Just some history. I've never been a long distance runner. EVER. I was always a sprinter. So from going to running half a mile to 3.1 miles is crazy. Crazy in my mind anyways. I can barely even run 1 mile on the treadmill because my lung capacity (VO2 max) is pretty low. I also want to lose 25-30lbs. I'm currently fluctuating from 173-178lbs and I want to get down to 140-145.

Anyways my question is, how soon will I start to lose weight? Right now I've been working out hard for 2-3 weeks and I have not lost ANY weight. I eat pretty healthy and I don't over endulge. You think I replaced fat with muscle with all the weight lifting I have been doing? I also think I need to eat a healthier breakfast and drink more water. I probably drink 4 cups a day right now.

Any feedback or shared experience is greatly appreciated!
