your telling us you want to lose weight, you know what the problems/solutions are, but they are too hard so your not going to do anything about it. not to be a dick here but all you are doing is making excuses for yourself...i really dont think your ready for a lifestyle change that will give you the results your looking for. losing a significant amount of weight isnt a hobby you pickup when you feel like it, its a 24 hour job. this is not a diet you will be on...this is a lifestyle change.
personally i would head over to
www.bodybuilding.com and read their nutrition and fatloss forums. learn what your body needs to achieve the goal you have set so you can tailor your own 'diet' that fits your needs. plus there are lots of other people there in the same boat as you which might help your motivation when you see their before and after pictures.
i jumped around on a couple of diets trying to shed 50lbs i was carrying around. i was defeated just like yourself. i tried all i could do and the weight just wouldnt come off. after learning what MY body needed to achieve my goal i change my lifestyle to accomdate things and poof....i dropped the weight in a year and look like a new person.
get strong and just do it.
