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.

GNC Lean Shakes Flavors and Taste

These shakes come in several flavors and can be customized to suit the consumer’s individual tastes. The GNC Total Lean Shake 25 comes in several flavors:

  • Rich Chocolate

Reports on the taste of this meal replacement shake are mixed. Some purchasers really 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.

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:

  • Riboflavin increases blood flow and energy production.
  • Thiamin improves cardiovascular system health and blood flow.

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. [4]

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.

Good or Bad Calories in GNC Lean Shake
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 just 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 Prevention magazine, meal replacement shakes should contain:[5]

  • 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. [6]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. There’s no research that sets this specific product apart from the competition.

Do GNC Lean Shakes Work
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.

Side Effects

Are There Side Effects to Worry About When Consuming GNC Lean Shakes?

Side effects that have been reported by individuals using the GNC Lean Shakes as meal replacements include:

  • Mild headaches and migraines
  • Diarrhea
  • Constipation
  • Nausea

What about breastfeeding moms? Can they use GNC Lean Shakes? According to babycenter.com, here is the deal:  “If you’re breastfeeding, you’ll want to use meal replacements only to provide a healthy option when you need a quick snack or an occasional quick meal (no more than once a day). Relying on liquid replacement meals more often than that won’t provide the calories or nutrients you need for your own health or for nursing.”[7]

safe for mom and baby?

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, on a daily basis could include:

  • Improved digestion and regularity
  • Increased weight loss
  • Improved nutrition intake
  • Regulation of blood sugar
  • Increased satisfaction from small meals [8]

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.

Comparable brands include:

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.

GNC Lean Shakes Results

People who consumed meal replacement shakes have reported varying results, with the majority (and research) saying an average weight loss of one to three pounds per week. [9]

Some users reported a negative response to the taste and consistency of various flavors of the GNC Lean Shake, indicating that the shake had a chalky or stale consistency.

Other users also said temporary side effects including constipation, loose bowels and decreased energy levels.

When taken consistently as a meal replacement for one to two weeks, however, results from GNC Lean Shakes were fairly positive with users reporting an average loss of five pounds per month.

What Users Are Saying

“Great taste and I love it. Mix it up using their suggestion of orange juice. I also like the vanilla powder one which tastes great using their suggestion of cinnamon and graham crackers. Just not so much cinnamon! I just use one teaspoon not the recommended tablespoon.”

“I’ve decided that I don’t like the taste very much. I did lose a few pounds while using this product though so I guess that is a plus”

“It tastes good but gives a weird after taste. I can only drink this when it’s frozen like a shake and extremely cold. Even then there is a weird after taste. After so many shakes I became tired of the taste and now it’s just sitting in my cabinet. Adding fruit helps as well”

Bottom Line

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 $131 a month.

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 this year is one called Burn HD. 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 Burn HD is confident enough in their product to offer a 2-Week Sample, good sign.

We dug deep into the GNC Lean Shakes ingredients to give you the details you need.


Fiber is naturally found in a variety of foods, and is either soluble, meaning it dissolves in water, or insoluble, which means it does not. The body requires both types for optimal health, and both are included in this product.

What is it Supposed to Do?

Fiber helps regulate the digestive tract, and keeps you feeling fuller longer. It can also help remove cholesterol [1] from the body.

Clinical Research

According to a study published in Nutrition Reviews, “The observed changes in energy intake and body weight occur both when the fiber is from naturally high-fiber foods and when it is from a fiber supplement. In view of the fact that mean dietary fiber intake in the United States is currently only 15 g/day (i.e., approximately half the American Heart Association recommendation of 25–30 g/day), efforts to increase dietary fiber in individuals consuming 25 g/day may help to decrease the currently high national prevalence of obesity.”


Protein is a necessary macronutrient. It can be found in meat, dairy, and many fruits and vegetables.

What is it Supposed to Do?

Protein [2] plays a role in many bodily processes, but is the main building block of muscle. Without enough in your diet, you will struggle to lose weight.

