Does The Underground Fat Burner really work? How does this weight loss formula work? Find out everything you need to know about The Underground Fat Burner today in our review.
The Underground Fat Burner is a weight loss aid sold exclusively online through UndergroundNutritionCo.com.
The weight loss aid is designed to target appetite and fullness. By taking The Underground Fat Burner daily, you can feel fuller throughout the day, which means you naturally eat less.
The supplement was created by a man who struggled with his weight and appetite for years. That man describes his issue as a “runaway appetite pattern.” The Underground Fat Burner claims to solve this pattern by manipulating your hormones, helping you feel less hungry.
The Underground Fat Burner contains fiber, caffeine, herbal extracts, and other ingredients to help you lose weight.
Some of the ingredients make you feel full, helping you naturally eat less. Others block the formation of fat, increase calorie burning, or boost your metabolism. Some just energize your body, making it easier to exercise and stay active.
Fiber – like the kind of fiber in Metamucil and other supplements – enters your digestive tract and absorbs water, forming a gel. This gel pushes waste out of your body, helping you maintain regular digestion. Doctors recommend getting 25 to 35g of fiber per day, although The Underground Fat Burner contains just 2.5g of dietary fiber (in the form of Fibersol-2).
The Underground Fat Burner is more than just a fiber supplement. The formula also contains a surprisingly strong dose of caffeine (225mg). That’s approximately the same amount of caffeine in two large cups of coffee. It’s more caffeine than an average energy drink.
The Underground Fat Burner also contains ingredients found in other diet formulas, including Garcinia cambogia extract, green coffee bean extract, forskolin, and cayenne pepper, among other popular weight loss aids.
The maker of The Underground Fat Burner claims you can experience all of the following benefits after taking the supplement:
Crush appetite and defeat “runaway appetite pattern”
Accelerate fat burning and support a healthy metabolism
Boost your mood, sharpen your focus, and kickstart your motivation
Increase your energy levels, preserve muscle mass, and take your workouts to the next level
Get a “shortcut” to the body you’ve always wanted, losing a significant amount of weight with limited effort, exercise, dieting, or hard work required
According to The Underground Fat Burner’s sales page, the supplement is ideal for anyone who wants to lose 10, 20, or 50 pounds in a short period.
The Underground Fat Burner was created by a man named Matt Marshall. Matt wrote an eBook called The Underground Fat Loss Manual, which he describes as “a controversial but wildly popular book on getting lean quickly.”
Matt lives in Michigan with his wife and two daughters. Michigan was hit hard by the coronavirus, and Matt gained a lot of weight during the lockdown.
Matt was juggling work from home while also being a dad to his two kids. It’s easy to overeat when hanging around your house all day, and Matt claims he developed an overactive appetite during lockdown.
An overactive appetite is a problem: the only way to lose weight is by maintaining a caloric deficit. If you eat too much food, then you’ll never maintain a caloric deficit.
Matt, however, claims an overactive appetite isn’t your fault; instead, many of us have overactive appetites because of the following problems:
Problem #1: There’s Food Everywhere: It’s easy to overeat when working from home because there’s food everywhere. You walk past your fridge 300 times a day, and you’ll inevitably eat more food even if you have good willpower. Matt describes how we’re also bombarded by food advertisements everywhere we look.
Problem #2: Genetically Modified Foods Short Circuit Your Appetite: Matt also blames genetically modified foods for changing the way our bodies process appetite. GMO foods short circuit our appetite just like junk foods. Some studies show food triggers the same response as drugs give to drug addicts.
Matt calls this cycle a “runaway appetite pattern.” You think you’re hungry, so you eat more. Your brain doesn’t know you’re full, so you continue eating. Eventually, you’ve overeaten too much food for your daily caloric needs, and you gain weight.
Matt decided to make a change. He ordered fat-burning diet pills off the internet to solve his runaway appetite problem. None of them worked, however.
Matt decided to make his own diet formula. He claims to have invested thousands of dollars in researching and developing the cure for an overactive appetite.
To make a long story short, Matt packaged multiple ingredients into a single formula, and he now sells that formula online as The Underground Fat Burner, claiming it’s the ultimate weight loss aid.
The Underground Fat Burner contains a surprisingly long list of ingredients, most of which are found at strong doses. There are powerful doses of caffeine, chromium, and other ingredients in The Underground Fat Burner.
