GNC products are everywhere in popular diet culture, and Lean Shakes is one of their newer products. GNC claims that Lean Shakes reduce weight in combination with a reduced calorie diet. While this may be true, any consistent reduction in calories will lead to weight loss, and there does not appear to be anything proprietary this product that makes it a superior meal replacement.
Still, we asked our team of researchers to look into it. They examined the full list of ingredients, any potentially related side effects, clinical research, and customer service (by checking out user reviews online). We then condensed that information to give you all the facts about GNC Lean Shakes.

GNC Lean Shakes Video Review
What are GNC Lean Shakes?
GNC Lean Shakes is a brand of nutritional meal replacement shakes that were developed to help individuals struggling with weight loss to consume a large number of vitamins and minerals while consuming a small number of calories.
The shake includes 24 vitamins and minerals. GNC claims that the high fiber content (8 grams) and the protein source, whey protein isolate, can help dieters feel fuller and more satisfied when replacing a meal with the GNC Lean Shake.
These shakes exist in some flavors to please a wide range of users. GNC Lean Shakes are intended to suppress the appetite during the day to help with weight loss goals. To date, the product has received consistently decent results with some customers claiming to experience reduced hunger for two to three hours after consuming the shakes.
Reports on the taste of this meal replacement shake are mixed. Some purchasers love the flavors, and some say they are terrible. The flavor with the highest number of complaints seems to be vanilla. Some users have also expressed a dislike for the consistency of the shake. Some users said that the shake seemed thin and watered down. The consistency can be altered, however, to an individual’s taste by adding water if a thinner consistency is desired or adding fruits like banana or avocado for a thicker consistency. Shakes can also be blended with ice to create a thicker texture, and more protein powder may be used as well.
The flavors available for GNC Lean Shake can also be added to milkshakes, smoothies, or any other beverage that can make the taste more palatable to an individual. Some consumers have also expressed that the lightly colored flavors have a naturally thin consistency when compared to the darker colored flavors like swiss chocolate and mocha.

Clearly, this shake is not lactose free, and we cannot find any indication that is is gluten free either.
GNC Lean Shakes Nutrition Facts
One bottle or 14 fluid ounces of a GNC Lean Shake represents approximately one serving of the beverage. In one serving, consumers can expect to find the following:
GNC Lean Shakes also contain 25% of the daily value of the vitamins and minerals riboflavin, niacin, B-6, folic acid, B-12, Biotin, Phosphorus, Iodine, Magnesium, and Chromium. Consumers who are seeking to lose weight with this product will generally be placed on a lower calorie diet than the standard 2000 calorie diet and should remember to adjust these values to their specified daily caloric intake. Some of the benefits of these specific vitamins and minerals include:

