How We Decided

When it comes to finding the best fat burner supplements for athletes, there are a few key factors that we looked at:


Ingredients are easily the most important factor when grading a fat burner or any other supplement.

We made sure all of the supplements on this list used effective ingredients that have been shown to help with fat loss in clinical trials.

We made sure the fat burners weren’t just caffeine pills pretending to be fat burners that try to trick you into thinking they are working by giving you a lot of energy.

We also ensured that they avoided using proprietary blends, so you know exactly what you are getting with each serving.


The next most important thing we looked for was dosage. Some fat burner supplements will have a great list of ingredients to make themselves look good but will skimp on the dosages, which make the product much less effective.

You have a winning product if you have a fat burner with good ingredients and solid dosages. The problem is, those products are few and far between.


While all of the products on this list are effective, some are more affordable than others. We considered price when making our selections but it wasn’t the only factor we looked at.

We believe you don’t have to spend a lot of money to get a good fat burner supplement, but you do get what you pay for most of the time.

The more expensive products on this list tend to use better ingredients and have higher dosages which is why they cost more.

User Feedback

We also looked at user feedback when creating this list. We believe that the people who use these products are the best judge of how well they work.

Of course, there will always be some haters no matter how good a product is, but we tried to focus on the overall consensus.

If a fat burner supplement has many positive reviews, it is likely a good product worth considering.

Manufacturer Reputation

We looked at the manufacturer’s reputation when judging these thermogenic fat burners.

We only included products from Supplement companies with a good reputation and are known for producing quality products.

You can always look up a company online to see what customers have to say about them and get a feel for their reputation.

Ingredients to Look For in Fat Burner Pills

We just talked about the importance of the ingredients when it comes to natural fat burners. Here are some of the best ingredients to look for:


Caffeine is one of the most popular and effective ingredients in fat burners. It helps to increase energy levels, improve mental focus, and can even help to boost your metabolism.

Green Tea Extract

Green tea extract is a very common ingredient in fat burner supplements. In multiple clinical studies, green tea has shown to be effective for fat loss.

This study shows that green tea decreases fat synthesis, and increases the breakdown of fat, and increases the utilization of glucose.

CLA (Conjugated Linoleic Acid)

CLA is a type of fatty acid that has been shown to be effective for fat loss in multiple clinical studies. It is believed to work by reducing fat storage and increasing the amount of fat that is burned for energy.

This study shows that CLA supplementation reduces body fat mass in overweight and obese adults.


Forskolin is a popular ingredient in fat burners. It is believed to work by increasing the amount of fat that is burned for energy.

This study found that forskolin reduces fat and increases lean muscle mass in obese men compared to placebo. Then there is also this 12-week study that showed forskolin to be effective at helping obese people lose fat.

Green Coffee Bean Extract

This is another ingredient that is quite common in weight loss supplements because unroasted coffee beans are high in Chlorogenic Acid. This acid has been shown to be possibly effective in the “inhibition of fat absorption and activation of fat metabolism in the liver,” which means it may help reduce stored fat.


5 HTP is a popular ingredient in fat burners because it is believed to help increase serotonin levels in the brain. Serotonin is a hormone that is associated with feelings of happiness and well-being.

It has also been shown to possibly be effective for weight loss by reducing appetite and food intake.


Glucomannan is a root extract that is often used as a dietary fiber supplement. This fiber expands in the stomach, making you feel full, which means you will eat less and consume fewer calories, leading to more significant weight loss.

Cayenne Pepper

If you take a look at the ingredients in the best thermogenic fat burner out there, you will find Cayenne Pepper on the ingredients list. This is because Cayenne Pepper contains capsaicin which has fat-burning properties.

Capsaicin has been shown to be effective for weight loss by reducing fat storage and increasing the amount of fat burned for energy.

These are just some of the many ingredients that you will find in fat burner supplements. When it comes to fat burners, the ingredients are just as essential, if not more important, than the brand.

Dosage and Timing

When it comes to fat burners, dosage and timing are very important. You want to ensure you take the proper dosage and take it at the right time for maximum effect.

Most fat burners recommend that you take 1-3 capsules daily. It is best to start with the lower dosage and see how your body reacts before increasing the dosage.

Regarding timing, taking fat burners 30-60 minutes before meals is best. This will help reduce hunger and cravings and help you utilize the fat-burning ingredients better.

How Do Thermogenic Fat Burners Help you Lose Weight?

Thermogenic fat burner supplements help you lose weight by increasing your body’s natural ability to burn fat. They work by stimulating thermogenesis, which is the body’s heat production process. When your body temperature increases, your body works to cool itself off which burns exta calories.

Thermogenic fat burners usually contain stimulants such as caffeine, green tea extract, and cayenne pepper, which can help increase thermogenesis. Thermogenic fat burners are a great way to lose weight and get rid of stubborn fat. However, it’s important to remember that they should be used in conjunction with a healthy diet and exercise plan for optimal results.


Side Effects for Fat Burners

When it comes to weight loss pills and natural fat burners, the most significant side effect you will find is from stimulants like caffeine.

Stimulants can cause side effects like:

  • Anxiety
  • Jitters
  • Insomnia
  • Headaches

If you are sensitive to stimulants, you may want to avoid fat burners containing them. Many Stimulant-free fat burners on the market can still be effective.

There are also a few other side effects that have been associated with fat burners, including:

  • Upset stomach
  • Diarrhea
  • Cramping

These side effects are typically mild and go away on their own. If you do experience any severe side effects, stop taking the fat burner and see a doctor.

How can I get the best results from fat burning supplements?

Some people think taking a fat burner is all you have to do to lose weight unfortunately, there is more to it than that. You will also need to eat a healthy diet and exercise regularly.

A fat burner can help you lose weight by increasing your metabolism, reducing hunger, and helping you to utilize fat for energy better. But, if you are shoving pizza and cheeseburgers in your face all day, then there isnt a weight loss supplement on Earth that will help you. A fat burner is not a magic pill that will cause you to lose weight without any effort on your part.

To get the best results from fat burners, make sure you are:

  • Eating a healthy diet that is lower in calories
  • Exercising regularly
  • Taking the proper dosage
  • Timing your fat burner correctly
