You may be surprised to know that I, a medical doctor,
do believe that there are certain herbs that help with weight loss. I am very
certain of this. Even though the medical establishment is quite skeptical, if
doctors learned more about these weight loss herbs and actually used them in
their practice, they would soon find out that these herbs are quite effective. There is
no doubt in my mind.
