They do mention that not all results are the same, and that everyone has their own needs when looking to lose weight. Inside are also several ingredients which are often added to weight loss supplements. Is there any real benefit to using this meal replacement? What kinds of results are possible, if any? In this Right Size Smoothies review you’ll learn everything needed to make an educated decision.

Right Size Smoothies Ingredients and Side Effects

Here are the ingredients to their Skinni Vanilli flavor: 

Soy Protein Isolate Resistant Maltodextrin Crystalline Fructose Canola Oil Corn Syrup Solids
Maltodextrin Natural and Artificial Flavors Silicon Dioxide Carboxymethycellulose Gum Xanthan Gum
Salt Sodium Caseinate Green Tea Extract Dipotassium Phosphate Acesulfame Potassium
Soy Lecithin Mono and Diglycerides Ginger Root Extract Sucralose Cinnamon Bark Extract
Dicalcium Phosphate Dimagnesium Phosphate Ascorbic Acid Vitamin E Acetate Niacinamide
Zinc Citrate D-Calcium Pantothenate Vitamin A Palminate Pyridoxine Hydrochloride Manganese Sulfate
Rioflavin Thiamin Mononitrate Copper Gluconate Folic Acid Biotin
Chromium Picolinate Potassium Iodide Phytonadione Sodium Molybdate Sodium Selenite
Cholecalciferol Cyanocobalamin

Soy Protein Isolate: Extracted soybean protein that’s 90% protein by weight.  It contains potentially elevated levels of phytates, goitrogens, and estrogen like compounds.

A study by the National Center for Toxicological Research concludes that soy:

“soy products may cause harm in the human population via their estrogenic and goitrogenic activities” 

Goitrogens can cause damage to the thyroid, which can harm overall health and cause weight gain.

Estrogen can also cause unwanted side effects in both men and women. This is because estrogen is a hormone which needs to be regulated in order to prevent problems to overall health.

The American Journal of Clinical Nutrition also studied soy and the concluded that:

“soy promotes less energy expenditure and a lower rate of fat oxidation than dairy-based proteins” 

So this means it’s not as good for weight loss than something like whey protein.

Crystalline Fructose: This fruit sugar is considered one of the worst choices for sweeteners according to many studies.

One clinical study performed by the University of California confirmed that fructose:

“alters hundreds of brain genes, which can lead to a wide range of diseases” 

This includes diabetes, Alzheimer’s, ADHD, and cardiovascular disease to name a few.

It’s also been shown to not be appetite reducing, so you can eat significant amounts of it and not feel satiated. This can cause significant weight gain and metabolism disorders.

Artificial Flavors: A laboratory made ingredient used to mimic the natural taste of an ingredient. It can be extracted from many things, including common allergens.

Carboxymethyl Cellulose: A thickener added to processed foods. A study by the International Weekly Journal of Science showed that this ingredient caused:

“low-grade inflammation can promote adiposity and its associated metabolic effects” 

“might be contributing to an increased… obesity/metabolic syndrome and other chronic inflammatory diseases” 

This can potentially cause serious issues to overall health. It can also make weight loss much harder.

Sucralose: Artificial sweetener which is not broken down by the body. After this ingredient was shown in studies to cause leukemia, the Center for Science in the Public Interest downgraded its safety to “Caution”.

A study by the Washington University School of Medicine showed that sucralose:

“Affect Glycemic and Hormonal Responses” 

This can have damaging effects to overall health, and it can increase the risk for obesity.

Mono and Diglycerides: Used to help fats and liquids combine better in a formula. This ingredient is considered an emulsifier, as such; it contains trans fats but does not need to be listed as a trans-fat according to the FDA.

Tran’s fats are known to cause many issues which Live Strong.com mentions are:

“heart disease, stroke and diabetes” 

“promote inflammation and obesity” 

It’s advised to not take any trans fats by many health organizations. It’s considered an extremely harmful ingredient that has no benefit. It’s only added to processed foods in order to impart a stabilizing effect. There’s no nutritional value.

Xanthan Gum: Cheap thickener included in many processed foods. It’s also added to help regulate blood sugar levels.

Possible side effects may include:

  • Flatulence and bloating.
  • Nausea, increased bathroom usage, and upset stomach.
Right Size Smoothies Quality Of Ingredients 

right-size-smoothiesThere’s cheap sweeteners added to this including crystalline fructose, sucralose, and corn syrup solids.

Also, there’s only soy protein which is GMO. This ingredient has been shown to potentially cause many issues, and it’s considered a cheap and potentially dangerous ingredient.

Though this shake has just 100 calories and 6 grams of fiber, overall the nutritional content is limited.

Many ingredients added to this have been shown to potentially cause damage to overall health, as well as increase the risk for obesity.

The Price and Quality of Right Size Smoothies 

The official website does not list any prices. It’s unknown if the market price on online retail sites is accurate with what’s priced.

One 20 serving jug sells for $29.99 on Amazon.com. Though it’s impossible to determine whether or not these batches are still fresh. As new management has taken over, it’s unknown if they will continue to use old batches from the previous owners.

For the kinds of ingredients added and due to the lack of a money back guarantee, there’s a lot of potential risk involved. This shake has cheap binders, GMO soy, and artificial ingredients added. There’s also the possibility for weight gain due to the fructose which comes in at 6 grams per serving. 

Business of Right Size Smoothies 

The official website says that the company:

“Right Size is under new management and ownership” 

There’s no information about the company on their official website. No email, phone number, address, or mention of a money back guarantee.

They do mention they still sell their vanilla and chocolate shake, but they fail to provide any useful information.

It’s unknown if they are in any way affiliated with the same company listed on the Better Business Bureau website. They currently have a D- rating for customer satisfaction, and there are several negative reviews about the company’s practices.

This might be the reason why there are new manufacturers who have taken over.

Though without a money back guarantee or company information, it’s unknown if it would be safe to purchase this brand now. Customers have had the following to say about the old practices:

“would not allow me to speak to a manager or supervisor and disconnected me” 

“took out a nice chunk of change for a product that did not work” 

“I just want my money back” 

Many have complained about the lack of customer support. It’s unknown why the new owners haven’t listed any contact information. You’re unable to call them to ask about a money back return, or to gain any support on how to use their shakes.

Because of the lacking information, it’s impossible to determine how customers will be able to safely use this brand.

Customer Opinions of Right Size Smoothies 

Many negative reviews are available online. Here’s what some customers have had to say:

“Doesn’t work at all” 

“Didn’t suppress my appetite, made me bloated and gassy” 

“Did not help me at all” 

“waste of money” 

Some customers have problems with side effects, and many failed to see any appetite suppression or weight loss benefits.

Consumers were also disappointed to find out they couldn’t make a return. Many were lured in by a free trial, though because of the lack of communication, they couldn’t cancel future shipments.

It’s unknown how the new management deals with new customers.
