Kaley recently became less restrictive about her diet, which was a total game changer. "I'm much healthier now than I used to be. And I feel better than I ever have, but I also probably eat more than I ever have, which is interesting," she told Women’s Health. "I'm actually eating smaller meals and drinking more water and less alcohol." She added that it all boils down to knowledge. "I think I used to be afraid to eat, and now I just know the right things to eat. There's a huge difference."

2. Her Diet Is Clean and Fuels Her Body

Kaley starts the day with a piece of sourdough toast slathered in peanut butter. For lunch, she always has something with tuna. "I love tuna, [I] love it on a salad, love it in a wrap, love it in its own scoop, love it with chips. I'm like obsessed with tuna," she told WH. Dinner usually consists of protein, like grilled salmon with baked potato and veggies. "If I had to say what I eat most, it would be salmon," she said.

3. She Eats Every Two Hours

"I learned over the past few years that I have to eat every two hours," Kaley told WH. "I just do, and I'm not talking about giant meals, but I literally start to fall apart, especially when I'm shooting...there has to be at least a snack or something that I'm eating because I just lose energy so quickly."

4. She Drinks Smoothies

"I love a smoothie," Kaley told WH. "I think it's a great way to get a nice meal in there, and it's quite easy." Her "favorite fruit in the whole world"? Pears.

5. She Has an Eating Out Rule

Kaley has a go-to rule she learned from her nutritionist, who she has been working with since she was 15. "If I go to dinner, she immediately wants me to cut my plate in half," she told WH. After eating half she will "take a little break" and then keep eating if she is still hungry. However, "nine times out of 10," she realizes she is full. "Our eyes are definitely bigger than our stomach," she said.

6. She Has a Sweet Tooth

Kaley is "candy obsessed" but also loves salty snacks. "I love the act of [eating] popcorn and watching a movie," she told WH. However, she avoids sweets at night. "I just don't feel good after, and I don't feel good when I wake up."

7. She Doesn’t Watch TV While She Eats

"I no longer watch TV while I eat,” Kaley revealed to WH. “I think that's a big distraction 'cause you're not thinking about what's going on...so it's just being very mindful.”
