This paper reviews provenance, chemical composition and properties of tea (Camelia sinensis L.) and coffee (Coffee arabica, L. and Coffeacaniphora, L.), their general health effects, as well as the currently available knowledge concerning their action on fat storage, physiological mechanisms of their effects, as well as their safety and recommended dosage for treatment of obesity. Both tea and coffee possess the ability to promote health and to prevent, to mitigate and to treat numerous disorders. This ability can be partially due to presence of caffeine in both plants. Further physiological and medicinal effects could be explained by other molecules (theaflavins, catechins, their metabolites and polyphenols in tea and polyphenol chlorogenic acid in coffee). These plants and plant molecules can be efficient for prevention and treatment of numerous metabolic disorders including metabolic syndrome, cardiovascular diseases, type 2 diabetes and obesity. Both plants and their constituents can reduce fat storage through suppression of adipocyte functions, and support of gut microbiota. In addition, tea can prevent obesity via reduction of appetite, food consumption and food absorption in gastrointestinal system and through the changes in fat metabolism.
本文综述了茶（Camellia sinensis L.）和咖啡（Arabica coffee 和 Canephora coffee）的起源、化学成分和性质，它们的一般健康影响，以及目前关于它们对脂肪储存的作用、作用的生理机制，以及它们在肥胖治疗中的安全性和推荐剂量的相关知识。茶和咖啡都具有促进健康、预防、减轻和治疗多种疾病的能力。这种能力部分可能是由于这两种植物中都含有咖啡因。其他分子（茶中的茶黄素、儿茶素、它们的代谢物和多酚，以及咖啡中的多酚绿原酸）也可以解释它们的其他生理和药用作用。这些植物和植物分子可有效预防和治疗多种代谢紊乱，包括代谢综合征、心血管疾病、2 型糖尿病和肥胖症。这两种植物及其成分都可以通过抑制脂肪细胞的功能和支持肠道微生物群来减少脂肪储存。此外，茶可以通过减少胃肠道系统中食欲、食物消耗和食物吸收，以及改变脂肪代谢来预防肥胖。