Clinical Research

According to a study published in The New England Journal of Medicine, “Several trials showed that low-carbohydrate, high-protein diets resulted in more weight loss over the course of 3 to 6 months than conventional high-carbohydrate, low-fat diets.”

Vitamin A

Vitamin A refers to a group of fat-soluble retinoids and related chemicals. It can be found in carrots and other orange vegetables, as well as meat, fish, and dairy products.

What is it Supposed to Do?

Vitamin A is involved in several bodily functions, including immune function, vision, cellular communication, and reproduction. It supports cell growth and differentiation, and thus is important to the normal formation and maintenance of organs such as the heart, kidneys, and lungs.

Clinical Research

According to a study published in The Journal of Experimental Medicine, “The specific tissue changes which follow the deprivation of fat-soluble vitamin A in albino white rats and in the human concerns epithelial tissues. This effect is the substitution of stratified keratinizing epithelium for normal epithelium in various parts of the respiratory tract, alimentary tract, eyes, and paraocular glands and the genitourinary tract.”

B Vitamins

There are eight total B vitamins, which are necessary to optimal health.

What is it Supposed to Do?

B vitamins play a role in nearly all bodily processes, including energy production, normal nervous system function, metabolism, and more.


Minerals are things like calcium, potassium, and magnesium that the body needs in trace amounts for optimal health and function.

What is it Supposed to Do?

Each mineral plays a key role in overall health, and when minerals become imbalanced, various health problems can result.

GNC Lean Shakes Scientific Abstracts

Oat Bran

The diet containing oat bran cereal significantly decreased serum total cholesterol and serum LDL-cholesterol when compared to corn flakes by 5.4% (p < 0.05) and 8.5% (p < 0.025). The body weights at the end of the study were similar. It was concluded that ready-to-eat oat bran cereal delivered a practical way to infuse soluble fiber into a diet and ultimately reduce serum cholesterol. [1]

Resistant Starch

Results from the study indicate that long-term consumption of raw potato starch elevated crude protein and mucin in pig colons (p < 0.05), as well as reducing total amino acids, tryptamine, ammonia-nitrogen, phenol, branched-chain fatty acid, indole, cresol, and skatole concentrations (p < 0.05) in comparison to the corn starch diet. It was shown that raw potato starch diet up-regulated mucin gene expression MUC12, MUC5AC and MUC4 within pig colons (p < 0.05). In conclusion, it was found that consumption of raw potato starch could enhance the hindgut health by raising mucin secretion and decreasing wild protein fermentation. [2]


When a comparison in values before treatment and after the treatment occurred, substantial decreases were noticed for every parameter except for NEFA and glucose. When these decreased were compared to control and test groups, substantial differences were observed only for haptoglobin (T before versus T after 1545 versus 605 mg/l, P = 0.03; C before versus C after 1635 versus 1400 mg/l, P = NS). There were good correlations between total plasma cholesterol and haptoglobin and between TAG and haptoglobin before, however not following the weight-loss program. It was concluded that giving obese dogs an energy-restricted diet triggered substantial weight-loss and decrease of blood parameters. There was, however, lower serum haptoglobin as well as subclinical inflammatory conditions within the test group, but not control. [3]

Milk Protein

Dairy could very well improve metabolic health in an indirect manner as well as a direct manner. This could happen by helping weight-loss and fat mass via enhanced satiety while aiding skeletal muscle growth and function. This is due to the anabolic effects of dairy protein-derived BCAAs (branch chain amino acids. These BCAAs improve lean body mass, muscle protein synthesis, and skeletal muscle metabolic actions. The avenue which dairy protein is processed and composed has a direct impact on absorption, digestion, branch chain amino acid kinetics and function. Therefore the optimization of dairy protein composition via a combination of individual protein components in milk could deliver a way for increasing benefits of metabolic health. [4]

GNC Lean Shakes are a popular way of bringing about weight loss in your life. Many users would recommend it to their friends and report that it is easy to use, effective, has a good smell, is lightweight, and a good value (more info on their wikipedia page). However, users also report disappointment with product longevity, thereby forcing them to spend more money to purchase a new package of the Lean Shakes. Like most meal replacement bars and shakes, it may leave the consumer hungry. Do not expect it to please your taste buds as a powder mixed with water.

