The biggest problem I'm experiencing is severe stomach bloating. I jog on the treadmill 45 minutes five days a week. I was losing weight from that. Then I ordered Thrive after two months the daily bloating I've experienced has actually put 10 lbs on me. I swear to all my eating habits are great and with my workouts you would assume I'd continue to lose weight but the severe stomach bloating is horrible don't try this product
