You should take ...... of protein per day

This Protein Intake Calculator will tell us how much protein to eat per day.

## Just add the values step by step and multiply by weight in the end.

If Age is (let user put his age, don’t give age group in input/placeholder)
Age <14 is not applied here. This Protein Intake Calculator is for age <14.

Age Metric Standard
14-18 0.9 gram 0.00198416 lbs
19-30 0.8 gram 0.0017637 lbs
31-40 0.9 gram 0.00198416 lbs
41-50 1 gram 0.00220462 lbs
51-60 1.1 gram 0.00242508 lbs
61-70 1.2 gram 0.00264555 lbs
71-80 1.3 gram 0.00286601 lbs

## Choose one number as per age and forward to next step

If Sex is –
Male – then no change to this table- Just follow
Female- then (- 0.1 gram , in Metric) and (-0.000220462 lbs , in standard)
Example- If the person is Man , aged- 25
Take – 0.8 gram (Metric) or 0.0017637 lbs (standard)
If the person is woman , aged – 25
Take- (0.8 – 0.1) gram or (0.0017637 – 0.000220462) lbs

## Now we go with the results to next part-

Activity Level-
If Activity Level is-
Sedentary – No Change
Lightly Active- Add (0.2 gram) or (0.000440925 lbs)
Moderately Active- Add (0.5 gram) or (0.00110231 lbs)
Very Active- Add (0.8 gram) or (0.0017637 lbs)

## Protein Intake Calculator. Now we go with the results to next part-

Goal –
If Goal is-

If Fat Loss – then
Calculate BMI of the Person
Formula for BMI
In Metric- BMI = [weight (kg) / height (cm) / height (cm)] x 10,000
In Standard- BMI = [weight (lb) / height (in) / height (in)] x 703

If BMI is Metric (Add) Standard (Add)

24 1.8 gram 0.00396832 lbs
25-30 2.1 gram 0.004629708 lbs
31-35 2.0 gram 0.00440925 lbs
36-40 1.9 gram 0.004188783 lbs
41-45 1.7 gram 0.003747858 lbs
46-50 1.5 gram 0.003306934 lbs
50 1.3 gram 0.002866009 lbs

If Maintenance – then
No change
If Muscle Gain – then

## Add (0.6 gram) or (0.00132277 lbs)

Now Multiply the end result with the “Weight” of the person
In Metric- (End result * Weight of the person (kg)= â€¦.. gram of protein
In Standard – {(End result /2.20462)* Weight of the person lbs} = â€¦.. lbs of protein
