I'll second the value of using myfitnespal. It's cross-platform and much of the data is contributed. Very powerful software that works surprisingly well.
Don't have a source, but I've heard that people who journal their food intake are twice as likely to lose weight over those who do not journal. For many, just keeping a record of how much you consume helps keep it under control. Adding light to moderate exercise on top of it, and that's 90% of everything you need to know to effectively lose weight.
