# Makefile for diet and weight-loss monitoring
# vim: ts=8 sw=8 noexpandtab nosmarttab
#
# Goal:
#	- Find out which lifestyle factors affect your weight the most
#	- Find out which foods make you gain or lose weight
#
# Requires you to:
#	- Weight yourself once a day
#	- Record what you do/eat daily
#
# How to run this code:
#	- Install vowpal-wabbit & its utility utl/vw-varinfo
#	- Clone this repo: https://github.com/arielf/weight-loss
#	- Place your data in <username>.csv
#	- Type 'make'
