Let me see if I've got this right: you want to lose weight with minimal effort and inconvenience, plan no exercise on your own, and want to keep eating the same diet that has caused you to gain weight. I can't say that sounds very promising.

Losing weight doesn't require "will-power" -- it requires a willing and wanted change in lifestyle. You have to care more about your health and/or appearance than you care about whole milk, fried food, and the Friday buffet at the Ritz. You have to learn (and interalize) a true preference for fruit over chocolate, yogurt over ice cream, grilled over deep-fried. You know (hell, everybody knows) that it can't be a miminal and temporary (i.e., anomalous) change of routine. You can't get two hours of exercise a week and then "reward" yourself with a Happy Meal afterwards. And you can't pay someone to do it for you.
