A run in the morning is such a great thing and indeed does work as stated. I used to do this but after a while I got sick of getting up early hours, so I devoted my running time to late at night, around 9.30 - this way you are burning off excess carbs before you go to bed and wont be putting weight on as they say in your sleep. My running is getting so much easier only after a few tries and it really does help.
Best wishes
