A green tea weight loss study featured in the American Journal of Clinical Nutrition state that green tea extracts produce significant increases in spent energy--how metabolism is measured--as well as a dramatic effect on oxidations of fat. While some of these effects were initially thought to be caused by the caffeine found in green tea, researchers have discovered that green tea actually contains certain properties that extend beyond what was explained by caffeine. Same amounts of caffeine, as found in green tea, were administered alone. The administered caffeine failed to cause any changes in energy expenditures. This has led researchers to theorize that some form of interaction is happening with green tea's active ingredients that is the cause of the increase in fat oxidation and metabolism.

The researchers of the same green tea weight loss study said that the results of their study pose substantial implications for use in weight control. For a 24-hour period, an overall increase of 4% was attributed to extracts from green teas although it was also noted that the increase in expenditure happened during the day. This led the researchers to the conclusion that spent energy in a subject, with the 4% increase in overall energy expenditures, actually produced a 35% to 43% increase in thermogenesis during the day. Research subjects also didn't report side effects and differences with heart rates were barely noticeable. Because of this, green tea then is different from other prescription obesity drugs and other herbal products.

In another green tea weight loss study at the University of Geneva, researchers have come to the conclusion that green tea does have thermogenic properties and is capable of increasing fat oxidation. This particular green tea weight loss study feels that these results are caused by other substances apart from what caffeine had caused. This conclusion differs from other studies that discount other substances found in green tea and attribute benefits for weight loss solely to green tea's caffeine content.

Results of another green tea weight loss study on the extract AR25 (Exolise) done by D. Lairon and P. Chantre in Laboratories Arkipharma in France show that the AR25 extract does help treat obesity. For the study, they made use of extracts from green tea (standard 25% catechins) in 80% ethanolic concentrate. Results of the green tea weight loss study reveal that green tea inhibits pancreatic and gastric lipases directly. Because these enzymes cause fat storage, delaying actions that they produce meant that green tea was a possible solution in treating obesity and weight loss problems.

Yet another green tea weight loss study, this time at the University of Chicago, prove green teas effects in weight reduction. Rats given extracts from green tea experienced loss of appetite and after seven days of treatment, consumed as much as 60% less of their food. The whole study caused the rats to lose as much as 21% off of their weight. The researchers also attribute it to green tea's regulating effects on blood sugar.

Studies have proven it - green tea can help you lose weight. Whether as tea or as a supplement, taking in green tea can help speed up your weight loss goals by complementing your fitness regimen. While green tea is all-natural and has not been known to cause any side effects, it is best to consult your doctor before taking it if you are suffering from any health condition or are currently taking in any prescription medication. This is to ensure that green tea does not cause further complications to your health.
