1) Definitely, definitely commit to drink a sufficient amount of water every single day, whether it's coming from regular water, sparkling water, or tea. The amount is going to differ for different people. That means at least a liter of water a day up to three liters, depending on activity level and what your body requires. If you're drinking other things, you're either going to be dehydrated, which impacts digestion and energy, or you may be taking in excess calories from beverages that we just don't really need. 2) Use fresh fruits and vegetables whenever possible. Specifically, I encourage my clients to try to have a fruit and/or vegetable at almost every meal if they can. That could be a banana in your cereal in the morning. It could be a vegetable soup at lunch or a salad at lunch. It could be some sautéed broccoli, roasted root vegetables or grilled asparagus at dinner. Allow fruits and vegetables to fill you up with fewer calories. They should be the majority of food on any given plate.
