Honestly Fitness approved

All in all, I am very impressed with Protein World’s Slender Blend line! While I unfortunately can’t truly comment on it’s ability to help with weight-loss, I can tell you that I noticed a small difference in my body even despite being quite indulgent with my diet these past few weeks (bulking life haha).


I thought the porridge and protein powder were delicious and made getting more protein into my diet easy and convenient. While I would never encourage you to buy supplements if you couldn’t afford it, if you can afford it, then I would definitely steer you towards trying out Protein World products.

      Hi Sabikah!
      You might feel a little jittery because they contain a lot of caffeine–so don’t take the pills and drink coffee!!! So be aware of that and follow the recommended dosage. Other than that, I didn’t have any other side effects.
      Hope that helps xx
