Fat Fighter Review - 6 Things You Need to Know


In my never-ending question for the best diet products, this week I reviewed Fat Fighter. We took an in-deep look at the ingredients, side effects, customer care and clinical research. Furthermore, we scrutinized hundreds of consumer comments and experiences from all over the web. Then, we condensed and summarized to give you the info you need.

What is Fat Fighter?

First off, Fat Fighter ingredients are chromium 150 mcg, NeOpuntia (cactus leaf) 500mg, garcinia cambogia fruit extract, green tea leaf extract, white kidney bean extract, bitter melon fruit extract, banaba leaf extract, gymnema sylvestre leaf extract, wheat amylase inhibitor and vanadium. [1] The supplement promotes weight-loss by blocking the absorption of carbs and fat. 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 two capsules with or 60 minutes after eating a meal. [2]

Fat Fighter is a dietary supplements sold by It Works! The business is a direct sales company founded in 2001. You can purchase the product directly from the official website. We like that is contains a few natural ingredients and that we located some positive customer comments, but read on…

Fat Fighter Side Effects – “A Problem?”

The first negative were reports of Fat Fighter side effects. “This one has some promising ingredients, like chromium and green tea,” said our Research Editor. [3] “Unfortunately, we found that others, such as bitter melon and garcinia cambogia, that are associated with negative side effects.”

One user said, “I have had pretty moderate stomach cramps with bouts of diarrhea for the past 6 days. My stomach is bloated and I haven’t lost any weight.”

I started feeling horribly bloated and had horrible constipation. I finally stopped taking them after about two weeks because I felt so fat and I was in horrendous pain,” said another customer.

Although reports of side effects are rare, they occur. Other customers had a different take.

There were no side effect, I had no jittering, no type of unpleasant symptoms,” stated a customer. [4]

Lack of Results – “Nothing Substantial”

According to customer comments, Fat Fighter ingredients didn’t help them lose weight. One customer said, “Unfortunately didn’t see any difference or results.”

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

While some users reported the lack of results, we found other dieters that shared their positive experiences using It Works Fat Fighters. [5]

“My appetite is hugely reduced. I really have only ate the last two days to live because I haven’t craved or wanted anything,” stated a customer.

“It’s not like I lost a ton of weight using this product but I am maintaining and slowly losing,” commented another.

Our research has proven that if there’s a certain part of a supplement that’s problematic, like not producing real weight-loss results, the likelihood of success for the long run is slim. In other words, if Fat Fighter doesn’t help people lose, this could be a deal breaker.

The Science – “Evidence-Based?”

The company claims to promote weight-loss by offering clinically-tested ingredients. We decided to follow the research. We found that some of components of the formula, such as prickly pear (fiber) and green tea, have been studies, but the evidence behind both doesn’t connect it to this particular supplement. At DietSpotlight, science is imperative to the review process. If there are no studies supporting claims, we start to have concerns about the supplement. [6]

What Users Are Saying

“Seems to be working great. No negative side effects, need to keep at it. starting to see results”

“I think it works for me I’ve noticed my stomach doesn’t look as bloated as it did, but it makes my bowels a little loose.”

“This product didn’t work well for me. I felt sick every time I took it, and couldn’t take it long enough to even see results, but I’m also sensitive to most products like this so this inst to say this product doesn’t work.”

The Bottom Line – Does Fat Fighter Work?

Still considering It Works Fat Fighter for weight-loss? Well, we like that it contains a few natural ingredients and that we found some positive customer comments, but we’re concerned about this one because there’s no research connecting this formula to you losing weight. Also, we’re a bit skeptical due to customer reviews talking about it causing negative side effects and not producing results.

If you really want to see results, we suggest going with a diet supplement using ingredients connected to weight-loss, proven to work and backed by positive customer feedback.

Among the best products we’ve seen this year is one called Burn HD. This supplement promote weight-loss by concentrating on four clinically-tested ingredients, which have been shown to help enhance fat loss and kick-start metabolism. Furthermore, we can’t find any complaints of harmful side effects and dieter comments found online indicate people are seeing significant results.

