#1 Instant Knockout – Best Overall
“The best thermogenic fat burner. Completely safe and natural with fast results according to many customers.“
Instant Knockout is an innovative, awesome-looking fat-burning supplement that can help you shred weight relatively fast. 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 IKO CUT to get leaner and keep the weight off in a safe and sustainable way.
Effects that make Instant Knockout the best thermogenic:
- Potential fat loss results in 5-6 weeks
- No hunger cravings
- Preserves lean muscle tissue
- Maintains high energy levels and focus during the day
Ever since its release in 2012, Instant Knockout’s makers have constantly talked with nutritionists and pro athletes to keep the ingredient formula updated.
Instant Knockout gets updated every few years, based on the latest scientific findings.
We like this – it tells us we aren’t getting a product that lives on its past glory, but one that’s arguably still number 1 after all these years.

Instant Knockout Results
We can understand why cutting weight with IKO is surprisingly smooth and feels easy for many customers. Studies show that ingredients in Instant Knockout such as caffeine start working almost immediately.
The first change you should notice is a reduction in the appetite, followed by a stable clean source of energy that should last you throughout the day, even if you’re low on calories. This is thanks to the smart combination of several ingredients, including caffeine and l-theanine.
After about 3 weeks you may start to see the first noticeable changes in your physique and around the belly, provided you watch your diet and exercise regularly.
This is the fastest fat burner on this list in our opinion.
After those initial 3 weeks, your results might slow down a bit, especially if you have slip-ups here and there (we all do, we’re human). That said, if you keep going for 2-3 months with this product and a clean lifestyle, you’ll see some pretty impressive differences in your physique compared with when you started.
One drawback is 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.
The high-dose green tea extract in Instant Knockout is healthy for most people, but we don’t recommend it for those with liver conditions as green tea extract can lead to side effects in rare cases.
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.

#2 Hunter Burn – The High-Dosed Fat Burner for Faster Results
A high-end scientific fat burner specifically designed for men over 35.
Hunter Burn is a highly targeted fat burner that caters to a specific audience – premium, high-achieving men who need a supplement that will help them feel good and look great.
If you’re looking for a fat burner that delivers some of the industry-leading ingredients in large clinical doses, then get your hands on a supply of Hunter Burn.
It contains a generous amount of white kidney bean, matcha tea, and vitamin D3 to support muscle-building, performance, and fat burning.
While it comes at a premium price tag, Hunter Burn doesn’t compromise in any department.
It works to help you:
- Improve daily mood and mental sharpness
- Target stored fat with matcha tea – more nutrient-dense than regular green tea
- Activate thermogenesis with Cayenne
- Suppress cravings with white kidney bean
- Support immunity with vitamin D
Our Thoughts on Hunter Burn
This is a product with a tried and tested formula. You should experience a lift in focus, mood, and energy levels shortly after taking Hunter Burn.
The first visible improvements with fat burners like Hunter Burn should come after 4 weeks of use. We think combining it with calorie deficit and regular exercise will work great. You should experience a boost in energy levels and focus almost right away.
Effects you can expect over 1 month:
- A good amount of daily energy, without the jitters
- More motivated to hit the gym, and better performance with weights
- Better quality sleep
- Improved ability to sustain focus and deep work
- Solid weight loss results (comparable to Instant Knockout)
While unexpected, some users may also notice an increase in libido, thanks to vitamin D. When you think about it, this is not really a surprise – about 1 billion people worldwide are deficient in the sunshine vitamin. One of the symptoms is diminished sex drive.
The only complaint we have about Hunter Burn is the price. We understand that it’s made to deliver maximum quality, but some folks might want a cheaper option. With that said, Hunter Burn is worth the money if you can afford it.
- 6 potent and high-quality ingredients for maximum benefit
- Generous dosages (5000IU of vitamin D3)
- Scientifically backed
- 180 capsules per bottle
- 90-Day Guarantee
- Only found on the Hunter Revolve Website
#3 Burn Lab Pro® – Best Stim-Free Fat Burner
Extremely clean, standardized formula with some of the most effective ingredients on the market.
Burn Lab Pro’s patented, stim-free formula is extremely light, yet it’s so effective at burning fat that it can rival any caffeine-based weight loss pill.
In our opinion, Burn Lab Pro is the best fat burner if you don’t like the effects of stimulants and want something lighter for long-term fat loss support.
Don’t get us wrong; other fat burners are higher on this list for a reason – they have better ingredients for burning fat faster in our opinion. However, if you want cleaner effects without caffeine sensitivity issues, get your hands on a supply of Burn Lab Pro.
Burn Lab Pro’s vitamins and minerals are cultured on probiotic bacteria and yeast using the unrivaled NutriGenesis® nutrition technology. This, according to Burn Lab Pro’s makers, creates a “food-identical” nutrient with all of its essential cofactors – making it easy for your body to absorb and utilize.
Burn Lab Pro contains the essential trace mineral Chromium, which will regulate your blood sugar levels and curb cravings. Cayenne pepper is a fiery spice that will kickstart your metabolism and make you burn more fat as a result.

Dosage, price, and final thoughts
Dosage instructions: 3 capsules spread evenly throughout the day, with a full glass of water (with or without food).
Burn Lab Pro uses patented ingredients, and so it naturally costs more than some of its competitors – $59 per month’s supply.
However, buying the 3-month supply package gets you 1 extra bottle of Burn Lab Pro for free as well as free worldwide shipping. Breaking it down, Burn Lab Pro costs only $1.48 per day when you buy the 3-month package.
According to people at Opti-Nutra, Burn Lab Pro is ideal for those who exercise on an empty stomach, also known as ‘fasted’ training. With 90 capsules per bottle, you’re getting a continuous supply of fat-burning ingredients to ensure the best results. If you can afford it, Burn Lab Pro is worth trying.
