Wanna lose weight comfortably? Here’s a script that I wrote to i) test the WWW::Mechanize module with forms and to ii) make it easy for me to update entries in www.fitday.com. Note that this script adds complex food that you eat regularly to your daily food recording; in this case it is a chicken wrap. You will have to add the ingredients yourself first through the FitDay search pages. Then you can add them to the array in the code below. After running the script change the amounts you consumed.
 
use strict;
use WWW::Mechanize;
use HTML::Form;
use HTTP::Cookies;
#use LWP;
my $mech = WWW::Mechanize->new( autocheck => 1 );
my $form_name="loginForm";
my $Fname;
