Even after you lose weight, it’s a good idea to keep a food journal. Why? Because it prevents you from slipping back into your old habits–the ones that caused you to gain all that weight you worked so hard to take off!
You don’t have to keep a journal every day or every week but it’s a good idea to write down what you eat for a few days each month. Keep a reminder on your calendar. Or, if you’re sitting waiting somewhere, take out a piece of paper or your smart phone and just jot down what you had to eat that day or the previous day.
Writing down what you eat has several benefits. One, you see patterns starting to form. Are you starting to eat more fried foods? Drinking more high calorie beverages? Two, you have to think about portion sizes. Did you have one cup of cereal at breakfast or did you just fill the bowl and not think about it? And three, it makes you count those little bites that you would rather not think about, like that chicken nugget you stole from your son’s plate or those fries your daughter didn’t finish.
