The results of my research into Right Size were somewhat surprising. We took a deep look at the ingredients, side effects, clinical research, and customer search to see what the deal was. Then, to see what people were really saying, we went to read through hundreds of reviews. Finally, we condensed it all to give you all the facts you need.

Right Size Readers: Click here to find out why we're giving away samples of our product, Dietspotlight Burn.

What is Right Size?

Firstly, Right Size meal replacement shakes are supposed to help you lose weight by using them in place of one or two meals per day for six weeks. Ingredients include Appemine, which is made up of Green Tea Extract, Cinnamon Twig and Galangal. It is available in a variety of flavors including chocolate, vanilla, cappuccino, and berry blend.

Right Size shakes are made by a company of the same name. The official website opened in 2006, but the product could have been available longer than that. It looks like you have to send an email to get a link to preorder.

Side Effects – “Racing Heart”

The first thing that caught our attention is that some users report Right Size side effects. “The main ingredient may be the culprit, because of the green tea being a stimulant. It may just be a little too much for some customers,” said our Research Editor.

”When I used these, I felt jittery,” claimed a dieter.

”When I drank these shakes, I felt full, but my heart was really racy,” a reviewer explained.

Not everyone experienced side effects, however.

“I loved all the flavors I tried, and I didn’t get any side effects,” said one customer.

As a customer put it, “I experienced no side effects while using these meal replacement shakes.”

Right Size Meal Replacements – “Not Enough Nutrition”

Some in the medical community have mixed feelings about using meal replacements, since they can dramatically cut your calorie intake. This could mean your metabolism actually slows down, making it harder to lose weight in the long run.

”I always felt hungry when using these shakes,” said one user.

”Even replacing one meal a day with these, I still ate less than 1200 calories a day,” a dieter shared.

Some people loved the program.

“I lost 15 pounds over the course of the six weeks I followed this program,” one review shared.

“I got excellent results on this program,” said a customer.

Over the years, we’ve found it takes one thing, like side effects, to make customers look for other products. They want to lose weight, but they want to feel good while doing it and if Right Size leaves them feeling off, that’s not a good thing.

The Science – “More is Needed”

The main ingredient, Appemine, needs further studies to determine how well it works as a weight-loss supplement. It does contain green tea and cinnamon, which have been shown to help, but nothing says this particular brand is superior.

The Bottom Line – Does Right Size Work?

Should you race out for a bottle of Right Size? That’s a difficult question to answer. There are dieters who saw results and those who felt hungry all the time. What we do know is that this product is not unique and the ingredient list has not been directly, clinically tested, which is why we have reservations.

If you’re ready to lose weight, we think you may want to try using a dietary supplement made with clinically tested ingredients known to help support weight-loss. And, for an extra boost, make lifestyle changes to include exercise and a healthier diet.

Among the best products we’ve seen this year is one called Dietspotlight Burn. It’s formulated with a blend of four scientifically tested ingredients, known for their ability to help boost your metabolism and keep you from getting too hungry between meals. We couldn’t find anything negative about the product itself, or mentions of harmful side effects, so users seem to be happy with their results. Plus, only sensible changes have to be made to diet so you’re not hungry all the time.

Plus, right now, customers can get in on a Special Trial, available directly from the manufacturer. This is something we like to see.

What You Should Know

Right Size is a company that produces meal replacement shakes and a number of other weight loss products. Right Size says that you will lose weight if you follow their six week weight loss plan, which involves replacing one to two meals a day with their meal replacement shakes. The meal replacement shakes by Right Size all contain a product known as Appemine. Appemine is made up of green tea extract, cinnamon twig and galangal.


The major active ingredient in the meal replacement shakes by Right Size is Appemine. Appemine is made up of Green Tea Extract, Cinnamon Twig and Galangal.

Product Features

Right Size say that Appemine, which is in all of their meal replacement shakes, is a biogenic amine that affects the adrenal receptors in the body and thus helps procure weight loss. Green tea extract, which is in Appemine, is a common ingredient in weight loss products on the market today. Galangal is a plant in the ginger family and is a common ingredient in Thai and Southeast Asian cuisine. It is said to have stimulant and weight loss properties. Cinnamon is also said to have weight loss properties. The meal replacement shakes are available in a variety of flavours, namely chocolate, cappuccino, and vanilla. There is also a Berry Blend flavour that consists of a mix of raspberry, strawberry and blueberry flavours. The shakes can be ordered directly from the official website and cost $54.95. Right Size also manufacture a multivitamin with Appemine, which can be ordered directly from their website and costs $29.95 for a month's supply.


  • Right size has a detailed, official and informative website.
  • The meal replacement shakes can be ordered directly from the official website.
  • There is a list of ingredients available for Appemine, the major active component in the meal replacement shakes by Right Size.


  • There have been no controlled, standardized tests carried out on Appemine.
  • There is no clinical evidence that we could find proving the meal replacement shakes by Right Size do actually stimulate weight loss.
  • The medical community is currently very sceptical of meal replacement diet programs in general, and there is concern that skipping meals leads to poor nutrition and an unstable metabolism.
  • May cause your heart to race. (See reader comments.)
  • Not all users may enjoy the taste of these meal replacement shakes, or find that they feel adequately full after having one.


Some diet experts are now expressing concern that some people are using meal replacement shakes as a permanent solution to weight loss. They say that any of the meal replacement shakes on the market should only ever be used in the short term, and that the ideal solution to weight loss is a permanent change in eating habits. In Right Size's favor, they do say on their web site that their meal replacement shakes form part of a six-week plan. Still, in the long run users will probably still need to to change their overall eating habits following a course of Right Size in order to keep off any lost weight.

   stomach and heart

I have been using Right Size Shakes as a breakfast meal replacement about 5 days a week. Sometimes I use it as a treat rather than rummaging for a popsicle when I want something cool and tasty. I also add frozen fruit and mix it with almond milk and water. When combined with a regular walking-stretching routine I find I keep weight down. I also have been buying it at CVS not online. The price at CVS runs about $35 a 20 serving canister. I also found there are single serving packets available which are great to carry along for out of town or lunch at the desk . I work 40+ hours a week and am 60 years old. I am however currently considering Arbonne shakes as they contain 9g of sugar and 20g of protein. Draw back is they are using stevia where they used to use loquat for sweetner…. stomach and heart can only take so much stevia…. it’s my own body allergy build up.


This product caused me to be very constipated so I stopped using it. Not worth it,.

  Shake less effective
Liz (Verified User)

Just got off the phone with world’s worst service rep. I had weird pains in my sides, sharp pains in head and found the shake less effective than Medifast for app. suppress. The rep was beyond aggressive and the “free” trial is expensive. Run away!

Linda (Verified User)

no refunds is exactly right. rightsize is the wrong fit for any hard working person who wants to try a new product on a trial basis.don’t believe the 29.95 trial offer.
