Add a page to calculate TDEE: Total Daily Energy Expenditure

[amritav]

Issue Description

TDEE (Total Daily Energy Expenditure) is a critical metric for individuals managing their nutrition and fitness goals, and having this feature within the app would greatly enhance its utility. Hence there should be a TDEE calculator page in the application as it:

• Empowers users to set and manage their nutrition goals more effectively.
• Enhances the overall utility of the BurnOut application by providing a comprehensive tool for health-conscious individuals.
• Attracts users interested in fitness and nutrition planning.

Feature Details

• TDEE Calculation: The TDEE calculator should take into account user input for factors such as age, gender, weight, height, activity level, and possibly other relevant parameters. It should then provide an accurate estimate of the user's Total Daily Energy Expenditure.

• User-Friendly Interface: The TDEE calculator page should have an intuitive and user-friendly interface that guides users through the input process and provides clear, easy-to-understand results.

• Informative Output: After calculating TDEE, the page should display a breakdown of daily caloric needs for different goals and provide recommendations for calorie intake, macronutrient distribution, and possibly meal planning.

• Customization: Users should have the option to customize their goals, such as weight loss, maintenance, or muscle gain, which can then be factored into the TDEE calculation.

Scope of Impact

Implementation Ideas

• Consider using established formulas for TDEE calculation, such as the Harris-Benedict Equation or the Mifflin-St Jeor Equation, as a basis for the calculator.

We can use the following formula to calculate TDEE incase we do not have Bodyfat% details: Step 1: Calculate BMR Mifflin-St Jeor Equation BMR = (10.m + 6.25h - 5.0a) + s m is mass in kg, h is height in cm, a is age in years, s is +5 for males and -161 for females

Step 2: Calculate TDEE Here are the different activity factors and their corresponding activity levels: TDEE = alf * BMR alf values: Sedentary: 1.2 Lightly active: 1.375 Moderately active: 1.55 Very active: 1.725 Super active: 1.9

We can use the following formula to calculate TDEE incase we do have Bodyfat% details: Step 1: Calculate BMR Katch-McArdle Equation Lean Body Mass = m (1-bf) BMR = 370 + (21.6 LBM) where LBM is lean body mass, m is mass in kg, bf is body fat percentage in percentage.

Step 2: Calculate TDEE Here are the different activity factors and their corresponding activity levels: TDEE = alf * BMR alf values: Sedentary: 1.2 Lightly active: 1.375 Moderately active: 1.55 Very active: 1.725 Super active: 1.9
