1. She Doesn’t Detox

McPhee said to Hello! Magazine that she doesn’t believe in extreme dieting, specifically detoxes. "I can't do that, it's too restricting for me," she said. "Personally, juicing is not interesting enough for me; I like to, like, eat my food. I love salads, I love clean food; it makes me feel good. But the idea that you can never eat a burger and French fries (without gaining) weight five days later? I just don't believe that's true.”

2. She Works Out Her Abs

McPhee is known for her flat stomach, so naturally, this means she does a lot of ab workouts. McPhee described some of her favorite ab exercises to Hello! Magazine. "I like a move on the bench where you bend. And the scissors are, like, crazy. It's the knees coming in and then out that works a different part of your lower abs. But it's really the number of reps that you're doing.”

3. She Loves Going To Classes At The Gym

While it can be difficult for some people to limit carbs in their diet, McPhee tells StyleCaster.com that she does this when she wants to lose weight. “If I really need to get serious and slim down, I won’t eat bread. That’s it. I’m not really a dieter.”

McPhee says to Health that she doesn’t skip leg day, and that her favorite workout is squats. “The jump squats into the bounce. For a solid minute, when you’re jump squatting on a bench, it’s a burn, and then after that, you stay in the position, in the squat, and he’s like, ‘Bounce. And bounce. And bounce.’ And it’s horrible. And then you go and do it, like, three other times.”

1. She’s Confident

McPhee is open about her previous struggles with body image and an eating disorder. After having her son, she opened up about how she found confidence and acceptance with herself. "What I didn't expect was to have the baby and then be so at peace with my body," she said to E! Online. "I had this, wow, like this huge appreciation of what my body had just done and given me that I wish that I'd given myself a little bit more of that grace through the pregnancy."

2. She Practices Yoga

McPhee shared some of her wellness secrets with Harper’s Bazaar. She says that one thing she does to stay fit is yoga. “I get a great workout from yoga, and I love the added benefit of being able to focus on breathing, quieting my mind, and meditating.” Better Health reports that yoga has a lot of benefits. “Researchers have discovered that the regular practice of yoga may produce many health benefits, including increased cardiovascular fitness, improved muscular strength and normalisation of blood pressure. Yoga is a renowned antidote to stress and promotes improved sleeping patterns. Over time, those who practice yoga report lower levels of stress, and increased feelings of happiness and wellbeing. This is because concentrating on the postures and the breath acts as a form of meditation.”

3. She Loves Smoothies

McPhee makes sure to eat a healthy diet. She tells Harper’s Bazaar that she loves to drink smoothies. “Most days I make a delicious flaxseed smoothie with almond butter, collagen powder, chia seeds, bananas, and berries.” Families Together Of Orange County reports that smoothies are a great beverage. “Because they’re packed with essential nutrients and healthy ingredients, smoothies can function as a natural energy booster, with fruits like bananas, green veggies, and fruit berries providing a powerful combination of vitamins, minerals and carbs that can fuel your body and keep you energized, all day long!”

4. She Uses Oils

McPhee has amazing skin, and she makes sure to take care of it. She shared some of her secrets in her Harper’s Bazaar interview. McPhee says that she likes to use oils. “I love massaging oils into my skin. The massage stimulates collagen and blood flow, and the oil feels and smells amazing on my skin.”

5. She Removes Her Makeup

McPhee shared some of her skincare tips and favorite products with Glamour. She says that she always uses makeup wipes to take her makeup off. “My morning and night skin care routines tend to be the same. At night, I am a big fan of Neutrogena wipes. I always have been. I also love the MAC wipes. I think they were the first to come out with those makeup remover wipes, and I've never had problems with breaking out with them. And there's just enough of a floral scent that it's pleasant.”

1. Acting Dreams

Booth knew she wanted to act from an early age. “I always sort of loved performing for my family when I was really little,” she says. “When I was twelve, I auditioned for Huron Country Playhouse, which is a summer stock theater in Grand Bend, Ontario, and I was cast as an orphan in the musical Annie. It was that summer when I was walking into the first rehearsal and saw the adults there, and I don’t know why I’d never put two and two together before while watching TV, but it was like a light bulb went off for me, and I was like, 'Wait a second. You can actually do this for a living?' And that was it. And I was like, 'That’s what I wanna do.'”

2. Her Perfect Saturday

Booth loves to just relax on the weekends. “My perfect Saturday would mean slightly sleeping in—to like, 10 a.m. I’d get up and have an almond milk latte that I make here with my little Nespresso machine that I love,” she says. “Then my husband and I would get the dogs all leashed up and go for a walk. We’d come back and probably go out for brunch to Bonjour Brioche—it’s on Queen Street East. My husband and I both love pancakes so we’d probably end up having them with fresh squeezed orange juice or something like that. Maybe a side of bacon, too—gotta have some protein!”

