Each one of us has a different body types and react differently on diet pills. Some easily loss weight on diet pills but some needs to take it longer and combine it with exercise to achieve good result. If a certain diet pills works on me that doesn't mean that this will work the same way to my friends too.
One of my friend have a problem with diet supplement, her body reacts differently. I suggest to her that she needs to read the reviews of the best weight loss pills online and find the best one that matches her needs. After couple weeks she called me to inform that she lost 10 pounds and she found the best weight loss pills for her on the online review site.
