It's pretty easy to drop 5lbs in a day by simply fasting. Getting in the habit of fasting through a single meal here and there and only eating when you are actually hungry can have a dramatic impact. Break fast with something small like a granola bar and waiting until you feel hunger again before eating something small and suddenly you stomach will shrink (it's a lot cheaper than getting your stomach stapled) and your issues will suddenly become things like needing to buy new clothes because you can't keep your pants up and the fold in the waist of your jeans is pinching you under your belt.
