More and more people save money and time by cooking several days' worth of meals to freeze for later consumption.
Lee Jae-hoo (33) started meal prepping a month ago. Lee and his wife each cook two or three different meals at the weekend and freeze them so they just warm them up during their busy working week.
"Both my wife and I work, so we often had food delivered, which made us fat and gave us digestive problems," Lee said. "But now, even if it takes four or five hours to prepare the meals, we can eat healthier and save money as well."
Singles and double-income couples often eat out or have their meals delivered, but now they are looking for healthier and cheaper alternatives.
Meal prepping also allows people to calculate how much protein, carbohydrates, fat and minerals they consume, while limiting their daily calorie intake to recommended levels of 2500 kcal for men and 2000 kcal for women.
Foods that go bad easily like eggs, fish and vegetables are better avoided or included in meals that will be consumed in a couple of days so that they do not need freezing.
Prepared meals should be stored in microwaveable and freezable containers and be allowed to cool sufficiently because the condensation that forms from hot food can spoil the food in the fridge.
