Matcha increases fat oxidation, reduces carbohydrate oxidation during moderate physical activity
Matcha is a green tea variant which is gaining popularity. A few cups of Matcha per day can ensure that you burn a little more fat during moderate-intensity physical activity instead of carbohydrates. Sports scientists at the University of Chichester write this in the International Journal of Sports Nutrition and Exercise Metabolism. This shift may be interesting, especially for athletes, but perhaps also for people who want to lose weight.
Study
The researchers got 13 women on two different occasions to walk for 30 minutes on a treadmill with a brisk pace of 5.8 kilometers per hour. On one occasion, the women were given a placebo before they exercised [control]; on the other occasion they drank 4 cups of Matcha tea [matcha].
Matcha is mad from tea plants that grow in the shade and therefore produce more chlorophyll. After picking and drying the leaves, the tea is ground into a powder. If you drink Matcha, you drink hot water and powder. Match tea contains more bioactive compounds like EGCG than green tea that's brewed from leaves. The researchers used Matcha from the British OMGTea. [omgteas.co.uk]
On the day before the test, the subjects drank 3 cups of Matcha. Each cup contained 1 gram of Matcha powder. On the day of the test, 2 hours before they stood on the treadmill, the women drank another cup.
Results
Supplementation with Matcha did not affect the total amount of calories the women burnt while exercising, but it did change the type of fuel they burnt during exercise. Matcha made them burn a little less carbohydrates, and a little more fat.
Conclusion
"Matcha green tea drinking, just 4 cups in 24 hours enhanced fat oxidation during brisk walking in healthy females", the researchers summarize.
"The composition of Matcha green tea leaves is sufficient for habitual Matcha drinking to provide beneficial metabolic responses during brisk walking. However, when regular moderate intensity exercise is undertaken as part of a weight loss program, the effects of Matcha should not be overstated."
