Overview
In this review, we will be looking at a variety of different fat burners. Some will focus on increasing your metabolism to burn more calories, while others will focus on suppressing your appetite, making it easier to operate in a calorie deficit. But none of the fat burners are as effective as Instant Knockout Cut at performing both tasks.
Instant Knockout Cut was first developed for fighting sports such as boxing and MMA, where aggressive cuts (dropping body fat) are a crucial part of the pre-fight training. Fighter’s need to operate in a calorie deficit, they need to train hard and focus.
Cut allows this to happen. Not only does it help to rev up your metabolism and reduce your appetite, but it also devotes itself to boosting your mood and increasing focus. It offers:
- Appetite suppression
- Metabolic boost
- Fat oxidation during exercise
- Improved mood and focus
- Fully dosed ingredients
Key Ingredients
Cut contains a lot of smart ingredients. Most of the work is performed by the 300 mg of caffeine and the 1800 mg of glucomannan. There is also 500 mg of green tea extract, and 1800 IU of vitamin D. Cayenne pepper is effective at raising your metabolism and improving insulin sensitivity [1]. The caffeine is well dosed, but due to the serving being split into four pills you should not see any side effects from it.
The green tea is well dosed and should help with fat burning as well as improving blood flow. It can also help to increase HDL (good) cholesterol while lowering LDL (bad) cholesterol [2]. Black pepper extract is added to increase absorption, and l-theanine is added to improve your mood, reduce stress [3], and due to its synergistic relationship with caffeine.

How to take
For best results, you want to take one capsule four times per day. For example, one at 8am, one at 11am, one at 2pm, and one at 5pm.

If you go to bed early, then take your fourth pill before 3pm rather than 5pm as it contains caffeine.

Overview
The final fat burner on our list is Burn Lab Pro. Another stim-free fat burner, which focuses on appetite suppression and raising your metabolic rate via capsicum and chromium. The number one focus for Burn Lab Pro is to help you to maintain muscle and energy levels while dieting, which is a unique approach, and one that will suit some people really well.
The ingredients list is interesting, and offers the following benefits:
- Natural fat burning
- Thermogenic, to boost your metabolism
- HMB preserves muscle while in a calorie deficit
- Controls appetite and optimises insulin
What’s in it?
The main ingredient in Burn Lab Pro is Coleus Forskohlii. There is evidence that it can help to burn fat and may help to boost natural testosterone production in overweight males [9]. That same study saw a minor increase in lean muscle mass alongside the fat burning and testosterone boosting effects.
Coleus Forskohlii also appears to improve cholesterol levels, increase energy, and improve bone density. All of these benefits were noted in the same study, and it would be useful for there to be more follow up studies in the future. We’ve looked at capsicum in the previous entries, and we like it as a fat burning ingredient.
You’ve also got HMB which has some good evidence for burning body fat, a study on female judo athletes found statistically significant drops in body fat over a 7 day period [10]. Burn Lab Pro also provides chromium, which can help to reduce appetite (particularly for carbs) and also has mood boosting properties [11].

Want to try Burn Lab Pro?
How to take it
The website recommends taking Burn Lab Pro 15 minutes before you exercise and says you should take 2-4 capsules. The idea is to preserve your muscle and increase fat burning during the workout itself.
Pros
- Preserves muscle mass during weight loss
- Carb and food cravings suppressed
- Fat burning from capsicum and HMB
- Improved bone density
- Good price
Cons
- Doesn’t burn much fat compared to others
- Too reliant on Coleus Forskohlii
- No mood enhancing ingredients
Conclusion
There is a lot to love about Burn Lab Pro, it puts a lot of effort into preserving muscle mass during a weight loss period, and it is designed to work well with exercise. But for a fat burning supplement it doesn’t do enough to actually burn fat! Capsicum is a decent ingredient, but the other supplements on this list use it alongside other well-known fat burning ingredients. Whereas Burn Lab Pro is over reliant on it.
It also puts a lot of faith in Coleus Forskohlii, which admittedly has a lot going for it, but not much scientific evidence, just one creditable study. This makes it hard to assess, because usually you want a bit more evidence backing your ingredient before you place it as the number one ingredient in your supplement.
