How Does The Underground Fat Burner Work?

Have you ever wondered why you are having trouble losing weight? It’s not that you don’t know how to lose weight. 

Despite being full, you crave food even when you have an out-of-control appetite. Matt Marshall claims that when you consume junk food, your brain triggers dopamine, which leads to more cravings. The result is an out-of-control appetite, or a runaway appetite.

Thanks to The Underground Fat Burner supplement, you’re able to reduce your appetite, boost fat burning, and achieve the kind of body you want. A powerful blend of ingredients was used to ensure the formula works as expected. Let’s examine the ingredients in a later section.

What are The Underground Fat Burner Features & Benefits?

The makers of The Underground Fat Burner claim the supplement will provide all of the following benefits:

  • Defeat “runaway appetite patterns” by crushing appetite
  • Support a healthy metabolism and accelerate fat burning
  • Kickstart your motivation, boost your mood, and sharpen your focus
  • Take your workouts to the next level while increasing your energy and preserving muscle mass
  • Lose significant amounts of weight with very little effort, diet, exercise, or hard work required to get the body you’ve always wanted
  • According to its sales page, The Underground Fat Burner is ideal for people who want to lose 10, 20, or 50 pounds within a short period of time.

The Underground Fat Burner Ingredients Review


The Underground Fat Burner’s first ingredient activates two hormones. This is peptide YY and a glucose-like peptide-1, also called fullness hormones. You will feel fuller for longer if you increase these hormones. Therefore, Fibersol delays your hunger, causing you to eat less and eventually lose weight.

You not only burn fat for long periods of time with this ingredient, but it also stimulates fat metabolism, promotes beneficial gut bacteria, enhances intestinal regularity, and reduces visceral fat and triglycerides.


A powerful ingredient that helps you burn fat faster is L-Carnitine. A fatty acid is taken to mitochondria for energy by this amino acid. L-Carnitine promotes fat burning at the cellular level, unlike Fibersol, which puts you into fat-burning mode. This combination is excellent for burning fat naturally.


It is also part of The Underground Fat Burner. In addition, it is known to improve alertness, focus, and attention. Tyrosine has been shown to improve cognitive flexibility and memory in a study involving 22 women.

Chromax (Chromium Picolinate)

Chromax has plenty of benefits for the body. In the first place, it helps you have healthy blood sugar levels by enhancing insulin sensitivity. 

In addition, the ingredient promotes a healthy metabolism and allows the body to process carbohydrates effectively. Most importantly, it minimizes hunger and cravings.

Garcinia Cambogia Extract

As an essential ingredient, this fruit extract is used. The fruit extract suppresses appetite and helps ensure fullness. This ingredient can contribute to weight loss in many studies.

Caffeine Anhydrous

According to the official website, Special Forces used this ingredient to enhance performance and awareness. As a fat-burning component, caffeine anhydrous has been included in this formula in its pure form. This ensures that it works effectively to burn fat through lipolysis.

The caffeine in pure form increases your body’s heat production, which leads to weight loss. Your muscle mass is also preserved as you lose weight.

Forskolin Root Extract

In addition to stimulating fat release, forskolin extract is found in the root of a plant in the mint family. As reported by WebMD, forskolin users lost more weight compared to placebo users, and their testosterone levels increased.

CaloriBurn Grains of Paradise

Another ginger-derived component. Research has proven that it activates Brown Adipose Tissue, which regulates metabolism and energy and optimizes body composition.


Capsimax is made from capsaicinoids, which are compounds found in red hot chili peppers. By improving body metabolism, increasing heat, and burning fat for energy, this ingredient effectively burns excess body fat.


The Underground Fat Burner contains bioperine as the last ingredient. Bioperine is responsible for increasing absorption. It ensures that all the necessary nutrients are absorbed by your body.

What is The Story Behind The Underground Fat Burner Supplement?

A man named Matt Marshall invented the Underground Fat Burner. Matt wrote an eBook entitled The Underground Fat Loss Manual, which he describes as “controversial, but wildly popular.”

He lives in Michigan with his wife and two daughters. Matt gained weight during the lockdown because Michigan was hit hard by the Coronavirus.