  •  Anita Krulic (Verified User)

    The GNC shake made me so sick that I couldn’t even think about the second shake of the day (this is day one). I had severe gas, bloating, stomach cramps, I became irritable and very hungry. I will not use it again.

  • Samantha Lafontise (Verified User)

    For better results what is best to drink it with fat free milk or water ?? I can’t stand the taste w water ..

    • Montana (Editor)

      Hi Samantha! We see no difference in using milk versus water. Just remember that using fat-free milk will add some calories to the overall shake.

  • Verma

    Do you have to be a certain age to take the Lean Shake 25?

    • Lee Evans

      I lost my weight (45 lbs) and I started at 69 – I’m now 70 – feel great, and blood tests show great results!

        Fantastic Lee. We’re thrilled you’ve achieved amazing results.

  • Can I drink this as regular protein shake?

    Hi. Can I drink this as a regular protein shake after weight lifting or will this still make me lose weight? :/

    • Devon (Editor)

      Well, firstly this shake wouldn’t be what you’d want in a workout shake as it doesn’t contain essential proteins, nor performance enhancing ingredients in its formula. This supplement is claimed to aid in weight loss, not post-workout recovery. However, if you’re really wanting to boost energy and burn fat, you may want to check out Dietspotlight Burn.

    Im trying gnc lean shake 25- I am using to substitute breakfast. will it help me lose weight?

    • Stephen (Editor)

      Hi Deb. It’s fine to replace your breakfast. The program suggests replacing two meals with it. As far as weight loss we have a few concerns with the lack of clinically proven results and dieter’s claims of bad taste. If you’re really want to lose weight, you might want to look at Dietspotlight Burn, which is backed by clinical research.

    I dont buy the powder. I buy tge reafy to drink shakes. I put them in the freezer for about 30 minutes before drinking and it gives it a slushy consistancy. I’ve tried the swiss chocolate, strawberries and cream, and snickerdoodle and love them all! They are a little pricy, but worth it to me. The protien bars are also good.

  • Fatimah Hafer

    Helpful article – I Appreciate the points

  • Sarah

    I have been drinking the lean shakes for almost two years now. I only use one scoop, two is just way too much for my liking. I mix the breakfast scoop with my coffee and the second drink I have for lunch mixed with just water. I eat dinner sensibly (usually under 900 calories). I lost 140 pounds. It can work if you follow the plans. It’s hard work and yes I’m hungry all the time but I’m now a completely different person and I have gnc to thank for that

  • Shawn

    Orange Cream is pretty good, I squeeze an orange into two servings and add water. Tastes good to me, I liked the French Vanilla too.

  •  Chanel Mayfield (Verified User)

    I brought the ready made and have been having one for breakfast. I noticed after the 6 that my stomach was extremely tight. I had to stop because they were causing bloating and acid reflux. They were doing more damage than good. Also they are way too sweet.

  • Dove

    I love the banana flavor lean 25. My question is will using the shakes alone and drinking 2 for whichever meal chosen to replace..do I need to take anything else with this like a fat burner to lose weight or will the shakes work alone?

    • Adrian (Editor)

      Hi Dove! GNC Lean Shakes are meant to replace meals and fill you up faster, not lose weight. If you are looking to shed some pounds, you may want to take a look at Dietspotlight Burn.

  • Javier

    i was wondering if you drink the total lean shake burn prior to working out early morning and then drink the total lean meal replacement after for breakfast would that be good to lose weight? Or could the lean shake burn be also used for meal replacement? That’s what one of the employees said.

    • Adrian (Editor)

      Hi Javier! For detailed product and usage instructions, please refer to the Probioslim official website for more information.

