Frequently Asked Questions
Thanks for reading our article on the best fat burner supplements to buy and try. We’ve dedicated this next section to answering popular questions and covering important information before you buy a fat burner product.
These include the following:
- How we choose the fat burners on this list
- How fat burner supplements work

- Frequently asked questions
How We Choose the Best Fat Burners
A lot of thought and research goes into creating these lists, to ensure we recommend the best products possible. It’s important to mention the selections we make are based on our personal opinions and research. We are not medical professionals, and this is not to be taken as medical advice.
The way we choose the best fat burners are based on a variety of factors, which goes as follows, in order of importance:
The ingredients used in any type of supplement need to have research that suggests they will be beneficial for the intended use purpose. In the case of fat burners, there are many ingredients that have been studied for long periods of time, and may well be beneficial in aiding fat loss.
We’ll talk more about these ingredients below, but we always check for them when looking at and researching fat burners. There’s no use in having ingredients that have no backed research behind them.
Choosing the right ingredients is one thing, but providing optimal dosages for each of them is another. Many companies will lure you in with marketing that shows they include the correct ingredients in their products, yet when we look at the supplement facts breakdown, the dosages are often far too low.
This is normally done to cut costs and boost profits, so it’s crucial for us to check the dosages properly.
Most ingredients that have significant studies and research behind them will have a clinically ‘effective’ dosage. This is the recommend dosage considered to provide the desired effect.
Transparency is another important factor to consider. Companies may hide their formulas behind vague blends or mixes, which makes it difficult to see the full ingredient/dosage content.
When we research supplements, we like to see companies being as transparent as possible with their products, and providing a complete ingredient breakdown.
When you’re buying any type of supplement, the price is not a good variable to look at. What we really want to be looking at is the overall value.
The reason for this is because supplements vary in ingredients, dosages, and servings per container.
Product A is $30.00 but contains 60 servings.
Product B is $15.00 but contains 20 servings.
Product B is cheaper, but product A provides more value, costing $10.00 for 20 servings.
Then we need to look at optimal dosing. If product B was optimally dosed with all the right ingredients, but product A was severely underdosed, product B would become the better value.
Most Popular Fat Burner Ingredients
There are several ingredients included in most fat burner supplements that are proven to have effects on the body that are potentially beneficial to aiding fat loss. A good fat burner supplement should contain at least two or three of these ingredients.
- Green Tea Extract
How Fat Burners Work
Fat burners work in three main ways. The most popular and most researched ingredients in fat burners may aid in the following three areas, which in turn could help with fat loss.
Remember that no matter which supplements you lose, fat loss is achieved by eating in a calorie deficit. If you’re eating in a calorie surplus, supplements won’t make any difference.
Fat burners may help aid in making calorie deficits easier to achieve.
The only way to lose weight is to consume fewer calories than your body naturally burns on a daily basis. For many individuals, this task in and of itself proves difficult. Fat burners will often contain ingredients that help trick your body into believing it has been fed.
Your body needs energy, and whilst both muscle and fat can be sources of energy, we want to maintain as much muscle as possible whilst burning fat. As well as eating in a calorie deficit and maintaining heavy resistance training to achieve this, a fat burner can trick your body into using stored fat for energy.
Green tea extract is one of the most popular ingredients used for this purpose.
Ingredients like caffeine and capsaicin are often used in fat burners as they raise the body’s temperature. In doing so, your body has to work harder to regulate the temperature in order for optimal function. Your body burns more calories as a result of doing this.
Whilst this won’t make a huge difference, it definitely aids in helping you reach a calorie deficit.
Lastly, this section contains some frequently asked questions people have before taking a fat burner supplement. Be sure to read this before making any decisions.
Are Fat Burners Safe?
Whilst fat burners mostly use common ingredients widely considered as safe, it’s important to always pay attention to the recommended dosages. There are side effects to doing or taking too much of anything, and this is no exception. Many fat burners also include caffeine, which is an addictive drug and can cause mild side effects with heavy consumption.
Do I Need A Fat Burner?
Fat burners are not needed in order to lose fat. You lose weight simply by eating fewer calories than your body burns on a daily basis. Taking a fat burner supplement without making any changes to your diet or lifestyle will provide zero results.
That being said, they may aid slightly in reaching that calorie deficit by suppressing appetite and helping the body burn slightly more calories than normal.
Do I Need to Diet When Using A Fat Burner?
If we assume that you normally eat the same amount of calories you burn on a consistent basis, then yes, you would need to diet when using a fat burner. Fat burners do not burn fat. Period. Ironic, I know, but they can aid in reaching a calorie deficit.
Should I Consult A Doctor?
We always recommend consulting a doctor before making any additions to your diet, lifestyle, or supplement regime. We are not medical professionals, and if you ever have any questions or concerns about using a fat burner supplement, speak to a professional first.
We hope you enjoyed our list of the 15 best fat burners.
As I mentioned before, it’s difficult for most people to lose fat whilst retaining muscle, so using a thermogenic fat-burning supplement, like any of the ones on our list, will certainly increase your chances of success and help you achieve your goals a lot faster!
