How Green Tea Assists Weight Loss
Although the level involved is not particularly high, it is worth mentioning green tea is a source of caffeine. The fact that caffeine can be so useful for fighting off sleep, improving concentration, and boosting energy levels often means its other abilities are overlooked and many people fail to realize it is a mild appetite suppressant and a proven thermogenic fat burner.
However, as already stated, the caffeine content of green tea is minimal. Its real power for weight loss comes courtesy of certain antioxidants called catechins and, especially, epigallocatechin gallate (EGCG ). The EGCG provided by green tea assists weight loss by inhibiting the the actions of an enzyme that the breaks down an important hormone called norepinephrine that allow the nervous system to relay a signal to the fat cells that encourages them to break down fat. The fat is then released into the bloodstream, where it can by utilized as a source of energy.
A Few Cups of Green Tea Can Aid the Health in Many Ways
The fat burning abilities of green tea have been proven time and time again.
Researchers in Geneva conducted a study called Efficacy of a green tea extract rich in catechin polyphenols and caffeine in increasing 24-hour energy expenditure and fat oxidation in humans. The results confirmed green tea's fat burning potential cannot be explained by its caffeine content alone.
The fat burning abilities of EGCG are further confirmed by a study carried out by researchers at the University of Medicine in Berlin (Germany), who conducted a randomized double blind, placebo-controlled, cross-over pilot study involving six overweight men who were supplemented with 300 mg of EGCG every 24-hours for a two day period. Examination of the resultant data caused the researchers to conclude: "These findings suggest that EGCG alone has the potential to increase fat oxidation in men and may thereby contribute to the anti-obesity effects of green tea."
It's important to note that green tea extract is potent and can be dangerous for some people, specifically causing liver toxicity. One study mentions a growing number of toxicity reports, as the extract grows in popularity. It is important to let your doctor know if you want to use green tea extract so your dosage and response can be monitored.
For the purposes of another study conducted at the University of Birmingham (England), researchers recruited a group of healthy young men and monitored their glucose tolerance and fat oxidation during moderate intensity exercise. The resultant data showed the average fat oxidation rate of the green tea group was 17% higher than that of the placebo group.
Exercise always encourages extra energy expenditure, but the results of another study, conducted in Japan, suggest green tea can also encourage fat burning during periods of rest.
The results of a study conducted by a research team in Thailand also supports the fat burning abilities of green tea. The study had a duration of three months and involved a group of 60 obese people. The volunteers who supplemented with green tea burned an extra 183 calories per day.
Taking a Sensible Approach to Weight Loss
Although green tea has proven fat busting abilities, anyone who starts drinking green tea in the hope that it will help them to lose weight while still overindulging will be sadly disappointed.
Using the research conducted in Thailand as an example, the volunteers were only eating three meals per day, that provided at total of just over 2,500 calories per day. The average man would need this amount of calories to maintain his normal weight. The test subjects lost weight because the green tea caused them to burn extra calories, so their diet did not provide enough calories per day. When such a calorie deficit occurs the body is forced to begin burning its fat. Losing weight requires commitment though. If any of the test subjects had visited their local McDonald’s things would have been very different. A single Big Mac contains 540 calories. A standard portion of McDonald’s fries would provide another 230 calories. The fries alone may have provided enough calories to cause weight gain. So although green tea has proven value as a weight loss provider, it will not work miracles. A commitment to healthy living will still be required.
