Description
As far as meal replacement shakes go, GNC lean shake seems to at the top of the list. This whey protein-based shake is designed to aid in weight loss as well as promote muscle building.
But, one looming problem; According to GNC Holding Inc., the lean shake is scientifically designed to enhance a leaner body. However, I have not found any scientific research on the formula used on their website.
Don’t get me wrong; research does exist on the various ingredients used like whey protein and fiber. But, the implication that the product’s formula is scientifically proven, while it’s not, it kind of a problem.
However, despite this red flag, lean shake has been widely accepted by many people. The meal replacement shake has received mostly positive results from its customers, most implying that it works.
1. What Is It: A Closer Look at GNC Lean Shake
GNC lean shake contains both soluble and is high in protein to provide satiety.
GNC lean shake is a protein powder designed to limit calorie intake and promote weight loss. This shake is formulated with a blend of vitamins, minerals, protein, and fiber that promotes satiety, improves digestion, and regularity.
Q. Does GNC Lean Shake qualify as a meal replacement shake?
According to WebMD, a meal replacement shake should offer:
- 200 to 230 calories per serving
- <5 grams of fat
- 3-5 grams of fiber
- 10-15 g of protein
- And at least 30% of the RDA of vitamins and minerals
Although GNC lean shake contains 180 calories per serving– which is low, it compensates in the other features. Not only does GNC have less fat, but it provides more protein than most shakes. Additionally, the fiber content is within the recommended dosage. So, yes lean shake is a meal replacement powder.
2. History of the Brand
General Nutrition Centers Logo
GNC (General Nutrition Centers), founded in 1935 is behind lean shake. The American-based company has its headquarters in Pittsburgh, Pennsylvania, and it develops and sells vitamins, sports nutrition, beauty, herbs and energy products.
- Where are the supplements manufactured?
GNC lean shake and other supplements are manufactured in a privately-owned company– Nutra Manufacturing, Inc.located in Greenville, S.C. Unlike most supplement companies, GNC owns and manufactures its supplements, probably the reason why the shake is cheaper than other replacement shakes in the market.
3. Ingredients Used
-
Whey Protein Blend
GNC contains both whey isolate and concentrate.
GNC lean shake is rich in both concentrate and isolates protein. Both of these Whey types have different concentration. For instance, Whey concentrate contains 70-80% protein, lactose, and fat. Isolate, on the other hand, is 90% protein, but is less in lactose, and also lacks most of the nutrients found in concentrate.
Whey protein is easily absorbed and utilized compared to other protein forms [2]. Additionally, it can boost your energy expenditure to around 80-100 calories a day. Furthermore, it promotes muscle gain, increases insulin and plasma amino acids that stimulate muscle growth [1].
One study discovered that consuming 25% of protein can reduce your cravings bu 60% [3].
Lean shake contains 25 g of protein which can mean that it is effective in reducing appetite and curbs cravings.
-
Vitamin blend
One glaring problem with the low-calorie diets is the vitamin and mineral deficiencies. GNC lean shake contains a blend of vitamins and minerals that maintain the normal body levels. Some of the nutrients include:
- Calcium improves bone health and strength
- Iron promotes blood function and circulation
- Vitamin A promotes healthy eyes and supports bone health
- Riboflavin enhances energy production and increases blood flow
- Vitamin C repairs body tissues and promotes the formation of collagen
- Thiamin supports nerve brain and muscle health
- Vitamin E acts as an antioxidant and moisturizer for the skin
- Niacin lowers triglycerides and increases HDL cholesterol
- Zinc builds the immune system
- Vitamin B12 that boosts immunity and increases energy
-
Fiber
Dietary fiber offers significant benefits from lowering cholesterol to weight loss. However, according to Mayo Clinic, an adult needs around 28 grams per day. GNC lean shake contains 13 grams dietary and soluble fiber– which most might argue that is small to produce any significant results. However, as a meal replacement shake, it contains the right amount needed.
GNC Lean shake also contains milk protein concentrate, which in combination with whey can increase protein synthesis.
