Consuming foods in abundance

I ate gorditas and fries, which I consumed in abundance.  I didn't follow my plan fully which has me a bit bummed, but I have to realize that I tend to change my mind and that all plans are subject to change, so I am okay with a little change.  I am just not hungry, that is all.  I did however, drink a lot of water which should be of benefit to me.  I will check out my past entries and check what I need to do to improve on what I have as far as following a meal plan and eating healthy.  I have to also recall that losing weight is about a combination of diet and exercise with diet being dominant as compared to exercise.  Or is it the other way around?  Or are they both equal?
