Review: Perfect Lunch Replacement for Consistent Weight Loss! - I am now on my third order of the USN Diet Fuel Ultralean Vanilla Meal Replacement Shake, and it has been a game-changer for my diet and weight loss goals. I use this shake religiously as my lunchtime meal replacement, and it works perfectly. • Keeps Me Full: The high protein content—25g per serving—and added vitamins genuinely make me feel full for longer. This has eliminated my afternoon snacking and greatly aided my consistent weight loss. • Great Taste: The Vanilla flavour is delicious and makes it easy to stick to. It’s simply prepared by adding 2 scoops to cold water. • Nutritionally Sound: It's a convenient, low-calorie way to get my essential vitamins and nutrients. • Convenient & Versatile: This 1kg powdered drink mix is quick to prepare and can even be made up as a snack between meals to curb sweet cravings. If you are looking for a reliable, tasty, and effective meal replacement to help support your weight control and weight loss journey, I highly recommend the USN Diet Fuel Ultralean. It’s definitely helped me see consistent results!
Review: My go-to shake and the best tasting I’ve tried - This has become my go-to shake. I’ve tried quite a few meal replacement and protein shakes over the last year, and this is easily the best tasting one I’ve found. I’ve been using it consistently for over 8 months now. I feel full after having it, and it’s fitted really well into my routine alongside regular exercise. I’ve lost over 3 stone during that time, and this has helped me stay consistent and make healthier choices overall. I’ve also found it helps with recovery after gym sessions. I usually mix it with ice, which gives it a really good consistency and keeps it nice and cold, exactly how I like it. It blends well and doesn’t end up thick or gritty. I’ve tried a few other flavours in the range too, but the vanilla is my favourite. It tastes much more natural than a lot of vanilla shakes on the market, which can be overly sweet or artificial. The only small downside is that the scoop can be a bit tricky to find when first opening a new tub, so I tend to keep one from the previous container. Other than that, I can’t fault it and will continue using it.

## Questions & Answers

**Q: is this product Halal?**
A: Are all the flavours halal?

**Q: Does it increase energy levels?**
A: I didn’t personally like the taste of it so I only used it a few times and I wouldn’t say it improved my energy levels

**Q: Can someone give me prep tips. I put 2 scoops in to the USN shaker, filled it with water to near the top. Shook well. It's all lumpy and watery.**
A: I only put one scoop into 200ml of milk in a measuring jug and hand whisk it until smooth. I have an extra drink a day by doing it this way. I found that 2 scoops in 300ml was too thick and lumpy.I am a sixty-six year old female.

**Q: Can you drink tea and coffee with these shakes? Sorry if it sounds like a silly question.**
A: Don’t drink tea or coffee myself but I can’t see what the problem would be

### ⭐⭐⭐⭐ Tastes like vanilla and strawberry is nice, but not 100% Keto friendly
*by H***K on 12 September 2025*

Just tried it today as I am going Keto agan, but this isn't Keto. It tasted okay, however (TMI) I had a bowel movement after wards, so jury is out, not sure its good for my gut condition and IBS. I have ordered the strawberry one. Really a shame Exante aren't doing shakes anymore, as their vanilla Keto was the best. This tastes similar to Exante one, but it's protein. As a meal replacement to get me back onto fasting in general before I do Keto eating, this is a good solution. Has nutrients I need and saves time. WIll do an update later. UPDATE: Srawberry one is really nice.
