It's not the flashiest thing, but I lost a bunch of weight (over 50 lbs) using a spreadsheet. The way I did it, I had one sheet with the macronutrients (including calories) and serving sizes of food I encountered, or recipes I made. This sheet got very large by the end. When I ate something, I'd copy out the row and paste it into a daily sheet that totaled everything up. The downside is that it's not easy to add new foods, since I'd have to manually input everything. I almost consider this a feature, because sometimes I'd skip snacking because I didn't want to deal with adding it to the spreadsheet.