Matt claims he carefully picked each ingredient based on its proven weight loss effects. Each ingredient is linked to different benefits. Here’s how Matt explained each ingredient in The Underground Fat Burner and how it works:
L-Tyrosine: Matt claims the L-tyrosine in his formula will help regulate mood, improve alertness, and boost attention and focus, among other benefits.
Chromax: Chromax is a patented form of chromium picolinate. The Underground Fat Burner contains a significant dose of chromium, many times higher than your daily recommended minimum. Matt used this dose because he believes chromium regulates blood sugar and that many athletes are deficient in chromium.
Garcinia Cambogia: Garcinia cambogia has been a popular diet-pill ingredient for years. Matt claims he added garcinia cambogia because it suppresses appetite and makes you feel full.
Caffeine: The Underground Fat Burner contains a large dose of caffeine (225mg). Matt added caffeine for its ability to enhance performance and awareness while encouraging the body to burn more fat.
Forskolin: Forskolin root extract is another popular diet pill ingredient. Forskolin may increase fat burning and suppress appetite, among other effects.
Grains of Paradise: Grains of paradise is an ancient spice that we don’t typically see in weight loss formulas. Matt claims the grains of paradise in his formula can activate brown adipose tissue (BAT) fat, burning stubborn fat around your belly and thighs.
Cayenne Pepper Extract: The Underground Fat Burner contains cayenne pepper fruit extract, the active ingredient in chili peppers. Many diet pills use cayenne to boost thermogenesis (fat burning).
Black Pepper Extract: Matt added black pepper extract to boost the bioavailability of other ingredients in The Underground Fat Burner. Black pepper extract could raise bioavailability by 2,000%, according to some studies.
Matt publishes the full list of ingredients and dosages upfront, making it easy to see what’s in The Underground Fat Burner and check how it compares to other supplements. Each 6g scoop contains a sizable dose of most ingredients listed above.
Oddly, Matt does not list the inactive ingredients upfront. We don’t know if Matt used natural or artificial flavors or sweeteners in the formula, for example, or what types of preservatives, fillers, binders, and other ingredients are in the formula – if any.
Matt has not completed any clinical trials on The Underground Fat Burner, nor has he published his research in any peer-reviewed journal. Although Matt claims his weight loss formula leads to significant weight loss results, no specific evidence proves it works.
Nevertheless, most of the Underground Fat Burner ingredients are backed by scientific evidence showing they work. Caffeine, cayenne pepper extract, and other ingredients are all proven fat burners found in many diet pills sold online today.
Caffeine is one of the most popular and proven fat burners available today. Caffeine is a stimulant. It energizes your body and mind. It’s also a thermogenic, which means it tells your body to start burning fat. Instead of summarizing every study every performed on caffeine, read this 2019 review on the weight loss effects of caffeine. In that review, researchers found studies with 606 total participants connecting caffeine to weight loss benefits. In these studies, caffeine intake led to significant reductions in weight, BMI, and fat mass. Researchers found these effects were related to dose: every doubling of caffeine intake led to greater reductions in weight, BMI, and fat mass.
In this 2015 review study, researchers analyzed the effects of garcinia cambogia to verify its benefits. Researchers found that garcinia cambogia was rich with an ingredient called hydroxycitric acid (HCA) that could help you lose weight. Studies show that garcinia cambogia supplements advertise huge weight loss results – yet many of them don’t work. In the review, researchers cautioned that these supplements had “possible toxicity” associated with them. Other studies, however, have found that garcinia cambogia supplements (when purchased from reputable companies) can suppress appetite and accelerate fat burning.
One one-third of The Underground Fat Burner consists of fiber. Fiber is a popular and proven weight loss aid. It won’t accelerate fat burning, but it will encourage your body’s natural digestion, forcing waste out of your body. Only 5% of adults get their recommended daily intake of fiber. By raising your fiber intake, you could lose weight just by pushing more waste out of your body. As Harvard Health explained in a recent review, getting more fiber is one of the easiest changes you can make to accelerate weight loss results.
Overall, The Underground Fat Burner contains ingredients that could help you lose weight in multiple ways. These ingredients accelerate fat burning, suppress appetite, and encourage digestion – three proven ways to lose weight.
The Underground Fat Burner is priced at $33 to $50, depending on how many bottles you buy.
Each bottle contains 48 servings (48 scoops, 6g per scoop). You take 1 to 2 servings daily to lose weight.
The Underground Fat Burner is only available in one flavor: tropical.
