The Harris-Benedict equation for BMR:
◦ English BMR Formula For Women: BMR = 655 + (4.35 x w) + (4.7 x h) - (4.7 x a) For Men: BMR = 66 + (6.23 x w) + (12.7 x h) - (6.76 x a)
Where: w = weight in pounds, h = height in inches, a = age
◦ Metric BMR Formula For women: BMR = (9.563 x w) + (1.85 x h) - (4.676 x a) + 655.1 For men: BMR = (13.75 x w) + (5.003 x h) - (6.755 x a) + 66.5
Where: w = weight in kg, h = height in cm, a = age

BMR gives the information of the energy spend at the state of resting It has to adjust with the actual activity level
Multiply the BMR by a factor called Activity Factor.
The activity levels for BMR adjustment
Activity Factor Category Definition
1.2 Sedentary Little or no exercise and desk job
1.375 Lightly Active Light exercise or sports 1-3 days a week
1.55 Moderately Active Moderate exercise or sports 3-5 days a week
1.725 Very Active Hard exercise or sports 6-7 days a week 4

BMI and BMR formulas are applied as the main mathematical model to evaluate appropriate food menus for the users.
It can suggest the range of suitable weight corresponding to normal weight for inputting the expected weight
It can offer the options of reducing rate of calories
Users can efficiently schedule the meals through this system with its user interface friendly.
