In our house, we have a few rules that we try to stick to:
1. Limit red meat to 1x per week
2. Limit salt (we use herbs and seasonings instead)
3. Only eat things that we can pronounce (not too keen on the ingredient lists that read like science experiments)
4. Limit HFCS as much as possible
5. Work the whole grains and high fiber stuff
6. Switch to organic when possible
7. No sodas (we stick to water, green tea, milk, and the fruit juice we use to make our morning fruit smoothies)
I'm also keeping a food log as a tool to help shed the last few pounds I want to drop.

It's really been a big help to me to think about what I'm putting in my body and why (am I
really hungry, or am I just bored and looking for something to do?).
We've managed to follow these rules for around 3 1/2 months now. It's been really great - and the longest we've ever managed to stick with something like this. We have much more energy and actually want to get out of the house and go do stuff, where before I mostly wanted to stay home and nap on weekends.
