I decided that tweeting what I was eating was getting a bit tiring (and potentially tiresome). It was still a useful exercise -- it got me to be consistent with tracking, and more conscious of my choices. I may save it as a fallback strategy for when I want to keep myself more attentive and accountable.
I think Vickie is also right in her comment -- if I'm feeling defensive about the idea that other people might be judging my choices, why make those choices so public? I was hoping to demonstrate that it's possible to choose from the full range of foods, eat satisfying meals, and still lose weight. Still, a one-person experiment is not going to definitively prove that, especially a one-week, one-person experiment.
I like the Nutrition Diva's podcast because her ideas are so sensible. She recently said, "There are two kinds of people, those who feel the need to divide everything into two categories, and those who don't." She was talking about all of the studies that look at this food or that food in an effort to see what is "good" or "bad" for us. Instead of looking at one food and declaring it healthy or unhealthy, it's better to look at the whole balance of the diet. If anyone really wanted to do a truly effective nutrition study, they would have the subjects photograph every meal and snack and analyze the diet as a whole.
As for me, I'm going to keep working on tweaking my own diet according to my own nutritional philosophies and worry less about whether other people approve. Maybe once I'm a big weight-loss success, I'll let you in on all my secrets.
