How to Calculate Serving Size?

You will need a kitchen scale to calculate the serving size accurately. And that’s because it essentially weighs the ingredients you need to prepare a meal. A kitchen scale also allows you to track the number of calories and macronutrients in your prepared meal. 

Whether you’re looking to bulk up meal size or you want to prepare a meal size to help you lose weight, a kitchen scale will be a valuable kitchen appliance. You will appreciate the precision of measurements by a kitchen scale. And this will result in the right amount of meal size that helps achieve your nutritional goal.

You can calculate the serving size by dividing the entire weight of the finished dish by the number of servings. Your recipe will show the number of servings most of the time. For example, you could prepare Green Chile Enchiladas for 6. In this case, you will divide the entire weight of the dish by 6 to get the serving size.
