Fat Metaboliser Review

How Fat Metaboliser Works

woman wondering how diet pill works 538

The information behind how Fat Metaboliser works is sparse, but a simple examination of the ingredients within the pills can help piece together the science behind the product. Essentially, these tablets work by increasing the metabolic rate in a process known as the thermogenic process. This means that the supplement, in theory, can cause the body to generate heat or energy. Fat Metaboliser pills supposedly works by accelerating body metabolic rate in order to burn more calories and burn fat thereafter.

The green tea contained inside the pills work by speeding up the body’s metabolism to obtain speedy results. Other ingredients include cayenne pepper, which contains capsicum, causing the body’s temperature to rise and consequently burn food more rapidly and efficiently. The addition of Vitamin B6 to the ingredients of the Fat Metaboliser pills suggests that there may be beneficial side effects from the tablets.

Key Fat Metaboliser Ingredients


Fat Metaboliser features Green Tea and Chromium, Cayenne and Vitamin B6. These are all natural ingredients and some of these are thought to assist with weight loss.

Green Tea

Green tea is derived from the leaves of Camellia sinesis. Frequently used as a beverage, green tea is thought to have many benefits such as, improving mental alertness, cancer prevention, gum disease and of course weight loss. However, evidence behind some of these claims is lacking. It is thought to assist weight loss via boosting the metabolism. It is the caffeine within green tea which enables it to act in such a way.


Chromium is a mineral. It can be found within the human body as well as in various food sources such as meats and potatoes. Chromium is thought to assist those with type 2 diabetes and some believe the mineral is also beneficial in keeping cholesterol levels low.


Cayenne pepper is often used in cooking to add heat to dishes. Cayenne is thought to assist with metabolism boosting and fat burning. It supposedly does this by inducing thermogenesis.

Vitamin B6

Vitamin B6 is thought to have many health benefits such as, acting as a treatment for anemia and preventing side effects in people taking cycloserine. There is little evidence to suggest that it is beneficial in regards to weight loss.

Clinical Studies

Clinical Researcher 538

Clinical trials are research studies that explore whether a medical strategy, treatment or device is safe and effective for humans. They are also used to show what medical approaches work best for certain illnesses. A lot of scientific research is done first before any clinical trial takes place, and then the next step is normally animal testing to see how the approach affects a living body, and if it could be potentially lethal. However, what does work well on animals in a laboratory environment wouldn’t necessarily work in the real world so that’s when tests on humans are needed.

Although no clinical studies have been conducted on Fat Metaboliser itself, there have been several conducted on the product’s ingredients.

Green Tea

A study carried out at the Department of Human Biology, Nutrition and Toxicology Research Institute at Maastricht University in the Netherlands discovered that drinking green tea can help a person significantly lose weight and maintain the lower weight once pounds have been lost. These healthy ingredients contributing to such successful weight loss may be discovered in all green teas.

A further study published by the Journal of Nutrition in their February 2009 edition concluded that consuming catechin, an ingredient discovered in green tea, led to higher levels of exercise-induced abdominal fat loss in overweight and obese adults. This was proven in how the triglycerides in the participants’ bloodstreams were also lower than those who did not drink green tea. Consequently, conclusions from this study presented how drinking green tea for weight loss can benefit an overweight or obese person when tea drinking is combined with regular diet and exercise. In fact, only when green tea is drunk and does not reflect any major fat loss results will only occur when a person continues to live a sedentary lifestyle, with too many calories per day. This study did, however, show that it could still help somebody to lose a few extra pounds from the body.

Cayenne pepper

An independent clinical study examined the effects of capaicinoids, which inclue thermogenic ingredients including cayenne pepper. The progress of this study is examined: Clinical Study 3: Capaicinoids and Red Pepper Human Studies Review. This study was produced in order to test the capaicinoid ingredients held within the Meratol tablets. This clinical study reflected how carbohydrate oxidation was significantly higher and lipid oxidation significantly lower in the red hot pepper diet than in the control diet. These findings reflected how red pepper increases both diet induced themogenesis and lipid oxidation, proving excellent for faster metabolism and fat burning.
