It seems like not a day goes by without another weight loss supplement hitting the market with lofty promises of that perfect beach body.
I’m an eternal skeptic when it comes to these products, and GAT Jetfuel is one of the latest products that our clients and readers have asked about.
And we always give these supplements a fair chance with one of our dietitians and some team testing.
As part of this review, we’ll give you details about the ingredients in the formula, potential side effects, and how and if it actually works.
Let’s dive right in.
What Is GAT Jetfuel?
GAT Jet Fuel is a fat-burning supplement that uses natural ingredients to help boost your metabolism and provide appetite suppression. It may also help users achieve their fat loss goals faster than through exercising and dieting alone.
So, they are upfront about the fact that this isn’t a miracle diet pill that allows you to eat donuts all day while binge-watching Netflix.
In addition to possibly helping with those love handles, it claims to feature energy-boosting ingredients as well.
When you combine higher energy levels with some appetite suppressants, then you might have a product that suits people from a bodybuilding or just health-conscious background.
Who couldn’t do with an energy boost without reaching for that snack drawer, right?
As with all these fat burner supplements, it all comes down to the content.
And this is what our dietitian had to say.
GAT Jetfuel Ingredients
Our trusted dietitian Susan spent several hours with us presenting her research information about the long list of ingredients in this weight loss supplement.
DMAE stands for dimethylaminoethanol, and I have no idea how to pronounce it. But there is some research that has linked it to better athletic performance for weight management.
Overall, the scientific community is still undecided about how effective it is and what the best dose would be.
2. Caffeine Anhydrous
Caffeine is a common ingredient in fat burning supplements, and there is no shortage of scientific evidence that it may boost your thermogenic metabolism . Just keep in mind that it contains approximately 200 mg, which is more than a cup of coffee, and the stimulant could mess with your sleep.
If you're dealing with coffeine side effects, we recommend you to check out stimulant-free fat burners.
3. Guarana Seed Extract
This is another one of the stimulating ingredients, and you might be familiar with it from sports drinks.
Some companies claim that it may provide a mental and physical boost, but we haven’t found enough evidence to support the athletic boost.
4. MCT Oil Powder
We were a bit surprised by this one because it’s not common for a fat burner product. I regularly use MCT for my bulletproof coffee, which is a good way to get some brain power, but it’s not really going to do anything for your metabolism.
5. American Ginseng Root
Our dietitian mentioned that this is often used in traditional Chinese medicine to support the faster breakdown of body fat. But we also found some information to suggest that it might prevent new fat tissue from developing .
6. Bitter Orange Fruit Extract
This is one of the ingredients we’d be a bit cautious of. There is some evidence that it might help with losing weight, but it also contains synephrine, which has been linked to increased heart rate, headache, and dizziness .
7. Yohimbe Bark Extract
Quite a few of our fat burner product reviews have included this bark. Some studies have linked it to fat breakdown and weight loss, but it seems to be a more suitable supplement as an appetite suppressant.
8. Sodium Starch Glycolate
This ingredient we couldn’t quite figure out, as there’s no science supporting it in fat burning supplements. So if any of our friends and readers have an idea, then please let us know.
This unpronounceable ingredient may provide some benefits to your stress levels through better cortisol regulation. And stress has been linked to weight gain, so it might be a positive compound of the formula.
10. Acetyl-L-Carnitine (ALCAR)
Research on ALCAR for weight management is a bit mixed. But we have found evidence that it may help to boost brain power, focus, and motivation .
“Studies show ALCAR increases mental energy and brain function, lowers inflammation, boosts circulation and improves focus.” - Spencer Brooks, Writer at Bulletproof.com.
11. Rhodiola Root Extract
This is another one of the positive ingredients as it’s a supplement that dietitians regularly recommend for weight management. The big question is whether there’s enough in each capsule to support your workouts.
12. Hoodia Gordonii Stem Extract
It’s believed to have some impact on weight loss by increasing the effectiveness of your metabolism. But studies have been a bit split in their research, especially in the double-blind ones where it didn’t prove very effective.
13. Magnolia Bark Extract
Our dietitian’s experience with magnolia bark is limited, but she thinks that claims of fat reduction might be overhyped.
There’s also limited evidence that it might improve stress and overall mood, so we’d have some questions and reservations about it.
This is one of the better ingredients, and you might be familiar with it from drinking green tea. If you have a low-calorie diet and boost your L-Theanine intake, then it could make your dieting efforts easier by burning more fat.
We’ve had a few recommendations from nutritionists about 5-HTP, and a good serving of it has been shown to reduce hunger cravings. And not reaching for the snack drawer could have a big impact on your dieting efforts.
16. Green Tea Extract
Green tea is something we probably should all be drinking more of, but having it in a supplement capsule might make it a lot easier. Not only is it good for antioxidant delivery, but you might also find it's a decent thermogenic booster.
