In Weight Watching Tips Used By Fit Moms Another good tip: Write down what you eat. You don't have to keep a food journal or write things from now on, but by writing down what you eat ( that means those two fries you ate from the kids happy meal, or that last bite of cookie they left at snack time ) and what time you ate the item, you can get a better idea of when and where you are doing most of your grazing ( one bite of this another of that). When you know your weakness you can change the habit.
