I found when I cut sugars, and bread and such, I was eating more meat and fats.  No longer was I hungry when it was meal time again.  I would eat, but didn't need eat as much.  Then I got into the intermittent fasting.  I could completely skip breakfast and not even phase me.  I would then be hungry around lunch time, but ate low carbs and would be fine until supper.  I also think it may change your metabolism some.  If you go back to some carbs like I did, the weight really didn't come back like I thought it would.  I'm back up about 5 pounds from my low, but increased my carbs quite a bit from where I was when I started this.  I still am not eating as many as before as I still stay away from sugary drinks for the most part now, but back to eating bread and desserts.
