Obese health and fitness director

I don’t feel like saying this to anyone here at work, so sorry people, but I need to dump on you. I work in a company with 2,500 employees. The company encourages healthy living, and is always having in house programs to lose weight. Not many people ever sign up for this. I believe the underlying issue is with our health and fitness director. In the six years I have worked here she has gone from overweight to obviously obese, and is commonly seen getting candy and chips from the vending machines. Why, oh why do they have someone like that telling us to be healthy? It makes no sense at all.
