Overview

What is USN Diet Fuel Ultra Lean?

USN Diet Fuel Ultra Lean is a “nutrition shake” for women and men that is claimed to promote weight loss and help with lean muscle maintenance. It is available in three different flavors, which include chocolate, vanilla, and strawberry cream. Since this is a company based in the UK, it does not look like this supplement is available to people in other parts of the world, such as the US.

The primary ingredients found in this supplement powder include; Whey Protein Concentrate, Soy Protein Isolate, Milk Protein Isolate, Garcinia Cambogia, Micronized Milk Mineral Complex, Inulin, and various vitamins and minerals. Each scoop/serving provides 25.4 grams of protein. USN Diet Fuel Ultra Lean merely is added to a glass of cold water and then consumed.

It looks like USN Diet Fuel Ultra Lean was released in 2013. This product contains a decent amount of fiber per serving, and there are some positive comments posted online. Also, this product can be used at any time, but read on…

Taste

Is Bad Taste a Concern?

“You will notice quite a few customer complaints online regarding the actual taste of USN Diet Fuel Ultra Lean shakes. This is never a good thing because how will you stick to these protein shakes if you can’t stand the taste?,” says our Research Editor.

According to one customer, “Too sweet and sickly for me. Could only get through half of it before giving up. Six hours later I still have a sweet chemical aftertaste. Regret buying this. Will look for a better alternative.”

“I thought it tasted horrible and no matter how much I mixed it in my shaker it just didn’t blend well. Lumps of powder. Terrible stuff” said another user.

Availability

Lack of Availability

It looks like USN Diet Fuel Ultra Lean is only available to those living in the UK. Therefore dieters from other countries will certainly have a difficult time trying to get this supplement. One person stated, “Where can I buy this?? It doesn’t seem to be available online.”

Another dieter said, “Only seems to sell in the UK. Oh well, on to a different product.”

The intensive research we’ve done has shown if there is one particular facet of a supplement or diet program that is especially bothersome (a painful/difficult exercise routine, bad taste, lack of availability) the odds of prolonged success are not good. This means if USN Diet Fuel Ultra Lean does taste bad to numerous people and is difficult for many dieters to find, this could be a serious dilemma.

The Science

The Science Behind USN Diet Fuel Ultra Lean

Like most protein powders, USN Diet Fuel Ultra Lean provides a significant amount of protein per serving. However, we were unable to find any clinical studies that support the claimed effectiveness of this supplement. At DietSpotlight, we need to see solid research that backs up the weight loss claims.

What Users Are Saying

“I’m on my second tub of this, used for office work so I don’t gain to much weight sitting in a chair for 10 hours a day a month or so at a time. Ideal for a lunch replacement. It really does fill you up and tastes really nice.”

“The taste is unfortunately disgusting and the powder dissolves only very badly in milk. Dissolved in water it does not taste very good. After drinking it, I had to burp it about 1-2 hours later, regardless of whether I had eaten it on an empty or filled stomach – disgusting.”

“Very bland and powdery in taste. I always add some strawberries and buttermilk to give it a bit better flavour.”

Bottom Line

The Bottom Line: Does USN Diet Fuel Ultra Lean Work?

So, should you run out and buy USN Diet Fuel Ultra Lean? Well, we like that USN Diet Fuel Ultra Lean provides a good amount of fiber and there are some positive comments about it online. But we have some reservations about this supplement because clinical studies do not back it. Furthermore, we’re concerned about this product’s bad taste and lack of availability.

If you’d like to drop more weight, then we encourage you to go with a system that is backed by multiple clinical studies and can help you meet your personal goals.

Among the best weight-loss programs we’ve seen this year is one called Noom. This system gives its users everything they need to start losing weight the healthy way, including personalized meal plans, interactive support groups, human coaching, and so much more. Plus, it all comes in an easy-to-use app so you can track your progress from anywhere.

The makers of Noom are so excited about their program that they’re offering a free trial, which is a positive sign.
