Slender Blend Quick Summary

Protein World Slender Blend is an okay protein powder that boasts thermogenic ingredients for fat burning.

However, there are only two fat-burning ingredients that heavily rely on caffeine to boost your metabolism. The quality of all the ingredients is not high enough to warrant the premium price tag.

Slender Blend Protein – What Does Slender Bend Do?

Slender Blend is a protein powder that claims to be a versatile health supplement. It states that it is a meal replacement shake, post-workout shake, and a low-calorie snack.

Some of the benefits of Slender Blend include:

  • Maintenance and development of lean muscle mass
  • Fat metabolism and weight loss
  • Healthy digestive gut
  • Overall health support

This sounds great but is Slender Blend protein the best choice for a weight loss supplement?

In this Slender Blend review, we’ll go in-depth on the ingredients, side effects, how to use Slender Blend, and if it’ll really help you achieve your fat loss goals.

Slender Blend Vegan

Slender Blend also comes in a Vegan formula.

The whey protein is replaced with a Protein World Vegan Protein Blend which is a mix of pea protein, quinoa protein, and hemp protein.

The sugar content in the Slender Blend Vegan protein is also very low compared to the original. This may explain some negative reviews about the vegan blend being untasty and inedible.

The Slender Blend Vegan protein is very similar to the original Slender Blend formula, however, it only comes in three flavors: Vanilla, Chocolate, and Salted Caramel.

How does Slender Blend Work?

Slender Blend Protein Powder claims to be versatile in that its formula will work as a post-workout shake, a light snack, and a meal replacement.

According to the label, here’s how Slender Blend works:

As a meal replacement, you substitute two daily meals of an energy restricted diet with meal replacements for weight loss.

As a snack or post workout, the whey protein contributes to the maintenance of muscle mass.

It also contains a “Protein World Thermogenic Blend” which is said to aid in fat metabolism to help you burn fat faster.

However, just because the product includes many ingredients to provide a variety of benefits, it does not mean that the product will be effective at providing all of them.

Slender Blend Protein Ingredients

Let’s take a look at some of the key ingredients in Slender Blend that contribute to its fat-burning abilities.

The main fat-burning ingredient in Slender Blend is its “Protein World Thermogenic Blend.”

The Protein World Thermogenic Blend contains two ingredients: Guarana Extract and Green Tea Extract.

Slender Blend Weight Loss

We’ll go more in-depth about what each of these fat-burning ingredients does and if it’ll actually work for you.

Guarana Extract

Guarana is a tree in which its seeds are grounded up into a powder and used in Amazonian medicine.

There is no research to support that Guarana itself is a fat-burning ingredient.

But it is known to be a high stimulant and contains compounds such as caffeine, catechins, and tannins.

Caffeine works by increasing your metabolic rate to speed up the body’s fat-burning process.

However, caffeine can cause potential side effects depending on your tolerance. It is also not recommended to have in the evening as it may cause sleeplessness.

Green Tea Extract

Green tea contains compounds called catechins which can aid in fat burning.

How this works is that the green tea catechins help the body release and break down fat and oxidize it into the bloodstream.

There is also some caffeine in the Green Tea Extract which can help with improving the body’s metabolic rate for fat-burning.

Overall, these two ingredients are good thermogenic ingredients but we are still skeptical about its effectiveness because it seems that it mainly depends on caffeine for fat-burning.

We would recommend more fat-burning ingredients in the formula to provide a more effective and complete weight loss blend.

Slender Blend Side Effects

Potential Slender Blend side effects include:

  • Bloating
  • Gas
  • Stomach Upset
  • Nausea
  • Jitteriness
  • Headache
  • Sleeplessness

These potential side effects could be from sensitivity to lactose in the whey protein, sucralose (the sweetening agent), or the caffeine from the Protein World Thermogenic Blend.

If you experience any of these Slender Blend side effects, stop the use of the product immediately.

If you have any medical conditions or allergies, consult your physician before taking Slender Blend protein powder.

Slender Blend Weight Loss Results

Slender Blend is very enticing as a meal replacement protein powder that promises to help you lose weight by lowering calorie intake.

To lose weight, you must burn more calories than you consume. Since exercise doesn’t burn a lot of calories, it’s given that you must reduce the number of calories you consume to cause weight loss.

Each serving of Slender Blend is approximately 200 calories if you’re mixing it with almond milk. If you replace two meals a day with Slender Blend and have a small meal, you could be clocking in at less than 1000 calories which is extremely harmful to your body.

Also, even though Slender Blend contains nutrients you need from a meal, it does not give you the satisfaction of a meal. The whey protein may help you feel full, but it doesn’t last for long and you may find yourself hungry again after having a shake.

This dissatisfaction could lead you to snack and potentially binge which could cause you to gain weight from Slender Blend.

Does Slender Blend help you lose weight?

Slender Blend alone will not help you lose weight. It’s still dependent on you to restrain yourself from snacking and making healthier food choices.

How much weight can you lose with Slender Blend?

If you are taking Slender Blend along with a calorie-restricted diet and exercise, you could lose up about 3 kg a month at a healthy rate.

Slender Blend Boots & Tesco

You can buy Slender Blend online from the Protein World website or from local retailers such as Boots, Superdrug, Holland and Barrett, and Tesco.

Slender Blend Review

Slender Blend Reviews – Does Slender Blend Make You Gain Weight?

Overall, there is potential for Slender Blend to make you gain weight.

The meal replacement shakes are only 200 calories per serving. While it is packed with protein and nutrients, it may not be enough to satisfy your cravings for food.

This may lead to excess snacking and binging on top of using Slender Blend protein shakes which can lead to weight gain from the extra calories.

Also, there are only two thermogenic ingredients in Slender Blend protein. The ingredients are good but don’t support a complete whole-body fat burn.

You might be better off having a cup of coffee or tea every day if you’re depending on Slender Blend to help you burn fat.

The Slender Plan requires that you stick to their products for a whole month to lose weight. You’d have to spend £150 a month to stay on that weight loss plan that you have little control over.

We wouldn’t recommend replacing meals with protein shakes but eating food you want in moderation with consistent exercise. Changing your habits is a sure-fire way to shred fat and keep it off for the long term.

If you really want an effective boost for fat-burning, we would recommend going with a different product that helps suppress your appetite while increasing your metabolism for optimal weight loss results.
