Fat Fighter Review - Does This Dietary Supplement Really Work? Are negative user reviews and lack of real weight-loss results deal breakers?

Editor's Review: 2.5 / 5.0


In my never-ending question for the best diet products, this week I reviewed Fat Fighter. We took a deep look, focusing closely on the ingredients, side effects, customer care and clinical research. We also scrutinized tons of consumer comments and experiences from all over the web. Finally, we condensed all of the data we collected to give you the info you need.

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

What You Need To Know

First off, Fat Fighter is a diet supplement made by Only Natural, Inc. It contains oat bran concentrate, rice bran concentrate, psyllium seed husks, apple pectin, glucomannan, carrot fiber, beet fiber, L-acidophilus, cascara sagrada, lecithin, choline bitartrate, inositol, L-carnitine, chromium picolinate, aloe vera, spirulina, bromelian, coenzyme Q-10, calcium, magnesium and potassium. This product claims to lower bad cholesterol levels, speed up the metabolism of fats and promote good bacteria in the digestive system. Directions say you need to take 2-3 tablets with eight ounces of water, five minutes before each meal.

From what we can tell, Fat Fighter has been available since 2011 and it sells on the official website for $22.99. This supplement provides some fiber and it is free of yeast and sugar, but read on…

Negative Customer Reviews – “A Problem?”

The first consideration dieters need to make with Fat Fighter ingredients is that customers are not sold on them. According to our Research Editor, “While doing some looking online, we noticed quite a few negative reviews. This is never a good sign. Users have complained about the size of these tablets, how many you have to take daily and that they do not actually work.”

One user said, “What a waste of money. These pills are so huge. I did try to stay with it by cutting the pill in half. I didn’t lose weight at all.”

“9 tablets a day is just too many, and the bottle is only good for 2 weeks,” said another customer.

Weight-Loss Results – “Nothing Substantial”

We were unable to find any solid research or studies to support Fat Fighter tablets. One customer had this to say, “Unfortunately didn’t see any difference or results.”

Another user commented, “Not good for weight-loss. Kind of like a fiber supplement.”

Our research has proven that if there is a certain part of a supplement or diet program that is very problematic (lack of real weight-loss results, too many negative customer reviews, very high price) the likelihood of success for the long run is slim. In other words, if Fat Fighter tablets do not help people lose, this could be a deal breaker.

Did We Find Any Science?

Unfortunately the official website does not provide any clinical research to support Fat Fighter tablets. Furthermore, we could not pinpoint any solid science pertaining to the ingredients used in this weight-loss supplement. While the fiber may help with regularity, it’s unlikely to help you lose more. Here at DietSpotlight, we prefer to see documented studies that support claims, but we were disappointed this time.

The Bottom Line – Does Fat Fighter Work?

So, shall we take a final look at this one? First of all, we appreciate that this company has been around since 1986. On the other hand, we definitely have reservations about recommending this one to dieters, because there is no clinical proof it will help with weight-loss. This supplement is basically like a fiber powder or pill. It may help increase regularity, but we don’t believe it works in any other way. Furthermore, you have to take 9 tablets per day, which is a lot.

If you really want to see results, we recommend you go with a diet supplement that uses clinically proven ingredients, is backed by positive customer reviews and comes with excellent customer service.

Among the best products we’ve seen in 2015 is one called Leptigen. This diet supplement contains four ingredients, which have been proven in documented clinical studies to help enhance fat loss and kick-start metabolism. Furthermore, we can’t find any complaints of adverse effects and dieter comments found online indicate people are seeing significant results.

Also, the makers of Leptigen are confident in their product so they’re offering a Special Trial Offer, which we find a good sign.

What You Should Know

There does not seem to be an official website for the weight loss product Fat Fighter, and so all of the information about this supplement is derived from online stores that are selling it. Fat Fighter is produced by Only Natural, and those vendors that are selling it say that the fat fighter formula has been combined with enzymes, minerals and acidophilus, and that all of the ingredients are necessary to maintain a healthy intestinal tract. They further claim that Fat Fighter will give you the fibre necessary to generate a full feeling. They say also that in taking Fat Fighter you will see greater general nutritional value in terms of overall diet.


The ingredients in Fat Fighter consist of: Oat Bran, Rice Bran, Psyllium Husk Seeds, Apple Pectin, Glucomannan, Carrot Fibre, Beet Fibre, L-Acidophilus, Cascara Sagranda Extract, Lecithin, Choline
Bitartrate, Inositol, L-Carnitine, Chromium Picolinate, Aloe Vera, Spirulina, Bromelain, Co-Enzyme Q10, Calcium, Magnesium and Potassium.

Product Features

There is no official website for Fat Fighter but it can be bought from a number of online health stores for the price of $17.59 for 120 tablets per bottle. Those selling Fat Fighter say that you should take two or three tablets with eight ounces of water, three times a day on an empty stomach, five minutes before your meal. Of course Fat Fighter is not the only product on the market that claims to be able to improve the state of you intestines and your overall digestive health in addition to stimulating weight loss. A number of the ingredients in Fat Fighter are certainly known for their beneficial effect on the digestive tract, and for their fibrous qualities. L-Acidophilus, we know, helps to introduce good bacteria into the digestive tract, and bromelain is well known to help with digestion. However the ingredients in Fat Fighter are ones that are also found in similar products on the market.

  • We do know that some of the ingredients in Fat Fighter are beneficial for digestive health.
  • Fat Fighter can be ordered directly online.
  • There is a comprehensive list of ingredients available for Fat Fighter.


  • The money-back return policy and other customer service policies associated with Fat Fighter are unclear.
  • There is no official website for Fat Fighter.
  • The product manufacturer is completely unknown.
  • The manufacturers of Fat Fighter do not provide any data regarding how their product is different from other, similar products on the market.


At the end of the day competition between manufacturers of weight loss products is tough. Although Fat Fighter falls into a specific niche, since it claims also to improve digestive health, it is not the sole product on the market making these claims. The manufacturers of Fat Fighter will have to work harder if they want to convince us that it is superior to other, similar supplements that are currently available.

    This is y 2nd month of doing this and I think this is what is causing my high blood pressure. I have never ever had high blood pressure and now all of a sudden every time I take this I experience weird stuff and have had my blood pressure checked and sure enough it was high. Has anyone experienced this?

    Rachel, this is interesting you say this if this review. We’ve not heard a case of it happening. We suggest you stop taking it until the discomfort subsides or seek your doctor’s attention.

    Your review doesn’t seem to match the product I have. It is It Works! Global TM Advanced Formula FATFIGHTER with Carb Inhibitor, because the ingredients you listed are not the formula listed on my bottle. It seems to be a fatbinder similar to FBCx. It Works! Global has several individual distributors with websites. I just wanted to come to your site to get a review of the product that wasn’t by one of the distributors, so maybe you might look a little bit more. It comes in a black bottle with silver and green print.
    I am sure your review isn’t for the product that myself and Nancy Evans (below this box) mentioned since the ingredient do not match up at all.

    I received my Fat Fighter supplement with the It Works wrap, and the bottle states that It Works Global is the mfg.


    Andrea Bramblett

    I am a distributor, Fat Fighter is clearly made by It Works Global and this does not match anything on the It Works bottle


    Precious Peck

    I have the bottle in my hand and you are correct this profile/review for fatfighters is not the same.
