It Works! is a well known multi-level marketing company operating across the USA and beyond.

It Works! Fat Fighter Overview

What you need to know about It Works! Fat Fighter

It Works! Fat Fighter is marketed as a carb and fat blocker. The idea is that you take it when you eat fattening food or shortly after so that you can enjoy overindulgence without it adding to your weight.

However, there is no evidence that this will work. In addition, the supplement contains many ingredients that are believed to reduce blood sugar levels, but there is no real proof that it will achieve this aim. Fat Fighter comes from US direct marketing company, It Works!

What are the side effects of It Works! Fat Fighter?

Some people have complained of increased hunger and dizziness as well as bloating, abdominal pain, stomach cramps, diarrhoea, constipation, and indigestion.

Other side effects may include nausea, headaches, gas, loss of energy, green tongue (vanadium), low blood sugar, fatigue, and changes to menstrual bleeding.

How much does It Works! Fat Fighter cost?

This supplement is expensive and the price will depend on how and where you buy it. Purchase directly from the official It Works! website as a retail customer and Fat Fighter costs $39.00 for 1 x bottle of 60 capsules (one month’s supply).

This price is reduced to $23.00 if you become a “loyal customer “ and sign up for auto billing. Distributors will also get a reduction.

You can also buy It Works! Fat Fighter via an It Works! distributor or Wrapaneur as they are sometimes called. Prices will vary depending on your individual distributor. One of the easiest ways to buy It Works! Fat Fighter is via Amazon USA, where it costs $38.99 per bottle of 60 capsules.

It Works! Fat Fighter Key Features

It Works! Fat Fighter is a weight loss supplement that you are advised to take during or after a fatty or carb-rich meal. Although this does look a bit like bolting the stable door after the horse has bolted, this supplement contains natural fibre ingredients that according to the advertising, will block some of these fat building components from adding to your body weight.

It Works! Fat Fighter Key Points

  • On sale from It Works! – A multi-level marketing company
  • Each bottle contains 60 capsules or 30 servings
  • Contains ingredients that may affect blood sugar levels

The principle ingredient is a proprietary blend of ingredients. This means that although we can see the names of the ingredients, we are not told ingredient quantities. Contents include a white kidney bean extract – often used in carb blockers, green leaf tea, and Gymnaema sylvestre leaf – a tropical herb believed effective as a treatment for diabetes because it blocks the taste and effects of sugar.

The supplement also contains a trademarked cactus supplement called NeOpuntia, a naturally based ingredient made from the “prickly pear” cactus and believed to be effective at blocking dietary carbs.

The whole topic of carb and fat blockers is debatable. Although this method of weight loss sounds appealing, not all so-called carb and fat blockers are effective and some are well known for side effects.

Blocking carbs can work in the way as described, but if you rely on this effect, it may lead to overeating in the belief it will not count. It seems better to avoid eating fattening foods in the first place, rather than eating them first and then taking a supplement to clear up the damage.

How to Take It Works! Fat Fighter

Take 2 capsules during or up to 60 minutes after a large meal. Drink at least 8 glasses of water daily.

From Amazon:

“One to two Fat Fighters should be taken 15 minutes to 1 hour after eating your two largest meals of the day or after snacks with a higher fat content. Maximum of 4 Fat fighters per day.”

We have covered It Works! in a previous investigation. This MLM company offers you a way to set up a home business by selling supplements and establishing your own network of sellers (downline). However, we found that the promises of riches are not very likely and in our previous investigation, felt that this so-called business opportunity was one to avoid.

The principle product is The Ultimate Body Applicator, a body wrap that is supposed to take inches off your waist and improve skin tone. We covered It Works! Thermofit – a fat burning weight loss supplement in a previous review.

It Works! Fat Fighter Concerns

  • Could interfere with medication and diabetes treatment
  • May cause side effects
  • Inadequate ingredients profile – no individual ingredient quantities

What does It Works! Fat Fighter claim to do?

The advertising outlines what this supplement is all about,

Have a sweet tooth? A carb craving? It’s okay to indulge every once in a while when you have Advanced Formula Fat Fighter with Carb Inhibitors!

Simply take Fat Fighter up to an hour after eating, and it will absorb some of the fat and carbohydrates from your food so that your body doesn’t.

The big word here is “some”. How much fat and how many carbs does it block? This is not disclosed.

The ingredients are explained, but very briefly.

Powered by NeOpuntia™ (a naturally based ingredient made from the “prickly pear” cactus) and the It Works! proprietary blend, Advanced Formula Fat Fighter delivers dynamic, clinically tested results for both men and women.

However, this “dynamic “clinical testing is never detailed.

According to the product advertising, there are five key benefits.

  • Blocks some of the fat & carbs from meals
  • Helps balance healthy blood glucose level and reduce cravings
  • Designed to be taken up to an hour after meals
  • Cactus-based formula
  • Does not contain shellfish

Does It Works! Fat Fighter work?

With such limited product information, it is hard to assess just what this supplement will do. It may bring down blood sugar levels following a meal but if you are diabetic, we do not advise that you rely on this effect. It could be dangerous. It may help prevent some weight gain if you use it very occasionally for high carb high-fat meals, but in our opinion, it may feel like a licence to overeat.

And with zero real information about the sort of results you can expect, we can’t see this supplement being very effective for weight loss.

