Several studies have suggested that the flavonoids and caffeine in green tea can help elevate metabolic rate, increase fat oxidation and even improve insulin activity. One study showed that those who consumed green tea and caffeine lost an average of 2.9 pounds during a 12-week period, while sticking to their regular diet. Another study suggested the increase in calorie output was equal to about 100 calories over a 24-hour period. Consuming green tea in addition to several other healthy behavior modifications like consuming a healthy balanced diet with regular daily exercise will yield the best results.
What makes green tea an effective ingredient to burn fat?
One of the key compounds in green tea is Epigallocatechin gallate, or EGCG, a potent antioxidant thought of by some as a sort of kryptonite to body fat. Supporters say it reduces fat gain and enhances fat burning. But the amount found in a typical cup of green tea is not enough to have much effect; the amount of EGCG needed to have any affect is over 5 cups per day. That was made clear in a report published this month in The Cochrane Database of Systematic Reviews.
Can green tea be harmful if taken in excess?
You don’t need excessive amounts of green tea to see results, as little as 2 and half cups per day can yield some results. Drinking more then 5 cups towards the later hours of the day could affect sleep quality. Tea is not as strong as coffee but the caffeine still has stimulants effects.
Pros and Cons of taking supplements with green tea? Side effects? Supplements are all very different, if the supplement contains green tea and no other stimulants it is probably safer then the supplements that contain more powerful and potent stimulants. Do your research on the supplement’s claims and the company’s integrity. Green tea will not give you a surge of energy, but it will help sustain a steady energy level throughout the day.
Possibility to achieve weight loss results?
Green tea by itself will not have great success in weight loss efforts. Combining green tea with regular exercise, a healthy balanced diet rich in quality protein, vegetables, some low sugar fruits, and heart healthy fats will help with weight loss efforts.
