Diet may seem like a secondary issue for many of us, but for athletes, it plays a very important role. The food they eat today could change the course of their game the next day. Athletes like tennis superstar Novak Djokovic have special diets that help them perform their best. Sharing the juices he drinks every morning in an interview; we get a glimpse of what goes into being a professional player. Why Does A Diet Play An Important Role Different sports require different types of diet, for example John Hopkins Medicine explains that a runner athlete must go for a carbohydrate rich diet as they must expend a lot of energy in an extended period of time, meaning they must sustain a uniform strain of energy to make sure they complete their run. On the other hand, judo or wrestler athletes must focus on a protein-based diet that will help them build muscles and strength. For elite athletes, every little detail matters – from what they eat to how they train and recover. It can all make the difference between winning and losing. When it comes to fueling the body for success, Novak Djokovic stands out. With an astonishing 24 Grand Slam titles, he's the most successful male player in history, surpassing even legends like Rafael Nadal and Roger Federer, and he's still competing at the highest level. What Does Novak Djokovic Eat? Recently, in a TikTok clip with sports journalist Graham Bensinger, Djokovic revealed a surprising part of his daily morning routine. When asked about a typical day, he shared: "When I rise from bed, I start with warm water and lemon so I can help my body to detoxify and then I would have celery juice on an empty stomach." While this might sound a bit unusual to most people, Djokovic's drink choices are actually supported by some interesting science. Science Behind the Sips Warm lemon water is a fantastic natural source of Vitamin C. This vitamin is crucial for many bodily functions and significantly boosts your immune system. It's also a powerful antioxidant, helping to fight off harmful molecules called free radicals and keeping your cells healthy. Drinking this first thing in the morning, as Djokovic does, can also be great for your digestive system. The Cleveland Clinic explains that it also helps us stay hydrated and is a great remedy for kidney stones, weight loss friendly, as well as filled with antioxidants like vitamin C, protecting your body from diseases. Adding celery juice to the mix offers similar benefits. It's also rich in Vitamin C, along with Vitamins A and K, and essential nutrients like potassium, folate, and magnesium. For a tennis player like Djokovic, Vitamin K is especially important for strong bones, while the other nutrients help with muscle recovery and healthy blood flow. Beyond the scientific benefits, Djokovic himself says these drinks give him mental clarity and a general feeling of energy, setting him up for a positive start to his day. Even if you're not planning to follow the exact routine of a world-class athlete, staying hydrated is always a good idea. The NHS recommends drinking six to eight cups or glasses of fluid throughout the day. Do We Need Detoxifying Juices?As an addition to your diet, these can be helpful, however many people go on juice cleanses, relying solely on the juice for sustenance, which is not healthy for your body. A big selling point for juice cleansers is their supposed ability to "detoxify" your system. It's true that drinking more fluids can help your kidneys work better, and some nutrients can assist your body in getting rid of waste. However, there isn't enough scientific evidence to show that juice cleanses or other "detox" diets actually improve your body's natural ability to remove toxins. Your liver and kidneys are incredibly efficient at detoxifying your body on their own, without the need for special juice regimens.
