Write it down immediately
"Write down what you eat, when you’re eating it," says dietitian Lisa Renn. "If you do it at the end of a day, there’s a good chance you’ll forget to include some of the things you’ve eaten, particularly snacks, which tend to fly under the radar."
Don’t skip the details
Record what you’re doing or feeling when you’re eating, for example, snacking whenever you sit down in front of the TV, or raiding the fridge if you’re stressed. Identifying such patterns can help you modify them.
There’s no point in not being honest about what you’ve eaten, says Renn. If you leave things off the list, you – or the dietitian helping you – won’t be able to spot any potential areas for improvement that may explain whatever issue you’re having. If you are seeing a dietitian, remember they’re not there to judge you, but they do need all of the information in order to do the best job.
