GNC Lean Shake Review - Does This Meal-Replacement Product Really Work? Are high price and unpleasant taste deal breakers?

Editor's Review: 2.9 / 5.0

gnc-lean-shakes-product-imageDiet products either work or they don’t. Period. Let’s find out which one GNC Lean Shakes is. We took the time to write a detailed review, examining the ingredients, side effects, customer service and clinical research. Moreover, we focused on dozens of dieter comments posted online. Finally, we condensed and refined to give you the bottom line.

EDITOR'S TIP: Combine GNC Lean Shake with a proven fat burner such as Leptigen for better results.

What You Need To Know

To start, GNC Lean Shakes come in flavors like chocolate peanut butter, cookies & cream, and French vanilla. The ingredients used in this shake powder include milk protein concentrate, nonfat dry milk, creamer, natural and artificial flavors, sucralose, acesulfame potassium and a vitamin and mineral blend. This product is claimed to support lean muscle mass, fuel the metabolism and encourage healthy cholesterol levels.  These can be used in place of meals and you are encouraged to drink it twice daily. Simply add two scoops of powder to eight ounces of cold water. Each provides 180 calories, eight grams of fiber and nine grams of protein. When used daily, GNC Lean Shakes can support weight-loss. You can make it at home to travel with you anywhere.

GNC Lean Shakes have been available since 2009 and are sold online, as well as in common GNC store locations. These shakes provide a significant amount of fiber and are available in several different flavors, but read on…

Expensive – “Way to High?”

The first problem we encountered with GNC Lean Shakes ingredients were price. According to our Research Editor, “GNC Lean Shakes are a very pricey product when you consider the fact that a single container provides 16 servings, which is only enough for 8 days. The price tag is $34.99, which means you will spend almost $140 a month.”

“This tastes horrible! And the jug only lasted me a week!,” said one customer.

Another stated, “I can’t afford this. There are cheaper protein supplements that contain more protein.”

Scroll below for one of the best products we’ve seen in 2015.

Unpleasant Taste – “Another Concern”

There are literally dozens of customer complaints regarding the taste of the GNC Lean Shakes. For instance, one user said, “Tastes too sweet with artificial sweeteners.”

Another complained, “This is the worst tasting powdered meal replacement I’ve had.” Yet another said, “Taste is HORRIBLE! Very Chalky! Not worth the price.”

According to our research, if there is one facet of a supplement or diet program that is very troublesome (unpleasant taste, serious side effects, high price) the probability of long-term weight-loss success is very low. If GNC Lean Shakes are difficult to swallow, this could be problematic.

The Science – “Clinical Support?”

According to the official website, GNC Lean Shakes are “clinically proven” to aid with weight-loss. However, we at DietSpotlight couldn’t find any documented research to support these claims as they apply expressly to this product. There are plenty of similar formulas on the market with scientific support, as long as the dieter maintains a low-calorie diet plan. We must see real evidence concerning the supplement and weight reduction in order to believe promises.

The Bottom Line – Do GNC Lean Shakes Work?

Hmm, what should be say about this one that’ll sum it up for you? We appreciate that GNC Lean Shakes provide a significant amount of fiber to assist with regularity and appetite suppression. However, we have reservations about this supplement because it’s not backed by solid clinical research. Furthermore, the amount of protein in a serving of this is quite minimal (only 9 grams). Also, if you used this it as directed, twice a day, it would cost you nearly $140 a month. Not to mention, there are countless customer complaints about the taste.

If you want to slim down and rock your best body, we encourage you to choose a diet supplement that is both affordable and backed by real clinical results. It helps if you don’t have to worry about dealing with bad taste.

Among the best products we’ve seen in 2015 is one called Leptigen. This diet formula contains a unique blend of four ingredients, which have been shown in documented clinical studies to improve fat loss and increase metabolism. We are unable to find any discussion of harmful adverse effects and dieter reviews posted on the web indicate people are seeing wonderful results.

Also, the company behind of Leptigen is confident enough in their product to offer a Special Trial Offer, good sign.

A popular product distributed by GNC (General Nutrition Center) is the GNC Lean Shake. This is said to be one of the products of this well-known and trusted supplement industry designed to promote weight loss. Not surprisingly the company is in good BBB standing. The GNC Lean Shake is a healthy meal replacement proven effective for weight loss. The shake increases your muscle mass and promotes good metabolism. The meal and exercise plan is said to be scientifically-researched and designed.

