Tweet what you eat

With the service from Tweetwhatyoueat, you can keep track of what you eat throughout the day. To use the service, add Tweetwhatyoueat (named twye) and direct message it  with your meals and snacks throughout the day. You can send in messages from the web, your phone, IM, or your Twitter client. Tweetwhatyoueat will create a food diary based on your DMs, calculating your calorie totals as you go.
