What to eat??
Getting rid of fat is a matter of, on average, burning more calories than you eat, which is called a caloric deficit. There are many ways to go about doing this. Basically though, it comes down to eating less and exercising more.
You might want to use the app 'myfitnesspal' which is a very useful app for setting your goals and counting calories. Some basic ideas : when cutting calories, you'll want to make the ones you do eat count. This means not eating empty calories like junk food, which will leave you hungry still needing nutrients.
Cut almost all added sugars. Cut most processed foods. Avoid liquid calories, stick with mostly water or unsweetened coffee or tea. (I'm not sure if your fruit infused water has calories but if not then ok)
Eat way more vegetables. They are extremely low in calories and high in nutrition. Fill a couple containers with chopped cucumber & carrots &/or whatever you like fresh. Sprinkle a little seasoned salt on if this helps. Eat those throughout the day as snacks or meals.
Small servings of nuts, plain yogurt with added blueberries (blueberries are a low sugar fruit & quite convenient to buy frozen), fish, canned tuna or salmon, cottage cheese, eggs, (a boiled egg is a good protein snack) chicken breast, salad with olive oil & a sprinkle of seasoned salt...
If you use myfitnesspal, you'll gain a deeper understanding of what you eat and what it offers your body. It takes a bit of getting used to, and some investment of time to dial things in.
Good luck. Don't get too discouraged if you can't do it all perfectly from the start. Just try to incorporate some better habits and keep coming back to them and adding more as you can. You're going to face setbacks, like anyone else. For me, I've found the trick isn't in never straying from the path, the real trick is always returning to the path after I stray.