List of Ingredients

One serving of a GNC Lean Shake is a rich source of sodium, potassium, phosphorous, Vitamin A, magnesium, calcium, folic acid, iodine, and biotin. Other ingredients include the following: saturated fat, soluble fiber, cholesterol, dietary fiber, sugars, protein, Vitamin E, Vitamin C, iron, thiamin, Vitamin B-6, riboflavin, niacin, Vitamin B-12, pantothenic acid, copper, zinc, selenium, manganese, chromium, and molybdenum. A comprehensive list of ingredients is available through the GNC website. The product contains milk, corn, and soybeans.

Product Features

GNC Lean Shakes come in a few different flavors. They include vanilla bean, Swiss chocolate, cookies and cream, and strawberries and cream. As a meal replacement shake, users are instructed on the label to take two scoops (48 grams) and mix it well with 8 ounces of cold water. This is done twice daily while following the included meal and exercise plan. GNC Lean Shakes are clinically proven. According to the official GNC website a randomized study of 98 healthy participants studied and compared the effects of those merely eating 1,500 calories per day versus those on the Lean Shake plan (1,500 daily caloric intake, regular exercise, and the two lean shakes daily). They conducted this study over twelve weeks. Results showed that participants on the Lean Shake plan lost nearly twice as much total weight (7 lbs versus 4 lbs) and had four times greater reduction in cholesterol. A 1.7 lb. bottle of Lean Shake costs $29.99 through the official GNC website. It is $23.99 when purchased with a Gold Card. It is also possible to purchase this product in twelve packets for $23.88 ($19.10 with Gold Card).

    I gained weight, was horribly bloated & extremely gassy. I ate a 1200 calorie diet. Low fat, carbs, sugar & dairy. Loved the taste. After 8 weeks stopped the shakes & lost the weight, bloat & gas went away.



    I am having this same problem right now. I think it tastes great, but I’m feeling kind of crummy!



    I have been using GNC Total Lean natural for about 2 weeks. First of all, it is delicious! I make it into a smoothie by adding ice, banana and water. At first, all was well but now I notice extreme bloating and bouts of severe diarrhea which is often without warning and hard to control. Unfortunately, I will not continue with this as the side effects are unpleasant.

    I’ve been using the Lean 25 shake since Friday and I love it, especially the French Vanilla. I bought the Rich Choc as well, but it leaves an after taste! It’s kept me full and I do 2 scoops with 1% milk adding ice and mixing in my Nutribullet. Gives an excellent consistency and I am full. I do a shake for breakfast and lunch with snacks in between and I’ll eat a meal for dinner!

    I’ve started using the Lean Shake about three weeks ago regularly and have lost about four inches. I am very happy and will continue, however, I eat my one meal at lunch instead of dinner.





  • 26

    I tried four flavors of the shakes and ended up returning all of them. I couldn’t get past the smell or texture of the shake. It was quite disappointing.


  • 27

    what food could i eat tha would not interfere with the lean shake


  • 28

    I have been using this shake for a few months and love it! I am prior military and my husband is Active Army and we workout a lot and use this as a meal replacement once a day, instead of the recommended 2. I have lost the10 pounds weight i’ve wanted to and continue to use the shakes to maintain. I use the Lean Shake 25, which is 25 grams of protein and it works better than the regular LS because of the added protein. Good luck on the weight loss!

    Is there gluten in this product?


  • 32

    I just started using the GNC Lean Shakes, in the Swiss Chocolate flavor. I noticed in some reviews that the pwder did not have a good texture. I bought the bottles. I thought it was a little too sweet though good chocolate flavor and nice creamy texture. Though I will use what I bought, I don’t think I will purchase more Swis Chocolate flavor as I don’t want SUCH a sweet shake. I may try a different flavor before I totally discontinue using it however. Good luck to all :o)

    I dislike the taste and after looking at all of ingredients, there is creamer, and many additives I cannot pronounce.


  • 36

    I am wondering how long the normal person stays on this product and is it a way of life for them now or did it jump start you and then you could regulate your intake?



    I started using GNC Lean Shake a year ago and usually have 1-2 shakes most days for breakfast and lunch along with some fruit or greek yogurt. I lost 45 lb in 9 months and maintained it through the holidays. I find the vanilla and cookies and cream the most tastey. If I creep up on the weight, I just fill in with this again to get back on track.

    Did u work out to using the shakes
