What Is RSP TrueFit?

TrueFit is a “Lean Protein Shake” (i.e. a low calorie protein shake) made by a US-based supplement company named RSP Nutrition.

One tub of TrueFit costs around $35-45 (depending on where you shop) and contains 30 servings; it is available via the official RSP TrueFit manufacturer website and Amazon.

The product is essentially just a combination of whey protein concentrate and isolate, with added fiber, digestive aids and greens (among other ingredients).

Consumers are told they can use the shake as a regular post-workout protein shake to help aim muscle growth and recovery, or as a meal replacement for the purposes of losing body fat.

Does RSP TrueFit Work?

Based on our research into this product, we believe it can definitely be used as an effective meals of losing weight – but only if you approach using the product in the correct manner.

Firstly, this is by no means a miracle fat burning protein powder – in fact, it doesn’t contain any ingredients that will boost your metabolism or burn your body fat. Weight loss from this product will come by using it as a meal replacement shake.

In replacing your three daily meals with a serving of RSP TrueFit, you’ll be crashing your daily caloric intake significantly, which will allow you to gradually see weight loss over a period of 3-4 months. This type of diet is called a VLCD and is known to be effective, but difficult to stick to – ensure you have the willpower before embarking.

Are There Any RSP TrueFit Reviews From Customers?

We have found the following RSP TrueFit review testimonials via customers online:

Started drinking these a week ago. It’s the best-tasting protein shake I’ve ever had, and it’s very easy to mix. As a meal replacement, one shake will leave you feeling satiated for about two hours, and even if you drink three a day, which adds 75 grams of protein to your daily intake, it comes out to less than $5. So it tastes great, is full of protein and vitamins, and is an economical meal replacement.

I was looking forward to trying this protein shake. It arrived today and I decided to carefully read all the ingredients as I have read that many similar products contain lead! Under the NUTRITIONAL VALUES box there was a warning that RSP Nutrition TrueFit contains ingredients that are know to cause birth defects and harm the reproductive system!!!! THERE IS NO INDICATION OF WHAT THAT COULD BE. I suspect it’s lead as California mandates labels like this for products that contain lead. This was not advertised on Amazon’s website. Misleading advertising by RSP!

Our Final Verdict On RSP TrueFit

To conclude our RSP TrueFit review, we recommend this product. Though it isn’t going to burn away your body fat any time soon, it’s a decent meal replacement / food alternative which can help you see gradual weight loss.
