Users have to choose if they are registering as a personal trainer or client, as it will affect their registration process.
This step is identical for both types of users.
Here, clients will let the app know if they have an existing personal trainer they are engaging, using the referral code that the personal trainer will provide. Otherwise, they can also register and use the app without a personal trainer.
The personal trainer may upload a picture of their certificate.
This page serves the purpose of gathering the client's current biometric details, which will be used to compute their daily calorie intake goal. This can be edited by their personal trainer or by themselves.
/* Calculates the target calories for a user */
/* Inputs
- Weight (in kg)
- Height (in cm)
- Age (in years)
- Gender (0 for male, 1 for female)
- Activity Level (0, 1, 2, 3, 4)
Output
- Total caloric expenditure
-> user will eat MORE or LESS calories than this, depending on goal
*/
export default function calculateCalories(weight, height, age, gender, activityLevel) {
// FIRST STEP: Calculate BMR (different for males and females)
const maleBMR = (10 * Number(weight)) + (6.25 * Number(height)) - (5 * Number(age)) + 5;
const femaleBMR = (10 * Number(weight)) + (6.25 * Number(height)) - (5 * Number(age)) - 161;
// SECOND STEP: Multiply by specified activity level
/* TO DETERMINE WHICH MULTIPLIER TO USE,
- Sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
- Lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375
- Moderately active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
- Very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
- If you are extra active (very hard exercise/sports & a physical job) : Calorie-Calculation = BMR x 1.9
