You are not kidding about companies. The company I work for has gone to great lengths to focus on health and wellness issues. But every Friday the donuts/cakes/brownies, etc. roll in and it is the same overweight people that spend half the day by the food. We pay partial gym memberships, promote tests employees can take to reduce health risks and they are basically unused.
Occassional good stories though. Through the wellness testing an employee with diabetes and one with extremely high blood pressure were uncovered. They made lifestyle changes and are doing fine.
