IV. FINDINGS
The terms "green tea effects on obesity" in connection

to "integrative" and all of its synonyms, as well as "search
database," were used to conduct the systematic review
search. Through the Google search engine, manual Google
Scholar as well as PubMed searches were conducted. In the
database, 5 more articles were discovered. 1140 articles
were found in the initial search, 1060 of which were
eliminated for being irrelevant. 50 articles were eliminated
due to database replication after being carefully chosen from
80. Replication was eliminated, and the acceptability of 26
articles was examined. 18 further papers were disqualified
because the complete text was unavailable. Therefore, 5
articles, including an experimental investigation, were
screened.
V. DISCUSSION
This narrative review was supported by a randomized

placebo controlled double blind trial on body weight
reduction and weight maintenance in connection to habitual
caffeine intake and green tea supplementation by Westerterp
-PM S, Lejeunem P.G.M, and Kovacs E M. R. High caffeine
consumption has been linked to leptin suppression in
women and weight reduction through fat oxidation and
thermogenesis. The combination of green tea and caffeine
increased WM in regular low caffeine users, in part via
promoting thermogenesis and fat oxidation.
VI. CONCLUSION
Between the pre-test and post-test weight levels in the

experimental group, there was a significant change. The
green tea approach is efficient in reducing the
weight/obesity symptoms in the adult population and can be
used as a main treatment or adjuvant for medical treatment
of obesity diseases.
