PhD Diet Whey Quick Summary

PhD Diet Whey is a protein powder that claims to have additional ingredients that support fat loss.

However, there is little to no research to support that CLA and L-Carnitine actually work to help weight loss. There is too little Flaxseed to promote appetite suppressing and Green Tea Extract is the only thermogenic ingredient.

PhD Diet Whey is really just another protein powder trying to be a fat burner.

If you want a zero-calorie supplement that will effectively suppress your appetite all day and also boost your metabolism for powerful fat burning, check out our best fat burner review.

What is PhD Diet Whey good for?

PhD Diet Whey states that it is good for fat loss or maintaining a lean physique year-round. It’s also ideal for men and women following a weight management nutritional plan.

PhD Diet Whey claims that it contains the following:

  • Premium high protein blend
  • CLA & L-Carnitine
  • Green tea extract
  • Low sugar

This diet whey protein markets itself as being able to provide high protein supplementation with fat-burning benefits.

But can PhD Diet Whey really help you lose weight?

In this PhD Diet Whey review, we’ll take a full look at the fat-burning ingredients inside this protein powder and see if actually helps you with weight loss.

PhD Diet Whey Ingredients

PhD Diet Whey Protein Ingredients

Here are the weight loss ingredients in PhD Diet Whey Protein:

  • Flaxseed
  • CLA (Conjugated Linoleic Acid)
  • L-Carnitine
  • Green Tea Extract

PhD Diet Whey claims that along with protein, these ingredients will help support and assist in fat loss.

Next, we’ll be looking at each of these ingredients to see if they can actually help with weight loss and if it’ll be effective enough to work for you.


Flaxseed is a modern superfood that is known for its variety of health and nutrient benefits.

It is high in omega-3 fats and rich in dietary fiber. Flaxseed may also be able to help lower cholesterol and lower blood pressure.

Flaxseed’s high fiber content is often used for weight control. A research study found that the addition of ground flaxseed fiber to a beverage helped reduce hunger and increased feelings of fullness.

However, the amount of flaxseed fiber added to the beverage was 2.5 grams. The amount of Flaxseed fiber in PhD Diet Whey is about 900 milligrams per 2-scoop serving, not counting the flaxseed oil content.

Flaxseed oil makes up almost half of the Flaxseed powder in PhD Diet Whey. Flaxseed oil does not provide the full health benefits of flaxseed because it lacks the fiber content.

This is an okay ingredient in PhD Diet Whey. Flaxseed is good for suppressing appetite and reducing hunger with its fiber content, but the amount of Flaxseed in PhD Diet Whey is not enough to support weight loss.

CLA (Conjugated Linoleic Acid)

Conjugated Linoleic Acid or CLA are fatty acids that work on a molecular signaling system in the body called PPAR. The PPAR system is somewhat related to fat burning, steroid signaling, inflammation, and glucose metabolism.

Some theories suggest that CLA’s effect on PPAR can lead to fat loss. However, all of the human studies done show that CLA is unreliable for fat-burning and is too weak to prove any weight loss benefits.

CLA is a bad ingredient in PhD Diet Whey because it does not have any studies supporting that this ingredient is effective for weight loss support.


L-Carnitine is the resulting compound produced by the body from lysine and methionine. It’s often found in beef and other meat products.

There is some suggestion that L-Carnitine may reduce fatigue, increase energy, and slightly reduce muscle damage during exercise. However, these claims are not well supported.

L-Carnitine has also been marketed as a fat-burning ingredient. But it seems that the minor fat loss involving L-Carnitine may be due to the reduced fatigue that led to more physical activity.

There aren’t any notable fat-burning effects on the body when L-Carnitine is supplemented.

This is not a good ingredient for weight loss in PhD Diet Whey because there is no strong evidence to prove that L-Carnitine is an effective fat-burning ingredient.

Green Tea Extract

Green Tea Extract comes from the green tea leaves, which contain a large number of antioxidants or also known as catechins.

This ingredient helps with weight loss due to the combination of catechins and caffeine in it.

Studies show that catechins and caffeine in Green Tea Extract help regulate hormones in the body for thermogenesis. The Green Tea Extract boosts thermogenesis to help your body burn calories better so you can lose weight.

This is a good ingredient to have in PhD Diet Whey to help you increase fat-burning in your body and get to your goal weight faster.

PhD Diet Whey Protein Ingredients Summary

Here’s what you need to know about PhD Diet Whey Protein ingredients:

  1. Flaxseed – as a fiber extract, it’s good for reducing hunger, but there is too low of a dose to feel the appetite suppressing effects
  2. CLA (Conjugated Linoleic Acid) – unreliable and not supported to assist in fat-burning
  3. L-Carnitine – no strong evidence to support any weight loss benefits
  4. Green Tea Extract – good for increasing thermogenesis for fat burn

Overall, there is only one good ingredient for weight loss in PhD Diet Whey and it’s Green Tea Extract. Flaxseed could be a good for fat loss, however, there isn’t enough of it in the formula to be effective.

The other fat-burning ingredients are just advertised for fat loss, but there is no strong evidence to support their effectiveness.

With only one fat-burning ingredient in PhD Diet Whey, it doesn’t seem like this protein powder will do much to support weight loss. It could be improved with more fat-burning and thermogenic ingredients to maximize weight loss results.

Diet Whey Protein Weight Loss

Diet Whey Protein – Weight Loss

PhD Diet Whey Protein can help with weight loss if used in a balanced diet.

It contains about 200 calories per serving, which is used as a meal replacement would help keep daily calorie intake low. Burning more calories than consumed will lead to a calorie deficit and result in weight loss.

We don’t recommend using PhD Diet Whey alone as a fat burner due to the mostly ineffective fat-burning ingredients in the formula.

PhD Diet Whey Bars

The main difference is that the PhD Diet Whey Bars only contain L-Carnitine as its weight loss ingredient, instead of the 4 ingredients in the protein powder.

PhD Diet Whey Bars are good for a snack or a protein boost but don’t rely on it to give you superior fat burning, even though it says “Diet” in the name.

PhD Diet Whey

Does PhD Diet Whey help lose weight? – Summary

In conclusion, no, PhD Diet Whey cannot help you lose weight if you’re relying on it for its fat-burning ingredients.

PhD Diet Whey is a high protein and low calorie protein shake that claims to be able to assist fat loss.

The fat-burning ingredients featured in PhD Diet Whey like L-Carnitine and CLA have little to no evidence of being able to support weight loss. There’s not enough Flaxseed to provide appetite suppressing and Green Tea Extract seems to be the only good thermogenic ingredient in it.

Due to the ineffective fat-burning ingredients, it makes PhD Diet Whey just another protein powder.

Would we recommend PhD Diet Whey? No, we would not.

The only way PhD Diet Whey can help you lose weight is if you strictly replace your meals with PhD Diet Whey and reduce your calorie count. You have to rely on the whey protein to make you feel full and reduce your appetite throughout the day.

However, for most people, this doesn’t work for them and can often lead to people snacking more and overeating. Using protein powders as a meal replacement doesn’t replace the satisfaction of having a healthy meal.

We would recommend using a fat burner with plenty of effective thermogenic ingredients that will boost your metabolism and suppress your appetite all throughout the day.
