SUMMARY
Obesity are defined as excessive fat accumulation caused of imbalance energy in and energy out. Consuming a cup of co?ee can help prevent obesity through chlorogenic acid compound. Chlorogenic acid is one of biactive component that has an important role to our body. Chlorogenic acid has a potential role in body weight reduction and preventing obesity. Chlorogenic acid has an e?ect to inhibit the absorption of glucose in the intestine, block the conversion of glucose to fat in the adipose tissue and protect from weight gain. Chlorogenic acid that contain in co?ee has a di?erences that depend on variety, type, roasting duration, temperature and co?ee bean size. Based on several studies, giving chlorogenic acid as a form of supplementation or green co?ee extract has demonstrated a consistent result. Those studies explain that chlorogenic acid in co?ee can inhibit body fat accumulation and reducing body weight. The aim of this systematical review was to know the contain of chlorogenic acid in co?ee and analyze the e?ect of giving chlorogenic acid to obesity. The experimental studies in human and animal subjects in the last 15 years as inclusion criteria and studies that is not represent the anthropometry result as exclusion criteria through electronic database were comprehensively reviewed. The result from five studies demonstrated that chlorogenic acid has an e?ect to reduce body weight, reduce body fat percentage, and reduce blood glucose concentration with the duration and chlorogenic acid dosage di?erently. Chlorogenic acid has many benefits in improving the obesity.
