Christie Brinkley, a renowned actress, entrepreneur, and model, recently appeared on "FOX & Friends" to discuss her latest memoir, "Uptown Girl." The book provides an intimate look at Brinkley's journey from her early life to her marriages and illustrious career in the spotlight. At 71, Brinkley still feels like the "Uptown Girl" she once was, and her memoir explores both her triumphs and the pitfalls she encountered along the way. During her appearance, Brinkley shared insights into how she has maintained her camera-ready appearance over the years. She emphasized the importance of her vegetarian lifestyle, a choice she made as a child and has since evolved into veganism over the past year. Brinkley encouraged viewers to consider adopting a vegetarian or vegan diet, highlighting the health benefits and positive impact on the planet. She is a proponent of the "rainbow diet," which involves consuming a variety of colorful foods rich in vitamins and minerals. For Brinkley, good nutrition is not about deprivation but about making informed choices that fortify the body. Brinkley stressed that her approach to eating is no longer about dieting. Instead, it's about understanding the effects of food, vitamins, minerals, and exercise on one's body chemistry. She recalled experiences from her early modeling career when she was put on restrictive diets to shed pounds quickly. Nowadays, she believes in moderation and refuses to deny herself the foods she loves, like a slice of birthday cake, as long as she balances it with mindful eating. Reflecting on her life, Brinkley shared a piece of advice she would give her younger self, quoting a line from her ex-husband Billy Joel's song "Vienna": "Slow down, you crazy child, you’re so ambitious for a juvenile." She emphasized the importance of savoring life and living in the moment. In 2021, Brinkley revealed that she doesn't use a scale to manage her weight. Instead, she relies on how her clothes fit to gauge her fitness level. She believes in smaller portions, more exercise, and focusing on gratitude to maintain a positive outlook. Brinkley has always been passionate about staying active. She enjoys a variety of sports and outdoor activities, including tennis, paddleboarding, skiing, kayaking, and cycling. For her, movement is essential, especially as she grows older. She advises against a sedentary lifestyle, recommending people seek physical therapy to address any aches and pains and to strengthen their muscles. In addition to her career and wellness insights, Brinkley is a proud mother of three and continues to inspire with her approach to life. Her memoir, "Uptown Girl," is now available, offering fans a deeper understanding of the woman behind the public persona.
