If you are having trouble making your diet healthier, start by eating anything you eat slower. A lot of people out there are fast eaters so they shove down plate after plate of fatty foods, tending to overeat before they even realize they are full. This habit leads to more calorie consumption which is a large cause of weight gain.
Before you eat all of your meals you should drink a glass or two of water. This will help you to meet your daily requirement of eight glasses of water per day, and it will also make you feel fuller so you will eat a much smaller food portion.
