Weigh everything after cooking except the dry cereal in the morning. (For example, weigh your oatmeal dry and then cook up with water.) Veggies, protein, other kinds of grains like rice or potatoes, and everything else should be weighed after cooking. This is important. For example, if you weigh out a 4 oz. hamburger patty before you cook it, after it comes off the stove it will weigh about 2.7 oz. What this means, though, is that you won’t be able to cook single servings of food unless you overshoot the mark and cook up what will definitely be enough. Therefore, we always recommend cooking several servings of food at a time, and then having leftovers for the next day’s lunch, etc.