    I have a question. I bought this item in france and i didn’t really understand the instructions, so i drank the milk shake with water instead of milk, so now i’m having a great migraine, pain in my lower abdomen, and feeling sleepy. Please i need help, will this continue?? And whag does this effects means ??. I need a quick answer please!?

    • Devon (Editor)

      Sometimes these symptoms arise as your body tries to accustom itself the whatever formula you’re taking. You’re not alone; other dieters sometimes report headache, cramping, bloating, thirst, irregular bowel movement and nausea. They say these can fade or lessen over time. If they do not however, please seek medical attention.

  • Do we need to workout also ?

    Do you need to workout with this shake ? Or do you just drink it as a meal replacement and the weight comes off

    • Stephen (Editor)

      Your chances of weight loss greatly improve when combined with regular exercise, however GNC Lean Shakes doesn’t require a workout plan.

    Tell us your thoughts about GNC Lean Shake.

    OK I used Lean Shake 25 as a Meal Replacement since August. I recently stopped using it about a month ago as I am at a level I want to be at so I do not need meal replacement any more, I am eating food all day now.

    Yes the Shakes must be blended in a blender to taste good, especially the vanilla. Use 3-6 ice cubes with water or milk in every shake.
    The Chocolate is great.
    The Cookies and Cream needs milk or Vanilla carbmaster milk.
    The Vanilla is not for me but is ok if blended.
    The Bery is good if you add additional frut to it, I did not like it on it’s own.
    Banana is good!! Milk or Water
    Chocolate is the way to go in my opinion, you can blend it super thick with ICE and Milk and eat it like a frosty. Or you can use Water and a few ice cubes for thickening and drink it like a milk shake (without milk).

    Does it taste bad??? Nah… SOme Flavors I didn’t like but I didn’t find the taste Horrible.

    I never got Diarrhea, or chest pains or dizziness. Tjere were days I ate 600 Calories of food and Drank 3 shakes a day.

    EXPENSIVE?? YES – do not buy from GNC unless your a gold member or they are having a sale.
    I ended up waiting for black friday where it was $21.00 a container and bought 20 of them.
    WHen I needed refills I also bought from ebay, sellers (nutrition stores who buy and resell from GNC) sell for black friday prices all the time 21/23 shipped a container. This is also a good way to get different flavors.

    Does it work?? WELL yes and NO.
    If you have/eat a Diet regimen that is 500 Calories UNDER your Maintenance weight and use this 1 to 3 times a day you will loose weight and pretty quickly. I did 1300 calories a day for the first 3 months drinking 2-3 shakes a day. The rest of my diet was Chicken, (protein) Beef, ect… Broccoli, and Greens. Very little Fat and Carbs (one sandwich of chicken a day where the bread, rye, was my carbs) . Of Course your diet will differ. Yes you need to exercise too. All I did was walk for 1 hour a day (EVERYDAY) at 2.5-3.5 MPH as I started loosing weight I used a Treadmill and started to use the incline for more calories to burn. During the late summer and Early Fall I was also taking night walks where I would push the kids in a stroller (good resistance) for 1-2 miles and go at a pace that I did not break a sweat at all, just a calm relaxing walk. Yes that 1-2 miles extra a few nights a week helped too. When IT got cold I stuck with just Walking on a treadmill. YES, again I did it every day and I still do 8 months later.

    Do you weight train…?
    I do now, But not when I started. THe Lean Shake and Walking and 1300 Calories was all I did from June – September. I went from 212 to 178. Then I had a whole different Regine where I was still doing 1 maybe 2 lean shakes a day but a whole new routine for weights and such.

    When I stopped using lean shake I just cracked the high 140’s in my weight.

    I still have a shake Now and then (I keep one chocolate container in the closet and but again when I run out) But I only have one on days where I feel like I had too much food the day before and I want something to keep me full and be low calories (200 or less) but be filling.

