Drink Enough Water
Ilana said, "Rather than food right away, I recommend that each meal start with drinking water first." Aim to drink 16 ounces of water before reaching for your first bite of food. To help you remember, when you sit down to eat, make sure you have a big water bottle or two eight-ounce glasses. Ilana said you may find yourself feeling fuller, so you eat less.
Drinking tons of water throughout the day is also important not only to fill you up, but also because staying hydrated can give you energy so you're less tempted to reach for sugary pick-me-ups. No need to chug down a gallon of water a day, but aim for at least 60 to 80 ounces a day. If plain water bores you, add lemon or grapefruit slices.
