The other day I was really hungry around 4:00 pm, and I knew I wasn't going to eat dinner until 6:45 or so. It took a lot of willpower (and a couple of big glasses of water) to hold off on eating anything, but I'd done so well for most of the day that I didn't want to waste all of my effort at that point.
I could have had a bigger lunch, but I didn't, because I'm trying to eat less. So those couple of hours of hunger would have been for nothing, had I eaten more - it's not that I would have had so much to have gained weight, but I probably would've negated anything I did that day to lose.
I was willing to be hungry. I wasn't going to die, and I wasn't at the hangry/cranky stage where eating something is necessary to save a relationship (come on, we've all been there...you know that "eat a Snickers" commercial IS telling the truth)(although you can achieve the same results with eating something healthier than a Snickers)(but damn, a Snickers bar is pretty good). The hunger was worth the reward.
Dieting isn't about the big things. It's about the day-to-day stuff you do, the little changes, the acceptance of being a little uncomfortable, that makes it work. This also applies to maintaining that weight loss - much as I'd like to not have to think about what I'm eating, it just doesn't work that way. As I'm in the midst of doing both at the moment (dieting on the weekdays, maintaining on the weekends), I'm realizing how many small, but significant, sacrifices I'm making on a daily basis in order to achieve my goal. I'll be honest - some days, I'm going on a day-to-day effort, because thinking about being hungry again doesn't sound all that appealing. But the results of these efforts are appealing to me, and for that reason, I'm willing to make these small sacrifices.
