While I had stopped eating wheat and red meat for a couple of weeks prior, March 12 was my first day on the 1000-calorie diet.
Now that it's april 12, I am going to increase my daily calorie intake slightly - and increase my running as well. I'll aim for 1200-1400 calories per day, and run about ten miles per week.
By July, I'll be eating something between 2000 and 3000 calories a day, and running 20 miles per week.
peak marathon training, 45 miles per week, and as many calories as I need to support that (and maintain weight)
