Weight Tracker is a Flask application you can use to track and then predict your weight based on your habits.

I got sick of having to track all my food down to the calorie when I can predict outcomes based on overall trends and tracking a few key metrics - weight, body fat %, and a few body measurements along with supplements and eating habits.


Running Weight Tracker

Install all of the required Python libraries.

pip install flask
pip install flask-script
pip install WTForms
pip install mongoengine
pip install flask_mongoengine
pip install parsedatetime

Download, install and then run MongoDB

Rename config/example-config.ini to config/config.ini

At a minimum, fill in the details for your MongoDB installation in the MongoDB section of the config file.

In the root directory, run the following command (on Mac or Linux) to make the manage.py file executable

chmod a+x ./manage.py

Run the index.py file to start Weight Tracker

python manage.py runserver

Start tracking your stats by browsing to http://localhost:5000
