Weight loss confirmed

Remember when I thought I had lost some weight or inches last month because my clothes felt more loose? The other day I tried on the red dress that I bought in Singapore years ago when I was much fitter and slimmer, and it fitted! Then today I confirmed that I had lost weight, six pounds to be exact because I'm down to 110lbs. I haven't been making any conscious effort to lose weight so it's a bit of a mystery why that happened. But there's a possible explanation: I've been aware that I haven't been as hungry as usual between meals lately and hence have not been eating snacks in the morning and afternoon at work. Due to less stress perhaps?
