This author is not fond of counting calories. Though its interesting to stumble upon an article about the history of children’s school lunches. The caloric intake in the past were: 2400-2800 for gals. 3400-3800 for guys.
Nowadays, the guidelines are as follows:
kids ages 1 to 7 often require 34 to 41 calories per pound of body weight daily, children ages 7 to 12 need about 27 to 34 calories per pound and kids age 12 to 18 often require 13 to 27 calories for each pound of their body weight daily. Exceptions may occur in overweight and obese children.(1)
Kids in general do more than adults. Unfortunely, as they get to their teens, they become stationery. As a result, the caloric intake should be less. At the same time, we will need to take into the account of their development. The caloric intake should be customized rather than standardized.
According to UN, developing and undeveloped countries are not getting enough calories. Either way, obesty and malnutrition costs a great deal of health bucks. Prevention, education and tools are the key to deal with good eating habits.