Effects of Protein in GNC Lean Shakes
Whey protein powder isolate is one of the key active ingredients in the GNC Lean Shakes, and its purpose is appetite suppression. This whey protein has only a small amount of fat from animal sources, and provides almost 90% more protein than other hydrolysates. Hydrolysates are proteins that have been broken down for better absorption by the muscles. This protein isolate has been shown by many studies to efficiently build muscle mass and cause the body to feel full with very little foods, according to research published in Nutrition & Metabolism and other medical journals.
By consuming this protein in supplemental or natural form, those seeking weight reduction become six times more likely to lose fat and replace that fat with lean muscle mass through a consistent workout plan.
One serving of the GNC Lean Shake meal replacement yields nearly a fourth of the daily requirement for protein. For those attempting to limit daily caloric intake to under 1500 calories (as is the case with many diets) a single serving of the meal replacement yields over half of the total daily requirement for protein.
By substituting the meal replacement shake for at least two meals each day, consumers may successfully ease cravings while consuming the entire daily requirement of protein before dinner.
Good or Bad Calories in GNC Lean Shake
Each serving of a GNC Lean Shake contains about 180 total calories and 20 calories from fat. The calories in the GNC Lean Shakes are derived primarily from the category known as “good calories,” meaning that they have a higher nutritional value for their caloric worth.
The calories in GNC Lean Shakes provide the human body with the fuel it needs to complete basic tasks during the day while the shake’s ingredients are supposed to help the body to burn fat stores in addition to calories.
By using this product as a meal replacement for the first two meals of the day, consumers can guarantee that they are consuming only 360 calories in addition to the number of calories eaten during dinner meals. This should create a sufficient calorie deficit to assist with weight loss.
What Does a GNC Lean Shake Do?
GNC Lean Shakes help consumers to experience consistent weight loss by helping to limit the number of calories consumed each day. Weight loss is accomplished by a simple equation that requires that the overweight individual consume fewer calories than their bodies burn in one day. By replacing one or two meals per day with a GNC Lean Shake, consumers may increase the odds that their daily caloric intake will be less than their daily caloric output, thus resulting in gradual weight loss.
Can GNC Lean Shakes be Meal Replacements?
Meal replacement shakes are intended to be a lower calorie, high nutrition alternative to preparing a meal. However, it is important to get enough calories, protein, and nutrients from your shake replacement, and not all powdered protein drinks fill those needs. According to the Journal of Obesity, meal replacement shakes can help you lose weight if they are made right.
Meal replacement shakes should contain:
Around 300-400 calories
15-25 grams of protein
A minimum of 5 grams of fiber
10-13 grams of healthy fats
GNC Lean Shakes fall a little short in the calorie department, weighing in at around 200 calories per serving. However, with a whopping 8 grams of fiber and 25 grams of protein GNC Lean Shakes can be a good meal replacement for those on a weight loss diet plan.
Does It Work?
Do GNC Lean Shakes Work?
If you take on the question of whether or not GNC Lean Shakes works for weight loss, you have to look at the research into meal replacements simply.
Meal replacement shakes, and other similar products can be an effective means of reducing calorie intake and if you stick with a healthy diet and exercise plan, promotion of weight loss. By now it is no secret to anyone who is trying to lose weight – exercise and good nutrition combined with a reduction in calories is the best way for most of us to obtain weight loss goals.
Now, remember that this is the case for meal replacements, not just GNC Lean Shakes. No research sets this specific product apart from the competition.
Although consumers who used the GNC Lean Shakes have reported weight loss, the product has also received complaints of decreased energy for individuals with very active daily lives. Replacing two meals per day with the GNC Lean Shakes deprives very active people of the caloric intake that their bodies require continuing current activity levels or metabolism in general.
GNC Lean Shakes Side Effects
Side effects that have been reported by individuals using the GNC Lean Shakes as meal replacements include:
Mild headaches and migraines
What about breastfeeding moms? Can they use GNC Lean Shakes? According to the Korean Journal of Pediatrics, food restriction is not needed for mothers.
Nutritionists warn against using meal replacement shakes for kids, though. Young children have different nutritional needs than adults and may be more sensitive to ingredients as well. Meal replacement shakes should only be used occasionally for teens and should be formulated for children. It’s probably prudent to avoid meal replacement shakes for kids who have not yet reached puberty.
GNC Lean Shakes Benefits
On the other side of the coin, some key benefits of consuming GNC Lean Shakes, or a similar meal replacement product, daily, as reported by the Nutrition Journal, could include:
Improved digestion and regularity
Increased weight loss
Improved nutrition intake
Regulation of blood sugar
Increased satisfaction from small meals
Is There a GNC Lean Shake Alternative?
There are several shakes that compare to GNC Lean Shakes and can be used as an alternative to the meal replacement. The meal replacement industry is very lucrative, and the competition in this area has caused the developers to create better-tasting products with improved nutrition.
Alternative meal replacement shakes can also be created at home. By combining a liquid multivitamin with a scoop of whey protein isolate and a combination of tasty fruits, those seeking a meal replacement can make a comparable shake from the comfort of home.
When creating a GNC Lean Shakes alternative from home, however, be sure to measure the quantities of the vitamins and fruits that are included to ensure that the calorie count for the shake remains low. Some fruits, oils, and vegetables contain a high amount of good fat and calories that can easily eliminate any benefit gained by replacing the meal.

What Users Are Saying
“I am allergic to a LOT of things, and I was very skeptical about about buying this but overall very happy I did. I didn’t feel sick, gassy, bloated or constipated after using this (side affects other brands have caused). I also lost 15 pounds and this satisfies my cravings throughout the day. Will order it again and the taste isn’t bad at all.”
“I tried 4 different ways making a shake with this and gagged every time.”
“It’s not bad but it’s not good either. It’ll definitely make you feel full throughout the day (depending on your hunger) but the taste isn’t the best. For that price you could go to a GNC and get something better.”
The Bottom Line – Do GNC Lean Shakes Work?
Hmm, what should be said 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 $131 a month.
If you want to slim down and rock your best body, we encourage you to choose a system that is both personalized and backed by real clinical results. It helps if you don’t have to worry about dealing with tons of supplements, health books, or weight loss calculators.
