Returning to fitness, week 1

I ran 2 to 4 miles most days, did 60 to 70 sit-ups most days, and changed nothing about my diet. This week, my weight is 198, which is 4 pounds less than my original weight. I'm glad to be losing weight, but oh how it hurts to do this. My muscles ache, and my body is exhausted every night. Hopefully I'll adapt soon. I've not yet changed my diet much.
