TrimSpa works, but you have to add some sort of physical activity along with taking the pills. Even if you add a 30 minute workout video every other day, that will double the time and pounds you lose. You can still eat, but don't overeat. That will counter the effect of the pills. The side effects were mild headaches and frequent trips to the bathroom. I felt like I was pregnant and had to use the restroom every hour. I lost 10 pounds in 2-3 months time.
