What You Need To Know About 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 five different flavors, which include chocolate, vanilla, strawberry, banana caramel and café latte. 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 is simply 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…

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 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.

Lack of Availability – Another Concern

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 in fact taste bad to numerous people and is difficult for many dieters to find, this could be a serious dilemma.

The Science Behind USN Diet Fuel Ultra Lean – Any?

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.

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 it’s not backed by clinical studies. 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 supplement that is readily available online, contains clinically proven ingredients and comes with excellent customer service.

Among the best products we’ve seen in 2016 is one called Leptigen. Its formula is a proprietary blend of four key ingredients, which have been shown in documented clinical studies to help speed up fat loss and boost metabolism. We can’t pinpoint any talk of negative adverse effects and dieter comments found on the web show people are seeing substantial results.

The makers of Leptigen are so excited about their product they’re offering a Special Trial Offer, which is a positive sign.

What You Should Know About USN Diet Fuel Ultra Lean

There are plenty of meal replacement products at your disposal these days. As you are likely aware, these supplement shakes and bars are intended to be eaten in place of a meal, which includes breakfast, lunch, and dinner. Often it is recommended that you eat the meal replacement formula instead of breakfast or lunch. This way you can still eat a good dinner, but decrease your daily calorie intake. USN Diet Fuel Ultra Lean is one product that falls into this category. It is a powder formula that comes in flavors like chocolate, pina colada, vanilla, chocolate mint, and strawberry. The cost of this supplement is around $40 per canister.

Product Features: USN Diet Fuel Ultra Lean

USN Diet Fuel Ultra Lean is intended to be consumed in place of one or more meals each day. This is a low-calorie shake, but it does contain a number of vitamins and minerals. This way you can still receive the nourishment you need, but without a great deal of fat and calories. This powder is easily combined with water, just as most meal replacement shakes are. It should encourage a feeling of satiety.

You receive 200 calories from a single USN Diet Fuel Ultra Lean shake. This product contains ingredients and nutrients like B vitamins, folic acid, whey protein, calcium, potassium, vitamin a, chromium picolinate, soy protein, and magnesium. The proteins used in this supplement powder should help stave off cravings and hunger pangs.

Advantages of USN Diet Fuel Ultra Lean

  • This product contains plenty of vitamins and nutrients.
  • USN Diet Fuel Ultra Lean is rich in protein.
  • This supplement may help suppress food cravings.

Disadvantages of USN Diet Fuel Ultra Lean

  • There is no money-back guarantee for this product.
  • No key ingredients are used to burn off fat.
  • Some people might not be willing to consume a shake instead of meals.
  • A pill or capsule supplement is more convenient.

Conclusion

One thing we noticed about USN Diet Fuel Ultra Lean is that each serving only contains 200 calories. While this might be good for weight loss, you should keep in mind that you need at least 1200 calories per day. Therefore a serious drawback to this supplement is that it might leave you feeling very hungry. Then there is the lack of fat burning ingredients. Clearly USN Diet Fuel Ultra Lean shakes are not intended to boost the metabolism or assist with fat burning. This factor alone might turn some dieters away.

This shakes comes in different flavors: vanilla, chocolate, strawberry, banana caramel and cafe latte.

You would need to go over the formula with his tp ensure no conflict with his condition or current medications.

I was wondering when I should take this supplement, I go to the gym around 4 times a week.

USN Diet Fuel Ultra Lean is intended to be consumed in place of one or more meals each day. Basically take it when you would normally eat.

I am a 30year old women wanted to lose weight so I started USN diet fuel ultra lean+USN cla pure 1000+phedraphedra-cut lipo xt I exercise everymorning run (hard)

This is warned against from some dieters.

I just wonder if you can drink ultra lean protein shake without training/exercise or do you have to have workout when drinking protein? If I have to workout when drink protein which would be best to drink protein before or after workout? Also with this protein how long would you recommend to workout for? As I only want to tone up my body that all….

Hi, Anni. You can take this without exercise however your chances of success increase if you maintain regular exercise. Take it before your workout. A 30 – 60 minute daily workout is recommended. Good luck, keep us updated.

Hi, so i started taking ” Low GI diet fuel ultralean nutrition shake” but i am worried . I just wanted some answer. I am a women of 20 yrs old. I exercise everyday(fitness)except on thursday and saturday for 1hr 30. Is it suitable for me? Will i gain weight or mass cause this is not my goal. Please i want some answer .

This product does claim to promote lean muscle mass which could cause your weight to increase because muscle weight more by volume.

i started this meal replacement on Tuesday. I am following my own 8 week plan, which includes 30 min interval training 6 days a week and 2 days a week lifting weights. Eating clean and using the food diary on myfitnesspal and no cheat days. It’s only a 8 weeks plan time to get strict, I just want to make a difference. Anyway back to the product. I have the chocolate one and find no problem at all with the taste. I only have one scoop per serving, with 300ml of water. I shake it up and leave in fridge for a good 20 minutes as it thickens and reminds me of McDonald’s milkshakes smile I also tried for the first time today, using my daughters mr frosty, mixing a scoop with the crushed ice – amazing! Even more so like McDonald’s milkshake haha smile so yeah I’m enjoying this product. But like I said only been on it two days, and although I have had a sneaky weigh in I have lost 2lbs already but that is everything on doing combined.

Hello, I’m a 19 year old transman and I weigh 56 kg, would really be happy if I can loose weight and get rid of my butt. I was wondering if using the diet fuel ultralean nutrition shake, two meals a day and going to a gym for an hour and half everyday, would I loose 10-15 kgs in two months?

Possibly, tell us you you like it.
