  • Boost calorie burn – with potent doses of proven thermogenics in the mix to boost metabolism, help you burn all day long and achieve a shredded physique

  • Sustained energy lift – Caffeine and L-theanine make up a smart caffeine combo to deliver a natural boost in energy without any crashing or fatigue

What can you expect from Instant Knockout Cut?

Instant Knockout Cut works to be the supportive fat complex anyone would need on a cut. It takes the worry out of a weight loss process, taking control of your hunger, energy levels and the way your body burns fat.

Whether you need help controlling your calories, an energy lift to keep dominating your workouts or a natural thermogenic boost to help shed weight, Cut should deliver.

It’s clear to see that the creators have combined some of the most proven fat burning components available on the market. These ingredients come together to support a healthy diet and training regime and help you achieve real weight loss results. Working alongside your routine, it should also build healthy habits and help you keep the fat off for good.

Instant Knockout Cut ingredients

Instant Knockout Cut is composed of 9 all-natural ingredients. Each element warrants its place within the complex, showing positive signs of fat burning support. After inspection our team also found no hint of unnecessary fillers.

At first, we were sceptical about whether such an expansive profile such as this could deliver. Yet, when cross-referenced with relevant studies, we discovered every ingredient to be well-served. Additionally, Instant Knockout Cut’s caffeine content sat comfortably within the range of effectiveness, without causing call for concern.

In short – Instant Knockout Cut offers one of the best ingredient profiles we’ve seen as reviewers.

Green tea extract

A popular bitter drink enjoyed around the world, green tea is an essential addition to Cut. According to numerous studies it can help fight fat from more than one angle.

Firstly, green tea is dense with bioactive polyphenols known as catechins, which have a positive influence on weight loss [6]. Additional studies state that it can provide thermogenic effects and increase calorie burn through caffeine content [7] [8].

In addition to raising resting metabolic rate, green tea can also influence fat burning by providing energy for exercise. The clean hit of caffeine found within this bitter leaf should help users side-step fatigue caused by calorie restriction.

Cayenne Powder

This potent pepper provides Cut with a powerful thermogenic boost. Like all chilis, cayenne contains capsaicin, a bioactive alkaloid that raises the core temperature of the body, alongside fat oxidation and metabolic rate [9].

Furthermore, additional research suggests that supplementing with capsaicin can bring about positive changes to blood-sugar management systems. When used in this way, the thermogenic compound may help fat loss by influencing the way your body utilizes carbohydrates [10].

To bolster the benefits of cayenne powder, scientists say it can also improve satiety. Therefore, the inclusion of this capsaicin-rich compound could be considered another appetite controller provided by Cut [11].


Unlike other ingredients which might directly impact fat burning, glucomannan takes a different path. Instead, this natural fiber of the konjac plant expands slightly while in the stomach, which should create a sense of fullness.

According to Instant Knockout Cut, this complex carbohydrate has a beta-D glucose and beta-D-mannose structure, meaning it cannot be digested. Therefore, in theory, glucomannan can help to improve satiety, without adding to your daily calorie intake.

Research has shown that glucomannan alone can support better weight loss [12]. By combining the sensation of satisfied hunger with Cut’s thermogenic properties, you may experience faster fat loss.

Caffeine Anhydrous

Instant Knockout Cut should assist you throughout the day with a consistent stream of energy. One of the most valuable players in this game is caffeine anhydrous – an ingredient supplied at a powerful, yet appropriate 350 mg.

Backing up the energizing efforts of green tea, this form of caffeine is one step ahead. According to the International Society of Sports Nutrition, caffeine anhydrous overtakes the likes of tea and coffee in terms of ergonomic effects. The ISSN’s research suggests it’s especially advantageous for both maximal endurance and high-intensity sports [13], therefore, it could be beneficial for your bouts of fat burning exercise.

Furthermore, caffeine is a powerful psychoactive compound commonly utilized across the globe. Including it within Instant Knockout Cut’s mix may help you remain focused and experience a cognitive boost, especially when calorie intake is low [14].

Finally, caffeine is a known thermogenic [15]. This metabolic raising effect adds another powerful punch to Cut’s high fat burning potential.


When combined with caffeine, L-theanine works to smooth out any energy crashes and block the jitters. This results in a clean energy lift, which should keep you energized all day. The amino acid is commonly found in green and black tea and is thought to help promote a calming, relaxing response in humans. It’s also known for improving sleep quality, so you can feel well rested and ready to push your body to its maximum the next day [20].

