Louise follows a vegan diet, and frequently posts photos of her vegan meals on social media. "Plants give your body what it needs to help fight off infection," says Andrea Murray, MD Anderson health education specialist. "A plant-based diet strengthens your immune system to protect you against germs and microorganisms… Antioxidants in plants grab all these so-called free radicals that can throw your body off balance. To reduce inflammation, it's important to eat plant-based and to listen to your body's signals for how foods work for you."

Louise loves getting outside to exercise in the fresh air and sunshine. "Hiking is my favorite form of exercise," she says. "Not only does hiking keep you healthy and raise your level of cardiovascular endurance, here are 4 other benefits on why hiking is good for your health: 1. Builds Bone Density 💪🏼 2. Improves Sleep Quality 💤 3. Boost Happiness 😁 4. Combat Depression 😞🙅🏼‍♀️ So what are you waiting for get outside and start walking!!"

Louise enjoys fresh watermelon, especially in drinks. "Did you know watermelon has more lycopene than any other fresh fruit or vegetable?" says Kristi Wempen, RDN. "Lycopene is an antioxidant linked to decreased risk of cancer, heart disease and age-related eye disorders."

Louise loves to do mountain climbers as a warm up. "Quick workout before I start my day -one of my fav go to exercises is mountain climbers, working several joints and muscles at the same time -in particular, it targets your triceps, deltoids, abs, back, hip flexors, quads, hamstrings and butt!! 👀🍑 Done explosively, mountain climbers will shoot your heart rate up in a matter of seconds," she says.

Louise loves to make her own freshly squeezed lemon juice. "Some evidence has linked vitamin C (or ascorbic acid) and flavonoids, which are protective compounds found in citrus fruit, to improvements in skin condition," says registered nutritionist Jo Lewin. "Vitamin C is known to help the body produce collagen, which contributes to the integrity of the skin. Interestingly, a study in 2016 indicated that a citrus based juice drink may help prevent the damaging effects that lead to premature skin-aging in mice."