While working from home, Matt was also a father to his two children. Hanging around the house all day is an easy way to overeat, and Matt says he developed an overactive appetite during lockdown.

Keeping a caloric deficit is the only way to lose weight if you have an overactive appetite. You will never maintain a caloric deficit if you consume too much food.

Matt, however, claims you aren’t to blame for your overactive appetite; instead, we have overactive appetites because of these factors:

Problem #1: There’s Food Everywhere

Because there’s food everywhere when you work from home, it’s easy to overeat. It’s impossible to resist eating more food if you walk past the fridge 300 times a day. Matt explains how we are constantly bombarded by food advertisements.

Problem #2: Genetically Modified Foods Short Circuit Your Appetite

Genetically modified foods are also responsible for changing how our bodies process appetite, according to Matt. Just as junk food reduces appetite, GMO foods do the same. Food elicits the same response in people as drugs do in drug addicts.

This cycle is called a “runaway appetite pattern.” You eat more than you think you should because you think you’re hungry. Since your brain doesn’t recognize fullness, you keep eating. Over time, you gain weight when you eat too many calories for your daily caloric needs.

Matt made a change. The internet helped him solve his runaway appetite problem by ordering fat-burning diet pills. They didn’t work, however.

Rather than buy a diet formula, Matt decided to make his own. In order to cure his overactive appetite, he claims to have spent thousands of dollars on research and development.

As a result, Matt packaged multiple ingredients into a single formula, which he now sells online under the name The Underground Fat Burner, claiming it’s the ultimate weight loss aid.

How to Use The Underground Fat Burner Supplement?

The Underground Fat Burner is unlike other fat-burning supplements on the market. Put one serving of the formula in a glass of water about 8 oz. when you receive your bottle. 

Shake gently before drinking. Three things will happen to you after drinking the formula, and they are;

  • Lips and mouth will feel slightly tingly
  • It will be easier for you to complete your tasks as you’ll have more energy and alertness
  • You will notice you are not hungry after some hours. You will eat out of habit, but you will quickly realize you no longer crave food.

What is the Scientific Evidence For The Underground Fat Burner Supplement?

The Underground Fat Burner has not been the subject of clinical trials, nor has Matt published any peer-reviewed research on it. No specific evidence proves that Matt’s weight loss formula is effective, despite his claims.

Even so, most of the Underground Fat Burner ingredients have been scientifically proven to work. Diet pills sold online today contain caffeine, cayenne pepper extract, and other proven fat burners.

One of the most popular fat burners on the market today is caffeine. Caffeine works as a stimulant. It gives you energy and lifts your mood. Additionally, it is a thermogenic, which means it tells your body to burn fat. 

Rather than summarizing every study ever conducted on caffeine, read this 2019 review on the weight loss effects of caffeine. There were 606 participants in those studies that showed caffeine to be beneficial for weight loss. 

These studies found that caffeine consumption led to significant reductions in weight, BMI, and fat mass. The researchers found that this effect was dose-dependent: every doubling of caffeine intake led to greater reductions in weight, body mass index, and fat mass.

Researchers analyzed the effects of garcinia cambogia to confirm its benefits in a 2015 review study. The hydroxycitric acid (HCA) in garcinia cambogia helps you lose weight. 

Researchers have found that many of the garcinia cambogia supplements do not deliver the results they promise. Researchers warned that these supplements might be toxic in the review. 

In some studies, however, garcinia cambogia supplements (when purchased from reputable companies) have been shown to suppress appetite and increase fat loss.

The Underground Fat Burner contains one third fiber. Fiber is a popular and proven weight loss supplement. 

It will not accelerate fat loss, but it will encourage your body’s natural digestion, which will force waste out of your body. Only 5% of adults consume the recommended daily amount of fiber. It is possible to lose weight simply by pushing more waste from your body when you eat more fiber. 

In a recent review, Harvard Health described how getting more fiber can accelerate weight loss.

As a whole, The Underground Fat Burner contains ingredients that could help you lose weight in several ways. Boosting fat burning, suppressing appetite, and promoting digestion are proven weight loss methods.
