What is known about obesity Obesity occurs for many reasons, including heredity, poor nutrition, hormonal problems and the environment (inactivity). For this reason, after obesity or overweight, people decide to return to their previous ideal weight by using fat-burning supplements. Primarily, green tea has been ranked as a fat burner and supplement for many years. Of course, it is not possible to use sports supplements without doing sports activities. For this reason, the use of sports supplements along with sports activities with appropriate intensity and duration can cause very significant changes in body composition. There are many fat burning supplements that have a long-term negative effect on the body due to their chemical nature. For this reason, obese people are looking for natural fat burning supplements. In recent years, plants have been able to have significant effects on fat oxidation. Meanwhile, tea after water is one of the most widely consumed natural plants in the market, which has very few negative effects. Tea consumption in the world is typically 120 ml per day. The mechanisms of action of tea in relation to obesity include: increased hepatic metabolism, caffeine synergy, decreased appetite, exothermic stimulation and increased enzymes associated with fat burning .Among teas, green tea is one of the most popular natural herbal supplements in fat burning that most people around the world use this tea to increase fat oxidation. The main ingredients of most teas are epicatechin, epigallocatechin, epicatechin gallate and epigallocatechin gallate. There are four main types of tea that are produced depending on the type of processing, which include green, white, black and oolong tea. Studies have shown that oolong tea and black tea can both increase fat oxidation in obese and overweight people. But this fat burning effect is less than green tea. For this reason, extensive research has been done on green tea and its effect on fat oxidation, and researchers have been able to conclusively report that this tea can be a beneficial fat supplement. Meanwhile, several studies have been able to prove that white tea has more fat-burning substances than green tea. For this reason, it is possible that white tea is much more useful than most fat-burning teas. The naming of white tea by this name is due to the white silver villi of the immature buds of the tea plant, which gives it a white appearance, although its brew is pale yellow. In very limited research on laboratory mice, researchers have reported that white tea affects adipose tissue lipolysis. But so far, no research has been done on humans that in Iran for the first time the effect of white tea on fat oxidation in obese people was discussed. In this study, subjects poured 10 grams of white tea in 500 ml of boiling water and brewed it one hour before exercise. Finally, the researchers reported that consuming white tea one hour before exercise could increase fat oxidation in obese people. Therefore, according to the only current research on humans and similar animal research, this study examines the effects and compounds of white tea. In this review study, articles with the keyword’s green tea, obesity, green tea and fat oxidation, green tea compounds, effects of green tea compounds, white tea, white tea and fat oxidation, white tea and weight loss, white tea compounds were selected. 120 articles related to the present study were found. Then, out of 120 articles, 43 articles did not correspond to the present study, so they were removed from the study. Finally, 77 articles in this review study were discussed by researchers. Discussion: Obesity is on the rise and the search for a beneficial supplement to improve fat oxidation is becoming increasingly important. The present study showed that tea can be prescribed as a plant and a healthy beverage for obese people to reduce body fat percentage. Also, in this specialized study, it was found that the ingredients of white tea are the same as green tea, with the difference that in some compounds, the amount of substances that affect fat oxidation is higher. This factor may raise the question of whether white tea can be superior to fat tea and other teas in fat oxidation. The necessity of this study is that due to the unfamiliarity of white tea and the anonymity of its ingredients, by doing this study, a new way will be opened for future researchers and researchers will show significant results with initial studies. Researchers can compare the effects of green and white tea on fat oxidation in both the short and long term to provide the results of this valuable tea. It is also possible to study the effects of this tea compared to other fat burners such as caffeine or other supplements at different times such as morning and evening and determine the best time to consume it. The strength of this review study was that it was able to first examine the importance of green tea through short-term and long-term research tables and then focus on past research on white tea, breaking down the ingredients of this tea. One of the weaknesses of this article was that due to the extensive search; The authors were able to find very little research on white tea. For this reason, it cannot be said with certainty that white tea can be 100% superior to green tea. But based on the study of its ingredients, it can be concluded that it can probably be superior to other teas in fat oxidation. Finally, this study states that white tea as a natural fat burner can be useful in the process of fat oxidation. But the consumption of this tea should be influenced by exercise in order to have significant effects on fat oxidation. Long-term exercise and consumption of green tea could play an important role in increasing oxidation. It is therefore probable; White tea can be used in long-term sports activities and have better effects. Therefore, these results can play a decisive role in directing future selective strategies to improve body composition and weight loss
