Slender Wonder Review - Does This Weight-Loss Program Work?

By Summer Banks Aug 10, 2017

I paused before I hit the “publish” button on this one, because my conclusion was a bit of a shocker. We at DietSpotlight wrote a comprehensive review on Slender Wonder, examining the side effects, ingredients, clinical studies and level of customer care. We additionally scrutinized all sorts of user comments found online. Lastly, we summed up all of the facts and details to give you the bottom line.

What is Slender Wonder?

First of all, Slender Wonder is a weight-loss program. The ingredients or components include supplements, snack bars, laxatives, injections and low-calorie meals. This method involves doctor visits, reducing your daily calorie intake, internal cleansing, and giving yourself shots. It has five different phases. These are as follows, stimulation phase, detox, weight-loss, stabilization, and maintenance. You are weighed and measured once or twice each month. You are also expected to follow a meal plan that is designed specifically for you.

Slender Wonder has been around since at least 2014. This medical weight-loss program was started in South Africa. The official website provides a “find a doctor” tool. There are also some before and after photos posted on the website, but read on…

Slender Wonder Injections – “Concerned?”

The first concern were Slender Wonder side effects occurring from the injections. “With this weight-loss program, you are expected to administer shots at home on a regular basis,” said our Research Editor. “There have been reports of adverse reactions from this process.”

One person stated, “I understand the use of shots, but they hurt too much for me to continue.”

But, another dieter commented, “It’s a little odd to administer injections. However, it’s not really that bad.”

Another posted, “The injections are painful, but I am determined to get this weight off.”

Limited Locations – “Another Issue”

Another issue is the limited doctor locations. In fact, one person commented, “This is just in South Africa from what I can tell. I reside in a different country. So I guess Slender Wonder is not the best choice for me. I don’t see any doctor locations in my area.”

However, a different person stated, “Tried Slender Wonder for a few months. It’s challenging, but I did lose some weight. The downside is all of the supplements and injections.”

“This weight-loss program is really involved. Therefore you must be willing to commit. Be ready for some Slender Wonder side effects too. I experienced nausea and serious hunger on a regular basis,” posted another.

According to our research, if there’s a certain facet of a diet program that is quite difficult or problematic (painful injections, limited locations, high cost) the likelihood of long-term success is minimal. This means if Slender Wonder shots do bother a lot of dieters, this could be a serious dilemma.

The Science – “Is Any Presented?”

Unfortunately we did not pinpoint any documented studies on the official website to support Slender Wonder. This is too bad, because we at DietSpotlight prefer to see some published science that backs up the weight-loss program or product and its marketing claims.

The Bottom Line – Does Slender Wonder Work?

So, should you invest in the Slender Wonder weight-loss program? Well, to begin, we like that you receive actual doctor assistance with this diet. We also appreciate that a special eating plan is created to help you lose weight. However, we have some reservations about this method because it’s not backed by any documented research. Also, we’re concerned about the painful shots you have to administer regularly. Not to mention the limited clinic locations.

If you really want to shed some pounds, then we advise you to choose a diet program or supplement that is supported by solid science, does not require any painful injections, and is easy for anyone to use anywhere.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This supplement contains a unique blend of four ingredients. Some of which have been clinically tested and are shown to help ignite fat loss and elevate metabolism. So far we have not spotted any discouraging user reviews, and comments around the web express people are seeing wonderful results.

The makers of Dietspotlight Burn are so positive about their product they’re offering a Special Trial Offer, which is uncommon.

What You Should Know about Slender Wonder

Slender Wonder is a weight loss system that aims to control Leptin to increase weight loss. There is a long list of supplements and products sold as part of the system, including Protein Plus Shake, Herbaboost (Fat Burn), Pyruvite, Omega 3 and 6 (Fat Flush), Magnetine, Easy Hoodia Plus (Zero Hunger), CLA (Fat Block), Prime Lipoic Acid, Easy Cleanze, K-L Cleanze and Lipo Lite Oral Drops. Most of the website is in another language because the program is only available in South Africa.

