This is so much bull!!! You can have diabetes and not be overweight (such as my mother), you can have high blood pressure for no other reason then that you are stressed or you inherited the tendancy!! So what if you have these problems and they are not obesity related? Do you still have to pay the $50.00 fee?

Four years ago, PepsiCo (PEP) began rolling out a wellness program that charges its employees $50 a month if they smoke or have obesity-related medical problems such as diabetes, hypertension, and high blood pressure. Workers can avoid the surcharge if they attend classes to learn how to break their nicotine addictions or lose weight.
