Is this an ongoing thing ? If so I suggest "May there be Abs" for May. Of course this horrible, But I'm not exactly creative.
I was actually thinking of something along the same lines, maybe "May the yokedness be with you".
I didn't weigh myself for about 10 days and when I weighed myself on Friday I was down to 212. Progress, huzzah!
Maybe being punched in the jaw really hard has weight-loss effects.