How to take Instant Knockout Cut

Effective fat loss is a process that requires weeks to months of dedication. Regardless of how hard you diet or what supplements you take, it doesn’t happen immediately.

First, you must be in a calorie deficit, so your body turns to its fat stores for energy. Next, by exercising, you can increase your total daily energy expenditure, meaning the demands for these reserves is higher. Finally, by consistently supplementing with a fat burner like Instant Knockout Cut, you can positively influence both calorie burning and appetite, alongside supporting your body with healthy vitamins and minerals.

Planning how and when to take Instant Knockout Cut is important for unlocking its many potential benefits. For example, the appetite controlling compound found within it can help stop overeating, which is why this fat burner should be taken around meal times.

One daily distribution of Cut to four capsules. However, rather than taking them all together, this amount is split into four servings.

To experience the true potential of Instant Knockout Cut we recommend:

  • Take one capsule immediately after waking, before breakfast
  • The second between breakfast and lunch
  • Your third serving one-hour after lunch
  • A final capsule 60-minutes before dinner

According to the manufacturer, it’s also important to drink a full glass of water with each serving. Not only will this help your body digest each ingredient, but it’ll allow the appetite suppressing glucomannan to expand. This should work to keep cravings at bay and stop overeating.

Instant Knockout Cut suggest you take your final capsules at least five hours before bed. This will ensure there’s adequate time for the caffeine content to be processed without it impacting sleep. If you’re sensitive to caffeine, we recommend you extend this time period, as well as reducing your daily intake.

To establish a level of safety do not take more than the recommended amount of this product. Failure to comply to manufacturer guidelines may negatively impact your health.

Instant Knockout Cut benefits

Instant Knockout Cut’s primary objective, as with all fat burners, is to change your body composition. The result should be lower body fat in relation to muscle mass, which may also be accompanied by weight loss.

As a premium fat burner, this supplement should support a fat loss journey by providing energy alongside noticeable reductions in appetite. After review, Instant Knockout Cut is undeniably on target.

Raised metabolic rate

No high-quality fat burner is complete without an element of increased metabolism. Simply put – you burn more calories than you would without it.

Instant Knockout Cut should achieve this by utilizing numerous research-backed thermogenic compounds [1]. Alongside, the inclusion of sunshine vitamin D3 provides even more of an opportunity to target stubborn fat by blocking the production of fat cells and suppressing lipid storage [16].

Together, these integral ingredients combine to create a complete fat-loss support complex, resulting in higher calorie expenditure and less body fat. Together, these integral ingredients combine to create a complete fat-loss support complex, resulting in higher calorie expenditure.

Energy support  

One side effect of a calorie restricted fat loss diet is a lack of energy. Therefore, it is integral that a reputable fat burner provides an additional boost to help combat fatigue.

By including the likes of caffeine through two pathways in safe, crash-free servings, Instant Knockout Cut may provide a vital lift. Whereas many lesser-quality substitutes overuse caffeine, this premium product favors exclusively well-researched servings, delivered via the additional avenue of green tea. The added L-theanine works well with caffeine to deliver a clean lift, with improved alertness, drive and energy [17] while beating off negative side effects like ‘jitters’.

Ultimately, users should feel the energy to take on their fat-loss workouts, while enjoying mental focus and clarity in the workplace [2] [3].

Appetite management

The only way anybody can successfully burn fat is to achieve a calorie deficit [4]. Energy expended throughout the day must outweigh that taken on by food.

Consequently, caving in to cravings and overeating can sabotage your goals, doing damage that no supplement can undo.

Instant Knockout Cut clearly understand this underestimated pitfall, so have added the expanding fiber glucomannan to their formula. Once ingested this should help curb appetite by creating feelings of fullness.

Support muscle maintenance

Fat burners can often focus too heavily on cutting pounds, often at the cost of body composition. This shallow, low-quality approach usually results in physical repercussions, including muscle wastage.

However, Instant Knockout Cut have accounted for the potential unwanted side-effects of this practice. They instead forward plan to protect your physique by supplying vital vitamins and muscle maintaining minerals.

Mood boosting

Cut’s fat fighting formula aims to make the weight loss process that little bit easier and with added mood boosting elements, you should find yourself with better motivation and drive to succeed. With vitamin D3 in the mix, your serotonin levels are increased, warding off low mood and keeping you on track [18]. Alongside, L-theanine’s stress-fighting abilities help to reduce anxiety and insomnia significantly [19].
