Introduction: No study compared the effectiveness of the green tea, fiber, caffeine and L-carnitine on weight loss in individuals. Therefore, the aim of this study was to evaluate the efficacy of green tea, fiber, caffeine and L-carnitine in clinical aspects of people. Materials and Methods: The databases of Pubmed, Scopus and Cochran were searched up to November 2018. The pairwise method was used to compare the difference between the mean weight loss of drugs in two direct methods (comparison of drugs with the control group) and non-direct (Compare medications together). Results: The present study performed on 73 clinical studies with a cumulative population of 3921, showed that caffeine (-0.88 kg; -2.60 to -0.84), caffeine + catechine (-0.74 kg; -1.70 to 0.21), green tea (-0.61 kg; -1.33 to -0.11), fiber (-0.31 kg; -0.79 to -0.17), respectively, had the most effect on weight loss compared with the placebo group. In addition, carnitine supplementation did not effect on weight loss. Conclusion: The present study indicated that green tea supplementation had a lower effect on weight loss compared with caffeine and caffeine+catechin, and had a greater effect on weight loss compared with fiber and carnitine.

Abstract: So far, no study has ever surveyed the effectiveness of injectable and oral forms of the Glucosamine compared with chondroitin sulfate and hyaluronic acid on physical function and pain in osteoarthritic patients. The aim of this study is to evaluate the clinical efficacy of glucosamine compared with chondroitin sulfate and hyaluronic acid in relieving pain and function of people with osteoarthritis.Design: The databases of PubMed, Scopus, Google Scholar and Cochran were searched up to November 2018. The pairwise method was used to compare the difference between the mean score of the evaluation forms before and after the intervention in two methods including direct (comparison of drugs with the control group) and non-direct (comparison of drugs with each other).Results: The present study showed that improvement in the performance of patients with osteoarthritis according to the WOMAC score, was the highest with oral form of chondroitin sulfate and then the injectable form of chondroitin sulfate and injectable form of glucosamine. Pain evaluation of patients showed the most pain reduction in the injectable form of hyaluronic acid and then the oral form of chondroitin sulfate. Pain assessment via the VAS form, showed that oral form of glucosamine alleviated the pain.Conclusions: This study demonstrated that, intake of oral form of chondroitin sulfate had the most effect on improving the physical function. Also, in the assessment of pain using WOMAC and VAS forms, the injectable form of hyaluronic acid and oral form glucosamine showed the highest improvement compared to other drugs.
