For those of you concerned about energy expenditure, use Blackle instead of Google. Same search engine, more green.

So I read the calorie guidelines more carefully, and I am supposed to be burning 500-750 more calories than I take in each day, not 300 like I had been doing. Yesterday I got it up to 500 because of a long, one hour walk we took. Guess that will be the minimum goal from now on. 500 calories per day equals loss of 1 pound a week, as 1 pound of fat equals 3500 calories.
