Planned no meals

I took a break from planning meals today.  Needless to say I ate more in desserts than I did in healthy foods. I need to change that and I want to, but I don't know how.  It is not doing me any good that I have diet issues and I am exercising.  I am tired of the "instead of this, I should have eaten this" line.  It is now time to reflect with no procrastination.
