if you are tying to lose weight the only way to really do it is to eat veggies and whole wheat grains and lean meat. Is there a reason you dont eat them yourself? because a vitamin wont replace the nutrition you get from those foods.

Where in this wide world can man find nobility without pride,
Friendship without envy,
Or beauty without vanity?
Here, where grace is served with muscle
And strength by gentleness confined
He serves without servility; he has fought without enmity.
There is nothing so powerful, nothing less violent.
There is nothing so quick, nothing more patient.
~Ronald Duncan, "The Horse," 1954
