on over-shopping

or rather, on my new strategy for NOT buying too much.

now that M and i are on the zone diet -- which isn't working all that well for me on the weight loss, but is working terrificly on the health & wellbeing part -- i have to do tons of veggie shopping, on my bike!

this seems to be a good strategy for not over shopping. i mean, when i have a zipcar, i go overboard, and i don't think of being conservative in my purchases, b/c i'll be able to get them all home. think Target. huge carload of stuff every time i go (with the zipcar).

now, on the bike, i have to consider whether i am going to consume all the things that i buy in a reasonable amount of time. if i am not going to eat them within a few days - i just don't buy them. and, that requires another trip on the bike. burning more calories to justify more food.

i wonder if shopping weren't so easy - if it requires all the effort it takes me for example to get to the store - would there even be places like cost-co? or would we find other ways of overshopping?
