In my experience, i started getting fat when i started to become constantly stressed (due to work, life, etc.) Seems odd isn't it? I think it's the tendency to become more hungry once you're stressed (i read about some scienctific explanation for that somewhere). And since most of us here in the GCC are working not just for our own selves but for families abroad, i think we live with a "work, house, sleep, and off to work again" routine. So, when work is over i'd be tired and hungry so i just eat and sleep. And the next day would have the similar routine again. and although jogging and exercise would be the best solution, but when you've been drained out of strength and sense throughout the day all you could long for is some haagen daaz and a soft pillow under your head :)

...but i've been pulling myself into jogging now, hehe
