WTF

This is not an angry post, just a very confused post.

So, after all that I ate this weekend...

-Avocado bacon cheeseburger + fries + soda.
-Carne asada fries + part of a carne asada burrito.
-At least 2 cans of Pepsi.
-2 double chocolate cookies.
-$2.50 worth of Yogurtland.
-Chipotle burrito bowl.
-Carne asada burrito + chicken burrito.
-Filet mignon, twice-baked potatoes, creamed spinach, bread pudding.
-Pizza rolls.
-Fried rice.
-Cheeseburger.

....I managed to lose 3 lbs. from Friday to today (and I haven't weighed 128 since middle school.) This was without exercise, and consisted of me sitting on my ass (I watched 3 movies) for at least 75% of the weekend. I did walk around in heels every day, so that might have caused me to work my muscles out, but still, do I have a parasite or something??
