In an interview with Shape, Brinkley said, “For many, many, many years, I've always said go for as many colors as possible in a day.

For Brinkley, wellness is extremely important. She says that wellness is a lifestyle for her, and that she puts a lot of time and investment in it. Brinkley told The Cut, “For me, [wellness is] a lifestyle, it's a foundation for your future. Because your health is your greatest wealth. I really think that's something everybody needs to invest in."

3. She’s Vegetarian

Brinkley is open about enjoying a vegetarian diet. She says that she is an animal lover, and that this pushed her to cut out meat. Brinkley says that she’s also tried several other meat-free lifestyles over the years, but has stayed constant with her vegetarian diet. “Over the years I've been a vegan, I've been a macro-biotic, I've been a lacto-ovo,” she said to The Cut. “The one constant since the day I stopped eating meat was that I haven't eaten any red meat or fowl."

4. She Did Research, Before Changing Her Diet

Before Brinkley became a vegetarian, she had to do a lot of research. She knew that she’d be cutting out a major source of protein in her diet, and wanted to make sure she’d still be eating a balanced diet without meat. “When I became vegetarian I started reading books right away because I knew that I had to replace the protein and figure out what to do,” Brinkley told The Cut.

5. She Loves Oatmeal, Raw

Brinkley tells Shape that she eats pretty healthy each day. For breakfast, the model’s go-to is oatmeal, and she loves to put other healthy ingredients, like berries, in it. Brinkley also says that she enjoys it raw. "I rarely have time to cook it, so I just eat it raw. Then I'll pour some flaxseeds on top of that and maybe a little wheat germ, then I'll grab a couple of handfuls of blueberries, blackberries, raspberries and rinse them off and toss them in.”

Model Christie Brinkley is known for her beauty and her amazing body. Even at 67, Brinkley still looks the same as she did at her peak. She posted a photo on Instagram yesterday, clad in a swimsuit/bodysuit with a bottle of booze. “I’m bringing my award winning @bellissimaprosecco Bambinis to (Drum roll please) @qvc where we always offer you very special prices,” she said in the post. THIS THURSDAY in the 4:00 Hour.” Read on to see the five ways Christie Brinkley 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 Bikini Photos!

1. She’s A Vegetarian, But A Flexible Vegan

Brinkley is an animal rights activist, works with PETA, and is open about being a vegetarian. Brinkley told Harper’s Bazaar, "I haven't touched a piece of meat since I read a graphic description of Chicago's slaughterhouses when I was 12.” However, she told The Cut that she occasionally follows a vegan diet, with some conditions. She jokes, “I call myself a flexible vegan because, you know, Italy exists. Mozzarella and pasta exist. In France, I may have to have a piece of Camembert, you know. Un petit sandwich au fromage.”

2. She Starts Her Day With Lemon Water

Brinkley has a special drink that she likes to start her day with. She tells The Cut, “I start every day with warm water and lemons. It’s something I picked up on my Instagram.” Brinkley sometimes will add other things to her beverage. She says, “Some days I alter it, and I get fancy and I put a little bit of mānuka honey on the rim of the glass, turn it upside down, and dump it in red cayenne pepper. Then I put the lemon juice in and then the hot water. That’s when I have a little time. I figure that the pepper gets my system all revved up, and the lemon water gets everything flowing through.”

3. She Eats A Large Healthy Breakfast

Brinkley revealed her typical diet to Harper’s Bazaar, and her breakfasts are quite large, but are very healthy. “I have sheep's-milk yogurt from Old Chatham Sheepherding Company mixed with organic blackberries, blueberries, raspberries, papaya, chia seeds, raw oatmeal, and walnuts. If I want protein, I'll have an egg-white omelet with spinach and mushrooms.” Brinkley is also a coffee lover, and her Instagram followers are well aware of that. "Every morning I make myself a cappuccino with a drawing in the foam. I post them to Instagram with the hashtag #christiecappuccino.”

4. She Fits In Small Workouts Throughout Her Day

Brinkley told The Cut that she tries to do little physical activities each day, rather than doing one gym workout. "When I was doing Chicago, I noticed that the second you do any activity and you add your arms as though you're dancing, it revs you up. Whether it's walking down the beach and moving your arms like you're swimming, or picking up rocks and walking with them, you really start sweating and breathing heavily." Brinkley even squeezes smaller exercises when doing the smallest things. “While I'm brushing my teeth, I'm doing leg lifts. When I'm drying my hair, I do all kinds of squats.”

5. She Has Her Go-To Exercises

Brinkley does have some exercises that she likes to go to. Brinkley tells Harper’s Bazaar, "Everyone asks if I really use the Total Gym, and I do! It's perfect for stretching and lengthening my body. Last summer I got into SoulCycle, and in the winter I do yoga at Yoga Shanti. I enjoy bicycling, paddleboarding, surfing, skiing, and swimming too."
