It Works Fat Fighter Review: Does It Really Work?

Written By : Dr Ruby Shah   ✓ Fact Checked

Fat Fighter by It Works! is reputed to block carbohydrates and dietary fat, enabling a dieter to continue to lose weight while enjoying decadent foods.

(Last Updated on November 21, 2023)

It’s now well established that the key to losing weight1 is to control the effects of carbs and blood sugar.

Unless you can do those things, it doesn’t matter how careful your diet is or how much exercise you do.

Now there’s a dietary supplement that claims to actually be able to fight the absorption of dietary fats and inhibit carbohydrate fat storage.

It’s called Advanced Formula Fat Fighter.

Sound too good to be true?

In this Advanced Formula Fat Fighter review we provide you with the full story to allow you to make your own informed decision.

What Is Fat Fighter?

Advanced Formula Fat Fighter is a dietary tablet.

It is intended to prevent the absorption of dietary fat.

Other ingredients in this product are designed to inhibit the absorption of carbohydrates.

When these nutrients are prevented from being absorbed, they will not release their calories into the body but will be eliminated from the body.

It should be noted that the makers of Advanced Formula Fat Fighter do not claim that it will prevent all fats and carbs from being absorbed.

That is important because both of these macronutrients are essential for overall health.

Advanced Formula Fat Fighter is marketed by the Multi Level Marketing company IT Works.

The product line of this company includes energy boosters, health shakes and detox formulas.

These products are sold through an army of distributors.

It Works prefer that customers purchase through their distributors.

To encourage this, they offer discounts off the website price.

If you do decide to buy off the website, you need to do so with caution as you may inadvertently be signing yourself up for monthly billing.

At this time, the Better Business Bureau have received in excess of 400 complaints about It Works, with a lot of them revolving around their Autoship program.

The company has a C+ rating from the Better Business Bureau.

Fat Fighter Ingredients


There are ten ingredients in Advanced Formula Fat Fighter.

Eight of them are combined in a proprietary blend.

That means that we have no idea of the exact ingredient dosage of eighty percent of the ingredient profile.

Here are the key specs on the six main ingredients in this product.


NeOpuntia is one of the two ingredients where the dosage is listed.

You get 500 mg of this extract from the prickly pear cactus per dose (two tablets).

It is believed that NeOpuntia binds to fat, preventing it from being absorbed.


Chromium2 is the other ingredient that’s dosage is disclosed.

You get 150 mcg of this mineral. It is known to help with weight loss by increasing satiety and helping to prevent cravings.

Chromium also reduces LDL cholesterol levels, boosts heart health and helps to modulate brain function.

Bitter Melon Fruit

The fruit of the bitter melon vine3 is packed with antioxidants, vitamins and minerals to promote health.

Studies suggest that it also has the potential to help people lose weight, especially the dangerous visceral body fat that surrounds the body’s organs.

It may also have the ability to boost the metabolism to further encourage weight loss.

It should be noted, however, that all studies to date have been conducted on rats and mice, so no conclusive statements can be made until human trials are conducted.

Vanadyl Sulfate

Vanadyl Sulfate4 is a trace mineral that is mainly recognized as a strengthener for the teeth and bones.

It is also known to help in the reduction of LDL cholesterol levels.

However, its main inclusion here is due to its purported ability to regulate blood sugar levels by mimicking the action of insulin to encourage the cells of the body to more quickly absorb glucose.

Though this ingredient is part of the proprietary blend, it is listed last which may indicate that it is at the smallest dosage.

That would be a good thing as vanadyl sulfate is known to be toxic at high levels.

Gymnema Sylvestre

Gymnema Sylvestre is supposed to assist in weight loss, especially when it acts in concert with garcinia cambogia and chromium, both of which are also in this product.

However, the study that this is based on used dosages of the three ingredients that combine to more than the total proprietary blend of all 8 ingredients in Advanced Formula Fat Fighter.

