Finding my limits

So I fasted two meals Sunday (total calories ~500) and walked about a bit, expending more than sedentary would.

I fasted two meals Monday (total calories a bit less than 500) and exercised about double what I usually would. My energy level, despite the previous and current day's fast, was fantastic yesterday.

I was going to eat only fruit leading up to my evening meal today, as a sort of cleanse. Tried to exercise, but could only do about 30 minutes of cardio and really pooped out during strength training. And I got light-headed around 3:00 and decided I needed to eat a meal.

Lesson learned: Just barely over 1000 calories is not enough nutrition to sustain me into the third day.

Lesson number two: I lost a total of about four pounds in two days. That's a good beginning. Am weakish right now, and looking forward to a good, filling dinner.

Oddly, am not struggling with hunger pangs or cravings. No sugar three days now, though the cupboard is full of it. *shrug* I never know why things go well, I'm just glad they do.
