Does Green Tea Increase Metabolism?


In short, yes, green tea does cause an increase in metabolic rate. In a 2000 study from the department of physiology at the University of Geneva, researchers found that yes indeed, green tea extract, rich in catechin polyphenols is effective in increasing the body’s energy expenditure (and fat oxidation) for a 24 hour period.

The research involved subjects ingesting green tea at breakfast, lunch and dinner. Relative to the placebo, the green tea resulted in a thermogenic effect that promoted fat oxidation and a 24 hour increase in calorie expenditure.

Interestingly enough, the study also suggested that it wasn’t the caffeine that caused the effect. Treatment with equal amounts of strict caffeine in amounts equivalent to those found in the green tea had no noticable effect on metabolic rate.

    I’m a tea addict. I could never get through an entire day without a cup of freshly-brewed loose green tea. The smell alone is enough to make my mouth water and the delicious sensation of fresh hot tea sliding down my throat is something that I always take time to relish during my tea break. Green tea has tons of health benefits and is a great source of antioxidants. The ever increasing sale of green tea actually, is due to its ability to produce fat oxidation. This simply means that drinking green tea will act directly on your body to lessen your fats because of its natural oxidizing property.
