Ready to kick off the New Year with a bang? Here’s our top 3 fat burners list (now updated for 2021)! If you already aren’t familiar with them, so-called fat burners are food supplements that help support the loss of weight by raising metabolism, reducing cravings and helping the body use more fat as fuel.

Our top fat burners have all been roadtested for weeks to ensure they’re completely clear of any risky or synthetic ingredients. We base our list on:

  • Fast, lean physique results
  • 100% natural formula
  • Clean energy
  • Appetite reduction
  • Healthy mood & focus
  • Long-term safety
  • Company trust

The following fat burners also have the ability to optimize your workouts by boosting energy and focus, which can be especially useful during caloric restriction.

We’ve done research on over 35 most popular fat burning supplements this year, comparing them against each other to see which is the best value. The result of our search has allowed us to present the top 3 fat burners on the market right now.

#1 Overall – ShredCBD

shred cbd number 1 fat burner

ShredCBD is an effective, side-effect-free solution to burning unwanted fat and feeling leaner. CBD plays a crucial role in your body’s endocannabinoid system (ECS). Which is why supplementation works so well. It’s completely different from any other product on offer right now.

CBD helps you shred down in 5 different ways:

  • Triggers fat ‘browning’ to help the body use fat as fuel
  • Promotes insulin sensitivity to prevent weight gain
  • Significantly reduces cortisol, a stress hormone linked to fat accumulation
  • Improves mood and sleep quality – aiding the mental aspect of dieting as well!
  • Interacts with brain’s ECS receptors to influence appetite and reduce calorie consumption

CBD in ShredCBD comes as pure hemp isolate, meaning it’s under 0.1% THC, non-psychoactive (doesn’t make you high), and completely legal in the USA.

Green tea and Garcinia Cambogia are added to augment fat oxidation effects of CBD. Plus, they provide antioxidants to boost your immune system and keep you healthy.

What makes ShredCBD stand out from the rest is that it shows amazing potential not just for fat loss, but has been shown to improve sleep, mood and overall life quality too.

Our Results

This is a high grade supplement that even after a couple of days led to some apparent changes in focus, mood and appetite.

In terms of weight loss, you can expect to see results after around 30 days, especially if you use ShredCBD’s power to exercise and focus on a whole-foods diet.

Effects over 2-5 weeks:

  • Good fat loss (as much as other high-rated fat burners)
  • Reduced appetite
  • More energy
  • Better sleep and focus

ShredCBD has no dodgy stimulants in it either, so there’s no risk of side effects or insomnia.

The Good

  • A potent 40mg of pure CBD Isolate per day (1200mg in a whole bottle)
  • CBD alone delivers more benefits than many other fat burner ingredient blends can.
  • 50mg of Garcinia Cambogia and Green Tea to aid further weight loss
  • Free Fast Shipping across the USA
  • Free 24-page weight loss ebook (the producers say it’s typically worth $10)

The Bad

  • ONLY available in the USA
  • Premium price due to the high manufacturing processing cost of CBD isolate.
  • You can only get it directly on the official website

#1 Thermogenic and #2 Overall – Instant Knockout

The best fat burner with caffeine. Completely safe and natural with fast results.

Instant Knockout is an innovative, cool looking fat burning supplement which can help you shred weight fairly quickly. It was originally developed for MMA fighters by Roar Ambition, a specialist company based in the UK but operating worldwide.

This product boasts excellent reviews and some of the best ratings out of any fat burner. Both men and women have been using to get leaner and keep the weight off in a safe and sustainable way.

Effects that make Instant Knockout the best thermogenic:

  • Significant levels of fat loss in 5-6 weeks
  • No hunger cravings
  • Preserves lean muscle tissue
  • Maintains high energy levels and focus during the day

What’s unique about Instant Knockout is that its manufacturers constantly talk with nutritionists and pro athletes to keep their formula updated.

Specifically, Instant Knockout gets an update every 6-12 months, based on the latest scientific findings.

We like this – it tells us we aren’t getting a product that was launched years ago and forgotten about.

Our Results

Cutting weight with IKO was surprisingly smooth and felt easy. It starts working almost immediately.

The first change we noticed was a reduction in our appetite, followed by a good clean source of energy that lasted throughout the day despite being low on calories.

Instant Knockout Guarantee
Instant Knockout’s money-back guarantee (we haven’t used it).

After about 3 weeks we started to notice changes in physique and around the belly, which was a bit unexpected!

This is the fastest fat burner we’ve tried.

After those initial 3 weeks, the results slowed down a bit, but we did slip up here a few times. That said, if you keep going for 2-3 months with this product you’ll see some pretty impressive differences in your physique compared with when you started.

One annoying drawback was that it’s only available directly from the manufacturer’s website, and the price is a bit high, but it’s kind of expected from a product of this quality.

Four capsules per day might seem annoying as well, but keep in mind that this will prolong the fat burning effects throughout the entire day, meaning you won’t have any ‘downtime’ in effects between doses.

Three months cutting with IKO, 3 day a week training, and a fairly clean diet.

The Good:

  • All-natural and healthy ingredients
  • 90-day money back guarantee – among the best in the industry
  • Provides long-lasting, clean energy
  • Effective fat burning
  • Suppresses cravings
  • No hidden ingredients or proprietary blends
  • Discounts when you buy in bulk
  • Available worldwide
  • Excellent reviews

The Bad:

  • Premium price when buying only 1 box
  • Only buyable direct from Instant Knockout’s website
  • Not for people who’re extremely intolerant to caffeine
