I'm a 15 year old girl that weighs around 150lbs. I want to lose about 20 to 25 pounds. I drink about 4-5 glasses of water or green tea a day. I'm home schooled and don't have many friends, so I don't have many chances to go out. I go out and have walks every few days but it's not enough. I eat lots of fruits and vegetables as well. What are some ways to help lose weight?
