The study led by Cao Z. H. and colleagues from Yunnan Agricultural University in Kunming, China tested Pu-erh tea in male Sprague-Dawley rats that were fed a high fat diet for its antiobesity and antihyperlipidaemic effects.

In the study, the rats were randomly fed a control diet, high fat diet, high fat diet supplemented with low, moderate or high doses of pu-erh tea extract (0.5 grams, 2 grams and 4 grams per kg of body weight per day).

The researchers found Pu-erh tea significantly reduced the total body weight and the weight of various adipose pads.

In addition, the tea extract also significantly lowered serum cholesterol, triglycerides and low-density lipoprotein-cholesterol in rats with obesity induced by the high fat diet.

The reduced accumulation of lipid or fat may be due to the fact that Pu-erh tea extract boosted the enzymatic activities of a number of lipases including lipoprotein lipase, hepatic lipase, and hormone-sensitive lipase in the rats with obesity induced by high fat diet.

At least, the increase in the activity of hormone sensitive lipase is due to the fact that Pu-erh tea extract enhanced the transcription of mRNA of the enzyme.

The results reported in the July 16, 2010 issue of Phytotherapy research : PTR suggest that drinking Pu-erh tea may help fight obesity induced by a high fat diet and improve hyperlipidemia.

Pu-er tea is a type of tea made from a "large leaf" variety of the tea plant Camellia sinensis and named after Pu'er county near Simao, Yunnan, China.
