How much food do you need a day?
How much food/energy do you need a day?
The minimum number of calories needed to sustain life varies greatly depending on several factors, including a person's age, gender, weight, height, and activity level. However, a general estimate of the minimum number of calories required to maintain basic bodily functions is around 1,200-1,500 calories per day.
It's important to note that consuming this minimum amount of calories would only sustain basic bodily functions and would not provide enough energy for physical activity, growth, or to support a healthy immune system.
As a general rule of thumb the average basal metabolic rate for a human is 22 kcal per day per KG of body weight, or 10 kcal per pound.
So, as an example, an individual who weighs 140 lb will require a minimum of 1,400 kcal per day, or someone who weighs 200 lb will require a minimum 2,000 kcal per day.
In addition to this calorific minimum value, additional physical work, activities and exercise will burn additional calories, resulting in a typical overall daily energy requirement as indicated below:
Daily Guidelines - typical energy intake
|15 to 19||3,100 kcal||2,500 kcal|
|19 to 25||3,000 kcal||2,400 kcal|
|25 to 51||2,900 kcal||2,300 kcal|
|51 to 65||2,500 kcal||2,000 kcal|
|over 65||2,300 kcal||1,800 kcal|
