Pea Protein Isolate: A 90% protein by weight extract made from peas. It’s low in the amino acids methionine and cysteine.
Pea protein is also known to have purines, which can lead to gout. This is a condition that is caused by too much uric acid. People susceptible to this are often advised to avoid foods like pea protein. Live Strong.com adds:
- “your kidneys may not be able to keep up, leading to the development of some medical conditions”
Pea protein is often mixed with other sources of protein to make up for the lack of amino acids.
Artificial Flavors: Man made ingredient used to provide a certain flavor. Because it’s not natural, it can be made from many different chemicals. It’s unknown what kind of an effect this may have on the body.
Carrageenan: A gelling and thickening agent made from seaweed. Because of its potential for causing cancer, the University of Iowa states:
- “widespread use of carrageenan in the Western diet should be reconsidered”
Their analysis of this ingredient showed that it wasn’t worth using. There are far too many potential dangers according to their review.
Xanthan Gum: Commonly used thickener found in many processed foods, it’s a combination of fermented sugar and bacteria.
Side effects are possible and include:
- Gas.
- Bloating.
In high amounts it can lead to laxative effects.
Guar Gum: Thickener and binder used to help liquids and dry ingredients blend better. It’s often used as a laxative ,and as an additive to weight loss formulas.
Though it’s advised to drink at least 8 ounces of water with it to prevent choking. Web MD confirms this by saying:
- “water is important because it reduces the changes of choking or developing a blockage in the intestine”
It can potentially lead to side effects that include:
- Loose stools and diarrhea.
- Blockage of the esophagus and intestines.
- Increased gas.
Green Coffee Bean Extract: Unroasted coffee beans that are used to help control blood sugar and metabolism. Due to its natural caffeine it can potentially lead to side effects:
- Insomnia.
- Rapid heart rate.
- Irregular breathing.
- Anxiety.
- Vomiting.
- Ringing in the ears.
It’s unknown how much caffeine is found in this shake. It’s important to know this amount since adding any other stimulants can increase the risk for side effects.
Also, there’s a potential for insomnia if you take it too late in the day.
Hoodia Gordonii: A shrub made used to help suppress appetite. Examine.com mentions:
- “failures of Hoodia to suppress appetite it may also be midly toxic”
Therefore, it has not been proven useful, and it’s potentially harmful.
Sucralose: Artificial sweetener that provides no calories. It can be up to 1,000 times sweeter than sucrose.
Studies have been performed on this ingredient that showed it’s not healthy. According to a clinical study by Science Direct, sucralose:
- “induced DNA damage in gastrointestinal organs”
The Journal of Toxicology and Environmental Health also ran a study on mice. It showed:
- “numerous adverse affects”
- “reduction in beneficial fecal microflora, increased fecal pH… enhanced expression levels of P-gp.
So in reducing gut bacteria it can potentially cause issues with the immune system. Increased P-gp is usually only possible when a contaminant enters the body.
It allows for foreign objects to be taken out of the body. It can also cause drug resistance, which can be a problem for those on medications.
EDITOR’S TIP: Combine this supplement with a proven meal replacement such as 18Shake for better results.
Lean1 Quality Of Ingredients
One unique thing about the shake is the use of ingredients like green coffee bean extract. This is often added to weight loss supplements, and usually brands list the total caffeine content.
There’s unknown amounts of caffeine added. This can be potentially dangerous as you won’t know if you’re getting an excess amount.
There is a high amount of protein at 20 grams, though some of it comes from pea protein, which can potentially cause gout. Also, there’s cheap protein in the form of milk protein isolate and sodium caseinate. These are inexpensive to produce, and all together there’s no notice of the total amino acid content.
Knowing the amino acid amount is essential for determining if your protein is high quality.
There are also 17 different powdered fruits and vegetables. Though the product has added vitamins and minerals, which means most of if not all of the nutritional value is lost from these fruits and vegetables.
The Price and Quality of Lean1
A 15-serving amount of Lean1 sells for $39.97.
The company also offers a reduced price for auto renewal subscriptions, though this is a way to lock people into month-to-month contracts.
A full one-month serving will cost $79.94. This means it’s in the higher end of pricing.
The kinds of ingredients used aren’t the best. You get ingredients that can be toxic like Hoodia Gordonii, and there’s also cheap protein added. The addition of green coffee bean extract is also not the best ingredient due to potential side effects.
There’s a high amount of vitamins and minerals found, but overall the lack of quality makes this an overpriced meal replacement.

