Nutrition Calculator

The project is a simple nutrition calculator that using Harris–Benedict equation revised by Mifflin and St Jeor.

Step 1. Individual's basal metabolic rate (BMR)

Sex	BMR
Men	BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5
Women	BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161

Step 2. Total Intake

Lifestyle	Example	PAL	Calculation
No activity	No any sport activities per week	1.2	BMR x 1.2
Low activity	1 - 3 workouts by 30 minutes per week	1.375	BMR x 1.375
Sedentary or light activity	3 - 5 workouts by 30 minutes per week	1.53	BMR x 1.53
Active or moderately active	Construction worker or person running one hour daily	1.76	BMR x 1.76
Vigorously active	Agricultural worker (non mechanized) or person swimming two hours daily	2.25	BMR x 2.25
