Bioelectrical impedance scales now are available for the home, said Kohlstadt, who also said proper hydration is another key to losing fat rather than muscle.
If we are what we eat, then many Americans are a junked car sitting up on blocks because of a diet rich in trans fats, refined sugar and other processed food, along with inactivity.

"We want to inspire people to make healthy choices ... and be able to live life to the fullest," said Naomi Byler, a member of Bridge of Life, one of the Healthfest sponsors.