Conclusion – Does Lean1 Work?
Though you might get the urge to sample Lean1, there are a few things to consider. No returns are offered on opened products, many customers couldn’t drink it due to the taste, and there’s potentially toxic ingredients added. Lean1 seemed impressive due to its many claims of it being a fat burning meal replacement, and due to it containing a solid 20 grams of protein. However, judging from the ingredients and mixed customer experience, it’s not the best meal replacement out.
When looking for a meal replacement ideally you want to make sure it’s all natural, free of stimulants, full of only high quality protein, and you should know exactly how much amino acids are contained.
Out of all the possible meal replacement shakes available in 2022, only 18Shake met all the criteria for a standout product.
It’s made with 2 easy to digest forms of protein in whey isolate and whey concentrate. There’s also no binders, fillers, artificial ingredients, or unnecessary stimulants. It works due to its quality fiber and protein that help suppress appetite while helping to promote lean muscle growth.
This is likely why the makers offer a solid money back guarantee on 18Shake; it’s now ranked as the best meal replacement on the market due to its all around great ingredients made for real weight loss.
What Is Lean1?
Lean1 Fat Burning Meal Replacement is a weight loss shake produced by a US-based company named Nutrition 53.
One tub of Lean1 contains 15 servings and costs $39.97, which works out at $2.66 per replaced meal.
This product seems to only be available via the official Lean1 website, Amazon, GNC and Walmart.
To date there is very little trading history information on the manufacturers Nutrition 53, the brand are not on the Better Business Bureau Database and we couldn’t find them on any other customer review websites.
Lean1 Shake finds itself placed at the core of Nutrition 53’s weight management range; it is marketed as a meal replacement shake that contains fat burning ingredients and is nutrient-dense. Interestingly Nutrition 53 make absolutely no clear directions of usage for Lean1 – the packaging simply states “mix 2-3 scoops into water and consume”, users are not told how many meals they need to replace, nor are they told what to eat in-between servings.
Consumers are promised a multitude of effects such as suppressed hunger levels, the increased ability to burn body fat and boosted energy levels.
And just in case you are not a vanilla person, you still do not have to worry. Another great flavour in Nutrition 53 Lean1 Protein Powder is strawberry Banana. Now, who can say no to the fruity flavours in your meal supplements? It will be like eating fruits for meals and losing weight almost effortlessly. For some customers, this flavour combo was too much to handle though. They complained of the flavours following each other which they didn’t seem to like very much. However, other customers liked this flavour as much as they liked the lean 1 chocolate flavour.

Sunflower oil has many benefits. It is rich in vitamin K and vitamin E along with other nutrients. It promotes heart health and also helps in lowering cholesterol. Sunflower oils have been traditionally healthy foods and the usage of this in a meal supplement makes the meal supplement much more effective.

- Alkalized Cocoa Powder
Now, this is one lesser talked component that is great for weight loss and gaining leaner muscles. Before we move ahead, let us tell you what the alkalized cocoa powder is. Cocoa powder is made by two processes, one of which is Dutch. The Dutch process of treating the ingredients includes washing them with a solution of potassium carbonate in order to bring the cocoa’s acidity level to 7. Nutrition 53 Lean one promises the presence of alkalized cocoa powder which enhances its antioxidant properties. This is why this is one gem of an ingredient in this product.
Lean1 is a meal replacement protein powder that promises fast fat burning. The formula uses a proportionate amount of protein, fiber, carbohydrates, vitamins, and minerals to speed up weight loss, reduce hunger cravings, and activate muscle-building in the body.

Branched-chain amino acids (BCAA) found in whey protein are responsible for tissue maintenance and the prevention of catabolic actions while exercising.
