Just remember that one day of not reaching your goal doesn't make a failure. Over the long haul, keeping at this, will have good results. Just like one bad meal won't make a slim person fat... nor will one good meal make a heavy person slim...it's the overall average of what we eat that shows. Exercise is that way too...and maybe moreso if you add in the weight, as muscles weigh more than fat. But you know (you DO know, I know) that toned muscles burn more fat..so in the long haul, you're good to go!
