Quick weight loss

My Philippine trip is fast approaching and i really want to lose weight because i don't want my family, cousins or friends makes fun of my body changes. I left Phils. 4years ago with a weight of 110lbs and now i am close to 130lbs. I am always wanting to lose weight but the festive holidays got me into this. From thanksgiving, christmas, new years and friends dinner invitations, i can't really get away with it. Another thing is there is also a weird feeling inside of me from the time i get off from bed, i always thought about cooking and eating aside from being a couch-potato all day. Okay, i'm lazy. I hate doing an exercise and simply hate of being tired. My stability ball is just right around the corner of the house waiting for me. Husband says, he wasted his 30 dollars to buy for it. Is there any quick weight loss tip for a lazy type of a person like me? lol
