Has anyone experienced such a difference in results when eating clean compared to eating some processed foods. I mean, does having a little sugar in your oatmeal fatten you up, even if you make sure to reduce the size of the oatmeal portion to make up for the calories? I mean, what is the real difference between a 300 calorie bowl of all natural oatmeal, vs. a 250 calorie bowl of natural oatmeal with 50 calories of sugar on top?
