Caffeine suppresses weight gain due to a diet rich in fat and sugar
During the year-end and New Year holidays, people often eat too much or lack exercise, but new research has shown that caffeine in coffee and tea can reduce fat accumulation. In a mouse study, individuals who continued to take caffeine had a lower rate of weight gain and body fat gain than those who did not.

The results of this study were derived from a mouse experiment by researchers at the University of Illinois. Researchers respond to micemate teaAfter giving it four weeks of caffeine,DecafThe mice gained 16% less body weight and had 22% less body fat when compared to mice fed mate tea. Yerba mate is a popular drink in South America, with phytonutrients (Fight Chemical) AndFlavonoid,amino acidContains many. The amount of caffeine per drink is 30-300mg per cup of hot coffee, while that of mate is 65-130mg.
During the experiment, the food given to mice consisted of 40% fat, 45% carbohydrates and 15% protein. Researchers performed similar experiments using coffee and synthetic caffeine in addition to mate tea, but the results were almost the same as with mate tea, indicating that the accumulation of body fat in mice was reduced. Was. The amount of caffeine taken by mice during the period was equivalent to "4 cups of coffee a day" when converted to humans.
To investigate this mechanism, researchers subsequently performed cell culture experiments in which fat cells taken from mice were exposed to synthetic caffeine and caffeine extracted from coffee and mate tea. The results showed that, regardless of the type of caffeine, lipid accumulation in adipocytes was reduced by 20-40% for all caffeine types.
In addition, scientists have identified multiple sources related to obesity and lipid metabolism.Gene expressionTraces that caffeineFatty acid synthase(Fasn)AndLipoprotein lipase(Lpl)Has been shown to reduce gene expression. Fasn is an enzyme used to synthesize fatty acids from glucose, and Lpl is responsible for encoding an enzyme that breaks down neutral fats. Researchers believe that suppressing the gene expression of these substances in the liver can reduce LDL cholesterol (bad cholesterol) and triglyceride production.
"This finding suggests that mate and caffeine may help antiobesity." "Studies understand the role of mate and caffeine as potential strategies to avoid overweight and obesity So it can be extended to humans, "said the researchers.
