These could also work for the last straw wake up calls as well...

Not being able to wear sleeveless shirts

Seeing the horrified look on DH's face when I managed to squeeze myself into a cheap Walmart bathing suit during our summer vacation last June

The realization I weighed more than most of the baseball players on our local team

Being the fattest person in my work department

Weighing almost double what my 20 yr old DDs weigh

Sweating like a pig in the summer, spring, fall and winter

Living to eat versus eating right to live
