Appetite Suppression

Instant Knockout Cut contains a very high dose of glucomannan to suppress appetite and reduce cravings, helping you steer clear of calorie-dense foods. Other ingredients also play a role in suppressing appetite, such as cayenne and caffeine. 

Increased Thermogenesis/Metabolism

There are many ingredients in here to also kickstart your metabolism into overdrive and boost thermogenesis to help you shred off fat. Caffeine, green tea extract, black pepper extract, and cayenne are all involved here.

Improved Energy and Mood

Instant Knockout Cut also has ingredients designed to support your energy levels and mood, such as theanine, B-complex vitamins, and caffeine, so you can have better, longer-lasting workouts and also enjoy the fat loss process more easily. 

Fat Loss

And, of course, all of these factors combined are designed to help melt the fat off of your body, so you can enjoy a leaner, harder, and healthier look. But will Instant Knockout Cut really help shred off the pounds, or is it just another run-of-the-mill fat loss supplement that doesn’t work? Read on to find out. 

Instant Knockout Cut Ingredients

Instant Knockout Cut comes in capsule form, and the recommended dosage is 1 capsule four times per day. Below is the ingredient label for four capsules serving:

instant knockout cut ingredients

Glucomannan

Up first is glucomannan, which is a dietary fiber found in the root of the konjac plant. When combined with water in the intestines, it forms a bulky fiber that can help suppress appetite, as well as slow the absorption of sugar and cholesterol. Recent reviews show that glucomannan supplementation is effective for decreasing weight and body fat in overweight and obese people. 

At least 1 gram is best, sometimes up to 4 grams or more. 

Green Tea Extract

Green tea and its main compounds, catechins, act as sympathetic nervous system stimulators, which can increase energy expenditure and promote fat oxidation. Plus, some research shows that green tea extract fat and carbohydrate metabolism. And overall, green tea extract supplementation appears to be effective in promoting fat loss and weight loss. 

Recommended dose is 250 to 500mg. 

Caffeine Anhydrous

Instant Knockout Cut also has the infamous caffeine, in a pretty high dose, for that matter. Caffeine is a very strong CNS stimulant and can also result in increased energy expenditure, fat oxidation, and thermogenesis. Plus, caffeine can increase mood and alertness through its actions on dopamine, norepinephrine, and other neurotransmitters. 

Plus, it can improve exercise performance, too, such as endurance, power, and strength in some cases. Overall, research shows caffeine is effective for reducing body weight, body fat, and BMI. If you are sensitive to this ingredient, though, there are fat burners out there, like Kaged Muscle Clean Burn, that do not include caffeine.

Generally, 100 to 300mg of caffeine is effective. 

L-Theanine

L-theanine could be considered caffeine’s partner in crime since it has a balancing effect on caffeine by promoting feelings of calmness and focus. It increases alpha waves in the brain, as well as serotonin, GABA, and dopamine, all for a mood boost and feelings of relaxation. And research shows combining caffeine with theanine leads to improvements in alertness, attention, and overall cognitive function

Most research uses 200mg per day. 

Cayenne Powder

Up next is cayenne powder, which comes from the cayenne pepper fruit. Cayenne is rich in capsaicinoids, which research shows can increase thermogenesis and metabolism, thus stimulating fat oxidation. 

Not only that, cayenne can improve insulin sensitivity, reduce blood glucose and cholesterol, decrease blood pressure, and reduce oxidative stress and inflammation, all of which play a role in weight loss and health. Overall, cayenne seems to be moderately effective for weight and fat loss. 

Black Pepper Extract

Black pepper extract is known to increase the bioavailability of many ingredients, so it can increase the effectiveness of the ingredients in here. Plus, black pepper has its own benefits of increasing thermogenesis and enhancing digestion. 

5 to 15mg is effective. 

Vitamin B6 and Vitamin B12

Instant Knockout Cut also has vitamin B6 and vitamin B12, which are two B-complex vitamins. Both of these are involved in energy metabolism, neurotransmitter synthesis, and other aspects of brain health, so they are important for mood and energy levels. The roles of B6 and B12 in fat metabolism also may play a small role in fat loss. 

Vitamin D3

The final ingredient is vitamin D3, which acts as a prohormone. Vitamin D is important for bone and muscle health, hormonal maintenance, immune health, and even brain function. Research also shows that low vitamin D levels are associated with higher fat mass, although supplementation doesn’t seem to be very beneficial for weight loss. 

Does Instant Knockout Cut Work?

Overall, Instant Knockout Cut should be a pretty effective fat loss supplement. It has all well-researched ingredients, such as caffeine, glucomannan, green tea extract, and cayenne, and they are all at optimal dosages, with the exception of theanine.

The ingredients in Instant Knockout Cut have been proven to increase thermogenesis, boost metabolism, and suppress appetite. Plus, Instant Knockout Cut should also be able to increase energy levels, boost exercise performance, and improve mood. 

Claims vs. Reality

Instant Knockout Cut should work, but it’s important to be realistic of your expectations. This supplement won’t magically melt the pounds off your body, but it should help you lose a few extra pounds over what you would lose with diet and exercise alone. 

And it should also give you a mild to moderate boost in energy, mood, and performance, which could help you lose more fat and enjoy the process a bit more along the way. 

Who is Instant Knockout Cut Best For?

Originally designed for high-level combat athletes, Instant Knockout Cut is best for any athlete who wants to lose fat and get into top-level shape more quickly than through traditional exercise and diet alone.
