It’s already January 1 and already a new year has begun! While many of us are making resolutions to lose weight, spend more time with our loved ones, and become more productive, celebrity couple Kristen Stewart and Robert Pattinson have already resolved to become healthier.

The 24-year-old actress and the 27-year-old movie star have both put their health first this year, and have swapped cocktails for kale and quinoa. In fact, they’ve even swapped their regular hairstyle for a healthier alternative. We’ve collected some of the most interesting facts and figures about Kristen Stewart and Robert Pattinson’s health journey—and what they might resolve to do in the future.

Their Current Health Phase

Kristen Stewart & Robert Pattinson began 2018 healthy and fit. The couple began the year participating in a vegan experiment that featured them avoiding animal products and foods with gluten in them. They also avoided sugar, refined flour, and alcohol for a month. Later in the year, they followed up their vegan experiment with an even more stringent diet, consisting of only raw organic foods. They eliminated all caffeine and sugar from their diet, and began exercising regularly, running and working out with Robb Stark, their on-set bodyguard.

For three months, Stewart and Pattinson tried a no caffeine or sugar regime. They were very strict about meeting their daily requirements of fruits and vegetables. It was a healthy and fit phase for the couple, who began tracking their food intake and exercise regime closely. The stars were incredibly dedicated to this experiment, which undoubtedly required a lot of research and preparation.

What Is Their New Year’s Resolution?

The experiment didn’t last for long. In late September, Stewart and Pattinson gave up their raw food diet and returned to their usual eating habits. However, they remained committed to a healthier lifestyle, and began tracking their food intake and exercise more closely. These days, Stewart tracks the food she consumes and keeps a food diary, while Pattinson tracks his daily workouts and maintains a vegan blog. The two also continue to participate in vegan experiments, such as the one that saw them give up animal products and gluten in January.

For their part, Stewart and Pattinson have resolved to remain health-conscious and continue to promote a healthier lifestyle. The couple have also vowed to remain committed to their vegan experiment until they’ve mastered it. The next step could involve trying a gluten-free or vegan diet, or possibly eliminating one or more of the foods they eat. Whatever the case, they’re both determined to find the right nutrition plan and sticking with it. In the meantime, you can follow their progress on social media.

What Is Their Health Journey Like?

Since the outset of this year, we’ve seen a significant shift in Stewart’s and Pattinson’s health. A few weeks into 2018, we saw them hit the gym and shed off some pounds. Since then, they’ve continued to work out and monitor their food intake, maintaining a healthy weight for both of them. In fact, Stewart credits her weight loss to having found the right nutrition plan and the benefits of working out regularly.

Working out and eating healthily doesn’t come easily to Stewart. The actress has suffered from anorexia and bulimia throughout her life. During an interview with Elle UK in September, Stewart said, “I’ve always had a bit of a problem with my eating, I’ve always been very insecure about my weight. I feel like a freak at times because I can’t control my eating. And I know that’s not helpful, to feel bad about your body. I can control my body now, I can exercise and I can watch what I eat. Which is all very new to me.”

For her part, Pattinson has tried to manage his weight throughout his adult life. The movie star weighed over 300 pounds as a teenager and was put on a strict diet by his nutritionist. He then began working out and eating healthier, which ultimately led to him becoming more confident in himself and his appearance. It’s no secret that Stewart and Pattinson were raised in a household where both parents were advocates of self-love. These days, the couple are keen to share their journey with others, using their fame and social media platforms to help people understand what it means to eat healthily and how to maintain a healthy lifestyle.

The two continue to work out and watch their food intake closely. In fact, they’ve implemented many of these health changes into their daily schedules, which involve very little in the way of indulgence. They exercise regularly and try to maintain a healthy weight, consuming organic food and avoiding food products with added sugar. However, they also enjoy a drink now and then, which they say they won’t give up entirely just yet. We’ll see what 2018 brings for Stewart and Pattinson as they continue to work hard to shed off the pounds and keep up with their new nutrition and fitness plans. We’re sure it’ll be an interesting journey, and we’re eager to follow their progress.
