“…The reduction in BW ranged from 0.7 kg (Auvichayapat et al, 2008) to 3.5 kg (Chantre and Lairon, 2002), and the loss in body fat ranged from 0.7 kg (Nagao et al, 2005) to 1.8 kg (Nagao et al, 2007). The dosage of EGCG used in the aforementioned investigations ranged from 100 mg/d (Nagao et al, 2007) to 540 mg/d (Chan et al, 2006). In the 26 human experiments conducted by Hursel et al (2011) and Phung et al (2010), most of the investigations discovered that tea drinking could reduce BW.…”

“…The optimal EGCG dose to increase fat oxidation and support a weight management has not yet been established. The dosage of EGCG used in those studies ranged from 100 (Nagao et al, 2007) to 540 mg/d (Chan et al, 2006), while the duration of the studies varied from 1 d (Komatsu, 2003;Bérubé-Parent et al, 2005) to 13 weeks (Kovacs et al, 2004).…”

“…azalma olduğu, ancak düşük enerjili diyet alan plasebo grubu ile karşılaştırıldığında vücut ağırlığı ve kompozisyonlarında istatistiksel olarak anlamlı fark olmadığı tespit edilmiştir (57). Polikistik over sendromu olan 34 obez kadın ile yapılan bir çalışmada da, 3 ay sonrasında yeşil çay tüketen grubunun vücut ağırlığında %2.4 oranında azalma olduğu, ancak kontrol grubu ile karşılaştırıldığında bu durumun anlamlı olmadığı saptanmıştır (58). Aşırı kilolu ve meme kanseri olan 39 kadın ile yapılan randomize kontrollü bir çalışmada da, 6 ay sonrasında günde 960ml yeşil çay tüketen bireylerin vücut ağırlığında 1.2kg azalma olduğu, plasebo grubunda ise 0.2kg azalma olduğu, ancak bu farkın istatistiksel olarak anlamlı olmadığı belirlenmiştir (37).…”

ÖZETSağlığı bozacak şekilde vücutta anormal ya da aşırı yağ birikimi olarak tanımlanan obezite dünya genelinde hızla artan önemli bir halk sağlığı sorunu olup, kadınlarda erkeklere oranla daha sık görülmektedir. Son yıllarda, obezite ile mücadele için kullanılan yöntemlerden biri doğal bitkisel ürünlerin kullanımıdır. Yapılan epidemiyolojik ve klinik çalışmalarda, çayın içeriğinde yer alan kimyasal maddelerin sağlık açısından olumlu etkileri ile obezitenin önlenmesinde ve tedavisinde yarar sağladığı gösterilmiştir. obez kadınlar ile yapılan üç aydan daha uzun süreli çalışmaların çoğunda da, özellikle yeşil çayın kilo vermeye katkı sağladığı belirtilmiştir. Ancak yapılan kontrollü müdahale çalışmalarının yetersizliği ve çalışma tasarımlarının karışık olması, obez kadınlarda çay tüketiminin etkinliğine yönelik daha fazla çalışma gereksinimini ortaya koymaktadır. mevcut derlemede, kadınlarda obezite ile baş etme ve obeziteyi önlemede çay tüketiminin etkinliği literatür doğrultusunda tartışılmıştır. Kanıta dayalı verilerin sunulduğu bu derlemenin, obeziteyi önlemede sağlık profesyonellerine yön gösterici olacağı öngörülmektedir.Anahtar Kelimeler: Çay; sağlık; obezite; kadın. ABSTRACTDefined as the unhealthy abnormal or excessive accumulation of fat in the body, obesity is an increasingly important public health problem around the world and has a higher incidence among women than among men. In recent years, one of the fastest growing fields in the treatment of obesity is the use of natural herbal products, among which tea stands out as a prominent element. Relevant epidemiological and clinical studies showed that the positive effects of chemical substances in tea on health provided benefits in the specific prevention and treatment of obesity. Most of the studies conducted with obese women over a course of more than three months reported that especially green tea contributed positively to weight loss. However, the insufficient number of controlled intervention studies and the complex nature of the designs of existing studies point out to the need for further studies on the effectiveness of tea consumption among obese women. Thus, this review discusses the effectiveness of tea consumption in coping with and preventing obesity among women in line with the existing literature. Providing evidence-based data, this review is considered to be a prospective source of guidance for healthcare professionals for the prevention of obesity.

“…Chantre and Lairon (2002) reported a 4.6% weight loss over 12 weeks in an open-label study, 2002), but a placebo-controlled study of green tea extract in subjects with polycystic ovarian disease gave a 2.4% weight loss over 3 months that was not significantly greater than the loss with placebo, and there were no improvements in glucose or lipid metabolism (Chan et al, 2006). Kovacs et al (2004) found that green tea extract was no better than placebo in maintaining a 7.5% weight loss over 13 weeks.…”
