Planning is very important, since in this way you will learn to organize yourself with your meals and you will end up creating a very good habit.
You can organize your weekly menus, so you will know what to buy and what you will eat that day.
If you have your diet planned, it is unlikely that you will skip any meal time, in this way it is possible to avoid consuming an excess of food or anything that you find within your reach, for having spent many hours without eating.
You save money, since by planning your diet you do not buy food that you do not need since you know that you are going to use it during the week.
You prevent food from being lost.
