Best Fat Burner Ingredients

FACT: Only a handful of fat burning nutrients on the market have the evidence to support them.

Fat burners and diet pills are confusing. There’s a lot of marketing and not a lot of facts. If you want to know what you should be looking for in a fat burner, this is the page you need to read.

When it comes to fat burners, they typically serve one (or more) of three functions:

  • Thermogenesis – This is a process that occurs in the body when it needs to regulate itself. This burns calories and requires no conscious effort occur – if you take the right nutrients to activate it.
  • Boost Energy – Mainly by using natural stimulants, fat burners use nutrients to boost your energy levels to keep you going for longer when on a low calorie diet.
  • Appetite Suppression – If you’re struggling to keep on top of your diet, you’ll benefit from these nutrients. By various methods they reduce your hunger cravings and keep you on top of your diet.

FACT: It’s rare to find a fat burner that performs all 3 of these functions at once – but they are out there.

The Highest Rated Fat Burning Ingredients

From reading clinical studies and from the feedback of our readers, we finally have the shortlist of what ingredients you should be looking for in a fat burner.

To make it onto our list these nutrients have to be:

  • Natural
  • Safe
  • Effective
  • Clinically Proven

These are the best ingredients for any fat burner:

Green Tea


  • Thermogenic
  • Increases Metabolism
  • Energy Booster
  • Antioxidant

Green Tea arguably one of the best fat burning ingredients on the market.

A big part of this is to do with the catechins in this herb. After being absorbed by your body, the catechins in the green tea release norepinephrine – the fat burning hormone.

With more norepinephrine, you’ll burn more calories than normal and burn more fat.

It’s also caffeinated so you’ll get an energy boost from it too.

Examples of Effectiveness

One 90 day study reported that subjects that used green tea daily lost an average of 1.2kg of weight.

Whereas this study has shown that one cup of Green Tea burns on average 5.7g of fat per cup.

Green Coffee Beangree-coffee-bean-fat-loss

  • Thermogenic
  • Increases Energy

Green Coffee is one of the better fat burning ingredients out there.

What makes Green Coffee Beans great is the nutrient’s natural chlorogenic acid. After being absorbed by the body, this chlorogenic acid helps cut down the glucose in your liver.

Glucose is the liver’s primary energy source, and without it, your body has to move onto other options – like fat.

Not only does this help you burn extra fat, it gives you an energy boost in the process.

Examples of Effectiveness

study that involved two groups of overweight subjects, saw great results for Green Coffee Bean.

The first group drank Green Coffee Bean every day for 12 weeks, while the other used instant coffee. The results were remarkable – the Green Coffee group lost a staggering 5.4kg.

Cayenne Pepper


  • Thermogenic
  • Suppresses Appetite
  • Supports digestion

Cayenne is a powerful chili and an effective fat loss aid.

This is all down to the capsaicin, this is what gives the chili its heat. After being absorbed, the heat from this nutrient raises your core body temperature.

With a higher temperature, your body starts to regulate itself and cool down. This process burns a lot of calories, and you don’t have to move a muscle to make it happen – it’s all down to the chili!

Examples of Effectiveness

Studies have shown that the capsaicin in cayenne pepper has been linked numerous times to thermogenesis and fat loss.

  • Increases Energy
  • Boosts Metabolism
  • Enhances Power Output and Stamina

When it comes to stimulants, there is no natural option better than caffeine.

After being absorbed caffeine suppresses adenosine in the brain, which is the sleep promoting hormone. This allows you stay fully awake and more active for much longer throughout the day.

Caffeine also promotes metabolism and power output in the body, which is ideal for both burning extra calories and training hard in the gym.

Examples of Effectiveness

Many studies have confirmed caffeine as an effective fat burner and metabolism booster.

While other studies have vouched for their effectiveness when it comes to power output.



  • Suppresses Appetite

Glucomannan is a specialist appetite suppressant.

Originally used in Japanese cooking, Glucomannan is fiber-rich nutrient that swells in the stomach after being consumed.

This makes you feel more full than would usually, and is great for staving off a demanding appetite while cutting weight.

Examples of Effectiveness

An impressive result from a Glucomannan study showed significant weight loss when the nutrient was taken over an 8 week period.

The subjects did not change their diets or exercise regimes and noticed a huge reduction in their waistlines.



  • Increases Nutrient Absorption

Essentially black pepper, but it’s not to be underestimated. This can make all the difference to your fat burner.

By inhibiting enzymes that would usually attack incoming nutrients, piperine allows more of your fat burner to be absorbed which delivers faster results.

Examples of Effectiveness

In one study, piperine was seen to improve the bio-availability of the nutrient curcumin by 2000%.

It is the ultimate nutrient to get the most out of your fat burner.