Also, the makers of Burn HD are confident in their product so they’re offering a 2-Week Sample, which we find a good sign.

Does Fat Fighter work?

We didn’t find any clinical research on the description page for Fat Fighter. If you take a look at the ingredient list you have two that are worth a try. Chromium has been shown to help support healthy blood glucose levels, which can help with cravings. Green tea is another good choice, but we have no idea how much is in there and because the proprietary blend contains only 510 mg, we don’t think there’s enough to match what’s been used in studies.

How much does Fat Fighter cost?

You will pay $39 for Fighter unless you are a Loyal Customer. They get the discounted price of $23. To join you have to sign up for a three-month autoship program. There are 60 tablets in each bottle. If you take the maximum number each day that will only last 10 days. One month could cost $117.

How should I take Fat Fighter?

You take two Fat Fighters up to one hour after the largest meals of the day. You can also use it if you have a high fat snack.

Can I take Fat Fighter with a fat burner?

There’s no indication that Fighter will interact with a fat burner as long as you do not take the two at the same time. Wait between one and two hours after taking Fat Fighter to take another supplement, according to It Works!

Is Fat Fighter a fat burner?

No, Fat Fighter works against fat and carbohydrates. It is not a supplement that will increase metabolism to the point you’ll notice weight-loss.

You may want to change out Fat Fighter for a formula that’s been clinically tested and proven to help with metabolism and fat loss; one like Dietspotlight Burn.

Fat Fighter: 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.

Fat Fighter Ingredients

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.

Advantages of Fat Fighter

  • 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.

Disadvantages of 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.

    It’s not a weight loss supplement. It’s a carb and fat inhibitor.

    • Anna (Editor)

      Hello. All users are different and can experience different weight-loss results, but exercise in conjunction with a healthy diet and supplements have shown to help with weight-loss.

  • Does this really help in losing weight !

    I want to get the fat fighters but nothing ever works does it really help you loose weight

    • Stephen (Editor)

      Hi, Trudy! Unfortunately the negative user reviews and lack of scientific backing leaves us questioning this product’s effectiveness. Our top product right now is Dietspotlight Burn, which is backed by clinical research and positive reviews.

  • These are not for me !
    Maria (Verified User)

    If your from a family known for touchy stomachs or previous heart burn or ibs. Do not take them. If you do you will become uncomfortably bloated, gassy, abdomen pain, vomiting(bile), Watery diarrhea, dehydrated and the sweats. Several of my friend have used them with wonderfully results. But for someone like me with a touchy stomach previous ibs as a child and a family that all has some sort of stomach issue it was not a good month. Yes I’ve tried summing down to blame things I’ve ate and done but I didn’t chnage anything the only thing that changel was taking these. They are not for everyone, and that’s ok. It works sells other products that I enjoyed but these were not for me.

  •  Fat Fighter
    Nancy (Verified User)

    The worst product I have ever tried. I had nor been taking anything at all just exercise. I was also a distributor, I decided to try them before pushing them out to my clients. the first couple of days were ok, a bit of an irritable tummy but didn’t think anything of it until I just could not stand the pain in my lower belly. it seemed each time I took it specifically as directed my stomach would bloat tremendously not to mention the uncomfortable pain. I stopped taking them and called IT WORKS to tell them about my experience and to send the product back, to my disbelief they actually wanted a Dr.’s note stating that the Fat Fighters were the cause. WOW!!! was all I could say. For the amount I paid they can take the pills and shove them …..
    Needless to say I would not recommend this product or any product from this company. Poor customer service and business practice. If you stand behind your product why not just satisfy your customer, one out of the thousands they have should not even make a dent in their business. Leads me to believe something may be wrong with their product and they need documentation to figured out what is really happening. No one’s body is the same but for me this product is not it.

  • I have never ever had high blood pressure
    Rachel (Verified User)

    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?

    • Candace (Editor)

      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.

    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.

  • Here is the product information
    Nancy Evans

    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.