17. Black Pepper Extract
Black or cayenne pepper extracts are common in supplements as they have been shown to boost nutrient absorption in your stomach. That may mean that the GAT Jet Fuel blend could start acting faster.
Overall, the ingredients list is a bit hit and miss. There are quite a few positive ones in the blend, but also a few where weight loss details and study results are mixed.
“In particular, experts have looked into the ability of piperine—the organic compound that gives black pepper its appealing piquancy—to increase the body’s absorption of curcumin and resveratrol.”
- Markham Heid, Writer at Time.com.

How Does It Work?
GAT Jetfuel works by increasing both your mental and physical energy with its caffeine component. It may also help you deal better with hunger. Finally, some of its ingredients may act as a powerful fat burner that increases your metabolic rate.
The recommended serving size is three capsules one to two times a day. For most people, once a day should be a good starting point.
First of all, using this product might give you quite a mental and physical boost of energy throughout the day. Like other dietary supplements, some of this boost is due to a high concentration of caffeine per serving.
Whether it’s a long-lasting energy boost is debatable, as people tend to process caffeine differently.
Based on our dietitian's feedback, that might be a bit overstated. Some of the supplement content is backed by science (e.g., caffeine), but not to the extent that we’d call it powerful.
Pros and Cons
So, we did hear from a few folks that they were able to extend their fasting times in the morning without having that starving feeling.
We also liked the convenient capsules that you could bring with you to work or other activities for a more convenient way to take them.
The main issues we had were down to some of the chosen ingredients.
There’s a high dose of stimulants, and combined with synephrine from bitter orange, it could result in higher blood pressure.
It’s something you may want to monitor.
P.S. If you're a woman, we recommend you to check out these female fat burners.
- Some positive effects about it helping with fasting
- Easy to take capsules make it more convenient
- Medium-chain triglycerides (MCT) may boost mood
- Some of the fat burner ingredients are not backed by science
- Quite a high dose of caffeine might make you jittery
- Combination of caffeine and synephrine might raise heart rates
Where Can You Buy It?
You can buy GAT Jetfuel directly from the company website and from some online retailers. However, be careful when buying from resellers because we've heard from many folks who had trouble with some of their supplement purchases.
With so many fake supplements out there, you have to make sure you don’t end up with something dodgy, and buying directly is the safest way to do so.
Any Side Effects?
Taking GAT Jetfuel may have potential side effects, including palpitations and upset stomach.
That's why you always have to be careful when it comes to side effects, especially in supplements containing many different ingredients in the blend.
Our first stop was our dietician, and overall she thought the suggested servings should be safe for most people.
The main negative was the high caffeine amount combined with synephrine, which could cause a rapid heartbeat.
So, any of our readers with any kind of medical condition or taking heart medication should check with a doctor first.
We also noted a few online comments where folks said they had some initial stomach discomfort in the first couple of days.
So, if you are planning to try this supplement, then maybe take a smaller dose for a few days.
We’ve picked out a few online review comments to show you some cases where people confirmed our own findings.
Michel reported good weight loss results over a ten-week period. He got the best effects with two doses a day but had to reduce it again as he felt jittery and struggled with getting to sleep. - Michael from Providence
Abbi struggled with the stimulant effect a lot even when she reduced the capsules based on the directions on the label. She just felt jittery for a few hours after taking them and switched to a non-stimulating supplement.
- Abbi from Orange County
He used GAT Jet Fuel for a cutting phase and found it seemed to help him extend his fasting periods. It also seemed to work reasonably well as a fat burner. - Stuart from DC
Tony had been struggling with his dieting efforts and thought that GAT Jet Fuel did help him reduce his snacking. He also thought it helped him to work out more effectively, which seemed to have contributed to some extra weight loss. - Tony from Raleigh
How Long Does It Take for Gat Jetfuel to Work?
It takes about 30 to 60 minutes for GAT Jetfuel to work. However, you may need to wait four weeks to notice the weight loss on the scales as the herb and protein ingredients take a while to build up in the body.
Does GAT Jetfuel contain stimulants?
Yes, GAT Jetfuel contains stimulants in the form of caffeine and guarana. This is common for a dietary supplement, but you have to make sure that you account for the stimulant effect if you don’t want it to mess up your nighttime sleep.
Should You Try This GAT Sport Product?
While we do think that GAT is a good brand, we didn’t quite get the same levels of fat-burning as we have with a few other products.
And when you add in the stimulant side effects noted by our dietitian, then it’s also not the safest option we’ve encountered.
That’s why we still recommend PhenQ to all of our clients and readers.
We have seen the best impacts on people’s weight goals especially with its unique set of fat burning and thermogenic ingredients, along with practically no negative effects.
