The 10 Best Fat Burner Supplements For Rapid Weight Loss

Losing weight and getting that lean, ripped look is easier said than done.

To burn through fat, you'll need to be in a caloric deficit. That means consuming fewer calories by eating less.

But, there are also unique supplements that can help your body burn more additional calories.

I'm talking about fat burners. They're formulated with highly effective ingredients to help your body shred fat faster.

But, many products out there don't use the right ingredients or are underdosing their product, meaning they won't do much for you.

That's why we've decided to put together a list of the most effective fat burner supplements of 2020. This will help you save time, money, and effort as we've already selected the most effective products.

To present you with the 10 best and most effective products of 2020, we've gone through countless products and have tested them ourselves.

This list was created based on the following criteria:

  • Product formulation (Does it contain scientifically-backed ingredients, and are the dosages sufficient for supporting weight loss?)
  • Effects (Do you actually feel the product working once you've taken it, and how does it impact your routine?)
  • User experiences (What did other people have to say about the supplement, did they experience significant results?)
  • Company reputation (Which company has produced the product, and are they a reputable brand?)

Fat Burner Frequently Asked Questions

Do you have a question about the use, effects, or anything else about fat burner supplements? Check out our detailed, frequently asked questions section to answer any questions you might have.

Can fat burners be used safely?

Yes, fat burners can be used safely, but there are several things to keep in mind. We always advise assessing your tolerance when using a new supplement.

That means starting with a low dosage of your new product, preferably just one capsule. This is to prevent any adverse effects from happening.

If your fat burner contains stimulants, make sure to be careful when stacking it with other supplements or caffeine sources.

And if you have any medical condition, do not use these supplements before consulting with your physician.

Should I stack my fat burner with other supplements?

It's a good idea to stack your fat burner with a different supplement, such as a BCAA supplement. This is because when you're losing weight and in a caloric deficit, you're at risk of losing muscle.

That's where branched-chain amino acids can help. They've shown to help boost muscle growth and recovery. That means they're definitely worth adding to your cutting routine.

When should I take my fat burner?

It's advised to either take your fat burner in the morning or before your workout. If your product contains stimulants, you're going to want to take it as early as possible, or otherwise, it might interfere with your sleep.

When you take it before a workout, it can help you increase your workout intensity, helping you burn more calories.

How fast does a fat burner start working?

Powerful fat burners such as Eliminate will start working from the first day you take them. You'll notice a significant increase in energy, and while you won't see it directly, it helps your body burn fat even when you aren't working out.

Why should you consider taking a fat burner?

The reason why everybody should consider taking a fat burner is that they can help speed up the entire process. Nobody likes dieting for ages, and that's where a product like this can help you get things done sooner.

But that doesn't mean they're a magic pill. You will still need to eat healthily and eat fewer calories in order actually to lose weight.

Can I take pre-workout and fat burners together?

It depends on what kind of products you have and what your tolerance to stimulants is. If both your products contain a high amount of stimulants, such as caffeine, we don't recommend taking them together.

Instead, you can take a look at stim-free pre-workout supplements. You'll still get the effects of a pre, but without the stims.

What can I expect from taking a fat burner?

If you go with a properly formulated product that contains high-quality ingredients, you can expect:

  • Increased energy levels
  • Suppressed appetite and fewer cravings
  • More focus and concentration
  • Accelerated fat loss

Again, make sure to go with a good product that has plenty of positive user feedback.

When will I see a difference with a fat burner?

Generally speaking, you'll start to see a significant difference after about 3 to 4 weeks of taking a fat burner. Remember, they aren't magic pills. They just help speed up the progress.

Will a fat burner break my fast?

Pretty much all fat burners don't contain any calories, so they shouldn't break your fast. Make sure to check if the product you have on hand contains them.

What ingredients should I look for in a fat burner?

Not all ingredients that are added to fat burners are useful. That's why you need to know which one's to look for. Here are a few key elements that every weight loss product should contain:

  • Caffeine (Anhydrous or Di-Malate)
  • L-Acetyl-Carnitine (ALCAR)
  • Cayenne Pepper (Capsaicin)
  • Synephrine (Bitter orange)

These four ingredients are all good ingredients that have scientific data available to back up their effects.

Do you still have a question about these products and want one of our supplement experts to assist you? Don't hesitate to contact us and ask your question; we're happy to help.


Losing weight and dieting down can be extremely difficult. That's why sometimes, you can use some extra help by taking a fat burner.

Not all of them work, as some are missing key ingredients or underdosing their products. That's why we've presented you with the 10 best fat burner supplements available on the market.

These products will help you stay energized, prevent cravings, and optimize weight loss so that you can achieve your dream body as soon as possible.

Of course, we also highly recommend that you start tracking your macros to lose weight successfully. Working out can also create a more massive caloric deficit, speeding up the process even more.
