Oh this is scary when I went to take a shower I noticed that I was skinny... and really skinny and it's not even funny I'M NOT JOKING!!! I measured me all around and the circumfrence of my waist is only 22 inches WTH??? I need some more body muscle. What can I do???

This is what I'm planning to eat for breakfast in the morning:
-1 donut
-2 pop tarts (chocolate fudge)
-1 bagel
-1 slice of toast

-And a bowl of cereal

Should I eat that?
