    I just recently started taking green tea extract 400 mg of liquid soft-gel. I have rapidly gained approx. 15 lbs. in about 4-5 weeks I am a thin build by nature and had about 8 lbs. I wanted to drop., however since taking the capsules I have gained an additional 7 lbs. Is there any reason the green tea could be the cause.
