Fat Killer Review - Does This Diet Pill Actually Work? Are hefty price tag and lack of real results deal breakers?

Editor's Review: 3.1 / 5.0

fat-killer-product-imageNo joke – over 50% of diet products simply don’t work. So what about Fat Killer? There’s been plenty of chatter about these pills, so we wrote a comprehensive review, examining the ingredients, side effects, customer care and clinical studies. Plus we took a look at numerous dieter comments found all over the web. Finally, we compacted the data we found to give you the information you need.

EDITOR'S TIP: Substitute Fat Killer with a proven fat burner such as Leptigen for better results.

What You Need To Know

To begin with, Fat Killer is a European weight-loss supplement that appears to be made in Austria or Germany. This one aid is primarily marketed to women. Fat Killer capsules contain vitamin B5, garcinia cambogia, African mango, green coffee bean, guarana, L-carnitine, white willow bark, green tea extract and Korean ginseng. This “slimming pill” claims to burn off fat three times faster and target problem areas such as the midsection. It should be taken daily, as two capsules, for maximum results. No specific diet or exercise plan is mentioned.

Fat Killer has been around since 2013, and it does contain some natural ingredients, great choice. Also, this supplement is for people of all sizes and it provides antioxidants, but read on…

The Price Tag – “Ouch?”

Our first consideration with Fat Killer ingredients was the price. “It looks like the actual cost of Fat Killer diet pills, after shipping and handling, is about $100 per bottle, which is a one-month supply. This is certainly not affordable for many people trying to lose weight,” says our Research Editor.

According to one dieter, “Too expensive for me, and I can’t even tell if it works.”

Another user said, “Better off just eating less. It’s a lot cheaper.”

Scroll below for one of the best products we’ve seen in 2015.

Lack of Real Results – “No Loss”

From what we gathered, there are quite a few complaints about dieters simply seeing no results. One customer stated, “Are you sure this pill actually works??”

“Don’t see the weight loss! It’s been four weeks now!,” said another dieter.

Our research has revealed if there is some individual facet of a diet pill or fat-loss program that is very concerning (serious side effects, high price, no real science) the chances of success is quite minimal. Therefore, if Fat Killer pills do not yield real weight-loss results in numerous people, this could be a big problem.

The Science – “Clinically Proven?”

There is no real clinical study presented for Fat Killer pills. In fact, we could not even locate an official website, which means this weight-loss product has likely been discontinued. Here at DietSpotlight, we need to see actual science to support the diet supplement’s claims. When no dedicated information is available, there’s no reason for dieters to try this one on for size.

The Bottom Line – Does Fat Killer Work?

Well now, what’s the final take on this one ladies and gentlemen? It’s important to be cautious when shopping around for a weight-loss product. The reality is many of them are not backed by any real research. This appears to be the case with Fat Killer pills. We also noticed that this aid contains fad diet ingredients such as garcinia cambogia. Moreover, there is no official website for Fat Killer.

Those who really need to shed more pounds and get into shape faster, we recommend you select a diet supplement that is both affordable and backed by actual clinical studies.

Among the best products we’ve seen in 2015 is one called Leptigen. It contains a unique blend of four key ingredients, which have been shown in documented scientific research to help kick-start metabolism and encourage more fat loss. We have not discovered any talk of negative side effects and user reviews around the internet show people are seeing excellent results.

Also, the formulators of Leptigen are so very sure of their product they’re offering a Special Trial Offer, which is a good sign.