3. Horror Movie Fan

Booth is a big movie buff, enjoying both rom coms and scary flicks. “I have my favorites that I watch: The Princess Bride and Bridget Jones’s Diary,” she says. “Those are two of my go to feel-good movies. My best friend and I have a bit of a weird obsession with horror films, so generally when I’m at home she’ll come over and all three of us will sit around and watch really bad horror movies, like the remake of Nightmare on Elm Street. It’s so bad. It’s awful. But then there are some really great ones. We just watched the original—I think it’s Swedish—of Let the Right One In. I like to be scared—to sit for two or three hours on the sofa with my stomach in knots.”

4. Playing Ethel Kennedy

Booth once played Ethel Kennedy on The Kennedys and took it seriously. “Well, you know, the first time around, it kind of haunted me a little bit–I’m not gonna lie,” she says. “And even almost more so the second time. You’re portraying someone who lived this life, who is a part of history, who is still alive, and you obviously want to do them justice and portray them as close to who they are or who they were at that time as possible. I pored over biographies and books about the Kennedys, videos and all sorts of research material in order to create this character who then became Ethel Kennedy.”

5. Bubble Baths

Booth sometimes enjoys a bath as part of a relaxing Saturday. “Sometimes I’ll take a bath before bed—I do enjoy a good bubble bath,” she says. “I like lavender essential oil in it to help me sleep. But usually it’s just us crawling into bed and passing out. I’m sort of religious about washing my face before I go to sleep. But I will admit that on more than one occasion on a Saturday, I will skip that. That’s why I have towelettes on my nightstand!”

Kate Chastain is showing off her pregnancy body in a swimsuit. The former Below Deck star is enjoying her first pregnancy by making a splash on social media. “This was at 11 weeks pregnant (right before BravoCon!) before anyone knew but my boobs were amazing so im posting now,” she captioned the Instagram photo. How does she stay so fit? Read on to see 5 ways Kate Chastain stays in shape and the photos that prove they work—and to get beach-ready yourself, don't miss these essential 30 Best-Ever Celebrity Bathing Suit Photos!

1. She Listens to Music When She Exercises

Kate doesn’t workout regularly, but when she does, she stays pumped with tunes. “Um, what is this strange word ‘workout’ you speak of? I don’t really exercise that often (okay: more like never) but I am obsessed with music. I usually listen to a mix of hip hop and deep house mostly. Drake, Disclosure, Flume….I like to keep it pretty mellow,” she told Bravo.

2. She Is a Foodie

Kate loves herself some gourmet food. “I was lucky enough to go to Per Se a few months ago and that was unbelievable; refined defined. Thomas Keller is a genius. On an every day basis though, my first choice will always be sushi,” she told Bravo about her dream meal. When she was in Thailand she also indulged in the food. “I got Pad Thai yesterday and I think it was the first time since Thailand,” she told Decider, revealing that she ate a ton of it while there. “I think I’ll still wait another six months [to have it again].” She added: “I usually get chicken because I’m too lazy to go dog food shopping so I give some of the chicken to my dog.”

3. She Gets Deep Tissue Massages

Kate is all about a “good, deep tissue massage, although I don’t see it as that much of a splurge,” she told Bravo. “It’s more a medical necessity than a luxury. I carry all of my stress in my shoulders and if I don’t have it corrected after a while, even just sleeping can be a real pain in the neck. (awful pun, I know….couldn’t help myself).”

4. She Takes Me Time

When Kate needs a break she takes a break. “I felt the same way I do every season, like, what just happened, thank god it’s over, get me to a hotel. I stayed in Thailand for about a week and just chilled out. I know it was an expensive hotel, I had a private pool, I just needed seven days before I went back to the real world to decompress,” she told Decider.

5. She Drinks Espresso Spiked Martinis

Kate stays energized by adding a jolt to her alcoholic beverages. "Espresso martini in every country I visit," she wrote in an Instagram Story. "While past studies hinted that coffee might have a dark side, newer research suggests that it may actually have health benefits," says the Mayo Clinic. "Why the reversal? It's hard to look at just one aspect of diet and connect it to a health condition because so many other factors that could play a role. For example, early research on coffee didn't always take into account that heavy coffee drinkers also tended to use tobacco and be sedentary. When newer studies adjusted for such factors, they found a possible association between coffee and decreased mortality. Coffee may offer some protection against:

• Parkinson's disease
• Type 2 diabetes
• Liver disease, including liver cancer
• Heart attack and stroke."
