Can I pay weight loss expenses with my HSA?

As part of my participation in the personal finance bloggers weight loss challenge I decided to investigate what weight loss expenses I could pay for with my Health Savings Account (HSA).

The short answer is no, you can't use your health savings account to cover the cost of getting in shape but there are a few exceptions.

After taking my most pressing question, "Is the fact that my doctor told me I should lose weight at my last appointment enough to make a weight loss class eligible to be paid by my health savings account?" to several experts I asked Fred Adams, "The HSA Expert", to give it to me straight.
