Tommasi's favorite lunch is buffalo mozzarella and tomatoes. "Tomatoes are packed with vitamins and minerals that are essential for a healthy body," says Robert H. Shmerling, MD. "They are a great source of vitamin C, which is important for boosting the immune system and fighting off infections."

Tommasi enjoys fresh grilled fish with plenty of greens. "Fatty fish like salmon, sardines, and tuna are high in omega-3 fatty acids, which have been shown to reduce body fat," says Caroline Buckee, D.Phil. "In addition to aiding weight loss, fatty fish is also high in protein, which helps keep you feeling full for longer."

One of Tommasi's go-to snacks is a bowl full of olives, a staple of the Mediterranean diet. "Many studies continue to confirm the health benefits of the Mediterranean diet, which cuts the risk of heart disease and stroke," says Howard E. LeWine, MD. "The diet's nutritional benefits probably come from various sources, but the generous use of olive oil appears to be a key contributor." 

Even when she's traveling out of Italy, Tommasi can't resist a bowl of pasta, another staple of a traditional Mediterranean diet. "At its core, the Mediterranean diet is a plant-based diet that focuses on lean meats, like poultry and fish, fruits and vegetables, whole grains, nuts, legumes and heart-healthy fats, especially olive oil," says Jennifer Oikarinen, a registered dietitian with Banner Estrella Medical Center in Phoenix. "Although it puts limits on red meat, added sugar, refined carbs and other processed foods, what many people love about the Mediterranean diet is it emphasizes more what to eat, instead of everything you can't."

Tommasi's favorite way to explore a new city is on foot. "You may start out as an average walker, and then work your way up to walking faster and walking a mile in a shorter amount of time than an average walker, similar to power walkers," says the Mayo Clinic. "This can be a great way to get aerobic activity, improve your heart health and increase your endurance while burning calories."
