Daily Calorie Intake

This app can be used to estimate the number of calories a person needs to consume each day. This Daily Calorie Intake app is based on several equations, and the results of the app are based on an estimated average. The Harris-Benedict Equation was one of the earliest equations used to calculate basal metabolic rate (BMR), which is the amount of energy expended per day at rest.The value obtained from these equations is the estimated number of calories a person can consume in a day to maintain their body-weight.

The average woman needs to eat about 2,000 calories per day to maintain her weight, and 1,500 calories per day to lose one pound of weight per week. Meanwhile, the average man needs 2,500 calories to maintain, and 2,000 to lose one pound of weight per week.


Daily Calories Intake is determined based on the Basal Metabolic Rate (BMR) calculation.
The BMR calculation using Formula:
Woman: dci = 655 + 4.35 × w + 4.7 × h - 4.7 × age
Man: dci = 66 + 6.23 × w + 12.7 × h - 6.8 × age
Where:
h: Body height, in inches
w: Body weight, in pounds (lbs)
age: in years
dci: Basal Metabolic Rate, in calories

Harris Benedict Formula is then used for Daily Calories Intake calculation:

sedentary, desk job: Calories = BMR x 1.2
light exercise/sports 1-3 days/week: Calories = BMR x 1.375
moderate exercise/sports 3-5 days/week: Caloriees = BMR x 1.55
hard exercise/sports 6-7 days a week: Caloriees = BMR x 1.725
very hard exercise/sports plus physical job: Calories = BMR x 1.9
