has pulled a Jonah Hill ... the comedian dropped more than a hundred pounds in the last year and now she's showing off her new bod.

Lisa posted the photo on Instagram today, more than a year after undergoing a sleeve gastrectomy -- a type of gastric bypass surgery. The progress is really impressive, but Lisa has insisted it's not a permanent fix. She still has to alter her eating habits to keep the weight off.