  •  I lost 27lbs in 3 months !
    KatieCT (Verified User)

    I have been drinking the Total Lean 25 Shakes (the pre-bottled, premixed that come in a 4-pack) since Jan. 4, 2016. It is now March 5, 2016 and I have lost 27 lbs. in 3 months. I am a female, age 50, 5 Ft 7. I need to lose another 30-ish lbs. I started at size 18 and now in a size 14 (tightly). I hope to get down to a size 10. I am giving myself until September 2016. I drink one at lunch each day with nothing else. I drinks lots of water throughout the day at the office. I eat a low carb diet, usually a cheese omelet in the morning and for dinner either chicken, fish or beef with vegetables like broccoli, cauliflower or salad greens (I stay away from sugar, sweets, flour, pasta, bread, fruit, etc.). I have not exercised whatsoever, but will begin to do so as I start my 4th month (probably do 40 mins. on treadmill daily to start, then add in strength training). Like some have mentioned, I had 2 incidents with diarrhea upon my first few days of drinking Total Lean 25. I have not had any problems since. Sometimes when I drink the shake too quickly, I will feel bloated afterwards, but for the most part all is good. It keeps me full until about 6:00 p.m. at night. I started out drinking the Strawberry, Banana and Pumpkin Spice. I now drink the Swiss Chocolate. I like the pre-bottled shakes, because I can grab it in the morning as I am always in a rush to get to work and pack it in my handbag. Lunch time rolls around, I just shake up the bottle and put a straw in it and I am good to go. No mixing, no powder, no fuss. 170 calories, 25 grams of protein, can’t beat that.

      I purchased the total lean protein podwer…cookies and cream….and planning on tasting french vanilla…but I been doing great ..I have one for breakfast on the go and 1 during lunch time….it makes it easier for me to get my protein and still not be hunger….and for dinner I have a my dinner…I a salad plate of whatever I’m going to eat…nothing …different of my dinner had to change…but my portion size cause I change my plate size…which don’t give me room to put much food on my plate….so I’ve been on it for 2 weeks and I lost 5 lbs…..I drink plenty of water.throughout the day..and after shake..because of it thickness…for digesting…but I’m going to try the vegan vegetable and the French vanilla together with 1 scoop each….to get my vegetable in take when I’m not eating enough veggies…I would probably be on this product for long term….it’s easy…and satisfying…for on the go.

      Some dieters say these effects fade as your body acclimates to the formula, however this is an indeterminate amount of time. If these issues persist we recommend you stop them and consult your doctor, Fabi.

    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)

          After a full week of taking it you are still experiencing side effects you must consult with your doctor to ensure this formula is safe for you. The side effects are of major concern to us.

  • Can you mix lean shake only with water or milk?

    Can you mix lean shake only with water? Can you mix it with skim or 1 percent milk?

    • Harleygurl

      I’ve mixed mine with water and 1% milk. Using 1% milk and a little ice then mixing in my Nutribullet! Great consistency! I love the French Vanilla, Choc is ok leaves an after taste!

      You can also use coconut milk since coconut oil is so expensive.

      I just bout my very first one today since it was recommended by my boyfriend who works at GNC and I loved it. I bought the bottle just to try it and bought two small packages for tomorrow morning. I have not tried it with water yet but the flavor that I got was Chocolate and it was great!

    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.

    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.

  • Best food to eat while taking this

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

    • Cameron (Editor)

      Keeping a low calorie and low carb diet is best for any diet shake or supplement. Avoid foods high in fat. Program actually wants you to use the shake in place of food, Bill.

  •  Love the product because it works

    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!

    I love the lean shake, im currently a breastfeeding mother of a 2 month old and I been looking up if its safe to drink well breastfeeding. I workout 4-6 days a week. so my question is is it safe?

    • Cameron (Editor)

      Some meal replacement programs are not safe for nursing mothers. However we haven’t come across nursing dieters experiencing issues. Above all, ask your doctor, Heather.

  •  Don't like the taste

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

  • how long the normal person stays on this product

    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?

    • Maxine

      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.