It Works! Fat Fighter Ingredients

Serving size is equal to 2 capsules.

  • Chromium (150mcg): Trace mineral that may be effective as a treatment for diabetes because it may help regulate blood sugar levels by improving the way the body used insulin. Source
  • NeOpuntia™ cactus leaf (50mg): Branded supplement derived from dehydrated cactus leaves that may help increase HDL cholesterol (good cholesterol levels). Prickly pear cactus is rich in fibre and pectin, so may help lower blood sugar levels by decreasing absorption of glucose. Source

Proprietary blend (510 mg):

  • Garcinia cambogia fruit extract containing Hydroxycitric acid: Widely touted natural acid that is believed to block an enzyme in the body called citrate Lyase which helps the body make fat. There may be some truth in this theory, but better clinical studies are needed.
  • Green leaf tea extract (20% caffeine): Clinical research has found that green tea has proven health benefits and the antioxidants (ECGC and polyphenols) found to have anti-obesity and fat burning properties because of the effects upon the metabolism. However, this weight loss effect does not work on everyone and will depend upon your own physical makeup and the amount of tea you habitually consume. Quantities here are unknown.
  • Phaseolamin: This is a generic name for a substance derived from white kidney bean extract which some studies suggest may inhibit Alma amalyse – an enzyme in the body found in saliva that breaks down food into starches. Delaying this process delays digestion keeping you feeling fuller for longer, but clinical testing seems to prove this does not work very well unless you already eat a very high carb diet. Requires more testing. Source
  • Bitter melon fruit extract: Plant extract, also known as African cucumber or Momordica charantia. It is believed to lower blood sugar levels but requires more testing both for efficacy and safety. It is known for causing side effects. Quantities unknown here.
  • Banaba leaf extract: This looks a very promising ingredient for the management of diabetes. This plant extract can inhibit uptake (digestion and absorption) of carbohydrates, and can also aid in their deposition into cells from the bloodstream (resulting in a reduction in blood sugar). However, the effective dose seems to be around 3000mg when taken with meals. Source
  • Gymnaema sylvestre leaf extract: The investigation into this plant extract is in early stages, but Gymnaema sylvestre may help decrease sugar absorption and increase insulin levels. However, it lacks any real evidence.
  • Wheat amalyse inhibitor: Amalyse inhibitors prevent starches from being absorbed by the body by preventing the digestive enzymes from breaking them down to be absorbed. This type of amalyse inhibitor is derived from wheat protein. May help prevent blood sugar levels rising after a starchy meal. Source
  • Vanadium: Chemical element that may increase the effects of insulin. Known for causing a wide range of side effects. Source

It Works! Fat Fighter Customer Feedback

There are many customer reviews for It Works! Fat Fighter on the Amazon USA website alone. Interestingly, customer opinion seems to be pretty evenly divided between negative comments and positive comments.

However out of 321 reviews in total, only half of these are from people with verified purchases – the people who have actually purchased the supplement. That said there are some positive comments.

This customer felt that it was good for occasional use,

I only use it on things that are more fat or carbs than I should have eaten.

Another customer felt the same when it came to ice cream,

Definitely does what it’s supposed to. Don’t waste it on every meal, ‘IT WORKS’ works for me! I love my ice cream, but it will pack on the pounds like nothing else. This product works to block the majority of those fat calories …

Not everyone is as happy. There are a lot of negative complaints. Some people have noticed no difference between taking it and not taking it, such as this reviewer.

This did nothing for me, literally. There really is not much else I can write than that. It has no effect when taking it to worry about and it ended up having no results for me after finishing the bottle…

Some customers have complained about side effects,

Still having diarrhoea I will never take this again,

Other people have mentioned the same. Some people have complained it caused them to feel hungry,

I tried this product without success. I seemed more hungry than normal so I stopped taking it. Yes, I ate a healthy diet and did light exercise.

Others have complained of issues such as bloating, constipation, headaches, and flatulence.

I was bloated/constipated for DAYS. I tried once a week for over a month and it did it every time. Maybe my body just had an odd reaction to these pills. The other It Works stuff I purchased was great so this was a bummer. However when I want a fatty meal, I would rather do a bit more exercise than feel bloated and constipated for days..

It Works! Fat Fighter Money-Back Guarantee

There does not appear to be a money-back guarantee offered for this supplement. However, if you buy from a distributor you may be able to get your money back if you are dissatisfied.

Where To Buy It Works! Fat Fighter

You can buy It Works! Fat Fighter via the It Works website. Alternatively, you can find a distributor and buy directly from them.

It Works! Fat Fighter is also on sale via Amazon USA, which is probably the easiest and most hassle-free option.

Watchdog Verdict

We are not impressed with It Works! Fat Fighter. This supplement lacks any real information about how it will help you lose weight and the lack of ingredients information means that you will not really know what you are taking anyway. There are just too many unknowns with this supplement.

Although some of the ingredients are being investigated as methods for reducing blood glucose levels this has not yet been proven. In addition, it is supposed to block carbs and fats, but there is just no evidence that it will work in the way as described. A large number of customers have reported zero weight loss effects from taking this supplement plus there is a high incidence of reported side effects.

In our opinion, It Works! Fat Fighter is just not good enough to bother with.
