I fill in what I've eaten on my nutrition planner right after I eat lunch. I've found that this way, I can keep a close eye on the nutrition values and plan accordingly for my evening meal.
Whether I've eaten more than normal for breakfast and lunch, or not eaten enough, I can work my evening meal plan around all those values, and adjust up or down whether it's carbs, fat or protein. I make adjustments to keep me within my calorie range and keep me satisfied with the foods I've chosen.
I've found that for me, this is a no fail method of tracking my food and keeping me in line with calorie intake, carbohydrates, fat and protein grams as outlined on my Nutrition Planner.
I never skip a meal and breakfast is my most important meal of the day.
