What are the fundamental mechanisms by which tea consumption reduces body weight, alleviates metabolic syndrome, and prevents diabetes and cardiovascular diseases?
Mol Nutr Food Res · 2015 · PMID 26577614 · DOI 10.1002/mnfr.201500428
Tea's health benefits may stem from reducing nutrient absorption and activating a key metabolic enzyme, AMPK.
The question
What are the fundamental mechanisms by which tea consumption reduces body weight, alleviates metabolic syndrome, and prevents diabetes and cardiovascular diseases?
What they tested
The two major mechanisms for tea's beneficial effects are decreasing absorption of lipids and proteins in the intestine and activating AMP-activated protein kinase (AMPK) by tea polyphenols in the liver, skeletal muscle, and adipose tissues.
How they did it
This study is a review of existing literature, proposing mechanisms based on previously published research.
What they found
The proposed mechanisms are: (i) reduced absorption of lipids and proteins in the intestine by tea constituents, leading to decreased calorie intake; and (ii) activation of AMP-activated protein kinase by bioavailable tea polyphenols in the liver, skeletal muscle, and adipose tissues. Activated AMPK would decrease gluconeogenesis and fatty acid synthesis while increasing catabolism.
What it means
Tea's beneficial effects on body weight and metabolic syndrome are likely mediated by reduced lipid and protein absorption and activation of AMPK. The relative importance of these mechanisms may vary with tea type and diet.
Limitations
The study acknowledges that other mechanisms and the full health relevance of tea consumption's beneficial effects require further investigation.

For weight and metabolic syndrome, meta-analyses of randomized trials indicate that green tea catechins produce small, generally modest effects—limited reductions in body weight (on the order of 1 kg), body fat, waist circumference, total and LDL cholesterol, blood pressure, and fasting glucose—often more evident…
