Snacking on the right things is one of the secrets to a great body and a healthy lifestyle and Hollywood's hottest stars know it. From Olivia Munn's favorite apples and peanut butter combo to Molly Sims' go-to Greek yogurt, check out what snacks are celebrity approved in the gallery below. 

The country songstress never leaves home without something to nibble on, like popcorn. "I always keep snacks in my purse when I'm out because I get brain fog when my blood sugar drops," Underwood, 38, confessed. "My mouth moves but my sentences don't make sense."

She enjoys her sister Haylie's black bean chocolate cake, but the 33-year-old Younger actress likes to keep everyday munchies on the lighter side. She's called watermelon chunks topped with tajin and lime "one of my fave snacks."

Sims conquered constant grazing by keeping Greek yogurt and bags of banana chips and dried mango slices at the ready. "The biggest pitfall I've had... is eating my kids' snacks," the model mom, 47, admitted. "I used to be a picker. Now, I'll literally prepackage my snacks. I try to plan things out more." So smart!

"I love to make healthier snacks," Mowry, 42, shared. Case in point: Her crunchy, spicy chickpeas, which she coats in spices, soy sauce, olive and sesame oils, and then bakes for an hour. "[They are] delicious."

"I like simple, whole foods," the 48-year-old Black-ish actress revealed. That applies to snacks too — one of her mainstays is avocado toast with lemon, crushed red pepper and salt on Udi's bread. "I eat in the same philosophy that I live with," she's said, "joyfully!" Hear, hear!

The ridiculously fit 52-year-old swaps out ice cream for a more nutrient-dense, but just as tasty sweet treat — frozen grapes. "I like the red ones — they're really easy and delicious," she noted. "They give you that frozen crunch."

The Newsroom alum, 40, sticks to apples with peanut butter but occasionally switches things up. "I'll go for almond butter if there are people around me that are super healthy," she shared, "because I hate the judge-y looks."
