Well these pics might make you second guess that second helping of mashed potatoes.
"The Hunger Games" star Jennifer Lawrence hit the beach in Hawaii yesterday in a skimpy two-piece bikini -- looking great as she went to surf while on vacation with her family.
Lawrence is in killer shape, but weight isn't something she says she obsesses over.
In a recent interview with Elle magazine, Jennifer says she's "obese" by Hollywood standards and talked about the pressures of being in the biz.
"I've never really dieted or wanted to diet, or anything, and I just feel like, it's something that really overwhelms our industry in an unfortunate way," Lawrence says. "It just kind of becomes this distracting dark cloud."
Whatever she's doing (or not doing!), it's working for her.
