hi lisa,
i certainly agree with you here. we should not be taking drugs that stimulate our metabolism. rather we should be eating foods that allow our metabolisms to function in the way that they were designed.
our hormones, early on, made the number of fat cells that our bodies have, which today regulates the amount of body fat we will have. if we are eating correctly, thusly performing as designed, our bodies will oscillate about that body fat percentage in which it was designed to have.
the goal of nutrition is "allowing our bodies to function as they were designed", not about how we look in the mirror.