In other words, we can be pretty sure that the amount of gymnema sylvestre in this product is insufficient to have an appreciable effect.

Green Tea Leaf Extract

Green tea leaf extract5 delivers a calm energy boost by way of the combination of caffeine and the amino acid L-theanine.

The amino acid regulates the caffeine so that its well-known stimulatory effects are not pronounced.

Other Ingredients
  • Garcinia cambogia
  • Wheat amalyse inhibitor
  • Banaba leaf extract

How Does Fat Fighter Work?

The key active ingredient in Advanced Formula Fat Fighter is NeOpuntia.

It contains natural fibers which have lipophilic properties.

That means that they have the ability to bind to the fat from the foods in the stomach.

The result of this is that some of the fat in the stomach is not absorbed.

Instead it is bound to the NeOpuntia and excreted from the body.

The other active ingredient in this product is white kidney bean extract.

This extract is known to act as a carb inhibitor.

It has the ability to paralyze the enzyme in the stomach that converts starch from carbs into sugar.

As a result, these carbohydrates are not absorbed and they, too, are excreted from the body.

It should be emphasized here that It Works do not claim that Advanced Formula Fat Fighter will stop the absorption of ALL fats and carbs.

As a result, this product should NOT be seen as a way to eat whatever fats and carbs you want and think that you won’t get fatter!

How To Use It?

how to use

Advanced Formula Fat Fighter should be taken about fifteen minutes after your largest meal of the day.

Each dose consists of two tablets.

You should also take two tablets fifteen minutes after having a high fat snack.

For best results, It Works recommend taking six tablets per day, which is three dosages.

With 60 tablets in the bottle, your bottle will last for 10 days.

Fat Fighter Side Effects

All of the ingredients in Advanced Formula Fat Fighter are completely natural.

That allays fears of any major side effects.

However, some users have reported the following:

  • Diarrhea
  • Stomach bloating
  • Constipation
  • Nausea

Iy Works provide a number of guidelines and warnings with this product. These include:

  • It is only suitable for people aged 18 years and over.
  • Pregnant women or those trying to get pregnant should not use the product.
  • Advanced Formula Fat Fighter should be cycled off after eight weeks for a couple of weeks.
  • You should not drink alcohol when taking Advanced Formula Fat Fighter.

33% are 5 Star, giving it a 3.0 rating overall.

The general consensus from the reviews is that Advanced Formula Fat Fighter does reduce appetite and helps to fight cravings.

However, it did not work in terms of weight loss for some people.

The following reviews are from Amazon.

Galia writes:

I have tried many weight loss supplements and formulas without success. I am half way through the bottle and so far feel that my appetite is less. It has some heat effect because it results in a excessive sweating shortly after taking the 2-pills doze. Unfortunately, it gives me acid reflux. I am determined to continue using it for a total of 3 bottles to determine how well it works for me.

Sandofabeachtx reports:

I took 2 pills on my 2 largest meals of the day which is lunch and dinner. If I have it within 60 minutes to take the pill, i would wait 30 minutes to use it. I felt the differences in myself already. When it’s a slow day at work I would snack a lot and I mean a lot on fruits. I still eat the food I love but not as much (as an big portions of food). I can see that I am loosing weight on my belly! It has gotten flatter. I can feel the difference in my pants, it felt like it’s sliding down my legs. My face is getting thinner. I’m feeling GREAT! I went from size 3 to size 2 in 9 days! Still eat the food I love. It’s BEEN GREAT!!!! Even though I love how it got my stomach flatter. IN ORDER FOR YOU TO MAKE IT WORK AND LOOSE Weight is to DRINK LOTS AND LOTS OF WATER … if you plan on drinking drinks that have sugar in it , don’t plan to buy it and waste your money. Otherwise it works .

However, Shelley Kruimer did not notice much difference, writing:

Did not see a difference in my weight ate properly and did minimal exercise on 1450 calorie diet.
