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 Prevention magazine, 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.

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, according to WebMD. 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
  • Diarrhea
  • Constipation
  • Nausea

What about breastfeeding moms? Can they use GNC Lean Shakes? According to, 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.”

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.

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 published by the International Journal of Obesity and Related Metabolic Disorders) saying an average weight loss of one to three pounds per week.

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”

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 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 TS. 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 see wonderful results.

Also, the company behind Burn TS is confident enough in their product to offer a 2-Week Sample, a good sign.

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.

Choosing the right weight-loss system can be confusing and often times frustrating. Let us help. Let us know a little more about you and your goals.
