Bonus when picking up that's small enough for the plastic to fit around, just like picking up after a four-legged pet: turn the bag or other wrapping material inside-out, tie it up at the top, and you have a sealed trash bag that's "clean" on the outside!
And I lost a lot of weight as well and then realized I wasn’t getting enough carbs (I know, right?) to fuel my workouts and to keep me going through the day.
