Megan Fox
"Let me tell you: the first time [I had to lose post-pregnancy weight ]I didn't do anything. I was just lucky and I was younger. The second time it wasn't coming off the same way. I've had to eliminate bread from my diet. So I'm on that high protein very low carbohydrate, very low sugar diet." –Megan Fox to E! News

Doutzen Kroes
"When I am with my mum I am happiest and healthiest. She always taught me how to eat healthily. She always cooked from the garden and it was always organic. Growing up in the north of Holland, I had a healthy and balanced diet. When I travel, I don't really have the opportunity to eat healthily, so I try to go home for a week and a half every once in a while. It does me so much good to be in one time zone, rest every night and be outside." –Doutzen Kroes to Vogue
Erin Heatherton
"Starting the day of with a little bit of coconut oil helps digestion and is great for energy. I focus on the healthy foods I like - I love watermelon in the summer. I make sure I'm getting enough sleep, drinking lots of water and staying away from sodas and sugary drinks. I like to focus on eating healthy and feeling healthy." –Erin Heatherton to Vogue
Miranda Kerr
"I try to stick to an organic diet and stay hydrated with a lot of alkaline water." –Miranda Kerr to Vogue
Scarlett Johansson
"I exercise and eat well. I do it so I can indulge every now and then. I can have half a bottle of wine and not sit around thinking, oh my God, all those calories! However, when you're working and getting up at 4am to train for three hours every day, drinking isn't what you necessarily want to do. The discipline it takes to keep to that schedule sucks." –Scarlett Johansson
Miranda Lambert
"I didn't give up really a lot really. Just Cheetos mostly!" –Miranda Lambert to People

Salma Hayek
"I've been doing juice cleanses for 15 years... If I've been indulging in rich foods, a cleanse is a wonderful way to hit the reset button... My skin glows when I finish day three. And it inspires me to think about what I put in my body." –Salma Hayek to Marie Claire U.K.

Britney Spears
"I'm really into raw food — sushi, basically." –Britney Spears to Women's Health magazine
Lindsey Vonn
"It was hard to go to the Met ball [last May], with people who eat lettuce and a Diet Coke for dinner. It's difficult to be at events with a room full of women who weigh half as much as you do. That's always tough. I don't envy them, though, because so many of them are skinny-fat. They have more cellulite than most people."–Lindsey Vonn to Self
Emma Roberts
"As far as healthy food, I always am chugging coconut water I feel like it's so hydrating and it's not as boring as water." –Emma Roberts to E! News
Jennifer Garner
"There's something about it… whenever one of us [my husband Ben Affleck or I] has to be really good, the other one pudges up. I don't know why it is, but I blame my pudginess on his strict and disciplined place in life. There's something about it that just makes me like, 'Well, I'm gonna have a bonbon. I'm gonna have some ice cream.'"–Jennifer Garner to Ryan Seacrest
Laura Prepon
"I've always done crazy crash diets. I've ruined my metabolism that way. I did the hCG diet—[you're injected with] a hormone that's extracted from the urine of pregnant women!"–Laura Prepon on Health,com
