Process-1
Step-1
Calculate BMI- Weight (in Kg)/Height * Height (in meter)
If the result is <25 then We will skip to step -2 (for result of process-1)
If the result is >25 then ; the result for process-1 = Weight (in pound)*0.666666 = result in ounce (oz)
—-
If the result was <25 then follow this table to get result of process-1
Age Group | Water intake in ml | |
Female | 14-18 | 2300 |
19-30 | 2700 | |
31-50 | 2700 | |
50+ | 2700 | |
Male | 14-18 | 3300 |
19-30 | 3700 | |
31-50 | 3700 | |
50+ | 3700 |
Now we get result for Process-1
————————————————————————————————————
Process-2
Season-
If Winter – (-10% Change of process-1)
If Normal – (0% Change of process-1)
If Summer- (+10% Change of process-1)
Now we get result for process-2
———————————————————————————————————————-
Process-3
Activity Level-
If Lightly Active (Sedentary) – (0% Change of process-2)
If Moderately Active – (+10% Change of process-2)
If Very Active- (+20% Change of process-2)
