Meal prepping require some mathematical planning to ensure that the amount of food that you cook is the same as the amount of food that you plan to eating. Many people attempt to meal prep but usually end up with a shortage of the food they need before the week is over because of the difficulty of estimating portion of food. You must account for the number of meals that you will eat during the week, your appetite, and the shrinkage of food during the cooking process.
When you cook food, it often loses some of its water during the cooking process, and food can also be lost to sticking to the pans in which it are cooked. To account for this, you should make an allowance for food waste when meal prepping. This waste buffer will ensure that if you plan on having five meal during the week, you will have five full meal and not four and a half meals that are lost during the cooking process.
How to Plan Meal Portions and Store Food
You must take into account your appetite when meal prepping. The appetite that you plan for should be one that reflects your hunger levels during the week. Many people plan for there appetite on the day that they meal prep.
However, their appetite may be higher during the days that they are more physical active during the week. If you use an inappropriate portion size for your appetite, you could end up feeling hungry throughout the week that will lead to eat extra snacks. This can defeat the purpose of meal prepping.
It is better to prepare extra food than to find themself short of food during the week. The size of the container in which the food will be stored should also be account for in the meal prep process. The volume of the food and the volume of the container should be equal.
You can use the reference tables to ensure that the container that you use has the appropriate size for the types of food that you are preparing. For example, one cup of rice will take up less space in a container than one cup of broccoli. If the container of food is too small for the portion of food that will be placed in it, the food could be compressed within the container to account for the space, which could ruin the texture of the food.
If the container is too large for the food, the food could move within the container, which could cause the food to dry out in a refrigerator. Another factor to consider is the method of storage. Food stored in a family tray will not have the same calculations as food stored in individual lunch box.
The family tray will have more surface area in which the food can lose moisture. You should round the total amount of food that you will prepare when meal prepping to make shopping for the food easier. It is difficult to find items in stores that weigh exactly the amount that you calculated when meal prepping.
You should round the measurement to the nearest half pound or cup of food for ease of shopping for the meal. Another factor to consider when meal prepping is the placement of the prepared meals in the refrigerator. You should place the oldest meals at the front of the refrigerator.
This will ensure that the food is consume in the order in which it is prepared. The containers of food should also be labeled with the day or the date that the food is prepared. Labeling the containers will remove the guesswork of when certain meals were prepared.
This will ensure that you do not consume spoiled food. By labelling the containers with the dates of preparation, and placing the oldest meals at the front of the refrigerator, you have ensured that every meal is accounted for from the beginning of the week to the end of the week. Another thing to consider when meal prepping is the type of containers in which the sauces will be stored.
It is best to place sauces in separate containers from the food that they will be poured over. If you mix the sauce into the food when meal prepping, the food will absorb the liquid from the sauce. This will make the texture of the food soft and mushy.
By placing the sauce in separate containers, you can keep the texture of the food that you prepare intactly.
