Furthermore, the high heterogeneity of the studies regarding study populations (healthy subjects and subjects with different comorbidities) may hinder the results strength. In 2010, EFSA examined health claims related to green tea and concluded that "a cause and effect relationship has not been established between the consumption of catechins (including EGCG) from green tea … and contribution to the maintenance or achievement of a normal body weight" . A meta-analysis of 11 randomized controlled trials found that people who took EGCG combined with caffeine for 12–13 weeks lost a mean of 1.31 kg more body weight (or gained 1.31 kg less weight) than those in control groups . The authors reported that green tea catechins combined with caffeine over a median of 12 weeks modestly yet significantly reduced body weight by a mean of 1.38 kg and waist circumference by a mean of 1.93 cm compared with caffeine alone . Thus, the activation by capsaicin of the same afferents may reduce the calorie intake by speeding the intestinal transport of food, and, at the same time, increase energy expenditure by lowering the body temperature. Thus, it will stimulate adiponectin secretion and increase body fat accumulation.
