The benefits of green tea are beyond reproach. It is one of the most studied herbs in the world. Recently a study was published in HerbalGram of the American Botanical Council .
We know that Green tea (Camellia sinensis, Theaceae) supplementation can positively affect energy and hormone balance. Green tea contains catechins which have been shown to increase fat oxidation and have anti-obesity effects. In a meta-analysis, green tea improved lipid and glucose metabolism. The authors conducted a randomized, double-blind, placebo-controlled trial to evaluate the effects of a 60-day dietary supplementation with green tea extract on adipose tissue dysfunction in overweight or class I obese post-menopausal sedentary women.
The authors conclude green tea has significant benefits for lipolysis pathway in women that are post menopause. Green tea was shown to decrease weight and body fat markers. One strength of this study was that the authors analyzed a variety of factors that can determine weight loss and change in body composition. Limitations included not measuring urinary nitrogen excretion, not being able to calculate protein oxidation, using a specific population of overweight and obese individuals, and having a small number of participants. Further research with different populations of individuals and a larger number of participants is needed to verify these results It was also a very small study group 14 participants in each arm of the study The study was originally published in
