Much easier said than done. When it comes to truly understanding food and nutrition one of the toughest things to manage (at first) is your portion control. Being in America where most entrees are super sized it can be difficult to re-wire your brain. I am guilty of it often like when I go out to dinner. Have you ever been to a restaurant and you order a pasta dish and when you are served it looks like your entree could be for a family of four? Yet you gobble down the whole delicious carbs. I can name countless times I've done this too! You are not alone!
One really great way to start monitoring more of what you eat is understanding what actual sizes of foods you're consuming. For example, when you are cooking a new recipe you would follow the instructions on how many tablespoons or cups goes into what you're cooking. Similar concept for when you are eating. If you are at a family party with buffet styled food you have options of how much you want of each item. Instead of depriving yourself of all the "bad" carbohydrates or completely excusing any fats, wouldn't just be easier to know how much of each you could have? Without going completely off your weight loss plan!
