Consuming too much in one sitting

On this last day of the month, I hope to really preplan my meals and snacks effectively.  In fact, I would like to know about that since I am watching videos.  For someone such as myself who is trying to lose weight, I find that planning out meals in advance is essential to not overeating.  Today, I have consumed more fruits and vegetables than I usually would consume.  However, I realize that I do consume too much food in one sitting.  Instead of two drumsticks, I should have consumed just one drumstick with brown rice and maybe a vegetable.  That is just an example.  I do consume too much in one sitting.  That is the lesson that I have learned for today.