List of Slender Wonder Ingredients

Product Features

There are three stages to the Slender Wonder program - a low glycemic diet, supplements and injections. We assume the injections are leptin, but that is not detailed on the official website. The supplement list offers some insight into the Slender Wonder program. Most of the supplements contain diuretics and laxatives, including the fat burners. There are no stimulants in any of the supplements so metabolism will not increase without exercise. With two designated cleansing supplements and cleansing ingredients like bladderwrack and liquorice root in the fat burner, weight loss is likely associated with water loss and increased bowel movements.

Losing weight with laxatives and diuretics is not a safe choice for any dieter. These ingredients should only be used to fight occasional constipation. If used for a longer period, the bowels may grow accustomed to the laxatives and fail to work properly without supplementation. Diuretics can also lead to lower than normal potassium levels. Low potassium can lead to death.

The Slender Wonder program is not available in the United States, so dieters must live in South Africa near a clinic to utilize the weight loss treatments. With injections, the cost of the program is likely to be higher than the average fat burner.

Advantages of Slender Wonder

  • May increase weight loss due to the low glycemic diet.
  • Ingredients are listed for all supplements on the official Slender Wonder website.

Disadvantages of Slender Wonder

  • Supplements contain laxatives and diuretics.
  • Only available to locals in South Africa.
  • Injections likely increase the cost of the program.
  • The dieter must purchase a long list of supplements.


When it comes to losing weight, there may be a time when occasional constipation forces the dieter onto a plateau. During these times, a colon cleanser is ideal for relieving constipation, but these supplements are not created for weight loss. Proven fat burners are a more effective choice for weight loss compared to the Slender Wonder program.

I lost 30kg but stopped and in a year’s time picked up all I am heart broken please help


Hi Annelize,
You likely didnt stabilize or follow the maintenance plan that is included in the diet manual. Without doing so, and returning to “normal” eating habits, the weight will come back. Slender wonder isnt a cure, it is a program assist with lifestyle changes which are required to maintain a healthy weight.
I would suggest returning to the program, lose the weight and see the program through to the end (including the year of maintenance).
Good luck 🙂

Very true. If you eat like you ate before, you will look like you looked before…


I am.on heavy psych meds that have caused great weight gain. I am also diabetic. Can I use slender wonder?

Victoria (Editor)

Hi! Because of possible interactions with medications, please make sure to consult with your physician before taking this product.


I tried the diet and the injections and it realy was not that painful. My only concern was the low calorie diet made daily gym sessions difficult. The cookies and cream bars are amazing. 🙂

I have done the program – It is fabulous, I started at 92 kgs and now weigh 77 kgs. and have kept all the weight off for more than a year. I highly recommend the discipline the results are magnificent and worth it. My friend in Toronto wants details of similar programs available in Canada, please can you advise or help? Thanks, Sally

  Eat healthy and you'll look fab.
Charnel (Verified User)

I’ve done Slender Wodner four times already. The alarm bells should be ringing at this stage lol. Like with any and all other diets out there, Slender Wonder just being super expensive, they all work while you are on the plan, the minute you stop dieting or injecting and start attempting to eat normally again the kg’s start creeping back. Face it, we are what we eat, so realistically, eat healthy and you’ll look fab.

  Loved the product.
Kas (Verified User)

With every weight loss programmes there are the pros and cons. My family has been on this programme for 8 weeks, my dad has lost 17kgs, my mum and I have both lost 9kgs. Yes we are constantly on the loo (not running to it all the time) but our bodies are getting rid of all the toxins. I feel healthy for the first time in a VERY long time I. Have all sorts of health issues that seem to be under control for the first time in 11 years. Slender wonder may not work for you, but it is changing my life one day at a time.

Slender wonder is the best
Marlise (Verified User)

Slender wonder is the best diet I ever tried, yes, commitment is highly important, but what diet would be successful without commitment? It is worth every cent
