I have been doing a.m. Fasted cardio for about a week now. I'm trying to break through a weighloss plateau. Been stuck at 210 lbs for a few weeks. I am down from 245 from 6 months ago. Anyway my question is I haven't changed my diet but after starting fasted cardio. I've been much hungrier through the day. I space my meals every 3 hrs. 7am,10,1pm,4 and 7 pm. I find my self having to eat my 1 o'clock around 12. And not only earlier but still hungry shortly after. Could it just be my metabolism is speeding up. I am down 2 lbs in a week as well.
