Changes in FOX did not reach the level of statistical significance .
Finding showed that EGCG intake moderately accelerates EE and reduces RQ .
The analyses revealed that the EGCG result ed in difference in RQ and EE but the effect on the other measures of energy metabolism was relatively mild .
Possibly , EGCG alone has the potential to increase metabolic rate at 300 mg dose .
Collectively , the outcome supports the findings that EGCG has an effect on metabolic parameters .
Green tea catechins ( GTCs ) are known to improve fat oxidation ( FOX ) during fasted , rested and exercise conditions wherein epigallocatechin-3-gallate ( EGCG ) is thought to be the most pharmacologically active and has been studied extensively .
From the available data of r and omized controlled trials ( RCTs ) on EGCG , we carried out a systematic review and meta- analysis to eluci date whether EGCG consumption indeed increase energy expenditure ( EE ) and promote FOX .
Green tea extract reduces blood pressure, inflammatory biomarkers, and oxidative stress and improves parameters associated with insulin resistance in obese, hypertensive patients.
Green tea ( GT ) consumption is known to be associated with enhanced cardiovascular and metabolic health . The purpose of this study is to examine the hypothesis that supplementation with GT alters insulin resistance and associated cardiovascular risk factors in obese , hypertensive patients . In a double-blind , placebo-controlled trial , 56 obese , hypertensive subjects were r and omized to receive a daily supplement of 1 capsule that contained either 379 mg of GT extract ( GTE ) or a matching placebo , for 3 months . At baseline and after 3 months of treatment , the anthropometric parameters , blood pressure , plasma lipid levels , glucose levels , creatinine levels , tumor necrosis factor α levels , C-reactive protein levels , total antioxidant status , and insulin levels were assessed . Insulin resistance was evaluated according to the homeostasis model assessment -insulin resistance protocol . After 3 months of supplementation , both systolic and diastolic blood pressures had significantly decreased in the GTE group as compared with the placebo group ( P < .01 ) . Considerable ( P < .01 ) reductions in fasting serum glucose and insulin levels and insulin resistance were observed in the GTE group when compared with the placebo group . Serum tumor necrosis factor α and C-reactive protein were significantly lower , whereas total antioxidant status increased in the GTE group compared with the placebo ( P < .05 ) . Supplementation also contributed to significant ( P < .05 ) decreases in the total and low-density lipoprotein cholesterol and triglycerides , but an increase in high-density lipoprotein cholesterol . In conclusion , daily supplementation with 379 mg of GTE favorably influences blood pressure , insulin resistance , inflammation and oxidative stress , and lipid profile in patients with obesity-related hypertension
