Snooki is, once again, slamming those who are critical of her 50-pound weight loss following the birth of son Lorenzo.

"People are jerks," the 25-year-old mom tells InTouch. "I don't look emaciated—I look healthy!"

She adds, "My arms still jiggle when I wave! I'm 4-foot-9, which is the size of a third-grader, so weighing 96 pounds is normal for me."

Snooki, who admitted she was at her heaviest weight of 146 pounds during her Jersey Shore days, credits her slimmed-down figure to intense workouts at the gym with a trainer.

A few months back, Snooki proudly posted a photo to Instagram in which she flexed her growing bicep muscles after some folks claimed she was becoming "too skinny."

"'Too skinny' my ass. #FIT," she wrote.

Of course, Snooki will soon find herself in even better shape.

After all, it was just announced she'll be hoofing it up on the upcoming 17th season of Dancing With Stars.

Now that's a workout!
