For the first several months, I kept food logs, until my meals and shopping became automatic. It can be a pain, but one way to track meals is simply to use your phone to photograph (and upload to a dedicated FB page?) everything you eat.
You should pick the way of recording food and exercise that works best for you – a study shows you’ll be more likely to maintain the habit of keeping logs. People who keep logs do lose more weight!
I record my exercise and daily weights in my on-line Google calendar… but that’s me. See this link for some samples of food logs.
This link discusses an iPhone app that let’s you track bar codes of what you eat. The problem, though, is that humans weren’t designed to eat bar-coded food!
